It is estimated that over a billion people are infected with soil-transmitted helminths (STHs) globally with majority occurring in tropical and subtropical regions of the world. The roundworm (Ascaris lumbricoides), whipworm (Trichuris trichiura), and hookworms (Anclostoma duodenale and Necator americanus) are the main species infecting people. These infections are mostly gained through exposure to faecally contaminated water, soil or contaminated food and with an increase in the risk of infections due to wastewater and sludge reuse in agriculture...

INTRODUCTION: Gastro-oesophageal reflux disease (GORD) has been implicated in the development of chronic rhinosinusitis (CRS). The association of GORD with CRS is systematically assessed from the medical literature. METHODOLOGY: Embase and MEDLINE were searched using a comprehensive strategy limited to English language and Human subjects. Any study with original data on the experimental, diagnostic, treatment or prognostic association of CRS with GORD was included...

INTRODUCTION: The value of imaging the deep branch of the ulnar nerve (DBUN) over its entire course has not been clarified. Therefore, this study aimed to evaluate the feasibility of visualizing the DBUN from its origin to the most distal point. METHODS: We performed high-resolution ultrasound (HRUS) with high-frequency probes (18-22MhZ), HRUS-guided ink-marking, and consecutive dissection in 8 fresh cadaver hands. In both hands of 10 healthy volunteers (n=20), the cross-sectional area (CSA) was measured at 2 different locations (R1+R2)...

Laryngo-onycho-cutaneous syndrome (LOC) is a rare autosomal recessive genodermatosis that has been mainly described in the offspring of consanguineous families with origin in the Punjabi region of Pakistan and India [1]. Founder mutations affecting the LAMA3A gene on chromosome 18q11.2 have been implicated to underlie this syndrome [1,2]. Based on its molecular and clinical features, LOC was recently classified as a subtype of junctional Epidermolysis bullosa (JEB) [1]. This article is protected by copyright...

Rachel Kahn Best
In the past fifty years, disease advocacy organizations have multiplied and gained political influence, but they have often been reluctant to ask the government to intervene in health care provision. This article asks why. Using original quantitative and qualitative data on the goals and political claims of over one thousand organizations from 1960 through 2014, I find that many early disease advocacy organizations prioritized health care access. But unfavorable political climates discouraged new organizations from focusing on access to treatment...

OBJECTIVE: The absence of a gold standard for scleroderma renal crisis (SRC) has hindered our understanding of this problem. The objective of this scoping review was to identify the criteria used to define SRC in order to guide the development of a consensus definition for SRC. METHODS: We conducted a search in three databases: Medline, Embase and non-Ovid Pubmed. Papers were eligible for inclusion if they were full-length articles in English whose main topic was SRC or scleroderma renal disease...

Baobab seed oil contains specific fatty acids. Most of the studies on baobab fatty acids have been carried out singly and in isolation from each other, making it difficult to compare results through different species. The objective of the present study is to establish the seed fatty acid composition of each Adansonia species in order to evaluate and understand the relationships between the oil chemical compositions, the baobabs' taxonomy and, the ecological and geographical origin of each seed lot. The seed oils have been analysed using gas chromatography (GC)...

Many statistical methods have recently been developed for identifying subgroups of patients who may benefit from different available treatments. Compared with the traditional outcome-modeling approaches, these methods focus on modeling interactions between the treatments and covariates while by-pass or minimize modeling the main effects of covariates because the subgroup identification only depends on the sign of the interaction. However, these methods are scattered and often narrow in scope. In this article, we propose a general framework, by weighting and A-learning, for subgroup identification in both randomized clinical trials and observational studies...

Gambierdiscus, a benthic dinoflagellate, produces ciguatoxins that cause the human illness Ciguatera. Ciguatoxins are polyether ladder compounds that have a polyketide origin, indicating that polyketide synthases (PKS) are involved in their production. We sequenced transcriptomes of G. excentricus and G. polynesiensis and found 264 contigs encoding single domain ketoacyl synthases (KS; G. excentricus: 106, G. polynesiensis: 143) and ketoreductases (KR; G. excentricus: 7, G. polynesiensis: 8) with sequence similarity to type I PKSs, as reported in other dinoflagellates...

