This the continuity of the paper I attache the first part then you will see the second part instruction either. don’t give me .com in on it please. the one you see with the title” Deadly Broom” is a model of how you have to do the second part. This is the continuity of the same topic but you have to call this part “Methods and Materials” But the big title is “Why People Die from Prescription Drugs”. I attache the one that have the title of “Why People Die from Prescription Drugs” you will continued wit it with the instructions I attached please follow the instruction for me please. I just need 5 references.

Methods and Materials

BMAA is a neurotoxin that has been linked to Alzheimer’s and other neurological diseases. To investigate the presence of BMAA and its correlation to Alzheimer’s diagnosis a research study was conducted. With the permission of family members doctors at the National Institute of Neurological Disorders and Stroke gathered forty brain tissue samples to complete their experiment. Twenty of the samples came from people that had been diagnosed with Alzheimer’s, were deceased and were named the experimental group the other twenty who died of other causes, were named the control group. To find out if BMAA is an underlying cause of Alzheimer’s autopsy was performed to the forty patients who were diagnosed with Alzheimer’s as well as the controls.

Standard procedures were used to remove the brains, which include “cutting the nerves to the blood vessels to the brain, the fibrous attachment to the skull and the nerves to the eyes,” (Encyclopedia, n.d). Twenty of the deceased had diagnoses of Alzheimer’s while living and the remaining twenty had not victims of Alzheimer’s disease. After obtaining the brains, pilling the lining of the surface of the brain from both the experimental and control group, data collection for both was obtained.

To confirm a correlation between the presence of BMAA and Alzheimer diagnoses medical examiners performed an autopsy and removed the entire brain from forty deceased bodies. Examining the external features of the brain to identify atrophy. The brains were then placed in a cylinder filled with fluid to distinguish the average volume between the control and experimental group. Using a knife, the examiner cut each brain in half to evaluate the difference between a healthy brain and an Alzheimer brain. Each brain was cut into smaller pieces to identify any similarities and differences (Gentleman, 2012).

The medical examiners used enzyme-linked immunosorbent assay (ELISA), which are used to detect the presence of antigen antibody in a sample (ELISA-antibody, n.d). The first step the examiners took in determining the presence of BMAA in the brain tissue was the use of standard solution. The medical providers added fifty microliters of solutions to the control and experimental group’s wells of the test strips. Secondly, the medical attendant added fifty microliters of enzyme conjugate to each wells using a pipette. Following, the addition of the enzyme conjugate, addition of fifty microliters of antibody solution was added to the individual wells. After the solution was added, tape was used to cover the wells then mixture of the contents was done, along with incubation for sixty minutes. The fourth step in determining the presence of BMAA was removing the tape and disposing the contents into a sink. 250 microliters of washing buffer was used to clean the wells. Next, 100 microliters of substrate color solution was added to each wells. During this step, the examiners covered the wells with tape and mixed the contents together, then incubated for thirty minutes. The sixth step for the examiners was adding 100 microliters of stop solutions using a multi-channel pipette. The final step in determining the presence was to calculate the results” (Abraxis, n.d).

Health examiners were able to determine if BMAA was truly present in the brain of the experimental group. Also if its present in the brains of some of the control group.
