("Pertussis."). Two different solid cultures that are used in growing B. pertussis are Bordet-Gengou agar (BGA) and Regan-Lowe agar (RLA). Bordet- Gengou agar contains potato starch and is peptone free‚ also an inhibitory substance. It also contains glycerol as a stabilizer‚ and an antibiotic‚ such as penicillin‚ to restrain gram positive organisms from growing‚ although the antibiotic may slightly

Nutritional science investigates the metabolic and physiological responses of the body to diet. With advances in the fields of molecular biology‚ biochemistry‚ nutritional immunology‚ molecular medicine and genetics‚ the study of nutrition is increasingly concerned with metabolism and metabolic pathways: the sequences of biochemical steps through which substances in living things change from one form to another. Carnivore and herbivore diets are contrasting‚ with basic nitrogen and carbon proportions

Analysis: Lab 1 Identifying Carbohydrates There were many ranges of color changes in the Benedicts test and Iodine stain. For the Benedicts test‚ this oxidation/reduction response changes the arrangement of the reducing sugar creating a colored precipitate. The change in color is correlated to the first concentration of the reducing sugar. For the iodine test‚ the three dimensional structure of various polysaccharides permits them to react with the iodine stain to produce a certain color. As far

Every skin type becomes vulnerable to lower temperature‚ but those with dry skin are especially susceptible to these concerns. According to cosmetic doctor Dr. Jules Nabet of the Omniya MediClinic in Knightsbridge‚ London‚ the humidity level drops in colder temperatures‚ and the resulting dry air leaves the skin extremely dry.

The small intestine (or small bowel) is the part of the gastrointestinal tract following the stomach and followed by the large intestine‚ and is where much of the digestion and absorption of food takes place. It receives bile juice and pancreatic juice through heptopancreatic duct‚ controlled by Spincter of oddi. Ininvertebrates such as worms‚ the terms "gastrointestinal tract" and "large intestine" are often used to describe the entire intestine. This article is primarily about the human gut‚ though

Problem Set 1 1. Explain lipoprotein physiology and metabolism (Chapter 15). - Lipoproteins are a biochemical formation that aid with the transporting of lipids. The four major pathways include Lipid absorption pathway‚ exogenous pathway‚ endogenous pathway and reverse cholesterol transport pathway. All of these pathways are dependent on a particular particle know as apo-B that contains lipoproteins which‚ functions as a transport for dietary and Hepatic lipids to the outer layers of the cells

DESCRIPTIVE WORDS FOR WINE Wine tasting‚ as a production control technique‚ depends upon converting into words the impression created by the reaction of the wine on the taster ’s palate. In order that one wine‚ tasted by several individuals‚ be reported in the same way by each‚ it is necessary that all of the tasters use the same words for the separate palate impressions the wine creates. The terms used in sensory examination fall naturally under the four headings of appearance‚ color‚ taste

Petroleum jelly‚ petrolatum‚ white petrolatum or soft paraffin‚[1] CAS number 8009-03-8‚ is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25)‚[2] originally promoted as a topical ointment for its healing properties. Its folkloric medicinal value as a "cure-all" has since been limited by better scientific understanding of appropriate and inappropriate uses (see uses below). However‚ it is recognized by the U.S. Food and Drug Administration (FDA) as an approved over-the-counter
