A report released by the WHO and UNAIDS last year stated that studies show that male circumcision can lower the risk of transmission of HIV from female to male. There is half a chance that circumcised males can acquire HIV from women as compared to their uncircumcised counterparts. But the study, as of the present, is inconclusive when it is the other way around – the protection that women can get from their circumcised partners. The study is also limited to the traditional sexual intercourse e.g. penile – vaginal sex.
Although male circumcision can reduce HIV transmission risks from females to males, it is stressed that it is not a hundred percent protection. It only lowers the risk of transfer not totally prevent it.
Cholesterol is always associated with heart disease. For those who care about their health, monitoring the level of cholesterol in their body is an ordinary thing. The ideal total cholesterol level should be 240 mg/dl high cholesterol. But recent findings suggest that we should also be aware of the size of the cholesterol in our body, may it be good or bad cholesterol.
Anticipation of heart related diseases cannot be relied upon the cholesterol level alone. A high percentage of our cholesterol is carried by high-density lipoproteins (HDL). The size of the HLD may determine the efficiency of good cholesterol or the adverse effect of a bad one. If the HDL is relatively small, cholesterol can easily pass through blood vessels thus limiting the efficiency or the adverse effect of said types of cholesterol in our body. And this concern is something that can be dealt with. A healthy lifestyle, such as regular exercise and proper diet may improve the size of our cholesterol.
Scientists have figured out how mice that lose the ability to walk after a spinal-cord injury can regain it, a finding that could someday help human patients, Scientific American reports. When the long nerves that run from the brain to the base of the spine were severed, shorter nerves in the area were repurposed—not regrown, as was previously believed.Â
Have you ever tried riding a rollercoaster? You just can’t stop yelling at the top of your lungs because of its challenging ups and downs. One moment you’re up there, the next minute you’ve almost kissed the ground. It may be an adrenaline-pumping experience for many, but for bipolar patients, living life on a constant rollercoaster ride is no fun at all.
People suffering from a bipolar disorder or the so-called manic depression are living life on an emotional rollercoaster. They can be extremely happy for one moment then for the next few hours they can be dreadfully depressed. There seems to be no in between.
It’s sad to know that there is no cure for bipolar disorder but good thing there is a way to treat it effectively. Doctors treating patients with bipolar disorder have been using lithium carbonate for 50 years now however, it’s found not effective for everyone. To solve this problem, doctors
started giving the patients anti-depressant and anti-psychotic drugs.
For patients with bipolar disorder, life is never easy for it is a series of extremes. But with the advancing medical technologies we can just hope that soon the rollercoaster ride for them will be completely over.

Fibromyalgia or chronic fatigue syndrome has long been one of the most complex medical situations that has baffled many doctors. Recent years has shown little improvement in the cure of the disease although the only way doctors dealt with the sickness was through trial and error. Read the rest of this entry »
Not everyone is a fan of needles. In fact, there are probably more people who are averse to having needles stuck into their skins. This isn’t surprising as needles are most always associated with pain, sickness, and medication.
Since it’s a part of many medical procedures however, there’s no way around getting shots until new ways of dispensing specific medicines or vaccines can be found. This might soon change though thanks to the medical researchers at Georgia Tech and Emory University who have teamed up to create a flu vaccine that is painless, convenient, and hassle-free.
“We’re developing a technology we like to call microneedles. These are needles that we make by using the technology that’s used to make integrated circuits for computers,” said Georgia Tech Professor Mark Prausnitz.
Prausnitz says microscopic needles are coated with flu vaccine that can be barely seen or felt. It allows the vaccine to get into the body.
“Without those tiny needles, if you put the flu vaccine on your skin, none would go in,” according to Prausnitz.
Emory University’s Dr. Ioanna Skountzou says the technology is promising and easy to use. “This is something we hope to put in practice in the very near future. You can apply the patch yourself like a band aid, keep it on for only a short period of time and then dispose it.”

A Harvard Medical School study indicate that it may be possible to stop type 1 diabetes and renew the insulin-producing beta cells that are destroyed by the disease. The scientists used a mix of three drugs designed to tame the out-of-control immune response attacking the pancreas, and an enzyme called alpha 1 anti-trypsin, which is normally produced by the body to ease inflammation.. This has only been tested on mice so far but trials with human patients will be run soon.
At the same time, progress is also being done towards a cure for type 1 diabetes in Sydney, Australia. Scientists from Westmead Hospital transplanted islet cells from a donor’s pancreas into patients’ livers, where the new cells began to produce insulin. This procedure was successfully done on eight patients and the results were very promising: the patients’ need for insulin shots dropped dramatically, to zero in some cases.
Recent studies involving the use of radiofrequency ablation in treating liver cancer have yielded positive results. Radio-frequency ablation is the removal of unwanted tissue from the body using radio-frequency energy. This method is also used in treating coronary diseases, varicose veins and in somnoplasty.
Although the study was limited to tumors less than four centimeters, the application of radiofrequency ablation was effective on patients with liver cancer where surgery was not possible.
In the said study conducted in Charité, Campus Benjamin Franklin, Berlin, Germany complete destruction of tumors occurred in 66 out of 67 cases where multipolar radiofrequency ablation was used to treat liver cancer. Fifty-two percent of the patients are tumor free, while seventy-eight percent are still living after four years. Only in eight cases that re-ablation was needed from the 67 cases.
Vitamin D is significant when it comes to the development of our organs. This vitamin is the regulator of calcium and phosphorous which is essential for the development of our bones. Vitamin D is also been said to be able to play a role in preventing diabetes and coronary diseases. The most recent findings on the benefits of vitamin D, though not yet extensively identified, is its ability to prevent the development of cancerous cells.
Calcitriol, a hormone of vitamin D is said to cause the death of cancerous cells. Several studies show that regular intake of vitamin D can deter the development of colon, breast, ovarian cancer and even prostate cancer. The link between vitamin D and colon cancer has produced the most interest among scientists and those in the medical field because it has shown a great potential.
It has always been believe that atherosclerosis which is the buildup of plaque in the arteries, was irreversible. But this year, heart experts has done something that was thought to be almost impossible, they were able to shrink the fatty clogs blocking the heart’s arteries of patients by around 7 percent only with the use of maximum dosage of Crestor which is a cholesterol-lowering medication. Heart medications before are only taken to slow or stop the narrowing of arteries. But this new finding raises the possibility that you can actually reverse the plaque accumulation that starts even as early as childhood.
