semen could transfer motional energy to sperm cells, improving their motility. It, in turn, causes a reorganization of the initial soot agglomerates. The findings suggest that potential alterations in the biochemistry of human semen due to soot exposure may contribute to the observed acceleration or...
An interesting clue to the mechanisms behind neutralization resistance of cell-associated HIV is that deletion of the CT of Env does diminish the magnitude of resistance, ie, becomes easier to neutralize (Durham et al., 2012). Since the Env CT plays an important role in controlling fusion duri...
It was he, not I, who lived in the blaze.I had fallen victim to the fallacy of the “growing edge;” the belief that only the very frontier of scientific advance counted; that everything that had been left behind by that advance was faded and dead.But is that true? Because a tree ...
On the occasion of Semenza’s retractions, Kaelinsaidin summer 2023: “These papers that are being retracted now are from a different era and different area of biology,” Professor Kaelin toldTimes Higher Education. “It’s an unhappy situation, but at least none of the work that led to ...
There is a couple ways that DNA left behind can be tested to solve a crime. Either if the suspect has been caught and or had his or her DNA tested, or if he or she has left behind any biological evidence. Which then needs to be tested to see if it matches the DNA found in the...
has lagged behind that in other parts of the world. In the South East Asia (SEA) region, basic information on levels of contamination is very limited and, as a consequence, the risk to human and ecological health remains hard to assess. This review synthesises what is currently known about...
Still now, we do not know the reason why it happens or the molecular processes behind it. And the duration of egg-retention in some blow flies also varies according to different nutritional states, such as protein starving. How to use this biological information in forensic fly practices still...
Hou et al. [34] investigated the anti-tumor mechanism of GJXLT and they found that A549 cell growth was inhibited, and apoptosis was induced by GJXLT, which is a formula containing Semen Coicis, Gecko, Stemona, Corium Bufonis, Ginseng, Fritillaria thunbergii Miq, Arisaema consanguineum, and...
Elephants, fossil and modern, have a highly specialized dentition with six cheek teeth on either side of the jaw. At any one time, one to two teeth are exposed in the jaw. As these teeth wear down, they are replaced by a tooth erupting from behind the current tooth. This pattern of ...
compared gene expression in boys with UDT and high risk of infertility (HIR), defined as those with no Ad spermatogonia, to that of boys with UDT and low risk of infertility (LIR), defined as having more than 0.1 Ad spermatogonia per tubule, to elucidate the genetic mechanism behind ...
