What is the processing leaf litter (steps) in first-order streams?

Kainic acid was one of the first compounds used to model TLE in rodents. What is(are) its molecular target(s) and how would this compound lead to seizures?

Antibody titer is a measure of activity, not actual concentration. Explain why titer is a measure of activity, not a concentration. Please use the following example: You have anti-sheep red blood cells from two different companies, both with the same concentration, but one has a high titer and one with a low titer.

Is the cytosol and intermembrane space of the nuclear envelope topologically equivalent?

Explain the difference between nonspecific binding and specific binding using an indirect ELISA as an example. For this assay, assume that you are determining the titer of antibody against BSA.

You bind BSA to wells of a microtiter plate, add a dilution series of the antibody in question across the wells of the plate, then detect that antibody with an enzyme-conjugated antibody/chromogenic substrate pair.

Disruption or elimination of normal microbiota may lead to disease. Explain with examples.

Thank you for your help!

Oxidative phosphorylation is dependent on all of the following EXCEPT:

a. an intact mitochondrial membrane

b. the activity of ATP-ADP translocase

c. the reduction-oxidation state of iron

d. the reduction of oxygen

e. there are no exceptions. It is dependent on all A-D.

How might the information gained from this lab pertaining to mitosis and meiosis be useful to you as a healthcare professional? (20 points)

In Community X (population 20,000), an epidemiologist conducted a prevalence survey in January of 2012 and reported an HIV prevalence of 2.2%. Over the next 12 months, the department of health reported an additional 50 new HIV cases between February 2012 and January 2013. The total population stayed constant at 20,000. Part 1 How many people had HIV in January 2012? Present or describe the formula you used to arrive at your answer. Calculate the incidence rate assuming no HIV-related deaths over the 12-month period. Present or describe the formula you used to arrive at your answer. Be sure to clearly indicate the numerator and denominator used in your calculation and include an appropriate label for the rate. In a summary of 200-250 words, interpret the results and discuss the relationship between incidence and prevalence. Discuss whether or not the epidemiologist should be concerned about these new HIV infections, assuming a previous incidence rate of 0.5 per 1,000 person-years prior to this updated risk assessment. Part 2 A rapid test used for diagnosing HIV has a sensitivity of 99.1% and a specificity of 90%. Based on the population prevalence of 2.2% in 2012, create a 2x2 table showing the number of true positives, false positives, false negatives, and true negatives. Calculate the positive predicative value and negative predictive value for this test
