Types of Tissue Engineering As known by now, Tissue Engineering is the combination of the cell, engineering material and suitable biochemistry factors that are used to improve the biological functions. There are 4 types of Tissue Engineering, mainly which are Autograft, Isograft, Allograft and lastly Xenograft. Firstly, autograft is said to be a graft from one area to another area of the same individual, such as in the transplantation of normal skin from one area to another burned area of the same
“Love interrupts at every hour at the most serious occupations, and sometimes perplexes for a while even the greatest minds.” – Schopenhauer1 All of us that have been in love can identify with this quote, but the real question is how do we find, and choose our lovers? Schopenhauer would argue that making a decision, about an ultimate lover is merely biological. He believes in something he calls the will to life which he defines as “an inherent drive within human beings to stay alive and reproduce
William went to school on a hot sweltering summer day. Sweat dripped down his forehead. When he got to school he stuffed his lunch inside his suffocating locker. He didn’t know that the hot temperature was causing his food to become rotten over the past few hours. When it was time for lunch William grabbed his lunch and entered the cafeteria. Meanwhile, inside his body… “ Yesss!! They’re not getting in!!! Woohoo!!” shouted Commander Immune. Team Food Poisoning was aggravated that they couldn’t get
peripheral blood mononuclear cells (PBMC). These blood cells are an important element in the immune system to fight infection and adapt to intruders. PBMCs can be extracted and cultured in vitro from patients with cancer. Immune cells identify major histocompatibility complex (MHC) present on infected cell surfaces, generating cytokine release and eventually causing apoptosis. However, CIK cells have the ability to detect infected or malignant cells in the absence of antibodies and MHC, allowing for a quick
Yearly, around six hundred to nine hundred people are diagnosed with Aplastic Anemia within the United States. Aplastic Anemia is a autoimmune hematological disorder that causes pancytopenia which is a reduction in major blood components, namely, erythrocytes, leukocytes and platelets. This disease has been labelled as a type of bone marrow failure, that is often due to not one but a variety of disorders that occur simultaneously. Aplastic Anemia can therefore be defined as a bone marrow disorder
After graduation, I will pursue a Ph.D. in chemical biology or cell biology, as well as a career as a research professor. My research interests include the major histocompatibility complex (MHC), a structure in cell membranes that our immune system uses to discern our own cells from those of pathogens; and antimicrobial peptides (AMPs), short chains of amino acids with bactericidal properties. Research into these fields
cells. The interaction occurring between a cell that would possess a molecule of HLA in contact with an antigenic peptide and T lymphocyte, with a receptor present, would demonstrate a process where the recognition of HLA and the peptide forming a complex, would result in the instigation of activation and proliferation of T lymphocytes where this immune response, underlies almost all immune response.

Tuberculosis (TB) is a transmittable and often severe airborne disease, an infection caused by a bacteria known as Mycobacterium tuberculosis (Mtb). TB usually affects the lungs, but it also can affect any other organ of the body. It is usually treatable with a scheduled routine of medicine taken for 6 months to 2 years, the length of treatment is conditional on the type and severity of the infection ( WHO. October 2015). This usually happens when a person breathes in the contaminated air, in which
interaction is near impossible. From telephone calls to advertising billboards, communication is ubiquitous. Communication essentially refers to the generation and receiving of messages across a variety of contexts, channels, media, and cultures. This complex interaction is composed of both verbal and non-verbal interactions. Verbal language is defined as the use of sounds and language to communicate a message and thus accents, dialects, and languages all fall under this “verbal code.” Its counterpart
These are the 3 most important facts about how cells tell each other apart and know what to attack and what not to. First, Allorecognition is a very research active subject. Allorecognition is immune cells using a system called major histocompatibility complex (MHC) to know which cells belong to the body and which are foreign. Brain cell,skin cells and nearly all our other cell in our body have (MHC) proteins on their outer surfaces.
Can a person fall in love with a kiss? Kissing is an expression of affection. Scientists have a theory of how kissing became a universal behavior. The theory is that humans have a strong attachment towards kissing beginning with breastfeeding or bottle feeding. According to scientists, this causes babies to feel comfort and have a positive emotion associated with kissing. Associating this positive emotion to kissing creates a pleasurable feeling for two individuals who are attracted to one another
involved in these pathways (Dunkelberger, 2010). The classical pathway is induced when the protein C1 interacts with a complex antibody/antigen. The alternative pathway is induced when the protein C3 interacts with some bacterial components. The MBL pathway is induced when the Mannose Binding Protein interacts with some bacterial elements. The three pathways induced the membrane-attack complex (figure
Inside our body is an unceasing battle, warding off dangerous invaders. The immune system in our body protects us from dangerous bacteria and harmful viruses. But is there more to the immune system and can we the use immune system for treatment? Right now, immunotherapy, the use of the immune system to fight cancer cell, is growing worldwide. It is highly effective than other methods of cancer treatment such as chemotherapy and could save future generation from cancer. There are several different
Face Transplants; Ethics and Technology Over the past century there has been a considerable improvement in medicinal technology that allows for many life-saving and cosmetic procedures to be undertaken. Face transplants are one such improvement that permit recipients to have a second chance at a relatively normal life. This form of transplantation is used as treatment for victims with severe injuries of the face such as extreme burns that have robbed them of many normal facial features including
Review the mechanisms by which endothelial cells contribute to inflammation in key diseases The endothelium is a cell layer that is lined on the interior surface of lymphatic vessels and blood vessels, which are made up of endothelial cells (Dorland, 2012). The endothelial cells in direct contact with blood cells are called vascular endothelial cells while those in contact with lymph are called lymphatic endothelial cells. Besides regulating hemostasis, endothelial cells also possess important functions
more likely to have children than females who mate with the same male twice." (Judson, 2002, p. 52). In other words, mating with more than one partner secures reproduction. Along with the ideology of having multiple partners, Judson talked about major
Today, if you ever needed a new lung, heart, liver, or any organ at all, you’d have to wait…..a long time. Fortunately, a new process in the field of Tissue Engineering called Bioprinting aims to fix that. Bioprinting is exactly what it sounds like – printing out biological materials from a printer. Of course, the actual process is much more complicated than just hitting print on a computer and waiting for an organ to pop out like a piece of paper. It starts with a modified inkjet printer and ink
Multiple Sclerosis (MS) is “a chronic, degenerative, progressive disease of the central nervous system characterized by the occurrence of small patches of demyelination in the brain and spinal cord” (Smeltzer & Bare, 1996). Over 2 million people are diagnosed with MS and it is known that there is a link between geography and the diagnosis of this disease (Faguy, 2016). In personal interviews with the patient and his wife, discussions were held about the disease process for this patient; medications
Pemphigus Vulgaris: A Closer Look Pemphigus vulgaris is a serious but rare autoimmune disorder of the epithelial cells and mucosal lining of the skin. The first cases were recorded by McBride in 1771 and by Whichman in 1979. McBride was to describe the first to casualties as being caused by “bloody ichor” and “putrid ulcers”. (Jordon, 2013) However, Whichman was the one who would originally name the disease as pemphigus. The word “pemphigus” is of Greek origin which means blister or bubble. (Jordon
with a protein and is deposited in the liver, spleen and kidneys, but the beryllium when bound with a biological protein, a hapten, can result in the chronic form of the disease which is believed to be a delayed hypersensitivity immune response. The major toxicological effects of beryllium are on the respiratory tract,specifically the lungs and their alveoli. Beryllium and its unique characteristic led to it being used widely in a variety of industries prior to is know toxic effects. Today it is
