Urine and serum samples were transferred to the Chemical Core Analysis Facility of the Occupational and Environmental Health Sciences Institute (EOHSI), Rutgers University. ZEA and its metabolites were measured using an HPLC-MS-MS technique. 0.25 mL sodium acetate buffer (pH=4.65) and 10 μL of β-glucuronidase from Helix pomatia were added into 1mL of urine or serum sample. The enzymatic deconjugation was conducted in a water bath at 37 °C overnight. Then liquid-liquid extraction was performed on…

Procedure: To begin this experiment all of the equipment was collected. The materials used in this experiment were a small plastic weighing dish, oxalic acid, a 250 mL Erlenmeyer flask, distilled water, a buret, NaOH solution, a 150 mL beaker, funnel, and phenolphthalein indicator. Before the experiment began the buret was cleaned with distilled water, a buret brush, and dish soap. The buret was completely washed out in order to not cause any faults in the results of the experiment. Once the…

The health care specialist for the endocrine system is called a endocrinologist. The task which they are given is making sure that the body produces hormones the correct way. Thus making sure that the major organs and glands within the body get the proper medication need to flow freely and smoothly. Thus if glands are not performing properly they could cause risk or attracting cancer towards the body or cause organs to shut down. Overall the job and responsibilities of an endocrinologist are…

Medical Laboratory Technicians, I am thrilled to have a chance to advance my educational goals through this program. After I received my associate degree in medical laboratory technology and ASCP certification, I wanted to earn my bachelor degree in medical laboratory science while also gaining laboratory experience by working as a medical laboratory technician. Now I found my chance to do so. In the ever-changing healthcare industry and the advancement of technology in the clinical laboratory,…

Buret was rinsed with water and NaOH, and followed by filling with NaOH solution made in the first week of lab. An acid of unknown concentration was prepared by the instructor and given for analysis. 25.00 mL of the acid was transferred into an Erlenmeyer flask using a volumetric pipette and 2-3 drops of phenolphthalein were added. The resulting solution was titrated with NaOH to achieve the faint pink endpoint and [unknown] was calculated according to the volume of NaOH used. The purpose of…

While many trust Clemson's Deshaun Watson is the appropriate response, drafting the QB could really obliterate the New York Planes. A horrendous draft pick at number six would put Mike Maccagnan's employment at stake. Without question, he has an incredible arrangement to lose. As heads mentor Todd Bowles, who the Planes gave one more year to right the ship after one heartbreaking season. Bowles can't expect the Planes will be in an ideal situation drafting another newbie quarterback in a…

Title: Separations of a Mixture Notes: - H¬2O, Copper Sulfate, Starch - H2O (water)- liquid, solvent, boiling point: 100 C, freezing point: 0 C. - Copper Sulfate- solid, soluble, forms an aqueous solution, is a salt. - Starch- solid, macromolecule (long chain sugar), not very soluble in water at low temperatures. - When H2O, Copper Sulfate, and starch are mixed together, it forms a heterogeneous mixture. - Aqueous solution of copper sulfate with a suspension of starch. Research Question: What…

Preparing Dilutions of the Silver Nanoparticles 1. Gather all materials. 2. Put on a pair of disposable gloves. 3. Make a paper towel damp with some 70% isopropyl rubbing alcohol. Wipe down the work surface with the rubbing alcohol-dampened paper towel. 4. Using a permanent marker, label the five baby food jars #1 to #5. 5. Using the 25 milliliter (mL) graduated cylinder, measure and pour 22.5 mL of distilled water (from a new, unopened container) into each of jars #2, #3, #4, and #5. 6. Using…
