How The Genetic Structure Of African Mosquitoes Is Evolving Has Implications For Controlling Malaria
Date: Apr-03-2013A surprising research discovery in mosquitoes could affect future prospects for malaria control. A team of scientists from West Africa, the United States and the United Kingdom found that the mosquito, Anopheles gambiae, which was thought to be splitting into two completely new species, may actually have a more complex range of forms due to frequent inter-mating. The resulting hybrids may have implications for insecticide resistance and malaria parasite infectivity...
Comparison Of 3 Water Pills For Heart Failure Finds The Most Effective May Be The Least Prescribed
Date: Apr-03-2013Loop diuretics, more commonly known as water pills, are the most widely prescribed heart failure medications, but few studies had extensively compared their effectiveness until Yale School of Medicine researchers examined three approved loop diuretics and found that even though one of them might offer more benefit, it is rarely prescribed. Published in the early edition of the Journal of the American College of Cardiology, the research compared the potential benefits of using one of three loop diuretics: toresemide, furosemide, and bumetanide...
Men More Depressed Than Women If Childless
Date: Apr-03-2013Men are just as likely as women to want kids, and they feel more depressed, isolated, angry and sad than women if they are childless, according to a new study. The research was presented at the British Sociological Association yearly conference in London on April 3rd. The researchers also discovered that some of the leading influences on a man's desire to have children are expectations from family and culture. Robin Hadley, a researcher from Keele University, Staffordshire, England, conducted a survey which involved 27 men and 81 women who were not parents...
Direct Association Between Type 2 Diabetes And Obesity Found
Date: Apr-03-2013Obesity has been historically known as a risk factor for type 2 diabetes, and now a key mechanism has been found in the immune system that plays a part in the development of obesity-linked type 2 diabetes. The outcome was found in a study led by researchers from King's College London, UK and was published in the journal Cell Metabolism. The findings are a stepping stone for new treatment methods and prevention of this health issue that has become extremely prevalent worldwide...
Tonsillectomy Helps Adults Too
Date: Apr-03-2013Adults who undergo a tonsillectomy have fewer symptoms of pharyngitis, visit their doctors with throat problems less often, and miss work less, researchers from the University of Oulu and Oulu University Hospital, both in Finland, reported in CMAJ (Canadian Medical Association Journal). The researchers wrote that tonsillectomy may help some adults with recurrent or chronic pharyngitis. There are very few studies on the benefits and potential harms regarding adult patients undergoing tonsillectomy, the authors explained...
Duloxetine Reduces Chemo-Induced Neuropathy
Date: Apr-03-2013Duloxetine, an antidepressant, was shown to reduce painful peripheral neuropathy caused by neurotoxic chemotherapy in a study published in JAMA. Researchers from the University of Michigan School of Nursing added that duloxetine benefited the majority of patients in their study. Many patients who undergo chemotherapy develop neuropathy - an unpleasant sensation of tingling and numbness in their hands and feet. This discomfort can sometimes work its way up to the shins, calf muscles, and the forearm. In about 2 to 4 in every 10 patients who undergo neurotoxic chemotherapy (e.g...
Researchers Discover How Cells Distinguish Friend From Foe
Date: Apr-03-2013Researchers at UC Davis have shown how the innate immune system distinguishes between dangerous pathogens and friendly microbes. Like burglars entering a house, hostile bacteria give themselves away by breaking into cells. However, sensing proteins instantly detect the invasion, triggering an alarm that mobilizes the innate immune response. This new understanding of immunity could ultimately help researchers find new targets to treat inflammatory disorders. The paper was published in Nature...
Bowel Cancer Rates Increase In The UK
Date: Apr-03-2013Over the last three and a half decades, the rate of bowel cancer among British men has increased by 30 percent while there's only been a 6 percent increase in women, according to Cancer Research UK. The new data come from the awareness and fundraising campaign carried out by The Bobby Moore Fund. In 1975, forty-five out of every 100,000 British men suffered from bowel cancer, this rate increased to 58 per 100,000 men in 2008-10. The rise translates into an overall increase of 29 percent in the prevalence of bowel cancer...
New Test Kit Enables Effective Treatment For Newly Identified Deadly Lymphoma
Date: Apr-03-2013An international research team has identified a new type of deadly intestinal lymphoma that is particularly common in Asia. The team, led by clinician-scientists from the SingHealth Academic Healthcare Cluster, also developed a new diagnostic test to accurately identify these patients. The study, carried out by the Singapore Lymphoma Study Group at Singapore General Hospital (SGH) and the National Cancer Centre Singapore (NCCS), has an immediate impact on patient care, with doctors now able to diagnose patients accurately and tailor more effective treatment strategies to improve outcomes...
Studying The Epigenetics Of Hormone Therapy Resistance Leads To New Drug Target
Date: Apr-03-2013A team of international cancer researchers led by Dr. Mathieu Lupien at the Princess Margaret Cancer Centre, University Health Network, has identified the signalling pathway that is over-activated in estrogen receptor (ER)-positive breast cancer cells that are resistant to hormone therapies such as tamoxifen, aromatase inhibitors or fulvestrant. Resistance to hormone therapy is reported in almost half of ER-positive breast cancer patients and no cure is currently available. The fact that the pathway, called Notch, is a drug target creates hope for a new therapy...
