CAM Therapies Compared to Traditional Allopathic Methods

Hello i am attaching article. This article attempts to understand the reasons some individuals turn to CAM therapies rather than traditional allopathic methods of healing. The authors specifically wish to create a profile of the most likely candidates to use CAM therapies. Findings indicate that a wide variety of factors and att

Acetylcholine Mother Bear Experience

Mark and Dave are hiking. The hikers surprise a mother bear and her two cubs on the trail. The mother bear makes it clear about being unhappy that she was surprised by the two hikers. Mark is taking a medication that specifically blocks muscarinic acetylcholine receptors and Dave is taking a medication that specifically blocks n

Adaptation and Altitude Sickness ("Chronic Mountain Sickness")

Individual who remain at high altitude for too long can develop chronic mountain sickness. It is characterized by the following clinical sequence: 1. an extremely high hematocrit, 2. an elevated pulmonary arterial pressure and 3. an enlarged right side of the heart. As it progresses, congestive heart failure and death ensues u

Action potential calculation with Nernst Equation

A population of typical neurons is maintained in culture in the lab. The media bathing the neurons has an extracellular concentration of Cl- of 110mmol/L. A particular neuron maintains an intracellular Cl- concentration of 4mmol/L. At what membrane potential could Cl- be closest to electrochemical equilibrium in that cell?

ANS Structure and Neural Pathways

The functions of this division of the nervous system are implied in its name! The ANS regulates the "automatic" functions of body...heartrate, respiration, digestion, just to name a few. Let's describe the structures of the ANS, along with their neural pathways! Then, let's discuss the negative feedback system needed for norm

Hormones and Sex Differentiation

The presence or absence of testosterone determines whether a mammal will differentiate as a male of female - estrogens have no effect. In birds, it is the opposite: the presence or absence of estrogen is critical. What problems would sex determination by estrogen create if that were the mechanism for mammals? Why do those proble

Physiological Effects of Various Hormones

1. After removing the painful kidney stone, which of the following might be part of a treatment plan and why? a. Low calcium diet b. Vitamin D c. Oral PTH therapy d. Surgery for removal of what part of the thyroid gland 2. For each of the following explain the physiological effects of excessive secretion of the following

Basic Functions of Kidneys' Filtration Role - An Analogy

Pretend you are cleaning your garage but the big door is stuck. You can only move things through the smaller "people" door. So the cars and riding lawn mower have to stay in the garage. This is analogous to the pores in the glomerulus. They are larger than ordinary capillary pores but still not large enough to let everything out

ovarian cancer

1) Describe ovarian cancer in biological terms and explain the impact at the level of cells and organ affected.

The Kidney and Alcohol

Please help with the following. Examine the body mechanics that occur when someone drinks alcohol: 1) How drinking alcohol affects the body's water volume. 2) How the kidney regulates blood volume. 3) How consumption of alcohol affects the kidney.

Analysis of Multiple State Obesity Charts

See the attached file(s). I am having trouble interpreting the 2 different tables that are attached (The tables are supposed to demonstrate how the BRFSS and CDC Wonder health databases can be used as a simple Decision Support System). Problem: 1. In a short paragraph, please summarize the tables to assist senior managem

hormonal feedback loops

1. Explain how hormonal feedback loops work. 2. What is a set-point? 3. What is leptin, and how does it affect appetite? 4. What role does the melanocortin 4 receptor, or MC4R, play in obesity? If someone asks you if obesity is genetic or behavioral, how would you respond? Do you think obesity is an epidemic? Why or

This solution details the types of infections that are common in three types of inherited immunodeficienies: complement C8 deficiency; X-linked agammaglobulinaemia (Bruton's disease); and selective IgA deficiency. It explains the underlying basis of why these patients are susceptible to these particular infections.

For each of the following conditions: 1) complement C8 deficiency: a defect that results in the functional absence of the eighth complement cascade. C8 is involved in the complement lytic pathway. 2) X- linked agammaglobulinaemia (Bruton's disease) :This affects an enzyme that is required for B cell development so pre B cell

Comparing Internal and External Antigen Presentation Pathways

Describe the similarities and differences between the processing of intracellular vs extracellular antigens. Provide a table detailing these similarities and differences. Compare and contrast the internal and external pathways of antigen processing and presentation to T cells. Make a table with 2 columns (one for each path

The Risk Factors for Mycotoxicosis in Food Producing Animals

Please address the following about Patulin: 1.) The effect of patulin on the appropriate food animal(s). 2.) The food safety/public health of each patulin. 3.) The risk factors for mycotoxicosis in food producing animals and how the appropriate animal exposure to mycotoxins can be prevented at the pre-harvest level. Not

Rapidly Dividing Tissue Types

Certain cells in the body stay in Gap 0 and rarely, if ever, divide. Name 2 cell types in the human body that do not divide. Other cell types in the body divide frequently (cycle fast). Name 1 tissue type in the body that divides often. Why does this tissue type need to divide frequently?

Diabetes Mellitus

What are the similarities and differences between starvation and diabetes mellitus?

Five questions addressing hormones and metabolism

Case Study 3: Gigantism is abnormally large growth during childhood caused by excess growth hormone secreted by the anterior pituitary gland. Robert Wadlow, born on February 22, 1918, weighed a normal eight pounds, six ounces. However, by the time Robert reached the age of six months old, he weighed 30 pounds (Hamilton, 1993). W
