According to the research done in the Literature Review, acidosis is usually caused by a buildup of lactic acid in the body due to muscle exertion. In comparison to the average pH of the distilled water, the average pH of the lactic acid solution decreased

Metabolic engineered of biocatalyst: A solution for PLA based problems ABSTRACT Poly lactic acid(PLA) is a biodegradable polymer used in many biomedical as well as in packaging Applications. Conventionally, PLA is produced by two method which is direct condensation of lactic acid and ring opening polymerization. The polymer produced from these conventional methods produced polymer which have low molecular weight. Conventional methods of PLA production requires catalyst which makes it unfit for

Mechanisms of DOM There are many theories that have been researched in order to explain why an individual experiences DOMS. Theories include but are not limited to: enzyme efflux, lactate formation, muscle spasm, connective tissue damage, muscle damage and inflammation (Cleak, Gulick). Researchers suggest that not one single theory can be directly correlated to the effects of DOMS. The unique sequence of events from all possible modules contributes to the effects that an individual might experience

Glucansucrase is an enzyme from Streptococcus mutans which is essential for the pathogenicity shown by it in dental caries. Glucansucrase converts sucrose molecules to glucose molecules and uses it for production of the biofilm chain. Thus the inhibition of this enzyme can prevent the long chain formation and in turn prevent biofilm formation typical in dental caries. (Ito K. et al, 2011) [54]. A variety of -glucans polysaccharides such as dextran, mutan, alternan and reuteran are synthesized by

Physical Activity Log Assignment Name Institution Physical Activity Log Assignment 1. Introduction – Describe the significance of monitoring physical activity, setting goals, and evaluating results. It is always important to set goals and to monitor them. These activities help people to have a productive and fruitful lifestyle. Monitoring and evaluation are examples of self-management (Health.gov, 2014). Self-management and self-monitoring is the process of understanding and looking at one’s

Penalty taking and Game theory Penalty shootout is a method used in order to find out who is the winner after a soccer match that is drawn. The team who scores the most goals after 5 attempts is the winner. The goal is defended by the goalkeeper of the opposite team and it represents one of the most difficulties tasks a goalkeeper can face. Game theory is a theory “that deals with strategies for maximising gains and minimising losses within prescribed constraints” (http://dictionary.reference.com/browse/game+theory)

Positive Thinking William Channing once said, “Difficulties are meant to rouse, not discourage. The human spirit is to grow strong by conflict.” In the “Diary of Anne Frank”, Anne is going through hiding from german police and meanwhile, is stuck with her family and anothers. While in “”Dear Miss Breed” by Joanne Oppenheim, Louise Ogawa is writing about her tough times during the war. They both are able to stay positive which proves that having a positive attitude it the best way to respond to conflict

Wadhawan et al. (2015) suggested that Pica is likely to cause effect on teeth. Chewing on stones and bricks can lead to attrition of teeth. Damage to teeth and gingiva occurs due to chewing from abrasive materials such as twigs or metals. On reviewing literature, many cases reporting ill effects of pica on dentition have been published. An unusual case report was reported by Djemal et al. (1998, case report on tooth wear associated with an unusual habit). Handiso (2015) suggests the prevalence of

it causes water vapour to condense forming small water droplets. We breathe in oxygen and some nitrogen which is essential for life. We exhale carbon dioxide that can be tested for limewater because carbon dioxide dissolves in water to form carbonic acid (H2 C03). Glucose is a reactant of respiration. The glucose in your blood comes from carbohydrates in your food. Carbohydrates include sugar and starchy foods like: bread, pasta and rice. Keywords: Carbon dioxide, Glucose, Water, Oxygen and energy

treatment to stop smoking, Noninvasive positive-pressure ventilation (called CPAP) or a breathing machine and some Bronchodilator drugs to reserve airway obstruction. Compensation refers to the body 's natural mechanisms of counteracting a primary acid-base disorder in an attempt to maintain homeostasis. In Respiratory Acidosis, the elevation in PCO2 result from a reduction in alveolar ventilation. Elevation in PCO2 is never due to an increase in CO2 production. Acute VS Chronic places a role in

An article by Siggard-Anderson (2005) explains that “acid-base balance refers to the balance between input (intake and production) and output (elimination) of hydrogen ion” (p.4). The maintenance of acid-base balance during exercise is vital to performance. This is because exercise decreases muscle and blood pH. When exercising a build-up of lactic acid can occur in the muscles which when coupled with an increase in carbon dioxide will lower your body’s pH balance. In order for the human body to

dioxide comes from the lungs during exhalation. Carbonic acid is a weak acid and is therefore in equilibrium with bicarbonate in solution. When sig- nificant amounts of both carbonic acid and bicarbonate are present, a buffer is formed, because they neutralize each other.) Under normal circumstances, there’s much more bicarbonate present than car- bonic acid (the ratio is about 20:1). Metabolism produces more acids than bases. It produces acids (even in a balanced body), but the alkaline blood is able

Standard Preparation: 100 mg of standard ascorbic acid was weighed precisely and transferred to a 100 ml volumetric flask, added 70 ml of 0.5% sodium metabisulphite and dissolved by shaking. The volume was made up to the mark with 0.5% sodium metabisulphite for getting a concentration of 1 mg/ml. 2 ml of this solution was taken into another 100 ml volumetric flask and made the volume up to the mark with 0.5% sodium metabisulphite which resulted in concentration of 0.02 mg/ml. The solution was filtered

Albumin-bound formulations Abraxane was the first albumin-bound chemotherapeutic agent to get FDA approval. It contained PTX (a taxane) non-covalently bound to nano-albumin (nab), and was prepared by homogenization of PTX in association with human serum albumin. Multiple PTX molecules (hydrophobic in nature) were bound to each nab. Preclinical studies (in rats) showed equivalent efficacy and improved safety when compared with Taxol (PTX formulation in Cremophor solvent). Clinical trials of Abraxane

titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due

waters (Environment Canada 2012). Through a dual oxidation process, Nitrate is formed in a reaction of Nitrogen with Ammonium ion producing fertilizer and manure. The oxidation state of a nitrate compound is 1- . Nitrate is the conjugate base of nitric acid (HNO3), a strong

role of stomach acid Chapter 14 section 1 Noopur Rajendra Grade – 11AA 25/04/2016 Ms. Sara Kassem Sharjah American International School Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produces. Abstract Hydrochloric acid, which is also called HCl, is a highly corrosive acid. It is a strong

oxygen in extreme cases it could cause death. It could react with other chemicals causing more sickness. If you consume nitrate then you could just get small stomach flu, but when pregnant, or a baby it could cause much worse because your stomach acids are different.

The aim of the investigation was to determine the effect of pH on the rate at which catalase decomposes hydrogen peroxide and consequently answer the researchable question “How does pH influence cells and consequently an organism”. The hypothesis, “As the pH deviates from 7 the initial rate of oxygen production will decrease” is supported by the results. The trend displayed in Figure 3 is, as the pH deviates from 7 the initial rate of reaction decreases. Figure 3 shows that the rate of reaction (%O2/s)

The temperature of the water was then recorded to the nearest 0.1⁰C. Then the melting points of phenylacetic acid, o-anisic acid, and benzilic acid were determined by the use of a Mel-Temp. The unknown sample was obtained from the chemical stockroom. A small scale of crystals from unknown was placed in a test tube with the following solvents: cyclohexane, hexane, toluene, diethyl
