[헤럴드경제=고재우 기자] Mr. Park (30), an office worker, is a maniac for nail art. She used to go to nail salons and switched to ‘self-nails’.

Mr. Park said, “If you get a service from a professional shop, 100,000 won is standard.” “A gel nail lamp is essential for nail art. There are as many as four items, including products I bought myself and gift items I received from the shop.”

These days, nail art is popular among people in their 20s and 30s, like Park. A must-have for nail art is the gel nail lamp. A lamp that hardens gel nails that have been painted or attached to the nails. With the popularity of ‘self-nails’ at home, there are many gel nail lamps sold for home use.

If you enjoy nail art, there are things you should keep in mind. A shocking study has found that gel nail lamps can cause skin cancer.

A research team led by Ludmil Alexandrov at the University of California, USA recently published a study on the effect of UV drying equipment for gel nails on the occurrence of skin cancer through the international journal Nature Communications.

First, the research team irradiated adult skin keratinocytes, human foreskin fibroblasts, and mouse embryonic fibroblasts with a UV drying device (ultraviolet rays of 340 to 395 nm) commonly used in nail salons.

As a result of the study, 20 to 30% of cells were killed when irradiated with a UV dryer for gel nails for 20 minutes once, and 65 to 70% when irradiated for 20 minutes three times. In addition, the incidence of cell mutations commonly present in melanoma, a type of skin cancer, increased by up to 12%.

Professor Ludmil Alexandrov said, “We confirmed that DNA was damaged through experiments.” “Moreover, DNA damage was not repaired over time, and we saw mutations occur every time it was exposed to a UV drying device for gel nails.” .

“Long-term epidemiologic studies will be needed before concluding that the use of UV dryers for gel nails increases the risk of skin cancer,” he added.

Nelzeil lamps for professionals have excellent performance and require relatively little exposure time, but products that are popularly purchased these days require exposure to the lamp for a long time compared to professionals. There are high-priced products in the 100,000 won range and low-priced products under 10,000 won.

Mr. Park, who enjoys doing self-nails, said, “I use it several times to harden it. Since I am not an expert, I make mistakes and lack of skills, so I have no choice but to use it several times every time I use it.”

Meanwhile, as non-face-to-face activities have increased since the spread of COVID-19 and interest in nail beauty has grown, the number of people enjoying self-nails is greatly increasing. The industry estimates that the self-nail market will reach about 200 billion won as of last year.

Analysis of 72,498 men diagnosed with erectile dysfunction between 2006 and 2020

[헤럴드경제=장연주 기자] A new study is drawing attention as it shows that phosphodiesterase 5 (PDE5) inhibitors, such as Viagra and Cialis, are helpful for heart health.

According to the Internet edition of the Daily Mail, a daily British daily, on the 19th, a research team led by Professor Robert Cloner, a cardiovascular specialist at the University of Southern California, USA, found that people who used PDE5 inhibitors for erectile dysfunction treatment had a lower cardiovascular disease risk and all-cause risk than those who did not use PDE5 inhibitors. Research has shown that the risk of premature death is low.

The study analyzed the medical records of 72,498 men (average age 52 years) who were diagnosed with erectile dysfunction between 2006 and 2020.

Of these, 23,816 had used PDE5 inhibitors and 48,682 did not.

Overall, PDE5 inhibitor users were significantly less likely to develop heart health problems than nonusers.

PDE5 inhibitor users had a 17% lower risk of heart failure and a 15% lower risk of coronary revascularization due to narrowing or blockage of the coronary arteries that supply blood to the heart.

Heart failure is a phenomenon in which the function of the left ventricle of the heart, which pumps blood throughout the body, fails due to abnormal structure or function of the heart, resulting in insufficient blood supply to all organs and tissues in the body.

In addition, the incidence of angina pectoris, which is caused by a clot in the coronary artery and blocking blood and oxygen to the heart, was also reduced by 22%.

Users of PDE5 inhibitors had a 25% lower risk of premature death from all causes during the study period.

The research team explained that the results of the study took into account other variables such as race, height and weight.

PDE5 inhibitors relax the muscles in the penis, increasing blood flow to help erection. It is also known to improve oxygen flow throughout the body by increasing blood flow to the heart arteries that pump blood throughout the body.

Along with this, there are also research results that increase blood flow to the brain and help prevent dementia.

However, since PDE5 inhibitors are approved for the treatment of erectile dysfunction, doctors do not recommend off-label use.

The results of this study were published in the latest issue of the Journal of Sexual Medicine.
