London: A new study by researchers said, eating an egg a day and having a high-cholesterol diet habit will not increase heart attack risk. It will not affect people inclined even genetically.

 

Relatively higher intake of dietary cholesterol, or eating an egg every day, are not associated with an elevated risk of incident coronary heart disease or with the thickening of the common carotid artery walls, the study said.

Frequent consumption of eggs does not increase the risk of cardiovascular diseases even in persons who are genetically predisposed to a greater effect of dietary cholesterol on serum cholesterol levels, the research showed.

Furthermore, no association was found among those with the APOE4 phenotype, which affects cholesterol metabolism, the findings, published in the American Journal of Clinical Nutrition, revealed.

The dietary habits of 1,032 men aged between 42 and 60 years and with no baseline diagnosis of a cardiovascular disease were assessed at the onset the Kuopio Ischaemic Heart Disease Risk Factor Study, KIHD, in 1984-1989 at the University of Eastern Finland.

During a follow-up of 21 years, 230 men had a heart attack, and 32.5 percent of the study participants were carriers of APOE4.

In the highest control group, the study participants had an average daily dietary cholesterol intake of 520 mg and they consumed an average of one egg per day.(IANS)

Researchers Unveil the Power of Turmeric in Fighting Cancer

Curcumin is also known to exhibit anti-cancer properties, but its poor solubility in water had impeded curcumin's clinical application in cancer

A team of Indian-American researchers at the University of Illinois at Urbana-Champaign (UIUC) and at the University of Utah at Salt Lake City, has used an ingenious process to enable curcumin to kill cancer cells.

Curcumin is the active ingredient of turmeric (haldi), the ubiquitous kitchen spice that gives curry its yellow color. Turmeric has been used in India for thousands of years as a spice and medicinal herb because of its powerful anti-inflammatory and strong antioxidant property.

Curcumin is also known to exhibit anti-cancer properties, but its poor solubility in water had impeded curcumin’s clinical application in cancer. A drug needs to be soluble in water as otherwise it will not flow through the bloodstream.

Despite decades of research, the development of efficient strategies that can effectively deliver poorly water-soluble curcumin to cancer cells had remained a challenge.

A team headed by Dipanjan Pan, associate professor of bioengineering at UIUC, has now found a way out.

“Curcumin’s medicinal benefit can be fully appreciated if its solubility issue is resolved,” Pan told this correspondent in an e-mail.

Pan’s laboratory collaborated with Peter Stang at the University of Utah on ways to be able to render curcumin soluble, deliver it to infected tumors and kill the cancer cells.

Because platinum is a commonly used cancer therapeutic agent in the clinic, the researchers decided to experiment with a drug consisting of a combination of platinum and curcumin.

“It is a combination of clever chemistry and nano-precipitation utilising host guest chemistry,” Pan explained. “The sophisticated chemistry leads to self-assembled hierarchical structure that drives the solubility of curcumin and simultaneously delivers an additional anticancer agent, i.e. platinum. The combined therapeutic effect — of curcumin and platinum — is lethal for the cancer cells.”

The team has reported its work in the “Proceedings of the National Academy of Sciences” in the US.

According to their report, the metallocyclic complex created using platinum “not only enabled curcumin’s solubility, but proved to be 100 times more effective in treating various cancer types such as melanoma and breast cancer cells than using curcumin and platinum agents separately”.

“Our results demonstrate that curcumin works completely in sync with platinum and exerts synergistic effect to show remarkable anticancer properties,” says the report. “The platinum-curcumin combination kills the cells by fragmenting its DNA.”

“Extensive animal studies are in progress in my laboratory, including in rodents and pigs,” Pan said. His team also hopes to prove that this method will be effective in killing cancer stem cells — the birth place of cancer cells — thereby preventing the recurrence of cancer.

Pan’s team included post-doctoral researcher Santosh Misra at UIUC, and Sougata Datta, Manik Lal Saha, Nabajit Lahiri, Janis Louie, and Peter J. Stang from the University of Utah. (IANS)
