Haemophilia A

Gene therapy is an experimental form of treatment that modify the expression of an individual’s genes or correct abnormal genes by replacing a faulty disease-causing gene with a working version, or by introducing a new gene to cure a condition or modify its effects. For example, diseases such as cystic fibrosis, muscular dystrophy, hemophilia, and many cancers result from the presence of defective genes. Gene transfer first appeared in 1960s. The first therapeutic use of gene transfer was…

medicine declined, this refers to the infected blood that was being distributed in hospitals to treat patients that suffered from haemophilia. In North America during the 1980s,the failure of the system could not distribute uncontaminated blood products because they believed the economic cost would be thigh. Due to the failure of the system, anybody who suffered from Haemophilia regardless of their status,class, gender or race would suffer the repercussions. The inequality experienced in this…

1a. Reasons for the development of the technology The amniocentesis procedure was developed to assess the unborn baby and whether it has any risk of developing or has already developed a serious health condition or abnormality, however, its first use was to determine the sex of the baby. The test is taken when risk factors are present including: - Being aged over 35 - History of inherited problems in the family - Other tests have shown the baby may have problems During an amniocentesis, a needle…

gene defects in unborn children, meaning that in the future we may be able to prevent genetic disorders such as Down Syndrome and Cystic Fibrosis. Whether this is ethical, however, is still in debate. There are many hereditary diseases, such as Haemophilia A, Cystic Fibrosis and Down Syndrome that are the result of genetic disorders and mutations. Although these disorders are extremely rare, usually affecting one person in every several thousands or millions as they are typically recessive, they…

This article deals with gene therapy related issues. According to authors, gene therapy may substitute a defective gene sequence with its perfect version and thus, can cure severe diseases. The article is mainly focused on the progress and dilemmas of gene therapy in context of hemorrhagic disorders like Hemophilia. Authors also talk about those approaches, which are linked, with gene therapy’s clinical applications (Murphy & High, 2008). The article attracted me as it is relevant with use of…

Genetics and Evolution Gene Therapy What is Gene Therapy? ‘Therapeutic gene therapy’ is an experimental technique that uses genes to treat or prevent disease. Inheriting faulty genes causes a wide range of conditions, including cystic fibrosis and haemophilia, and may cause susceptibility to some cancers. It is an experimental technique with aims to rid genetic conditions at their source. Several approaches are being tested - - Replacement of a mutated gene with a working one - Deactivating a…

had already been damaged by a number of factors that could be held responsible for the overall downfall of Tsar Nicholas II. One of these factors is the influence that Rasputin, a monk who convinced the Tsarina that he could cure her son of his haemophilia. Rasputin’s influence over the royal family made him widely hated, especially by the aristocracy. Other short term factors include the discontent amongst the Russian people due to the Tsarinas leadership during the First World War, this…

receive a blood transfusion while they loses blood excessively, they are very likely to die in a short period of time. It is very common for patients that suffers from liver or kidney disease, infections, anaemia, or maybe a bleeding disorder such as haemophilia to receive a blood transfusion. Medical and health care workers will find the best blood component transfusion for each situation they think is the most suitable. For example, a platelet transfusion is needed when the patient is at risk…
