Frequent Brain Concussion Can Lead To Suicide.
When historic National Football League celebrated linebacker Junior Seau killed himself last year, he had a catastrophic wisdom disorder probably brought on by repeated hits to the head, the US National Institutes of Health has concluded. The NIH scientists who intentional Seau's brain unflinching that he had chronic traumatic encephalopathy (CTE). They told the Associated Press on Thursday that the cellular changes they apothegm were similar to those found in autopsies of people "with exposure to repetitive head injuries".
The brawl - characterized by impulsivity, depression and erratic behavior - is only diagnosed after death. Seau, 43, who played pro football for 20 seasons before his retirement in 2009, jigger himself in the box last May 2012. His family donated his brain for research.
Some experts feel - but can't prove - that CTE led to Seau's suicide. "Chronic wounding encephalopathy is the thing we have typically seen in a lot of the athletes," said Dr Howard Derman, manager at the Methodist Concussion Center in Houston. "Rather than say 'this caused this,' I expect the observation is that there have been multiple pro football players now who have committed suicide: Dave Duerson, Andre Waters, John Grimsley - although Grimsley was just reported as a gun accident".
Some fight that these players became depressed once they were out of the limelight or because of marital or monetary difficulties, but Derman thinks the evidence goes beyond that."Yes, all that may be universal on - but it still remains that the majority of these players who have committed suicide do have changes of chronic injurious encephalopathy. We feel that that is also playing a role in their mental state".
But, Derman cautioned, "I can't verbalize that chronic traumatic encephalopathy causes players to commit suicide". Chronic shocking encephalopathy was first noticed in boxers who suffered blows to the head over many years. In late years, concerns about CTE have led high school and college programs to regulate hits to the head, and the National Football League prohibits helmet-to-helmet hits.

Sharing Photos Online Is A Way Of Dating
Sharing Photos Online Is A Way Of Dating.
A original observe finds that the practice of "sexting" - sending salacious texts or naked photos over the Internet - is now a key tool for Americans bent on infidelity. Sexting, which notoriously back former Democratic Congressman Anthony Weiner his job, is "alive and well," said sociologist Diane Kholos Wysocki, the study's result in author. In fact it's a neck of the woods of the whole extra-marital mating ritual, according to Wysocki, who said adulterous interactions that begin online seem to follow a scheduled pattern.
And "People meet, then they send pictures, then they send naked pictures, then they proceed and at meet if they find that they're compatible". The study, based on a survey of almost 5,200 users of a website loyal to extra-marital dating called ashleymadison.com, doesn't say anything about the habits of the American folk in general.
And, as Kholos Wysocki acknowledged, its value is also limited because it only includes those relatives who volunteered to take part and were already using the site. "Any time you get a group of people on the Internet, we can't stipulate it's representative," said Kholos Wysocki, a professor of sociology, University of Nebraska at Kearney. However, she said the appraisal does offer insight into why people choose to hamper married but still have affairs.
As of a year ago, the "ashleymadison dot com" site, whose motto is "Life is short. Have an affair," claimed more than 6 million members. Working with the site, Kholos Wysocki in 2009 posted a examination for members with 68 questions.
The results appear in a current online outflow of the journal Sexuality & Culture. Those who responded tend to be upscale (with a median proceeds of about $86000), mostly married (64 percent) and highly educated (about 70 percent attended college, and 20 percent had advanced degrees). More than 6 out of every 10 respondents were male.

New Way To Fight Mosquitoes
New Way To Fight Mosquitoes.
Researchers have scholastic more about how mosquitoes spot skin odor, and they say their findings could lead to better repellants and traps. Mosquitoes are attracted to our coat odor and to the carbon dioxide we exhale. Previous research found that mosquitoes have special neurons that sanction them to detect carbon dioxide. Until now, however, scientists had not pinpointed the neurons that mosquitoes use to catch skin odor.
The new study found that the neurons used to detect carbon dioxide are also worn to identify skin odor. This means it should be easier to find ways to block mosquitoes' faculty to zero in on people, according to the study's authors. The findings appeared in the Dec 5, 2013 culmination of the journal Cell.

Doctors Are Using A New Method Of Treatment Of Peyronie's Disease
Doctors Are Using A New Method Of Treatment Of Peyronie's Disease.
The at the outset upper treatment for unusual curvature of the penis has been approved by the US Food and Drug Administration, the instrumentality announced Friday Dec 2013. Men with the condition, called Peyronie's disease, have a wad in the penis that causes curvature of at least 30 degrees during an erection. The disorder, which is caused by scratch tissue under the skin of the penis, can cause bothersome symptoms during sex.
Until now, surgery was the only medical way out for men with the condition, according to an FDA scandal release. The FDA's approval of the drug Xiaflex (collagenase clostridium histolyticum) to daily men with Peyronie's disease calls for a maximum of four treatment cycles. Each recycle consists of two injections and one penile remodeling procedure performed by a health care professional. The endorsement is based on two studies involving more than 800 men with Peyronie's disease.

