A new aggressive form of HIV can progress to AIDS in just three years - so rapidly that patients may not even realise they were infected, scientists say. Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV. Once inside a host, these strains can recombine into a new variant of the virus, researchers said.
About three years ago, Betty Vaughn of Golden Valley, Minn., started to feel light-headed, fatigued and out of breath when she walked up and down the stairs. After visiting her doctor, the 89-year-old was diagnosed with degenerative mitral regurgitation (DMR), a heart condition in which the leaflets of the mitral valve do not close completely, causing blood to flow backward and leak into the left atrium of the heart.
The appearance of infectious diseases in new places and new hosts, such as West Nile virus and Ebola, is a predictable result of climate change, scientists say. Humans can expect more such illnesses to emerge in the future, as climate change shifts habitats and brings wildlife, crops, livestock, and humans into contact with pathogens to which they are susceptible but to which they have never been exposed before, researchers said.
Researchers have developed a "fever alarm armband," a flexible, self-powered wearable device that sounds an alarm if you are running a high body temperature. The device developed at the University of Tokyo combines a flexible amorphous silicon solar panel, piezoelectric speaker, temperature sensor, and power supply circuit create with organic components in a flexible, wearable package.
An experimental drug may help treat patients with hormone-resistant breast cancer, scientists say. Palbociclib, an investigational oral medication that works by blocking molecules responsible for cancer cell growth, is well tolerated and extends progression-free survival (PFS) in newly diagnosed, advanced breast cancer patients, including those whose disease has stopped responding to traditional endocrine treatments, researchers said.
Our taste cells regenerate about every 10 days, much like skin cells, scientists say.A person who loses their hearing may never get it back. It is also likely that they won't get back any brain cells they may have burned out.
Mylan N.V. and Mylan Inc. announced the U.S. launch of Buprenorphine Hydrochloride Sublingual Tablets (2 mg and 8 mg) and Disulfiram Tablets USP (250 mg and 500 mg) which are the generic versions of Reckitt Benckiser's Subutex® Sublingual Tablets and Odyssey Pharmaceutical's Antabuse® respectively.
In a remarkable medical feat, neurologist Dr. Naeem Sadiq has successfully treated a patient suffering from Parkinson's disease (PD) for the last 12 years by using stem cell therapy. 59 years old Ashok Kumar, who couldn't talk, walk, sit or eat due to the tremors and rigidity is now doing all these activities without any support, much to the astonishment of his family. Just two doses of stem cell transplant in a span of four months helped Kumar to recover.
Vitamin D is amongst very important component for human growth. And changes in blood level of vitamin D should not be good for health. Researchers from University of Copenhagen are the first in the world to show that there is a connection between high levels of vitamin D and cardiovascular deaths.
Japanese researchers have found that a substance in black tea may be effective for treating osteoporosis, a disease that causes bones to become weak and brittle.
