2.5. ANTIOXIDANT STATUS 2.5.1. TLC - Semi Quantitative DPPH Assay 0.2 % DPPH solution in methanol was prepared and kept in the fridge for further use. The grid space was marked with 1.0 cm2 space on an aluminum based TLC sheet (Merck silica gel 60F254) and a stock solution of all the extracts together with the standard were prepared in methanol. A series of dilutions of the stock together with the standard were prepared ranging from 400 µL to 0.01µL for the last dilution. The grid on the TLC…

I look around the battlefield looking uneasy. In every direction, I catch a glimpse of death. Death is everywhere. Death is laying next to me waiting for my time to come. Death is next to my fallen comrade slowly taking his soul away with every subsequent second. I am terrified to think that my time can come any second. War has been much worst than I could have ever imagined.The visibility on the battlefield is close to none. Dirt, gunpowder, blood, and ammunition flying in the air. When my ears…

Factory farming, also known as industrial farming, is a modern form of farming where livestock such as cattle, pigs, or chickens are kept in tight cages known as battery cages to meet the food consumption of human. Factory farms keep large numbers of animals to be raised for food in tight and confined spaces in order to minimize operation cost. The meat that comes from these factories are cheaper because there is enough food to meet demand. Over 99% of the meat in America comes from a factory…

Antibiotics How do you feel about antibiotics? Are they helpful or are they harmful, are they safe or are they dangerous? The current situation we are dealing with right now is should everyone have access to antibiotics in their homes. Today as of 2016 “antibiotics are life-saving drugs” (Dryden, M) but can be harmful if we don’t use them correctly. “Everyone prescribing antibiotics should consider both their clinical and public health responsibilities” (Dryden, M) because antibiotics…

“The brain is important in the human body because it allows a person to think, feel and store memories, and it controls and coordinates the body’s actions and reactions,” states the Atlanta Brain and Spine Care. Because of the great importance of the brain, our body has many different parts and way of working to protect it against any harm or damage. The protective membranes that surround the brain and spinal cord are called the meninges. The meninges consist of three layers, the dura mater,…

Crisis. Whether you are an organization who is new to the industry, or a well-established brand, no company is immune crisis situations. Events of this nature if not managed correctly, have the ability to bring even the most impervious seeming companies to their knees. Chipotle’s ineffective communications’ response during their 2015 E. coli crisis, has had detrimental repercussions to the brand’s public image. The focus of my paper will assess two months in this yearlong crisis, specifically…

Enterobacter spp. Enterobacter spp are part of the enterobacteriaceae family. They are facultative anaerobic gram negative bacilli. Their means of motility is by means of petrichous flagella. They produce acid upon glucose fermentation and are methyl red negative, voges-proskauer positive. Optimal growth temperature is 30*C .80% are encapsulated. E. spp have been associated with nosocomial outbreak and are opportunistic pathogens. They can cause numerous infections such as cerebral abscess,…

Francisella tularensis is an important microbial agent which causes the severe infection of tularemia. The intracellular life cycle of this bacterium is supported by a vast range of protective guards such as enzymes. Although several enzymes are recognized in different subspecies of the bacterium, acid phosphatase and superoxide dismutase are seen in all bacterial subspecies. On the other hand, the most important enzymatic system relating to host cells is NADPH oxidase. For this reason, the…

In microorganisms metal resistance character is regulated by genes which are organized in operons. Commonly, the heavy metal resistance genes are found on plasmid carried by metal resistant bacteria. In the presence of specific metals in the vicinity of bacterial niche the heavy metal resistance genes are expressed and induced. The regulation of expression of metal resistant gene is specific for each heavy metal and is dependent upon metal species concentration. The promoter and regulator genes…

Shadowing Experience and Reflection Over Thanksgiving break, I had the opportunity to shadow Mrs. Karen Feldmeyer at Atrium Medical Center in Middletown Ohio. During my four-hour visit, I experienced aspects of nutrition in a multitude of different settings including the psychiatric wing, the intensive care unit, and a physical therapy panel. Each of these opportunities provided me with a different perspective on the importance of nutrition, and how nutrition impacts a patient’s recovery process…
