chemical stability) of Gemcitabine Injection solution by a stability-indicating liquid chromatography method The proposed research study is intended to determine the degradation kinetics of gemcitabine injection solution by applying the stability-indicating liquid chromatography method. This is based on the awareness that kinetics of chemical compounds can be studied when in aqueous solutions with the intention of determining activity at different concentrations. This information would be useful in the formulation of gemcitabine as an antitumor agent that inhibits DNA synthesis to bring about cellular apoptosis (Jansen et al. 885), although Liu, Zhao and Li (1793) it is best used in combination with...

chemical used in this production is Ethyl Alcohol 200 proof which is highly flammable and can have adverse effects when it comes to contact with human or animal body. The Lab has clearly outlined some safety measures to help in case of any direct contact with this chemical. The lab has also been designed in such a way that in the case of any fire, the reaction time to put it out is minimized. This is through the installation of automated sprinklers and heat sensors. There is also multiple refrigerators that help in keeping Ethyl Alcohol 200 proof cool at all times. The key problem is that all the safety requirements, according to National Fire Protection Association (NFPA), have not been met. This...

Chemicals in Product Packaging Products come in a variety of packaging these days and some food items have chemicals identified as suspects, such as phthalates and bisphenol, or BPA. CNN Health’s Sandee LaMotte states that many scientists have suspicions that the packaging could be affecting humans in the endocrine system. This article suggests that customers use their purchasing power to make these companies force changes in the marketplace by insisting that they reduce the harmful chemicals from their products. A group called Safe Chemicals announced a new method for reporting on retailers and assigning a grade to how well these companies are doing in the reduction of harmful chemicals. The...

chemical compound in which at least one hydroxyl group is replaced by O-alkyl group. Esters are formed from an interaction between carboxylic acid and alcohol. Esters are viable compounds which have different commercial and biological implications. Glycerides and triglycerides are important biological esters. These compounds are esters of fatty acids with glycerol. Glycerides and triglycerides are one of the main classes of lipids. Different animal fats and vegetable oils are comprised of glycerides and triglycerides. Phosphoesters forms the major structural backbone of nucleic acids. The molecular weights of these esters are usually high. The molecular weight of the ester depends on upon the...
chemical, social and environmental factors. When a person has depression, it is a sign that some emotional, physical, and social aspects of their life are not adding. Some other impromptu and significant occurrences in life such as loss of loved ones, being caught up in a major felony, being robbed of everything or news of deportation could bring about depression. As far as an occurrence lead one to either loss of self-identity, the self-esteem or causes adverse changes in their lifestyle, then they become the primary causes of depression. Apparently, the causes may not be immediate and require the diagnosis and evaluation by a trained mental doctor. Apart from the direct causes depression can also...

chemical that binds to DNA fragments. A photographic film is utilized to detect the existence of radioactivity; it turns dark at the occurrence of radiation generating a ‘bar code' like appearance ("BBC - GCSE Bitesize Science - Gene technology: Revision", n.d.). The information on genetic engineering provides a background of understanding aspects of genes and how they are manipulated through genetic engineering to improve human life. The article also provides a more elaborative explanation of the importance of biological concepts like the study of microorganisms, enzymes and DNA. Studying biology provides a background for understanding broad science topics like gene technology. With a biology...
