A study claims that a 60-second "red light" treatment may increase a man's sexual desire!

The treatment involves beaming light from a special torch through the skin of the penis after injecting a compound into the area.

The compound, known as NORD-1, reacts to light by releasing nitric oxide, a gas that helps blood vessels dilate - boosting blood flow to the organ and improving erections.

And a new study shows the technique is effective in animals - and the Japanese scientists behind it believe it could work well for men who don't respond to drug treatments. They hope to start human trials in the next two years.

Medications such as Viagra, Cialis and Levitra help some men by dilating tiny blood vessels in the pelvic area, allowing more blood to reach the penis. But about a third of the men who take these pills don't feel any improvement.

In these cases, the only other options are to inject the drugs directly into the penis — which can be painful and difficult to self-administer — or to use a pump that manually increases the blood supply to the penis.

Red light therapy could be another option, according to findings of a study recently published in the International Journal of Men's Health.

The tests involved injecting NORD-1, a synthetic chemical that only releases nitric oxide (through a chemical reaction) when exposed to red light, into the genitals of ED mice. And simply injecting nitric oxide itself into the body to dilate blood vessels is not a solution, as it can cause unwanted side effects, such as low blood pressure.

But this way, nitric oxide is only released when the light hits the genitals, making it safer. (Unlike other injectable treatments for erectile dysfunction, this is given every now and then, not every time a man has sex.)

Researchers at Nagoya City University in Japan monitored changes in the rodents after injecting NORD-1 into the penis and flashing a red light for just 60 seconds.

Four weeks later, the results showed a significant improvement in the frequency and duration of erections after the red light treatment.

Tests also showed that erections improved even after nerve damage similar to what happens in men who underwent prostatectomy due to cancer.

This raises hopes, the researchers said, that men whose sex lives have been affected by prostate cancer surgery can, in the future, revive their libido using red light therapy.

Professor Paul Chazot, a scientist at Durham University who is researching red light therapy in dementia (to improve blood flow to the brain), said: 'The release of nitric oxide could be beneficial in many clinical situations - including erectile dysfunction. So it is likely that "It would be useful. But these findings are in mice and may not extrapolate well to humans." Source: Daily Mail

Detection of the most prevalent diseases among men and women in Egypt

The Dean of the Oncology Institute at Cairo University, Mohamed Abdel-Moati Samra, confirmed that the most common oncological disease in Egypt among women is breast tumors, with a rate of 25%, while men have lung and liver tumors.

He stressed that there are changes that occur as a result of controlling some pathogens, such as smoking, as it is a major factor in the incidence of lung, throat and larynx tumors, and the incidence of lung tumors is 12 times that of non-smokers.

The Dean of the Oncology Institute added that there are some tumors linked to viruses, such as liver tumors, stressing that among the achievements of the presidential initiative to eradicate hepatitis C, as we do not only protect the liver, but we also protect that a hepatitis C patient has a high incidence of liver cancer by using hepatitis C treatment and compulsory vaccination campaigns. Against C virus, it reduced the incidence of liver tumors.

The Dean of the Oncology Institute continued that there is a relationship between some types of viruses and the incidence of cervical cancer. From this standpoint, early detection of women is important in granting some vaccinations and treatments that reduce the incidence of cervical cancer. Excessive exposure to sunlight has a close relationship with the incidence of tumors, especially for white-skinned people, specifically in European countries because it causes skin cancer, explaining that the intended exposure here is exposure to sunlight for long hours and for many years.

Russian military scientists create artificial limbs and implants made of carbon fibres

Military scientists from the IRA Military Innovations Complex in Anapa, southern Russia, have devised a method for producing and implanting internal prostheses made of carbon fibres.

They are developing ways to test it for biocompatibility. This was reported by the Russian agency "TASS", quoting the first soldier, engineer in the third company of the military-scientific complex, Konstantin Alexandrov.

He said: "It means medical products made of carbon composite materials and above all, prostheses and implants. The composite material is produced from carbon fibers by pressure and the effect of high temperatures. Its advantage is that bone tissue grows thanks to the presence of a porous material. After passing "Some of the time it is difficult to distinguish even on X-rays where the bone is and where it has been restored with the help of a prosthesis. We are now working on methods for biocompatibility testing, which will then be tested on laboratory animals."

According to the military researcher, carbon composite materials are widely used in various fields of industrial production, including missile production, the development of machine tools, and others. There is currently no experience of using such materials for medical purposes in the world. In cooperation with the "Ural" Scientific Research Institute, which produces this type of composite material, specialists have developed a prosthesis for the femoral neck and an implant for part of the brain skull. The researchers plan to complete work on the project at the end of 2023 or the beginning of 2024.

In addition, the Military Complex of Innovations has developed, using 3D printing, a method that is unparalleled in the world to produce medical devices with a special design, based on personal requests received from patients. Source: TASS
