Rabbits are one of the few mammalian species that appear to be resistant to transmissible spongiform encephalopathies due to the structural characteristics of the rabbit prion protein (RaPrP(C)) itself. Here, we determined the solution structures of the recombinant protein RaPrP(C)-(91-228) and its S173N variant and detected the backbone dynamics of their structured C-terminal domains-(121-228)...

Two highly potent and selective cystic fibrosis (CF) transmembrane regulator (CFTR) inhibitors have been identified by high-throughput screening: the thiazolidinone CFTR(inh)-172 [3-[(3-trifluoromethyl)phenyl]-5-[(4-carboxyphenyl)methylene]- 2-thioxo-4-thiazolidinone] and the glycine hydrazide GlyH-101 [N-(2-naphthalenyl)-((3,5-dibromo-2,4-dihydroxyphenyl)methylene)glycine hydrazide]. Inhibitio...

The bovine growth hormone gene (bGH) possesses three haplotypes, A, B and C, that differ by amino acid mutations at positions 127 and 172 in the fifth exon: (leucine 127, threonine 172), (valine 127, threonine 172) and (valine 127, methionine 172) respectively. The correlation between meat quality or carcass weight and these haplotypes was investigated in Japanese black cattle. Altogether, 940 ...

MicroRNAs (miRNAs), a class of small RNAs, are important molecules that influence several developmental processes and regulate RNA interference (RNAi), and are abundant in animals, plants, and plant tissues that are traditionally consumed in the diet. The survival of plant small RNAs from the diet in animals, however, remains unclear, and the persistence of miRNAs from dietary plants in the ani...

To estimate the prevalence and public health significance of cryptosporidiosis in preweaned calves in China, 801 fecal samples from eight farms in seven areas in Henan Province were examined for Cryptosporidium oocysts. The overall infection rate of Cryptosporidium was 21.5%, with the farm in Xinxiang having the highest prevalence (40%). No significant difference in infection rates was observed...

AMP-activated protein kinase (AMPK) is a major mediator of the exercise response and a molecular target to improve insulin sensitivity. To determine if the anaerobic component of the exercise response, which is exaggerated when sprint is performed in severe acute hypoxia, influences sprint exercise-elicited Thr(172)-AMPKα phosphorylation, 10 volunteers performed a single 30-s sprint (Wingate te...

BACKGROUND Significant portion of alphaA-crystallin in human lenses exists as C-terminal residues cleaved at residues 172, 168, and 162. Chaperone activity, determined with alcohol dehydrogenase (ADH) and betaL-crystallin as target proteins, was increased in alphaA(1-172) and decreased in alphaA(1-168) and alphaA(1-162). The purpose of this study was to show whether the absence of the C-termina...

Primary airway epithelial cells grown in air-liquid interface differentiate into cultures that resemble native epithelium morphologically, express ion transport similar to those in vivo, and secrete cytokines in response to stimuli. Comparisons of cultures derived from normal and cystic fibrosis (CF) individuals are difficult to interpret due to genetic differences besides CFTR. The recently di...

24 25 To estimate the prevalence and public health significance of cryptosporidiosis in 26 pre-weaned calves in China, 801 fecal samples from eight farms in seven areas in 27 Henan Province were examined for Cryptosporidium oocysts. The overall infection 28 rate of Cryptosporidium was 21.5%, with the farm in Xinxiang having the highest 29 prevalence (40%). No significant difference in infection...
