Their one mistake can cause irreparable damage; how Surgeons stay focused for hours

Organ-transplant surgeons have skills most of us can only dream about. One of them, concentrating for hours straight, is something we can aspire to emulate

Their one mistake can cause irreparable damage; how Surgeons stay focused for hoursOrgan-transplant surgeons have skills most of us can only dream about. One, concentrating for hours straight, is something we can aspire to. Transplanting a liver can take eight to 10 hours. Surgeons are on their feet the whole time, hunched over the operating table. They minimize breaks for the bathroom or refreshments. And they need […]

The dark side of India’s lucrative drug trials business

While India has guidelines on clinical trials, they don’t specify the length of time participants should take between trials

The dark side of India’s lucrative drug trials businessVasudeva Prakash left his job as a mechanic in Hyderabad three years ago for what he calls a more lucrative career: taking part in clinical trials on generic drugs. For two years, Prakash participated in trials of drugs being tested to treat HIV/AIDS and other diseases for contract research organizations (CROs) hired by global pharmaceutical […]

Using stem cells to heal broken bones can soon be a reality

Researchers found that the fractures were healed eight weeks after the procedure. The bone that grew into the empty space was as strong as surgical bone grafts. In cases where there are large gaps or fractures unable to heal, the method can be repeated to grow more bone

Using stem cells to heal broken bones can soon be a realityWhen a fracture will not heal, people are typically left with two options. One is bone grafting, the other is surgery. A new treatment that uses gene and stem cell therapies could promise success with a less-invasive procedure. Researchers led by a team from Cedars-Sinai Medical Center in Los Angeles, tested the therapy on laboratory […]

Parisian woman takes French state to court over Paris air pollution

When pollution hit the worst levels for a decade last December, her existing bronchial condition prompted an acute pericarditis attack. Her lawyer says air pollution is causing 48,000 French deaths per year. More cases would be brought in the coming weeks, in Lyon, Lille and elsewhere, he added

Parisian woman takes French state to court over Paris air pollutionClotilde Nonnez, a 56-year-old yoga teacher, says she has lived in the capital for 30 years and seen her health deteriorate. However, it became worse than ever when pollution in Paris hit record levels last December. Her lawyer says air pollution is causing 48,000 French deaths per year. “We are taking the state to task […]

Doctors say heart emergencies on planes need better treatment

About 1,000 people a year die from cardiac arrest in the air, according to data presented at a medical meeting in Geneva. Although cardiac arrests make up less than 1% of all in-flight medical emergencies, they can have particularly serious consequences

Doctors say heart emergencies on planes need better treatmentAirlines should carry more medical equipment for dealing with in-flight cardiac arrests, say doctors. Such events are rare but account for the majority of deaths on flights, figures reveal. A task force says electrocardiograms (ECGs) and defibrillators should be available on all aircraft. About 1,000 people a year die from cardiac arrest in the air, […]

Prolonged use of mid-air computer interfaces can cause arm and muscle fatigue, say Purdue University researchers

Technology has created mid-air interaction advancements in gaming, augmented and virtual reality applications and the use of mobile technologies, but fatigue from prolonged use of these gestures have become an issue. Researchers say arm fatigue – the so-called ‘gorilla arm syndrome’ – is known to negatively impact user experience

Prolonged use of mid-air computer interfaces can cause arm and muscle fatigue, say Purdue University researchersResearchers at Purdue University’s C Design Lab are studying arm and muscle fatigue connected to advancements in the use of hand gestures for mid-air computer interaction. Computer interaction improvements have included the expanding use of natural motions and gestures to control floating graphical user interfaces. As a result, fatigue from prolonged use of the motions […]

Tea causes cancer-related genetic changes in women, says study

Tea consumption was associated with alterations in DNA methylation across 28 genomic regions among women. In particular, the researchers found that tea intake appeared to alter the expression of DNAJC16 and TTC17, which are genes associated with estrogen metabolism and cancer

Tea causes cancer-related genetic changes in women, says studyNext to water, tea is the most widely consumed beverage on the planet, but a new study suggests that tea could have a greater effect on your health than hydration. The report found that tea may be able to change how certain genes are expressed in women, a process known as epigenetic changes. Tea appears […]

A flesh-eating bacterium kills man after swim with new tattoo

While the man’s nationality was not identified, vibriosis causes an estimated 80,000 illnesses and 100 deaths in the U.S. each year. According to the Centers for Disease Control and Prevention (CDC), patients become infected by consuming raw or undercooked seafood, or by exposing a wound to seawater

A flesh-eating bacterium kills man after swim with new tattooIn a bizarre incident, a 31-year-old man died after he reportedly ignored warnings about swimming after getting a new tattoo and contracted a flesh-eating bacteria infection in the Gulf of Mexico. The unidentified man, whose case was detailed in the British Medical Journal, had gotten a tattoo on his right calf five days prior to […]

Where runners go wrong

Statistics on such injuries vary, but somewhere between 30 percent and 75 percent of runners are hurt annually, a number that has led researchers to investigate a wide array of possible explanations, from modern running shoes to stretching, running frequency, weight, biomechanical misalignment and muscle imbalance

Where runners go wrongAs evidence has mounted that distance running is not just a natural human activity enjoyed by millions, but one that played a key role in evolution, a puzzle has emerged. Why, if humans are so well adapted to running long distances, do runners get hurt so often? A study out of Harvard Medical School and […]

Can premature babies be kept alive in a ‘plastic bag’ womb?

This system’s functions mimic environment of a natural womb. It is a sealed bag made up of polythene and contains amniotic fluid to provide the required nutrients and protection needed for growth and an interface delivering oxygen just like an umbilical cord

Can premature babies be kept alive in a ‘plastic bag’ womb?In the latest update from medical technology world, an artificial womb that resembles a plastic bag has been used to keep premature lambs alive for four weeks outside of their mothers’ wombs and researchers believe that this could one day be applied to premature babies. It is a sealed bag made up of polythene and […]
