Selenite has been a top favourite for many crystal lovers dating back to the Ancient Greeks who named the translucent crystal Selenite which means "moon" in Greek. They even constructed windows out of Selenite to allow light into darker rooms. Selenite is commonly found in the deep caves of Mexico, Morocco and Madagascar and the raw crystal formations …

(K) PBS or selenite (Se)-treated Th1 cells were cultured in serine-free medium for 6 h and then incubated with 13 C-serine for 24 h. LC-MS was performed for 13 C-labeled metabolic production. (L and M) Several folate metabolic inhibitors were added to Th1 cell-polarizing cells. Flow cytometry of intracellular staining for IFN-γ was performed (L).
The oxyanions selenate and selenite are the important and common bioavailable species and incidentally the most toxic. In general, selenate is the most bioavailable species taken up from soils and accumulates largely untransformed in the shoot tissue of plants, whereas selenite is often transformed into organic species but less likely to be ...
Flow cytometry was used to evaluate cell apoptosis. Fura-2AM was used to calculate intracellular Ca 2+ concentration. Sodium selenite could ameliorate hydrogen peroxide (H 2 O 2)-induced cell apoptosis and improve expression levels of glutathione peroxidase and thioredoxin reductase. Pretreatment with sodium selenite improved SOD activity and ...
The SeNPs were obtained using A. brasilense Sp7 incubated with selenite. Grinding of the biomass samples was shown to result in slight downshifting of …
Fireworks Obsidian Slabs from Mexico. Obsidian is volcanic glass. It often has flow lines and transparent areas that create interesting effects. Obsidian has a reputation for being difficult to polish, usually because too coarse a grit can create fairly deep fracture zones that won't come out when the stone is cut at finer grits.

Abrasive suspension flow machining (ASFM) is an advanced finishing method that uses an abrasive suspension slurry for grinding and chamfering as well as the finishing of inaccessible components. This study examines the effect of back pressure on the grinding characteristics of an abrasive suspension flow during the grinding of slender holes. A …
Selenite is found in cracks and cavities in rocks. Good crystals have been collected at Gyp Hill, a salt dome southeast of Falfurrias in Brooks County, and some selenite has been mined there. Selenite crystals also occur scattered through clays, particularly along creek banks, in Lee, Fayette, Bastrop, and several other counties.
