High Dopamine Transporter Levels Not Correlated with ADHD

11-29-2006 · Brookhaven National Laboratory

Results from a brain-imaging study conducted at the U.S. Department of Energy's Brookhaven National Laboratory in collaboration with Mount Sinai School of Medicine in New York indicate that levels of a brain protein proposed as a diagnostic marker for attention-deficit hyperactivity disorder (ADHD) are not positively correlated with the disease. In fact, the study found lower levels of these "dopamine transporter" proteins in certain brain regions of ADHD patients compared with controls.

ADHD Appears to Be Associated With Depressed Dopamine Activity in the Brain
08-06-2007 · Brookhaven National Laboratory
Adults with attention-deficit/hyperactivity disorder (ADHD) show a blunted response to the drug methylphenidate (Ritalin), which increases brain dopamine levels. This suggests that dopamine dysfunction may be involved with ADHD symptoms and may contribute to substance abuse that often occurs simultaneously.

Gene variant is associated with brain anatomy, clinical course of ADHD
08-06-2007 · EurekAlert!
A variant of the dopamine receptor gene may be associated with attention-deficit/hyperactivity disorder and with thinner tissue in areas of the brain that handle attention, but also appears associated with better clinical outcomes among individuals with the disorder, according to a report in the August issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Workers in no-smoking restaurants show lower carcinogen levels
06-29-2007 · EurekAlert!
A new study compares the level of a tobacco-specific carcinogen in nonsmokers who work in restaurants that allow smoking with that of employees in restaurants that ban it. Restaurant workers exposed to tobacco smoke on the job were more likely to have a detectable level of NNK, a carcinogen implicated in the development of lung cancer, than those who worked in tobacco-free environments.

Enzyme may hold key to new treatment of diabetic kidney disease
11-07-2006 · EurekAlert!
Northwestern University researchers have found an enzyme, called "ACE2," may hold the potential to treat diabetic kidney disease, the most common form of kidney disease.The researchers have found low levels of the ACE2 enzyme in kidneys of diabetic mice. When ACE2 was further decreased with an inhibitor drug, kidney disease worsened. Studies are now needed using compounds that increase the level of ACE2 in the kidneys of diabetic mice to see if it reverses or prevents kidney disease.

PSA doubling predicts prostate cancer recurrence
04-09-2007 · EurekAlert!
A detectable level of prostate-specific antigen (PSA) is the first indicator of recurrent prostate cancer after radical prostatectomy. In a new Mayo Clinic study, the concept of PSA doubling time is found to be a reliable tool to distinguish which patients have prolonged innocuous PSA levels after therapy from those who are at great risk for disease recurrence and death from prostate cancer. Doubling time is defined as the duration for PSA levels in the blood to increase by 100 percent.

Protein may be linked to melanoma recurrence
06-02-2007 · EurekAlert!
Higher levels of a protein called S-100 in melanoma patients may correlate with a higher risk of the disease returning, say researchers at the University of Pittsburgh Cancer Institute. The study tested serum samples from 103 patients treated with high-dose interferon an average of eight years prior. When the researchers examined levels of S-100 in the samples, they found that the higher the level of the protein, the greater likelihood the disease had returned.

Moderate prenatal exposure to alcohol and stress in monkeys can cause touch sensitivity
02-07-2008 · EurekAlert!
A new study that exposed monkeys to moderate levels of alcohol and stress in pregnancy found increased sensitivity to touch in the monkeys' babies. Using a brain neuro-imaging technique, the researchers found that sensitivities to touch were related to changes in the brain chemical dopamine one area of the brain. Since sensitivity to touch in human children can lead to behavioral and emotional problems, this research has important implications for preventing childhood disorders.

Benefits of more homework vary across nations, grades
02-27-2007 · EurekAlert!
A study of global homework patterns suggests that the benefits of more homework assignments to boost student test scores may vary widely according to the grade level, the quality of a nation's schools and the perceived value of homework. Therefore, researchers caution that government and education policymakers need to consider the appropriate grade levels and related impact before trying to create overall homework policies for schools.

Cutting salt does not reduce processed food safety say scientists
09-03-2007 · EurekAlert!
Low salt foods are just as safe or safer than high salt level products in spite of expectations that cutting salt levels in food would increase the risk of spoilage by bacteria, say scientists today, Sept. 4, 2007, at the Society for General Microbiology's 161st Meeting at the University of Edinburgh, UK, which runs Sept. 3-6, 2007.

New study: Pine bark extract reduces ADHD symptoms in children
09-12-2007 · EurekAlert!
Attention deficit hyperactivity disorder is a prevailing issue in the United States, with millions of children getting diagnosed every year. A new study reveals that Pycnogenol, an antioxidant plant extract from the bark of the French maritime pine tree, reduces ADHD in children. The study shows Pycnogenol balances stress hormones, which lowers adrenaline and dopamine, resulting in a decrease of ADHD.
