be beneficial in inflammatory diseases where glucocorticosteroids have proved to be ineffective, such as COPD, steroid-resistant asthma, and arthritis. These compounds may provide candidate molecules for the development of novel anti-inflammatory the...
UCLA and Univ. of Utah researchers identify how a hormone regulates iron
...rugs to block hepcidin from binding to ferroportin might
help release more iron into the body. Hemochromatosis is the most common genetic disease in the United States according to the Centers for Disease Control. One in 100-200 people have a double mutation of a gene that puts them at risk for developing ...
Diabetic damage to eyes, heart, nerves, kidneys may be explained by controversial theory
...the potential to produce much more damage than you might
expect if you looked at either one independently," Williamson explains. Scientists have known for some time that diabetes increases transformation of NAD to NADH by boosting cells' consumption of glucose through a process known as the sorbit...
Scientists closing in on nerve proteins' contributions to memory and hearing loss
...ientists have begun amassing evidence that Nrg-ICD might
be as important or even more important than Nrg-ECD. "In a comparison of the frog and human genes, we earlier showed that Nrg-ICD was 87 percent identical between the two species," says Bao, who is first author of the new study. "When part of a pr...
Is the zebra fish leading us to new therapies?

perhaps use the same signals as nerve cells. To answer this question, the researchers called on the small, translucid zebra fish. The great advantages of using zebra fish instead of mice are that zebra fish grow and multiply very rapidly and - becau...
Stress impairs thinking via mania-linked enzyme
...Since PKC inhibitors could act more directly, they might
quench symptoms more quickly. Patients could carry PKC inhibitors and take them preventively, as soon as they sense a manic episode coming on." Clinical trials of a PKC inhibitor, the anti-cancer drug tamoxifen, are currently underway in bipolar diso...
