[Wild boar resource and its conflict with human in Zhejiang Province, East China].

Human-wildlife conflict is one of the important research topics in biodiversity and conservation. Understanding the status of wildlife resources and its conflict with human could promote the sustainable protection and management of wildlife. Wild boar () is one of the most widely distributed ungulates in the world, with an increasing population and recently rising levels of conflict with human.

Multi-pathway exposure assessment of organophosphate flame retardants in a southern Chinese population: Main route identification with compound-specificity.

In this study, we conducted comprehensive organophosphorus flame retardant (PFR) exposure assessments of both dietary and non-dietary pathways in a rural population in southern China. Skin wipes were collected from 30 volunteers. Indoor and outdoor air (gas and particles), dust in the houses of these volunteers, and foodstuffs consumed by these volunteers were simultaneously collected.

Characteristics of traumatic brain injury models: from macroscopic blood flow changes to microscopic mitochondrial changes.

Controlled cortical impingement is a widely accepted method to induce traumatic brain injury to establish a traumatic brain injury animal model. A strike depth of 1 mm at a certain speed is recommended for a moderate brain injury and a depth of > 2 mm is used to induce severe brain injury. However, the different effects and underlying mechanisms of these two model types have not been proven.

A Review of the Pharmacokinetic Characteristics of Immune Checkpoint Inhibitors and Their Clinical Impact Factors.

Immune checkpoint inhibitors (ICIs) have been shown to be significant in improving the overall survival rate in certain malignancies with poor prognoses. However, only 20-40% of patients achieve long-term benefits, highlighting the relevance of the factors that influence the treatment, which can help clinicians improve their results and guide the development of new immune checkpoint therapies. In this study, the current pharmacokinetic aspects associated with the ICIs and the factors influencing clinical efficacy were characterised, including in terms of drug metabolism, drug clearance, hormonal effects and immunosuppressive effects.

Newly Detected Transmission of bla by Outer Membrane Vesicles in Klebsiella Pneumoniae.

Objective: The prevalence of carbapenem-resistant Klebsiella pneumoniae (CR-KP) is a global public health problem. It is mainly caused by the plasmid-carried carbapenemase gene. Outer membrane vesicles (OMVs) contain toxins and other factors involved in various biological processes, including β-lactamase and antibiotic-resistance genes.

Comparative in vitro metabolism of short chain chlorinated paraffins (SCCPs) by human and chicken liver microsomes: First insight into heptachlorodecanes.

Short chain chlorinated paraffins (SCCPs) are emerging persistent organic pollutants of great concern due to their ubiquitous distribution in the environment. However, little information is available on the biotransformation of SCCPs in organisms. In this study, a chlorinated decane: 1, 2, 5, 5, 6, 9, 10-heptachlorodecanes (HeptaCDs) was subjected to in vitro metabolism by human and chicken liver microsomes at environmentally relevant concentration.

A Kv1.3 channel-specific blocker alleviates neurological impairment through inhibiting T-cell activation in experimental autoimmune encephalomyelitis.

Aim: Multiple sclerosis (MS) is a neurological autoimmune disorder characterized by mistaken attacks of inflammatory cells against the central nervous system (CNS), resulting in demyelination and axonal damage. Kv1.3 channel blockers can inhibit T-cell activation and have been designed for MS therapy.

Evaluation of root-knot nematode disease control and plant growth promotion potential of biofertilizer Ning shield on Trichosanthes kirilowii in the field.

Biofertilizer Ning shield was composed of different strains of plant growth promotion bacteria. In this study, the plant growth promotion and root-knot nematode disease control potential on Trichosanthes kirilowii in the field were evaluated. The application of Ning shield significantly reduced the diseases severity caused by Meloidogyne incognita, the biocontrol efficacy could reached up to 51.

Characteristics and health risk assessment of heavy metals exposure via household dust from urban area in Chengdu, China.

