The neurodevelopmental process is orchestrated by a series of intrinsic

The neurodevelopmental process is orchestrated by a series of intrinsic mechanisms and extrinsic cues. Among these, intrinsic epigenetic regulation plays an important role in neural progenitor fate specification and provides one explanation about the complexity of developmental processes. DNA methylation in the form of 5-methylcytosine (5mC) is essential for normal development in mammals and influences a variety of biological processes, including transcriptional regulation, imprinting, and the maintenance of genomic stability. Hydroxymethylcytosine is emerging as the active demethylation modification that targets a specific 5-methyl group on cytosine for net removal by a complex GSK J4 excision repair mechanism (Guo et al., 2011a, 2011b). Consistent with the idea that hydroxymethylcytosine is involved as a specific mechanism for active cytosine demethylation, recent studies identified the ten-eleven translocation (TET) family of proteins in active DNA demethylation (Ito et al., 2010; Tahiliani et al., 2009). The three mammalian TET proteins, TET1, TET2, and TET3, have changed our understanding of the process of DNA demethylation as they can oxidize 5mC to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (5caC) (He et al., 2011; Ito et al., 2010; Tahiliani et al., 2009). Recent studies have shown that TET-mediated DNA demethylation can play vital roles in various biological processes, not only in development but also in disease. Despite these advances, the functions of TET proteins and their regulation in brain development need further investigation.
Here, we report the unique roles of MCPIP1 during early neocortical development. We found a dramatic expression pattern of MCPIP1 during early cortical neurogenesis. MCPIP1 regulates various aspects of neurogenesis. Notably, we observed that MCPIP1 directly targets Tets, and represses TET and 5hmC expression levels. Importantly, the interaction of MCPIP1 and TETs is involved in neurogenesis and NPC pool maintenance. Our current data demonstrate a direct and important molecular link between the immune regulatory molecule, TETs, and epigenetic regulation.


Although the brain has traditionally been regarded as immune-privileged, many studies suggest that there is extensive communication between the immune system and the nervous system in both healthy and diseased conditions. We sought here to learn about the basic roles of specific and crucial immune molecules in the nervous system. We observed that MCPIP1 was abundant in early neural progenitors and that its expression decreased over time during early mouse neocortical development. In the murine cortex, neurogenesis begins at approximately E12, reaches a peak at approximately E15, and terminates at approximately E18 (Qian et al., 2000). Therefore, MCPIP1 expression in the developing neocortex suggested precise temporal and spatial roles for MCPIP1 during this period. We identified these roles by demonstrating that altered Mcpip1 expression resulted in changes of various aspects of neurogenesis. Notably, the composition of the neural progenitor pool was altered following Mcpip1 expression variation, resulting in a change in the relative proportion of apical progenitors to basal progenitors. A potentially interesting possibility was explored, showing that MCPIP1 inhibited apical progenitor generation but promoted its transition.
Next, we investigated the underlying mechanism for MCPIP1 in early cortical neurogenesis. It is known that active DNA demethylation is prevalent in mammals (Tan and Shi, 2012). TET proteins were recently identified as enzymes that promote DNA demethylation (Ito et al., 2010; Tahiliani et al., 2009). Direct regulation of Tet expression should be a rather straightforward means of modulating the level of DNA modification. Although regulation of Tet expression at the transcriptional level is well documented (Fu et al., 2013; Song et al., 2013), insights into the direct regulation of Tet mRNA by an RNA-binding protein are reported herein.

The CC chip is compatible with many PCB

The CC1110 chip is compatible with many PCB mounted antennas including a DN024 antenna that is used in a RCS and microcontroller unit as a transmitting and a receiving antenna respectively. An RCS controls CPLLS according to the program entered by the operator manually after pressing the ‘ON’ button and setting the color temperature using the light intensity control button. In the standby mode the CPLLS power consumption is less than 0.5W.
Circuit design and technical specification of the RF Fmoc-Leu-OH of a RCS and the control microcontroller of EDCLLS are identical because the same module—ZigBit 2.4GHz Single chip Wireless Module ATZB-S1-256-3-0-С [5] supporting IEEE 802.15.4 standard is used. The module has high sensitivity (−97dB at error rate BER 1%) and optimal transmitter output power of +3dBm result in unique power budget (up to 100.6dB) of the link. The range of the radio control link in free space if the transceivers are positioned at the height of 0.5m above ground is 170–570m. This is achieved for various combinations of the transceivers’ orientations (polarizations) and in the absence of interference from other transmitters. In real life situations multi-path propagation, interference and other factors can significantly reduce the range of the radio control link.

