Study on the signaling pathways involved in the anti-hyperglycemic effect of raspberry ketone on zebrafish using integrative transcriptome and metabolome analyses.

Hyperglycemia leads to increased oxidative stress in mitochondria, an abnormal activation of intracellular inflammatory signals, and mediate multiple dysfunctions. Raspberry ketone (RK) is an aromatic phenolic compound found in many plants and could contribute to weight loss, restore impaired glucose tolerance, and has antioxidant properties. In our investigation, RK could greatly prevent islet, brain and other tissue damage caused by hyperglycemia in a zebrafish model with streptozotocin (STZ)-induced hyperglycemia.

Reducing residual chlortetracycline in wastewater using a whole-cell biocatalyst.

Antibiotic contamination has become an increasingly important environmental problem as a potentially hazardous emergent and recalcitrant pollutant that poses threats to human health. In this study, manganese peroxidase displayed on the outer membrane of Escherichia coli as a whole-cell biocatalyst (E. coli MnP) was expected to degrade antibiotics.

Lrp13a and Lrp13b serve as vitellogenin receptors in the ovary of zebrafish†.

In oviparous animals, egg yolk is largely derived from vitellogenin, which is taken up from the maternal circulation by the growing oocytes via the vitellogenin receptor. Recently, a novel member of the lipoprotein receptor superfamily termed low-density lipoprotein receptor-related protein 13 was identified and proposed as a candidate of vitellogenin receptor in oviparous animals. However, the roles of low-density lipoprotein receptor-related protein 13 in vitellogenesis are still poorly defined.

Effects of on Growth and Photosynthetic Characteristics of under Different Nitrogen Forms.

Nitrogen fertilizer increases agricultural yields but increases economic costs and causes a series of environmental problems. Arbuscular mycorrhizal fungi (AMF) have the potential to be used as biological fertilizer. However, the influence of nitrogen form on plant growth responsiveness to AMF inoculation is poorly understood.

Pyroptosis: A pro-inflammatory type of cell death in cardiovascular disease.

Pyroptosis is a pro-inflammatory type of regulated cell death (RCD) characterized by gasdermin D (GSDMD)-mediated membrane pore formation, cell swelling and rapid lysis, followed by the massive release of pro-inflammatory mediators such as interleukin-1β and interleukin-18. There are two main pathways of pyroptosis: the caspase-1-mediated canonical pathway and the caspase-4/5/11-mediated noncanonical pathway. However, the caspase-3-gasdermin E (GSDME) pathway and caspase-8-GSDMD pathway also induce pyroptosis.

High Risk of Influenza Virus Infection Among Swine Workers: Examining a Dynamic Cohort in China.

Background: China is thought to be a hotspot for zoonotic influenza virus emergence, yet there have been few prospective studies examining the occupational risks of such infections.

Methods: We present the first 2 years of data collected from a 5-year, prospective, cohort study of swine-exposed and -unexposed participants at 6 swine farms in China. We conducted serological and virological surveillance to examine evidence for swine influenza A virus infection in humans.

Prospective surveillance for influenza. virus in Chinese swine farms.

Pork production in China is rapidly increasing and swine production operations are expanding in size and number. However, the biosecurity measures necessary to prevent swine disease transmission, particularly influenza. viruses (IAV) that can be zoonotic, are often inadequate.

Synthesis of Alkyl Indium Reagents by Using Unactivated Alkyl Chlorides and Their Applications in Palladium-Catalyzed Cross-Coupling Reactions with Aryl Halides.

An efficient method for the preparation of alkyl indium reagents by using unactivated and cheap alkyl chlorides as substrates in the presence of indium and LiI was developed. The thus-formed alkyl indium species effectively underwent palladium-catalyzed cross-coupling reactions with aryl halides with wide functional group tolerance.

Evidence for Cross-species Influenza A Virus Transmission Within Swine Farms, China: A One Health, Prospective Cohort Study.

Background: Our understanding of influenza A virus transmission between humans and pigs is limited.

Methods: Beginning in 2015, we used a One Health approach and serial sampling to prospectively study 299 swine workers and 100 controls, their 9000 pigs, and 6 pig farm environments in China for influenza A viruses (IAVs) using molecular, culture, and immunological techniques. Study participants were closely monitored for influenza-like illness (ILI) events.

Consistently low prevalence of syphilis among female sex workers in Jinan, China: findings from two consecutive respondent driven sampling surveys.

Background: Routine surveillance using convenient sampling found low prevalence of HIV and syphilis among female sex workers in China. Two consecutive surveys using respondent driven sampling were conducted in 2008 and 2009 to examine the prevalence of HIV and syphilis among female sex workers in Jinan, China.

Methods: A face-to-face interview was conducted to collect demographic, behavioral and service utilization information using a structured questionnaire.

Predictors of consistent condom use based on the Information-Motivation-Behavioral Skills (IMB) model among female sex workers in Jinan, China.

Background: Female commercial sex workers (FSWs) are at high risk of human immunodeficiency virus (HIV) transmission in China. This study was designed to examine the predictors of condom use with clients during vaginal intercourse among FSWs based on the Information-Motivation-Behavioral Skills (IMB) model and to describe the relationships between IMB model constructs.

Methods: A cross-sectional study was conducted in Jinan of Shandong Province, from May to October, 2009.
