Treating Male Infertility With Stem Cells

...ellular signals are needed. Future studies will characterize the other factors, such as hormones, required to complete sperm production in this transplant model. In addition, since the bone marrow cells used here represent a mixed population of stem cells, further studies will determine which specific stem cel...

Nicholson, MD, medical director of the Sleep Disorders Center at Pomona Valley Hospital Medical Center in Pomona, Calif., says that more public education needs to be done in order to reach o...

Steroids Cause the Same Tissue Changes as Tendon Injury

... gene array analysis of the complete rat genome to characterize the molecular response of rat rotator cuff tendon tissue to injury, injection of corticosteroids, and the presence of both injury and corticosteroid. Results of the study shows that 2,000 genes were changed by injury; 1,000 genes were changed by st...

...ain it? What are the steps that should be taken to characterize the virus? Who should do it and how long will the laboratory tests take? In the meantime, what should they be doing? Obviously, they have to procure the correct vaccine. Since we do not have the capability to produce the vaccine, we have to go thro...

Tears Reveal Some of Their Deepest Secrets to Researchers

... used other techniques, such as chromatography, to characterize types of lipids in the tear film, but advances in mass spectrometry technology are improving research efforts. “Other scientists used different techniques to try to determine the composition of meibum, but mass spectrometry is sensitive enough to d...

Billions of Dollars Saved in U.S. By Polio Vaccination

Vision Loss Can Be Prevented in People With Diabetes

...s that contribute to the vascular disruptions that characterize diabetic retinopathy. Specifically, they aim to inhibit the growth of new blood vessels or the activity of proteins in the nerve cells of the retina. These treatments hold promise of intervention at earlier, non-sight-threatening stages, but they w...

Pair of MicroRNA Molecules Controls Major Oncogene in Most Common Leukemia

... Pekarsky added. “We have a lot of work to do to characterize these miRNAs because we don’t even know whether they work on transcriptional or translational level,” he said. “But finding that they control this cancer’s major risk factor is a very helpful advance.” The study was funded by the National Institute...

No Proven Programs to Help Teens Quit Smoking

...y are “designed to respond to the many issues that characterize young persons’ smoking.” Even so, the evidence is not strong enough to recommend widespread implementation of any model, the reviewers say, especially considering that there’s no research into whether the approaches prevent teens from smoking again...

Breast Cancer Patients Suffer From Psychological Problems
