Question 1: Pathophysiology of Mr. Jensen’s post-operative hypovolemia

Hypovolemia is a surgical condition that indicates the rapid fluid loss that may result in organ failures. The outcomes of the hypovolemia are mostly due to insufficient circulating volume or scarce perfusion. Often hypovolemia is secondary to hemorrhage the reason of which includes severe internal or external blood loss and GI, thoracic and abdominal bleeding maladies (Devitt, 2001). Hypovolemia involves significant fluid loss other than blood that can be further accompanied by refractory gastroenteritis and widespread burns. Hypovolemia may develop in post-surgical incidence, bone fracture, due to ...

How absentee fathers affect teen pregnancy in daughters

Introduction The family is the basic unit of society. From this structure, individuals learn the tenets of how to integrate into society and cope with other members. Most mammal species live in the family unit, be it nuclear or extended. Within the family, members learn to bond, share and assist each other with difficulties. The human species shows the most sophisticated form of human organization. When children get born, they only get taught how to survive as adults, but there are certain values that parents must pass on to their children. Each family and society have different values and ...

Increased erythropoietin production Increased heart rate Increased cardiac output Enhancement in oxygen extraction The answer for this question is b. increased heart rate. A reduction in tissue oxygenation as happens in anemia stimulates increased production of erythropoietin through a complex feedback mechanism. Increased production of erythropoietin enhances erythropoiesis in anemia. Increased extraction of oxygen in anemia is a compensatory mechanism that is mediated by an increase in 2, 3-diphosphoglycerate concentrations. Increased cardiac output is the main hemodynamic compensatory mechanism in anemia that aims to increase blood flow to the body organs. An increase in heart rate ...

The diagnosis of the disease is based on the presence of clinical features as well as the use of specific laboratory tests. Diagnosis is not ...

Introduction

Nutritional needs changes throughout a person’s life that if not properly assessed may lead to malnutrition. Malnutrition is the state of the body lacking important nutrients or having excess or imbalance of energy. According to studies, 16% of people over 65 years and 2% of people over 85 years are malnourished. Studies also show that approximately two-thirds of people occupying hospital beds are above the age of 65 years (Ahmed & Haboubi, 2010). Malnutrition is associated with a number of health outcomes such as poor wound healing, slow recovery from surgery, higher hospital readmissions, and deaths. Malnutrition is high ...

Introduction

In recent decades, trends in diets tailored to promote weight loss have resulted in a significant increase in the intake of protein, particular in people with overweight and obesity issues. Accordingly, researchers have questioned the benefits or risks linked to the habitual consumption of “dietary protein in excess of recommended intakes” (Martin et al., 2005). In general, the primary concern has involved the possibility that diets rich in protein may increase hyperfiltration and, hence, exacerbate renal damage. Nevertheless, the potential link between protein-rich diets and renal damage has also been questioned due to an absence of adequate clinical evidence. ...

As athletes, physicians, sports professionals, and the general public continue to search for the most effective diet for nutrition and physical development, high protein diets have emerged as a viable alternative for many people. However, there are disagreements about how to define a “high protein diet” (Tipton). Touted for many years, the Atkins Diet initially allows no calories from carbohydrates and moves into a maintenance regimen of only meat and vegetables (Westman, Phinney and Volek). The Paleo Diet has emerged as a similar recommendation of organ meats, fruits, vegetables, and nuts while excluding grains, sugar, dairy, and legumes (Tarantino, ...

Type 2 diabetes is featured by the conflation of insulin resistance and inappropriate insulin secretion. The levels of free fatty acids increase the plasma contribution to the insulin resistance which, in turn, decreases the transportation of glucose to the muscle cells and enhances the breakdown of the fat. The pathophysiology of the disease is debated on account of the role of insulin sensitivity and beta-cell functioning. Additionally, the specific roles played by these factors are still unclear. Nonetheless, there is considerable agreement that both these factors are crucial to explaining the disease's pathophysiology. Diabetes Type II typically exists when ...

Enzymatic Activity Blood Glucose Regulation and Enzymatic Activity Blood glucose levels in the human blood need to be balanced; as otherwise, it would lead to several fatal consequences and ill physical health. Uncontrolled blood glucose levels may damage blood vessels which supply blood to important organs such as the heart, kidneys, lungs, brain etc. Homeostasis in blood glucose levels is maintained by the coordinated efforts of two vital hormones – insulin and glucagon, along with action by certain enzymes. All these work together, to maintain homeostasis in the body according to body needs. Insulin is secreted by the β-cells of ...

