New research found that HIV can passes more easily from men to women than previous thought. Before this many expert are strongly believed female vaginal tract presents an impenetrable barrier to AIDS virus if it is injured but a new research proof that is not the facts.
From the study they found the virus is still able to invade vaginal wall. It happen during sexual intercourse and then will give infection to immune system cells. For about four hours the viral particles can move between skin cells and then reach a depth of 50 microns where they got ability to attack immune cells.
Previously ,what has been understand by the scientist AIDS virus only could enter the vaginal tract through an open sore for instance which is caused by the herpes virus. Beside of this the virus might penetrate the single layer of skin cells that line a woman’s cervical canal. that is another theory beside what they already believed but there are no impact on HIV infection rates when an African trial in which women used a diaphragm to block the cervix.
‘A big mistake in this field is the idea that transmission only takes place one way,’ said Prof Hope, who presented the findings today at the American Society for Cell Biology’s annual meeting in San Francisco.
‘We urgently need new prevention strategies or therapeutics to block the entry of HIV through a woman’s genital skin.’ He added.
Yeah! You’re not dreaming. I got this news from Dailymail today report that the scientist just found new fact which is video games can give a boost to an elderly person’s brainpower.That really amazing right?
According to Professor Arthur Kramer who is psychological professor at the University of Illinois our mental function that decline most with age can be improve when playing interactive games. He do the testing to 40 people at the age of 60s to 70s. Most of them were asked to play Rise of Nations games. In this game player need to build cities, maintain an army and not to forget expand their territory.
What he observe the older who play this game became significantly better at ‘executive control’ functions such as the ability to switch between tasks, short-term visual memory, reasoning skills and working memory.
Professor Kramer said: ‘This is the first such study of older adults and it is the first to find such pronounced effects on cognitive skills not directly related to the skills learned in the video game’
So what do you think guys. Don’t you think this is a good news for older?
Do you think weight loss will become easier when we play it with money? How? OK lets say we got paid every time we can reduce our weight. That will encourage us to do more right. This is the fact found by US reseachers.
According to them the weight loss program that pay people with money and let people know they will loss the money that they stand if they fail will motivate people to lose weight compared with more conventional approaches.
Dr. Kevin Volpp from University of Pennsylvania School of Medicine said that many weight-loss programs can’t be success because people always needs to makes sacrifices earlier before got rewards later on. He was looking for an effective way to overcome obesity which is a growing problem that caused very serious health risks.
After their study Volpp urge to create a different reward system program by rewards people in the present. He said ” The studies were highly effective at producing short-term weight loss, but when the money stopped flowing, the weight began to creep back on.”
“We need to establish whether they can be effective in sustaining weight loss as well,” He added
Many women think that by cut the carbs will help them to lose some weight but not many of them know that could make they lose memory too.
We need to keep in mind, Carbohydrates are such an important source of energy for our brain. Scientists found by practice Atkin-style diet for a week our mental performance will drops.
“The study demonstrates that the food you eat can have an immediate impact on cognitive behaviour. The popular low-carb and no-carb diets have the strongest potential for negative impact on thinking and cognition.”said the person who lead this research Dr Holly Taylor. Atkin diet is very popular in early 2000s.
The reseacher believe that low-carb diets will cut down the amount of glucose, or blood sugar, which is bring to the brain and used by nerve cells for energy. A low-carbohydrate diet means less fuel to power the brain cells.
Dr taylor explained ‘Although this study only tracked participants for three weeks, the data suggest that diets can affect more than just weight,’
‘The brain needs glucose for energy and diets low in carbohydrates can be detrimental to learning, memory, and thinking.’
Latest study showed that by walking about an hour a day can low down the risk of getting breast cancer for a women.So far about 40,000 British women diagnosed with breast cancer every year . This disease already killed around 12,000. It affects one in nine women at some point in their lives.
The study done by Nagoya City University in Japan. They tracked 30,000 women over 12 years to monitor their lifestyle habits and risk of cancer. Result from this study has been published in the journal Cancer Epidemiology, Biomarkers & Prevention, mention that those who walked at least an hour a day, and then went jogging, swimming or to the gym for another hour once a week, were substantially less likely to have cancer.
Actually by maintaining a healthy body weight is one of the best ways to reduce the risks of breast cancer according to spokesman for Cancer Research UK.
So that maybe a good news for women because walking an hour a day not really burden but keep in mind sleeping less than seven hours a night wiped out the benefits and actually increased the risk of cancer. Just be careful.
