Green tea could lower bad cholesterol

Green tea may be effective in reducing ‘bad cholesterol’, a study has found.
Green tea contains antioxidant compounds called catechins, which many studies have tested for their effect on cholesterol even though the studies have been small and had conflicting results.

For the new study researchers at Western University of Health Sciences in Pomona, California, pooled the results of these clinical trials, involving a total of 1,415 adults.
Participants in the trials consumed green tea beverages, capsules, or placebos daily. Benefits were found among people who had high cholesterol levels at the beginning of the study. However, the researchers still sound a word of warning.

“If someone is already taking medication for their cholesterol, they should stick with it and not try to trade it for green tea, either capsules or the beverage,” CBS news quoted study author Dr. Olivia Phung as saying.

According to the study, the use of herbal supplements like green tea is only one of the strategies to lower cholesterol, along with medication and lifestyle changes.
The study was published in the Journal of the American Dietetic Association.

Regular fish oil decreases osteoarthritis pain

A two-year study showed that it can reduce the pain and inflammation caused by osteoarthritis. Researchers from several universities and hospitals in Australia and Tasmania studied 200 patients with an average age of 60.

They discovered that those on a low dose had double the reduction in knee pain of patients on higher doses and also had significantly greater improvements in mobility, the Daily Mail reported. In their report the researchers said that ‘high doses were not superior to low doses’ but they were still unsure why.

Roundworms may contain secrets of wound healing

Scientists have claimed that roundworms may be the ideal laboratory model to learn more about the complex processes involved in repairing wounds and could eventually allow them to improve the body’s response to healing skin wounds. Andrew Chisholm and his team from the University of California, San Diego have discovered genes in the laboratory roundworm C. elegans that signal the presence of surface wounds and trigger another series of chemical reactions that allow the worms to quickly close cuts in their surfaces that would turn fatal if left unrepaired.

 The scientists have reported that these two findings and a third discovery they made in the worms, involving genes that inhibit wound healing, could allow them to design ways to improve the healing of cuts and sores by possibly blocking the action of these inhibitory genes or finding ways to enhance the chemical signalling and wound healing process.

Chisholm thinks that the lowly roundworms have a delicate surface susceptible to injury and a rapid wound response mechanism that keeps their surface wounds from being fatal.
“They have a hydrostatic skeleton in which the skin and muscles are under pressure to allow the animal to stay semi-rigid, so when you jab a worm with a needle it will, in effect, explode,” he said.

EU sounds cry of alarm over resistance to antibiotics

The European Union warned Thursday of a sharp rise in deaths across the 27-nation bloc due to bacteria becoming resistant to antibiotics.

With some 25,000 Europeans dying each year from infections caused by drug-resistant bacteria, European health commissioner John Dalli said "we need to take swift and determined action if we do not want to lose antimicrobial medicines" for humans and animals.

Antimicrobials include antibiotics and can also be used as disinfectants and antiseptics.
Data issued by the European Centre for Disease Prevention and Control show resistance to pathogens which often cause pneumonia and urinary tract infections in hospitals on the rise, at a cost of over 1.5 billion euros ($2.0 billion) in care and productivity losses.

A five-year EU plan to contain the risk of antimicrobial resistance, also known as AMR, calls for research in areas affecting both humans and animals, as resistant bacteria can be transferred from animals to humans in the food chain.
