Abstract The present work investigated the effect of camel's fetal fluids on a variety of bacterial and fungal pathogens. Ten samples of camel's amniotic and allantoic fluids were collected aseptically during parturition and their antimicrobial activities were evaluated by disc diffusion method and minimum inhibitory concentration (MIC) assay. The majority of tested pathogens were inhibited by both fluids up to 25% concentration. The fluids showed zones of inhibition ranging from...
Abstract Vibrio parahaemolyticus (VP) is a marine bacterium that opportunistically caused foodborne gastroenteritis in human and some diseases in marine animals. The isolated strain of V. parahaemolyticus WS001 from Samut Sakhon, Thailand has a presence of ldh (~ 450 bp) toxA (~ 333 bp) and toxB (~ 1269 bp) genes which showed pathogenicity in shrimp. This strain is suspected as low pathogenicity in human due to the lack of tdh and trh genes for encoding thermostable direct hemolysin...
Abstract Xylella fastidiosa is a Gram-negative and nutritionally fastidious bacterial pathogen causing Pierce’s disease (PD) of grapevine and other plant diseases. X. fastidiosa strain ATCC 35879T which originated from Florida is the designated type strain for the species and for subsp. fastidiosa.

Abstract The last decade has witnessed growth in scientific interest towards studying the biodiversity and ecology in extreme environments. Acid Mine Drainage (AMD), formed through the bio-oxidation of metal sulphides, is a typical extreme environment that is inhospitable to most life forms. Through the application of traditional culture-based molecular techniques, it has been established that AMD is home to a low diversity, specialized and novel microbial community that plays...
Abstract For several decades, dirigent (DIR) domain-containing proteins have been assumed to be green lineage-specific, responsible for the defence response and lignan/lignin biosynthesis. Despite their high potential in terms of biotechnology and chemistry, to date there have been very few well-studied plant DIRs. However, recent achievements in sequencing technologies have allowed for discovery of DIR genes in bacteria. This prospective study suggests expansion of the focus...
Abstract Together with the worldwide Washoku (traditional Japanese foods and drinks) boom, interest in sake, a traditional Japanese alcoholic drink, is increasing around the world. There are few scientific analyses and studies on the production of sake or the final product itself. We show the diversity of bacterial contaminants during sake production and investigated the effects of different ingredients on sake (for example, amino acids). The koji mold Aspergillus oryzae converts...

New Findings It appears that the noradrenergic neurotransmitter system hastens central fatigue during prolonged exercise, a finding that coincides with a faster rate of increase in the rating of perceived exertion. Mental fatigue will affect several neurotransmitter systems, with presumably an important role for dopamine and adenosine, in multiple brain regions such as the prefrontal cortex and the anterior cingulate cortex Abstract In sports and exercise science fatigue...
New Findings What is the central question of this study? Can antiarrhythmic drug effects on repolarization, conduction time and excitation wavelength in premature beats be determined by prior cardiac activation frequency? What is the main finding and its importance? In premature beats induced after a series of cardiac activations at the slow rate, antiarrhythmics prolong repolarization, but evoke little or no conduction delay, thus increasing the excitation wavelength, which indicates...

Abstract Psychological states can influence motor performance and learning. In Parkinson's disease (PD), placebo effects or expectancies for pharmacological treatment benefits are not uncommon, but little is known about whether self‐efficacy, beliefs about personal performance capabilities, may play a role in this population. To address this question, we investigated whether experimental manipulations designed to enhance self‐efficacy would benefit motor performance and learning in PD. A motor...

Abstract Due to its hemizygous inheritance and role in sex determination, the X chromosome is expected to play an important role in the evolution of sexual dimorphism, and to be enriched for sexually antagonistic genetic variation. By forcing the X chromosome to only be expressed in males over > 40 generations, we changed the selection pressures on the X to become similar to those experienced by the Y. This releases the X from any constraints arising from selection in females, and should lead...

Many increasing documents have proved that alternative polyadenylation (APA) events with different polyadenylation sites (PAS) contribute to posttranscriptional regulation. However, little is known about the detailed molecular features of PASs and its role in porcine fast and slow skeletal muscles through microRNAs (miRNAs) and RNA binding proteins (RBPs). In this study, we combined single-molecule real-time sequencing and Illumina RNA-seq datasets to comprehensively analyze polyadenylation in pigs....
Recent comparisons between plant and animal viruses reveal many common principles that underlie how all viruses express their genetic material, amplify their genomes, and link virion assembly with replication. Cauliflower mosaic virus (CaMV) is not infectious for human beings. Here, we show that CaMV transactivator/viroplasmin protein (TAV) shares sequence similarity with and behaves like the human ribonuclease H1 (RNase H1) in reducing DNA/RNA hybrids detected with S9.6 antibody in HEK293T cells....
Aims. Liver cancer is a multietiological disease that has multiple factors contributing to the hepatocarcinogenic process, e.g., hepatitis viruses, carcinogens, male sex, or metabolic factors. Notably, emerging evidence reported that gut microbiota is crucial to the pathogenesis of hepatocellular carcinoma (HCC) via activation of innate immunity. However, the effect of time to gut microbiota exposure after birth is unknown. Using a germ-free animal housing environment, instead of antibiotics, we...