Model of radio control link
The idealized model of a radio control link is often described by the Friis transmission equation [6]:
where is a power available at the receiving antenna; is a power supplied to the transmitting antenna; are the gains of the receiving and the transmitting antennas, respectively; λ is the wavelength (λ=c/f, c is the light speed in vacuum, f is the frequency), d is the distance between two antennas (the projection on the Earth\’s surface), n is the path loss exponent.
Eq. (1) is often used to determine the power budget of a radio control link. In real control links the waves are reflected and obstructed by all objects illuminated by the transmitting antenna. In this paper, a two-ray interference model is used where the ground reflecting incident wave toward the transmitting antenna influences the radiation pattern. The interference of the two rays at a receiving antenna produces a particular multi-lobe field structure.
Fig. 1 represents schematically the position where there is an infinite, perfectly flat ground plane and there are no other objects obstructing the signal path.
Points A and B show the positions of the transmitting and the receiving antennas. The field at the receiving antenna is a sum of the direct ray and the ray reflected from the ground (secondary wave). The paths of the rays are R1 and R2, respectively, the length of the control link R =d, the heights of the transmitting and receiving antennas are h1 and h2, it is assumed that h1>λ and h2>λ. The effect of the reflected ray can be imitated by a fictional source located under the Earth\’s surface symmetrically to the real source.
In sufficiently long control links R ≫h1, h2 and the rays AB and A′B can be assumed to be parallel, the difference in distance travelled by the rays R2–R1 is
that is much smaller than R and in calculations of the amplitudes of the direct and the reflected rays it is possible to assume

With these assumptions the interference formula describing the power at the receiving antenna is given by
where V is the ground influence factor depending on the heights of the antennas above the ground, the reflectivity of the ground and the antennas’ radiation pattern.
Other factors are the same as in the Friis transmission equation. The reflected ray is formed by an area of the ground\’s surface that is determined by the first Fresnel\’s zone. The Fresnel\’s zone is shaped like an ellipse with the long axis oriented in the direction of the wave propagation. The lengths of the short and the long axes (see Fig. 1) are, respectively

The assumption of the direct and reflected rays being parallel needs additional clarification in case of RSD radio control links. In actuality,

Although it appears that hypercortisolemia

Although it appears that hypercortisolemia may contribute to the development of different features of metabolic syndrome, it is not clear in the literature whether glucocorticoids play a role in the pathogenesis of obesity. Some studies show that Ro3306 levels are not higher in obese subjects, and sometimes they are even lower than in lean subjects [107,108]. This may be, at least in part, a consequence of enhanced cortisol clearance that is thought to accompany obesity, for instance, through increased activity of 5α-reductase in the liver [108]. Mean 24h plasmatic ACTH levels were positively correlated with body mass index, reflecting increased hypothalamic drive and reduced negative feedback of cortisol in obesity [109].
Other factors related to cortisol action are also determinants. In this sense, the local expression of 11β-hydroxysteroid dehydrogenase 1 (11β-HSD1) plays a role in the relationship between cortisol, adiposity, and metabolic disease [110]. The enzyme 11β-HSD1, expressed in several peripheral tissues, such as liver ad adipose tissue, can modulate HPA axis activity, regenerating active cortisol from its inactive form intracellularly [111]. In humans, 11β-HSD1 expression is increased in subcutaneous adipose tissue from obese subjects compared to lean subjects [112], being stimulated by TNFα, leptin and adipokines [113,114].
In the presence of insulin, cortisol promotes triglyceride accumulation, mainly in visceral adipocytes, thus leading to increased central adiposity. Masuzaki and colleagues have also demonstrated that overexpression of 11β-HSD1 in adipose tissue resulted in visceral obesity and metabolic syndrome in mice fed with a high-fat diet [115]. Adipose tissue that overexpressed 11β-HSD2, the enzyme that inactivates cortisol, protected mice from high-fat diet-induced obesity [116]. The modulation of 11β-HSD1 might be a promising therapeutic target for obesity and metabolic disturbances. Studies focusing the inhibition of 11β-HSD1 in animal models of diabetes and obesity have shown improvement of insulin resistance and glucose levels, beyond weight loss [117,118].
Dysregulation of the HPA axis has been associated with some eating disorders [119,120], mainly due to changes in insulin, NPY levels, and other peptides implicated in food intake regulation that can be modulated by cortisol metabolism [112]. Food intake is stimulated by administration of glucocorticoid prednisone in healthy men [121], while diet influences cortisol metabolism, affecting the HPA axis and the reward circuitry for palatable foods [112,122]. Important effects of altered cortisol levels on weight gain are also reported in Cushing׳s syndrome and Addison׳s disease, which are both associated with effects such as central obesity/hypercortisolism and weight loss/hypocortisolism, respectively [123].

