Lead is a ubiquitous environmental pollutant that poses serious health problems to humans, especially children. However, genetic variability in individuals varies their susceptibility lead poisoning. One possible factor polymorphism. Thus, this study aimed investigate the association between blood level (BLL), and polymorphisms delta-aminolevulinic acid dehydratase (ALAD) MspI (rs1800435) vitam...

L\'{a}szl\'{o} Fejes T\'{o}th and Alad\'{a}r Heppes proposed the following generalization of kissing number problem. Given a ball in $\mathbb{R}^d$, consider family balls touching it, another first family. Find maximal possible this arrangement, provided that no two intersect by interiors, all are congruent. They showed answer for disks on plane is $19$. also conjectured if there three families...

The authors conducted a 2003-2007 case-control study including 184 cases and 194 controls to examine the association between blood lead and the risk of amyotrophic lateral sclerosis (ALS) among US veterans and to explore the influence on this association of bone turnover and genetic factors related to lead toxicokinetics. Blood lead, plasma biomarkers of bone formation (procollagen type 1 amino...

Lead is known to cause harmful effects in the haematopoietic, nervous, digestive, renal, and other organ systems, inhibiting a number of enzymes in the biosynthesis of haem, as well as other enzymes with haematological significance. Our study involved 151 employees involved with the cutting of crystal, i.e. leaded glass, who had been found using eco-monitoring to have been exposed to above norm...

The most sensitive method used in monitoring the blood lead-level is atomic absorption spectrophotometry. Its limitation due to its high cost has made delta-aminolaevulinic acid dehydratase (delta-ALAD) inhibition more popular. This work demonstrates that ceruloplasmin (Cp), the blue-colored copper containing alpha-2 globulin (alpha(2) globulin) glycoprotein in serum, can serve as a high-potent...

Effects of Lead on the Induction of Hepatic Microsomal Enzymes by Phenobarbital and 3,4Benzpyrene. CHOW, C. P. AND CORNISH, H. H. (1978). Toxicol. Appl. Pharmacol. 43,219-228. A single ip injection of lead acetate (65 mg/kg) prolonged the duration of zoxazolamine paralysis in Sprague-Dawley rats and prevented the stimulation of zoxazolamine metabolism normally induced by phenobarbital. Lead als...

Medina lagoon in Andalusia has one of the highest densities of spent lead (Pb) shot in Europe. Blood samples from waterbirds were collected in 2006-2008 to measure Pb concentration (PbB), δ-aminolevulinic acid dehydratase (ALAD), oxidative stress biomarkers and plasma biochemistry. PbB above background levels (>20 μg/dl) was observed in 19% (n=59) of mallards (Anas platyrhynchos) and in all com...

We live-trapped 40 northern pocket gophers across two years from the Anaconda Smelter Superfund Site, Anaconda, Montana, USA, to determine their exposure to five metal contaminants and effects of exposure on selected measurements. Soil, gopher blood, liver, kidney, and carcass samples were analyzed for arsenic, cadmium, lead, copper, and zinc. Hematological parameters, kidney and liver porphyri...
