New laser therapy for easy tattoo removal

Dermatologists are now discovering new laser therapies for enhancing tattoo removal treatment.
Tattoos, which may affect a person’s skin, can be quite difficult to treat or remove.

While lasers have been used to remove tattoos for several years, the procedure requires multiple treatment sessions (typically six to 10 treatments or more) and treatments are painful, requiring a few weeks of healing time between procedures. 

According to dermatologist Arielle N B Kauvar,  clinical professor of dermatology at New York University School of Medicine, the process of tattoo ink removal is inefficient since every colour of ink absorbs different wavelengths of light, requiring the use of multiple lasers. Some colours – such as yellow, orange, turquoise or fluorescent ones – remain more difficult to treat.

 One new study uses the Q-switched YAG laser to treat a tattoo four times in one day. These four separate treatments are administered at 20-minute intervals and have demonstrated much faster clearance of tattoo inks.

Other research involves the use of the fractional ablative laser in conjunction with traditional tattoo-removal lasers to speed up clearance – resulting in as much as 50 percent tattoo ink removal in just one treatment session.

 “The biggest drawbacks to laser tattoo removal are the time, expense, pain and healing involved,” said Dr Kauvar.

 “The newest techniques being investigated are designed to reduce the number of treatment sessions required to remove a tattoo,” he added.

Decaf coffee may help boost memory function

Drinking decaffeinated coffee could improve an individual’s memory, a new study has suggested.
According to the researchers of the study, the drink could improve the memory of those suffering from diseases of the brain or age-related forgetfulness, and may even prevent symptoms from appearing in the first place.

They tested their theory by giving a dietary supplement with the same properties of decaffeinated coffee to mice with type 2 diabetic mice.

The disease lowers glucose levels in the brain, causing impairment in memory and other brain functions.

As opposed to a placebo, mice treated with the supplement, for five months showed raised levels of glucose.

“This is the first evidence showing the potential benefits of decaffeinated coffee preparations for both preventing and treating cognitive decline caused by type 2 diabetes, ageing, and, or neurodegenerative disorders,” he Telegraph quoted Giulio Maria Pasinetti, the lead researcher from Mount Sinai School in New York as saying.

Coffee is linked to a higher risk of heart disease and stroke, but Pasinetti said these effects were most likely due to the caffeine content in the drink.

Solid finger food may help babies avoid obesity

Infants outgrowing a liquid diet who give themselves finger food rather than being spoon-fed puree are likelier to eat healthily and avoid getting fat during weaning, reports a study released Tuesday.
Researchers found that the technique, known as "baby-led weaning," led to a child expressing a clear preference for pasta, rice and other carbohydrates over sweets, thus helping to cement a foundation for eating the right foods.

Experts and parents alike have long debated over when and how to help an infant make the transition from mother's milk or the bottle to a solid-food regimen.

Many studies have already concluded that self-feeding with finger food is fine for most infants.
But what impact this approach might have on longer-term taste preferences and a child's overall health has until now been less clear.

Finger food works because it accustomises children to the textures of what they will be eating later, the researchers speculated.