Sleep, stress, and metabolism
Because of the new lifestyle imposed by work and family, physical and psychological problems, and social changes due to internet and television, stress and sleep restriction have become endemic, with a major impact on the metabolic process. Importantly, stress hormone levels correlate positively with decreased sleep duration, while both are associated with obesity, metabolic syndrome, and eating disorders [73]. A study by Galvao and colleagues [124] showed that rats subjected to 96h of paradoxical sleep deprivation present increased immunoreactivity for CRH and orexin as well as higher levels of ACTH and corticosterone, in addition to increased diurnal food intake, but without changes in global food intake. A negative correlation was found between corticosterone and body weight gain throughout paradoxical sleep deprivation [124].
Stress is known to reduce SWS, REM sleep, and delta power, as well as to affect metabolism in rodents, with the magnitude varying according to the type and duration of stress exposure [73]. Sleep deprivation, in turn, activates many stress-related pathways including the HPA axis and sympathetic nervous system, which indirectly modulate arousal and affect the metabolism [26,125]. It has been proposed that the bidirectional relationship between sleep and stress and its impact on metabolism are, in part, mediated by hypocretin circuitry. Hypocretinergic cells project to several CRH-responsive regions in the central nervous system, including locus coeruleus, the PVN, the bed nucleus of the stria terminalis and the central amygdala [126].

The literature shows scarce efforts made for the development of

The literature shows scarce efforts made for the development of diagnostic tools and devices with potential for effective monitoring of chronic wounds. Matzeu et al. [14] demonstrated an RFID-based skin temperature monitoring system obtaining a 0.2°C temperature measurement accuracy. A flexible platinum-based miniaturized temperature sensor is proposed by Moser and Martin [15] to operate within 0-400°C range. However, the sensor has not been used in wound dressings. McColl et al. [16] have developed an impedance sensor-based moisture monitoring system for wound dressings. Based on this principle, Ohmedics© has developed a commercial moisture monitoring device called WoundSense® [17]. However, the sensing system is not designed to stay within the dressing for continuous moisture measurement. To date, no device exists for continuous monitoring of sub-bandage pressure, though some sub-bandage pressure meters, such as Kikuhime®, are in practice, but they have very limited clinical application. Miniaturized pressure sensors have been designed and used for other applications such as intracranial pressure (Codman® [18] and Mejzlik [19]), intraocular pressure (Ning et al. [20]), spinal plates pressure (Sauser et al. [21]) and for general in-vivo applications (Clausen et al. [22], Willyan et al. [23] and Hill et al. [24]).
For a wound monitoring system, calibration and characterization of sensors is important in order to sense accurate information beneath the dressing. Incorrect sensor measurements will negatively impact on clinical decisions about the wound under observation. In our recent review article [25], we have highlighted the gap in potential use of modern sensors and wireless technology for wound monitoring applications. In this paper, we present methods for calibration and characterization of temperature, moisture, and pressure sensors deemed suitable to be interfaced with a wireless telemetric sensing system. The sensors were carefully selected considering their small size, low power operation, flexibility and minimal invasiveness to the wounds. The calibrated sensors were interfaced with the developed prototype sensing system, and the performance of the system was tested by placing the system and sensors under a buy SQ 22536 bandage on a mannequin leg.

Methods and materials

Experiments using a compression bandage
For real-time validation of all the calibrated sensors working together, we designed a prototype flexible wireless transmitter (9.7cm×4.7cm) and a receiver (4cm×4cm), both operating at the radio frequency (RF) of 2.4GHz using the IEEE 802.15.4 ZigBee protocol. The sensors were interfaced with the transmitter circuit using additional interface circuits designed for impedance and voltage conditioning. Both the transmitter and the receiver use Atmel’s Atmega128RFA1 integrated circuit as transceiver, with all other required components for their proper operation. The temperature, moisture, and pressure sensors were mounted on the mannequin leg at proper positions, and then an elastic compression bandage (Coban™ 2) was wrapped over them (Fig. 8(a) and (b)). Distilled water was sprayed externally over the surface of the bandage. The data acquired by the sensors in real-time was transmitted to the nearby receiver at an interval of 5s. The receiver was attached to the computer’s serial port. On reception of the full data packet, the receiver first saved and then sent the captured data to the PC serial port (Fig. 8(c)). A graphical user interface (GUI) was designed in Visual Basic to display the real-time information on temperature, moisture, and pressure, along with capture-time values (Fig. 9).

Analysis and discussion
The real-time performance of the selected sensors was tested extensively and monitored with the designed prototype RF transceiver system. The transmitted and received data was validated using commercial temperature, moisture, and pressure meters. The average errors in temperature, moisture and pressure measurements in the system were ±1.5°C, ±3 %RH and ±2mmHg, respectively. The measurement resolutions obtained for temperature, moisture, and sub-bandage pressure were 0.15°C, 0.85–5 %RH, and 0.05–0.56mmHg respectively using a 10-bit analog to digital converter (ADC) within the RF transceiver. The temperature resolution is more than sufficient to detect temperature variations in human skin, which range from 32°C to 37°C under normal conditions [14]. The moisture and pressure measurement resolutions are not uniform owing to nonlinear characteristics of respective sensors. In actual scenario, the temperature sensor will be placed on periwound skin and not directly on top of wound. The moisture sensor could be placed inside a foam dressing (e.g. Mepilex®, Allevyn™) over the wound, while the pressure sensor could be placed near ankle to monitor sub-bandage pressure. The measurements with the temperature and the moisture sensors were location independent, while the sub-bandage pressure measurements showed dependency on the sensor location on the mannequin limb, possibly due to changes in applied pressure on to uneven surface morphology around the limb. However, the optimum position of the pressure sensor can arguably be determined during clinical experiments.

