Remarkable similarity between embryonic and induced pluripotent stem cells - a UW proteomic study

in medicine, biology, omics

In a new study published in Nature Methods, researchers at the University of Wisconsin-Madison report the first full measurement of the proteins made by human embryonic and induced pluripotent stem cells.

Nitrated amyloid enhances plaque formation in Alzheimer’s disease

in medicine

A group of scientists from Germany now reports that inflammation induced modification of the amyloid protein triggers plaque formation and postulate that this mechanism may be critical in Alzheimer's disease pathogenesis.

Hair Growth Signal Dictated by Fat Cells - Hope for the Bald

in medicine, biology

Can baldness be cured?  Yale researchers say that the trick is in getting fat cell (adipocyte) precursors under the skin to talk to stem cells at the base of the hair follicles.  The discovery of the source of signals that trigger hair growth may lead to new treatments for baldness.

Transfusion of Cell Culture-Generated Red Blood Cells - Blood Banks to go Obsolete?

in technology, medicine

A new study indicates that a day may come when we will not need a blood bank!  A research group in France has successfully generated red blood cells from stem cells and injected back to the same individual. This awesome  achievement demonstrates the clinical feasibility of a stem cell-based alternative to donor blood derived red blood cells. 

Fighting cancer with implanted oxygen electrode - a nano leap

in technology, medicine

Solid tumors are hard to kill.  Researchers have now developed miniature devices that can be implanted in tumors to generate oxygen, boosting the killing power of radiation and chemotherapy.

Matching Images of Brain Activity with Complex Thought

in technology, medicine, biology

Can you get a text output of your thoughts? Princeton scientists show that it is possible to generate text about the mental content reflected in brain images. Recent work has shown that it is possible to take brain images acquired during viewing of a scene and reconstruct an approximation of the scene from those images. 

Omega-3 and Omega-6 Fatty Acids in the Diet Can Alter Offspring Sex Ratio - Grain for Girls, Fish for Boys?

in environment, medicine, biology

Can maternal diet influence offspring sex ratio?  According to a research report from New South Wales (Australia) Department of Primary Industries, ratio of omega-6 to omega-3 fatty acids in the diet of mother has a profound effect on offspring sex ratio. 

Sutureless Method for Joining Blood Vessels - A Surgical Revolution?

in technology, medicine, biology

A Stanford University surgical research team used a poloxamer gel and bioadhesive rather than a needle and thread to join together blood vessels, a procedure called vascular anastomosis.  An anastomosis is the technique by which two hollow body structures, such as blood vessels, are joined together.
