According to the free radical theory of aging, first outlined in 1956, free radicals break cells down over time. As the body ages, it loses its ability to fight the effects of free radicals. Just as free radicals have different effects in different areas of the body, every antioxidant behaves differently due to its chemical properties. It is possible that free radicals are an early sign of cells already fighting disease, or that free radical formation is inevitable with age.

Dr Oz and I just had a friendly discussion on this topic - you might learn something if you tune in.
A new study has identified gene variations that determine life expectancy. Sixteen gene variations linked to life expectancy, of which 14 are newly discovered, have been recently identified by specialists. They also identify the leading causes of death, naming heart disease, cancer, and chronic respiratory diseases as some of the main culprits. Scientists have previously looked at our genetic makeup for clues that indicate how long each person is likely to live.
A new study investigates the chronology of near-death experiences. These so-called near-death experiences have been reported for centuries. Martial explains that the aim of their study was to investigate the frequency distribution of these features, both globally and according to the position of features in narratives, as well as the most frequently reported temporality sequences of the different near-death experience features. In the future, Martial hopes to explore the influence of expectations and cultural backgrounds on an individual's NDE experience.
A stressful childhood lined with destabilizing experiences - such as having divorced parents, being exposed to crime, or moving house frequently - leads to habits that could predict adult obesity, a new study finds. Previous research has convincingly linked adult obesity with low socioeconomic status both in childhood and later in life. Despite previous research pointing to links between childhood stress and adult obesity, this is the first time that LHT has been used to explain behaviors that lead to an unhealthful diet.
Kidney cysts are a relatively common health issue, and in many cases simple cysts will not cause any complications. In some cases, kidney cysts may be caused by existing kidney diseases, or long-term treatment by dialysis. Simple kidney cysts are different from the cysts that form due to polycystic kidney disease. Polycystic kidney disease is a genetic condition that may cause numerous cysts, enlarge the kidneys, and affect kidney function.
That doesn't sound like a man preparing for lengthy House-Senate negotiations on a comprehensive health care bill. Protesters in the Senate gallery chanting kill the bill disrupted proceedings on Tuesday just before the Senate voted, 51-50, to begin the health care debate. Wednesday's big vote was on a measure to repeal major parts of the existing health law - but without swapping in something new.
Teenagers who were overweight at 17 were at significantly increased risk for developing colon cancer later in adulthood, and those who were obese were at increased risk for rectal cancer as well, according to a new report. Obesity is a known risk factor for colon cancer, but earlier studies have reported mixed results about whether being overweight during adolescence confers a risk. The analysis, published in the journal Cancer, included just over one million males and 707,212 females.
Q It seems that many people who are not elite athletes are now hyper-focused on protein consumption. A The recommended intake for a healthy adult is 46 grams of protein a day for women and 56 grams for men. While protein malnutrition is a problem for millions of people around the globe, for the average adult in developed countries, we are eating far more protein than we actually need.
Available data supports the safety of Dynavax Technologies Corp's experimental hepatitis B vaccine when administered to adults, a panel of expert advisers to the US Food and Drug Administration said on Friday. Much of the panel discussion focused on the need for Dynavax to carefully track patient outcomes due to concerns about safety of the vaccine, which has been rejected twice before by the regulatory agency. A prior panel voted 13 to 1 that clinical trial data supports the vaccine's effectiveness, Dynavax said.
Shares of cigarette makers tumbled after the morning announcement, but the companies issued careful statements in support of the FDA's move. The FDA will encourage companies to reduce nicotine levels in tobacco products to less addictive levels, Dr Gottlieb said. E-cigarettes come in many fruit and alcohol flavorings to appeal to vapers of all ages, with names like Tutti Frutti and Cupcake. At the same time, Mr Myers criticized the delay given to e-cigarette and cigar companies for complying with previously released rules.
A sweetened beverage tax will take effect in Chicago on Wednesday after an Illinois judge threw out a lawsuit by retailers that argued the measure was vague and unlawful. Cook County, which includes Chicago and surrounding suburbs, joins a growing number of localities across the United States that have adopted measures to cut consumption of sugary drinks for health reasons, including Seattle and San Francisco.
It is a real word, with a complex history. In fact, this is not the first time it has intersected with politics in a public way. Nearly a century ago it was invoked and a man - considered by many to be one of the most influential neurologists of his time - ended up dead. His name was Vladimir Mikhailovich Bekhterev and the person he described as paranoiac was Joseph Stalin. That's when the Russian doctor shared his diagnosis with a few acquaintances.
Volunteering at least two hours a week may go a long way toward helping to ease feelings of loneliness and social isolation, a study of recent widows suggests. The recent widows who started volunteering at least two hours a week developed lower levels of loneliness on par with married people who spend similar amounts of time giving back to their communities.
With any herbicide exposure at work, people were more than twice as likely to develop COPD by middle age, and workplace pesticide exposure was associated with 74 percent higher odds of the common lung disease, researchers report in Thorax. Over a lifetime, pesticides and herbicides may pose an even bigger added risk for breathing disorders, the study also found. Each ten-year increase in occupational exposure to pesticides carried a 12 percent increased risk of COPD and a 16 percent higher risk of developing chronic bronchitis.
AbbVie Inc said on Friday it had received European approval to market its drug for treatment of all six major forms of hepatitis C The company said the approval of Maviret was supported by eight studies evaluating more than 2,300 patients in 27 countries. The drug, a combination of glecaprevir and pibrentasvir, showed 97.5 percent cure rate in the eight weeks of treatment of patients, who have never undergone treatment.
Most who responded complained that electronic records undermined their connection with patients. The study divided doctors into those who primarily see patients in hospitals and those who primarily see them in offices. Hospital-based doctors' chief complaint was that EHRs disconnected them from patients, while office-based doctors most frequently griped that computer work degraded the quality of their interactions with patients. Nowadays, doctors may be more keenly aware of their time away from patients because it's all spent sitting at a computer, he suggested.
On Thursday, Ms Yates, who works as a caregiver, said in statement that the hospital had denied us our final wish. The case also spurred questions about the wisdom of offering parents the hope of experimental treatment when faced with an incurable disease. The treatment had been tested on mice and on 18 people with a mutation in a gene known as TK2. Ms Yates chided the hospital, saying it had dragged its feet about the treatment until it was too late.
High intake of sugary foods and drinks may harm men's mental health, suggest researchers. The downfalls of high sugar consumption are not limited to poor dental health and weight gain; a new study finds that eating too much sugar may also increase men's long-term risk of mental health disorders. For this latest research, the team set out to gain a better understanding of whether sugar consumption might influence the development of mental health disorders.
The American Civil Liberties Union of New Jersey and Ms Hickox's lawyers, Norman Siegel and Steven Hyman, filed a civil rights lawsuit on her behalf in Federal District Court in Newark. Gov Chris Christie and the former state health commissioner, Mary E O'Dowd, were named in the suit. It also guarantees a person the right to privacy so long as it does not interfere with vital public health needs.