The mayor can also emphasize

The mayor can also emphasize in the improvement of teaching in the first years of the basic education cycle, to gain quota in the “2nd grade literacy” indicator. However, since 2004 the state government runs (alongside the federal government) a program called PAIC, Program for Literacy at the Appropriate Age, which acts in conjunction with all municipalities in an equal manner, ensuring the same training to teachers of the first grades, and using the same teaching material. Thus, such an indicator gives little scope for differentiation and tranylcypromine for the quota-share.
Lastly, as for the environment variable, not only is its weight in the quota low, it is a simple variable to obtain, being only necessary to gain accreditation with the Environment State Department.
As for the magnitude of the estimated ATT, in the Portuguese test scores, the impact close to 6 points is considerable when compared to the one found in Vasconcellos et al. (2009). The authors of that work evaluated the impact of the Escrevendo o Futuro (Writing the Future) program in the public schools’ performance at the Prova Brasil Portuguese tests, a project linked to the Brazilian Portuguese Olympiad, and found 1 to 2 point impacts. As for the approximately 4 points of impact in the mathematics test scores, Biondi et al. (2009) found a positive impact close to 2 points in scores for schools enrolled in the Brazilian Mathematical Olympiad. Based on such numbers, it can be said that the impact of the ICMS law change in Ceará generated a considerable effect on student proficiency.
How the municipalities generate such an effect is a question that demands more investigation, and that likely has different answers for different municipalities. But these effects are probably related to an assumption about the alignment of incentives: the programs evaluated by Vasconcellos et al. (2009) and Biondi et al. (2009) focus on encouraging students and teachers; on the other hand, the law focuses on incentives towards the mayors (increasing the available resources during his term).
Lastly, Pangaea is worth discussing about the relationship between the benefits and costs of a law change. One way to do such an analysis, from the society\’s perspective, is to observe that the change generated two movements: (i) the expected gain in the quality of basic education (identified here in this work); and (ii) a distortion of quota-shares in relation to a status quo, where some municipalities obtained gains, and others collected losses in budgetary resources (as documented in Holanda, 2012).
Considering the perspective in (i), this increase in the quality of education should be reflected in future human capital gains. And these gains, in some way, could be converted into an expected flow of financial benefit for society – since more human capital should generate more wealth. This conversion would come from the simulation of scenarios, as presented in Menezes Filho (2012).

Concluding remarks
It was also observed that the ICMS distribution rule is an incentive for the mayor to rationally focus on improving the quality of education, in detriment to health and environment indicators. This is not necessarily bad, considering that the advancements in student proficiency were considerable. But this can be an indication that the rule should be simplified, computing fewer result indicators of only one segment (health, education or environment, and not all at the same time).

Initially, we discuss some concepts regarding the tax treatment of corporate finance such as debt and equity in Brazil. Basically, the country adopts two forms of equity relief: dividends are exempted from personal taxes and there is a deduction of what Brazilians call interest on net equity (INE) of the corporate tax base. Whilst most OECD countries adopt a classical system, imputation or even split rates, it is clear that Brazil has chosen a different policy as the interest on net equity (INE) seems to be rare in the public finance world.

In these issues of Lan and

In these issues of , Lan and colleagues describe vaccine studies in a non-human primate model of MERS-CoV infection (). Building on previous studies in rhesus macaques with SARS-CoV (), the report details the efficacy of a MERS vaccine based on a recombinant SB 239063 binding domain (RBD) subunit. Their results indicate stimulation of both humoral and cellular immunity following vaccination and boost. Subsequent intra-tracheal challenge of vaccinated monkeys revealed partial protection from MERS-CoV induced pathogenesis including reduced pneumonia and viral titers. Having been tested for both SARS and MERS-CoV, the platform has potential as a rapid response vaccine approach for future emergent CoV outbreaks. Similarly, the platform could also be deployed in reservoir populations like camels that are thought to harbor the virus (). However, this RBD-based vaccine failed to produce sterilizing immunity typically sought in the context of vaccination. Overall, the results demonstrate that in the rhesus macaque model, subunit vaccines that target the receptor-binding domain of MERS-CoV can offer some level of protection, but require further refinement to induce sterilizing immunity.
While the study shows promise for the receptor binding domain-based vaccine platforms, a number of other questions remain. The rhesus macaque model, which supports MERS-CoV replication, fails to recapitulate severe disease seen in humans. As such, the level of protection in these studies may underestimate the utility of the approach or, alternatively, provides only minor protection for human disease. Further study in more pathogenic models like the marmoset or with adapted viruses is required to decipher this question. Similarly, while the RBD-based platform drives protection, other aspects of vaccine efficacy cannot be tested in the macaque model. Previous work with a double inactivated SARS-CoV had shown efficacy in young mice (); however, subsequent analysis in aged animals or with heterologous challenge revealed vaccine failure and significant immune pathology (). While not tested in experimental systems, based on reported cases, age and immuno-compromised status appears to be co-morbidity factors for MERS-CoV infection and lethality (). Therefore, testing the efficacy of any vaccine in aged and immune compromised populations must be considered. In addition, the continued reintroduction of MERS-CoV from zoonotic sources increases the likelihood of exposure to heterologous virus. With the focus of this vaccine on the RBD of MERS, the possibility of vaccine-induced immune pathology is reduced; however, in vivo testing is required to confirm this result.

