Pathophysiology of Metastatic Liver Cancer Liver metastases are cancerous tumors that have spread to the liver from somewhere else in the body. Cancers that may spread to the liver include: • Breast cancer • Colorectal cancer • Esophageal cancer • Lung cancer • Melanoma • Pancreatic cancer • Stomach cancer The risk of cancer spreading to the liver depends on the site of the original cancer. A liver metastasis may be present when the original (primary) cancer is diagnosed‚ or it may

on The Activity of The Enzyme Catalase Introductions: Enzmyes are proteins that catalyze chemical reactions. All living things have catalase present in them. Catalase is a common HYPERLINK "http://en.wikipedia.org/wiki/Enzyme" enzyme found in nearly all living organisms that are exposed to oxygen‚ where it HYPERLINK "http://en.wikipedia.org/wiki/Catalyst" catalyzes the decomposition of HYPERLINK "http://en.wikipedia.org/wiki/Hydrogen_peroxide" hydrogen peroxide‚ which is damaging to the cells

I experienced cancer when my father was diagnosed with Liver Cancer in 2013. It was easy for my family and I to provide him with support to alleviate the emotional pain‚ however‚ we weren’t always able to alleviate the physical pain he went through. Fortunately‚ the medication and treatments were able to help

the most abundant thing in the universe? Hydrogen is the answer! Now with a little bit more refining it will be. Good morning fellow students today I will be talking about hydrogen powered vehicles. Firstly‚ some terms need definition.Hydrogen- a colourless‚ odourless‚ flammable gas which is the lightest and simplest of all known elements.Vehicle- A device or structure for transporting persons or things. Secondly‚ now to explain the ways to use hydrogen as a fuel. The first way is called electrolysis

relationship between moles evolved and consumed. This can be demonstrated by measuring the hydrogen gas evolved by performing a chemical experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes; Mg + 2HCl → H2 + Mg2+(aq) + 2Cl- (aq) The major findings contributing to the experiment is being able to determine and distinguish what moles have evolved thus being the hydrogen moles evolved allowing the magnesium to be consumed within the reaction.

decided to do my experiment on chicken livers. It was interesting to do this experiment on chicken livers. The results were that since there is DNA I needed to stir the ingredients slowly and do the experiment as quickly as I can due to the fact that there are enzyme in the cells. I found out that liquid detergent is an active agent which the detergent destroy the cell membrane and also the protein. Abstract I chose to do my experiment on chicken livers to see what the results would be. The

Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom

Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing
