First discovered in 1957 by Crane et al. [1], its chemical structure was determined by Karl Folkers [2], who later won the Priestley medal from the American Chemical Society. This oil-soluble, vitamin-like micronutrient forms part of the electron transport chain which, in the process of… Continue reading Coenzyme Q10

“Crystal-clear” method distinguishes between glass and fluids
The colloids that were used for the model: particles, each with a diameter of approximately 150 nm, suspended in water. The solid nucleus consists of the plastic polystyrene, the surrounding shell of a thermosensitive poly(N-isopropyl-acrylamide) network. By lowering the temperature, each individual particle’s volume—and, by definition, its packing density—can be increased. Photo: HZB/M. Siebenbürger Many… Continue reading “Crystal-clear” method distinguishes between glass and fluids
Fluoride’s Unexpected Role In Photocatalysis-Materials: Acid’s surface residue, not just the catalyst, should get credit
Using HF in TiO2 synthesis (left) changes the crystals’ morphologies and facets relative to an HF-free method (right), as seen in these TEM images, and may unexpectedly alter the crystals’ catalytic properties.

Immunosuppressant Drug Rapamycin Helps Preserving Female Fertility
Sirolimus (INN/USAN), also known as rapamycin, is an immunosuppressant drug used to prevent rejection in organ transplantation; it is especially useful in kidneytransplants. It prevents activation of T cells and B cells by inhibiting their response tointerleukin-2 (IL-2). A macrolide, sirolimus was discovered by Brazilian researchers as a product of the bacterium Streptomyces hygroscopicus in a soil sample from Easter Island[1] — an island also known as Rapa Nui.[2] It was approved by the… Continue reading Immunosuppressant Drug Rapamycin Helps Preserving Female Fertility
AT13148, Drug Blocks Multiple Cancer Causes
AT13148 AT13148 is a multi-AGC kinase, ATP-competitive inhibitor, identified utilizing high-throughput X-ray crystallography and fragment-based lead discovery techniques. AT13148 caused substantial blockade of AKT, p70S6K, PKA, ROCK and SGK substrate phosphorylation and induction of apoptosis in both a concentration and time-dependent manner in cancer cells with clinically relevant genetic defects both in vitro and in… Continue reading AT13148, Drug Blocks Multiple Cancer Causes
