Immunologists have shown that a drug used to fight arthritis also stops the process that allows the tuberculosis bacillus to infect and hijack blood stem cells.
Read morePeople with high blood pressure who take all their anti-hypertensive medication in one go at bedtime have better controlled blood pressure and a significantly lower risk of death or illness caused by heart or blood vessel problems, compared to those who take their medication in the morning, according to new research.
Read morePatients who survive a cerebral hemorrhage may suffer delayed severe brain damage caused by free hemoglobin, which comes from red blood cells and damages neurons. Researchers have now discovered a protective protein in the body called haptoglobin, which prevents this effect.
Read moreToday's standard process for administering gene therapy is expensive and time-consuming — a result of the many steps required to deliver the healthy genes into the patients' blood stem cells to correct a genetic problem. Scientists believe they have found a way to sidestep some of the current difficulties, resulting in a more efficient gene delivery method that would save money and improve treatment outcomes.
Read moreTracking lead levels in soil over time is critical for cities to determine lead contamination risks for their youngest and most vulnerable residents, according to a new study.
Read moreMealtimes can become a difficult experience for individuals with diabetes. After a meal, blood sugar levels may soar as the food digests or unexpectedly plummet if an insulin dose was more than the meal required.

The 2019 Nobel Prize in Physiology or Medicine is being awarded jointly to William G. Kaelin Jr., Sir Peter J. Ratcliffe and Gregg L. Semenza for identifying molecular machinery that regulates the activity of genes in response to varying levels of oxygen.
Over half of people prescribed the targeted blood cancer-fighting drug ibrutinib developed new or worsened high blood pressure within six months of starting the medication. The analysis is also the first to tie ibrutinib-related hypertension to a heightened risk of heart problems, particularly atrial fibrillation. Moreover, the association of ibrutinib with cardiovascular complications remained regardless of the prescribed dose.
Read moreFor the first time ever, a professor has observed a crystallized iron product called hemozoin being made in mammals, with widespread implications for future research and treatment of blood disorders. Findings could be used to treat sickle cell disease and malaria patients, while opening up diverse research avenues across immunology, parasitology, neuroscience, microbiology, and even urology.
Read moreThe complex interplay among the arteriovenous grafts, the vessels they connect, and the blood they transport has been difficult to simulate, but one new method provides a way. Researchers report simulations that reconstructed the fluid dynamics affected by the insertion of an AVG. They used a model that considered the ability of AVG tubes and blood vessels to deform and found much of the disrupted flow could be mitigated by this flexibility.
