In the microwave-radiofrequency spectrum, Wi-Fi is a short-range wireless broadband technology, which transmits at frequency of 2.5 GHz. This type technology has been positioned itself as one most widely used technological advances in recent years. It reported that direct exposition to radiofrequencies can induce physiological changes different animals and plants species. One degenerative effec...

Abstract Foods and beverages are nutrient-rich systems prone to a rapid development of microorganisms that hamper their long-period storage. Particularly, yeasts strong fermenters fresh processed fruits vegetables; hence, they often accountable for spoilage production off-flavor. This work provides quick easy tool recognize count the juices with ergosterol as distinctive biomarker molds yeasts....

The inactivation of ERG3, a gene encoding sterol Δ⁵,⁶-desaturase (essential for ergosterol biosynthesis), is a known mechanism of in vitro resistance to azole antifungal drugs in the human pathogen Candida albicans. ERG3 inactivation typically results in loss of filamentation and attenuated virulence in animal models of disseminated candidiasis. In this work, we identified a C. albicans clinica...

The last unidentified gene encoding an enzyme involved in ergosterol biosynthesis in Saccharomyces cerevisiae has been cloned. This gene, designated ERG27, encodes the 3-keto sterol reductase, which, in concert with the C-4 sterol methyloxidase (ERG25) and the C-3 sterol dehydrogenase (ERG26), catalyzes the sequential removal of the two methyl groups at the sterol C-4 position. We developed a s...

THE study of the antirachitic activity induced in various sterols by irradiation, which led to the discovery of ergosterol as the most potent source of vitamin D [Rosenheim and Webster, 1926; 1927, 1], has subsequently brought to light an interesting relationship between chemical structure and potential biological activity. The most characteristic general features of the sterol structure are th...
