BACKGROUND Cryptosporidium spp. and Giardia duodenalis are important gastrointestinal protists in humans and animals worldwide. In China, bovine cryptosporidiosis and giardiasis are of increasing concern because cattle are important reservoirs of these parasites, which have become potential threats to public health and to large numbers of cattle in recent(More)
Idiopathic small-fiber neuropathy (I-SFN), clinically characterized by burning pain in distal extremities and autonomic dysfunction, is a disorder of small-caliber nerve fibers of unknown etiology with limited treatment options. Functional variants of voltage-gated sodium channel Nav1.7, encoded by SCN9A, have been identified in approximately one-third of(More)
Sodium channel Nav1.9 is expressed in peripheral nociceptive neurons, as well as visceral afferents, and has been shown to act as a threshold channel. Painful peripheral neuropathy represents a significant public health challenge and may involve gain-of-function variants in sodium channels that are preferentially expressed in peripheral sensory neurons.(More)
Cryptosporidium spp. and Giardia duodenalis are important causes of diarrheal diseases in humans and animals worldwide, and there is an increased interest in the role of animals in the mechanical transmission of these protozoa. To examine the role of yaks in this process, we examined the occurrence and genotypes of Cryptosporidium and G. duodenalis in yaks(More)
We recently discovered that the constitutively active Src tyrosine kinase can enhance hyperpolarization-activated, cyclic nucleotide-gated (HCN) 4 channel activity by binding to the channel protein. To investigate the mechanism of modulation by Src of HCN channels, we studied the effects of a selective inhibitor of Src tyrosine kinase,(More)
Two hundred and forty avian broilers were equally divided into four groups, and raised with a corn-soybean basal diet or the same diet supplemented with 300, 600, 900 mg/kg NiCl2 for 42 days. Numbers or percentages of apoptotic splenocytes by flow cytometry (FCM) and TUNEL were higher (p < 0.05 or p < 0.01) in the 300, 600 and 900 mg/kg groups than those in(More)
The purpose of this study was to investigate the oxidative damage induced by dietary nickel chloride (NiCl2) in the intestinal mucosa of different parts of the intestine of broilers, including duodenum, jejunum and ileum. A total of 240 one-day-old broilers were divided into four groups and fed on a corn-soybean basal diet as control diet or the same basal(More)
This study was designed to evaluate the effects of dietary nickel chloride (NiCl2) on the splenic immunity in broilers by observing changes of cytokine mRNA expression and protein levels, immunoglobulin (IgA, IgG, and IgM) contents, and IgA+ B cell and T-cell numbers using the methods of qRT-PCR, flow cytometry (FCM), and ELISA. A total of 240 1-day-old(More)
Cytokines are immunoregulatory proteins which play an important role in the immune system. The purpose of this study was to examine the serum cytokine contents including interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-6 (IL-6), interleukin-10 (IL-10), interferon gamma (IFN-γ), and tumor necrosis factor-alpha (TNF-α) induced by dietary nickel(More)
The aim of this study was to determine the effects of dietary NiCl2 on the development of the small intestine in broilers by the methods of light microscopy, histochemistry and enzyme-linked immunosorbent assay. A total of 240 one-day-old avian broilers were divided into four groups and fed on a corn–soybean basal diet or the same basal diet supplemented(More)
