Uranium in the Environment : Mining Impact and Consequences

Uranium is an element to be found ubiquitous in rock, soil, and water. Uranium concentrations in natural ground water can be more than several hundreds µg/l without impact from mining, nuclear industry, and fertilizers. Considering the WHO recommendation for drinking water of 15 µg/l (has been as low as 2 µg/l before) due to the chemical toxicity of uranium the element uranium has become an important issue in environmental research. Besides natural enrichment of uranium in aquifers uranium mining and milling activities, further uranium processing to nuclear fuel, emissions form burning coal and oil, and the application of uranium containing phosphate fertilizers may enrich the natural uranium concentrations in soil and water by far.

The Paraoxonases : Their Role in Disease Development and Xenobiotic Metabolism

Research into the paraoxonase (PON) multigene family has really only blossomed in the last 10 years. Before this time only PON1 was known and research was restricted to toxicologists investigating the metabolism of organophosphate insecticides and nerve gases and a few “mad” scientists searching for “natural” substrates. Since this time two new members PON2 and PON3 have been discovered, all 3 PONs have been shown to act as antioxidants and the PON family has taken centre stage as major players in the development of a wide variety of diseases such as cardiovascular disease, diabetes mellitus, rheumatism, Alzheimer and many more while remaining important in determining organophosphate toxicity.

Textile toxicity

Explores the toxicological implications of various chemicals commonly used in textile manufacturing, including trace elements, flame retardants, benzothiazoles/benzotriazoles, and formaldehyde. Trace elements such as chromium, lead, and antimony, commonly present in clothing, are associated with skin irritation, allergic reactions, systemic toxicity, and carcinogenicity. Flame retardants, particularly brominated and organophosphate types, are linked to endocrine disruption, reproductive toxicity, and developmental harm. Benzothiazoles and benzotriazoles are pervasive in textiles and can permeate the skin, disrupt hormones, and impair neurodevelopment, especially in male offspring during prenatal exposure.

Molecular Biology of the Parathyroid

Caintaining extracellular calcium concentrations within a narrow range is critical for the survival of most vertebrates. PTH, together with vitamin D, responds to hypocalcemia to increase extracellu­ M lar calcium levels, by acting on bone, kidney and intestine. The recent intro­ duction of PTH as a major therapeutic agent in osteoporosis has directed renewed interest in this important hormone and in the physiology of the parathyroid gland. The parathyroid is unique in that low serum calcium stimulates PTH secretion. As hypocalcemia persists, there is also an increase in PTH synthesis. Chronic hypocalcemia leads to hypertrophy and hyper­ plasia of the parathyroid gland together with increased production of the hormone. Phosphate is also a key modulator of PTH secretion, gene expres­ sion and parathyroid cell proliferation. Understanding the biology of the parathyroid as well as the mecha­ nisms of associated diseases has taken great strides in recent years. This book summarizes the molecular mechanisms involved in the function of the para­ thyroid gland. The first chapter reviews the development of the parathyroid gland and the genes involved in this process as identified using genetically manipulated mice. Then the biosynthetic pathway of PTH from gene ex­ pression to its intracellular processing and the sequences in the gene control­ ling its transcription as well as those regulating mRNA processing, stability and translation are described.

Microbial Phosphate Solubilization

Last decade has seen a significantly increased knowledge about phosphate solubilizing microorganisms. Sixty specialists from thirteen countries met in Salamanca to discuss the problems of the high P-unavailability as a soil nutrient for crops, and the hazards of an increasing phosphate input to aquatic habitats from industrial and mining activities, sewage disposal, detergents, and other sources. Updated solutions to enhance P-uptake by plants, bioremediation potential in the rehabilitation of ecosystems, taxonomic characterization interactions with mycorrizae, the physiological and molecular basis of PSM, and possibilities of genetic modifications of rhizospheric microorganisms were among the contributions presented. Challenges in commercializing a phosphate solubilizing microorganism were also outlined by a relevant biotech company.

Glucose-6-phosphate dehydrogenase deficiency

Glucose-6-phosphate dehydrogenase deficiency, the most common enzyme deficiency worldwide, causes a spectrum of disease including neonatal hyperbilirubinemia, acute hemolysis, and chronic hemolysis. Persons with this condition also may be asymptomatic. This X-linked inherited disorder most commonly affects persons of African, Asian, Mediterranean, or MiddleEastern descent. Because acute hemolysis is caused by exposure to an oxidative stressor in the form of an infection, oxidative drug, or fava beans, treatment is geared toward avoidance of these and other stressors.

CO-ENZYME Q10

Coenzyme Q10 (CoQ10) is a fat-soluble compound that is synthesized by the body and can be obtained from the diet. Co-Q10 plays a central role in mitochondrial oxidative phosphorylation and the production of adenosine triphosphate (ATP). It also functions as an antioxidant in cell membranes and lipoproteins. Endogenous synthesis and dietary intake provide sufficient C0- Q10 to prevent deficiency in healthy people, although coenzyme Q10 concentrations in tissues decline with age. Oral supplementation of coenzyme Q10 increases coenzyme Q10 concentrations in plasma and lipoproteins. Oral high-dose co- Q10 is usually effective to treat mitochondrial disorders that are caused by mutations in coenzyme Q10 biosynthetic genes.

Bone disorders

• Bone is the specialized type of connective tissue that has extracellular matrix containing calcium salts. • As bone is a connective tissue, it consists of cells and matrix. • Mineralized extracellular matrix provides hardness to bones. • Bone is a living tissue that shows dynamic structural changes in response to physical stress and hormonal changes. • In addition to support and protection of vital organs, bones act as a storehouse for calcium and phosphates. • Bone also performs hematopoietic function (production of blood cells).
