Study: Sickle cell trait does not increase heart disease risk in African Americans

Study: Sickle cell trait does not increase heart disease risk in African Americans

Health
Jan. 5 (UPI) -- Carrying the sickle cell trait does not play a significant role in the increased risk for coronary heart disease among African Americans, a study published Tuesday by JAMA Network Open found. Although African Americans are twice as likely to die from heart disease than White people, according to the U.S. Centers for Disease Control and Prevention, those carrying the sickle cell trait have only a 3% higher risk for heart problems than those who don't, the new data showed. Advertisement It's likely that other health problems, such as higher rates of high blood pressure and diabetes, contribute more to heart disease risk among African Americans than sickle cell, the researchers said. "We don't see sickle cell trait as significant risk factor by itself," study co-author Dr. Hy...

Study reveals the secrets of cell size control

Study reveals the secrets of cell size control

Science
May 17 (UPI) -- New research has revealed the mechanism cells use to control their growth and maintain their size, a phenomenon known as "cell size homeostasis." "Cell size homeostasis is a fundamental biological question and to our knowledge this is the first time we finally understand its mechanistic origin," Suckjoon Jun, a biophysicist at the University of California, San Diego, said in a news release. Jun and his colleagues previously showed that cell size is controlled by something called the "adder principle." The researchers showed cells grow by a fixed added size, irrespective of their birth size. The adder principle proved cells don't control growth through a sense time and space, but it failed to explain the exact mechanisms that allows for size homeostasis. The latest resear...
UK patient 'free' of HIV after stem cell treatment

UK patient 'free' of HIV after stem cell treatment

Health
A UK patient's HIV has become "undetectable" following a stem cell transplant - in only the second case of its kind, doctors report in Nature.The London patient, who was being treated for cancer, has now been in remission from HIV for 18 months and is no longer taking HIV drugs.The researchers say it's too early to say the patient is "cured" of HIV.Experts say the approach is not practical for treating most people with HIV but may one day help find a cure.The male London patient, who has not been named, was diagnosed with HIV in 2003 and advanced Hodgkin's lymphoma in 2012. He had chemotherapy to treat the Hodgkin's cancer and, in addition, stem cells were implanted into the patient from a donor resistant to HIV, leading to both ...
