Journal ArticleDOI
Gender differences in autoimmune disease.
TL;DR: Gender differences in systemic and organ-specific autoimmune diseases are considered, and human data is summarized that outlines the prevalence of common autoimmune diseases specific to adult males and females in countries commonly surveyed.
Journal ArticleDOI
Neuronal Lipid Metabolism: Multiple Pathways Driving Functional Outcomes in Health and Disease.
TL;DR: Current knowledge of the roles of lipid metabolism and function in the CNS are reviewed and how modulating these pathways may offer novel therapeutic options for treating ALS is discussed.
Journal ArticleDOI
Development of a methodology for and assessment of pulsatile luteinizing hormone secretion in juvenile and adult male mice
TL;DR: A highly sensitive ELISA is developed for assessment of mouse LH concentrations in small fractions of whole blood that is capable of reliably detecting LH down to a theoretical limit of 0.117 ng/mL in a 2-μL fraction of wholeBlood.
Journal ArticleDOI

TL;DR: Hypermetabolic patients with ALS have a greater level of lower motor neuron involvement, faster rate of functional decline and shorter survival, and the metabolic index could be important for informing prognosis in ALS.
Journal ArticleDOI
Pregnancy-Induced Adaptation in the Neuroendocrine Control of Prolactin Secretion
TL;DR: The changing patterns of prolactin secretion during pregnancy in the rat is described and the neuroendocrine mechanisms controlling these changes are discussed, and dopamine secretion from TIDA neurones is reduced during late pregnancy.
