Smokers at greater risk of developing psoriasis

A new study has found that people who smoke have a greater risk of developing psoriasis, a disease which affects the skin and the joints and commonly causes red scaly patches to appear on the skin. Researchers in the US discovered that regular smokers have an increased risk of the skin condition, which only falls back to normal 20 years after quitting. The study, which included 79,000 nurses, also found that people with psoriasis who smoke had a more severe form of the disease.

Scientists develop UV technology to treat cancer

It can be called a medical breakthrough which is guaranteed to bring hope to millions of cancer victims. – a new technology to destroy tumour.
Yes, scientists in Britain have developed the cancer fighting technology which uses beams of ultraviolet light to activate antibodies which specifically attack and destroy tumours, the Daily Mail reported on Tuesday.
“I would describe this development as the equivalent of ultra-specific magic bullets,” lead researcher Professor Colin Self of Newcastle University was quoted bt the British daily as saying.
According to him, the new technique could be used for tumours close to the skin, such as breast cancer, and for any cancer accessible by a light probe. These include stomach and bowel cancers as well as ovarian cancer.
The researchers tested the technology successfully on six volunteers who fell gravely ill at Northwick Park Hospital because the antibodies they activated affected their entire body, driving their immune systems into overload.
To get over this problem, the Newcastle team cloaked antibodies in an organic oil which rendered them inactive until illuminated by UV rays. By using a probe to shine a light on the tumour, the antibodies at the right place in the body were brought to life.
The activated antibodies then caused immune cells in the blood called T-cells to attack the cancer.

Chronic Cough? Get iron in your diet

A study, presented at the scientific meeting of the American College of Chest Physicians in Chicago, suggests that iron deficiency may help explain why some other otherwise healthy, non smoking women have persistent coughs. It was found that a simple iron supplement could clear up the cough. The researchers studied 16 women with chronic cough who were found to have normal lung function, with no signs of asthma or other respiratory disease and no evidence of acid stomach reflux. All had iron deficiencies. Their vocal chords were very sensitive, making them cough and choke easily. These women were given iron supplements and after two months it was found that coughing and signs of inflammation in the mouth of the vocal cords were improved or completely resolved.

Smoking linked to teen alcohol, drug use

Teenagers who smoke are five times more likely to drink and 13 times more likely to use marijuana than those who are not smokers, a study suggests. The report by Columbia University’s National Center on Addiction and Substance Abuse presented further evidence linking youth smoking to other substance abuse and spotlighted research on how nicotine affects the adolescent brain. The report analyzed surveys conducted by the US Substance Administration and other data on youth smokers. It said that smokers aged 12 to 17 are more likely to drink alcohol than non-smokers. Those who became regular smokers by age 12 are more than three times more likely to report binge drinking than those who never smoked.

Garlic-rich diet helps fight cancer

Garlic has long been taught as health booster, but it is never been clear why the herb might good for you. Now new research is beginning to unlock the secret of the odoriferous, bulb. In a recent study published in the proceedings of the national academy of science, researchers show that eating garlic appears to boost our natural supply of an organic substance called hydrogen sulphide. In the later study, performed at the university of Alabama at Birmingham, researchers extracted juice from super market garlic and added small amounts to human red blood cells. The cells immediately begins emitting hydrogen sulphide, the scientists found. The power to boost hydrogen sulphide production may help explain why a garlic rich diet appears to protect against various cancers, including breast, prostrate and colon cancer, say the study authors.

Implant for Parkinson's may hinder self-control

Your brain is supposed to fire a "hold your horses" signal when faced with a tough choice. But a brain implant that stops the tremors of Parkinson's disease may block that signal - a new explanation for why some Parkinson's patients become hugely impulsive.
Scientists have long known that anti-Parkinson medications occasionally spark compulsions like pathological gambling. Research published on Thursday found another treatment, a pacemaker-like brain implant, can trigger a completely different kind of impulsiveness. How different? The drugs leave a subset of patients unlikely to learn from bad experience, like a losing poker hand.
The brain implant doesn't hinder learning. In contrast, those patients can make hasty decisions as the brain loses its automatic tendency to hesitate when faced with conflict, University of Arizona researchers reported online in the journal Science.
In fact, the first patient they studied displayed as alarming example when he saw something across the room he wanted and tried to dash over without his wheelchair. Neuroscientist Michael Frank had to catch the man before he fell.
