Beta catenin gene can inhibit the chondrogenic differentiation of human adipose tissue derived stem cells, while sex determining region Y-box9 promote cells. However, it is still necessary to study role combination two genes in early The purpose this was investigate whether knockdown and overexpression combined with modification cells could Therefore, divided into four groups or lentivirus vect...

The Effect of Melissa officinalis Extract on Streptozotocin-Induced Diabetes in Rats: A Stereological Study Pancreatic Islets and Beta-cells

background : clostridium perfringens type c strains cause severe necrotizing enteritis in sheep, calves, goats, pigs and humans. beta-toxin is introduced to be the essential virulence factor of this microorganism. in the present study, a new method was established for the purification of beta toxin from culture supernatant fluid of c. perfringens type c vaccinal strain. methods : the four steps...

Background: Dendritic cells (DC) are a key regulator of the immune response, and interferon- beta (IFN-β) is considered an immunomodulatory molecule for DC. Objective: The purpose of this study was to evaluate the ability of IFN-β treated DC to induce cytokine secretion by CD4+ T cells. Methods: Dendritic cells were generated from blood monocytes with granulocyte-monocyte colony-stimulating fac...

Several lines of evidence suggest that some neurotoxicity in AD is due to proteolytic fragments of APP. In this study, we compared the potency of neurotoxicity induced by CT with that of A-beta neurotoxicity and our results showed that various CT peptide fragments (CTFs; CTF99, AICD, CTF31) caused neurotoxicity in cultured cells and primary cortical neurons, induced strong non-selective inward ...

introduction: skin dose and depth dose distribution of some beta sources that can contaminate skin or protective clothing covering the skin have been calculated using varskin2. materials and methods: in this research, absorbed dose to skin and depth dose from the skin surface have been calculated for 90sr/90y, 147pm, 32p beta emitter radioisotopes by using input parameters: activity of source, ...

Understanding the origins of insulin-producing beta cells of the pancreas could lead to new treatments for diabetes. Collombat et al. (2009) now show that in response to injury, a population of pancreatic progenitor cells can give rise to glucagon-expressing alpha cells that then transdifferentiate into beta cells.

Prenatal androgen exposure induces metabolic disorders in female offspring. However, the long-term effect of maternal testosterone excess on glucose metabolism, especially pancreatic beta-cell function, is rarely investigated. Our current study mainly focused effects prenatal metabolism and beta- cell function aged By using mice their offspring as animal models, we found that treatment induced ...

Abstract Metabolic diseases are associated with an increased risk of severe COVID-19 and conversely, new-onset hyperglycemia complications preexisting diabetes have been observed in patients. Here, we performed a comprehensive analysis pancreatic autopsy tissue from patients using immunofluorescence, immunohistochemistry, RNA scope electron microscopy detected SARS-CoV-2 viral infiltration beta...
