They are diurnal, hunting during the day, and are known to move, looping end over end, or contract, in response to light. New research published in BioMed…
Plants serve as the conduit of energy into the biosphere, provide food and materials used by humans, and they shape our environment. According to Ehrhardt and…
They show extremely high gene transfer efficiency and afterwards enable the quick and simple separation of the transfected cells from the transfection pool. A…
The placental niche, a stem cell “safe zone,” supports blood stem cell generation and expansion without promoting differentiation into mature blood cells,…
The study proposed a new model to explain how mammalian cells establish the sense of direction necessary to move, as well as the mechanism that a…
Their report on the new NOSH-aspirin, so named because it releases nitric oxide (NO) and hydrogen sulfide (H2S), appears in the journal ACS Medicinal Chemistry…
The winter sun feels welcome, but not so a summer sunburn. Research over the past 20 years has shown that proteins on the surface of nerve cells enable the…
The study, in which mice were bred to make a supercharged version of the protein focal adhesion kinase, or FAK, appeared March 1 in the online edition of the…
Three of the genes are particularly intriguing because they code for proteins similar to those known to regulate mammalian embryonic stem cells. Such genetic…
Even in the early stages of cancer, individual cancer cells can be found in the blood. Certain subsets of these circulating tumor cells can cause metastasis. In cases of breast cancer, it is known that these cells can differ from the original tumor cells, which allows them to survive treatment to cause later recurrence. It could thus be quite informative to detect these cells in the blood and examine them more closely. In the journal Angewandte Chemie, researchers at the University of Washington (Seattle, USA) describe a new chip-based method that allows for the detection and isolation of tiny concentrations of such cells in blood. …
The work focused on sulfa drugs and their target enzyme, dihydropteroate synthase (DHPS). Most disease-causing microorganisms need DHPS to help make the…
In animal experiments on both simple organisms like fruit flies and in more complex animals like mice, researchers have seen that stimulating autophagy leads…
Thus, they have been extensively investigated during the last decade. Natural biomacromolecules such as bovine serum albumin (BSA) have conventionally been…
