To create the ultimate chocolate — smooth, lustrous, and with just the right texture to give a perfect crack when it breaks — you need to encourage the crystal known as Type V to form in larger quantities than the others. The reason for the repeated heating and cooling is to allow ...
Conception is starting with blood cells from female donors and trying to transform these into the first “proof-of-concept human egg” made in the lab. The company hasn’t done it yet—nor has anyone else. There are still scientific puzzles to overcome, but Krisiloff sent out an email...
This study provides the first evidence for the existence of prefusion F-specific antibodies and their dominant contribution to the RSV-neutralizing activity of human sera. Article CAS PubMed PubMed Central Google Scholar Ngwuta, J. O. et al. Prefusion F-specific antibodies determine the ...
Secondly, identify knowledge gaps or limitations in your topic by conducting a preliminaryliterature review. It is possible to later use these gaps to focus your research question after a certain amount of fine-tuning. 3. Narrow your research to determine specific research questions You can focus ...
Recent evidence has elucidated how multipotent blood progenitors transform their identities in the thymus and undergo commitment to become T cells. Together with environmental signals, a core group of transcription factors have essential roles in this process by directly activating and repressing specific ...
However, further studies are needed to determine whether this phenomenon has a measurable effect on immune function. Even though polyamines have been known to affect the intestinal mucosa and various immune functions for decades, surprisingly little is understood of the extent and the mechanisms by ...
We have utilized a murine model of HLH to determine whether normal cytotoxic function in only a fraction of relevant hematopoietic or immune cells may restore normal immune regulation. Perforin deficient (prf-/-) mice were lethally irradiated and reconstituted with bone marrow from either wild type...
In these cases, the type of catheter can be changed to see if it is possible to reach the uterus more easily. Once the embryo transfer has been carried out, the patient rests for 20-30 minutes. Afterward, the woman can return home leading a normal life, but without excessive physical ...
VSMCs phenotype switching is a critical response to vascular injury stimulus. During this process, VSCs located in adventitia and media also undergo reprogramming and migrate to the intima, cooperating with the VSMCs-derived cells to promote disease. Therefore, the primary goal is to determine th...
