Polycystic ovarian syndrome is very common, affecting about six to seven per cent of women in Britain. Women who have the condition may have raised testosterone levels and irregular periods. Often ovulation does not take place every cycle, so it is sometimes more difficult to get pregnant. The symptoms of PCOS can improve if you stay slim and exercise regularly. Stopping smoking may also boost your fertility. However, at 39, lifestyle measures alone are sometimes not enough to maximise your chances of conceiving. If you are not ovulating regularly, there are medications available to induce ovulation and thereby improve your chances of getting pregnant. Even women without PCOS are advised to have further investigations if they are over the age of 35 and are having trouble conceiving. It is certainly worth seeing your GP to discuss this in more detail, so that you are aware of all your options.

Oxidative stress has been linked to aging, cancer and other diseases in humans. Paradoxically, researchers have suggested that small exposure to oxidative conditions may actually offer protection from acute doses. Now, scientists at the University of California, San Diego, have discovered the gene responsible for this effect. Their study, published in PLoS Genetics on May 29, explains the underlying mechanism of the process that prevents cellular damage by reactive oxygen species (ROS).

“We may drink pomegranate juice to protect our bodies from so-called ‘free radicals’ or look at restricting calorie intake to extend our lifespan,” said Trey Ideker, PhD, chief of the Division of Genetics in the Department of Medicine at UC San Diego’s School of Medicine and professor of bioengineering at the Jacobs School of Engineering. “But our study suggests why humans may actually be able to prolong the aging process by regularly exposing our bodies to minimal amounts of oxidants.”

Reactive oxygen species (ROS), ions that form as a natural byproduct of the metabolism of oxygen, play important roles in cell signaling. These very small molecules include oxygen ions, free radicals and peroxides. However, during times of environmental stress (for example, ultraviolet radiation or heat or chemical exposure), ROS levels can increase dramatically. This can result in significant damage to cellular damage to DNA, RNA and proteins cumulating in an effect called oxidative stress.

One major contributor to oxidative stress is hydrogen peroxide, converted from a type of free radical that leaks from the mitochondria as it produces energy. While the cell has ways to help minimize the damaging effects of hydrogen peroxide by converting it to oxygen and water, this conversion isn’t 100 percent successful.

Ideker and first author Ryan Kelley used the rich functional genomics toolbox of yeast to identify pathways involved in the cell’s adaption to hydrogen peroxide. Adaption (or hormesis) is an effect where a toxic substance acts like a stimulant in small doses, but is an inhibitor in large doses.

To shed light on the molecular mechanisms of adaptation, Ideker and Kelley designed a way to identify genes involved in adaptation to hydrogen peroxide. They elicited adaptation by pre-treating cells with a mild dose of hydrogen peroxide, followed by a high dose. They observed that the cells undergoing this adaptation protocol exhibited a smaller reduction in viability than cells exposed to only an acute treatment protocol (in which about half of the cells died.)

To figure out which genes might control this adaptation mechanism, Kelley and Ideker ran a series of experiments in which cells were forced to adapt while each gene in the genome was removed, one by one covering a total of nearly 5,000 genes. By systematically removing genes, they identified a novel factor called Mga2 and discovered that this transcription factor is essential for adaptation.

“This was a surprise, because Mga2 is found at the control point of a completely different pathway than those which respond to acute exposure of oxidative agents,” said Ideker. “This second pathway is only active at lower doses of oxidation.”

This finding may explain recent studies suggesting that eating less may, in fact, raise ROS levels and, in doing so, provide protection from acute doses of oxidants. This is counter to the hypothesis that caloric restriction extends lifespan in some species because it reduces ROS produced as a by-product of the energy regenerated by mitochondria.

“It may be that adaption to oxidative stress is the main factor responsible for the lifespan-expanding effects of caloric restriction,” said Ideker. “Our next step is to figure out how Mga2 works to create a separate pathway to discover the upstream mechanism that senses low doses of oxidation and triggers a protective mechanism downstream.” Further efforts to understand this process may have broad implications on models of aging and disease.

HOW WILL MY HEALTH BE THIS YEAR

The following tips will be helpful in achieving this target: 1. Never fast Some of us think that cutting down on the meals or fasting will help in reducing the weight. This is not correct and can prove to be dangerous sometimes. Fasting might lead to lowering of blood pressure and may lead to heart related problems. Any weight loss gained by way of fasting cannot be sustained long enough and once you discard fasting, the probability of putting on weight is more. 2. Eat breakfast, and do not skip meals Eat more often to avoid a completely empty stomach, which can make you overeat at your next meal. Instead of skipping meals, it is better to eat four or six small meals or snacks, with a space of 3 to 5 hours between each meal. 3. Don’t deprive yourself Many of us tend to curb our instincts in a conscious effort to reduce the weight. It is better that you have small portions of our favorite food, which may be high in calorie content, once in a while so that you don’t get frustrated and end up binging. 4. Drink plenty of fluids – especially water Drink water and lots of it every day. Diet sodas and mineral water are ideal choice of fluids than just water. Fluids not only quench the thirst but also reduce the appetite. Lesser appetite means lower intake of food. Fruit juices are also categorized under fluids but can add more calories. Hence, be choosy in choosing the fluids. Coffee and tea are good. If you can take these beverages with artificial sweeteners and low calorie creamer instead of milk, that would be ideal. 5. Watch out for low-fat foods Cutting fat from your diet makes sense as fat is the most concentrated source of calories. Be on the lookout for low-fat foods such as dairy products. Also ensure that foods claiming to be low in fat content or not supplemented with sugar, which, in turn, will not yield any results. Again, do not attempt to cut all the fat out of your diet. It has been discovered in research that people are able to stay on diet longer and are better able to maintain their weight loss when their diets allow at least some foods that contain fat. 6. Downsize your portions The quantity of food we intake, either at home or at a restaurant, needs to reduced in a conscious effort. When eating at home, check the portion size of the food you enjoy eating and reduce the content by about one-fourth or one-fifth than you normally eat. While eating at restaurant, reduce the temptation to clean up the plate. By doing so, you can see the difference in your waistline over a period. By following these six simple steps, which have yielded definite results to many people, one can reduce the weight safely and naturally.

Researchers at the London School of Hygiene and Tropical Medicine have found that watching your weight isn’t just about improving your health. It can have an impact on climate change. In their study, published in the April edition of the International Journal of Epidemiology, they found that maintaining a healthy body mass index (BMI) can lower greenhouse emissions. The researchers calculated that a lean population of a billion people would emit 1,000 million fewer tons of greenhouse gas emissions from food production and car travel per year. A population in which 40 percent of the people are obese , like the U.S., requires 19 percent more food energy for its total energy expenditure. Also, less energy is required to transport slim people. “When it comes to food consumption, moving about in a heavy body is like driving around in a gas guzzler,” say the authors. “The heavier our bodies become, the harder and more unpleasant it is to move about in them and the more dependent we become on our cars. Staying slim is good for health and for the environment. We need to be doing a lot more to reverse the global trend towards fatness, and recognize it as a key factor in the battle to reduce emissions and slow climate change,” they conclude. In nearly every country in the world, the average BMI is rising. Globally, there are more than 1 billion overweight adults—at least 300 million of them obese. Obesity and overweight pose a major risk for chronic diseases, including type 2 diabetes, cardiovascular disease, hypertension and stroke, and certain forms of cancer. The key causes are increased consumption of energy-dense foods high in saturated fats and sugars, and reduced physical activity
