Objective Administered in a timely manner, current evidence-based interventions could reduce neonatal deaths from infections, intrapartum injuries and complications due to prematurity. The three delays model (delay in seeking care, in arriving at a health facility, and in receiving adequate care), which has been applied to understanding maternal deaths, may be useful for understanding neonatal deaths. We assess the main causes of neonatal deaths in Rwanda and their associated delays. Methods Using a cross-sectional study design, we evaluated data from 2012 from 40 facilities in which babies were delivered...

BACKGROUND: Extra-oral bitter taste receptors have been associated with innate bacterial defence mechanisms. Genetic variation in T2R38 functionality has been shown to be associated with susceptibility to upper respiratory tract infections and chronic rhinosinusitis (CRS). We sought to independently assess the influence of bitter taste receptor genotype on the presence of culturable bacteria in the sinuses. METHODOLOGY: A cross-sectional analysis of patients with CRS undergoing surgery was performed...

BACKGROUND: Bile acids (BAs) are steroid molecules that are synthesized in the liver. In addition to their important role as a surfactant in solubilizing lipids and promoting the absorption of lipids in the gastrointestinal tract, they act as inflammagens. The role of BAs and their receptor farnesoid X receptor (FXR) during viral infection has not been studied in detail. METHODS: By using FXR-deficient mice, we investigated the role of bile acid receptor FXR during infection with lymphocytic choriomeningitis virus (LCMV)...

REVIEW
Alethia Villasenor, Didier Y R Stainier
The hepatopancreatic ductal system is the collection of ducts that connect the liver and pancreas to the digestive tract. The formation of this system is necessary for the transport of exocrine secretions, for the correct assembly of the pancreatobiliary ductal system, and for the overall function of the digestive system. Studies on endoderm organ formation have significantly advanced our understanding of the molecular mechanisms that govern organ induction, organ specification and morphogenesis of the major foregut-derived organs...

In contact sports, repetitive concussive brain injury (rCBI) is the prevalent form of head injury seen in athletes. The need for effective treatment is urgent as rCBI has been associated with a host of cognitive, behavioral and neurological complaints. There has been a growing trend in the use of female animals in pre-clinical research, but few studies have investigated possible sex differences following rCBI. The goal of the current study was to determine any differences between male and female C57BL/6J mice on assessments of learning and memory after repetitive concussive injury...

Pectus excavatum is one of the most common congenital chest wall deformities. The degree of sternal depression, which may result in compression of the right heart by the chest wall, is variable. While typically asymptomatic, there are various symptoms that can result from severe pectus excavatum. We report on a patient with severe pectus excavatum leading to dynamic obstruction of the right ventricular outflow tract in the seated position.

Recently, we published a first anatomical Diffusion Tensor Imaging (DTI) atlas regarding white matter tracts in the canine brain. The purpose of this study was to show the significance of DTI in the revelation of the white matter fibres in the feline brain (i.e. to obtain an anatomical DTI atlas of images) and to descriptively compare these to previously obtained white matter fibre images of the canine brain. DTI MR Images of 4 cats euthanised for reasons other than neurological disorders were obtained with a 3 T system...

Escherichia coli clones ST131, ST69, ST95, and ST73 are frequent causes of urinary tract infections (UTI) and bloodstream infections. Specific clones and virulence profiles of E. coli causing UTI in men has been rarely described. The aim of this study was to characterize patient and clonal characteristics of community-acquired UTI caused by E. coli in men (n=12) and women (n=127) in Rio de Janeiro, Brazil, complementing a previous work. We characterized isolates in phylogenetic groups, ERIC2-PCR and PFGE types, MLST, genome similarity and virulence gene-profiles...

Hepatocyte growth factor (HGF) and MET are candidates of targeted therapies for cancer patients. Although MET and HGF are commonly expressed in biliary tract cancers, their expression and gene copy number status and their association with KRAS mutations have not been investigated in pancreatobiliary-type ampullary adenocarcinomas (A-ACs), one of the aggressive periampullary cancers. MET and HGF expressions and MET copy number status were examined by performing immunohistochemistry (IHC) and silver in situ hybridization (SISH) in 62 surgically resected, paraffin-embedded tumors, respectively...

