A revolutionary surgical procedure could repair severed nerves within minutes and set the patient firmly on the road to recovery within mere days or weeks, reveals a study. The study, led by researcher George Bittner, professor at University of Texas, used a cellular mechanism similar to that of many invertebrates to repair damage to axons, an extension of the nerve [...]
Heart failure could also be linked to thinning of bones (osteoporosis), an offshoot of old age. “Our study demonstrates for the first time that heart failure and thinning of bones go hand in hand,” said Sumit Majumdar, University of Alberta in Edmonton, Canada, who led the study. “Understanding the mechanism between heart failure and osteoporosis might lead to new treatments [...]
Austrian scientists have found vitamin D’s deficiency, long held as a risk factor for diseases like diabetes, may cause infertility among men and women. This deficiency has also been a risk factor for diseases like osteoporosis, or the thinning of bone tissue and loss of bone density over time. After analysing numerous studies, the Austrian physicians Barbara Obermayer-Pietsch and Elisabeth [...]
Doctors and nurses will be trained in burn care and management as the country reports nearly seven million burn injuries in infernos like the one in Kolkata’s AMRI hospital in December 2011, experts from the National Academy of Burns-India (NABI) said here Thursday. “In a three-day conference starting Feb 3, the NABI and experts from NDMA (National Disaster Management Authority) [...]
A head patch worn on the brow has been found promising in non-invasively monitoring blood oxygen among stroke patients. This device, known as frontal near-infrared spectroscopy (NIRS), could offer hospital physicians a safe and low-cost way to monitor strokes in real time, suggests a study. A stroke is a sudden interruption in the blood supply to the brain. Most strokes [...]
Night-time urination can be a problem for those having an enlarged prostate, but it can affect youngsters, too, reveals a study. Danish researchers have found that sleep deprivation causes healthy children, aged between eight and 12 years, to urinate more frequently, excrete more sodium in their urine, have altered regulation of the hormones important for excretion, and have higher blood [...]
People who died after a stroke had severe memory loss in the years before stroke, compared to people who survived the stroke or people who didn’t have a stroke, says a new study. “People who die after stroke may have worse underlying disease prior to stroke, said M. Maria Glymour, senior study author and assistant professor at the Harvard School [...]
A flesh-eating form of pneumonia that is easily passed between healthy people on public transport is spreading across Britain, the Daily Mail reported. The deadly strain of MRSA called USA300 passes easily through skin-to-skin contact. It can survive on surfaces and so has the potential to be picked up on buses and tubes. It was first seen in the US [...]
Tuberculosis patients may receive treatments in the future according to what version they have of a single ‘Goldilocks’ gene, says an international research team from Oxford University, King’s College London, Vietnam and the USA. This is one of the first examples in infectious disease of where an individual’s genetic profile can determine which drug will work best for them – [...]
Unravelling a facet of the heart’s mysterious workings, scientists have stumbled upon electrical property in arteries not seen before in mammalian tissues. Scientists found that the wall of the aorta, the largest blood vessel carrying blood from the heart, exhibits ferroelectricity, a response to an electric field known to exist in inorganic and synthetic materials. A ferroelectric material is an [...]
Do white and red wine, the latter touted for its many health benefits, really stave off heart disease? The jury is still out on that one. “It’s complicated,” says Juergen Rehm, director of social and epidemiological research at Centre for Addiction and Mental Health (CAMH), who conducted the meta-analysis into the link between alcohol consumption and heart disease. “While a [...]
School children whose mothers nurtured them lovingly have a larger hippocampus, a key brain area vital for learning, memory and response to stress. Research by the Washington University School of Medicine, St. Louis, is the first to show that changes in this critical region of children’s brain anatomy are linked to a mother’s nurturing. “This study validates something that seems [...]
Production of sperm not only seems to lower one’s immunity but is also a more biologically taxing process than previously thought. Damian Dowling of Monash University’s School of Biological Sciences and Leigh Simmons, professor at the University of Western Australia, have investigated the trade-off between sperm quality and immunity. “Males that invested heavily in their sperm paid the price of [...]
Zapping a male’s private parts with ultrasound could be one of the most effective and non-invasive forms of contraception. Experiments conducted by James Tsuruta, from the University of North Carolina, US, have shown they lowered sperm counts in mice, potentially opening the way to reversing fertility in men. Tsuruta, who led the study, said: “Our non-invasive ultrasound treatment reduced sperm [...]
Information technology (IT) can make healthcare accessible and affordable to more people in the country, industry lobby the National Association of Software and Services Companies (Nasscom) said here Monday. “IT can provide access to healthcare facilities. Also, it can have a positive impact on affordability and effectiveness of healthcare in India,” Som Mittal, president of the IT-BPO sector apex body, [...]
Battling for life at the All India Institute of Medical Sciences (AIIMS), two-year-old battered and abandoned baby Falak underwent brain surgery to remove fluids even as she developed respiratory problems, a doctor said. The baby has been put on ventilator. “We have done a small brain surgery to remove fluids from her brain. We suspect that there could be infection [...]
Silk is set to make a leap from dressing Indian brides to potentially growing replacement tissue for damaged hearts, keeping them healthy and evergreen. Max Planck scientists in Germany have succeeded in loading cardiac muscle cells onto a 3D scaffold (framework), created using the Tasar silk produced by a tropical silkworm. Of all the body’s organs, the human heart is [...]
What you think about your illness matters just as much, if not more, than the factors and conditions that determine your health condition. Keith Petrie of the University of Auckland and John Weinman of the Institute of Psychiatry at King’s College, London, conducted a review of the existing literature on patients’ perceptions of illness. “A doctor can make accurate diagnoses [...]
Bihar, which has not reported a single case of polio since September 2010, is now turning its attention to kala azar, a disease transmitted by the sand fly that killed at least 50 people and affected 15,000 in the state last year. “Bihar has not reported even a single case of polio in the last 16 months and the state [...]
The HIV drug Viread will now be available in powder form for HIV positive children after its approval by the US Food and Drug Administration (FDA), a bio-pharmaceutical company said Sunday. The move is expected to benefit millions of HIV positive children. “There remains an unmet need for heat-stable, taste-neutral pediatric formulations that do not require cold storage, particularly in [...]
