Neuron death in ALS more complex than previously thought

Brown University researchers have uncovered new clues about the progression of Amyotrophic Lateral Sclerosis (ALS), a surprisingly common disease that causes the death of motor neurons that control voluntary muscles such as those involved in walking, talking, chewing or breathing. A team led by Anne Hart, a professor of neuroscience at Brown, discovered that two

Diet affects the breast microbiome in mammals

Diet influences the composition of microbial populations in the mammary glands of nonhuman primates, researchers report October 2 in the journal Cell Reports. Specifically, a Mediterranean diet increased the abundance of probiotic bacteria previously shown to inhibit tumor growth in animals. “We showed for the first time that breast-specific microbiome populations are significantly affected by

High-risk HPV linked to improved survival in cervical cancer

The presence of the human high-risk papillomavirus (hrHPV) in the diagnosis of invasive cervical cancer is linked to a greatly improved prognosis compared to cases in which hrHPV cannot be identified in the tumour, according to researchers at Karolinska Institutet in Sweden, who have published their results in the scientific journal PLOS Medicine. The researchers

Alternative medicines may aid in the treatment of psoriasis

(HealthDay)—Some complementary and alternative medicines (CAMs) may be helpful in the treatment of psoriasis, according to a review published online Sept. 5 in JAMA Dermatology. A. Caresse Gamret, from the University of Miami, and colleagues conducted a systematic literature review to identify studies evaluating all documented CAM psoriasis interventions. Included interventions had more than one

Compound improves social interaction in autism mouse model

Children with autism often find social interactions awkward, leaving them isolated. Now in a study appearing in ACS’ Journal of Medicinal Chemistry, scientists report that they have discovered a first-of-its-kind compound that promotes social interaction among laboratory mice that display autistic traits. The finding could lead to the development of drugs capable of improving social

New developments in EEG brain scans could help spot mental disorders early

Patients suffering from mental and neurological disorders, including autism, ADHD and dementia, could benefit from new developments in brain scanning technology, according to a new study published in The Neurodiagnostic Journal. Recent advances in electroencephalography (EEG) technology, which may one day be used to measure brain function throughout a patient’s lifespan, could encourage earlier diagnoses

Does our environment affect the genes in our brains?

Is there a link between differences in IQ test performance and the activity of certain genes? Researchers from Charité – Universitätsmedizin Berlin have shown that modifications in the structure of a specific gene have a negative impact on individual test performance. This suggests that environmentally induced epigenetic changes to our genetic material have a greater

WHO warns of ‘perfect storm’ for Ebola in eastern Congo

The emergencies chief for the World Health Organization says insecurity, public defiance about vaccinations and political jockeying could create a “perfect storm” leading Congo’s latest Ebola outbreak to spread. Dr. Peter Salama says the response is at a “critical juncture” in eastern North Kivu province, where the outbreak was declared nearly two months ago. Health
