A study by the NIH found that ACE inhibitors and beta blockers significantly reduced kidney failure risk compared to calcium channel blockers. High blood pressure management has improved stroke and heart disease risks, but kidney failure remains a concern for African Americans.
Researchers at the University of Michigan have discovered a powerful new antibiotic candidate, PD 404182, which is 10,000 times more effective than other known inhibitors of a key enzyme in Gram-negative bacteria. The compound targets KDO 8-P synthase, essential for bacterial cell surface formation, and shows promise in weakening bacte...
Researchers discover that nerve cells use chemical scissors to clip off axon guidance receptors, controlling their navigation in the nervous system. Metalloprotease inhibitors enhance netrin activity by blocking receptor cleavage.
A UI-led study found that flavopiridol, a cancer treatment, blocks HIV-1 replication in cell culture experiments at very low concentrations. This suggests the drug may have anti-HIV properties and could be a potential treatment for AIDS.
Researchers developed an experimental drug that reversed the effects of Fabry disease in mice, reducing glycolipid levels and eliminating toxic side effects. The treatment has potential applications for other lysosomal storage diseases affecting thousands of people in the US.
