Four enteropathogenic Escherichia coli (EPEC) strains belonging to the O55 serogroup (G21 and G30 [both O55:H6], G35 [O55:H-], and G58 [O55:H7]) were tested for their tissue tropism by using human intestinal in vitro organ culture. Strains showed restricted adhesion with attaching-and-effacing activity to follicle-associated epithelium of Peyer's patches, with no apparent adhesion to duodenum o...

Objective To investigate the relationship between abdominal adipose tissue distribution, β-cell function, and insulin sensitivity (IS) in a Chinese population. Methods One hundred and eighty-eight healthy subjects (healthy group), 239 with normal glucose, and 1~4 abnormal metabolic traits (metabolic dysfunction group, MD group) and 125 with hyperglycemia (hyperglycemia group) were studied. HO...

Concrete is the most adaptable, long-lasting, and dependable construction material on planet. There are numerous environmental concerns associated with production of OPC, natural sand becoming more expensive scarce as a result unlawful river dredging. The greatest replacement for traditional concrete geopolymer low calcium fly ash. purpose this paper to investigate mechanical properties grades ...

Type 2 diabetes is characterized by a reduction in both insulin sensitivity and glucose-stimulated insulin secretion (GSIS). Although insulin resistance usually precedes -cell dysfunction, the role of the latter in the development of the disease is unclear. The detrimental effect that chronic hyperglycemia exerts on -cell function is well established and may contribute to further deterioration ...
