Introduction:
Human blood group classification is based on two agglutinogens, A and B. Apart from these two agglutinogens, there is another type of agglutinogen, called agglutinogen D, that is found in human body. Agglutinogen D is responsible for Rh (Rhesus) blood classification. The person who carries agglutinogen D belongs to Rh+ (Rhesus positive) group and who lacks this agglutinogen belongs to Rh− (Rhesus negative) group.
Hemolysis means rupture of the red blood cells (RBCs). When an Rh− individual receives blood from an Rh+ person, the immune cells of Rh− person attack the agglutinogen D of Rh+ blood as an antigen. This causes rupture of the RBCs. Hemolysis does not occur in first-time blood transfusion as the body needs time to create antibodies against the Rh antigen. After the formation of antibodies, Rh− blood always reacts with Rh+ blood when both these blood types come in contact.

Drug X was developed to reduce blurred vision in healthy patients, but the effectiveness had not been tested on those suffering from multiple sclerosis. A study was conducted to determine if Drug X is effective at reducing blurry vision in multiple sclerosis patients. To be considered effective, a drug must reduce blurred vision by more than 30% in patients. Researchers predicted that a 20 mg dose of the drug would be effective for treating blurred vision in multiple sclerosis patients by reducing blurred vision by more than 30%. Drug X was administered to groups of multiple sclerosis patients at three doses (10 mg/day, 20 mg/day, 30 mg/day) for three weeks. A fourth group of patients was given a placebo containing no drug X for the same length of time. Vision clarity was measured for each patient before and after the three-week period using a standard vision test. The results were analyzed and graphed (See Figure…arrow_forward
- Svp je voulais demander l aide pour mon exercicearrow_forwardImagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?arrow_forwardRespond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.arrow_forward