Alcohol Affects The Child Before Birth
Alcohol Affects The Child Before Birth.
Children who are exposed to fire-water before they are born are more odds-on to have problems with their social skills, according to new research in Dec, 2013. Having a or formal who drank during pregnancy was also linked to significant emotional and behavioral issues, the study found. However, these kids weren't certainly less intelligent than others. The researchers, Justin Quattlebaum and Mary O'Connor of the University of California, Los Angeles, demand their findings point to an urgent insufficiency for the early detection and treatment of social problems in kids resulting from exposure to alcohol in the womb.
Early intervention could enhance the benefits since children's developing brains have the most "plasticity" - ability to swop and adapt - as they learn, the study authors pointed out. The study, published online and in a new print edition of Child Neuropsychology, involved 125 children between 6 and 12 years old. Of these kids, 97 met the criteria for a fetal liquor spectrum disorder.

Patients With Alzheimer's Disease Observed Blunting Of Emotional Expression
Patients With Alzheimer's Disease Observed Blunting Of Emotional Expression.
Patients with Alzheimer's virus often can seem shrinking and apathetic, symptoms frequently attributed to memory problems or tribulation finding the right words. But patients with the progressive brain disorder may also have a reduced knack to experience emotions, a new study suggests. When researchers from the University of Florida and other institutions showed a undersized group of Alzheimer's patients 10 positive and 10 negative pictures, and asked them to berate them as pleasant or unpleasant, they reacted with less intensity than did the group of healthy participants.
And "For the most part, they seemed to empathize the emotion normally evoked from the picture they were looking at ," said Dr Kenneth Heilman, superior author of the study and a professor of neurology at the University of Florida's McKnight Brain Institute. But their reactions were unalike from those of the healthy participants. "Even when they comprehended the scene, their irrational reaction was very blunted". The study is published online in the Journal of Neuropsychiatry and Clinical Neurosciences.
The examine participants - seven with Alzheimer's and eight without - made a attend on a piece of paper that had a happy face on one end and a sad one on the other, putting the mark closer to the in seventh heaven face the more pleasing they found the picture and closer to the sad face the more distressing. Compared to the robust participants, those with Alzheimer's found the pictures less intense.
They didn't find the pleasant pictures (such as babies and puppies) as gregarious as did the healthy participants. They found the negative pictures (snakes, spiders) less negative. "If you have a blunted emotion, hoi polloi will say you look withdrawn". One important take-home bulletin is for families and physicians not to automatically think a patient with blunted emotions is depressed and appeal for or prescribe antidepressants without a thorough evaluation first.

New Promise Against Certain Types Of Lung Cancer
New Promise Against Certain Types Of Lung Cancer.
An tentative cancer painkiller is proving effective in treating the lung cancers of some patients whose tumors communicate a certain genetic mutation, new studies show. Because the mutation can be produce in other forms of cancer - including a rare form of sarcoma (cancer of the soft tissue), youth neuroblastoma (brain tumor), as well as some lymphomas, breast and colon cancers - researchers assert they are hopeful the drug, crizotinib, will prove effective in treating those cancers as well. In one study, researchers identified 82 patients from in the midst 1500 patients with non-small-cell lung cancer, the most base type of lung malignancy, whose tumors had a mutation in the anaplastic lymphoma kinase (ALK) gene.
Crizotinib targets the ALK "driver kinase," or protein, blocking its occupation and preventing the tumor from growing, explained retreat co-author Dr Geoffrey Shapiro, director of the Early Drug Development Center and affiliated professor of medicine at Dana-Farber Cancer Institute and Harvard Medical School, Boston. "The cancer cubicle is actually addicted to the activity of the protein for its flowering and survival. It's totally dependent on it. The idea is that blocking that protein can put an end to the cancer cell".
In 46 patients taking crizotinib, the tumor shrunk by more than 30 percent during an usual of six months of taking the drug. In 27 patients, crizotinib halted lump of the tumor, while in one patient the tumor disappeared.
The drug also had few side effects. The most common was compassionate gastrointestinal symptoms. "These are very positive results in lung cancer patients who had received other treatments that didn't do or worked only briefly. The bottom line is that there was a 72 percent chance the tumor would contract or remain stable for at least six months".
The study is published in the Oct 28, 2010 version of the New England Journal of Medicine. In recent years, researchers have started to suppose of lung cancer less as a single disease and more as a group of diseases that rely on specified genetic mutations called "driver kinases," or proteins that enable the tumor cells to proliferate.
That has led some researchers to concentration on developing drugs that target those specific abnormalities. "Being able to repress those kinases and disrupt their signaling is evolving into a very successful approach".

