Researchers create gene circuit that permits precise tuning of a gene's expression in a cell

Researchers have crafted a gene circuit that permits precise tuning of a gene's expression in a cell, an advance that should allow for more accurate analysis of the gene's role in normal and abnormal cellular function.

Small molecules block cancer gene

Finding molecules that block the activity of the oncogene Stat 3 (signal transducer and activator of transcription) required screening literally millions of compounds, using computers that compared the structure of the cancer-causing gene to those of the small molecules, said a Baylor College of Medicine researcher in a report that appears in the current online issue of the journal PLoS One (Public Library of Science ONE).

'Seeing' stem cells helps in fight against peripheral arterial disease

Interventional radiologists are fitting together the puzzle pieces of how to use stem cells to create new or more blood vessels to treat peripheral arterial disease (PAD) in those individuals with extensively narrowed or clogged arteries.

Discovery of new mechanism the malaria parasite uses to enter human red blood cells

Virginia Commonwealth University Life Sciences researchers have discovered a new mechanism the malaria parasite uses to enter human red blood cells, which could lead to the development of a vaccine cocktail to fight the mosquito-borne disease.

Saving limbs with drug-eluting stents

Attempts to treat critical limb ischemia in peripheral arterial disease (PAD) patients with below-the-knee angioplasty are still thwarted by restenosis (the re-narrowing of the artery at the site of angioplasty or stenting), the need for repeat treatments and the continued progression of atherosclerotic disease, leading to tissue death (gangrene) and amputation.

First 'nano' treatments to target cancer cells

Cancer Research UK scientists have for the first time developed a treatment that transports 'tumour busting' genes selectively to cancer cells, according to a study published online in Cancer Research.

Study links inflammation and calcium signaling in heart attack

A new study led by University of Iowa researchers has found an unexpected new link between this inflammation in heart muscle following a heart attack and a previously known enzyme called calcium/calmodulin-dependent protein kinase II or CaM kinase II.

How chemicals present in cranberries prevent urinary tract infections

Chemicals present in cranberries - and not the acidity of cranberry juice, as previously thought - prevent infection-causing bacteria from attaching to the cells that line the urinary tract, as documented in a report published in Journal of Medicinal Food.

New insights on heart's 'fight or flight' response to stress

Even for those without a heart condition, it's a peculiar feeling when your heart "races" in response to stress.

New procedure for eliminating reblockage of arteries

An easily implementable technique to avoid reblockage of arteries that have been cleared through angioplasty and stent insertion has been developed by researchers led by Prof. Boris Rubinsky of the Hebrew University of Jerusalem.

Few physicians support private banking of umbilical cord blood

A survey of physicians has found broad support for the position that parents should not bank their newborns' umbilical cord blood in a private blood bank unless another member of the family is at risk for a blood disease that will require a stem cell transplant.