To investigate the characteristics of heavy metals (Cr, Cd, Pb, Zn, Cu and Ni) in household dust in urban household environment of Chengdu, China, 90 household dust samples were collected from 6 districts of the city. The information of houses and residents were also recorded during dust sampling to identify the correlations between heavy metals in household dust and the house attributes. And also the principal component analysis and cluster analysis for sources and impactor factors.

An improved strategy for stable biocontrol agents selecting to control rice sheath blight caused by Rhizoctonia solani.

Rice sheath blight caused by Rhizoctonia solani Kühnis increasingly threatening rice production in China. DNA fingerprints of 220 R. solani strains isolated in 11 provinces of China were established by random amplified polymorphic DNA (RAPD)-PCR.

Pollution characteristics and risk assessment of human exposure to oral bioaccessibility of heavy metals via urban street dusts from different functional areas in Chengdu, China.

Urban street dusts were collected in commercial area (CA), traffic area (TA), educational area (EA), residential area (RA) and parks area (PA) of Chengdu, China, to investigate the concentrations of heavy metals (Pb, Zn, Cu, Ni, Cd and Cr), and analyzed to evaluated possible sources and health risk assessment. The average concentrations (mg/kg) of Pb (82.3), Zn (296), Cu (100), Cd (1.

Overexpression of BUB1B contributes to progression of prostate cancer and predicts poor outcome in patients with prostate cancer.

BUB1 mitotic checkpoint serine/threonine kinase B (BUB1B) is a member of the spindle assembly checkpoint protein family, which has been proven to be associated with many kinds of cancers. The aim of this study was to investigate whether BUB1B was correlated with progression and prognosis in patients with prostate cancer (PCa) and how BUB1B regulated the proliferation, migration, and invasion of PCa cell lines. Compared to benign prostate cells and tissues, both messenger RNA and protein expressions of BUB1B were statistically increased in PCa cell lines and tumor tissues.

Effect of 1,25-dihydroxyvitamin D₃on regulatory T cells in ovariectomized mice.

Objective: To investigate the correlation between regulatory T (Treg) cells and postmenopausal osteoporosis and the antiosteoporotic effect of 1,25-dihydroxyvitamin D3 [1,25(OH)₂D₃] in relation to Treg cells.

Methods: Fifty female BALB/c mice were randomly divided into five groups: the basal control (BAS), Sham, ovariectomy (OVX), OVX+diethylstilbestrol (OVX+DES), and OVX+1,25(OH)₂D₃. Tibias were harvested and processed with decalcification for quantitative bone histomorphometry.

[Study on chlorinated disinfection byproducts and the relevant health risk in tap water of J City].

J City lies in the downstream of Taihu Lake and its water source was micro-polluted by the well-developed industry and agriculture inside the city and in the upper stream. Tap water of J City is characterized as high concentrations of organics and ammonia nitrogen, and chlorinated disinfection byproducts (CDBPs), which has drawn many public concerns for the health risk. Tap water was sampled in May, August, October of 2012 and January of 2013.

[Mechanism of membrane fouling and filtration characteristics in a membrane bioreactor for industrial wastewater treatment].

The influence of mixed liquor suspended solids (MLSS), soluble microbial product (SMP), extracellular polymeric substance (EPS), colloidal particles and other factors contributed to membrane fouling was analyzed in this pilot test by membrane bioreactor (MBR) process for the leather printing and dyeing industrial park mixed wastewater treatment.

Molecular epidemiology of HCV monoinfection and HIV/HCV coinfection in injection drug users in Liuzhou, Southern China.

Background: Hepatitis C virus (HCV) mono-infection and HCV/HIV (human immunodeficiency virus) co-infection are growing problems in injection drug users (IDU). Their prevalence and genotypic patterns vary with geographic locations. Access to harm reduction measures is opening up opportunities for improving the HIV/HCV profiling of IDU in China, where IDUs account for a significant proportion of the two infections especially in the southern part of the country.
