The degree to which neural functioning reflects individual-level behavioural phenotype … Continue Reading Neuroimaging study identifies new biomarker for autism spectrum disorder in boys.
With Parkinson’s disease clinicians have long noted that the presence of tremors, rather than balance and walking problems is the initial or dominant symptom and hypothesize this may even suggest … Continue Reading Human study identifies genetic variation for type and rate of physical decline Parkinson’s disease.
Allergies are characterized by inappropriate inflammatory responses to benign environmental antigens. Primary clinical approaches to allergic disease consist of symptom control or administration of soluble antigens to skew the immune response … Continue Reading Novel nanoparticle acts like Trojan horse to halt asthma in animal model.
Systemic lupus erythematosus (SLE) is a common autoimmune disorder in which the body’s immune system mistakenly attacks healthy tissues, it can affect the skin, joints, kidneys, brain, and other organs. … Continue Reading Study shows how mitochondria drives autoimmune response in lupus.
