. Update Article NSAIDs and Kidney P Ejaz‚ K Bhojani‚ VR Joshi* Abstract NSAIDs are commonly used drugs. Even with the advent of selective COX-2 inhibitors‚ nephrotoxicity still remains a concern. The adverse effects of NSAIDs are mediated via inhibition of prostaglandin synthesis from arachidonic acid by non-specific blocking of the enzyme cyclooxygenase leading to vasoconstriction and reversible mild renal impairment in volume contracted states. When unopposed‚ this may lead to acute tubular

Homeostasis: The process of the body maintaining a constant internal environment‚ despite any external changes. Homeostasis ensures that the following are kept the same: Body temperature Amount of water in our body Blood glucose levels Breathing rate Heart rate How are things kept the same? 1. Receptors: They detect a change in the things such as temperature 2. Processing: Centre receives information and coordinates a response 3. Effects: Produce a response that ensures our body temperature stays

Goldfish Respiration Abstract The purpose of this experiment is to design and conduct a basic scientific experiment‚ identify and control variables. Some other objectives that we learned is to write a formal hypothesis‚ identify the basic and integrated process skills of science that were used in this experiment. Also‚ we will learned the effects of temperature on goldfish respiration. This experiment will be conducted with four students ‚ one goldfish‚ thermometer‚ a stop watch‚ and a beaker

around the plant as needed. The mesophyll cells have chloroplasts and this is where photosynthesis occurs. Respiration can be defined as the oxidation of the end products of glycolysis with the storage of the energy in the form of ATP. Cellular respiration occurs when oxygen is available‚ and the products are carbon dioxide and water. There are three main pathways in the cellular respiration process. These are: pyruvate oxidation‚ the citric acid cycle‚ and the respiratory chain. Pyruvate oxidation

Martin 03/08/2010 The Ford Pinto Case and Utilitarianism In this essay‚ I will talk about the ford Pinto case‚ and how the information was withheld from public in order to save company from huge losses and at the same time keep company’s reputation intact. I don’t think the decision of the ford company to with hold the information about the safety-issue of the car for which they were already aware of; was the right thing to do. I agree‚ as a utilitarian

Photosynthesis and Respiration Objectives: In this activity we will review the process of photosynthesis and cellular respiration‚ and become familiar with the use of a pH indicator for investigating these processes. Following this activity your group will generate a new research question about photosynthesis or respiration‚ and utilize the pH indicator system for the experiment that your group will design‚ implement and interpret. Introduction: Photosynthesis is the process by which plants and

“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens

osmolality constant. In humans the kidney plays a huge part in the osmoregulation of the body’s internal environment. Regulation of water in the human body is carried out through the excretion of waste urine from the body. Hormones which include: the antidiuretic hormone‚ aldosterone and angiotensin II are used in the body to help to increase the permeability of the collecting ducts found in the kidney. This further allows diffusing to occur easily‚ it also allows the kidney to be able to reabsorb water

Abstract The effect of nature of substrates on the rate of cellular respiration in yeast was determined by using the Smith fermentation tube method. Mixtures of 15ml distilled H2O‚ 10% yeast suspension and 15ml of the following solutions (all at 10% concentration):1- starch‚ 2 – lactose‚ 3 – sucrose‚ 4 – glucose‚ 5 – fructose‚ 6 – distilled water ‚ were poured in six smith fermentation tubes. Cotton balls were plugged in the openings of the tubes and the tubes were kept upright and observed for
