Pasteurization is a process that involves heating of raw milk to a certain temperature within a given set of time. This process kills harmful bacteria found in unpasteurized milk, for example, Salmonella, Listeria and E coli responsible for food borne illnesses. These bacterial organisms are responsible for human diseases such as Typhoid, diphtheria, Listeriosis and tuberculosis. The process was first initiated by Louis Pasteur in the year 1864. Pasteurized milk can stay for a certain period without refrigeration. However, refrigeration especially after opening the seal, is still necessary because of some nonpathogenic bacteria that because food spoilage and is non-receptive for heating. ...

Digestion occurs in the gastrointestinal system, which is composed of the gastrointestinal tract (GI tract) and the associated accessory organs.The process of digestion occurs through six steps, namely ingestion, secretion, mixing,digestion, absorption and defecation. (Tortora&Derrickson, 2008).

Anatomy of the digestive system

The GI tract or the alimentary canal is a long winding tube that measures approximately 30 feet (9 meters) in length. The mouth, esophagus, pharynx, stomach, small intestine, large intestine and the anus make up the GI tract.The salivary glands, tongue, teeth, gallbladder, pancreas and the liver make up the associated accessory organs (Tortora&Derrickson, 2008).

Abstract

Human XPA is a protein engaged in DNA damage recognition and repair. A mutation in the gene encoding the protein causes an autosomal recessive disorder, xeroderma pigmentosum (XP), which renders an individual sensitive to sunlight and causes skin cancer. XPA is a 273 amino acid protein, which is predominantly localized in the nucleus. It is expressed at both high and moderate levels in several tissues. The protein serves as a damage sensor in a nucleotide excision repair mechanism, through which the damage to a DNA strand is verified and repaired by formation of a newly synthesized strand. Besides this primary NER mechanism, XPA in conjunction ...

Harvey requires enough energy to perform. Consequently, he must consume enough calories to meet all his energy needs. The actual requirement for calorie intake depends on one’s level of fitness and bodyweight. In addition, the intensity, frequency, and duration of physical activity also greatly influence one’s actual energy requirement.

Carbohydrates

Given that Harvey’s daily workouts involve high-intensity activities, his calorie intake should comprise of between55 to 70 percent carbohydrates. In this case, 3 grams per pound of body weight would be appropriate. Based on this recommendation, Harvey should consume approximately 480 grams of carbohydrates per day in ...

Introduction

Cells are independent units of life. However, when a cell becomes part of an organism, it becomes part of a tissue and organ system. Cells in a tissue are joined to each other and to the extracellular matrix (ECM) by cell junctions. There are three kinds of cell junctions: Occluding junctions, anchoring junctions and communication junctions. Occluding junctions occur in the epithelium where the adjacent cells are so tightly sealed together that even small molecules cannot pass. Communicating junctions allow the exchange of chemical and electrical signals between cells. Anchoring junctions are the ones which attach a cell either to its neighbor or ...

Abstract

Adequate nutrition is required for optimal wound healing. The normal processes that allow the progress of wound healing are disrupted due to nutritional deficiencies. Increased infection rates and decreased wound tensile strength are associated with malnutrition. Chronic on-healing wounds are formed in malnourished patients or individuals. Such patients can develop infections, pressure ulcers, and delayed wound healing. Morbidity and mortality among malnourished patients with chronic wounds constitute a serious clinical concern. Wound healing is considered as a complex process. It is the process of replacing injured tissue with new tissue (produced by the body). Production of new tissue is associated with ...

Hemoglobinopathies: Analytic Diagnostic Techniques

Hemoglobinopathies and Thalassemia’s are a kind of Genetic disorders caused mainly by a mutation or deletion of Globin genes in Hemoglobin. Hemoglobin consist of α or β Amino acid chains. An alteration in α chain production leads to α Thalassemia and alteration in β chain causes β Thalassemia. Hemoglobinopathies on the other hand may be caused due to the structural abnormalities or alteration of amino acid sequences in the Globin genes. These are mainly hereditary and constitute to around 4 to 5% of the world population. (WHO Statistics, 2012) Each year around 250,000 to 300,000 new born children have either hemoglobinopathies or thalassemia. Both ...

