Increased air pollution could reduce health benefits of living in walkable neighborhoods

Tue, 06/25/2019 - 18:10
The benefits of living in a walkable neighborhood could be diminished by increased exposure to traffic-related air pollution, suggests a study led by St. Michael's Hospital and ICES, a non-profit research institute that uses population-based health information to produce knowledge on a broad range of health care issues.

Exercise effectively protects against subarachnoid hemorrhage

Tue, 06/25/2019 - 18:01
A Finnish study demonstrates that as little as half an hour of light exercise per week effectively protects against subarachnoid hemorrhage, the most lethal disorder of the cerebral circulation.

Exposure to chemical weapons results in lifelong physical and mental ill-health

Tue, 06/25/2019 - 17:52
People exposed to chemical warfare agents often incur chronic damage to their lungs, skin and eyes, for example. They also frequently succumb to depression, anxiety and suicidal thoughts. This is shown by research on survivors from the 1988 gas attacks against Kurdish Halabja in Iraq.

Study uncovers new hunger pathway in the brain

Tue, 06/25/2019 - 17:05
A newly identified hunger pathway in the brain can quickly modify food intake in the presence of food, according to a study of mice published in JNeurosci.

Researchers explore new immune checkpoint for head and neck cancer

Tue, 06/25/2019 - 13:41
A checkpoint may delay travelers but it can help give cancer free rein by suppressing the natural immune response that should destroy it, researchers say.

Sex plays major role in Alzheimer's disease risk

Tue, 06/25/2019 - 13:36
The strongest genetic risk factor for Alzheimer's disease is the apolipoprotein E type 4 allele (ApoE ε4). Research presented by Manish Paranjpe at the 2019 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging used positron emission tomography to show that women who are ApoE ε4 carriers and already experiencing mild cognitive impairment are more susceptible than men to tau accumulation in the brain.

Cholesterol-lowering drugs could increase risk of developing diabetes

Tue, 06/25/2019 - 13:31
A study of thousands of patients' health records found that those who were prescribed cholesterol-lowering statins had at least double the risk of developing type 2 diabetes.

Living environment, air pollution may be linked to increased risk of hypertension

Tue, 06/25/2019 - 13:23
A new study soon to appear in the Journal of Public Health suggests that air pollution and living in apartment buildings may be associated with an increased risk for dangerous conditions like heart disease, stroke, and type 2 diabetes.

Injectable hydrogel offers double punch against bone infections

Tue, 06/25/2019 - 13:14
Surgery prompted by automobile accidents, combat wounds, cancer treatment and other conditions can lead to bone infections that are difficult to treat and can delay healing until they are resolved.

Women more likely to suffer from long-term cognitive impairment after brain tumor radiation

Tue, 06/25/2019 - 12:52
Young women who undergo radiation therapy to treat a pediatric brain tumor are more likely to suffer from long-term cognitive impairment than male survivors, according to a study by Georgia State University researchers.

Researchers identify missing link between amyloid plaques and tau tangles in Alzheimer's

Tue, 06/25/2019 - 12:35
Years before symptoms of Alzheimer's disease appear, two kinds of damaging proteins silently collect in the brain: amyloid beta and tau. Clumps of amyloid accumulate first, but tau is particularly noxious.

Research project aims to develop 'personalized health' approach to prevent antimicrobial resistance

Tue, 06/25/2019 - 12:26
The University of Liverpool and the Liverpool School of Tropical Medicine have been awarded £3.54m for a research project that aims to develop a 'personalized health' approach to prevent and treat antimicrobial resistance.

Food allergy caused by absence of beneficial bacteria in the gut

Tue, 06/25/2019 - 12:08
A study by scientists at Boston Children's Hospital and Brigham and Women's Hospital, published today in Nature Medicine, makes a strong case that the national epidemic of food allergy is caused by the absence of certain beneficial bacteria in the human gut.

Researchers examine strains between bone and graft from animal models

Tue, 06/25/2019 - 11:49
For the first time, scientists have been able to study how well synthetic bone grafts stand up to the rigors and 'strains' of life, and how quickly they help bone re-grow and repair.

PET/CT can aid in earlier diagnosis and treatment assessment of tuberculosis

Tue, 06/25/2019 - 11:45
Research presented at the Society of Nuclear Medicine and Molecular Imaging's 2019 Annual Meeting shows that molecular imaging with 18F-FDG positron emission tomography/computed tomography can evaluate tuberculosis at the molecular level, effectively identifying diseased areas and guiding treatment for patients.

Long-term cryopreservation of semen does not affect future clinical outcomes

Tue, 06/25/2019 - 11:35
Despite a time limit imposed in many countries on the freeze-storage of sperm, a new study from China has found that the long-term cryopreservation of semen in a sperm bank does not affect future clinical outcomes

Researchers find new physical evidence in the brain for types of schizophrenia

Tue, 06/25/2019 - 11:34
In a study using brain tissue from deceased human donors, Johns Hopkins Medicine researchers say they found new evidence that schizophrenia can be marked by the buildup of abnormal proteins similar to those found in the brains of people with such neurodegenerative disorders as Alzheimer's or Huntington's diseases.

PET/CT imaging spots cardiovascular disease risk factors in OSA patients

Tue, 06/25/2019 - 11:29
Research presented at the Society of Nuclear Medicine and Molecular Imaging's 2019 Annual Meeting draws a strong link between severe obstructive sleep apnea and impaired coronary flow reserve, which is an early sign of the heart disease atherosclerosis.

New promising approach repairs system of blood vessels following stroke

Tue, 06/25/2019 - 11:07
Following a stroke, antibodies that inhibit the signaling molecule Nogo-A can help repair blood vessels in the affected brain regions.

Loss of body fat causes growth of the intestine

Tue, 06/25/2019 - 10:56
Teagasc research shows that loss of body fat causes the growth of the intestine and increases its capacity to absorb nutrients. This presents new approaches for weight management.
