Role of calcium/calmodulin signaling pathway in Vibrio vulnificus cytolysin-induced hyperpermeability.

Endothelial hyperpermeability, a hallmark of septicemia, is induced by stress fiber formation, which is primarily regulated by the calcium/calmodulin signaling pathway in endothelial cells. We previously reported that trifluoperazine, a calcium/calmodulin antagonist, blocks Vibrio vulnificus cytolysin (VVC) -induced lethality at in vivo animal model. The object of this study was therefore to examine whether VVC induces stress fiber formation through calcium/calmodulin signaling in endothelial cells.

Introduction to Distribution and Ecology of Sterile Conks of Inonotus obliquus.

Inonotus obliquus is a fungus that causes white heart rot on several broad-leaved species. This fungus forms typical charcoal-black, sterile conks (chaga) or cinder conks on infected stems of the birche (Betula spp). The dark brown pulp of the sterile conk is formed by a pure mycelial mass of fungus.

Chemical Components of Paecilomyces tenuipes (Peck) Samson.

The caterpillar-shaped Chinese medicinal mushroom (DongChongXiaCao) looks like a worm in the winter and like a grass in the summer. The fruiting body has been regarded as popular folk or effective medicines used to treat human diseases such as asthma, bronchial and lung inflammation, and kidney disease. The fruiting bodies of Paecilomyces tenuipes that formed on the living silkworm (Bombyx mori) host were used in this examination.

Seed Germination of Gastrodia elata Using Symbiotic Fungi, Mycena osmundicola.

The germination rate and longevity of seeds of Gastrodia elata Blume have been observed for 48 weeks using Mycena osmundicola strain H-21, one of fungi stimulating seed germination. Storage condition of post-harvest seeds was observed in the different temperature ranges of -30℃, -5℃, 5℃ and 30℃ for 48 weeks. After storage period of 48 weeks, the germination rate of G.

Epigallocatechin gallate prevents autoimmune diabetes induced by multiple low doses of streptozotocin in mice.

Cytokines produced by immune cells infiltrating pancreatic islets have been incriminated as important mediators of beta-cell destruction in insulin-dependent diabetes mellitus. In non insulin-dependent diabetes, cytokines are also associated with impaired beta-cell function in high glucose condition. By the screening of various natural products blocking beta-cell destruction, we have recently found that epigallocatechin gallate (EGCG) can prevent the in vitro destruction of RINm5F cell, an insulinoma cell line, that is induced by cytokines.
