Calorimetry

A mathematical model was proposed describing the quantitative relationships between sugar, water and protein on the gelatinization of wheat starch following the heating in microwave for 20s as determined by differential scanning calorimetry. Sugar addition decreased the degree of gelatinization of starch due to the microwave heating. Sugar was found more effective in delaying gelatinization than the water and protein. In water-limited systems the effects of sugar and protein on the…

We will be looking specifically at the total calories and protein in relation to wound prevention and healing. Carbohydrates and fat are also essential in diet, but the biggest nutrition contributors to wound management are the total calories and protein. Micronutrients such as supplemental vitamins and minerals may be beneficial as well. We will also discuss these. Calories provide our bodies with energy during the hyper-metabolic and catabolic state which the body is in when a wound is…

10.1 SUMMARY The aim of the present investigation was to formulate Raloxifene Hydrochloride Liquisolid compacts, with coadministration of a bioenhancer, for oral bioavailability enhancement. The reason for poor bioavailability (2%) of Raloxifene Hydrochloride is low solubility (100μg/mL) and high hepatic first pass metabolism. According to BCS, Raloxifene Hydrochloride is considered as Class II drug, lipophilic and highly permeable compound. Therefore, formulating Liquisolid Compacts bearing…

Calorimetry is performed with a calorimeter. You can use to foam cups to insulate better or use a calorimeter. A calorimeter is a device used to measure the amount of heat involved in a chemical or physical process. For example, when an exothermic reaction…

"What are the energy requirements for this specific patient?" this is a frequently asked question of dieticians and doctors in the clinical setting. Resting energy expenditure (REE) is the largest component (~65-75%) of the total energy expenditure, which differs per individual [1, 2]. Variation of REE in individuals of the same age, sex and weight is related to body composition. Individuals with a higher fat-free mass (FFM) will have a higher REE [3]. Children and adolescents differ in…

The development of new drug discovery technologies like high throughput screening, combinatorial chemistry, etc. has led to the discovery of a large number drugs that are poorly water soluble.(1,2) Approximately 40% of the NCEs are poorly water soluble and has poor bioavailability.(3) The successful clinical use of these molecules requires the application of solubility enhancement based formulation approaches. Among the various solubility enhancement technique like use of cosolvents,…

body which results in energy expenditure. There are several numbers of techniques for the assessment of physical activity related energy expend, the most valid technique to estimate this value at the definition of the physical activity is indirect calorimetry (Westerterp, 2013). Oxygen consumed during postexercise recovery period and during exercise above resting level contribute to calorie expenditure. The physiology of upperbody exercise and lower body exercise has been thoroughly researched…

On February 6 of 2018, at 11:00 a.m. in room 1043 of Thomas Cole Research building, Sade Rhodes spoke about the characterization of lignin-coated cellulose nanocrystals (C-CNCs) as a reinforcing agent in polypropylene (PP) nanocomposites. The logistics of the seminar that was most enjoyable was when the speaker focused on the matter of Nanocelluloses. She provided a lot of information on this topic and I understand how it related to her topics in her research. However, the only part that I did…

following analysis will be performed to determine if there was any change in the polymorphic form of the drug or to characterise and provide structure information of the physical state of the dipyridamole. X-ray diffractometry, differential scanning calorimetry and infrared…
