. In spite of the poor living and working conditions that Syrian refugee children experience, having a close-knit network of family and friends was associated with better health. Interventions that consider social capital dimensions might contribute to improving the health of Syrian refugee children in informal tented settlements (ITSs).Some imprinted genes exhibit parental origin specific expression bias rather than being transcribed exclusively from one copy. The physiological relevance of this remains poorly understood. In an analysis of brain-specific allele-biased expression, we identified that Trappc9, a cellular trafficking factor, was expressed predominantly (~70%) from the maternally inherited allele. Loss-of-function mutations in human TRAPPC9 cause a rare neurodevelopmental syndrome characterized by microcephaly and obesity. By studying Trappc9 null mice we discovered that homozygous mutant mice showed a reduction in brain size, exploratory activity and social memory, as well as a marked increase in body weight. A role for Trappc9 in energy balance was further supported by increased ad libitum food intake in a child with TRAPPC9 deficiency. Strikingly, heterozygous mice lacking the maternal allele (70% reduced expression) had pathology similar to homozygous mutants, whereas mice lacking the paternal allele (30% reduction) were phenotypically normal. Taken together, we conclude that Trappc9 deficient mice recapitulate key pathological features of TRAPPC9 mutations in humans and identify a role for Trappc9 and its imprinting in controlling brain development and metabolism.Tubulin dimers associate longitudinally and laterally to form metastable microtubules (MTs). MT disassembly is preceded by subtle structural changes in tubulin fueled by GTP hydrolysis. These changes render the MT lattice unstable, but it is unclear exactly how they affect lattice energetics and strain. We performed long-time atomistic simulations to interrogate the impacts of GTP hydrolysis on tubulin lattice conformation, lateral inter-dimer interactions, and (non-)local lateral coordination of dimer motions. The simulations suggest that most of the hydrolysis energy is stored in the lattice in the form of longitudinal strain. While not significantly affecting lateral bond stability, the stored elastic energy results in more strongly confined and correlated dynamics of GDP-tubulins, thereby entropically destabilizing the MT lattice.The transmission of trachoma, caused by repeat infections with Chlamydia trachomatis, and many enteropathogens are linked to water quantity. We hypothesized that children living further from a water source would have higher exposure to C. trachomatis and enteric pathogens as determined by antibody responses. We used a multiplex bead assay to measure IgG antibody responses to C. trachomatis, Giardia intestinalis, Cryptosporidium parvum, Entamoeba histolytica, Salmonella enterica, Campylobacter jejuni, enterotoxigenic Escherichia coli (ETEC) and Vibrio cholerae in eluted dried blood spots collected from 2267 children ages 0-9 years in 40 communities in rural Ethiopia in 2016. Linear distance from the child's house to the nearest water source was calculated. We derived seroprevalence cutoffs using external negative control populations, if available, or by fitting finite mixture models. We used targeted maximum likelihood estimation to estimate differences in seroprevalence according to distance to the nearest water source. Seroprevalence among 1-9-year-olds was 43% for C. trachomatis, 28% for S. enterica, 70% for E. histolytica, 54% for G. intestinalis, 96% for C. jejuni, 76% for ETEC and 94% for C. parvum. Seroprevalence increased with age for all pathogens. Median distance to the nearest water source was 473 meters (IQR 268, 719). Children living furthest from a water source had a 12% (95% CI 2.6, 21.6) higher seroprevalence of S. enterica and a 12.7% (95% CI 2.9, 22.6) higher seroprevalence of G. intestinalis compared to children living nearest. Seroprevalence for C. trachomatis and enteropathogens was high, with marked increases for most enteropathogens in the first two years of life. Children living further from a water source had higher seroprevalence of S. enterica and G. intestinalis indicating that improving access to water in the Ethiopia's Amhara region may reduce exposure to these enteropathogens in young children.The development of a vaccine, particularly one that can help against the recent pandemic, is a topic that has recently attracted public opinion. More than ninety vaccines are currently being developed against Sars-Cov2 by universities and companies around the world. They are protein-based vaccines, viral vector vaccines, DNA or RNA vaccines and inactivated or attenuated viral vaccines. The development of a vaccine starts from the identification and characterization of the microorganism that causes the disease. The second step is the preclinical phase. Then, there is the phase of clinical experimentation, which allows to study the posology, efficacy and safety of the vaccine, on an increasingly larger sample. Gefitinib nmr In the European Union, vaccines are authorized through two procedures (EU and national) based on the quality, safety and efficacy requirements defined by the European and international guidelines. Timing of realization, authorization and marketing of new vaccines can be shortened in cases of particular need, through an accelerated evaluation known as "Priority Medicines". In this period, it is crucial not to neglect current vaccinations. In fact, during the pandemic period, many countries postponed vaccination campaigns against many vaccine-preventable diseases, causing a marked decrease in routine immunizations in childhood.The Authors present the results of an experience carried out in a University General Hospital, for the assessment of the sanitation of surfaces and instruments in the context of hospital refection. A specific procedure has been quarterly implemented in order to verify the correct execution of the sanitization procedures. In the time-period September 2016 - March 2020 Petri dishes and tampons were used in order to determine the following microbiological parameters and indicators total bacterial load at 30 degrees C, Coliforms, Listeria monocytogenes, Salmonella spp, Staphylococcus aureus, Escherichia coli and mycetic load. Only 7 out of 82 sanitized surfaces (8.5% of the total) were found to be not complying, only for total bacterial load at 30 degrees C, mycetic load and Coliforms. The systematic application of this procedure and the results of the survey conducted, comforting as a whole, confirm the attention reserved to the hygienic level of surfaces, tools, equipment and utensils, in the context of the centralized catering service of the hospital, in which the Health Department, sharing with the UOC Hospital Hygiene the specific hygienic procedure, has always been at the forefront of the proposal of interventions, considering the increased susceptibility and vulnerability of the hospitalized patients.
