Bodybuilding in today’s time has not just become a competitive sport but has become an integral part of the day for many. Keeping one’s body fit has become a critical aspect that has driven people towards bodybuilding. Bodybuilding is not just lifting weights or the number of pushups one can do at once. It is much more than a physical exertion to the body, although a majority of the bodybuilding exercises require the physical body to be in a robust dynamic state. It also involves mental effort and mental conditioning of the body. In such a practice where the entire body is in motion, improving the performance and getting better results can be game-changing.

Mouse study helps explain the paradoxical pro-cancer effects of paclitaxel
COLUMBUS, Ohio – The very same treatment that thwarts breast cancer has a dark side – it can fuel the spread of the disease to the lungs. (more…)
Insights into how cells move through the body could lead to innovative techniques to stop cancer cells from spreading and causing secondary tumours, according to new UCL research.
Scientists discovered that cells can change into an invasive, liquid-like state to readily navigate the narrow channels in our body. This transformation is triggered by chemical signals, which could be blocked in order to stop cancer cells from spreading. (more…)
One-Way Air Flow May Be 270 Million Years Old
Air flows mostly in a one-way loop through the lungs of monitor lizards – a breathing method shared by birds, alligators and presumably dinosaurs, according to a new University of Utah study.
The findings – published online Wednesday, Dec. 11 in the journal Nature – raise the possibility this breathing pattern originated 270 million years ago, about 20 million years earlier than previously believed and 100 million years before the first birds. Why remains a mystery. (more…)
Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen.
But the amount of carbon dioxide that rainforests absorb, or produce, varies hugely with year-to-year variations in the climate.
In a paper published online (Feb 6 2013) by the journal Nature, a team of climate scientists from the University of Exeter, the Met Office-Hadley Centre and the NERC Centre for Ecology & Hydrology, has shown that these variations reveal how vulnerable the rainforest is to climate change. (more…)
EAST LANSING, Mich. — By identifying a key protein that tells certain breast cancer cells when and how to move, researchers at Michigan State University hope to better understand the process by which breast cancer spreads, or metastasizes.
When breast cancer metastasizes, cancer cells break away from a primary tumor and move to other organs in the body, including the lungs, liver and brain. In work published recently in the journal Cancer Research, MSU researchers Kathy Gallo and Jian Chen show a protein called MLK3 (mixed lineage kinase 3) is a critical driver of breast cancer cell migration and invasion.

Many infections, even those caused by antibiotic-sensitive bacteria, resist treatment. This paradox has vexed physicians for decades, and makes some infections impossible to cure.
A key cause of this resistance is that bacteria become starved for nutrients during infection. Starved bacteria resist killing by nearly every type of antibiotic, even ones they have never been exposed to before. (more…)
EAST LANSING, Mich. — Plagued with a defective heart valve that caused fluid accumulation in his lungs, Leo was in need of serious medical help.
His loved ones opted for open-heart surgery. And after a successful operation, Leo is recovering nicely and leading a full life: Chasing balls, chewing toys and barking at friends. (more…)
