Library Assignment

Part 1. Searching Techniques (20 pts)

The purpose of this exercise is to familiarize you with searching scientific literature to gain additional information about particular topics. Formerly, this work was done exclusively in a library utilizing multi-volume, bound resources such as The Science Citation Index, Biological Abstracts, etc. Thankfully, it is much more convenient to conduct these searches at a computer terminal using the internet.

Library Assignment

Part 1. Searching Techniques (20 pts)

The purpose of this exercise is to familiarize you with searching scientific literature to gain additional information about particular topics. Formerly, this work was done exclusively in a library utilizing multi-volume, bound resources such as The Science Citation Index, Biological Abstracts, etc. Thankfully, it is much more convenient to conduct these searches at a computer terminal using the internet. Your assignment is to identify three key words associated with a cell physiology topic of your interest (some examples are provided below), and use an internet library resource to locate ten journal articles that address this topic from the last 5 years. You must then construct a bibliography in which these ten literature references are listed in alphabetical order in a standard journal format. You may use any format of your choice, as long as it includes the title of the article. The chosen format must be a standard format found in the reference section of a journal article that is typically in use, and it must be consistent for each listing. One example of an acceptable format is:

Gardner, P.L., G.N.K. Mbuy, M.T. Knabb. (1994) Effects of the angiotensin II antagonist
losartan on herpes simplex virus-type 2 infection of cultured vero and cardiac neonatal
myocytes. Life Sci. 55(4): 283-289.

You must then choose one of these articles, download the abstract from the internet and print a hard copy. You may use any internet resource of your choice. PubMed is a particularly useful and convenient search engine. This tax-payer-funded resource is maintained by the National Library of Medicine, part of the National Institutes of Health. For simplicity, you may find the PubMed site address through a Google search using “PubMed” as the search topic. The West Chester University library also provides some excellent journal article search engines.

Discuss the concept that the nerve cell evolved from a cell that interacted with other cells using electrical synapse into the neuron that conveys specific unidirectional information that can be used to regulate other cells.

1] Describe the structure of a typical neuron. Include a BRIEF description of the function of the main structural components of the nerve cell.
A] Consider the mechanisms by which this cell has become responsive to the “stimulus” and how the neuron cause change in the next cell.
B] Given that one usually considers striated muscles as being organized in opposing pairs about the elements of the skeletal system (a bone is moved in one direction by one muscle and in the opposite by an opposing muscle), discuss the mechanisms that accomplish the integration of the functioning of the nerves responsible for the movement of a bone.
2] Explain how the three types of muscle cell evolved (specialized) from a stem cell type(myocyte) that interact with other cells(such as neurocytes, endothelial cells, myocytes, chondrocytes and osteocytes.) Include in this discussion concepts such as the structure of the three types of muscle cells. How does the structure of the cell relate to or account for
A] The type of synapse with the neuron or other cells?
B] The functional significance of unidirectional information in these three types of cell?
C] The particular role of that type of cell in homeostasis?

3] Discuss the concept that the nerve cell evolved from a cell that interacted with other cells using electrical synapse into the neuron that conveys specific unidirectional information that can be used to regulate other cells. Approach this discussion from the perspective of the processes that are responsible for the facilitating and inhibiting input that regulate the function of the cardiac pacemaker.
Include:
A) the mechanisms by which this regulation is transduced in the post synaptic membrane and how this affects the components of the movement of blood by the heart.
B) consider how the stimuli associated with homeostasis(pressure, pH, heart rate) are transduced into changes in the output of the heart to insure O2/CO2 homeostasis at the level of individual cells?

What would be the test results of his white blood cells, blood calcium levels, CT scan, and x-ray?

A 45-year-old grocery sales clerk has been suffering from bouts of severe pain in his left flank region. He blamed it on prolonged standing for 8 hours straight while working. He was taking over-the-counter pain medications for his pain. One day, he found fresh blood in his urine. He went to a doctor who performed urine tests, CT scans, and x-rays. He was diagnosed with urinary calculi.
Discuss possible factors that may have been responsible for the development of the stone and use this case to show how the patient’s diet and water intake can help analyze the composition of the calculi.

What would be the test results of his white blood cells, blood calcium levels, CT scan, and x-ray?

Suggest the best treatment for the patient and a plan to prevent recurrence post-treatment.
submit your responses to the above questions in a two- to three-page Word document.
