Cystic Fibrosis: Engineered Proteins Can 'Bypass' Genetic Defect
Published August 28, 2008, 7:36 am, Science Daily
By manipulating the machinery used by our cells for quality control, researchers have found a way to restore the function of cystic fibrosis (CF) airway cells. This could significantly reduce the sticky mucus that plugs the lungs of CF patients, which leads to antibiotic-resistant infections and untimely death.
Clearing the airways in cystic fibrosis
Published August 28, 2008, 6:40 am, EurekAlert!
( Federation of American Societies for Experimental Biology ) By manipulating the machinery used by our cells for quality control, researchers from the University of Pittsburgh have found a way to restore the function of cystic fibrosis (CF) airway cells. This could significantly reduce the sticky mucus that plugs the lungs of CF patients, which leads to antibiotic-resistant infections and ...

Cells change identity in promising breakthrough
Published August 27, 2008, 10:23 am, The San Luis Obispo Tribune
Talk about an extreme makeover: Scientists have transformed one type of cell into another in living mice, a big step toward the goal of growing replacement tissues to treat a variety of diseases. The cell identity switch turned ordinary pancreas cells into the rarer type that churns out insulin, essential for preventing diabetes. But its implications go beyond diabetes to a host of ...

Viagra Shows New Potential To Prevent Clots
Published August 27, 2008, 6:17 am, Medical News Today
The cellular response to Viagra may be harnessed to help create new anticoagulant therapies, according to an article released on August 26, 2008 in the Proceedings of the National Academy of Sciences (PNAS.) The enzyme PDE5 is known to modulate platelet activity. Normally, platelets exist in the blood and have an integral role in blood clotting.

Amid the hype, several treatments do cut wrinkles
Published August 27, 2008, 12:02 am, The Oregonian
Nostrums that promise to smooth wrinkled skin are a staple of snake-oil salesmen everywhere, but now strong evidence shows that some treatments are effective. During the past decade, researchers have learned which treatments work, and why.

- Enzyme manipulation could give grape-flavored bananas: >>>DA H Probably just a muse but really high tech stuff - vannila flavoured pumpkin?>&g t;>EXTRACT Genetic manipulation of enzymes in plants responsible for aromas in fruit and vegetable may enable fine tuning of flavours, suggests new research in Nature. Researchers from the University of Texas report that manipulation of the hydroperoxide lyase (HPL) enzyme can change the production of green leaf volatiles (GLV) that give characteristic aromas to fruits and vegetables. ?Genetic engineering/mo dification (GM) of green leaf volatile production has important implications for manipulating food flavour," said Professor C.S. Raman, the senior author of the study. "For example, the aroma of virgin olive oil stems from the volatiles synthesized by olives. By modifying the activity of enzymes that generate these substances, it may be possible to alter the flavour of the resulting oils."
