Nile red (also known as Nile blue oxazone) is a lipophilic stain. Nile red stains intracellular lipid droplets yellow. In most polar solvents, Nile red will not fluoresce; however, when in a lipid-rich environment, it can be intensely fluorescent, with varying colors from deep red (for polar membrane lipid) to strong yellow-gold emission (for neutral lipid in intracellular storages).
Nile red (also known as Nile blue oxazone) is formed by boiling Nile blue with sulfuric acid. This produces a mix of Nile red and Nile blue. Nile red is a lipophilic stain; it will accumulate in lipid globules inside cells, staining them red. Nile red can be used with living cells.
Plasticizers in microplastics have been linked to abnormal growth and reproductive problems in multiple animal models due to endocrine disruption. Microplastics have also been postulated to cause GI irritation , alteration of the microbiome , disturbance of energy and lipid metabolism , and oxidative stress .
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
It is estimated that approximately 90% of the plastics in the pelagic marine environment are microplastics. [33] These microplastics are frequently consumed by marine organisms at the base of the food chain, like plankton and fish larvae, which leads to a concentration of ingested plastic up the food chain. Plastics are produced with toxic ...
West Nile virus (WNV) is a mosquito-borne virus first identified in the United States in 1999. It is most commonly found in Africa, Europe, the Middle East and North America.
A diaphonized mirror dory.The bones are dyed red and the cartilage is dyed blue. Diaphonized veiled chameleon. Field Museum of Natural History, Chicago.. Diaphonization (or diaphonisation), also known as clearing and staining, is a staining technique used on animal specimens that first renders the body of the animal transparent by bathing it in trypsin, and then stains the bones and cartilage ...
As mosquito season continues, public health officials in the U.S. have been tracking several different illnesses caused by the pesky flying insect. Health officials are reporting at least eighteen ...
