Carrots help boost vision


In a five-year study, scientists in Belfast and Waterford showed that the intake of high levels of both carotenoids - rich antioxidants found in fruit and vegetables - preserved macular pigments, slowing down the progression from early to late age-related macular degeneration (AMD).

AMD is an incurable eye disease which causes blurring of central vision because of its effects on the macula, the central part of the retina.

To reach the conclusion, Professor Usha Chakravarthy, from the Queen's University Centre of Vision and Vascular Science, looked at nutritional supplements for patients with AMD and found they helped sharpen vision.

Skin cancer cream for wrinkles' cure

US scientists led by Dr Dana Sachs, of the University of Michigan Medical School, have found that besides reducing potentially cancerous skin patches, Fluorouracil ointment, also known as Efudex, can mend the damage seen on sun- exposed faces.

Sachs said: “Undoubtedly, there will be patients who desire a therapy such as topical fluorouracil for cosmetic purposes given the relatively low cost.”

The cream, which is used to treat actinic keratoses, a precancerous condition, appears to cause a wound-healing response that leads to an increase in collagen production, which then improves the appearance of wrinkles, reports The Daily Express.

Curd can help lose excess weight

Probiotics are the so-called ‘good’ bacteria found in yogurt as well as in over-the-counter dietary supplements that help in the digestion of food.

New research from the Stanford University School of Medicine and Stanford Hospital & Clinics suggests that patients who take probiotics after the gastric-bypass procedure tend to shed more pounds than those who don't take the supplements.

"Surprisingly, the probiotic group attained a significantly greater percent of excess weight loss than that of control group," said John Morton, MD, associate professor of surgery at the medical school who wrote the paper with lead author Gavitt Woodard, a third-year medical student, and five other medical students at the Surgery Center for Outcomes Research and Evaluation in Stanford''s Department of Surgery.

Pregnancy stress can damage baby's brain

The researchers behind the exhibit, from Imperial College London, hope that it will raise awareness among families of the importance of reducing levels of stress and anxiety in expectant mothers.

Reducing stress during pregnancy can help prevent thousands of children from developing emotional and behavioural problems, they said.Visitors to the exhibition will have the chance to play a game that shows how a mother's stress can increase the heart rate of her unborn baby.

They will also be able to touch a real placenta, encased safely in plastic. The placenta is crucial for foetal development as it usually protects the unborn baby from the stress hormone cortisol.
However, when the mother is stressed, the placenta becomes less protective and the mother's cortisol may have an effect on the foetus, said an Imperial release.

Lifestyle stress raise infertility problems

A University of Adelaide (U-A) study has advised infertile couples to seek advice about their lifestyle before embarking on IVF treatment or other assisted reproductive technology.

Gillian Homan, fertility nurse specialist from the University's Robinson Institute, says that couples experiencing infertility should understand the role their own lifestyle can play in helping them achieve their goal of a healthy baby.

The reproductive health researcher surveyed 20 new patients from the Adelaide fertility clinic Repromed to gauge their perception of how lifestyle affects fertility.While the evidence of the impact of weight on fertility is very strong, only half of theoverweight women in this study considered their own weight to be a risk factor for infertility.

Turmeric root cuts breast cancer risk

Studies conducted in the past have suggested that a combined oestrogen and progestin hormone replacement therapy increases postmenopausal women’s risk of developing progestin-accelerated breast tumours.

“The results of our study show that women could potentially take curcumin to protect themselves from developing progestin-accelerated tumours," said Salman Hyder, the Zalk Endowed Professorship in Tumor Angiogenesis and professor of biomedical sciences in the College of Veterinary Medicine and the Dalton Cardiovascular Research Centre.

The study conducted using animal model showed that curcumin delayed the first appearance, decreased incidence and reduced multiplicity of progestin-accelerated tumours.
Curcumin also prevented the appearance of gross morphological abnormalities in the mammary glands.
