Water offers best therapy for skin

Water may act as a weapon against ageing, and help keep wrinkles at bay, according to a study.

Scientists have recently identified 1,500 genes that determine how long people can keep their youthful looks, and found that there are eight ways in which skin ages, each controlled by different sets of genes.

However, one of the most important aspects is how well the skin gathers and retains water.

According to a study, up to 700 genes that help keep the skin hydrated become less active and less able to retain water as the cells get older, and thus lead to wrinkles.
Another factor is the levels of collagen, a molecule that gives the skin structure and strength. The genes that degrade it become overactive in older age, which also leads to wrinkles.

It has been found that there are about 40 genes that accelerate breakdown.
Wrinkles are also attributed to inflammation, which is affected by about 400 genes, and becomes more active with age.

Alcohol ups risk of prostate cancer

Researchers at the University of California San Francisco (UCSF) say that heavy, daily drinking increases the risk of high-grade prostate cancer.

Dr Zhihong Gong, who led the study, also says that heavy drinking makes the drug finastride ineffective in reducing prostate cancer risk.

The UCSF team came to this conclusion after examining the associations of total alcohol, type of alcoholic beverage, and drinking pattern with risks of total, low- and high-grade prostate cancer.

For their study, the researchers used data from more than 10,000 men participating in the Prostate Cancer Prevention Trial (PCPT).

New kit to check kids’ drug abuse

Parents would now be able to detect whether their kids are using drugs with just a lock of their hair.

The 40-pound testing kit can detect seven drugs, including cannabis, cocaine, Ecstasy, and heroin.

According to Biosciences, the American manufacturer, it can detect molecules that remain in the hair for up to 90 days, “equipping parents with a valuable new tool for combating substance abuse”.

The test is much more reliable than saliva and urine tests. Moreover, shampoo, bleach or other external chemicals do not affect the results.

Users of the tests, available online, send off a sample for testing and then receive a report on the amount of each drug detected as well as the frequency of use.

Inflammation may cause Alzheimer’s

A new study has revealed that inflammation might lead to development of Alzheimer’s disease.

Two research studies published by William A Banks has shown how inflammation triggers disease, and how can it be treated.

It is believed that the toxic levels of amyloid beta protein, the substance responsible for Alzheimer’s disease, accumulate in the brain because a pump that pushes it into the blood and past the blood-brain barrier malfunctions.

The blood-brain barrier is a system of cells that regulates the exchange of substances between the brain and the blood.

The blood-brain barrier transporter known as LRP is the pump that removes amyloid beta protein from the brain and into the bloodstream.
