The mechanism by which fluid retention by the kidneys and the stimulation of the heart by the sympathetic nervous systemcompensates for HF (heart failure). Introduction: HF is also referred as congestive heart failure. It is the condition in which the ability of the heart to function as a pump reduces by a great extent. Heart failure is generally caused due to decreased contractility. Conditions like myocardial infarction or myocardial ischemia and valvular heart diseases may cause decreased contractility of the heart. Myocardial infarction is a condition during which the blood supply to the heart is interrupted, which causes ischemia, or reduced oxygen supply, to that part of the heart. Heart failure results in a reduced stroke rate, as a result of which a reduced cardiac output (CO) is produced.

Svp je voulais demander l aide pour mon exercice

Imagine 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?

Respond 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.