Absorption

Absorption is the process through which biomolecules traverse through the GI tract into the circulatory system. Digested food gets absorbed in the small intestinal lumen through four processes, which include active transport, passive transport, endocytosis and facilitative diffusion. The efficiency of absorption of nutrients may be attributed to the large surface area lined up with hair like projections and microvilli cells .

Rat Endocrinology

Hypothalamus 1. What is the molecular mechanism to release TRH? TRH refers to the thyrotropin-releasing hormone. This hormone is produced by the hypothalamus. Before the full activity of TRH, some tightly controlled processes occur in the body including the appropriate folding of prohormone to move to the secretary pathway, the processing after translation, and movement of the peptides, which are processed, towards the secretary granules for secretion (Nillni n.p.). TRH develops from bigger inactive precursor (known as proTRH) as a result of modifications after translation and moved through the controlled secretary pathway. Prohormone convertases (abbreviated as PCs) including PC1/3 ...

CF is a disease that affects many organs including the upper and lower respiratory tracts, pancreas, intestines and reproductive system. Over the past 20 years, our understanding of the manifestation and management of the disease has progressed dramatically. CF was once considered a condition of childhood and there was very little expectation that children would enter adult life. However, CF has become a multisystem adult disease with the increased survival attributable to advancements in standardized treatment, introduction of ...

Abstract

This paper discusses how exercise stimulates the release of growth hormone. Older people tend to have lower levels of the hormone. As a result, mechanisms have been formulated to help deal with the deficiency which includes inducing the growth hormone into the individual’s body. This, therefore, leads to the discussion of the exact mechanism through which the growth hormone facilitates exercise, maintains growth and repair of worn out muscles or even reverses the aging process among the aged. Also, the functions of IGF-I binding proteins during exercise and its importance in aiding the release of the GH is ...

This work seeks to summarize the article,” The Expanded Biology of Serotonin” authored by Berger, Gray, and Roth. According to authors, serotonin, a neurotransmitter that modulates neural activity and neuropsychological processes, is widely used in psychiatry and neurology. It is located mostly outside the central nervous system, and the 15 receptors of serotonin are found outside as well as inside the brain. It regulates a number of biological processes including, bowel motility, cardiovascular function, bladder control, and ejaculatory latency. However, they mention that serotonin regulates some other processes as well including platelet accumulation through receptor independent, but transglutaminase-dependent covalent ...

Abstract

Growth hormone is one of the many hormones released in the human body. This paper discusses the relationship between the growth hormone and exercise. The exact mechanism through which the growth hormone facilitates exercise is discussed in the paper. It is noted that the growth hormone is released rapidly in young children and teenagers but the production slows down with age. Other factors such as gender, adipose and diet also play a huge role in regulating the release of the growth hormone. For that reason, it is recommended that the aged people should exercise more frequently to induce the ...

The human body consists of trillions of cells that work together synchronously for the maintenance of an organism. The metabolic needs of all the cells in the body are almost similar. For the well-being of a human body and the proper functioning of all the cells, constant internal environment needs to be maintained by providing the cells with oxygen and nutrients (Homeostasis and Regulation in the Human Body < OpenCurriculum, 2016) The internal environment of the body is tissue fluid, which bathes all cells making up the body (Mader, 2016). The composition of the tissue fluid must always remain ...

Immunogenic cell death: the role of SAGE

Immunogenic cell death: the role of SAGE

Introduction

Millions of cells are always being removed in the human body not only to regulate and coordinate the body’s biochemical pathways but also to keep the cells healthy. This particular systematic removal of cells occurs through a selective mechanism called cell death or apoptosis process. Apoptosis is not a new concept in the understanding of the biological workings of the body. This homeostatic death of body cells has been defined as a tolerogenic or a non-immunogenic event for many [1]. However, new discoveries have unearthed the existence of a different concept ...

I. UNDERSTANDING THE DISEASE AND PATHOPHYSIOLOGY 1. How is acid produced and controlled within the gastrointestinal tract? The production of acid occurs in the stomach by cells that are therein. The cells found in the stomach produce intrinsic factors and hydrochloric acid. There are chemical messengers that help during the activity. They are histamine, gastrin and acetylcholine. Gastrin helps in stimulating the cells to produce secretions when food enters the stomach. An enzyme somatostatin inhibits the secretions when needed. The digestion takes place in three phases; the cephalic phase, gastric phase and the intestinal phase. It is in the ...

