| New combination drug therapy proves very effective in hepatitis C treatments Posted: 12 Apr 2014 11:58 AM PDT Treatment options for the 170 million people worldwide with chronic Hepatitis C Virus (HCV) are evolving rapidly, although the available regimens often come with significant side effects. Two multi-center clinical trials show promise for a new option that could help lead to both an increase in patients cured with a much more simple and tolerable all oral therapy. |
| Hepatitis C treatment cures over 90 percent of patients with cirrhosis Posted: 12 Apr 2014 06:34 AM PDT Twelve weeks of an investigational oral therapy cured hepatitis C infection in more than 90 percent of patients with liver cirrhosis and was well tolerated by these patients, according to a new study. |
| Researchers examine metabolism in defective cells Posted: 11 Apr 2014 12:38 PM PDT Mitochondria produce energy for cells through oxidative metabolism, but the process produces toxic byproducts that can accumulate and cause defects in the cell's mitochondria. These defects, in turn, affect the cell's ability to generate energy and can potentially lead to cell death and are associated with aging and various neurological diseases. Researchers have examined how dietary changes at the cell level can affect cell health. |
| What happens when we try to manipulate our voice to attract a mate? Her voice is hot, his is not Posted: 11 Apr 2014 12:33 PM PDT Trying to sound sexier? Sorry, guys, it seems you just don't have what it takes. New research suggests that men cannot intentionally make their voices sound more sexy or attractive, while women have little trouble. And true to the stereotype, women will lower their pitch and increase their hoarseness to dial up the allure. |
| Tamiflu & Relenza: How effective are they? Posted: 11 Apr 2014 06:19 AM PDT Experts call on government and health policy decision makers to review guidance on use of Tamiflu in light of the most recent evidence. Tamiflu (the antiviral drug oseltamivir) shortens symptoms of influenza by half a day, but there is no good evidence to support claims that it reduces admissions to hospital or complications of influenza. |
| Confirmation of neurobiological origin of attention-deficit disorder Posted: 11 Apr 2014 06:17 AM PDT The neurobiological origin of attention-deficit disorder (ADD), a syndrome whose causes are poorly understood, has just been confirmed by a study carried out on mice. Researchers have identified a cerebral structure, the superior colliculus, where hyperstimulation causes behavior modifications similar to those of some patients who suffer from ADD. Their work also shows noradrenaline accumulation in the affected area, shedding light on this chemical mediator having a role in attention disorders. |
| New molecules working against Alzheimer's discovered Posted: 11 Apr 2014 06:17 AM PDT Eight new active molecules working against Alzheimer's have been discovered by researchers. One of the most relevant aspects of the work is that the new molecules have been designed following a mechanism which not only implies the inhibition of the deposit of the beta-amyloid protein, which causes the disease to originate and the creation of small fragments of protein, called oligomers, which originate in the initial stages of the disease and seem to play a determinant role in the development of the process. |
| How a bird flu virus spreads could prevent pandemics Posted: 10 Apr 2014 09:20 AM PDT The H5N1 bird flu virus has killed hundreds of people, despite the fact that the virus can't spread easily between people. The death toll could become much worse if the virus became airborne. A study reveals a minimal set of mutations allowing H5N1 to be transmitted through the air from one ferret to another. The findings will be invaluable for future surveillance programs and may provide warning signals of the emergence of potential pandemic strains. |
| Influenza has an Achilles' Heel: New drug reduces flu mortality Posted: 10 Apr 2014 09:19 AM PDT Flu epidemics cause up to half a million deaths worldwide each year, and emerging strains continually threaten to spread to humans and cause even deadlier pandemics. A study reveals that a drug that inhibits a molecule called prostaglandin E2 (PGE2) increases survival rates in mice infected with a lethal dose of the H1N1 flu virus. The findings pave the way for an urgently needed therapy that is highly effective against the flu virus and potentially other viral infections. |
| Decades-old mystery solved of how cells keep from bursting Posted: 10 Apr 2014 09:19 AM PDT A team led by scientists has identified a long-sought protein that facilitates one of the most basic functions of cells: regulating their volume to keep from swelling excessively. The identification of the protein, dubbed SWELL1, solves a decades-long mystery of cell biology and points to further discoveries about its roles in health and disease -- including a serious immune deficiency that appears to result from its improper function. |
