The steroid nandrolone, which is found naturally in horses, is administered to racing horses to aid in recovery. Because it is ananabolic steroid, nandrolone levels in excess of normal background levels disqualify a horse from racing. For example, to race inthe Kentucky Derby, a gelding (a castrated male horse) may have no more than 1 ng/mL in the urine, whereas an unaltered malehorse may have no more than 45 ng/mL of the metabolite estrane-3,17-diol in the urine.Knowing that nandrolone is an anabolic steroid, whichhormone would you expect it to closely resemble?(testosteronecortisolO progesteroneO epinephrineantidiuretic hormoneDuring metabolism, carbon 3 and carbon 4 of nandrolone are reduced, forming the metabolite estrane-3,17-diol.

Type I diabetes is caused by destruction of the beta cells of the pancreas, the cells that produce insulin. In most cases, the beta cells are destroyed by an immune response. Both genetic and environmental factors are involved in triggering the immune response. NOD mice develop a disease very much like Type I diabetes. (NOD mouse = non-obese, diabetic, mouse). If you transfer plasma from a NOD mouse to a normal mouse, the normal is not affected. If you transfer lymphocytes (WBCs white blood cells) from a NOD mouse, the normal mouse develops diabetes. The first people to figure this out found they had to transfer two types of WBC to transfer diabetes. After some experiments, they found that under the right conditions, they only had to transfer one type of cell to cause diabetes in the recipient. B-1. Consider the one type of WBC that can cause diabetes by itself. Which type is it likely to be? (B cells) (helper T cells) (cytotoxic T cells) (either type of T cell) (any of these)…
Endurance athletes sometimes try an illegal method of blood doping called autologous transfusion. Some blood from the athlete is removed well before competition, and then transfused back into the athlete just before competition. (a) Why might blood transfusion benefit the athlete? (b) With time, stored red blood cells become depleted in 2,3-BPG. What might be the consequences of using such blood for a blood transfusion?

JH, a 53 year-old female, had not been feeling well lately and suddenly started to feel acutely worse. She started to have shortness of breath, and was experiencing an irregular heartbeat, chest pain, muscle weakness, and feelings of severe nausea. She called 911 and was taken to the hospital where blood samples were drawn. The following table summarizes the results of her bloodwork (Table 1) Table 1: JH ion concentrations at intake (blood). lon Plasma concentration - measured (mM) Plasma concentration - normal (mM) K+ 8 5 Na+ 142 142 Cl- 105 105 Ca2+ 2.5 2.5 JH was diagnosed with hyperkalemia and ordered IV fluids.

We graphed the standard curve using the bovine serum protein solution. We then extracted albumin and globulin from egg whites. After getting the absorbance values for our samples, we used the standard curve from the bovine protein data to calculate the unknows of our albumin and globulin concentrations. Was it appropriate to use bovine serum protein as the standard when you were analyzing egg proteins in your unknown? Explain.

You are working in the hospital today and you have to give ECG stress tests to two different patients. One patient is a renowned professional athlete (such as a football or basketball player) who has a physical workout 6 days a week. Another patient is obese and elderly with Type II diabetes mellitus not under control. This patient also has a sedentary lifestyle. What would you expect to see in each of their electrocardiograms before and after each stress test? Would there possibly be any differences in the results of their electrocardiogram?
