less toxic form tellurium Te0 intracellularly. The result is the accumulation of black deposits inside the cell is due to either internal or periplasmic accumulation of Te. Tellurite toxicity results from its ability to act as a strong oxidizing agent over a variety of cell components. Tellurite could exert its toxicity through intracellular generation of reactive oxygen species (ROS). Tellurite inhibits the cellular response to oxidative stresses. To inhibit the growth of most normal bacterial inhabitants

disaster in Bhopal‚ India‚ happened because of inadequate maintenance by Union Carbide and poor monitoring by the Indian authorities. Malfunctioning safety measures‚ inappropriate location of the plant‚ and lack of information about the identity and toxicity of the gas worsened the effects of the accident on people and livestock. The Bhopal disaster has raised questions about the implications of the transfer of potentially hazardous technology to the developing countries. Even after 20 years‚ Bhopal

ABSTRACT EXAMPLES Writing an Abstract – Examples Each student who completes a science fair project must write an abstract to be displayed with the project. An abstract gives the essence of the project in a brief but complete form — it should not exceed 250 words. Judges and the public should have a fairly accurate idea of the project after reading the abstract. The abstract must focus on the current year’s research and give only minimal reference to previous work. Details and discussions should

that can apply to vitamins. The body needs vitamins to function properly‚ but high doses of certain vitamins can be toxic‚ especially fat soluble vitamins that the body stores for long periods of time. Water Soluble Vitamins Water-soluble vitamin toxicity is rare because the body does not store water-soluble vitamins and excess amounts are usually excreted in urine. Side effects associated with water-soluble vitamins occur due to intake of extremely high doses. Peripheral neuropathy‚ a nerve disorder

Reflective paper Animal Rights When it comes to animals and their rights‚ there is a definite line between our needs and our taking advantage of those species that we consider inferior. As long as man has existed he has been carnivorous‚ and the same holds true for many other species of animals. Animals are a necessity to humans for survival‚ whether it be for food‚ clothing‚ etc. However‚ the unnecessary torture of animals through testing is not a necessity for human survival. When it comes to

dietary patterns‚ gender‚ life style and many such factors all contribute to determining the drug efficacy and toxicity making the process really challenging. At a broad level a drug is evaluated based on two metrics Efficacy and Toxicity. Efficacy of a drug is defined in terms of cure or elimination of disease condition and/or only mitigation of disease associated conditions. Toxicity or side-effects is defined as unintended and unwanted impact of the drug which causes or triggers other disease

studies of the predictability of animal experiments consistently show them to be worse than random guesswork. For example‚ in one paper that reviewed drugs whose toxicity to humans caused their withdrawal from the market (1960-1990)‚ only 4 out of 24 cases were predictable from animal data. In another review only 6 of 114 human toxicities had animal correlates. Clearly‚ animal tests are failing to protect people. According to Hospital Doctor journal‚ only one per cent of adverse drug reactions are
