Isolation of Chlorophyll and Beta-Carotene from Plant Leaves Yokoyama Yuri B1 (A0142349E) 1. Aim: a) To separate beta-carotene and chlorophyll via column chromatography. b) To analyse the contents of the plant extract as well as the separated beta-carotene and chlorophyll via thin layer chromatography (TLC) c) To analyse the absorption peaks of both beta-carotene and chlorophyll using UV-Vis spectroscopy 2. Results: Fig 1. UV-Vis spectroscopy results for S2 (Beta-Carotene extract) Wavelength at…

environmentally-acquired gene mutations. Cigarette smoke is the predominant form of tobacco consumption consisting of about 95% of tobacco use. There are over 4,000 chemicals in tobacco smoke and at least 69 of those chemicals are known to cause cancer. Acetone, acetic acid, ammonia, butane, formaldehyde, tar, and nicotine are some…

Pathophysiology Insulin is made by special cells called beta cells that are produced by the pancreas. Insulin is used to regulate glucose for metabolism. Insulin allows glucose to enter cells and without this glucose would not enter the cells of the body and blood sugar levels would rise in the blood, resulting in hyperglycemia. This process of high sugar in the blood without metabolism will eventually develop into Diabetes Mellitus. There are two types of Diabetes, Type 1 and Type 2. Either…

Effective clinical reasoning skills are essential in nursing; an estimated half of all clinical adverse events are attributed to errors in clinical decision-making (Levett-Jones et al., 2013). Tanner (2006) defined clinical reasoning as the process via which nurses arrive at clinical decisions by weighing evidence, pattern recognition, using intuition, selecting from alternatives and patient safety. This clinical reasoning cycle (CRC) consists of 8 cyclical steps namely, consideration of the…

Purpose In this experiment, volumetric glassware was used in order to determine the density of an unknown liquid. Additionally, the opposite process was used to determine the calibration of a piece of glassware using a known density. In the first activity, “Density of Liquids”, the identity of a liquid was determined by calculating its density (g/mL). First the mass (g) of a specific volume (mL) of water and the unknown liquid was found. Their densities (g/mL) were then calculated by dividing…

results in rapid shallow breathing (Kussmaul respirations). Ketones/ketoacids/hydroxy acids, in particular, beta-hydroxybutyrate, induce nausea and vomiting that consequently aggravate fluid and electrolyte loss already existing in DKA. Moreover, acetone produces the fruity breath odor that is characteristic of ketotic…

Natural gas is a much needed and demanded resource both locally and internationally. Considerable controversy has risen concerning the methods used for extracting natural gas through the process of hydraulic fracturing. As with any oil and gas operations, there are environmental risks associated with natural gas production. Hydraulic fracturing is a mining or drilling technique used to break up rock underground to create easier access to resources. This process is common in oil drilling and…

Balfour and this was the beginning of the discussion that Palestine should to the Jewish National Home. During World War I, Weizmann's influence and relations with the British government increased, as he lent his talents to producing the solvent acetone (http://www.zionism-israel.com/Balfour_Declaration_1917.htm). After many conversations, negotiations, and promises, on November 2, 1917, the finale draft of the Balfour declaration was issued and it was accepted by the League of Nations on July…

1. Hypothesis Statements We are testing the efficiency of an in vivo tool for screening the effects of anti-cancer drugs on zebrafish embryos and comparing the results and their cytotoxicity with MTT assay of the MCF7 breast cancer cell line. The results will indicate if the drugs have similar effects on both breast cancer cells and zebrafish embryos. It is given that embryogenesis and carcinogenesis have similar molecular mechanisms, therefore it is expected that these cell types act somewhat…

Carbonyl compounds undergo various types of reaction. In these reaction the carbonyl carbon or carbonyl oxygen is prone to attack generally by a nucleophile. Different types of carbonyl compounds undergo different types of reactions and the mechanisms of them are also different. The products or by-products or intermediate products of these reactions are very much useful in laboratory synthesis, industry etc. here we will discuss some very much important reactions which are very important for…
