Sickle cell anaemia describes a hereditary autosomal recessive disorder that affects a protein found in red blood cells (erythrocytes) called haemoglobin. Erythrocytes contain about 280 million haemoglobin molecules that are composed of globulin protein and a heme molecule that binds to iron. Haemoglobin allows respiration of oxygen and exchange of carbon dioxide in blood, essential for all body systems. This disorder, determined at contraception, results in 100% of blood cells becoming sickle…

Jenkins Lesley Willoughby Gripped in controversy, the United States of America had grappled with whether or not to study embryonic stem cells and clone human tissues since they were discovered. Stem cells, according to the National Institutes of Health, are unspecialized cells with remarkable potential for developing into a variety of organic structures (Stem Cell Basics: Introduction). These biological components were first discovered in human umbilical cord blood in 1978, and in 1981, they…

Stem cell research has persisted for decades, and has doubtless produced numerous positive and influential results, namely the replacement and repair of vital organs and tissues in the human body. Indeed, adult stem cell therapy has proceeded largely undisputed in medical procedure. However, embryonic stem cell research, the extraction of stem cells from early stage embryos, has been highly controversial and polarizing. Mainly, ethical concerns have arisen in response to the very concept and…

Legalization of stem cell research Cells are the building blocks of all living organisms. Human bodies contain billions of different types of cells including skin cells, muscle cells, bone cells, and brain cells. Most of the cells in the human body are specialized and designed to perform specific functions within s particular part of the body. Once human cells die, they are irreplaceable and too much death of cells causes damage of their origin body part. However, certain cells of the body…

Overview Stem cell therapies are not new; Doctors have been treating patients with bone marrow stem cell transplants since the 1970s. The controversy raised about 20 years ago when they learned how to remove stem cells from human embryos 1 Moral claims made concerning embryonic stem cells research relates to human rights, medical benefits, policies and laws, and religion’s opinion. Research councils support the stem cell research because of its great values and benefits from the expected…

conditions that stem cells could help benefit. This issue affects them because without the answer and option of stem cell research, they can’t help or provide their patients with an answer. Doctors influenced my viewpoint because they are the ones doing good for their patients, while also doing no harm to their patients…

According to “Essentials of Pathophysiology” by Carol Porth, “sickle cell disease is an inherited disorder in which abnormal hemoglobin (hemoglobin S [HbS]) leads to chronic hemolytic anemia, pain, and organ failure”. The recessive gene is inherited and appears as the sickle cell trait if heterozygous or sickle cell disease if homozygous with two HbS genes. The amount of hemoglobin that is affected by the gene depends on if they are heterozygous or homozygous, and therefore affects the gravity…

Stem cells is an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, it can copy themselves for an unlimited period of time, also have the potential to develop into different types of cell. Each new cell will become another type of cell with a more specialized function when the stem cell divides, these cells such as the red blood cell, muscle cell and the brain cell. Overall on some main functions of the stem cell, the…

Stellate Cells (SC) are morphologically characterized by dendrites that radiate from the main cell body leading to a star-like shape and giving rise to the name Stellate i.e. star-like. They can be found in various parts of the body such as: kidneys, lungs, liver, breast, and pancreas; some of these ones have been less thoroughly characterized compared to others such as hepatic SC [1-5]. Although the dissimilar microenvironment of SC in different parts of the body condition them to react…

How Media Influences the Portrayal of Stem Cell Research Swikriti Dasgupta INTRODUCTION Link to Media and Stem Cells: Facebook. Twitter. Myspace. YouTube. Fox. BBC. NBC. Snapchat, Instagram etc. If you did not post a photo of the food you ate, did you actually eat it? If you did not check in the place you visited, did you actually go there? If you think about it, we are live at all times on social media. Everybody knows what we are doing, where we are going, what we are eating, and what we…
