The neurodevelopment and functioning of the central nervous system, and especially the cerebral cortex, have basic importance to understand neuropsychiatric disorders like autism. Fibroblast growth factor-2 (FGF-2) plays a very important role in the development and functioning of the cortex. FGF-2 is related to developmental processes in the central nervous system such as neurogenesis, migration, differentiation and survival. This study researched the serum FGF-2 levels in children with autism spectrum disorder (ASD)...

The incidence of HPV-related oropharyngeal squamous cell carcinoma (OPSCC) has increased more than 200% in the past 20 years. Recent genetic sequencing efforts have elucidated relevant genes in head and neck cancer, but HPV-related tumors have consistently shown few DNA mutations. In this study, we sought to analyze alternative splicing events (ASE) that could alter gene function independent of mutations. To identify ASE unique to HPV-related tumors, RNA sequencing was performed on 46 HPV-positive OPSCC and 25 normal tissue samples...

The ever increasing pace of development of novel therapies mandates efficient methodologies for assessment of their tolerability and activity. Evidence increasingly support the merits of model-based dose-finding designs in identifying the recommended Phase II dose compared to conventional rule-based designs such as the 3+3 but despite this, their use remains limited. Here, we propose a useful tool, Dose Transition Pathways (DTP), which helps overcome several commonly-faced practical and methodological challenges in the implementation of model-based designs...

PROBLEM: Workplace violence, incidents against people in their workplaces, is a growing problem in Australia causing untold personal suffering as well as costing Australian businesses in productivity. Midwives have been highlighted as a group particularly at risk, yet in Australia there is little research into workplace violence against midwives and even less into midwifery students. AIM: This study aimed to explore Australian midwifery students' responses to workplace violence as well as to gauge the impact of workplace violence on them...

If species' evolutionary pasts predetermine their responses to evolutionarily novel stressors, then phylogeny could predict species survival in an increasingly human-dominated world. To understand the role of phylogenetic relatedness in structuring responses to rapid environmental change, we focused on assemblages of Neotropical bats, an ecologically diverse and functionally important group. We examined how taxonomic and phylogenetic diversity shift between tropical forest and farmland. We then explored the importance of evolutionary history by ascertaining whether close relatives share similar responses to environmental change and which species traits might mediate these trends...

OBJECTIVE: The discovery of specific microRNAs (miRNA) mediates a better understanding of molecular mechanisms, diagnosis and prognosis of complex phenotypes. Synthesis of the RhD blood group involves multiple factors causing variation in the expression of RHD antigens. The mechanism underlying the extremely weak expression of RHD antigen associated with the RHD variant called DEL (D-elute) is incompletely understood. Down-regulation of gene expression through miRNA is a guide to the potential involvement of miRNAs in the DEL blood group...

A combination of high-throughput, multiplexed, quantitative methods with computational modeling and statistical approaches is required to obtain system-level understanding of biological function. Mass spectrometry (MS)-based proteomics has emerged as a preferred tool for the analysis of changes in protein abundance and their post-translational modification (PTM) levels at a global scale, comparable with genomic experiments and generating data suitable for use in mathematical modeling of signaling pathways. Here we describe a set of parallel bottom-up proteomic approaches to detect and quantify the global protein changes in total intracellular proteins, their phosphorylation, and the proteins released by active and passive secretion or shedding mechanisms (referred to as the secretome as reviewed in Makridakis and Vlahou, J Proteome 73:2291-2305, 2010) in response to the stimulation of Toll-like receptors (TLRs) with specific ligands in cultured macrophages...

INTRODUCTION: Understanding the neural basis underlying major depressive disorder (MDD) is essential for the diagnosis and treatment of this mental disorder. Aberrant activation and functional connectivity of the default mode network (DMN) have been consistently found in patients with MDD. It is not known whether effective connectivity within the DMN is altered in MDD. OBJECTS: The primary object of this study is to investigate the effective connectivity within the DMN during resting state in MDD patients before and after eight weeks of antidepressant treatment...

Several catalysis, cellular regulation, immune function, cell wall assembly, transport, signaling and inhibition occur through Protein- Protein Interactions (PPI). This is possible with the formation of specific yet stable protein-protein interfaces. Therefore, it is of interest to understand its molecular principles using structural data in relation to known function. Several interface features have been documented using known X-ray structures of protein complexes since 1975. This has improved our understanding of the interface using structural features such as interface area, binding energy, hydrophobicity, relative hydrophobicity, salt bridges and hydrogen bonds...

REVIEW
Georgina Krebs, Lorena Fernández de la Cruz, David Mataix-Cols
Body dysmorphic disorder (BDD) is a relatively common and disabling psychiatric disorder characterised by excessive and persistent preoccupation with perceived defects or flaws in one's appearance, which are unnoticeable to others, and associated repetitive behaviours (eg, mirror checking). The disorder generally starts in adolescence, but often goes unnoticed and is severely underdiagnosed. Left untreated, BDD typically persists and causes marked functional impairment in multiple domains. This clinical review considers recent advances in the epidemiology and classification of BDD, including its reclassification in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders under the new 'Obsessive-Compulsive and Related Disorders' chapter...

BACKGROUND: The extended illness-death model is a useful tool to study the risks and consequences of hospital-acquired infections (HAIs). The statistical quantities of interest are the transition-specific hazard rates and the transition probabilities as well as attributable mortality (AM) and the population-attributable fraction (PAF). In the most general case calculation of these expressions is mathematically complex. METHODS: When assuming time-constant hazards calculation of the quantities of interest is facilitated...

Studying cell behavior within 3D material niches is key to understanding cell biology in health and diseases, and developing biomaterials for regenerative medicine applications. Current approaches to studying these cell-material niches have low throughput and can only analyze a few replicates per experiment resulting in reduced measurement assurance and analytical power. Here, we report 3D material cytometry (3DMaC), a novel high-throughput method based on microfabricated, shape-specific 3D cell-material niches and imaging cytometry...
