Garages and auto-repair workshops may be polluted with other heavy metals besides lead. Blood of autoworkers with high lead content was analysed for cadmium, chromium, copper manganese, nickel, ALAD activity and carboxyhaemoglobin level. Cadmium and copper levels in blood of autoworkers were comparable with those of the control subjects while chroimium and nickel levels were significantly highe...

Introducción. En Perú se usan múltiples definiciones de síndrome metabólico (SM); sin embargo, actualmente no hay un consenso sobre cuál definición usar en la práctica clínica. Objetivos. Comparar las estimaciones riesgo cardiovascular (RCV), obtenidas mediante calculadora RCV ACC/AHA, y evaluar su grado concordancia con diferentes SM pacientes atendidos Lima, Perú. Materiales métodos. Estudio ...

BACKGROUND Lead poisoning affects many organs in the body. Lead inhibits delta-aminolevulinic acid dehydratase (ALAD), an enzyme with two co-dominantly expressed alleles, ALAD1 and ALAD2. OBJECTIVE Our meta-analysis studied the effects of the ALAD polymorphism on a) blood and bone lead levels and b) indicators of target organ toxicity. DATA SOURCE We included studies reporting one or more o...

5-Aminolevulinic acid dehydratase (ALAD) activity in two patients with compound heterozygous 5-aminolevulinic acid dehydratase deficiency porphyria was studied over the last 20 years. The patients' enzyme activity was <10% from 1977 to 1997. An acute crisis in each patient was successfully treated by infusion of glucose and heme arginate. After this therapy both urinary 5-aminolevulinic acid (A...

A cross-sectional analysis was performed to evaluate associations of polymorphisms in the vitamin D receptor (VDR), delta-aminolevulinic acid dehydratase (ALAD), and endothelial nitric oxide synthase (eNOS) genes with patella lead concentrations in 652 lead workers in the Republic of Korea. There was a wide range of patella lead (from below detection limit to 946 microg Pb/g bone mineral), with...

Latin America faces unique challenges in the treatment of type 2 diabetes mellitus. The Asociación Latinoamericana de Diabetes (Latin American Diabetes Association, ALAD) brought together medical associations in 17 countries in Latin America to produce a consensus statement regarding the treatment of type 2 diabetes. The goal of the document is to provide practical recommendations that will gui...

Critical Dose of Lead Affecting δAminolevulinic Acid Levels: Katsuyuki MURATA, et al. Akita University School of Medicine—To estimate the critical dose of the association between the blood lead concentration (BPb) and δ-aminolevulinic acid (ALA) levels, ALA levels in plasma (ALA-P), blood (ALAB), and urine (ALA-U), and the activity of δaminolevulinic acid dehydratase (ALAD) were determined in 1...

Non-crystalline photonic band gap (PBG) materials have received increasing attention, and sizeable PBGs have been reported in quasi-crystalline structures and, more recently, in disordered structures. Band structure calculations for periodic structures produce accurate dispersion relations, which determine group velocities, dispersion, density of states and iso-frequency surfaces, and are used ...