REVIEW
Alexander R Moschen, Timon E Adolph, Romana R Gerner, Verena Wieser, Herbert Tilg
Lipocalin-2 (LCN2), also known as neutrophil gelatinase-associated lipocalin (NGAL), is released by various cell types and is an attractive biomarker of inflammation, ischemia, infection, and kidney damage. Both intestinal and metabolic inflammation, as observed in obesity and related disorders, are associated with increased LCN2 synthesis. While LCN2 in the intestinal tract regulates the composition of the gut microbiota and shows anti-inflammatory activities, it also exhibits proinflammatory activities in other experimental settings...

BACKGROUND: Researchers have found that semi-occluded vocal tract (SOVT) exercises may increase vocal economy by reducing phonation threshold pressure and effort while increasing or maintaining consistent acoustic output. This research has focused solely on individual singers. Much singing instruction, however, takes place in choral settings. Choral singers may use different resonance strategies or unconsciously adjust their singing based on the ability to hear their own sound in relation to others...

Rhinovirus (RV) is a common respiratory viral infection linked to worsening of chronic respiratory diseases including cystic fibrosis (CF) and asthma. RV was tested by RT-PCR in samples (n = 465) collected from the upper (nasal swab, oropharyngeal suction and sputum) and lower (bronchoalveolar washings) respiratory tract of 110 children with CF. Air samples (n = 52) collected from the operating theatres and outpatient clinics were tested for RV. RV was found in 43% of children <5 years suffering an exacerbation, and 12% of older children (5-17 years)...

Thomas J Giardina, Andrew G Clark, Anthony C Fiumera
Female Drosophila melanogaster frequently mate with multiple males in nature as shown through parentage analysis. Although polyandry is well documented, we know little about the timing between mating events in wild Drosophila populations due to the challenge of following behaviors of individual females. In this study we used the presence of a male reproductive protein that is transferred to the female during mating (Sex Peptide, SP) to determine whether she had recently mated. We sampled females throughout the day, conducted control matings to determine the decay rate of SP within the female reproductive tract and performed computer simulations to fit the observed proportion of mated females to a non-homogenous Poisson process that defined the expected time between successive matings for a given female...

Cas Eikenaar
To support migratory endurance flight, birds accumulate large amounts of fat by hyperphagia (fueling). Whereas the factors influencing migrants' motivation to fuel are well described, the physiological mechanism regulating fueling is largely unknown. Hormones are likely involved and arguably the best studied with respect to food intake and fueling is corticosterone. Corticosterone has a permissive effect, as blocking the hormone's actions prohibits efficient fueling. There are no indications, though that corticosterone stimulates fueling, and some studies even observed negative correlations between corticosterone level and food intake and speed of fueling...

An 82-year-old woman who had been suffering from repeated obstructive jaundice for 7 years was referred to our hospital. Although endoscopic aspiration of the mucin in the common bile duct had been temporally effective, origin of the mucin production had not been detectable. The patient thus had been forced to be on long-term follow-up without curative resection. Endoscopic retrograde cholangioscopy on admission revealed massive mucin in the common bile duct. In addition, an anomalous bile duct located proximal to the gallbladder was identified...

Reactive oxygen species (ROS) is a novel therapeutic strategy for topical or local application to wounds, mucosa or internal structures where there may be heavy bacterial bioburden with biofilm and chronic inflammation. Bacterial biofilms are a significant problem in clinical settings owing to their increased tolerance towards conventionally prescribed antibiotics and their propensity for selection of further antibacterial resistance. There is therefore a pressing need for the development of alternative therapeutic strategies that can improve antibiotic efficacy towards biofilms...

Qing-Hua Granule (QHG), the modified formulation of a classical Chinese prescription named Gegen Qinlian Decoction, was clinically employed to treat type 2 diabetes mellitus (T2DM) through regulation of glucagon-like peptide-1 (GLP-1). However, the potential mechanism is unknown. We investigate whether QHG induces GLP-1 secretion via activation of bitter taste receptor (TAS2R) pathway in the gastrointestinal tract of db/db mice. The db/db mice were intragastrically (i.g.) administered QHG (low/medium/high dose) once daily for 8 weeks...

BACKGROUND: Intraoperative electrophysiology is increasingly used for various lesion resections, both in adult and pediatric brain surgery. Subcortical mapping is often used in adult surgery when lesions lie in proximity to the corticospinal tract (CST). We describe a novel technique of continuous subcortical mapping using an electrified Cavitron UltraSonic Aspirator (CUSA) in children with supratentorial lesions. METHODS: We evaluated the method of subcortical mapping using a CUSA as a stimulation probe...