, or meningococcus, frequently colonizes the oropharyngeal mucosa without causing any detectable symptoms but is also a major cause of bacterial meningitis and septicemia worldwide. The epidemiology and incidence of invasive meningococcal disease (IMD) are unpredictable over time and across geographic regions. In non-epidemic areas such as Europe and US the incidence rate is low, 0.5–5 cases per 100,000 population per year, whereas in the epidemic region of sub-Saharan Africa rates of up to 1000 cases per 100,000 population per year have been recorded. Twelve different serogroups based on the polysaccharide capsule have been identified, but only six of them (A, B, C, W, X and Y) account for 90% of the IMD globally (). The annual Islamic Hajj pilgrimage to Mecca, Saudi Arabia, has historically been associated with outbreaks of serogroup A. However, during the Hajj pilgrimages of 2000 and 2001, there was an epidemiological shift from serogroup A disease to serogroup W. Serogroup W has previously only been associated with sporadic cases but has emerged as a cause of worldwide outbreaks and continued to cause disease in the sub-Saharan Africa including Niger, South Africa and a large epidemic in Burkina Faso 2002 ().
In this issue of EBioMedicine, investigate the genomic epidemiology of serogroup W ST-11 strains from 1970 to 2013 in order to discriminate sporadic W ST-11 strains from Hajj outbreak strains. Antigen-encoding gene profiles, the presence of recombinant alleles and whole genome phylogenetic analyses compared to the Hajj reference genome (strain ID: ) divided the collection of 270 strains into two clusters: Cluster 1 (Hajj cluster), which consisted of closely related strains collected during, or after the Hajj 2000 epidemic, and Cluster 2 with sporadic strains heterogeneous in nature, consisting of both SB 239063 pre- and post-Hajj ().

In this study we examined the role of ADAM in

In this study, we examined the role of ADAM17 in colitis by developing dextran sulfate sodium (DSS)-induced colitis using two different conditional Adam17-deficient mice, i.e. mice with systemic deletion by the inducible Mx1-Cre gene of Adam17 (Adam17Mx1-Cre+) or those with its deletion in myeloid buy BLZ945 by the lysozyme M promoter (Adam17LysM-Cre+). We also studied the significance of the ADAM17-EGFR pathway in cell proliferation and goblet cell maintenance by utilizing colonic epithelial cell lines, and finally investigated the relevance of our findings to human UC tissues. Our data demonstrate a protective function of epithelial ADAM17 as a gatekeeper molecule against intestinal inflammation.

Materials and Methods


In the present study, we have developed DSS-induced colitis in two different conditional Adam17-deficient mice, and demonstrated that ADAM17 derived from epithelial cells, but not myeloid cells, confers resistance to colitis by driving repair processes through epithelial cell proliferation and goblet cell differentiation. We propose that EGFR activation and its signaling pathways initiated by ADAM17 contribute to the repair of damaged epithelial cells and maintenance of the epithelial barrier in human UC (Supplementary Fig. 6).
Chalaris et al. developed hypomorphic ADAM17 mice (Adam17 mice) that resulted in aggravation of DSS-induced colitis. This study suggested that the impaired phosphorylation of STAT3 via EGFR activation in epithelial cells is implicated for the increased sensitivity to DSS-induced colitis (Chalaris et al., 2010). However, the mice had abnormalities in the eyes, heart and hair follicles during their development, and more importantly, they developed spontaneous inflammation of the skin. Since DSS-induced colitis is known to generate systemic responses in mice (Dong et al., 2013), unexpected responses to DSS due to the innate inflammatory features are likely to be superimposed on top of the colitis induced by this model. Adam17 mice generated by Brandl et al. also showed severe weight loss during DSS administration (Brandl et al., 2010), and the authors demonstrated that ADAM17-mediated EGFR signaling in non-hematopoietic cells plays a protective role against DSS-induced colitis. Although the study provided no information about which cell types in the non-hematopoietic compartment are responsible for the accelerated colitis, we have disclosed that ADAM17 derived from colonic epithelial cells is essential for these processes, and further demonstrated the relevance of the experimental findings to human UC tissues.
Epithelial regeneration is a key process for the recovery from IBDs, and is one of the most significant prognostic factors for long-term remission (Lichtenstein and Rutgeerts, 2010). Epithelial cell proliferation during regeneration is stimulated by several growth factors produced by local epithelial and mesenchymal cells in crypts near the damaged mucosal area. EGFR ligands are one major group of growth factors involved in rapid expansion of crypt epithelial cells, and they are secreted mainly from epithelial cells surrounding the damaged epithelial region (Okamoto and Watanabe, 2005). Previous studies showing that defective EGFR signaling in mice deficient for TGF-α leads to severe inflammation upon DSS challenge (Egger et al., 1997) and overexpression of TGF-α reduces susceptibility of DSS-induced colitis (Egger et al., 1998) have suggested that TGF-α acts as a principal growth factor for protection from colitis. In the present study, TGF-α was overexpressed by the colonic epithelial cells in both DSS-administered control and Adam17Mx1-Cre+ mice, but aggravation of the colitis was observed only in the latter mouse group. The severity of colitis in DSS-treated Adam17Mx1-Cre+ mice was partially rescued by treatment with recombinant TGF-α. Since ADAM17 is the major sheddase for membrane-type TGF-α and its shedding is suppressed in our Adam17Mx1-Cre+ mice (Horiuchi et al., 2007), exacerbation of the colitis in Adam17Mx1-Cre+ mice could be explained by the inability of the colonic epithelia to activate TGF-α.

