One-third of adults with diabetes still don't know they have it

... symptoms, is serious because many people with the condition develop type 2 diabetes in the next 10 years. Also, pre-diabetes substantially raises the risk of a heart attack or stroke even if type 2 diabetes does not develop. People with pre-diabetes may have IFG or impaired glucose tolerance (IGT) or both....

Study reveals how ADHD drugs work in brain

... public anxiety over the treatment of a behavioral condition with pharmacological drugs, doctors have continued to prescribe meds like Adderall, Ritalin and Dexedrine because - quite simply - they work better than anything else. ADHD drugs fall into a class of medications known as stimulants. ADHD stimulants...

MIT sheds light on how tumor cells form

...have fewer or more than 23 pairs of chromosomes, a condition called aneuploidy. To date it has not been clear how tumor cells become aneuploid. "Checkpoint proteins" within cells work to prevent cells from dividing with an abnormal number of chromosomes, but scientists have been puzzled by evidence that an...

Five surprising facts about starvation that could change the international agenda

UF scientists restore sight to chickens with blinding disease

... from producing an enzyme essential for sight. The condition closely models a genetic disease in humans that causes Leber congenital amaurosis type 1, or LCA1. About 2,000 people in the United States are blind because they have a disease that falls in the LCA family. "Enabling chickens that can't see to peck ...

Chromosomal abnormalities in sperm higher after vasectomy reversal

... been studying men with obstructive azoospermia, a condition where sperm are created but cannot be mixed with the ejaculatory fluid due to a physical obstruction (such as a vasectomy). He found that they had high rates of chromosomal aneuploidy (where an abnormal number of specific chromosomes or chromosome ...

Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...ght be able to get an analysis of someone's health condition in 15 minutes rather than having it take two days," says Picraux. Digital magnetofluidics will allow for more compact and portable testing instruments that will work fast and require less power to operate, he says. It also holds promise for impro...

'Signature' of chromosome instability predicts cancer outcomes

...to develop. Chromosomal instability leads to a condition known as aneuploidy, in which chunks of DNA are either missing or duplicated. The technique developed by Szallasi's team indirectly measures the degree of aneuploidy -- and thus the degree of chromosomal instability -- by looking for abnormal express...

Survivors of childhood polio do well decades later as they age

...ers have suggested that polio is a more aggressive condition later in life, but we've actually found it to be relatively benign," says Eric Sorenson, M.D., Mayo Clinic neurologist and lead study researcher. "Our results suggest that polio survivors may not age any differently than those in the normal populatio...

Research reveals inner workings of immune system 'thermostat'

...ly defective tyk2 gene were immune to arthritis, a condition caused by inflammation. But these mutants were much more susceptible to opportunistic infections. Why? Without tyk2, Yap found, mice didn't make enough of the pro-inflammatory warriors that destroy harmful bugs and cause inflammation. This finding es...

Tiny airborne particles are a major cause of climate change

... combination prevents atmospheric instability ?the condition needed to form clouds and rain. A stable atmosphere means fewer clouds; fewer clouds mean less reflection of sunlight; less reflection of sunlight and absorption of radiation lead to warming. Policy makers have argued that, in the bottom line, the ...

Light guides flight of migratory birds

...ferences could be recorded; songbirds in migratory condition leave tracks or scratches on the sides of the funnel as they attempt to take flight in the migratory direction. A problem arises, however, because funnels block the lower 20 degrees of the sky. In the only two experiments (out of 30 or so) carried ou...

A new look at the state of the oceans

Bedsores and bald hides: Novel roles revealed for a 'scaffolding' protein

...n, which results in a thin coat of fragile hair, a condition resembling alopecia or thinning, balding hair. That the hair is fragile is not surprising given that K17 is a keratin protein, known to provide structure and strength, says Coulombe. Hair follicle cells cycle continuously through three phases - grow...

Further studies by the team will examine whether SIVs carrying Nef genes artificially made incapable of limiting T cell activation might become more pathogenic in their natural monkey hos...

Hibernating myocardium is a condition in which heart cells that have experienced reduced blood flow over an extended period of time due to narrowed coronary arteries adapt to this deprivation by down-regulating metabolism while remaining functionally viable.
