about these aggressive cancers was the protein TOPK. This protein is produced in many human cancers and is thought to encourage the growth of tumors. Professor Yusuke Nakamura wanted to target this protein with the new drug that lowered levels of toxicity while still shrinking tumors- this drug ended up being named OTS964. In order to test the drug‚ six mice with LU-99 lung tumors were injected with the drug and studied over a period of two weeks. All the mice recovered from the tumors. In five

different oxidative states like trivalent Cr (III) and hexavalent chromium Cr(VI). Both these states differ in different aspcets like mobility‚bioavailabilty and toxicity (Shanker et al‚.2005;Panda and Choudhory ‚.2005). Toxic effects of chromium highly depend on the different states of the oxidative states. As the solubility and toxicity of the trivalalent chromium Cr+3 form is less than hexavalent chromium Cr+6 form ( Pandey and Sharma‚. 2003). Hexavalent chromium is converted to trivalent chromium

They are preferred over organophosphates and carbamates due to their high efficacy against a wide variety of insects‚ low mammalian toxicity and easy biodegradability. Cypermethrin (CYP)‚ a synthetic pyrethroid‚ is largely used for such purposes as it has a wide safety margin in mammals (Khan et al.‚ 2009). The technical grade CYP is a racemic mixture of eight isomers (four cis and four

have agreed upon a classification due to the oils viscosity‚ volatility and toxicity. Viscosity refers to the oils slimines. The oils with higher viscosity are much harder to pump from the ground and rafine. Oils volatility depends on the ability of the oil to evaporate into air. If the volatility is too high‚ people have to take special precautions so they will during distillation lose as little oil as possible . Toxicity‚ as can be understood from the name‚ refers

tests are carried out on these animals each year. Types of tests include acute toxicity test‚ chronic toxicity test‚ skin irritation tests‚ acute inhalation toxicity tests‚ psychology research‚ and weapons tests as listed by People for the Ethical Treatment of Animals or PETA (PETA fact sheet 2). An acute toxicity test is where certain chemicals are force fed to an animal to find out the lethal dosage. Chronic toxicity test is to find out whether or not a chemical can be harmful in small dosages

It is important for consumers to consider the toxicity of mercury when purchasing or even eating seafood. Health concerns should be “a major reason motivating individuals to limit their consumption of [mercury based products]” (Fox and Ward 188). Many articles proposed that mercury toxicity is associated with changes in brain‚ kidney and nervous system damage. It is recommended that consumption of mercury be minimized
