Evidence is mounting to link toxoplasmosis with schizophrenia

Keep pet cats inside, stop feeding strays, cook meat sufficiently and reconsider the way the veterinary profession and public health agencies think - and teach - about the zoonotic pathogen Toxoplasma gondii.

Aβ and Fyn cooperate to cause Alzheimer-like changes in the brain

Reporting in two companion papers in the October 19 issue of the Journal of Neuroscience, investigators from the Gladstone Institute of Neurological Disease show in genetically engineered mouse models of the disease that the accumulation of Alzheimer-related neurotoxic amyloid-beta (Aâ) peptides can deplete key proteins in a specific memory center of the brain.

Cutting-edge research to develop this range of next-generation biomedical devices

Revolutionary new self-diagnostic devices to provide early warning of deadly and debilitating illnesses like cancer, diabetes and heart disease are the aim of a Euro 22.5m Science Foundation Ireland research facility to be established at Dublin City University.

New prostate cancer test far more accurate

At present in order to predict prostate cancer outcomes, doctors rely on measures that suggest how far the tumour has spread and how abnormal the cancer cells appear under the microscope.

Cannabis smoke less likely to cause cancer than tobacco smoke

According to a leading U.S. expert, cannabis smoke is less likely to cause cancer than tobacco smoke.

Brain injury can cause detrimental functional changes in brain regions far from the site of the actual injury

A study of patients who have difficulty paying attention to the left side of their environment has provided some of the first direct evidence that brain injury can cause detrimental functional changes in brain regions far from the site of the actual injury.

Discovery could lead to tests for the clinic or battlefield to diagnose ailments with just a few drops of blood

A way to detect fragments of broken brain cells that leak into the bloodstream may help doctors more quickly and precisely treat people with severe head injuries or brain diseases, say researchers at the University of Florida's McKnight Brain Institute.

New genetic discovery may help explain why some people develop high blood pressure and others don't

It also gives new insight into how the kidneys govern the balance of salt in the body, a crucial task for regulating blood pressure. And, it reveals how a gene already linked to behavior and mental health can play a role in the body, as well as the brain.

Significant step forward in the genome era

In what promises to be a significant step forward in the genome era, the National Human Genome Research Institute (NHGRI) today announced plans to devote a portion of its large-scale sequencing capacity to efforts aimed at identifying the genetic roots of specific diseases that have long eluded gene hunters.

Rett syndrome discovery

The gene responsible for Rett syndrome, a devastating neurological disease found mostly in girls, not only silences some genes but in combination with another also regulates alternative splicing, crucial to the formation of proteins -- a finding that may explain the symptoms associated with this puzzling disorder and others related to it

Tourette syndrome linked to SLITRK1 gene

Tourette syndrome is a distressing condition which affects one in every 100 people.

Ethnic differences in cardiovascular risk factors

Heredity plays a major role in determining the blood lipid profile and heart rate variability of blacks and whites, two major risk factors for coronary artery disease, researchers say.

Combining alcoholics anonymous and treatment works best

Most clinical studies examine individuals either during or immediately following treatment. A study in the October issue of Alcoholism: Clinical & Experimental Research tracks individuals for 16 years who have first acknowledged their alcohol-use problems and then chosen Alcoholics Anonymous (AA), treatment, or both.

Cancer survivors have unique and long-term cancer-specific side effects.

Patients surviving childhood Hodgkin disease suffer strokes later in life at rates about four times that of the general population, UT Southwestern Medical Center researchers have found.

Moderate drinking has effects on blood coagulation, primarily as a "blood thinner"

Population studies have shown that moderate drinkers tend to have lower rates of heart disease but higher rates of bleeding-type strokes than abstainers. A potential mediator of these two contrasting effects of alcohol may be platelet function.

Biologists uncover pivotal role of a gene called "Cut"

A DNA-binding protein, Cut interprets and transcribes the developmental signals sent through the "Notch" gene, which regulates a layer of epithelial cells as they replicate and divide. But when Cut garbles those signals the result is uncontrolled cell proliferation, sometimes with dire genetic and health consequences.

Long-term smoking linked to diminished mental proficiency

The association between long-term smoking and diminished mental proficiency in 172 alcoholic and non-alcoholic men was a surprising finding from a study that set out to examine alcoholism's long-term effect on the brain and thinking skills.

Obesity associated with a threefold increase in SCD1 expression in obese muscle

The gene encoding an enzyme that hinders muscle from burning fat manufactures three times more enzyme in the muscle of obese people than lean people, researchers from Duke University Medical Center and Louisiana State University have found. This causes the obese muscle tissue to both store more fat and burn less fat, the researchers said.

Obesity linked to dementia and Alzheimer's disease

Individuals who were obese at midlife had an increased risk for dementia later in life compared to individuals of normal weight, according to an article in the October issue of Archives of Neurology.

New way to measure the impact of AIDS on the living brain

A new University of California - Los Angeles/University of Pittsburgh imaging study for the first time shows the selective pattern of destruction inflicted by AIDS on brain regions that control motor, language and sensory functions. High-resolution 3-D color scans created from magnetic resonance images (MRI) vividly illustrate the damage.
