University of Leicester-led study finds way to reverse symptoms of Parkinson’s and Alzheimer’s

A five-year study by an international team led from the University of Leicester has found a way of ‘reversing’ symptoms of neurodegenerative diseases such as Parkinson’s and Alzheimer’s – using fruit flies as test subjects.

New blood treatment technology could reduce malaria risk following blood transfusions

Patients, especially children, who undergo blood transfusions in sub-Saharan Africa are at high risk of transfusion-transmitted malaria. A new trial, published in The Lancet today, suggests that treating donated blood with a new technology that combines UV radiation and vitamin B is safe and could minimise the risk of malaria infection following blood transfusions.

ADHD highly prevalent among children with vision problems

Children with vision problems not correctable with glasses or contact lenses may be twice as likely to have a diagnosis of attention deficit/hyperactivity disorder (ADHD), suggests a study in the May issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

Researchers reveal how bile component taurine attracts Vibrio cholera

A group of researchers from Osaka University, Hosei University, and Nagoya University have revealed the molecular mechanism that Vibrio cholerae, the etiological agent of cholera, is attracted by bile. This group has also successfully detected the ligand binding to the bacteria chemoreceptor in vivo for the first time. These results may significantly advance research on mechanism and control of V. cholerae.

Single season of contact sports can cause measurable brain changes

Repeated impacts to the heads of high school football players cause measurable changes in their brains, even when no concussion occurs, according to research from UT Southwestern Medical Center's Peter O'Donnell Jr. Brain Institute and Wake Forest University School of Medicine.

Hearing aid use improves cognitive function in hearing-impaired older adults

A study conducted by researchers at Columbia University Medical Center found that older adults who used a hearing aid performed significantly better on cognitive tests than those who did not use a hearing aid, despite having poorer hearing. The study was published online in the American Journal of Geriatric Psychiatry.

Researchers find strong possibility of preventing, curing neurological conditions using gut bacteria

Could bacteria in your gut be used to cure or prevent neurological conditions such as post-traumatic stress disorder (PTSD), anxiety or even depression? Two researchers sponsored by the Office of Naval Research (ONR) think that's a strong possibility.

Same genetic changes responsible for gastrointestinal problems in children with autism

Researchers at Columbia University Medical Center have found evidence in mice that, for some types of autism, gastrointestinal difficulties may originate from the same genetic changes that lead to the behavioral and social characteristics of the condition. The study was published in the Journal of Clinical Investigation.

Criminology theory to combat counterfeit, sub-standard medicines

Around the world, especially in developing nations, counterfeit medicines are a real problem. Until now, in many countries there hasn't been a standard protocol to conduct investigations and pursue prosecution.

Children living closer to major roadways have increased risk of lower lung function, study finds

According to new research led by Beth Israel Deaconess Medical Center pulmonologist and critical care physician Mary B. Rice, MD, MPH, improved air quality in U.S. cities since the 1990s may not be enough to ensure normal lung function in children. The findings were recently published in the American Journal of Respiratory and Critical Care, a journal of the American Thoracic Society.

Exposure to blue light may lead to eyestrain but does not damage retina

Nearly 90 percent of adults use digital devices for two or more hours per day, according to The Vision Council's 2016 Digital Eye Strain Report, exposing consumers to blue light that some suggest is dangerous.

New study finds no increase in food-specific IgE levels linked to food allergies

A new study using 5,000 stored blood samples found no increase in the presence of food-specific immunoglobulin E (IgE) — a blood marker associated with food allergy — in children's blood between the 1980s and the 2000s.

Hydrocortisone drug can also prevent lung damage in premature babies

Research from Ann & Robert H. Lurie Children's Hospital of Chicago conducted in mice shows the drug hydrocortisone -- a steroid commonly used to treat a variety of inflammatory and allergic conditions -- can also prevent lung damage that often develops in premature babies treated with oxygen.

Study shows canine AD shares significant features of human version

Atopic dermatitis (AD), a chronic inflammatory skin condition and the most common form of eczema, is estimated to afflict as much as 10 percent of the U.S. population, and is much more common now than it was 50 years ago. Veterinary clinical estimates also show that approximately 10 percent of dogs have atopic dermatitis.

Transforming MR images into body composition measurements: an interview with Olof Leinhard

Today's medical science utilizes relatively simple anthropometric measures that describe the body, such as body mass index (BMI) and waist circumference. All of these measures are approximations of the body with the intention to characterize what's inside reflecting underlying phenomena that underpin the risk for different diseases.

Study sheds light on mechanism of empty memories in epileptic patients

Between seizures and continually, brain cells in epileptic patients send signals that make "empty memories," perhaps explaining the learning problems faced by up to 40 percent of patients. This is the finding of a study in rats and humans led by researchers at NYU Langone Medical Center and published April 25 in Nature Medicine.

Changes in chromatin structure may promote cancer

Cancer development is a complex process involving both genetic and epigenetic changes. Genetic changes in oncogenes and tumor-suppressor genes are generally considered as primary causes, since these genes may directly regulate cellular growth. In addition, it has been found that changes in epigenetic factors, through mutation or altered gene expression, may contribute to cancer development.

Brain chemical dopamine plays key role in representing or encoding movement

Princeton University researchers have found that dopamine - a brain chemical involved in learning, motivation and many other functions - also has a direct role in representing or encoding movement. The finding could help researchers better understand dopamine's role in movement-related disorders such as Parkinson's disease.

Borrelia infection can cause scleratrophic skin lesions in certain countries

This review summarizes the literature on scleratrophic skin lesions as a manifestation of a Borrelia infection. An association of morphea with Lyme borreliosis LB was mainly reported from Middle-European Countries, Japan and South America. B. afzelii has been identified predominantly from the chronic skin lesions of acrodermatitis chronica atrophicans (ACA) and has been cultivated from morphea lesions in isolated cases.
