For example, levels of PCB's and other industrial chemicals appear to be declining in studied polar bear populations, as in this new paper.
For example, levels of isoprene and acetone rose during two particularly intense scenes in the Hunger Games.
For example, levels of maternal testosterone are hypothesised to cause high-achieving women to give birth to more sons [23], [28].
For example, levels of IL-1ß and IL-6, but not TNF-α, were significantly elevated in subjects in labor when compared to those not in labor [30].
For example, levels of Bifidobacterium significantly and positively correlated with improved glucose-tolerance and low-grade inflammation in prebiotic treated-mice [1], [6].
For example, levels of Bifidobacterium adolescentis and Parabacteroides distasonis were remarkably stable in fecal samples in baseline and washout samples, and their populations returned to baseline level within one week after RS administration was stopped.
There is a wide variation in TGF-β levels within and between populations, for example levels of duodenal TGF-β+cells in rural Gambian infants are up to ten times higher than in UK controls [42].
For example, levels of glutathione (GSH), one of the most important cellular antioxidant defense mechanisms, decline during aging in humans and mice, accompanied by various age-related pathologies [26], [27], [28], [29].
For example levels of mRNA may increase after 20 60 min following the treatment but the protein synthesis could be further delayed, and statistically significant change in protein concentrations will take much longer to develop and have smaller ratios.
For example, levels of 1-Ins P7 are elevated during nutrient stress in yeast [ 7].
