Serum creatinine concentration shows a relationship with GFR‚ making it specific‚ but not a sensitive measure of GFR. The creatinine pool is influenced by nutritional state‚ hepatic disease gender‚ ethnicity‚ protein intake‚ and age (Slack et al.‚ 2010). In liver cirrhosis‚ the decrease in serum creatinine is due to a 50% reduction in hepatic production of creatine; increases in volume of distribution due to accumulation of extracellular fluid‚ ascites‚ edema‚ loss of muscle mass and malnutrition

Determining the Concentration of a Solution: Beer’s Law Purpose: The purpose of the experiment is to determine the concentration and formula of an unknown cobalt nitrate solution by measuring absorbance. Introduction: A Colorimeter will be used to determine the concentration and formula of an unknown cobalt nitrate solution. The colorimeter sends blue light from the LED light source to pass through the solution and hit a photocell. A solution with a higher concentration will absorb more

The Effect of Sugar Type on Rate of Energy Production During Yeast Fermentation Sarah Sulon Biology Lab 111L Dr. Murray October 25 2010 Abstract The experiment was conducted to determine the impact different sugar types have on yeast fermentation. It was hypothesized that glucose‚ sucrose and fructose would all produce energy through yeast fermentation‚ but that sucrose would have the greatest rate of energy production. The carbon dioxide production was tracked in the fermentation of yeast

AbstractThe rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For

Biological Membrane Study: HCl‚ NaOH‚ SDS Objective and Hypothesis: The objective of this lab is to determine the effects of SDS‚ HCl‚ and NaOH on red cabbage cell membrane. Prior knowledge can tell us that the red cabbage is a red-purple color due to a pigment called anthocyanin. This is what we will be testing in the experiment. We also know that HCl is a strong acid (very low pH) and that NaOH is a strong base (very high pH). From information learned in this course (lecture/lab) we can assume

Economy - overviewzz Philippine GDP grew 7.6% in 2010‚ spurred by consumer demand‚ a rebound in exports and investments‚ and election-related spending‚ before cooling to 3.7% in 2011. The economy weathered the 2008-09 global recession better than its regional peers due to minimal exposure to troubled international securities‚ lower dependence on exports‚ relatively resilient domestic consumption‚ large remittances from four- to five-million overseas Filipino workers‚ and a growing business process

Coupled Reactions ABSTRACT A way to drive a non-spontaneous reaction forward is by coupling it with another reaction that is highly spontaneous‚ resulting to a spontaneous overall reaction. In this study‚ since the extraction of C(s) from CO2(s) is a non-spontaneous process‚ it was coupled with the oxide formation reaction of Mg‚ a reaction with high spontaneity‚ so that the process of the extraction of C(s) would proceed. The reactions and products which were a mix of black and white
