UCLA researchers reprogram normal tissue cells into embryonic stem cells

... skin cells, for example, could be reprogrammed to become embryonic stem cells. Those embryonic stem cells could then be prodded into becoming various cells types beta islet cells to treat diabetes, hematopoetic cells to create a new blood supply for a leukemia patient, motor neuron cells to treat Parkinso...

Bigger horns equal better genes

...er time. Therefore, differences in genetic quality become more apparent as an organism ages. Coltman noted that his study, which incorporated genetic samples from more than 150 ibex, took into account the fact that environmental factors also play a role in determining ibex horn size. The ibex's horns a...

Nitrate in Lake Superior: On the rise

Breakthrough for treatment of fatal heart condition

... with cardiac hypertrophy these levels increase to become abnormally high. Dr Ooi has found that an increase in a third protein in the body, known as REST, can halt the rise of the proteins causing cardiac hypertrophy, which, for the first time, offers an approach to treating the cause of heart hypertrop...

3-D fusion: A better way to image heart disease

...the arteries that supply blood to the heart muscle become hardened and narrowed, explained Santana. The arteries harden and narrow due to buildup of a material called plaque on their inner walls. As the plaque increases in size, the insides of the coronary arteries get narrower and less blood can flow throu...

Fusing imaging technologies creates 'synergy,' helps diagnose heart disease accurately

...the arteries that supply blood to the heart muscle become hardened and narrowed, said Slomka. The arteries harden and narrow due to buildup of a material called plaque on their inner walls. Over time, blood flow to the heart muscle is reduced, and, because blood carries much-needed oxygen, the heart muscle ...
