Causes of low mercury levels in fish from the Three Gorges Reservoir, China.

Previous studies have suggested that growth dilution may be an important factor contributing to the low fish Hg levels in China. To evaluate the impact of growth rate to MeHg bioaccumulation in fish in the Three Gorges Reservoir (TGR), this study used two fish species, Aristichthys nobilis (A. nobilis) and Coilia nasus (C.

Effects of Replacing Alfalfa Hay With Native Grass Hay in Pelleted Total Mixed Ration on Physicochemical Parameters, Fatty Acid Profile, and Rumen Microbiota in Lamb.

This study aimed to investigate the effects of replacing alfalfa with native grass on growth performance, meat quality, and rumen microbiota of lambs. Forty-five 6-month-old Ujimqin lambs with live body weight (BW) of 29.50 ± 0.

Polysaccharides from Chrysanthemun indicum L. enhance the accumulation of polysaccharide and atractylenolide in Atractylodes macrocephala Koidz.

Atractylodes macrocephala Koidz. (AM), an herb of traditional Chinese medicine, is well-known for anti-oxidant, anti-tumor and immune regulation potential. However, it is low bioactive compound content that restricts the application of this species.

Characteristics of Antimicrobial-Resistant Strains and Identification of Related Antimicrobial Resistance Gene Mutations.

Multidrug-resistant (MDR) strains have become a great threat to public health. The purpose of this study was to investigate differences in biological characteristics and antimicrobial resistance gene (ARG) mutations of that displayed different levels of antimicrobial resistance. The susceptibility of 74 strains to 9 common antimicrobials was investigated, of which 88% were resistant to 3-4 antimicrobials and 3% to 5-7 antimicrobials.

Multiple insecticide resistance and associated mechanisms to volatile pyrethroid in an Aedes albopictus population collected in southern China.

Conventional and volatile pyrethroids are widely used to control the vectors of dengue arboviral diseases, Aedes albopictus in China. The development of resistance to conventional pyrethroids has become an increasing problem, potentially affecting the use of volatile pyrethroid. The Ae.

Maternal high-fat diet programs cerebrovascular remodeling in adult rat offspring.

Maternal environmental factors such as diet have consequences on later health of the offspring. We found that maternal high-fat diet (HFD) exposure renders adult offspring brain more susceptible to ischemic injury. The present study was further to investigate whether HFD consumption during rat pregnancy and lactation influences the cerebral vasculature in adult male offspring.

Serum IL-33 Is a Novel Diagnostic and Prognostic Biomarker in Acute Ischemic Stroke.

Interleukin-33 (IL-33), a newly recognized IL-1 family member, is expressed in various tissues and cells, and involved in pathogenesis of many human diseases. For example, IL-33 plays a protective role in cardiovascular diseases. However, the role of IL-33 in acute ischemic stroke (AIS) remains unclear.

Maternal high-fat diet influences stroke outcome in adult rat offspring.

Diet-induced epigenetic modifications in early life could contribute to later health problem. However, it remains to be established whether high-fat diet (HFD) consumption during pregnancy and the suckling period could predispose the offspring to stroke. The present study investigated the influence of maternal HFD on stroke outcome in adult offspring.

Maternal high fat diet programs stress-induced behavioral disorder in adult offspring.

Early life exposure to specific environmental factors can contribute to development of behavioral disorders in adulthood. Although maternal high fat diet (HFD) consumption during the perinatal period has been reported to program offspring behavior, the underlying mechanisms remain to be elucidated. The present study was designed to evaluate the influence of maternal HFD on offspring behavior under nonstressed and stressful conditions, using male Sprague-Dawley offspring, which mothers were fed with HFD or normal diet (ND), receiving chronic unpredictable mild stress (CUMS) in the adulthood.

Construction and characterization of the transformation-competent artificial chromosome (TAC) libraries of Leymus multicaulis.

Transformation-competent artificial chromosome system is able to clone and transfer genes efficiently in plants. In order to clone genes highly tolerant to barley yellow dwarf virus (BYDV), Aphids, drought and salt from Leymus multicaulis, the two TAC genomic libraries I and II were constructed in vector pYLTAC17 and pYLTAC747H/sacB, which contain about 165000 and 236000 recombinant clones separately. The genome coverage of the two libraries was totally estimated to be about 3-5 haploid genome equivalents, as size selection of genomic DNA fragments was approximately from 9 to 300 kb.
