Her doctors determined her breast cancer wasaggressive, which meant that she needed to undergo chemotherapy. Her doctors recommended a combination of docetaxel (Taxotere®), carboplatin, and trastuzumab (Herceptin®). The following is her blog entry after her second chemo treatment: As far as chemo symptoms go, the biggest has been fatigue. I was just tired, grumpy, and not my usual, peppy self most of the week. Other very minor things—tiny bit of stomach upset at the beginning of the week, but just enough to make me not feel like eating a big steak, not enough to keep me from eating soup or sandwiches. My scalp felt a little irritated—for the girls out there, itwas the feeling of having my hair in a tight ponytail all day and then letting it down, and the follicles just feel prickly—this is normal for several daysbefore the hair falls out. Also, I have a weird dry mouth feeling, so some things taste a little different. But seriously, these are really minor…

- Explain why use of a 5 alpha reductase inhibitor is a treatment for benign prostate hyperplasia93. In an experiment to determine the effect of the route of administration of glucose on insulin secretion, a healthy 25-year-old man is given oral glucose and an equivalent dose of intravenous glucose on different days. Serum studies show that the insulin concentrations are greater after oral glucose than after intravenous glucose. In comparison with intravenous glucose, oral glucose augments insulin secretion by which of the following actions? A) Decreases secretion of glucagon B) Decreases secretion of somatostatin C) Increases secretion of acetylcholine D) Increases secretion of epinephrine E) Increases secretion of gastrointestinal hormones6. Increasing the aldosterone secretion during prolonged muscle activity in hot weather allows you to compensate for the sodium loss in sweat and remove the accumulated excess of potassium. Explain these biological effects of the hormone during exercise.

Explain these biological effects of the hormone during exercise. For answer: suruction starting with nonmonė c) explain the role of the hormone in the regulation of gene transcription and translation; d) describe the role of proteins that have their synthesis regulated by aldosterone.2. Researchers have discovered significant changes in the gene of some protein, which is a substrate for the insulin receptor. What impact on the insulin signal transduction would such changes have? For the answer: a) draw the scheme of insulin signal transduction in the target cell; b) name proteins and enzymes, activated by insulin in the target cells; c) explain the functions of these enzymes.GIVE GRAPHICAL MODEL BASED ON GIVEN INFORMATION: There are three elements in this specific model: Alpha Secretase: This node represents the variable or concept of Alpha Secretase, a proteolytic enzyme that cleaves Beta-Amyloid molecules. Beta-Amyloid Formation: This node represents the variable or concept of Beta-Amyloid Formation, which describes the process of the formation and accumulation of Beta-Amyloid protein in the brain. It is regarded as toxic and contributes to the onset of Alzheimer's disease. Calcium signaling: This node represents the variable or concept of Calcium Signaling, which refers to the cellular process involving the regulation and influx of calcium ions. Alzheimer's disease is known to influence calcium signaling pathways. The directed edges in the graph indicate the causal relationships between the variables. The situation: There is a directed edge between Alpha Secretase and Beta-Amyloid Formation, indicating that Alpha Secretase has a direct…
