A blood sample from a patient is examined for the concentration of blood sugar and found to contain 135 ng/mL. A 5.00 mL portion of the blood sample was spiked with 1.75 μg of sugar. The measured response after the spike showed that the concentration of sugar is 385 ng/mL. Determine the percent recovery of this assay.

A 1.00 mL blank serum sample was spiked with 46.9×10−9 g of lisinopril, an angiotensin-converting enzyme inhibitor primarily used in the treatment of hypertension. The serum was prepared and analyzed using the normal laboratory method for the analysis of lisinopril that had previously been calibrated with aqueous lisinopril standards. The analysis of the spiked sample showed a measured lisinopril concentration of 45.8 μg/L. What is the percent recovery for lisinopril?

2. You are performing an assay to measure the TNF-a concentration in some patient serum sample. To perform the assay, you need a set of standards of known TNF-a concentration. How would you prepare TNF-a standards of 10, 50, 100, 250, 500 and 1,000 pg/ml from a 10 ng/ml TNF-a stock by serial dilution? [you need at least 200 ul of each for to perform the assay]

Exposure to arsenic in drinking water is associated with increased prevalence of diabetes. We previously reported an association of diabetes and urinary concentration of dimethylarsinite (DMAS"), a toxic product of arsenic methylation by arsenic (+ 3 oxidation state) methyltransferase (AS3MT). Here we examine associations between AS3MT polymorphism, arsenic metabolism and diabetes. Fasting blood glucose, oral glucose tolerance and self-reported diagnoses were used to identify diabetic individuals. Inorganic...

Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...
