How the eyes might be windows to the risk of Alzheimer’s disease: Researchers say how quickly a person’s pupil dilates while taking cognitive tests

Alzheimer’s disease (AD) begins to alter and damage the brain years — even decades — before symptoms appear, making early identification of AD risk paramount to slowing its progression. In a new study published online in the September 9, 2019 issue of the Neurobiology of Aging, scientists at University of California San Diego School of […]

Vegetable-rich diet lowers fatigue in multiple sclerosis patients by raising good cholesterol: Fatigue affects majority of MS patients, impacting quality of life and ability to work full time

Higher levels of blood high-density lipoprotein (HDL) — or good cholesterol — may improve fatigue in multiple sclerosis patients, according to a new University at Buffalo-led study. The pilot study, which investigated the effects of fat levels in blood on fatigue caused by multiple sclerosis, found that lowering total cholesterol also reduced exhaustion. The results, […]

Voluntary control of brainwaves in deep brain of patients with Parkinson’s disease

Parkinson’s disease is associated with abnormal beta wave activity in the subthalamic nucleus (STN), but a direct connection between this activity and movement difficulties has not yet been established. A study group at Osaka University developed a neurofeedback system which enables patients with Parkinson’s disease to voluntarily control beta wave activity in their deep brain […]

New immune response regulators

The discovery was published in the new iScience journal for interdisciplinary research by Cell Press. The newly discovered regulatory proteins differ significantly from the regulators in mouse immune cells which have been reported earlier. Some of the proteins, such as SATB1 regulating the transcription of several genes, function in the opposite way in human compared […]

Sleeping sickness parasite uses multiple metabolic pathways

Parasitic protozoa called trypanosomes synthesize sugars using an unexpected metabolic pathway called gluconeogenesis, according to a study published December 27 in the open-access journal PLOS Pathogens by David Horn of the University of Dundee in the UK, and colleagues. The authors note that this metabolic flexibility may be essential for adaptation to environmental conditions and […]
