The bioavailability of lead in kidney is mediated in part by binding to endogenous high-affinity cytosolic lead-binding proteins (PbBP), which are not detectable in liver. Addition of semipurified 11,500 dalton PbBP to liver delta-aminolevulinic acid dehydratase (ALAD) reaction mixtures reverses inhibition of this enzyme by lead and thus provides an explanation for the relative insensitivity of...

background the amount of effective ingredient production in plants is influenced by various climatic and environmental factors such as quality of water resources, soil quality, air quality, and the level of environmental pollutants. objectives in this research, we seek to study and analyze the qualitative effects of heavy metals on the respiratory organ of rosemary. further, we will compare the...

Lead is a toxic substance that attacks many different body organs and systems. Unlike other metals such as zinc or iron, lead has no beneficial effects on the body. Lead is a ubiquitous environmental contaminant, largely due to the wide variety of past and present commercial uses. It is one of the best-studied toxic substances. Lead poisoning is considered by the Centers for Disease Control and...

Epilepsy is a disorder categorized by recurrent seizures and leads to changes in neuronal death and neurogenesis. Recently the search for new targets in the therapy of epilepsy has focused on brain inflammation because brain inflammation and the associate blood brain barrier damage appears to be basic part of epilepsy pathophysiology-erythropoietin (EPO) regulates biological processes counting ...

background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

Heavy metals pose a risk of contaminating groundwater and surface water sources due to geogenic activities, industries and agricultural sources. The removal of heavy metals e.g., cadmium, lead, and zinc from drinking, industrial and irrigation water at low concentrations is a recurring challenge, especially in developing countries. Biosorption is a relatively new process that has proved to be v...