These findings provide evidence of a possible gene environment

These findings provide evidence of a possible gene-environment correlation (rGE). For example, there may have been greater evolutionary pressure on populations of African ancestry in the past 25,000years, which may have led to selection favoring genetic predisposition to longer telomeres. This may be similar to the selection of individuals with sickle cell or thalassemia trait that occurred over thousands of years in regions of the world with high prevalence of malaria (Kwiatkowski, 2005), a process that has been hypothesized for other disease processes such as 69 8 (Dean et al., 2002). The role of an infectious etiology in the selection process might be a particularly salient hypothesis, as shorter TL has been associated with increased susceptibility to infection (Cohen et al., 2013). TL in this study, however, was measured in salivary samples rather than leukocytes, and it remains unclear how TL measurements in different tissues are associated with overall health and longevity (Friedrich et al., 2000). Alternatively, it may be that TL-associated SNPs are linked with other genes that experienced selection pressure. Another possible explanation is that there may have been founder effects among populations leaving Africa, such that white and other populations had higher frequencies of genes predisposing to shorter TL. Future studies could examine whether black individuals have similar genetic profiles in other countries in which adverse socioeconomic conditions are not as highly correlated with race.
It is also important to note that the PRS is based on SNPs that were obtained in a genome-wide meta-analysis among individuals of European descent (Codd et al., 2013). It may be the case that the genes that determine TL among blacks and other racial groups differ from those among whites, and future research should focus on conducting genome-wide association studies among more diverse samples. While we examined how each GWAS-associated SNP was associated with TL in difference racial/ethnic groups, we were underpowered to detect whether these differences were statistically significant. Nevertheless, several of the SNPs included in the PRS have been associated with TL and disease in non-white populations, suggesting that their influence may span population subgroups (Shen et al., 2011; Du et al., 2015).
We also find that men are more likely to have a lower PRS predictive of longer TL, but no differences in TL by gender. A recent meta-analysis demonstrated that men in fact typically have shorter TL than women, although this finding depends on the type of measurement method performed (Gardner et al., 2014). In our study, none of the TL-associated SNPs were on sex chromosomes, thus suggesting possible environmental rather than genetic explanations for these gender differences. For example, Autoradiography may be a result of men\’s higher mortality rates from a number of chronic and acute conditions related to environmental exposures (Cullen et al., 2015), such that men genetically predisposed to longer TL are more likely to be selected into our sample of older adults.
We also find that older individuals are more likely to have genetic profiles predictive of longer TL. These findings are suggestive of the influence of longer TL on mortality, consistent with prior longitudinal studies and population-based studies demonstrating that longer TL is associated with longer survival (Rehkopf et al., 2013; Bakaysa et al., 2007; Ehrlenbach et al., 2009). While studies in humans have not been able to definitively demonstrate the causal effect of TL on longevity, these findings lend further credence to this hypothesis. Because those who provided genetic samples differ from those who died before being tested, future studies should examine samples that include younger individuals. Recent work has suggested that this bias may be substantial , but currently there are not sample weights available to account for this (Domingue et al., 2016).
Our findings with respect to the factors associated with TL itself are largely consistent with the prior literature, showing that blacks and younger individuals are more likely to have longer telomeres (Adler et al., 2013; Diaz et al., 2010; Hunt et al., 2008; Needham et al., 2013), although some of these associations are attenuated when adjusting for other covariates. The association between being Hispanic and longer TL, however, contradicts some of the prior literature that finds telomeres are shorter or not significantly different than those of whites (Diez roux et al., 2009; Geronimus et al., 2015). It also contradicts our finding that Hispanic individuals have higher PRS values predicting shorter TL; this may be suggestive of survivorship bias in this sub-population or the role of other environmental determinants of TL. For SEP, we find that higher education and greater assets are predictive of shorter telomeres in unadjusted models, contradicting a systematic review that found that higher education is consistently associated with longer TL (Robertson et al., 2013); these findings, however, are no longer statistically significant in adjusted models, suggesting that the associations may be confounded by other sociodemographic factors.

