Radical cystoprostatectomy (RCP) followed by bilateral pelvic lymphadenectomy and urinary diversion remains the gold-standard therapy for men with localized muscle-invasive bladder cancer (MIBC). Prostate cancer might be incidentally detected at the time of RCP with a reported prevalence of 24-51%. Typically, these patients are considered to have clinically insignificant disease, but data from emerging series challenge this assumption and suggest that some of these tumours might be aggressive, or somehow increase the aggressiveness of the associated MIBC, and can negatively influence the patient's overall survival outcomes...

Global stressors, such as ocean acidification, constitute a rapidly emerging and significant problem for marine organisms, ecosystem functioning and services. The coastal ecosystems of the Humboldt Current System (HCS) off Chile harbour a broad physical-chemical latitudinal and temporal gradient with considerable patchiness in local oceanographic conditions. This heterogeneity may, in turn, modulate the specific tolerances of organisms to climate stress in species with populations distributed along this environmental gradient...

INTRODUCTION: Energy drinks (EDs) have become an integral part of the young adult, athletic, and military culture. Many athletes are convinced that EDs enhance performance, and service members as well as college students frequently use EDs as stimulants to counter sleep deprivation, or to improve academic performance. However, concerns have been raised by some military leaders about potential adverse effects of EDs. MATERIALS AND METHODS: A needs assessment survey of a convenience sample of military health care providers was conducted and identified EDs as a top knowledge need for those providers working in the area of traumatic brain injury (TBI)...

The detection of specific RNA molecules in embryonic tissues has wide research applications including studying gene expression dynamics in brain development and evolution. Recent advances in sequencing technologies have introduced new animal models to explore the molecular principles underlying the assembly and diversification of brain circuits between different amniote species. Here, we provide a step-by-step protocol for a versatile in situ hybridization method that is immediately applicable to a range of amniote embryos including zebra finch and Madagascar ground gecko, two new model organisms that have rapidly emerged for comparative brain studies over recent years...

The study of protein-protein interactions represents a key aspect of biological research. Identifying unknown protein binding partners using mass spectrometry (MS)-based proteomics has evolved into an indispensable strategy in drug discovery. The classic approach of immunoprecipitation with specific antibodies against the proteins of interest has limitations, such as the need for immunoprecipitation-qualified antibody. The biotin AP-tag pull-down system has the advantage of high specificity, ease of use, and no requirement for antibody...

The functional interactions of carbohydrates and their protein receptors are the basis of biological events critical to the evolution of pathological states. Hence, for the past years, such interactions have become the focus of research for the development of therapeutics and discovery of novel glycan biomarkers based on their binding affinity. Due to the high sensitivity, throughput, reproducibility, and capability to ionize minor species in heterogeneous mixtures, microfluidics-mass spectrometry (MS) has recently emerged as a method of choice in protein-glycan interactomics...

BACKGROUND: Incidental findings on neuroimaging in the pediatric population are an emerging treatment challenge. Treatment options for these incidental childhood brain mass lesions, which radiologically may be assumed to be low-grade gliomas (LGG), vary, ranging from careful conservative "wait and scan" treatment to surgical biopsy, gross total resection, and upfront radiation and/or chemotherapy. As malignant transformation of LGG in children is extremely rare, some series advocate careful conservative management of these lesions; however, universal treatment protocols are not totally agreed upon...

BACKGROUND: Antipsychotic prescribing is prevalent in nursing homes for the management of behavioral and psychological symptoms of dementia (BPSD), despite the known risks and limited effectiveness. Many studies have attempted to understand this continuing phenomenon, using qualitative research methods, and have generated varied and sometimes conflicting findings. To date, the totality of this qualitative evidence has not been systematically collated and synthesized. AIMS: To synthesize the findings from individual qualitative studies on decision-making and prescribing behaviors for antipsychotics in nursing home residents with dementia, with a view to informing intervention development and quality improvement in this field...

BACKGROUND: Institutional protocols for preincisional antibiotic prophylaxis can standardize care and improve outcomes. However, challenges remain in compliance with such protocols for urgent or emergent operations. We hypothesized that compliance with an institutional protocol for antibiotic prophylaxis for appendectomy for appendicitis in pediatric patients results in reduced surgical site infections (SSIs) after simple appendectomy. METHODS: This retrospective study assessed all pediatric patients (≤18 y) who underwent appendectomy for confirmed simple appendicitis at a tertiary children's hospital between 2012 and 2015...

PURPOSE OF REVIEW: In the last decade, with the advances of optical coherence tomography (OCT) technology, different imaging protocols and analysis algorithms have been introduced to maximize the potential of this diagnostic tool in the evaluation of different eye diseases. This review aims to provide an update on these additional features, with respect to the management of a diverse range of neuro-ophthalmologic conditions. RECENT FINDINGS: Macular ganglion cell complex (mGCC) analysis has been shown to be superior to peripapillary retinal nerve fiber layer (pRNFL) analysis in certain settings, such as differentiating Leber's hereditary optic neuropathy from functional visual loss; monitoring neurodegenerative diseases or multiple sclerosis; and predicting visual loss in nonarteritic ischemic optic neuropathy...

Aptamers are high affinity single-stranded DNA/RNA molecules, produced by a combinatorial procedure named SELEX (Systematic Evolution of Ligands by Exponential enrichment), that are emerging as promising diagnostic and therapeutic tools. Among selection strategies, procedures using living cells as complex targets (referred as "cell-SELEX") have been developed as an effective mean to generate aptamers for heavily modified cell surface proteins, assuring the binding of the target in its native conformation. Here we give an up-to-date overview on cell-SELEX technology, discussing the most recent advances with a particular focus on cancer cell targeting...

Hydrogels have emerged as a highly interdisciplinary topic as they play a significant role for a vast number of applications. They have been studied extensively as materials for contact lenses, wound dressing and as filler material in soft-tissue augmentation, in which classical polymer backbones such as hydroxyethylmethacrylate (HEMA) are typically employed. More recently, polysaccharides have received attention, particularly in the fields of regenerative medicine and tissue engineering, as ideal candidate materials for artificial extracellular matrices (ECM)...

BACKGROUND: Various explanations account for suicide incidents, and some patients continue to attempt afterwards and others never again. The suicide mortality rate increases with the number of serious attempts. The prevention of secondary attempt of suicide should be an important approach to reduce suicide mortality. However, the characteristics of the targeted population of repeated suicide attempters are understudied. METHODS: This was a cross-sectional data collection from hospital emergency room from patients who had either attempted suicide for the first time (n=721) or for two or more times (n=70)...

BACKGROUND: A wide range of neuroimaging and neuromodulation studies have shown that the dorsolateral prefrontal cortex (DLPFC) plays a pivotal role in decision-making. Of particular interest is the question of its role in decision-making when conditions are uncertain and whether manipulating this neural substrate through neuromodulation changes subsequent risk-taking behaviour. Previous work using the Balloon Analogue Risk Task (BART) suggests that bilateral tDCS stimulation of the DLPFC reduces risk-taking behaviour but unilateral stimulation has no effect...
