A survey-based analysis of the academic job market

Many postdoctoral researchers apply for faculty positions knowing relatively little about the hiring process or what is needed to secure a job offer. To address this lack of knowledge about the hiring process we conducted a survey of applicants for faculty positions: the survey ran between May 2018 and May 2019, and received 317 responses. We analyzed the responses to explore the interplay between various scholarly metrics and hiring outcomes. We concluded that, above a certain threshold, the benchmarks traditionally used to measure research success - including funding, number of publications or journals published in - were unable to completely differentiate applicants with and without job offers. Respondents also reported that the hiring process was unnecessarily stressful, time-consuming, and lacking in feedback, irrespective of outcome. Our findings suggest that there is considerable scope to improve the transparency of the hiring process

Genomic and Epigenomic Responses to Chronic Stress Involve miRNA-Mediated Programming

Stress represents a critical influence on motor system function and has been shown to impair movement performance. We hypothesized that stress-induced motor impairments are due to brain-specific changes in miRNA and protein-encoding gene expression. Here we show a causal link between stress-induced motor impairment and associated genetic and epigenetic responses in relevant central motor areas in a rat model. Exposure to two weeks of mild restraint stress altered the expression of 39 genes and nine miRNAs in the cerebellum. In line with persistent behavioural impairments, some changes in gene and miRNA expression were resistant to recovery from stress. Interestingly, stress up-regulated the expression of Adipoq and prolactin receptor mRNAs in the cerebellum. Stress also altered the expression of Prlr, miR-186, and miR-709 in hippocampus and prefrontal cortex. In addition, our findings demonstrate that miR-186 targets the gene Eps15. Furthermore, we found an age-dependent increase in EphrinB3 and GabaA4 receptors. These data show that even mild stress results in substantial genomic and epigenomic changes involving miRNA expression and associated gene targets in the motor system. These findings suggest a central role of miRNA-regulated gene expression in the stress response and in associated neurological function

Impact of Maternal Folate Deficiencies on Early Neurological Development: A Narrative Review

Context Folates are B-vitamins that cannot be generated de novo and are therefore obtained from the diet. In the brain, these vitamins are involved in nucleotide synthesis, DNA repair, lipid metabolism, methylation and neurotransmitter synthesis. It is well established that adequate levels of maternal folates are required for closure of the neural tube within the first month of pregnancy, however, it is not clear whether maternal folates are needed throughout pregnancy for brain development and whether they influence offspring neurological function after birth. The aim of this review is to outline current literature from epidemiological and animal model studies that shows maternal supplementation of folates throughout pregnancy does indeed affect offspring neurological function after birth. Evidence Acquisition A Medline search was performed using the following mesh terms, maternal-fetal exchange, folic acid, offspring neurologic manifestations, methylenetetrahydrofolate reductase (MTHFR), embryology, and behavior. Results The studies described in the present review have reported that maternal deficiencies in folates during pregnancy result in changes in behavior as well as in blood and brain tissue in offspring, including altered methylation, including reduced levels of the global methyl donor S-adenosylmethionine (SAM), and increased levels of oxidative stress. Conclusions The data summarized here outlines the importance of adequate levels of folates throughout pregnancy to facilitate appropriate neurological development of offspring after birth

Use of ganciclovir in the treatment of acquired cytomegalovirus disease in a preterm infant

The first use of ganciclovir in a preterm infant is reported. The 27 week appropriate-for-gestational-age male infant developed a disseminated cytomegalovirus infection subsequent to a blood transfusion. A daily dose of 10 mg/kg administered intravenously in two divided doses for a total of 14 days was given without adverse clinical or toxic effects. The patient has remained well following discharge from hospital
