Spaceflight

Effects Of Spaceflight On Heart Cell

During space travel, exposure to microgravity may have a profound influence on the physiological function of mammalian cells. In this study, they took the opportunity of the Tianzhou-1 (TZ-1); mission to investigate how spaceflight may affect cardiac differentiation of induced pluripotent stem cells (iPSCs). A bioreactor was engineered to perform cell culturing and the time-lapse…

Key Mechanism: Linked To Healthy Development

An R-loop is a three-stranded nucleic acid structure; composed of a DNA:RNA hybrid and the associated non-template single-stranded DNA. R-loops may have formtaion in a variety of circumstances, and may be tolerated or cleared by cellular components. The term “R-loop” was given to reflect the similarity of these structures to D-loops; the “R” in this case…

The findings; published in the open-access journal eLife; suggest that the common practice of training beyond fatigue should have reconsideration as it could do more harm than good. The saying goes that…

Fluconazole: Fungi Sexually Active

The yeast Candida albicans occurs in most healthy people as a harmless colonizer in the digestive tract. However, it can also cause life-threatening infections, especially in immunocompromised patients. These infections are usually treated with the drug fluconazole, which inhibits the synthesis of ergosterol in Candida. Ergosterol fulfils similar important functions in fungi as cholesterol in humans.…
