Essays on Rbcs

Overview: Overview: Antigen-antibody reactions are commonly used in immunological assays. In a traditional agglutination assay, the end product is a visible antibody-antigen complex that settles as visible particulate matter in the solution. In other cases, the reaction is invisible and wants the use of a specific enzyme or isotopic probes that can amplify the signal created by the antigen-antibody reaction, so that they can be detected with the naked eye or an ELISA/RIA reader1. Hemagglutination is a visible antigen -antibody assay in which soluble antibodies react with antigen on the surface of (red blood cell) RBC to form a ...

Introduction

The human body consists various cells that are actively involved in the maintenance of metabolism. Although, the body organs, cells as well as tissues usually carry out different functions, the body cells are similar in regard to their pertinent metabolic needs (Sherwood, 2015). Thus, maintaining the internal environment at a constant state mainly by proving the oxygen as well as nutrients and elimination of waste in the body is an essential process for the wellbeing of the cells as well as the whole body. As such, the various processes through which the human controls or regulates the internal environment ...

Dr. Victor Babes and discovery of Babesiosis

Babesiosis also known as piroplasmosis is a tick- borne disease, which is an emerging intra- erythrocytic parasitic infection in human. The parasite first known to affect only cattle but later was found in other mammals as well. The parasite was later found to affect humans as well. The severity of the disease caused by this parasite can range from mild- to moderate- to severe, i.e., causing death by organ failure. Till date approximately 100 species of the Babesia genus has been identified yet only a few has been suggested to be pathogenic in humans. The symptoms more or less ...

Introduction

Pernicious anemia refers to a health condition that is associated with a deficiency in vitamin B12 due to its poor absorption in the intestines whereby this results to a reduction in the RBCs (red blood cells). Typically, the condition occurs as a result of inadequate production of IF (Intrinsic Factor) in the stomach whereby this leads to poor absorption of vitamin B12 (Bizzaro & Antico, 2014). Among the main symptoms associated with the disease include; fatigue, diarrhea, breathing difficulties, pale skin as well as tingling and numbness in the feet and hands. In reference to the case study, it is ...

Body Fluids

Some parameters of urine “macroscopic” examination are quantity, color, clarity and cloudiness. Some of the constituents that might be observed in a urine “microscopic” examination are epithelial cells, crystals, bacteria or yeast and protozoan casts. Three conditions that can occur prior to a specimen being poured into a centrifuge tube that can produce false-negative microscopic results are the use of an old, unpreserved specimen, failure to mix the specimen and an amorphous precipitation. For the overall evaluation of the sediment and the detection and quantity of casts, the magnification that should be used is 100x. On the other hand ...

Chapter #16:

Question 1. Insect-eating birds will decrease in number since their source of food has been reduced. The birds may also migrate to warmer areas during this period.

Question 2.

The habitat is the specific place where the organism lives e.g. a fish’s habitat is water. On the other hand, niche is the position and the role played by the organism in an ecosystem. It includes how the organism obtain food and shelter, the mode of survival, and the mode of reproduction (Sutton & Anderson, 2009, p. 46). For instance, a lion’s niche in the ecosystem is that of a predator.Question ...

Introduction and Overview

The Rhesus factor (Rh) refers to the red blood cell’s(RBC) surface antigen;the name Rhesus comes from the small Indian monkeys in which it was first discovered. Rh incompatibility,sometimes referred to as Rh disease, is a condition that occurs when a woman with the Rh-negative blood type is exposed to Rh- positive blood cells, leading to the development of Rh antibodies. This condition can have fatal outcomes including haemolytic disease of the foetus or newborn, autoimmune haemolytic anaemia and haemolytic transfusion reactions (HTRs). These conditions have, in the past, raised a lot of concerns, and some ...
