BACKGROUND Vitamin D status in relation to pancreatic cancer risks is still inconsistent. This study was performed to evaluate the association between vitamin D status and risk of pancreatic cancer using a meta-analysis approach. METHODS A systemic review of all relevant literature in English was performed by searching Pubmed, Web of Science and Embase to(More)
The cytokine interleukin-22 (IL-22) and its receptor are present in the tumor microenvironment. Their function in pancreatic ductal adenocarcinoma (PDAC) remains largely unknown. The goal of the present study was to measure the expression of IL-22 and IL-22R in PDAC and assess their relationship with clinicopathological features and prognosis. The(More)
Rhabdomyolysis presenting with severe hypokalemia as the first manifestation of primary hyperaldosteronism is extremely rare. Two middle-aged Chinese females were admitted to our emergency department for muscular weakness and limb pain, and both have the history of early onset hypertension. Laboratory test showed elevated creatinine phosphokinase (4, 907(More)
A dose-response experiment with 8 dietary choline levels (302, 496, 778, 990, 1,182, 1,414, 1,625, and 1,832 mg/kg) was conducted with male White Pekin ducks to estimate the choline requirement from hatch to 21 d of age. Three hundred eighty-four 1-d-old male White Pekin ducks were randomly assigned to 8 dietary treatments, each containing 6 replicate pens(More)
Stevioside, a diterpene glycoside isolated from Stevia rebaudiana, has been reported to have anti-inflammatory properties. However, the underlying molecular mechanisms are not well understood. The objective of this study was to investigate the molecular mechanism of stevioside in modifying lipopolysaccharide (LPS)-induced signal pathways in RAW264.7 cells.(More)
Retinoic acid (RA) is a small molecular derivative of vitamin A that is stored in quiescent stellate cells in pancreas stroma. Cancer associated fibroblasts (CAFs) are activated fibroblast cells in pancreatic ductal adenocarcinoma tumor microenvironment. We treated CAFs with RA and found that these cells became static due to the low expression of α-SMA,(More)
Bacterial binding to host cell surface is considered an important initial step in the pathogenesis of many infectious diseases including meningitis. Previous studies using a laboratory Escherichia coli (E. coli) strain HB101 possessing a recombinant plasmid carrying the cloned S fimbriae gene cluster have shown that S fimbriae are the major contributor to(More)
Acute pancreatitis, a common necroinflammatory disease of the pancreas, remains an unsolved problem that is associated with significant morbidity and mortality. Intra-acinar cell activation of digestion enzymes triggers the events of acute pancreatitis and stimulates the production of inflammatory cytokines. Finally, inflammatory cytokines trigger(More)
This paper proposes a key management mechanism by DH distributed key tree for the DHT network, which is based on the DHT network routing mechanism and network topology structure. The scheme uses the DH algorithm for key agreement, to ensure that the nodes in the DHT network are able to maintain a limited number of keys, and on this basis to complete(More)
Two experiments were conducted to study the effects of stocking density on growth performance, carcass yield, and foot pad lesions of White Pekin ducks from hatch to 14 d of age (experiment 1) and from 14 to 42 d of age (experiment 2), respectively. All ducks were reared in raised plastic wire-floor pens with a pen size of 30 m(2), and males and females(More)
