Molecule characterization of chemosensory and metabolism-related genes in the proboscis of .

The moth species (Möschler) (Lepidoptera: Noctuidae), which has recently been identified as a pest of summer maize ( L.) in China, has demonstrated a rapid proliferation with in the Huang-Huai-Hai Plain region since its initial discovery in Hebei Province in 2005. It has become a prevalent pest of corn crops, and its ability to adapt quickly to its surroundings is currently being investigated.

Chemosensory Protein 2 of Male Is Involved in the Perception of Sex Pheromones and Maize Volatiles.

In moths, the interactions between chemosensory proteins (CSPs) and sex pheromones have yet to be comprehensively investigated. Here, we examined the function of AlepCSP2 in male based on protein expression, molecular docking, site-directed mutagenesis, fluorescence competitive binding analyses, and RNA interference (RNAi) experiments. We found that AlepCSP2 showed strong binding affinity for two sex pheromones and five maize volatiles and that binding was optimal under neutral conditions.

Impact of cirrhosis-related complications on posttransplant survival in patients with acute-on-chronic liver failure.

Background: Acute-on-chronic liver failure (ACLF) is a life-threatening syndrome defined as acute decompensation in patients with chronic liver disease. Liver transplantation (LT) is the most effective treatment. We aimed to assess the impact of cirrhosis-related complications pre-LT on the posttransplant prognosis of patients with ACLF.

Urolithin A ameliorates obesity-induced metabolic cardiomyopathy in mice via mitophagy activation.

Metabolic cardiomyopathy (MC) is characterized by intracellular lipid accumulation and utilizing fatty acids as a foremost energy source, thereby leading to excess oxidative stress and mitochondrial dysfunction. There is no effective therapy available yet. In this study we investigated whether defective mitophagy contributed to MC and whether urolithin A (UA), a naturally occurring microflora-derived metabolite, could protect against MC in experimental obese mice.

AlepPBP2, but not AlepPBP3, may involve in the recognition of sex pheromones and maize volatiles in .

Möschler (Lepidoptera, Noctuidae) is a common maize pest in Europe and Asia. However, there is no long-term effective management strategy is available yet to suppress its population. Adults rely heavily on olfactory cues to locate their optimal host plants and oviposition sites.

Causal Relationships Between Social Isolation and Osteoarthritis: A Mendelian Randomization Study in European Population.

Objective: We aimed to investigate the causal relationships between social isolation and osteoarthritis.

Methods: Publicly available genome-wide association study (GWAS) summary statistics of social isolation and osteoarthritis in European population were obtained from the Neale lab Consortium and the Medical Research Council-Integrative Epidemiology Unit (MRC-IEU) consortium, respectively. Single nucleotide polymorphisms (SNPs) associated with the traits were identified by P < 5×10 and linkage disequilibrium r < 0.

Ligand-binding properties of odorant-binding protein 6 in Athetis lepigone to sex pheromones and maize volatiles.

Background: Athetis lepigone, a noctuid moth feeding on more than 30 different crops worldwide, has evolved a sophisticated, sensitive, and specific chemosensory system to detect and discriminate exogenous chemicals. Odorant-binding proteins (OBPs) are the most important agent in insect chemosensory systems to be explored as an alternative target for environmentally friendly approaches to pest management.

Results: To investigate the olfactory function of A.

Progress in hepatitis B virus-related acute-on-chronic liver failure treatment in China: A large, multicenter, retrospective cohort study using a propensity score matching analysis.

Background: Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) has a high short-term mortality. However, the treatment progression for HBV-ACLF in China in the past decade has not been well characterized. The present study aimed to determine whether the HBV-ACLF treatment has significantly improved during the past decade.

The Causal Relationship Between Body Mass Index and the Risk of Osteoarthritis.

Objective: The study aimed to explore the causal effect of body mass index (BMI) on osteoarthritis.

Methods: The genome-wide association data of BMI and osteoarthritis were obtained via the Mendelian randomization (MR)-base platform. Single nucleotide polymorphisms (SNPs) significantly associated with BMI were identified and used as instrumental variables, and the causal relationship between BMI and osteoarthritis was examined using the two-sample MR research method.

gen. nov., sp. nov., a member of the family , isolated from a saline and alkaline lake sediment.

A non-motile, Gram-staining negative, catalase- and oxidase-positive, crescent-rod shaped bacterium, designated strain CUG 91308, was isolated from a sediment sample of Qinghai Lake, Qinghai Province, China. Colonies on OSM agar were round, smooth, flat and pinkish-orange in colour. Strain CUG 91308 could grow at 15-37 °C, pH 6-12 and in the presence of up to 7.

Current Status and Prospects of Spontaneous Peritonitis in Patients with Cirrhosis.

Spontaneous bacterial peritonitis (SBP) is a common cirrhotic ascites complication which exacerbates the patient's condition. SBP is caused by gram-negative bacilli and, to a lesser extent, gram-positive cocci. Hospital-acquired infections show higher levels of drug-resistant bacteria.

[Progress in diagnosis and treatment of posterior condylar fracture of tibial plateau].

The posterior condylar fracture of the tibial plateau refers to the fracture of the posterior 1/3 area of the tibial plateau. Compared with other clinical types such as Schatzker and AO, the three-column theory is more widely used in the diagnosis and treatment of the posterior condylar fracture of the tibial plateau. There are advantages and disadvantages in learning curve, intraoperative risk and therapeutic effect of minimally invasive methods such as posterior and lateral related approaches, circular external fixator and balloon dilatation, which are commonly used in open surgery.

Risk factors for Clostridium difficile infection in cirrhotic patients.

Background: Cirrhotic patients are susceptible to Clostridium difficile infection (CDI), however, the high risk factors are not clear. The present study aimed to identify the risk factors in cirrhotic patients with CDI.

Methods: A total of 526 cirrhotic patients admitted to our hospital between May 2015 and October 2015 were included in this study.

TRPC6 modulates adhesion of neutrophils to airway epithelial cells via NF-κB activation and ICAM-1 expression with ozone exposure.

Ozone (O) is a major component of air pollution, which has been associated with airway inflammation characterized by the influx of neutrophils in asthmatic subjects. Canonical transient receptor potential 6 (TRPC6) channel is recently identified as a target of oxidative stress which is involved in airway inflammation. However, the regulatory role of TRPC6 in airway epithelial cells and neutrophils has not yet been illuminated in detail.

TRPC6 contributes to LPS-induced inflammation through ERK1/2 and p38 pathways in bronchial epithelial cells.

receptor potential canonical (TRPC) channels are presently an emerging target for airway disorders. Recent evidence has indicated that TRPC6 as a member of the TRPC family plays an important role in airway inflammation, but its precise function in bronchial epithelial cells remains unclear. The aim of this study was to investigate the role of TRPC6 in Toll-like receptor 4 (TLR4)-mediated inflammation in human bronchial epithelial cells stimulated by endotoxin [lipopolysaccharide (LPS)].
