Pharmacology is the study of how chemical substances interact with living systems. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties, interactions, toxicology, therapy, and medical applications and antipathogenic capabilities.
'Mini heart' invented to aid blood flow through venous segments

'Mini heart' invented to aid blood flow through venous segments

George Washington University researcher Narine Sarvazyan, Ph.D., has invented a new organ to help return blood flow from veins lacking functional valves. A rhythmically contracting cuff made of cardiac muscle cells surrounds the vein acting as a 'mini heart' to aid blood flow through venous segments. The cuff can be made of a patient's own adult stem cells, eliminating the chance of implant rejection. [More]

Radiation therapy fights cancer in more ways than one

Radiation therapy fights cancer in more ways than one

Radiation therapy fights cancer in more ways than one. Not only does it force cancer cells to self-destruct, but several studies demonstrate that it also activates the immune system to attack tumor cells. [More]
Protein known to promote cancer appears to give blood vessels strength and shape, researchers report

Protein known to promote cancer appears to give blood vessels strength and shape, researchers report

A protein known to promote cancer appears to give the blood vessels strength and shape, researchers report. When yes-associated protein, or YAP, is deleted from vascular smooth muscle cells during development, the protein makes thin-walled blood vessels that over-dilate in response to the usual pressure of blood flow, said Dr. Jiliang Zhou, vascular biologist at the Medical College of Georgia at Georgia Regents University.

Researchers use retro approach to produce new drugs

Researchers use retro approach to produce new drugs

This alternative approach to creating artificial organic molecules, called bioretrosynthesis, was first proposed four years ago by Brian Bachmann, associate professor of chemistry at Vanderbilt University. Now Bachmann and a team of collaborators report that they have succeeded in using the method to produce the HIV drug didanosine. [More]
Diabetes drug reduces amyloid-beta peptides, improves memory in experimental AD models

Diabetes drug reduces amyloid-beta peptides, improves memory in experimental AD models

Researchers from Boston University School of Medicine have found that the diabetic drug, pramlintide, reduces amyloid-beta peptides, a major component of Alzheimer's disease (AD) in the brain and improves learning and memory in two experimental AD models. [More]
Drug and alcohol abuse could be linked with poor development of "love hormone"

Drug and alcohol abuse could be linked with poor development of "love hormone"

Addictive behavior such as drug and alcohol abuse could be associated with poor development of the so-called "love hormone" system in our bodies during early childhood, according to researchers at the University of Adelaide. [More]
