INTRODUCTION:. Orthodontic treatment are potentially unstable although a number of factors can be cited as influencing long term-result. It called relapse orthodontics. Relapse Orthodontic is the return, following correction, any change from the final tooth position at the end of treatment relapse, could be a return to the original teeth position, caused by periodontal,occlusal,soft tissue factor and growth. Orthodontic relapse is a complex problem. 1,2 Studies have shown that stability and…

the chances of cardiac fatigue that is usually prevalent in those that do not exercise (Fleg & Strait, 2012). Some of the associated cardiac pathologies identified and prevented through exercise are oxidative stress, cardiac fatigue, cardiomyocyte apoptosis, and accumulation of heat shock proteins (Gielen et al., 2010).…

insulin this hormone helps maintain homeostasis in the blood glucose. Since diabetes T1 is an autoimmune disease the body will destroy these insulin-secreting cells, as it believes that these cells are not part of the body, this process is called cell apoptosis (programed cell death). At this point there is rally no given reason why the body takes the beta cells as a foreign object, but scientist are doing everything they can to find the cure for diabetes. As we now know diabetes is an auto…

Epstein - Barr virus or, Human herpesvirus 4, is the virus that causes infectious mononucleosis, and contains double-stranded DNA. This virus is species specific in that it only infects humans. The Epstein-Barr virus was discovered in 1964 when Michael Anthony Epstein and Yvonne Barr found it in a Burkitt lymphoma cell line. In 1968, they then linked the virus to the disease infectious mononucleosis. Once the host is infected with the virus it stays in the host for the remainder of the host’s…

A cancer cell could affect all parts of the body. A cancer cell can and will grow and divide with positive and negative growth factors and unfixable DNA damage, where a normal cell would go through apoptosis, or cell suicide. A normal cell with positive growth factors will grow and divide, and with negative growth factors they will not grow and divide, where cancer cells will grow and divide with positive and negative growth factors. A cancer cell is…

Restriction enzymes are used to manipulate DNA sequences to create recombinant DNA by first cutting up the foreign DNA in order to protect the bacteria cell against invading DNA from other organisms. The enzyme is very specific when it comes to identifying a specific DNA sequence. When the enzyme identifies the specific DNA sequence it cuts both DNA strands at specific points at the restriction site. Lastly, the DNA ligase joins the DNA from two different sources and produces a recombinant DNA…

Clinical Question 2 – Genetics, Oncology Limit your answer to no more than 3 pages, not including references. I will only read your first 3 pages. A 54 yo woman is diagnosed with malignant melanoma on the posterior neck. The lesion has a horizontal spread of roughly 12 mm although borders are quite irregular. She undergoes surgical resection with wide, grossly clear margins. Pathology report suggests features consistent with an ulcerated lentigo maligna melanoma to a depth of 4 mm. • Describe…

An increasing body of experimental evidence suggests that lung/kidney interactions are involved both in AKI-associated acute lung injury (ALI) and renal consequences of acute respiratory failure. Positive pressure ventilation, changes in PaCO2 and PaO2 levels along with systemic inflammation participate in the renal response to acute respiratory failure. Positive pressure ventilation may modify venous return, cardiac after-load and may decrease cardiac output along with decreased renal blood…

through its basal surface. These cells endure biochemical changes and transform into mesenchymal phenotypes (Kalluri and Weinberg, 1997). This transformation imparts increased migratory potential, invasiveness and renders the cells resistant to apoptosis. The completion of EMT is involved in disruption of basement membrane through which these mesenchymal cells migrate to underlying tissues (Kalluri and Weinberg, 1997). A second event involves a localized increase in tumor size and induction of…

human is pretty clear. Indeed, the homologous protein is a mRNA-binding protein that takes part in translation elongation (3). It also plays an important role in the cell progression, mRNA decay and the maintenance of cell integrity. It regulates apoptosis, plays an important role…
