Children of smokers have more than five times higher levels of a nicotine toxin

Children who have at least one parent who smokes have 5.5 times higher levels of cotinine, a byproduct of nicotine, in their urine, according to a study by researchers from Warwick Medical School at the the University of Warwick, and the University of Leicester, published online ahead of print in Archives of Disease in Childhood. more  

Medical metal detector finds 'lost' orthopedic screws

Inspired by the device used to find lost coins in the sand, Johns Hopkins undergraduates have invented a small handheld metal detector to help doctors locate hidden orthopedic screws that need to be removed from patients' bodies. The device emits a tone that rises in pitch as the surgeon moves closer to the metal screw. It also serves as a surgical tool to guide the removal of the hardware. more

Does stimulant treatment for adhd increase risk of drug abuse?

Parents, doctors, and others have wondered whether common treatments for attention-deficit hyperactivity disorder (ADHD) inadvertently predispose adolescents to future drug abuse. The answer may depend on the age at which treatment is started and how long it lasts, say the authors of a new brain-imaging and behavioral study conducted in animals at the U.S. Department of Energy's Brookhaven National Laboratory. The results appear in the June 5, 2007 online issue of the journal Pharmacology, Biochemistry and Behavior. more

A possible mechanistic link between stress and the development of Alzheimer tangles  

Subjecting mice to repeated emotional stress, the kind we experience in everyday life, may contribute to the accumulation of neurofibrillary tangles, one of the hallmarks of Alzheimer’s disease, report researchers at the Salk Institute for Biological Studies. While aging is still the greatest risk factor for Alzheimer’s disease, a number of studies have pointed to stress as a contributing factor. more

Premature vascular and bone changes occur in COPD patients 

Researchers in the United Kingdom have found that patients with COPD, or chronic obstructive pulmonary disease, have greater arterial stiffness. The researchers also found that those COPD patients with osteoporosis, a common complication of the respiratory disease, had even greater arterial stiffness. These premature signs of aging may explain why COPD patients are at greater risk for cardiovascular disease. more

Colon cancer proteins show promise for blood test

Searching for less invasive screening tests for cancer, Johns Hopkins scientists have discovered proteins present in blood that accurately identify colon cancer and precancerous polyps. more
