Study Suggests Vitamin K Deficiency as an Osteoporosis Risk Factor

...fully functional. This protein is part of the bone structure when it is "carboxylated" (a chemical modification of the protein that changes its shape making it easy to bind to calcium) in the presence of sufficient vitamin K. With adequate vitamin K, this protein can bind to calcium in the bone environment---s...

"The polymers that Kathryn Uhrich and her team have pioneered and developed are unique in that they can serve as barriers while also repre...

Aussie Doctors Claim Breakthrough in Breast Cancer Treatment

...nventional computed tomography (CT) scans show the structure of the body. He said, "We can now offer patients other treatments and say this current treatment is not working." According to Professor Rod Hicks, chairman of molecular imaging at the centre the use of PET scans to monitor the success of treatmen...

Escalating Healthcare charges in UAE

... to the government’s implementation of the new fee structure in 2003, said “since the government increased the fees for its healthcare sector, the private healthcare businesses hiked their costs by about 150 per cent”. “Healthcare in the UAE has definitely become a ‘lucrative’ business since healthcare costs...

Weird Protein Puzzles Researchers

...l thinking that relied on the information that the structure of a protein is fixed by the DNA template, but now researchers feel that a bit of rearrangement does happen after the protein has been created. Researchers say that the peptide sequence differs in comparison with the template sequence of DNA, in c...

... more than just faces. "We've looked at the fine structure of face-selective regions in the brain, and it argues against prevailing theories," said first author Kalanit Grill-Spector, PhD, assistant professor of psychology and a researcher in the Neuroscience Institute at Stanford. Using high-resolution fu...

Processed foods – "the" cause of obesity!

...like sugar and is used as a sugar, its biochemical structure is different from sugar, which prevents it from being metabolized or broken down as a sugar," he explains. Lustig sums up on how these biochemical disorders are the root causes of obesity: "The higher your insulin, the more your brain thinks you're ...
