But when scientific studies provide medicines and treatment in the real world? More often than it seems, given the thousands of projects underway in laboratories around the world. ¿
What were some of the most interesting developments emerged in 2014? I’ve rounded up some of the advances in health from run to celebrate the achievements in medical science.
The takeaway? These advances could affect your day to day life for the better.
common drinks protect your memory
Some of us can not get out of bed in the morning without our caffeine! There is no doubt that it is addictive, but numerous studies have suggested that caffeine has many health benefits, such as improving concentration and focus, reduce the risk of liver disease, and cut the risk of mouth cancer throat 50 percent.
While not drinking cup after cup throughout the day, “everything in moderation” motto works in your favor.
New research suggests that caffeine after a training session can help improve long-term memory. Whatever new task you are doing (try a new recipe, playing a new card game) or a new route you are navigating (at your church or a restaurant for dinner), along with a cup of coffee or tea caffeine helps strengthen your ability to remember.
This is an important finding as we look at “neuroprotective” -. Ways to strengthen the brain’s neurons or connections, and protect against cognitive decline associated with age
Researchers at Johns Hopkins and the University of California, Irvine compared test results from participants on skills thinking and memory with different amounts of caffeine and a placebo. Doses of 100, 200 and 300 mg of caffeine were consumed to measure performance, with doses of 200 mg demonstrating the greatest benefit when consumed after the training session.
To put dose into perspective, an average cup of coffee contains eight ounces of 95 mg of caffeine. The same amount of black tea contains anywhere from 14 to 70 mg. peak mental capacity does not come with high caffeine intake throughout the day, so take note!
The Food and Drug Administration (FDA) estimates that the average American consumes 300 mg of caffeine a day (two to four cups of Joe), with the main sources being coffee, tea and The drinks.
“We have always known that caffeine has cognitive effects of improvement, but their particular on strengthening memories and make them resistant to oblivion effects has never been examined in detail in humans,” says Michael Yassa , lead author of the study. “It Presented for the first time a specific effect of caffeine on reducing miss more than 24 hours.”
Caffeine is like a clarion call to your brain. It is a stimulant that also works to block a chemical called adenosine, which normally prevents the release of excitatory brain chemicals. Adenosine helps calm and still your thoughts so you can relax or sleep.
When caffeine blocks adenosine, brain stimulation occurs, and gives you that surge of energy to improve mental performance and protect against mental decline related to age.
longest in the history of conservation lungs for transplantation
The preservation of organs for transplantation is a complicated issue, so the preparation of a patient for the operation has to happen it is the short term.
In 2014, transplant specialists at the University Hospital of Leuven in Belgium were able to preserve donor lungs outside a human body for 11 hours, marking the longest time in medical history. The long shelf was crucial because the patient needs a liver transplant immediately prior to lung transplantation. A lung transplant can only succeed if the liver is still functioning properly.
In this case, the lungs were not put on ice – the usual procedure – but keep with a machine called the OCS lung that provides continuous washing and oxygen at room temperature without negative effects. The machine also gives an analysis of the quality of the lung and may improve lung function in anticipation of transplantation.
There is a similar machine to the kidneys. transplant results have shown that the new technique preserves the best older and helps kidneys work better after the operation that have not been on the ice.
The OCS lung machine is available in Europe and Australia, and is expected to begin clinical trials in the United States soon.
There are better food choices to protect your heart
You could be convinced that a regular glass of wine every night is good for the heart. However, recent findings call into question many studies touting alcohol mild to moderate can protect your heart. It turns out that there are better things to eat and drink adult beverages.
The hard truth is alcohol is a drug that alters the normal function and can lead to unhealthy addiction.
New research from the Perelman School of Medicine at the University of Pennsylvania, data from over 50 studies linking drinking habits and cardiovascular health to more than 260,000 people were examined. There is a specific gene that usually leads to lower alcohol consumption over time due to uncomfortable symptoms. The researchers found that people who carry this gene, on average, have higher cardiovascular health.
The “alcohol dehydrogenase 1B” breaks gene alcohol much faster, causing adverse symptoms such as nausea and a heated face reddened. If you have it, you likely know.
The Perelman study showed that people who consumed 17 percent less alcohol per week have, on average, 10 percent lower risk of coronary heart disease, low blood pressure and a lower body mass index ( BMI). Contrary to previous reports, the researchers concluded that any alcohol exposure has a negative impact on your heart.
You could argue that red wine has been shown to be rich in antioxidants, which are great for your heart. An antioxidant found in red wine, in particular, resveratrol, has received praise from heart protection. But the Mayo Clinic and others say the evidence in support of red wine is unclear.
In view of the investigation of the Perelman School, is much better simply eating grapes or drinking grape juice. Resveratrol is found in grape skin, along with other foods such as blueberries, cranberries and peanuts.
Your best bet is a glass of wine from time to time – nobody wants to feel completely deprived of the small pleasures of life. But try to cover your morning oatmeal or yogurt with grapes and berries instead.
There is clearly a better way to protect your heart.
implant ‘bionic eye’ to restore sight
Technology is changing at breakneck speed and scientific advances can often seem exaggerated, but the replacement body parts are becoming a real choice in medicine today.
Remember the TV series long-term The Six Million Dollar Man , in the 1970s? Former astronaut Steve Austin had his right arm, both legs and his left eye replaced with bionic parts after a plane crash, giving him superhuman strength, speed and vision – and later a Bionic Woman girlfriend
Now surgeons have implanted a prosthetic retina or “bionic eye” to restore vision. This new technology is an effective treatment for late-stage retinitis pigmentosa (RP), a disease that causes most patients are legally blind at age 40. The retinal implant does not provide a complete picture, but it helps people to detect light and darkness and identify people and objects.
The high-tech prosthesis combines a surgical implant, glasses video camera and a unit video processing that is worn on the waist or worn.
When it comes to sight, a healthy retina converts light into small electrical impulses that are sent through the optic nerve to the brain. The brain then decodes them into images.
The bionic eye replaces damaged cells in the retina and allow people perceive patterns of light in the brain. The video camera mounted in glasses capture images and feed signals wirelessly to an implanted near the retina chip. These signals stimulate cells of the retina and produce light in the visual field of the person. The person learns how to interpret these patterns of light, the recovery of visual function.
A number of companies are developing this type of implant, but the results of a small clinical study of 30 people have shown better results so far with the Argus II implant from California Second Sight. Participants were able to recognize large letters, words and phrases, black party, gray socks and white, and walking on a sidewalk without stepping off the curb.
While the bionic eye is directed to a specific eye disease, researchers say marks the beginning of a new era to restore sight devices to address other causes of vision loss.
While science can often seem as if it is removed from our daily lives, these advances demonstrate why health research and development funding is so important -. And how discoveries can make their way to the general public and improve life
