PURPOSE Polymicrogyria (PMG) is an epileptogenic malformation of cortical development. We describe the clinical epilepsy and imaging features of a large cohort with PMG-related epilepsy. METHODS Participants were recruited through the Epilepsy Phenome/Genome Project, a multicenter collaborative effort to collect detailed phenotypic data on individuals with epilepsy. We reviewed phenotypic dat...

BACKGROUND NGAL is involved in modulation of the inflammatory response and is found in the sera of uremic patients. We investigated whether hemodiafiltration (HDF) could influence the ability of polymorphonuclear granulocytes (PMGs) to release NGAL. The involvement of interleukin- (IL-)1β and tumor necrosis factor- (TNF-)α on NGAL release was evaluated. METHODS We studied end-stage renal dise...

The Drosophila CNS contains a variety of glia, including highly specialized glia that reside at the CNS midline and functionally resemble the midline floor plate glia of the vertebrate spinal cord. Both insect and vertebrate midline glia play important roles in ensheathing axons that cross the midline and secreting signals that control a variety of developmental processes. The Drosophila midlin...

BACKGROUND Polymicrogyric cortex demonstrates interindividual variation with regard to both extent of dyslamination and functional capacity. Given the relationship between laminar structure and white matter fibers, we sought to define the relationship between polymicrogyria (PMG), intrahemispheric association pathways, and network function. METHODS Each arcuate fasciculus (AF) was categorized...

A number of familial syndromes of bilateral polymicrogyria (PMG) have been described, but reported unilateral PMG cases have generally been sporadic. The authors identified four families in which unilateral right-sided PMG on MRI was present in more than one individual, with pathologic confirmation in one. Core clinical features included contralateral hemiparesis, developmental delay, and focal...

The epidermis, by invagination of the undifferentiated ectodermal cells, gives rise to several distinct structures including hair, sebaceous, eccrine sweat and mammary glands. We have recently isolated a novel gene, pmg-1, expressed in the pubertal mouse mammary gland. While investigating its genomic structure, we identified a related gene in close proximity, which we have termed pmg-2. pmg-1 a...

PURPOSE The aim of this study was to evaluate the effects of pomegranate (PMG) extract and carvacrol (CARV) on methotrexate (MTX)-induced oxidative stress and bone marrow toxicity. METHODS Wistar albino rats (32 rats) were divided into four groups (n=8): Group 1 was control; Group 2 was given a single intraperitoneal injection of methotrexate (20 mg/kg); Group 3 was treated with carvacrol (73...

This study reports for the first time a relationship between dietary Mg and the renal thiazide-sensitive Na-Cl cotransporter (TZR, measured by saturation binding with 3H-metolazone). Ion-selective electrodes measured plasma ionized magnesium (PMg++), calcium (PCa++), and potassium (PK+). Restricting dietary Mg for 1 wk decreased PMg++ 18%, TZR 25%, and renal excretion of magnesium (UMg) and cal...

Resumption of meiosis was inhibited in mouse oocyte cumulus complexes (OCC) co-cultured with pig membrane granulosa (PMG). After 3 and 6 h of co-culture these oocytes possessed an intact nuclear envelope and their nucleolar surface was associated with granules approximately 80 nm in diameter. Preincubation of OCCs for 30, 45, 60 or 90 min followed by co-culture with PMG for 2 h of either OCCs o...

PURPOSE To study the effect of a peer mentoring group (PMG). METHOD Six junior clinician educator faculty and one senior faculty at the University of Washington Medical Center's Department of Psychiatry formed a PMG in 2006. The PMG had 30 meetings during 2006-2010. Group format, goals, and meeting agendas were determined solely by participants. Feedback about positive and negative outcomes o...
