Doctors remove nail clipper from toddler's stomach in China
Children tend to be curious about everything but leaving certain objects within their reach can be hazardous. In an alarming incident from China, a child was rushed to a hospital when he swallowed a nail clipper. The toddler's mother was using the clipper when he grabbed it and started running around. When she tried to chase him, he saw it as a game and put the clipper in his mouth as he swallowed it.
Meditation may lower anxiety, boost heart health
Just a single session of meditation can alleviate anxiety and boost heart health, a study has found. Additionally, shortly after meditating, and even one week later, the group reported anxiety levels were lower than pre-meditation levels. It sounds like a late-night commercial: In just one hour you can reduce your anxiety levels and some heart health risk factors. Even a single hour of meditation appears to reduce anxiety and some of the markers for cardiovascular risk, said John Durocher, assistant professor at Michigan Technological University.
Heart patients who walk faster hospitalised less
The researchers recorded the number of all-cause hospitalisations and length of stay of the participants over the next three years. Increasing the pace of walking may bring some added benefits as researchers have found that faster-walking patients with heart disease are hospitalised less. The study was conducted in 1,078 hypertensive patients, of whom 85 per cent also had coronary heart disease and 15 per cent also had valve disease. A total of 359 patients were identified as slow walkers, 362 intermediate and 357 fast walkers.
Medication use increases in newly-diagnosed dementia patients
Researchers have found an increase in medication use by the patients who have been newly-diagnosed with dementia and they may consume unnecessary or inappropriate medicines that increase the risk of side effects. According to the researchers, potentially inappropriate or unnecessary medications included sleeping tablets, pain drugs, depression drugs and acid reflux drugs. These medications are typically recommended for short term use but are commonly used long term by people with dementia, Gnjidic said.
Scientists unveil how cancer-causing virus anchors itself to human DNA
Scientists have unveiled how a cancer-causing virus anchors itself to our DNA, paving the way for doctors to treat incurable diseases by flushing out viruses that permanently embed themselves in human cells. The researchers used a microscope built by them to unveil the structure of the tether used by a virus called Kaposi's sarcoma-associated herpesvirus (KSHV). Until now, such tethers have largely eluded scientists because they are so diabolically small, defying even the most high-tech approaches to determining their form.
People perform better when they are being watched: Study
The findings, published in the journal Social Cognitive and Affective Neuroscience, could help people become more effective in the workplace and in school. An audience can serve as an extra bit of incentive, said Vikram Chib, an assistant professor at Johns Hopkins University in the US. Together these signals triggered activity in the ventral striatum, an area of the brain that motivates action and motor skills. Only two participants didn't perform better in front of others.
Study reveals dementia patients take unnecessary medicines
Such as sleeping pills, painkillers, depression drugs and antacids - increases in patients newly diagnosed with dementia, a study has found. For the study published in the Journals of Gerontology: Medical Sciences, researchers from Yale University and University of Kentucky in the US studied nearly 2,500 people. Potentially inappropriate or unnecessary medications included sleeping tablets, pain drugs, depression drugs and acid reflux drugs. These medications are typically recommended for short term use but are commonly used long term by people with dementia, Gnjidic said.
'Biomedical tattoo' might catch cancer early
Often, cancer goes undetected until its advanced stages, when treating it becomes very difficult and the outlook less promising. Researchers from Switzerland are developing an implant that could alert wearers to the presence of cancer early on. A biomedical tattoo that looks like a brown mole when it 'lights up' could alert its 'wearer' to early signs of cancer.
Parkinson's: Targeting new compound slows disease in rats
New research finds that acrolein, a byproduct of oxidative stress, is key in the progression of Parkinson's disease. Targeting the compound was found to slow down the condition in rats - a discovery that may soon lead to new drugs for the illness. Parkinson's disease affects approximately 500,000 people in the United States, with 50,000 new cases being diagnosed every single year. The researchers found that the compound called acrolein tends to build up in the brain tissue of rats affected by Parkinson's.
How muscular strength improves brain health
Turns out, muscular strength, measured by handgrip, is an indication of how healthy our brains are. Using data from the 475,397 participants from all around the UK, a research showed that on average, stronger people performed better across every test of brain functioning used. Tests included reaction speed, logical problem solving, and multiple different tests of memory.
Easier detection of concussions!
