the job are taking drugs. Drug testing analysis’s any biological specimen, it includes blood, hair, urine, or any other bodily fluids to learn if drugs are present or not. Major applications of drug testing include detection of the presence of performance enhancing steroids in sport, employers screening for drugs banned by law such as cannabis, cocaine and heroin and police officers testing for the presence and concentration of alcohol ethanol in the -blood commonly referred to as BAC blood…

There are many methods for measuring GA [33], including immunoassay-related techniques (such as enzyme linked immunosorbent assays) [17, 34], boronate affinity chromatography[17, 35], high-performance liquid chromatography (HPLC)…

strong enabling them to produce a lot amount of saliva improving the quality of the nest and lowered the impurities level. As we can see, the expensive and high quality nest is EBN that are harvested from the first period. On the second period, the season are quite dry making the food supply to reduced and affect the…

Andrew Wittman Biology 152 Lab Section 409 3/23/2015 PURIFICATION OF SPERM WHALE APOMYOGLOBIN AND THE ORIGIN OF ITS HELICAL FOLD Abstract The purpose of this research is to understand how secondary structures of a protein, in this case sperm whale apomyoglobin, affect the denatured state of that protein. The scientific community has been working under the impression that once denatured by urea, a protein loses all of its secondary structure. In this research the effect that apomyoglobin’s…

(Clark, HIGH PERFORMANCE LIQUID CHROMATOGRAPHY - HPLC, 2007). Samples are loaded into an agarose gel slab, which is placed into a chamber filled with a conductive buffer solution. A direct current is passed between wire electrodes at each end of the chamber. Since most molecules…

My overarching research interests focuses on delineating animal 's metabolic responses to nutrition interventions or health conditions, associated with the animal performance and quality of its derived products. I use a combination of modern analytical chemistry (liquid/gas chromatography and mass spectrometry) and bioinformatics (univariate and multivariate statistical analysis) to measure metabolites in biological samples to provide insights on physiological or pathological status and…

Sickle cell disease is a major health burden in the Indian community. It contributes to millions of deaths worldwide however it is most prevalent in tribal populations in the rural sectors of India. “Sickle cell disease or SCD is an inherited abnormality of the red blood cell characterized by chronic haemolytic anemia with numerous clinical consequences” (Ugwu 87). The shape of hemoglobin, which gives red blood cells their color is turned from an oval to a crescent shape when the sickle cell…
