Bioelectricity - Engineering Unexcitable Cells To Be Electrically Excitable

in medicine, biology

Duke University bioengineers have turned normally "unexcitable" cells into cells capable of generating and passing electrical current, or  bioelectricity.  This development has major implications in the treatment of health conditions such as heart attack.

Lead Poisoning Associated with Traditional Medicines

in environment, medicine, biology

It is not pleasant to discover that some medicines may contain poison.  Lead has been implicated in poisoning associated with lead containing paint, lead-contaminated dust in older buildings, and contaminated water and soil; but many people may not know that some medicines may also contain lead.

in environment, medicine, biology

Like a chain reaction, 23 of the 65 titi monkeys housed in a building in California Primate Research Center came down with a severe infection and 19 died.  Three humans also fell sick. This deadly outbreak of fulminant pneumonia and hepatitis occurred in the closed colony of New World titi monkeys in May 2009.

Aging and repeated injury do not prevent tissue regeneration - a study with newts

in medicine, biology

Can repeated injury prevent regeneration of tissues?  A new study shows that age and repeated injury do not adversely influence tissue regeneration.  The studies were done in newt, a vertebrate species with extraordinary regenerative capacity.

A synthetic windpipe, seeded with patient's own stem cells, was successfully transplanted in a patient with tracheal cancer by physicians in Sweden. According to the hospital, the transplanted patient was recovering without the use of immunosuppressive drugs.

Acid Reflux, What Is It?

in medicine, biology

Acid reflex is caused when stomach acid enters the food pipe.  When we eat food, it goes through food pipe, also known as esophagus, and enters stomach. Stomach acid helps in digestion of the food.  When stomach contents, including stomach acid, leak  backwards into the food pipe, it causes acid reflux.