Most importantly we addressed the clinical value of

Most importantly, we addressed the clinical value of the aberrant glycosylation which we observe in AAV patients. Changes in IgG glycosylation, especially galactosylation and sialylation, might be useful to screen patients for their risk of relapse. Our data indicates that analysis of total IgG would be sufficient for this purpose. Already in the first serum sample, acquired a median time of 8months before the time of relapse, we could identify patients that are at risk for a future disease relapse. Differences in the glycosylation profile between relapsing and non-relapsing patients become more pronounced as the time of relapse approaches. Longitudinal acquisition of serum samples taken every few months would reveal changes in the personal glycosylation profile of each patient that could possibly help as a guide when to start treatment in these patients. It remains to be studied, however, whether treatment based on this information will be able to minimize tissue and organ damage.

Authors\’ Contribution

The prevalence of high myopia among the young generation has markedly increased within the last three decades (Morgan et al., 2012; He et al., 2004; Congdon et al., 2008; Wu et al., 2013; Rudnicka et al., 2017). Since high myopia in adults is strongly associated with myopic retinopathy and glaucomatous optic neuropathy, myopia has become one of the leading causes of irreversible visual impairment and blindness (Morgan et al., 2012; Xu et al., 2006, 2007; Chang et al., 2013; Ohno-Matsui et al., 2015). Procedures to prevent development or progression of myopia are needed. Although the influence of lifestyle on the development of myopia in children and teenagers has been demonstrated, the basic mechanisms leading to axial myopia as an overshooting in the process of emmetropization have not yet been fully explained (Jones et al., 2007; Rose et al., 2008; He et al., 2015).
The process of emmetropization describes the AG-14361 cost of the length of the ocular optical axis to the refractive power of the anterior segment including cornea and lens. This process, occurring after the end of the second year of life in humans, mainly involves the sagittal axis of the eye while the horizontal diameter and the vertical diameter elongate by a lower amount (Heine, 1899). Until recently, sclera or choroid were thought to be the primary tissues leading to axial elongation of the eye (Chen et al., 2013; Frost & Norton, 2012; He et al., 2014; Guo et al., 2014; Li et al., 2015; McBrien et al., 2000; Nickla & Wallman, 2010; Siegwart & Strang, 2007; Tao et al., 2013; Wang et al., 2011; Zou et al., 2014). Recent investigations however gave hints that Bruch\’s membrane might be the structure which primarily increased in length and elongated the eye in the process of myopization (Wei et al., 2013; Jonas et al., 2014; Shen et al., 2016; Jonas et al., 2016, 2017a, 2015a,b, 2017b). Reasons for these assumptions were 1) that the choroid got thinner with increasing axial length (if the sclera was the primary elongating tissue, the distance between sclera and Bruch\’s membrane (i.e. thickness of the choroidal space) would become larger) (Wei et al., 2013); 2) that the optical axis ended at the photoreceptor outer segments in close vicinity to the retinal pigment epithelium and Bruch\’s membrane, and not at the sclera, which is separated from the photoreceptor outer segments by the spongy choroid with a physiologically fluctuating thickness of about 250μm; 3) that the volume of the sclera was independent of axial length in individuals with an age of more than two years, so that it was unlikely that an active tissue growth of the sclera was primarily involved in axial elongation (Shen et al., 2016); 4) that retinal thickness and retinal pigment epithelium density in the macular region were independent of axial length (Jonas et al., 2017a); 5) that the length of the macular Bruch\’s membrane in any direction was independent of axial length (Jonas et al., 2015a); and 6) that, subsequently, the axial elongation associated increase in the disc-fovea distance was due to the development and enlargement of parapapillary gamma zone (Jonas et al., 2015b). These findings led to the hypothesis that axial elongation might occur by production of Bruch\’s membrane in the retro-equatorial region leading to a decreased retinal pigment epithelium cell density and retinal thinning in that region and a more tube-like than spherical enlargement of the globe, without compromise in the density of the macular retinal pigment epithelium and in macular retinal thickness (Jonas et al., 2017b).

The objective was to understand the diversity of this organism

The objective was to understand the Paclitaxel cost of this organism across Europe and to get insight into the geographical and temporal evolution of the different genotypes. The diversity of P. jirovecii isolates responsible for PCP across different European countries (n=12) was investigated, in order to detect the most prevalent genotypes and to detect possible transmission within or between centres (n=16) using this novel MLP typing method (Gits-Muselli et al., 2015).

