...?Alexander Cuevas McDonald Advanced Research Writing 8 April Use of Tranexamic acid: Literature Review Tranexamic acid is a common hemostat used to arrest bleeding either during or after surgery and in other medical conditions that lead to blood loss. Tranexamic acid competitively inhibits the activation of plasminogen to plasmin thus preventing plasmin from degrading fibrin. This synthetic antifibrinolytic agent is derived from amino acid lysine. This paper examines various print and online literatures that provide information on the use of tranexamic acid. Literature on the use of tranexamic acid in orthopedic surgery and other...

...Lab Partner: Lab Meeting Time: Acid base and redox titration of vitamin C Introduction:This report seeks to determine the amount of vitamin C in a tablet. Using both redox reaction between vitamin C extract and iodine solution, and vitamin C extract and sodium hydroxide solution, the experiment will carry out titration reactions and apply stoichiometry concepts to determine the percentage of vitamin C in a tablet. The experiment will apply the concept of molality and stoichiometry to determine the number of moles and mass of vitamin C. Molarity is the concentration of solute particles in a solution. Measured in moles per unit volume, it shows the concentration in terms of the reacting units rather that...

...? Acid-Base Case Study Angelique Harris Grand Canyon Advanced Pathophysiology and Pharmacology for Nurse Educators NUR-641E April 18, Acid-Base Case Study The acid base disturbance in this patient is caused by a condition known as metabolic alkalosis. Consequently, this state occurs when the PH of the blood in arteries rise above 7.45 which is the maximum PH. The pH above 7.5 is termed as alkalemic. A general decline in hydrogen ion concentration or a surplus of base leads to alkalosis. Considering the case study, the pathophysiology of metabolic alkalosis is common and generally occurs when bicarbonate is increased. This...

...-base imbalances in the body (Story, 2001). Different agents do exist to reversibly bind the ions of hydrogen and impede the pH change. The extracellular buffer involves agents such as ammonia and bicarbonate. The phosphate and proteins play the role of intracellular buffers. The patient’s body began compensating the disturbances in the acid base. This was done when the patient’s pressure started to be laboured and his blood testing showed increased elevation of creatine phosphokinase amounts of cardiac muscles. This showed a bicarbonate system of buffering which is normally the key since carbon dioxide was shifted by carbonic...

...?Application of Pearson’s hard and soft acid/base theory in bioinorganic chemistry Introduction: Pearson’s hard and soft acids and bases theory is a concept that explains reactions mechanisms and the stability of compounds. It designates an element or compound as being ‘hard’, ‘soft’ or borderline depending on the polarizability and charge condition. Soft elements and ligands are highly polarizable and have small charge states. Hard elements and ligands are weakly polarized and have higher charge states (Jolly). Borderline elements and ligands have polarizabilities and charge states that are intermediate to hard and soft elements and ligands. The theory implies that soft...

...? Acid base titration Aim The experiment intended to ascertain concentrations of Dilute Hydrochloric acid and Dilute Sulphuric Acid solutions by conducting Acid-Base titrations. Hypothesis Phenolphthalein change of color from pink/purple to colorless signified a transformation of the solution’s nature from being basic to acidic, which was the reaction’s endpoint or neutrality point. This is because in acidic, basic conditions phenolphthalein indicator usually indicates colorless and pink/purple colors respectively. Background theory Acid – base titration is one of the most essential Titrimetric analysis techniques commonly used in wet analysis to determine quantities or concentrations of the reacting reagents (Patnaik, 2010, p. 57... , hence...

...Buffer and Buffer Capa Experiment Introduction A buffer is a chemical solution used to maintain and prevent rapid changes that might occur to pH in solutions. Similarly, a buffer is a mixture of molecules releasing or binding H+ so as to maintain a moderately stable pH. The function of a buffer is to minimize the change in pH whenever acid or base is added to a solution. There are several types of buffers and each particular buffer only stabilizes the pH of a solution within a particular range. One buffer might be operative within a range of pH 2 to pH 6, whereas another...

...Buffer Overflow & Rootkits al Affiliation Buffer Overflow & Rootkits Computer systems are vulnerable to attacks by a variety of on the internet. Most people’s computers become the victims of these attacks because of the lack of enquired protection. The reason is the lack of awareness of the existence of protective programs that might avert these attacks. Other individuals are just ignorant that such attacks even take place in the first place and, therefore, see no reason to install protective software (Ben-shalom, Naystut & Muttik, 2015). Perhaps, this is due to the nature of some attacks to integrate themselves well into the computer’s operating system. Another reason is the failure of individuals to...