Turns out, easier detection of concussions is possible. Six specific small molecules from blood plasma were discovered in a group of college athletes who had been diagnosed with concussions. When these molecules were assessed, their combined presence accurately predicted whether teammates had sustained an mTBI or not. Researchers at UCI are helping advance technologies and therapeutic approaches that may benefit all societies, but are directly relevant to their local populations.
Running marathon boosts immunity
Debunking the 'myth' that strenuous exercise increases infection risk by suppressing the immune system, a new study says that competing in endurance sports like marathon running may actually be beneficial for upping immunity. Research from the 1980s, which focused on events such as the Los Angeles Marathon, asked competitors if they had symptoms of infections in the days and weeks after their race. Many did, leading to a widespread belief that endurance sports increase infection risk by suppressing our immune system.
New study finds organic cotton tampons no safer against toxic shock
Organic cotton tampons are often advertised as safer alternatives, but a study Friday said they are not better than regular tampons at preventing toxic shock syndrome. Women have long been advised to change tampons regularly to avoid the risk of toxic shock syndrome, a rare but life-threatening condition that arises from a bacterial infection. In recent years, a number of new female hygiene products have hit the market, including tampons made from organic cotton and menstrual cups that can be rinsed between uses.
Mother's premature menopause affects daughter's fertility: Study
Mother's premature menopause can affect her daughter's fertility and is known as hereditary infertility. Dr Anubha Singh, Gynecologist and IVF Expert explained this and said A mother's menopausal age holds vital clues to the daughter's fertility. Mothers who experience early menopause have daughters with compromised levels of the hormones needed for ovulation and egg reserve indication. Menopause seems accelerated in women whose mothers experienced early menopause or premature ovarian failure added Dr Anubha Singh.
For heavy lifting, use exoskeletons with caution: The wearable robotics don't eliminate stress -- they just shift it to other parts of the body -
Someone is tugging and pulling on you in directions you're not expecting, and your body has to compensate for that. They found that wearing the exoskeleton increased compressive spinal loads up to nearly 53 percent compared to not wearing it. Stress on different muscles in the torso increased anywhere from 56 percent to 120 percent while wearing it. Passive exoskeletons, like the one tested in this study, contain braces and springs to help support areas of the body.
Immune diversity among the KhoeSan population
A new study of the KhoeSan of Southern Africa has improved the understanding of immune diversity among the oldest surviving indigenous population in the world. By analyzing genes of two distinct groups of the KhoeSan, investigators were able to find a level of diversity and divergence in immune cell repertoires much higher than identified in any other population.
Insecticide resistance in a major malaria vector
Researchers from LSTM, with partners from a number of international institutions, have shown the rapid selection of a novel P450 enzyme leading to insecticide resistance in a major malaria vector. Resistance involves a cytochrome P450 enzyme CYP9K1 which for the first time a role in pyrethroid resistance is established. After target site-based (kdr) pyrethroid resistance was detected in 2004 and rose in frequency the carbamate bendiocarb was introduced for IRS.
Genomics study in Africa: Demographic history and deleterious mutations
The accumulation of disease-causing genetic variants, known as the burden of deleterious mutations, varies from one population to another depending on its past. This enabled us to measure the rise and fall in the burden of deleterious mutations as the population size contracted and expanded, explains the scientist. What prevented the hunter-gatherers suffering from an excess of deleterious mutations was both their high ancestral genetic diversity and a strong and constant admixture with farmers.
Students learn Italian playing Assassin's Creed video game
D, associate professor of languages, literatures and cultures at SLU, started playing video games in 1975 when he was 12. By the mid-1980s, he was playing textual adventures, and soon realized his English was improving rapidly as he played. In my Italian Renaissance literature course, for example, students explore Florence as it flourished under the Medici by playing Assassin's Creed II, Bregni says in the paper. Bregni uses games to reinforce vocabulary and grammar, introduce cultural data and teach students to problem solve in Italian.
Bariatric surgery provides hope for morbid obese kid sisters
Almost three years after they first came into limelight, two sisters from Una may have hopefully found a solution to their morbid obesity, a result of a genetic condition. The sisters Yogita and Amisha Nandwana both aged 8.5 years and 6 years respectively lost close to 10 kgs each following a sleeve gastrectomy bariatric surgery. The surgery involves reducing the size of the stomach pouch as a result of which the ability to consume food goes down.
