The endocrine system is one of the major systems in the body, it is one of the two systems established for regulating the body to achieve homeostasis. This system plays a role in long distance intercellular communication, coordination, and homeostasis control (Rice University-Open Stax, 2016). It is made up of a collection of glands which produce hormones, regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, mood, in addition to a plethora of other…

Research Question This lab will be driven by the research question, do changes in temperature (4oC, 25oC, 37oC, 50oC and 70oC) have an effect on the reaction rate of enzyme amylase and starch? Hypothesis As the temperature increases, the enzyme will have a quicker reaction time with the starch, therefore when met with the iodine, no change will occur in the colour of the solution, showing that the starch is now absent. The enzyme amylase and starch solution in 4oC and 25oC will change the colour…

GENTAMICIN The drug selected for study is Gentamicin. Gentamicin is an aminoglycoside antibiotic composed of a mixture of related Gentamicin components and fractions and is used to treat many types of bacterial infections, particularly those caused by Gram-negative organisms. Isolation and Preliminary studies 2 demonstrated that it is a mixture of basic, water soluble antibiotic containing the aminocyclitol 2-deoxystreptamine and two additional amino sugars. Chromatographic separation of…

Clostridium perfringens is typically found in soil and if this is eaten or coming in contact with the animal it can cause variety of diseases, especially in domestic animals. These diseases include different enteric syndromes such as bovine and ovine enterotoxemia, fowl necrotic enteritis, and lamb dysentery. Strains of most toxin types like alpha and beta toxin have been involved in necrotic enteritis beta toxin is caused by type-C strains. The pulpy kidney disease is caused by type-D strains…

Biopharmaceuticals: GMOs and Vaccines Clarifying the definition, history, methods and relevancy of GMOs to our society is of the utmost importance. Genetically modified organisms and their applicability in multiple arenas have been a source for debate around the globe. Many individuals believe GMOs to be unsafe and unethical, while the biotechnology sector sees a profitable life-saving technology. Through the evaluation of scientifically relevant articles regarding genetically modified…

Fragile X syndrome (FXS) is identified as the leading monogenic cause of autism and congenital mental retardation. It is estimated that the frequency of FXS is 1/7000 males and 1/11,000 women (Hunter et al., 2014). In Australia, since one child is born with Fragile X every week, around 1 in 3600 boys and in 4000 – 6000 girls suffers this syndrome with the higher severity in boys. Position of the causative gene for FXS named fragile X mental retardation gene 1 (FMR1) was found at the diagnostic…

Introduction: Forensic science is the application of various scientific techniques and methods to investigate the physical Crime evidence. Forensic science links the Suspect, victim to crime scene, and link victim to suspect and suspect to victim. To determine the relevance of the evidence, number of different techniques are being used. This evidence is than presented in court of law in order to determine the innocence or guilt of a suspect. Different type of cases are encountered like rape,…

The relationship between central dogma and a genetic code The vital sequence of different processes that transfers the genetic code from DNA via mRNA to finally form the functional product (finished proteins) together forms the central dogma of modern molecular biology. Thus, the genetic code is the basis of the central dogma of molecular biology. Central dogma is nothing but the flow of genetic information in all living cells including human cells from DNA to RNA to proteins. The central dogma…

project this semester was to improve the Cresyl Violet (CV) staining protocol used in the laboratory. Cresyl Violet is a dye used to stain brain tissues and it is commonly used in histological sectioning. The dye is basic and therefore it binds to ribosomes that are RNA rich and nuclei of cells, which are acidic. Also, the dye leaves a purple color on the stained neuronal tissues. For the purpose of most of our studies, Cresyl Violet staining is used to analyze the lesion size and location in…
