Planar Cell Polarity Genes Guide Gut Neurons
Date: Mar-12-2013The enteric nervous system (ENS), the "little brain" that resides within the gut wall, governs motility, secretion, and blood flow in the human gastrointestinal tract. Failure of the ENS to develop normally leads to congenital megacolon (Hirschsprung Disease) while loss of normal gut innervation is thought to contribute to debilitating motility disorders, such as irritable bowel syndrome. In order to prevent and treat these conditions, it is necessary to understand the molecular mechanisms that control the formation and function of the ENS...
Thousands Of Dead Pigs Found In Huangpu River, China
Date: Mar-11-2013Nearly 3,000 dead pigs have been found floating in the Huangpu River, one of Shanghai's main sources of water, according to local media reports today. Concerns about environmental pollution and water and food safety have led to a public outcry. The Shanghainese are particularly concerned about pollution because urban industrialization has brought with it serious environmental problems. According to Chinese media reports, the animals were most likely dumped in the Huangpu river in Zheijiang province...
More Than 60 Percent Of Ovarian Cancer Patients Do Not Receive Recommended Treatment, Study Shows
Date: Mar-11-2013Women Live Longer With Guideline-Based Care Women are 30 percent less likely to die of ovarian cancer if they have guideline-recommended treatment, yet nearly two-thirds of those with the disease do not receive it, often because they are cared for at hospitals that treat a small number of ovarian cancer patients. These are the findings of a study of more than 13,000 patients being presented at the Society of Gynecologic Oncology (SGO) Annual Meeting on Women's Cancer in Los Angeles, March 9-12...
Antimicrobial Resistance Poses Grave Threat
Date: Mar-11-2013The topic of antimicrobial resistance needs to be addressed - in 20 years it could result in death following minor surgery - according to the annual report by the Chief Medical Officer in the England. The warning comes as a part of the report giving an extensive overview of the antimicrobial resistance threat and infectious diseases. The report calls for politicians to treat this danger as seriously as MRSA and it emphasizes that few antibiotics have been developed in the last two decades. Over the past 30 years, each year a new infectious disease has been found...
Giant Mosquitoes Likely To Infest Florida This Summer
Date: Mar-11-2013Giant mosquitoes, the size of quarters, are likely to infest Florida this summer, according to experts from the University of Florida. These huge, biting insects, which are called Psorophora ciliata, or more commonly known as gallinippers, invaded the state last year and, according to entomologist Phil Kaufman, there may be another invasion on the way. "I wouldn't be surprised, given the numbers we saw last year," said Kaufman, an associate professor with UF's Institute of Food and Agricultural Sciences. "When we hit the rainy cycle we may see that again...
Heart Disease Among Ancient Mummies Common
Date: Mar-11-2013A new study recently published in The Lancet reveals that atherosclerosis - hardening of the arteries - was a lot more common among mummies and ancient peoples than previously thought. A total of 137 mummies from ancient Egypt, Peru, southwest America, and the Aleutian Islands in Alaska - some up to 4000 years old - were analyzed by the researchers...
Magnet Ingestion By Young Children Serious And Growing Problem
Date: Mar-11-2013Awareness needed to prevent potentially life-threatening eventPhysicians and parents must be aware of the growing danger of magnet ingestion by children because magnets can adhere to each other and cause life-threatening problems such as bowel perforations, a new case study illustrates in CMAJ (Canadian Medical Association Journal). "Modern magnet technology has transformed what was once an esoteric subtype of foreign-body ingestion into a common and lethal threat," writes Dr. Daniel Rosenfield, Department of Paediatrics, The Hospital for Sick Children (SickKids), with coauthors...
Physicians Should Not Be Responsible For Prescribing Marijuana: Editorial
Date: Mar-11-2013Physicians in Canada should not be responsible for prescribing marijuana unless the federal government commits to ensuring that it is a prescription drug, states an editorial in CMAJ (Canadian Medical Association Journal). Health Canada is proposing new regulations that will put the onus on doctors to provide authorization for their patients to take marijuana. "The language is soothing and suggests that marijuana is a medicine, albeit one that needs special oversight like morphine and for which users may be seen as patients in certain circumstances," writes Dr...
Melanoma Risk Lower In Women Who Take Aspirin
Date: Mar-11-2013Women who take aspirin on a regular basis have a lower risk for developing melanoma, according to the largest US study ever conducted into potential ways to prevent this most dangerous form of skin cancer. The researchers, from Stanford University School of Medicine, also found that the longer the participants took aspirin, the lower their risk. A report on the study is due to appear online this week in the journal Cancer...
Scientists Grow Teeth From Gum Cells
Date: Mar-11-2013The day a new "biotooth" can be grown in the gap left by a missing tooth as an alternative to having a false one implanted came a step closer recently when UK researchers revealed how they have developed a way to bioengineer new teeth from a person's own gum cells. However, it may be some years before what has been achieved in the lab is available to patients sitting in the dentist's chair. The researchers had to combine the human gum cells with a type of embryonic mouse cell to instruct the gum cells to make teeth...