Material and Methods

A total of 361 samples from 361 patients with a median of 25 samples per centre [19–25], obtained from 1998 to 2015 (97.2% collected after 2009), were sent to Saint-Louis Hospital, Paris, France for genotyping. All samples had microscopic evidence of the presence of asci or trophic forms using standard staining or anti-Pneumocystis immunofluorescence, or were PCR-positive with high fungal load according to the local qPCR assay. Of these 361 DNA samples, the six STR markers were correctly amplified in 249 (69.0%) samples from 249 patients (Fig. 2). Samples with amplification failure of one or more of the 6 markers (112/361; 31%) were further excluded. The median number of successfully amplified samples per centre was 17 (11−20). The qPCR assays performed locally on these samples were heterogeneous (mainly in-house PCR targeting either mtLSU, Kex, or MSG genes, including already published assays (Alanio et al., 2011; Larsen et al., 2002; Totet et al., 2003). The median Cq was 25 [22–28]. Male/female ratio was 1.83 and the median age was 55years. The patients\’ predisposing diseases or conditions were AIDS (36.9%), haematological malignancy (19.7%), renal transplantation (13.3%), and other causes of immunosuppression (25.3%), with this piece of information not available for 4.8% of cases.

The present P. jirovecii genotyping study is the first one dealing with several European countries and using an MLP typing (Gits-Muselli et al., 2015). In analysing 249 cases of PCP recruited from 16 centres across 12 European countries, our main findings were the large proportion of PCP cases harbouring mixtures of FIs, the limited genetic evolution of P. jirovecii across Europe, and the possible enrichment of genotypes at some centres, possibly linked to the underlying disease of the patient.
The association between underlying disease/conditions and mixed infection has never been reported. We observed a significant increase of samples containing multiple FIs in HIV patients and a significant decrease of samples containing multiple FIs in renal transplant patients. This could be explained by the evolution of HIV infection over several years with a progressive decrease of about 61CD4T-cells/μL per year (Wolbers et al., 2010), that could allow the HIV-positive patient to inhale numerous and various P. jirovecii genotypes over the course of HIV infection. Then, PCP would occur with a mixture of genotypes encountered by the patient over the last 5–10years. Conversely, renal transplant recipients have a controlled period of immunosuppression, resulting in a shorter duration for exposure to P. jirovecii, during which P. jirovecii would be able to proliferate rapidly, resulting in acute disease (124 to 170days) (Phipps et al., 2011), the starting point potentially being the stop of anti-PCP prophylaxis (de Boer et al., 2011). Similar results were recently reported with a dominant genotype responsible for an outbreak in a haematology ward suggesting a recent acquisition of the epidemic genotype (Robin et al., 2017). Since PCP occurs when prophylaxis is stopped (de Boer et al., 2011), this raises the question of life-long administration of anti-PCP prophylaxis in at-risk patients, especially in renal transplant recipients with prolonged immunodepression (Alanio and Bretagne, 2017; Goto et al., 2017; Wang et al., 2012). However, the fungal load is known to be lower in HIV-negative patients (Alanio et al., 2011; Cordonnier et al., 2016; Roux et al., 2014) than in HIV-positive patients and a low fungal load could negatively influence the detection of mixed infections. Thus, only the most numerous would be evidenced whereas multiple genotypes would be nevertheless present. Using a single nucleotide extension method, which can detect minority alleles until 5–10%, the low fungal loads were not associated with less mixtures than the high fungal loads, suggesting an independent association between number of genotypes with underlying diseases rather than with the fungal load (Alanio et al., 2015). To avoid biases in the interpretation of the results, it was decided not to genotype PCP cases harbouring mixtures of isolates with more than one allele in more than one marker. To interpreted these mixtures, as proposed by other authors (Parobek et al., 2014), would have introduced genotypes which the reality was impossible to ascertain. In addition, in 31% of the samples it was not possible to obtain all makers. This was likely as a result of low DNA fungal loads, degradation of DNA upon storage or shipment, or DNA extraction issues. With these restrictions to the 69% of analysable samples, we found a global prevalence of mixture at 64% (160/249), in the same order of the 70% of mixtures previously reported (Alanio et al., 2016; Gits-Muselli et al., 2015; Hauser et al., 2001; Parobek et al., 2014). However, more sensitive methods such as ultra deep pyrosequencing have detected mixtures in up to 92% of the samples (Alanio et al., 2016). These results suggest, as already described (Hauser et al., 2001; Parobek et al., 2014), that PCP is frequently due to multiple genetically distinct organisms, that are unlikely to be diploid. Indeed, P. jirovecii is known to be a haploid organism (Cissé et al., 2012; Wyder et al., 1998), although lack of detailed genetic analyses prevents the detection of DNA insertion or deletion leading to aneuploidy. However, in the situation where multiple alleles at one locus are observed (n=56), duplication of part of the genome, resulting in aneuploidy, could be responsible for this diversity. Microevolution of part of the P. jirovecii organisms could also explain this phenomenon.
