Acetate Causes Alcohol Hangover Headache In Rats., Christina R Maxwell, Rebecca Jay Spangenberg, Jan B Hoek, Stephen D Silberstein, Michael L Oshinsky

Department of Neurology Faculty Papers

BACKGROUND: The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache.

METHODS: We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats.

RESULTS: Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate …

Ms4a4b, A Cd20 Homologue In T Cells, Inhibits T Cell Propagation By Modulation Of Cell Cycle., Hui Xu, Yaping Yan, Mark S Williams, Gregory B Carey, Jingxian Yang, Hongmei Li, Guang-Xian Zhang, Abdolmohamad Rostami

MS4a4B, a CD20 homologue in T cells, is a novel member of the MS4A gene family in mice. The MS4A family includes CD20, FcεRIβ, HTm4 and at least 26 novel members that are characterized by their structural features: with four membrane-spanning domains, two extracellular domains and two cytoplasmic regions. CD20, FcεRIβ and HTm4 have been found to function in B cells, mast cells and hematopoietic cells respectively. However, little is known about the function of MS4a4B in T cell regulation. We demonstrate here that MS4a4B negatively regulates mouse T cell proliferation. MS4a4B is highly expressed in primary T cells, natural …

Introduction

Mutations in the POLG1 gene are considered to be the most common gene defect identified in autosomal recessive mitochondrial DNA depletion disorders. POLG1 is a gene encoding the 195kDa catalytic (alpha) subunit of the mitochondrial (gamma) DNA polymerase, located on chromosome 15q25 and is responsible for mtDNA replication. Mutations in POLG1 are associated with chronic progressive external ophthalmoplegia (CPEO). Other genes that have been implicated in causing syndromic and non-syndromic mitochondrial disorders have been found on both mtDNA (3243A>G, 8344A>G, 8993T>G, and 11778A>G) and nDNA (SURF1, POLG1, TWINKLE, and ANT1).

We report a patient with …