Just before the onset of hearing, the inner hair cells (IHCs) receive inhibitory efferent input from cholinergic medial olivocochlear (MOC) neurons originating in the brainstem. This input may serve a role in the maturation of the ascending (afferent) auditory system by inhibiting spontaneous activity of the IHCs. To investigate the molecular mechanisms regulating these IHC efferent synapses, we combined electrical stimulation of the efferent fibres with patch clamp recordings from the IHCs to measure efferent synaptic strength...

Prostate cancer is the second most commonly diagnosed male cancer in the world. The molecular mechanisms underlying its development and progression are still unclear. Here we show analysis of a prostate cancer RNA-sequencing dataset that was originally generated by Ren et al. [3] from the prostate tumor and adjacent normal tissues of 14 patients. The data presented here was analyzed using our RNA-sequencing bioinformatics analysis pipeline implemented on the bioinformatics web platform, Galaxy. The relative expression of fibronectin (FN1) and the androgen receptor (AR) were calculated in fragments per kilobase of transcript per million mapped reads, and represented in FPKM unit...

Prorocentrum mexicanum and P. rhathymum are toxicologically important dinoflagellates, but their relationship is not well defined. We investigated strains from Puerto Rico and Brazil by light and scanning electron microscopies. We provide molecular data from a strain isolated near the type locality of P. rhathymum, and the first morphological and molecular data from the South Atlantic Ocean. The rRNA gene (rDNA) sequences of the Puerto Rican and Brazilian strains were identical, and their morphologies fit the description of P...

Post-transcriptional gene silencing (PTGS) is a defense mechanism that targets invading nucleic acids from endogenous (transposons) or exogenous (pathogens, transgenes) origins. Genetic screens based on the reactivation of silenced transgenes have long been used to identify cellular PTGS components and regulators. Here we show that the first isolated PTGS-deficient mutant, sgs1, is impaired in the transcription factor NAC52. This mutant exhibits striking similarities with a mutant impaired in the H3K4me3 demethylase JMJ14 isolated from the same genetic screen...

In 2016, the British Journal of Biomedical Science published 36 reports outlining specific advances in each of the various disciplines within biomedical science. These were one review, 25 original articles, 9 'In Brief' reports and one letter to the Editor. Of these, the majority were in blood science (5 in biochemistry, 7 in haematology and 2 in immunology) and infection science (8 in microbiology, 2 in virology) with a smaller number in cellular sciences (6 in cellular pathology and 2 in cytopathology). Three reports considered both biochemistry and immunology, while another reported an advance in the identification of chromosomal abnormalities...

PURPOSE: Recent pulmonary imaging research has revealed that in patients with chronic obstructive pulmonary disease (COPD) and asthma, structural and functional abnormalities are spatially heterogeneous. This novel information may help optimize treatment in individual patients, monitor interventional efficacy and develop new treatments. Moreover, by automating the measurement of regional biomarkers for the 19 different anatomical lung segments, there is an opportunity to embed imaging biomarkers into clinically-acceptable clinical workflows and improve lung disease clinical care...

The Australian population is 10% of Asian origin, and many of our Asian patients have had nasal augmentation using prosthetic material prior to immigration or as medical tourists back in their country of origin. Insertion of nasal prostheses is the most common way to augment the nasal dorsum in the Asian patient and although there is a trend towards autogenous primary augmentation still, the vast majority of patients seen in clinical practice have had augmentation by the insertion of foreign material generally silicone...

As in most sensory systems electrosensory images in weakly electric fish are encoded in two parallel pathways, fast and slow. From the work on wave type electric fish these pathways are thought to encode the time and amplitude of electrosensory signals respectively. This article focuses on the primary afferents giving origin to the slow path of the pulse type weakly electric fish Gymnotus omarorum We found that burst duration coders respond with a high-frequency train of spikes to each electric organ discharge...

INTRODUCTION: A precise quantitative measurement of skeletal muscle mass is fundamental for diagnosing sarcopenia in older individuals. The current techniques of assessment, including dual-energy x-ray absorptiometry (DXA), bioimpedance analysis (BIA), and magnetic resonance imaging (MRI) are either difficult to perform in everyday clinical practice or biased by concurrent clinical confounders. B-mode muscle ultrasound can be helpful in assessing muscle mass and architecture, and thus possibly useful for diagnosing or screening sarcopenia...
