lead belongs to the heavy metal group and is considered as an environmental contaminant. acute or chronic contact to lead can change the physiological function of human organs. one of the most important disorders following the lead exposure is neurotoxicity. lead neurotoxicity consists of the neurobehavioral disturbances like cognitive impairment. the aim of the current study is to evaluate the...

In the title complex, {[Pb(C(8)H(7)O(3))(2)(H(2)O)]·H(2)O}(n), the Pb(II) atom is seven-coordinated by six carboxyl-ate O atoms from four different 2-hydroxy-phenyl-acetate (2-dph) ligands and one water mol-ecule, displaying a hemidirected irregular geometry, with the empty side of the metal ion capped by a benzene ring forming a Pb⋯π contact [Pb⋯centroid distance = 3.342 (2) Å]. One 2-dph liga...

Willow (Salix spp.) stands are often proposed as vegetation covers for the restoration and stabilization of contaminated and derelict land. Planting willows on dredged sediment disposal sites for biomass production can be an alternative to traditional capping techniques. However, with the introduction of willow stands on dredged sediment disposal sites, the possibility of increased contaminant ...

Chronic exposure to lead (Pb) affects neural functions in central nervous system (CNS) particularly the learning and memory. On the other hand, alteration of calcium level in the CNS results in activation of NOS. It has been shown that lead enters the neurons through calcium channels and displaces Ca2+ from calcium binding proteins such as calmodulin and troponin C thereby affecting calcium-med...

Background: This study was undertaken to investigate whether treatment with vitamin E and N acetyl cystein protects rat sperm by inhibiting reactive oxygen species generation induced by lead (Pb) exposure. Materials and Methods: After an acclimatization period of one week, 20 Male rats were divided into 4 groups of 5 rats each. Animals within different treatment groups were maintained on their ...

Introduction: Lead intoxication in children has been associated with neurodevelopment disabilities that may result in motor and cognitive impairment. The aim of the present study is to evaluate in long term effects of prenatal exposure to low-level Pb2+ on learning, memory and EEG. Materials & Methods: Rat pregnant were exposed to distilled water or 0.05, 0.1, 0.2 % of Pb-acetate in the dr...
