Navigable nanotransport

...ceutical agents to their specific target organs or cell types, you need a good carrier: nanoscopic capsules with surface elements that can "recognize" the target in question could do the trick. To date, all methods for the production of such tiny capsules require preorganized structures or "molds" to sha...

Major gene study uncovers secrets of leukemia

...ion of a large number of other genes involved in B cell development. Together these genes coordinate the complex changes needed to induce progenitor cells to differentiate into B lymphocytes. In ALL, the leukemic cells fail to differentiate normally and instead remain blocked at an immature stage of devel...

Researchers learn what sparks plant growth

...which tissue system in plants drives and restricts cell growth. "Our work exposes the presence of cell-...brassinosteroid, the plant restricts growth. Thus, cell signaling began in the epidermis and followed into the inner layers of tissue, directing those cells...

Scripps research study shows humans and plants share common regulatory pathway

...s, cytokine production and apoptosis or programmed cell death. Despite the fact that various models of Nod1 activation have been described, little has been known about other proteins that might affect the protein’s activation. In contrast, a number of additional proteins have been linked to the activation...

Nanotextured implant materials: blending in, not fighting back

...evelop drugs or develop materials that will kill a cell ?no matter if it kills a bad cell or a good cell. We're trying to find materials that accept good cells, as opposed to killing off bad...

Better assessment of transfusions could save blood

...these patients receive a large number of red blood cell (RBC) transfusions in order to restore proper hemoglobin levels. New research shows that alternative treatments may lead to fewer transfusions, conserving critical blood supplies in hospitals. The report is published in Seminars in Dialysis. Phlebo...

Discovery could lead to better control of hemorrhagic fever viruses

...lls, it is found on the surface of virtually every cell of the body. It is abundant on endothelial cells, which line blood vessels, a fact that may help account for the bleeding and organ damage caused by the viruses.
