Mesenchymal stem cells (MSCs) possess self-proliferation and multi-directional differentiation abilities. Previous studies on MSCs have mostly focused on the bone marrow, lungs, pancreas and umbilical cord blood, with few studies on metanephric tissues in ducks. For the present study, the Beijing duck was selected as an experimental animal. Duck embryo metanephric mesenchymal stem cells (MMSCs)...
Current models of necrotizing enterocolitis (NEC) propose that intraluminal microbes destroy intestinal mucosa and activate an inflammatory cascade that ends in necrosis. We suggest an alternate hypothesis wherein NEC is caused by injury to Paneth cells (PCs) in the intestinal crypts. PCs are specialized epithelia that protect intestinal stem cells from pathogens, stimulate stem cell differenti...
INTRODUCTION The presence of heavy metals such as cadmium in drinking water resources can be dangerous for human because of toxicity and biological accumulation. The consumption of water which contains Cd in high concentration can lead to Bone and Kidney diseases. MATERIAL AND METHODS In this present study, the researcher collected 432 samples of bottled water in the popular marks in summer a...
The organization of electron transport in photosystem II of spinach (Spinacia oleracea) chloroplasts was studied by means of various chelators and uncouplers. The partial reactions used included H(2)O-->methyl viologen, H(2)O-->silicomolybdic acid H(2)O-->ferricyanide, and H(2)O-->dimethylbenzoquinone. Three types of chelator inhibition were found (a) inhibition common to all pathways and presu...
The bone marrow cavity (BMC) has recently been identified as an alternative site to the liver for islet transplantation. This study aimed to compare the BMC with the liver as an islet allotransplantation site in diabetic monkeys. Diabetes was induced in Rhesus monkeys using streptozocin, and the monkeys were then divided into the following three groups: Group1 (islets transplanted in the liver ...