General features of melatonin

Melatonin is a hormone, which is thought to play an important role in daily processes of humans’ lives, being secreted by the pineal gland, which is an endocrine gland, located in the middle of the brain. After its discovery the first function (which later gave the name to this hormone) was the ability of this hormone to lighten one’s skin color. This experiment was conducted on frogs, however even nowadays everybody knows that our sunbathing results in suntan due to activity of melatonin. This is a so-called skin-darkening effect of melatonin. First discoveries of this hormone were done ...

Inadequate insulin secretion leads to a rise in blood glucose levels, which is the main characteristics of diabetes. By the time a diagnosis of type 2 diabetes (T2D) is made, 70 to 80% of beta cell mass loss is already done. Loss of beta cells of pancreas occurs gradually, beginning much before the diagnosis of diabetes is made and continuing even after that. For this reason, the damage becomes irreversible (Cnop, 2005).

Introduction

Type 2 diabetes mellitus is distinguished by insulin resistance and a relative disorder in insulin secretion. The production and development of the disease is not completely understood and we find genetic factors as well as environmental factors affecting the insulin release. The disease is increasingly common and basically caused due to obesity and sedentary lifestyle. The chronic metabolic disorder affects both the insulin secretion and insulin action. It is the suppressed hepatic glucose production as well as lower insulin-mediated glucose uptake by the muscles that contribute equally to postprandial hyperglycemia.

Question a

Diabetes mellitus (also type 2 diabetes) is a medical condition affecting the body’s use and conversion of energy. It may arise from various biological malfunctions such as over-secretion of glucagon hormone, insufficient secretion of insulin and resistance to regulation of glucose levels by insulin hormone. The condition may arise either from poor diets or from the effect of hereditary and environmental factors. Excessive consumption of high calorific foods, minimal exercising and obesity are some of the predisposing factors that may make one susceptible to the disease. This is especially so when these factors supplement genetic factors. The main risk ...

Human behavior is determined by the interplay of several factors; individual genes and the environment are some of the leading factors in determining personal traits and tendencies. However, although inheritance and the environment play the greater role in determining an individual’s behavior, hormones as well as neurotransmitters also play crucial roles in shaping one’s behavior. Some hormones, for example, are linked with controlling anger and aggression in both men and women, while other sets of hormones are linked with the control of sleep. Hormonal imbalances are also linked with the control of individual temperaments. Hormones exert their ...

Revealing both the best and worst aspects of humanity, the Renaissance was characterized by extraordinary human achievements, a heightened interest in human potential and, paradoxically, by superstition, witch-hunting, exorcism and torture. The humanism of Renaissance had four main themes: the belief in the individual’s potential, a tendency to view religion as being more personal rather than institutionalized, an increased interest in the classics, a rejection of Aristotelian philosophy in order to develop a more scientific attitude. As the ecclesiastical power started to deteriorate, the pressure of having to fit scientific inquiry with Christian dogma decreased, making inquiry steadily more objective. Copernicus ...

Introduction

Allergy is an immune system disorder. Allergy or allergic reaction is a hypersensitivity to otherwise innocuous substances present in the environment. The allergic reaction is usually a rapid response; however, the sensitivity to certain allergens can be acquired over a period. It was previously called the type one hypersensitivity. It is characterized by an over activation of leucocytes, called the mast cells and the basophils following activation of immunoglobulin E (IgE) (Frigas, Gleich 1986). This activation of the basophiles and mast cells triggers an inflammatory response.

Pathophysiology of the allergic response

The type 1 hypersensitivity reaction is initiated when an allergen is introduced to the atopic individual, ...

The Process of Spermatogenesis in the Male Testis

Spermatogenesis is an intricate process that involves mitotic cell division, meiosis, and its process. The regulation of spermatogenesis involves the endocrine and the paracrine mechanisms. The spermatogenesis endocrine stimulation involves the follicle stimulating hormones (FSH) and the luteinizing hormone. The luteinizing hormone acts through the intermediary testosterone that is produced by the leydig cells in the testis. A male fertility requires the production by the testis with large number of normal spermatozoa by spermatogenesis process. There are three major steps subdivided in the process; the mitosis, meiosis, and the transformation of the round spermatid. The multiplication of spermatogonia is ...

Prior to the discovery of insulin, diabetes was dreaded as a disease leading to death. It was known that a rise in the sugar level in the body worsened the condition of diabetic individuals and that the sole treatment of diabetes known to people was to restrict the dietary intake of sugars (‘’The discovery of insulin”, n.d., para. 1). During the nineteenth century, examination of patients who succumbed to diabetes revealed that the pancreas was damaged. In 1869, Paul Langerhans discovered that a group of cells called beta cells, whose function was unidentified, existed within the pancreatic tissue and were eventually ...
