Role of Bone Marrow Niches In Stem Cells hriving

Hematopoietic stem cells (HSCs) are a class of stem cells located in bone marrow. HSCs give rise to every type of blood cell—from the red blood cells that carry oxygen to the white blood cells of the immune system.

Bone marrow provides a niche that both houses and regulates HSCs to ensure proper formation of blood cells. However, the precise mechanisms that maintain the HSC niche are not fully understood.

A New Microscopy Techniques Studied On Living T Cells

They protect us from the onslaught of bacteria and viruses and also from cancer: T cells are an indispensable part of our immune system. They constantly renew their surface with thousands of highly sensitive T cell antigen receptors, which allow them to identify atypical or foreign molecules (antigens) in our body. If such antigens are detected, for example on virally infected cells or cancer cells, T cells either directly kill these cells or alarm other immune cells to start a full-blown immune response.

Music Is The Greatest Efficiency At reducing Arterial Pressure

Research shows anti-hypertensive drugs improve heart rate more in patients who listen to music after taking medication. Among musical genres, classical music is the one with greatest efficiency at reducing arterial pressure; authors of the study speculate whether music acts on the patients' parasympathetic system, increasing their capability of absorbing medication. The study was published in Scientific Reports.
