It is not clear exactly why the knee joint is relatively immune to the patho- mechanics that affect the hip and foot; however, because the muscles pri- marily control motion in a single plane, there is less opportunity to create severely maldirected force vectors. Most of the stability of the knee is due to its inherent ligamentous stability, the strength of which is usually able to overcome the weak abnormal muscle forces in varus, valgus, or torsional malalignment planes. The high stress on the extensor side of the joint may lead to patella alta and stress reactions in the patella. Stiff knee and crouch gait patterns are most defined by the position of the knee; however, most of the etiology of these problems emanates from the foot. Ankle equinus was the first CP deformity that received significant atten- tion.
Only monozygotic twins will have identical patterns order 100mg kamagra soft with visa erectile dysfunction forum. Bioinformatics can be defined as the gathering purchase 100mg kamagra soft otc zinc causes erectile dysfunction, processing, data A recently introduced technique will permit the screening of many genes to deter- storage, data analysis, information extrac- mine which alleles of these genes are present in samples obtained from patients. The surface of a small chip is dotted with thousands of pieces of single-stranded Bioinformatics also provides the scientist DNA, each representing a different gene or segment of a gene. The chip is then with the capability of organizing vast incubated with a sample of a patient’s DNA, and the pattern of hybridization is amounts of data in a manageable form that allows easy access and retrieval of data. The results of the hybridization analysis could be Powerful computers are required to perform used, for example, to determine which one of the many known mutations for a par- these analyses. As an example of an experi- ticular genetic disease is the specific defect underlying a patient’s problem. An indi- ment requiring these tools, suppose you vidual’s gene chip also may be used to determine which alleles of drug-metaboliz- want to compare the effects of two different ing enzymes are present and, therefore, the likelihood of that individual having an immunosuppressant drugs on gene expres- adverse reaction to a particular drug. Lymphocytes would be Another use for a DNA chip is to determine which genes are being expressed. If treated with either nothing (the control) or the mRNA from a tissue specimen is used to produce a cDNA by reverse transcrip- with the drugs (experimental samples). RNA tase, the cDNA will hybridize with only those genes being expressed in that tissue. The treatment then could be more specifically analog. The cDNA produced from your tailored to the individual patient. This technique also can be used to identify the three samples would be used as probes for genes required for tissue specificity (e.

USE OF RECOMBINANT DNA TECHNIQUES FOR THE can group genes showing similar levels of PREVENTION AND TREATMENT OF DISEASE stimulation or inhibition in the presence of the drugs and compare the two drugs with A. Vaccines respect to which genes have activated or inhibited expression. Before the advent of recombinant DNA technology, vaccines were made exclu- sively from infectious agents that had been either killed or attenuated (altered so that they can no longer multiply in an inoculated individual). Both types of vaccines were potentially dangerous because they could be contaminated with the live, infec- tious agent. In fact, in a small number of instances, disease has actually been caused by vaccination. The human immune system responds to antigenic proteins on the surface of an infectious agent. By recombinant DNA techniques, these antigenic proteins can be produced, completely free of the infectious agent, and used in a vac- cine. The first successful recombinant DNA vaccine to be produced was for the hepatitis B virus. When Erna Nemdy began working with patients, she received the hepatitis B vaccine. The hepatitis B virus (HBV) infects the liver, causing severe damage. The virus contains a surface antigen (HBsAg) or coat protein for which the gene has been isolated. How- ever, because the protein is glycosylated, it could not be produced in E. The viral protein, separated from the small amount of contaminating yeast protein, is used as a vaccine for immunization against HBV infection.
