Severe poisoning resulting from single ingestions of rodenticides, herbicides, or insecticides containing arsenic have been frequently recognized. We record three cases of solubilized arsenic trioxide poisoning in Navajo Indian children and one case of sodium arsenate ingestion in an infant. One fatality occurred during dimercaprol therapy prior to initiation of therapy with D-penicillamine. Th...

This basic socio-cultural framework, with all its inherent ambivalences and contradictions, emerged during the colonial era and exercised a deep and lasting impact on the political, economic and social structure of the new South American nations. Only after many decades was the impact blurred by the action of other external influences, change occurring from within, and a growing sense of nation...

• Absorption of arsenic is largely dependent on the solubility and particle size • Concentrations of arsenic or its metabolites in blood, hair, nails and urine may be used as biomarkers of arsenic exposure • Blood arsenic is a useful biomarker only in the case of acute arsenic poisoning or stable chronic high-level exposure • Since the elimination of arsenic takes place mainly via the kidneys, ...

Coulomb, Carl Friedrich Gauss, André Marie Ampère, and Michael Faraday discovered the four experimental laws concerning electricity and magnetism, James Clerk Maxwell added the displacement current and thereby created the great set of Maxwell’s equations. That view is not entirely wrong, but it obscures the subtle interplay between sophisticated geometrical and physical intuitions that led not ...

Introdution Chronic arsenic poisoning in China resulting in endemic arsenicosis in vast areas particular in rural areas, was first observed in the 50’s and subsequently in the late 1970’s and early 1980’s in different localities. In China, chronic arsenic poisoning can be classified into two types based on the sources of arsenic intake into the human body. These are collectively known as Drinki...

In contrast to arsenic (As) poisoning caused by naturally occurring inorganic arsenic-contaminated water consumption, coal arsenic poisoning (CAP) induced by elevated arsenic exposure from coal combustion has rarely been reported. In this study, the concentrations and distributions of urinary arsenic metabolites in 57 volunteers (36 subjects with skin lesions and 21 subjects without skin lesion...

Arsenic is natural metalloid which is present in the universe everywhere. It is used for different insecticides and pesticides preparation. Poisoning of arsenic is a major issue that affects different species. Its occurrence is related to contamination of feed and water; therefore, it is matter of concern globally. However, its level of toxicity is increasing very rapidly in Asian countries esp...

Arsenic poisoning interferes with cellular longevity by allosteric inhibition of an essential metabolic enzyme pyruvate dehydrogenase (PDH) complex which catalyzes the reaction Pyruvate + CoA-SH + NAD+ PDH Acetyl-Co-A + NADH + CO2. With the enzyme inhibited, the energy system of the cell is disrupted resulting in a cellular apoptosis episode. Biochemically, arsenic prevents use of thiamine resu...

Background: Datura stramonium is a poisonous and common flowering plant that is a member of the Solanacae family. Datura poisonings are a rare occurrence in the 21st century, making toxicological information on this plant sparse. Historical information on Datura provides useful information on the clinical symptoms and characteristics of poisonings. This review looks at the state of knowledge on...

The life of 19th century Swedish chemist cum inventor Alfred Nobel can be conveniently divided into two equal phases: pre-nitroglycerine phase (1833-1863) and nitroglycerine phase (1864-1896). According to the records of Ragnar Sohlman, his assistant during his last year of life, Nobel's physical condition began to decline towards the end of the 1870s, and for the last 16 years he suffered from...
