  • Do you want to stay fit and longer? Daily push-ups and sit-ups may add a few extra years to your lifespan, reveals new research.

Benefits of doing Strength-based Exercise

The research found that the people who did strength-based exercise had a 23 percent reduction in risk of premature death and a 31 percent reduction in cancer-related death.

“The study shows that strength-based exercise may be just as important for health as aerobic activities like jogging or cycling,” said Emmanuel Stamatakis, Associate Professor at the University of Sydney in Australia.

“And assuming our findings reflect cause and effect relationships, it may be even more vital when it comes to reducing the risk of death from cancer,” Stamatakis added.

The researchers observed 80,306 adults for two years and made some adjustments in order to reduce the influence of certain factors such as age, sex, health status, lifestyle behavior and educational level.

All participants with established cardiovascular disease or cancer at the baseline and those who passed away in the meanwhile were excluded from the study.

The research, published in the American Journal of Epidemiology, showed that exercises performed using one’s own body weight without specific equipment were just as effective as gym-based training.

“When people think of strength-based exercise, they instantly think of doing weights in a gym, but that doesn’t have to be the case,” noted Stamatakis.

“Many people are intimidated by gyms, the costs or the culture they promote, so it’s great to know that anyone can do classic exercises like triceps dips, sit-ups, push-ups or lunges in their own home or local park and potentially reap the same health benefits,” the researcher said. (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)
