Multiple Choice Questions

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 ...

Introduction

According to Huether (2012), venous insufficiency is a medical condition characterized by the inability of the veins of the lower extremities to effectively push blood back to the inferior vena cava. The venous blood evades its normal antegrade flow path and refluxes down the veins in the lower segments resulting to lower limb venous congestion. Syndromes in this condition are mostly due to valvular incompetence common in the low pressure superficial venous system, although they may also be due to incompetence of the valves in the deep venous systems.

Pathophysiology of CVI

The failure of the valves of superficial veins is attributed to ...

Introduction

In the opening of the story, Hemmingway begins with a short pitch epigraph, an observation of a lone dried leopard carcass that sought the tip of Mount Kilimanjaro, which the Maasai call "Ngaje Ngai," meaning the House of God (Hemingway, 2004).

Having been involved in several cases, Daniel Groll’s intention to provide a lasting solution to this problem intensified. His intentions are to develop a model for understanding disagreements in a clinical setting. Groll at providing insight into what doctors can and cannot plausibly be said to know regarding what’s best for their patients. Groll deals with this by developing taxonomy of clinical disagreements. Groll’s secondary aim is to show that Robert M. Veatch’s theory on what on what clinicians can and cannot about their patients’ well-being is overly skeptical and limits the role. In the article, Groll presents a ...

“Lady Lazarus”

“Lady Lazarus” is a free verse poem comprising of 25 three line stanzas. This poem is a companion piece to “Daddy,” another of Plath’s most famous poems. Within “Lady Lazarus,” a strange tension exists between the solemn subject matter and the deceptively light tone and form of the piece. The language and rhythm are both of a conversational style, which are in direct contrast with the violence depicted in the words. A good example of this is in the ninth and tenth stanzas: “What a million filaments. / The peanut-crunching crowd / Shoves in to see / Them unwrap me hand and foot ...

Objectives/Aims

1) The aim of the experiment was to scrutinize food samples for the presence of microorganisms using the Australian Standard (AS) techniques to establish quality and safety of food produce for consumption. 2) The experiment is also aimed at comparing standard and new techniques of food sampling. This will assist in establishing the most efficient, convenient, cheap, reliable, sensitive and easy to use technique in analyzing food samples for the presence of microbial organisms.

Introduction

Microbial organisms in food can either be useful or poisonous if consumed. For years now, microorganisms have been used in the ...
