Alpha-1 Antitrypsin Deficiency Alpha-1 Antitrypsin Deficiency also known as A1AD or AAT Deficiency is a genetic disorder. Laurell and Erickson in Sweden reported the first patients with the condition in 1963. Since their discovery much has been learned about the history if A1AD (Liebrman, 2002). The name of the disease comes from a deficiency of the serum antiprotease. This enzyme is a protein that protects the lungs from germs, dust, pollution, smoke and other inhaled chemicals. This enzyme…

Clubfoot or Congenital talipes equinovarus (CTEV) is one of the most commonl congenital pediatric foot deformity with an incidence of 1 in 1000 live births [1, 2]. equinus at ankle, hindfoot varus, forefoot adduction, and midfoot cavus are the four components [3–6]. Historically, Hippocrates,introduced conservative management in around 400 BC [10, 11]. Later, Kite introduced a method [12] in 1993, which included manipulation and casting technique, but the success rate was poor [7, 8, 13].…

due to heredity or environmental factors, but rather the results of random errors. About 66 percent of cancers were due to random mistakes, 29 percent were due to environmental factors or people’s lifestyles, and 5 percent (5%) due to inherited mutations [2] The transcription of a gene begins with transcription elements, mostly protein and RNAs, binding to regulatory sites on DNA. The frequency of this binding affects the level of expression. Experiments have verified that a stronger binding…

and form. Why a doctor? The answer was simple, I longed to be the person who could make a difference in not only an ailing individual, but to the world of medicine. I hoped to aid in finding cures to the worlds most complex of diseases and genetic mutations. I was certain that only doctors had the power to do this, as they were the liaison between a patient and their illness. In fact, it wasn’t until I was given the opportunity to join The Walker Lab did I come to realize that my previous…

Genetic editing is a process where DNA is inserted, replaced, or removed from a genome using artificially engineered nucleus’s, or molecular scissors. Gene editing can be used to treat diseases and to modify aspects of an organism , but there are some disadvantages to genetic editing. There is also some question to the danger and ethicalness of genetic editing done to embryos. Genetic editing in the past has cured diseases like severe combined immune deficiency , leukemia and leber's…

Chromosomes, or strings of genes carrying genetic information, are vital to the existence of living things. A specimen cannot have more or less than how many that particular species needs. In humans, this number is 23. The 23rd pair of chromosomes, referred to as Group X, contain the sex cells that decide the gender of the organism. If a Y chromosome is present, the organism is male, and if not, it is a female. If the chromosomes fail to separate correctly during meiosis (type of cell division…

What did cancer look like in the mid 1800’s http://www.cancer.org/acs/groups/cid/documents/webcontent/002048-pdf.pdf In 1838 german pathologist Johannes Muller showed cancer is made up of cells rather than lymph. Muller showed that cancer cells developed from budding elements (blastema) between normal tissues Rudolph Virchow suggested that cells including cancer cells are derived from other cells. He bliebed that cancer spread like liquid in the 1860s german surgeon karl theirch showed that…

particular area of the body but forms in muscles, tendons ligaments, and other connective tissue. This fatal disease, in essence, traps “the body in a prison of bone” (Massey). FOP is a very rare and unusual genetic disease and is “caused by the mutation of a gene in the bone morphogenetic protein” (WebMD).…

abnormality. Sometimes physicians are not able to label a disease, because it is unknown, and so they call it an undiagnosed disorder. These disorders vary from all sorts of genetic genes from your siblings. Genetic disorders can be caused by a mutation by one gene, multiple genes, or by the combinations of gene and environmental factors. Some disorders are inherited by a parent or are present at birth, but as mentioned previously, sometimes these disorders are not caused by inheritance but by…

1. Polycystic kidney disease: Polycystic kidney diseases (PKD) are a group of developmental renal disorders that are characterized by progressive fluid accumulation in dilated renal tubules to form cysts, generating kidney enlargement, numerous large cysts compromise the function of the remaining normal tubules and eventually lead to renal failure as well as various external manifestations. It is associated with several genetic and non-genetic disorders, but the most common causes of…
