Secretase family of enzymes are central to the processing of amyloid precursor proteins (APP) associated with the development of Alzheimer's disease. They have garnered much attention over the years as a possible therapeutic target for the disease. Would targeting these enzymes for inhibition be an effective strategy for preventing the onset of Alzheimer's related amyloid plaque formation. If not, can you think of another approach that might be effective that doesn't necessarily involve targeting these enzymes?

Please explain the following:

Understand the family of TGF beta signaling molecules (ligands).

Understand that the TGF beta superfamily of growth factor ligands are synthesized and secreted in an Inactive form, and need to be activated extracellularly by proteolytic cleavage.

Understand the structure of the bioactive form of TGF beta.

Understand the family of TGF beta receptor structure and function

Using an online research tool such as the A-Z index on the CDC website, explain why Listeria monocytogenes is a major threat to pregnant women and their developing fetuses, who are ten times more likely to get sick than other demographic groups. (5 points)

In a comparative Anatomy lab, you found some bones and the jaws are toothed and that the anterior limbs are modified for flight. Determine whether this tetrapod is related phylogenetically to the subclass Archosauria of the Reptilia, to either the subclass Archaeornithes or the Neornithes of the Aves or to the subclass Eutheria of the Mammalia. Describe those aspects of the fossil which allows you to make your determination. IN OTHER WORDS, WHICH OF THE ABOVE ANIMALS POSSESS THE FEATURE, "jaws are toothed and that the anterior limbs are modified for flight." WHY?

Etanercept is a TNF-α antagonist composed of the dimeric fusion protein of extracellular ligand-binding portion of the soluble 75-kDa TNF-α receptor II and the fragment-crystallisable (Fc) portion of human immunoglobulin (IgG).” Based on this quote, what does etanercept compete with? Where does etanercept and its competitor bind?

Suppose that the researchers discovered that OFC and DLPFC patients have comparable P3 responses. First describe the pattern of results that Dynamic filtering theory would normally predict in this experiment, and then explain whether these hypothetical results would fit with that prediction.

Caleb Bakersfield, a 42-year-old real estate agent, had just returned from a vacation to Russia. His childhood had been rough because of an alcoholic and abusive father, and Caleb had started his own drug addiction in his early teens. By his early twenties, he was addicted to heroin, lived on the streets, and frequently used dirty needles. In his thirties, Caleb joined a program to beat his addiction and to turn his life around. The trip to Russia was to celebrate a decade of being clean.

Less than two months after his trip, Caleb started having respiratory complications, including a frequent cough and shortness of breath. He figured it was most likely a respiratory infection and made an appointment with his physician.

After listening to Caleb’s lungs, Dr. Bell determines that Caleb most likely has a lower respiratory infection and prescribes the antibiotic azithromycin. Dr. Bell reminds Caleb that it is important to complete his entire course of antibiotics, even if he feels better before he finishes all of the medicine. Dr. Bell also collects a sputum sample (mucus coughed up from the lower respiratory tract) and sends it to the laboratory for evaluation.
