Laboratory tests conducted at National Jewish Medical and Research Center indicate that patient Andrew Speaker?s tuberculosis is susceptible to some of the medications previously thought ineffective against his disease.
Researchers in Slovakia have been able to derive mesenchymal stem cells from human adipose, or fat, tissue and engineer them into ?suicide genes? that seek out and destroy tumors like tiny homing missiles.
We?ve all wondered how a seemingly healthy person can actually be at high risk for heart disease or a heart attack. Now researchers have uncovered a new clue to this mystery. The culprit: myeloperoxidase (MPO), a protein secreted by white blood cells that both signals inflammation and releases a bleach-like substance that damages the cardiovascular system.
A new computerised screening test for cervical cancer detects more abnormalities than the traditional smear test, according to a study published on bmj.com today.
An international team of investigators has identified the first human antibodies that can neutralize different strains of virus responsible for outbreaks of severe acute respiratory syndrome (SARS). The researchers used a mouse model and in vitro assays (lab tests) to test the neutralizing activity of the antibodies.
People who have high cholesterol levels may be much more susceptible to a particular disease transmitted by the bites of ticks, a new study in mice suggests.
The first baby to be created from an egg that had been matured in the laboratory, frozen, thawed and then fertilized, has been born in Canada. Three other women are pregnant by the same process. The research was presented to the 23rd annual meeting of the European Society of Human Reproduction and Embryology on Monday, July 2.
Evidence gathered from time-lapse recordings of the formation of early embryos (blastocysts) in the laboratory has revealed why embryos created via IVF and undergoing extended culture are more likely to develop into twins than those created via natural conception. Furthermore, the research has shown that the culture in which the IVF embryos are formed is possibly responsible for the embryos dividing into twins.
A team of biomedical engineers at Virginia Tech and the University of California at Berkeley has developed a new minimally invasive method of treating cancer, and they anticipate clinical trials on individuals with prostate cancer will begin soon.
In what they call a “stunning research advance,” investigators at Georgetown University Medical Center have been able to use simple, nontoxic chemical injections to add and remove fat in targeted areas on the bodies of laboratory animals. They say the discovery, published online in Nature Medicine on July 1, could revolutionize human cosmetic and reconstructive plastic surgery and treatment of diseases associated with human obesity.