For decades researcher and nutritionists have been advocating low-fat and low-cholesterol diet. This approach has been touted as a preferred way of losing weight and a way of preventing or controlling heart and other chronic diseases. As a consequence food companies tailored their products to be low in fat, and substituted them with salt, sugar or refined grains to make up for flavor or texture . However, this theory is being given a fresh look. In the 1960s, fats and carbohydrates provide 45% of calories to the Americans adults, and still only 13% of them were obese. Today while Americans eat less fat, yet ...

Background

Early scientists and nutritionists believed that the most vital nutrient in living organisms, for building and maintaining the body was the protein. The role of proteins as enzymes came into existence several years later. This was around 1926 when experiments showed that enzymes were proteins. Insulin was the first protein to be sequenced. Hemoglobin was the first structure of proteins to be resolved. Myoglobin was then resolved later.

X-ray diffraction analysis (X-ray crystallography) led to the determination of the structure of the proteins (three-dimensional structure). The purification of proteins can be made possible from cellular compounds. Several methods have ...

ABSTRACT

Muscular dystrophy disorders are hereditary neuromuscular disorders in which the skeletal muscles deteriorate progressively due to loss of the functional protein dystrophin encoded by the DMD gene. There are many types of muscular dystrophy and they are classified based on the genetic mechanisms involved. Muscular dystrophy symptoms are usually caused by mutations in the link between cytoskeletal and basal lamina proteins since dystrophin is a sarcolemmal membrane protein (Meregalli M, 2013). Loss of ambulation is also an important clinical milestone in the clinical diagnosis of muscular dystrophy. Respiratory muscles, particularly the intercostal and diaphragm muscles are also affected by muscular ...

Abstract

Bones are formed through a process known as osteogenesis from three different lineages. This process takes place through two different methods, which are intramembranous ossification and endochondral ossification. A large increment in bone mass takes place in childhood, as well as puberty, through the formation of endochondral bone. At this point, growth hormones are known to play a role. This paper will focus on the process of cartilage and bone formation and the stimulation of bone formation by the growth hormone. There are a number of factors that regulate the formation of bone, while growth hormone affects a number of factors related to ...

Embryonic stem cell is a crucial factor in the developmental process of a multicellular organism. Embryonic stem cells (ESCs) are derived at early stages during development and eventually give rise to all type of tissues and organs in an animal. The ES cell lines have three properties consisting of self-renewal, primary chimera formation and pluripotency [1]. Pluripotency, a key feature of ESCs, refers to the capacity of a cell to differentiate into several different types of tissues [2]. An array of cellular factors play important role in maintaining pluripotency and determining cell fate in the developmental pathway. Negative effects on these factors may ...

Abstract

The current antiretroviral drugs have been efficient in the management of HIV by suppressing the virus's replication. It has, therefore, helped in changing this virus from a deathly disease to a chronic infection. The utilization of extremely active antiretroviral therapy (HAART) calls for a lifetime prescription to prevent viral rebound by reducing the viral load to undetectable low levels. This high maintenance of treatment and the various side effects of the drugs and non-HIV related morbidity have led to the need for a better form of therapy. There has been an extensive study on stem cell manipulation done to develop gene therapy ...

Poliomyelitis vs. Guillain-Barré syndrome: A comparative analysis of etiology, symptoms, prognosis and treatment Both poliomyelitis and Guillain-Barré syndrome (GBS) cause acute flaccid paralysis (Yuki & Hartung, 2012). However, polio has been nearly eradicated, worldwide, making GBS a leading cause of acute flaccid paralysis (Yuki & Hartung, 2012). Poliomyelitis and GBS are comparable with regard to some of the symptoms exhibited by the patients (Papadakis & McPheee, 2013); however, both of these diseases differ remarkably in the causative agent, pathophysiology, prognosis and treatment regime (Papadakis & McPheee, 2013).
