Why does fasting reduce seizures?
by Children’s Hospital Boston Graphical abstract. Credit: Cell Reports (2022). DOI: 10.1016/j.celrep.2022.111278 Calorie restriction has long been associated with reduced seizures in epilepsy. New research from Boston Children’s Hospital helps explain how fasting affects neurons in the brain and could lead the way to new approaches that would avoid the need for fasting or restrictive diets. The...

Severe COVID-19 impairs the immune system for longer than 6 months
by Linköping University Graphical outline of the study. Peripheral blood was collected from patients with COVID-19 that needed hospitalization (N=46) and healthy controls (N=31). Clinical parameters were measured at enrollment, and the levels and effects on peripheral immune cells and neutralizing antibodies were assessed at enrollment, 2 weeks, 6 weeks, and 6-8 months. The phenotype...
Researchers identify a potential path against inherited neurological disease
by The Mount Sinai Hospital Researchers at the Icahn School of Medicine at Mount Sinai and NCATS identified compounds that reversed the effects of several neurodegenerative diseases called lysosomal storage disorders (LSDs) in patient cells and mice. LSDs are characterized by genetic defects that prevent the cell’s lysosomes from breaking down and recycling fats, sugars...
Experimental drug shows promise against lupus
by Denise Mann An experimental drug that has been shown to treat rashes in people with lupus may also help with lupus-related joint pain. Affecting as many as 1.5 million people in the United States, lupus is an autoimmune disease in which the body’s immune system misfires against its own joints, skin, brain, lungs, kidneys and blood...
