NUS researchers found that regular consumption of tea brewed from tea leaves reduces elderly persons’ risk of cognitive decline

Tea drinking reduces the risk of cognitive impairment in older persons by 50% and as much as 86% for those who are genetically at risk of Alzheimer’s. A cup of tea a day can keep dementia away, and this is especially so for those who are genetically predisposed to the debilitating disease, according to a recent study led by Assistant Professor Feng Lei from the Department of Psychological Medicine at National University of Singapore’s (NUS) Yong Loo Lin School of Medicine.

The longitudinal study involving 957 Chinese seniors aged 55 years or older has found that regular consumption of tea lowers the risk of cognitive decline in the elderly by 50 per cent, while ...

Eosinophils stimulate β3 adrenoreceptors through the release of soluble factors.

Immune cells which are reduced in number by obesity could be a new target to treat diseases such as type 2 diabetes and hypertension that affect overweight people, according to a collaborative study between The University of Manchester, Lund University and the University of Salford. In a study published in the journal Scientific Reports, reseachers investigated eosinophils. Eosinophils are present in perivascular adipose tissue (PVAT), which surrounds blood vessels and helps to maintain normal blood vessel function by reducing artery contraction.

The current research found that eosinophils were considerably reduced in the PVAT in obesity in mice, and that the PVAT function was severely impaired, contributing ...

Folinic acid

People with certain forms of early-onset Parkinson’s disease could potentially benefit from taking a medication used to treat certain forms of cancer, according to new research by University of Leicester scientists and funded by the Medical Research Council. The study suggests that folinic acid, used in medications to treat bowel cancer, can also protect neurons associated with Parkinson’s disease in fruit flies.

Dr Miguel Martins, MRC Toxicology Unit at the University of Leicester explained: “Parkinson’s disease is a disabling disorder for which no cure is yet available; further, after dopaminergic neurons are lost, only a few palliative treatment options for Parkinson’s symptoms are available...

Scientists have developed a new, highly accurate method that analyzes metabolic biomarkers to assess whether a child is on the autism spectrum Autism spectrum disorder affects about 1.5% of all children, but its exact cause remains unknown, and diagnosis requires a multidisciplinary team of doctors. Previous research has revealed certain differences in metabolic processes between children on the autism spectrum and neurotypical children...
