Grifola gargal is a medicinal mushroom with biological effects, such as antiatherogenic activity, and is used as a treatment for various chronic inflammatory diseases. The aim of this study is to investigate the antidiabetic and antiobesity effects of a low-molecular weight hot water extract from G. gargal (GGL) against diabetes type 2.

A novel compound, -4-ethoxy-2-hydroxy-4-oxobutanoic acid (), and six known compounds (-) were isolated from the fruiting bodies of the wild edible mushroom . The planar structure of was determined by the interpretation of spectroscopic data analysis. The absolute configuration of was determined by comparing specific rotation of the synthetic compounds.

A clinical study was performed to examine the effect of the edible mushroom, Grifola gargal, on bone turnover markers and serum lipids in middle-aged and elderly Japanese women. Postmenopausal women aged 51-73 years (mean age, 61 years) received daily oral administration of 5 g G. gargal fruiting bodies (hot air-dried and powdered; G.

Myeloperoxidase (MPO)-generated halogenating molecules, such as hypochlorous acid and hypobromous acid (HOBr), in inflammatory regions are postulated to contribute to disease progression. In this study, we showed that ergothioneine (EGT), derived from an edible mushroom, inhibited MPO activity as well as the formation of 8-bromo-2'-deoxyguanosine in vitro. The HOBr scavenging effect of EGT is higher than those of ascorbic acid and glutathione.

The two reasons that patients desire buttonhole cannulation are avoidance of puncture pain and extension of arteriovenous fistula life. Despite the desire to receive buttonhole cannulation by many patients, medical staff at most local hemodialysis facilities tend to hesitate to implement the cannulation method. This method is used on patients in the dialysis unit at Saitama Medical Center, but tends to be discontinued for those patients upon their transfer to local hemodialysis facilities.

Background: Previous studies have demonstrated the beneficial activity of activated protein C in allergic diseases including bronchial asthma and rhinitis. However, the exact mechanism of action of activated protein C in allergies is unclear. In this study, we hypothesized that pharmacological doses of activated protein C can modulate allergic inflammation by inhibiting dendritic cells.

The beneficial effects of edible mushrooms for improving chronic intractable diseases have been documented. However, the antiatherogenic activity of the new medicinal mushroom Grifola gargal is unknown. Therefore, we evaluated whether Grifola gargal can prevent or delay the progression of atherosclerosis.

Article Synopsis
  • Epithelial to mesenchymal transition (EMT) is linked to airway remodeling in asthma, and eosinophils play a significant role in this process.
  • Montelukast, a cysteinyl leukotriene receptor antagonist, was tested for its ability to reduce EMT effects caused by eosinophils.
  • Results showed that montelukast inhibited harmful changes in airway epithelial cells, decreased specific protein expressions associated with EMT, and mitigated the production of promoting factors like TGF-β1 and CysLTs, indicating its potential in managing asthma-related airway remodeling.

Five fatty acid amides, termitomycamides A to E (1 to 5), were isolated from the giant edible mushroom Termitomyces titanicus. The structures of 1-5 were determined by the interpretation of spectral data and/or synthesis. Compounds 2 and 5 showed protective activity against endoplasmic reticulum stress-dependent cell death.

This study examined interactive processes that occurred in video-mediated referential communication task. Pairs of participants were assigned to one of four conditions; in a room with partition, or in separate rooms linked by telephone with three levels of noise interference (none, low, and high). In all conditions, a video-monitor link allowed the participants to see the upper body of their partner.