The Use Of Red Meat Can Lead To Atherosclerosis
The Use Of Red Meat Can Lead To Atherosclerosis.
A parasynthesis found in red vital part and added as a supplement to popular energy drinks promotes hardening and clogging of the arteries, otherwise known as atherosclerosis, a fresh study suggests April 2013. Researchers conjecture that bacteria in the digestive tract convert the compound, called carnitine, into trimethylamine-N-oxide (TMAO). Previous investigating by the same team of Cleveland Clinic investigators found that TMAO promotes atherosclerosis in people. And there was an another twist: The workroom also found that a diet high in carnitine encourages the flowering of the bacteria that metabolize the compound, leading to even higher TMAO production.
The type of bacteria living in our digestive tracts are dictated by our long-term dietary patterns. A council high in carnitine absolutely shifts our gut microbe composition to those that like carnitine, making meat eaters even more reachable to forming TMAO and its artery-clogging effects," study leader Dr Stanley Hazen, chairwoman of preventive cardiology and rehabilitation in Cleveland Clinic's Heart and Vascular Institute, said in a clinic dirt release. Hazen's team looked at nearly 2600 patients undergoing sincerity evaluations.
The researchers found that consistently high carnitine levels were associated with a raised risk of soul disease, heart attack, stroke and heart-related death. They also found that TMAO levels were much deign among vegetarians and vegans than among people with unrestricted diets (omnivores). Vegetarians do not consume meat while vegans do not eat any animal products, including eggs and dairy.

Scientists Recommend Physical Training Schedule
Scientists Recommend Physical Training Schedule.
Older women are physically tranquil for about two-thirds of their waking hours, according to rejuvenated research. But that doesn't mean they're just sitting still. Although women in the mug up appeared to be inactive for a good portion of the day, they a lot moved about in short bursts of activity, an average of nine times an hour. "This is the key part of an ongoing study, and the first paper to look at the patterns of activity and sedentary behaviors," said command author Eric Shiroma, a researcher at Brigham and Women's Hospital, in Boston.
And "Some on says that sitting for long periods is harmful and the recommendation is that we should get up every 30 minutes, but there's brief hard data available on how much we're sitting and how often we get up and how measures such as these affect our trim risks". Results of the study are published as a letter in the Dec 18, 2013 issue of the Journal of the American Medical Association.
Previous studies have suggested that the more kinfolk sit each day, the greater their hazard for chronic health problems, such as heart disease, diabetes and cancer. The current bookwork included more than 7000 women whose average age was 71 years. For almost seven days, the women wore devices called accelerometers that reach movement. However, the device can't certain if someone is standing or sitting, only if they're still or moving.
The women wore the devices during their waking hours, which averaged concentrated to 15 hours a day.A break in sedentary (inactive) behavior had to cover at least one minute of movement, according to the study. On average, the women were physically still for 65,5 percent of their day, or about 9,7 hours. The average number of sedentary periods during the age was 86, according to the study.

Physical Activity And Adequate Levels Of Vitamin D Reduces The Risk Of Dementia
Physical Activity And Adequate Levels Of Vitamin D Reduces The Risk Of Dementia.
Physical pursuit and acceptable levels of vitamin D appear to abridge the risk of cognitive decline and dementia, according to two large, long-term studies scheduled to be presented Sunday at the International Conference on Alzheimer's Disease in Hawaii. In one study, researchers analyzed matter from more than 1200 mortals in their 70s enrolled in the Framingham Study. The study, which has followed populate in the town of Framingham, Mass, since 1948, tracked the participants for cardiovascular health and is now also tracking their cognitive health.
The manifest activity levels of the 1200 participants were assessed in 1986-1987. Over two decades of follow-up, 242 of the participants developed dementia, including 193 cases of Alzheimer's. Those who did referee to awful amounts of exercise had about a 40 percent reduced peril of developing any type of dementia. People with the lowest levels of physical activity were 45 percent more acceptable to develop any type of dementia than those who did the most exercise.
These trends were strongest in men. "This is the in the first place study to follow a large group of individuals for this long a period of time. It suggests that lowering the danger for dementia may be one additional benefit of maintaining at least moderate physical activity, even into the eighth decade of life," learn author Dr Zaldy Tan, of Brigham and Women's Hospital, VA Boston and Harvard Medical School, said in an Alzheimer's Association front-page news release.
The assign study found a link between vitamin D deficiency and increased risk of cognitive harm and dementia later in life. Researchers in the United Kingdom analyzed data from 3325 folk aged 65 and older who took part in the third US National Health and Nutrition Examination Survey.
The participants' vitamin D levels were reasoned from blood samples and compared with their demeanour on a measure of cognitive function that included tests of memory, orientation in time and space, and know-how to maintain attention. Those who scored in the lowest 10 percent were classified as being cognitively impaired.
