MCB 234 Rasmussen College Vaccine Development for HIV and HCV Discussion
There are many opinions on the need and/or importance of vaccines in preventing the spread of disease. Our children are required to get vaccinations before entering school, and health care workers must have them when working in environments where they can encounter bloodborne pathogens.Human immunodeficiency virus ( HIV) and Hepatitis C ( HCV) are the two more prominent concerns for medical staff and for the worldwide community. Despite precautions, these diseases are both considered emerging infections. Neither of them have had vaccines developed that are effective at preventing the contraction of the disease.For your initial post, research the two diseases HIV and HCV. Based on your research, discuss whether you think that a vaccine will be developed for either of these diseases within the next ten years. Why or why not?

Cell Structure, Osmosis, and Diffusion
1. Answer the following questions:a. List four cell structures that are common to both plant and animal cells. (4 points)b. What structures are unique to plant cells? (2 points)c. What structures are unique to animal cells? (2 points)2. Below are five structures observed in cells. List the function of each structure. (5 points)a. Chloroplastsb. Golgi apparatusc. Ribosomesd. Central vacuolee. Rough endoplasmic reticulum3. William is observing a single-celled organism under a microscope and notices that it has a nucleus and iscovered in small, hair-like structures.a. Provide a probable name for this organism (1 point)b. Explain why William came to this conclusion. (2 points)4. Where in the cell are the chloroplasts located? (5 points)5. In the Spirogyra cells observed on the virtual microscope, about how many circular green chloroplasts wereseen in a single cell at 40X magnification? (2 points)6. What were the percent differences between the volumes of the potatoes in the osmosis experiment for eachsalt solution? (8 points)a. 0%b. 1.75%c. 3.5%d. 7%7. What extraneous variables might have affected how the results came out in the osmosis experiment? Describethree. (6 points)a.b.c.8. In osmosis, which direction does water move with respect to solute concentration? (2 points)9. Answer the following questions:a. Explain what would happen to a freshwater unicellular organism if it were suddenly released into asaltwater environment. Use the terms iissottoniicc, hyypottoniicc and hyypeerrttoniicc in the answer. (3 points)b. What would happen if a marine organism were placed in freshwater? (3 points)10. A student purchases and weighs 5 pounds of carrots from a local grocery store. She notices that the grocerystore constantly sprays its produce with distilled water. After returning home, she weighs the carrots again anddiscovers that they weigh only 4.2 lbs. They also no longer seem as crisp and taut. Provide a possibleexplanation for why the carrots weighed more at the store, based on the information learned in this lab. (5points)11. People always say that leeches can be removed from the body by pouring salt on them. Based on what thestudent learned about osmosis, provide an explanation that supports or refutes this information. (5 points)12. What is the surface-to-volume ratio and rate of diffusion for each potato cube from Procedure 3b? (6 points)a. Cube 1 surface-to-volume ratiob. Cube 1 rate of diffusionc. Cube 2 surface-to-volume ratiod. Cube 2 rate of diffusione. Cube 3 surface-to-volume ratiof. Cube 3 rate of diffusion13. Assume the potato cubes are cells. Which cube would be most efficient at moving materials into and out of thecube? Briefly explain the answer. (4 points)14. From what was observed in the potato procedure, how do the rate of diffusion and surface-to-volume ratio limitcell size? (5 points)15. One night, Hans decides to cook a hamburger and spaghetti with meatballs. To test ideas of surface-to-volumeratios, he makes a quarter pound hamburger and a quarter pound meatball and cooks them at the sametemperature. Which food item will cook the fastest and why? (5 points)16. While watching a special on animals, Brianna discovers that hares tend to lose heat through their ears. Based onthis and what is known about surface-to-volume ratios, propose an explanation as to why hares that live in hotclimates (such as the desert) have large, extended ears. (5 points)17. ((Applliiccaattiion)) How might the information gained from this lab pertaining to cell structures and diffusion beuseful to you in your everyday life or to a healthcare professional? (20 points)Key components of critical thinking and application include the following:1. Demonstrates application and comprehension of the scientific principles.2. Displays competence in applying scientific knowledge to your personal or professional life.3. Relevant content is supported by facts, data, and detailed examples.4.

Nightingale School of Nursing Massage Therapy Becker Muscular Dystrophy Case Study
There are nine types of muscular dystrophy, with each type involving an eventual loss of strength, increasing disability, and possible deformity. Pick one type and discuss it.There is no known cure for muscular dystrophy and the causes are complex and multifold. Stem Cell treatment, however, as a cutting edge treatment is showing some initial hope for success. Please research and discuss.Case Study ExampleLimb Girdle Muscular Dystrophy AGE:29 Gender: Male DIAGNOSIS: Limb Girdle Muscular Dystrophy (LGMD)Patient History: 6 Years ago, developed progressive weakness in his limb muscles. The Neurologist diagnosed LGMD.REASON FOR COMING FOR TREATMENT: The Patient had tried all available conventional treatments in the best of neurology hospitals in his country but with no improvement in his condition. The Patient was informed by the doctors that there is no treatment for this condition. He thought of trying new emerging treatments like stem cells, benefits of which he had heard about from other patients groups suffering from muscular dystrophies.TREATMENT: Mesenchymal Stem Cells Derived from Wharton’s Jelly of Human Umbilical cord. He Received 5 injections of stem cells, 3 Through Intravenous Route in a dose of 1 Million cells/kg body weight and 2 Injections of adequate cells through intrathecal route. BEFORE TREATMENT: There Was marked weakness in the muscles of all his limbs and in the power of shoulder, scapula and trunk muscles He Experienced difficulty in climbing stairs, walking and changing positions from sitting to standing position. He Fatigued easily and had diminished stamina for daily activities. Activities Such as combing hair, brushing teeth and eating with hands were difficult. However, He had no problem in writing.AFTER TREATMENT: The Following improvements were noticed after 3 Months of follow-up:There was improvement in the power of his shoulder muscles and now could raise his arms over the shoulder level.Due to this improvement, he could perform activities such as combing hair and brushing teeth with less effort.His confidence and stamina were elevated now.

NCSNSMT Teenage Development Discussion
Discussion Assignment:What is the endocrine disorder in this individual?Is the patient's delayed onset of puberty a primary or secondary disorder? Why?Why is HCG used in the treatment?Both FSH and HCG are needed in the treatment. Explain WhyCase StudyParents were concerned about their 16-year-old son for the following reasons: he had no deepening of his voice, scanty pubic and axillary hair growth, absence of beard and mustache growth, small penis, poor muscular development, and psychosocial immaturity.Laboratory evaluation indicated the following:Serum testosterone: 100ng/dLSperm count: 10 million/mL semenThe following tests were performed:Clomiphene (a nonsteroidal, weak estrogen agonist that stimulates the release of gonadotropins) 100 mg/day for seven days: 0% increase in LH (50% is normal)Gn-RH (100 µg I.V.): 0% increase in LH in twenty minutes (300% is normal)HCG (5000 I.U., I.V.): 50% increase in plasma testosterone one to three days after injectionThis person was subsequently treated with FSH at 25-75 U three times/week and HCG as described above. Sperm count and testosterone levels were both near normal after two months of treatment, and primary and secondary sex characteristics appeared.
