The regions of the olfactory epithelium affected by hydrogen sulfide (H2S) toxicity in the rat present a striking similarity with the developmental olfactory zone 1 described in the mouse. This zone which is the only region containing neurons expressing NAD(P)H quinone dehydrogenase 1 (NQO1) is involved in complex behavioral responses in rodents, and other mammals, triggered by specific olfactory stimuli. We therefore sought to determine whether 1) olfactory neurons expressing NQO1 are located in the same regions in the rats and in the mice and 2) there is an overlap between olfactory neurons expressing this protein and those affected by the toxicity of H2S...

In the current study, an improved NGS approach was developed to study the B-cell repertoire evolution in a simple mouse immunization model including only two DNA immunizations. The combination of 5'RACE and Ion Torrent long reads enabled unbiased immunoglobulin repertoire analysis even from small amounts of peripheral mouse blood. The B-cell population expanded by the vaccine displayed a relatively strong clonality. Upon priming with the first vaccine dose, we observed a consistent pattern of V-segment gene and CDR3 usage (public specificities)...

Air pollution and lung cancer are closely related. In 2013, the World Health Organization listed outdoor air pollution as carcinogenic and regarded it as the most widespread carcinogen that humans are currently exposed to. Here, grey correlation and data envelopment analysis methods are used to determine the pollution factors causing lung cancer among residents in Nanchang, China, and identify population segments which are more susceptible to air pollution. This study shows that particulate matter with particle sizes below 10 micron (PM10) is most closely related to the incidence of lung cancer among air pollution factors including annual mean concentrations of SO₂, NO₂, PM10, annual haze days, and annual mean Air Pollution Index/Air Quality Index (API/AQI)...

Urbanization poses a global challenge to species conservation. This is primarily understood in terms of physical habitat loss, as agricultural and forested lands are replaced with urban infrastructure. However, aquatic habitats are also chemically degraded by urban development, often in the form of toxic stormwater runoff. Here we assess threats of urbanization to coho salmon throughout developed areas of the Puget Sound Basin in Washington, USA. Puget Sound coho are a sentinel species for freshwater communities and also a species of concern under the U...

Over the years, advances in immunohistochemistry techniques have been a critical step in detecting and mapping neuromodulatory substances in the central nervous system. The better quality and specificity of primary antibodies, new staining procedures and the spectacular development of imaging technologies have allowed such progress. Very recently, new methods permitting tissue transparency have been successfully used on brain tissues. In this work, we combined whole-mount immunostaining for tyrosine hydroxylase (TH), oxytocin (OXT) and arginine vasopressin (AVP), with iDISCO+ clearing method, light-sheet microscopy and semi automated counting of 3D-labelled neurons to obtain a 3D distribution of these neuronal populations in a 5-day postnatal (P5) mouse brain...

Characterization and quantification of tumour clonal populations over time via longitudinal sampling are essential components in understanding and predicting the response to therapeutic interventions. Computational methods for inferring tumour clonal composition from deep-targeted sequencing data are ubiquitous, however due to the lack of a ground truth biological data, evaluating their performance is difficult. In this work, we generate a benchmark data set that simulates tumour longitudinal growth and heterogeneity by in vitro mixing of cancer cell lines with known proportions...

BACKGROUND: In 2012, the Ontario government withdrew public insurance coverage of imaging tests for uncomplicated low back pain. We studied the impact of this restriction on test ordering by physicians. METHODS: We compared the numbers of lumbar spine radiography, computed tomography (CT) and single-segment magnetic resonance imaging (MRI) studies ordered by physicians in the 3 years before and after the policy change. We linked claims data from the Ontario Health Insurance Program with physician details to calculate rates per test-ordering physician...

This article reports on an observational and treatment case series involving 22 adolescents and preadolescents treated over a 15 year period who had or appeared to be developing idiopathic scoliosis (IS). Common patterns of muscle and fascial asymmetry were observed and treated. Most of these individuals had spinal area pain and the trigger points (TrPs) apparently responsible for this pain were located in muscles at some distance from the spine, yet referred pain to locations throughout the thoracolumbar spine...

The concept of multimorbidity has risen in popularity over the past few years. It is use has led to, or coincided with, an increased recognition that patients often have more than one health problem which should not be treated in isolation. The motivation for more holistic, person-centred care that lies behind multimorbidity is to be welcomed. The 2016 National Institute for Health and Care Excellence multimorbidity management guideline helpfully makes recommendations in key areas that are important in the care of patients with complicated medical problems...

In motion analysis, the hip joint center (HJC) is used to define the proximal location of the thigh segment and is also the point about which hip moments are calculated. The HJC cannot be palpated; its location must be calculated. Functional methods have been proposed but are difficult to perform by some clinical populations. Therefore, regression methods are utilized, but yield large errors in estimating the HJC location. These prediction methods typically utilize the anterior and posterior superior iliac spines, where excessive adipose tissue makes correctly locating difficult...

Cardiovascular disease (CVD) accounts for approximately one-third of all global deaths, and acute coronary syndrome (ACS) is the most severe form of CVD. It is of notable importance to develop ACS strategies for reducing major adverse cardiac events (MACE) and preventing complications. In the Taiwan ACS Full Spectrum Registry, 1-year mortality among patients with ST-segment elevation myocardial infarction, non ST-segment elevation myocardial infarction and unstable angina was 6.1%, 10.1%, and 6.2%, respectively...

Neutral lipids packed in lipid droplets (LDs) are essential as a source of fuel for organisms, and specialized storing cells, the adipocytes, provide a buffer for energy variations. Many modern-society-disorders are connected with excess accumulation or deficiency of LDs in adipose tissue. Intracellular LD number and size distribution reflect the tissue conditions, while the associated mechanisms and genes rs are still poorly understood. Large-scale genetic screens using human in vitro differentiated primary adipocytes require cell samples donated from many patients...

BACKGROUND: Glycated hemoglobin (HbA1c) is one of the laboratory tests recommended by the ADA to screen for diabetes mellitus (DM). It is particularly suitable for population segments that cannot or are unwilling to fast for a screening test. Our study aims to determine if HbA1c would be a useful tool to screen for DM in a real world setting if ADA guidelines for repeat testing to confirm the diagnosis of DM are strictly adhered to. METHODS: We carried out a retrospective database study by extracting demographic and laboratory data from a chronic disease registry which collects data on adults from three tertiary hospitals and nine large primary care clinics in Singapore...
