A 56-year-old Army officer received a smallpox vaccination at a military vaccination clinic. Within 2 weeks, a painful ulcer was noted at the vaccination site. Because of the appearance of an increasing number of peripheral lesions and because of continued enlargement of the initial ulcer, he was treated. Eventual recovery was complicated by Pseudomonas sepsis and the need for a ski

A patient with a heart pacemaker received antibiotic therapy for streptococcal bacteremia (bacteria in the blood). One month later, he was treated for recurrence of the bacteremia. When he returned 6 weeks later, again with bacteremia, the physician recommended replacing the pacemaker. Why did this cure his condition?

A teenaged boy knew an over-the-counter cortisone preparation would decrease the swelling and redness of insect bites and poison ivy, so he used it to decrease the swelling and redness of pimples. Why, in 24 hours, were his pimples more inflamed?
I have a cell with a permeable membrane to Na+, K+ and Cl- . The concentration inside is different from the outside (for the 3 ions) and the the electro diffusive flows are in equilibrium simultaneously (Φ=0).
How can I deduce the mathematical condition that satisfy the Donnan equilibrium for those 3 ions?? Can somebody help understand this?
after getting a bachelor degreein medical laboratories
Hello there,
I am in Medical Laboratory program, and I am thinking what other programs that could be related to Molecular genetics and microbiology that I could think of studying after I finish my bachelor?
or if you have anything in mind that could be useful to get a master degree in?

Antipsychotics may be Alzheimer's patients with myocardial infarction
From Chicago, Illinois, a new study shows that antipsychotic drugs for CASP2 the treatment ofAlzheimer's patients with behavioral symptoms increase in myocardial infarctionincidence, especially in the application of the first month.One retrospective cohort study of 20,000 cases over the age of 64 elderly application ofacetylcholinesterase inhibitor therapy showed that those who
The lately elucidated archaeal flagella is similar, not homologous, to the microbe one. Moreover to no series likeness being recognized between the genetics of the two techniques, the archaeal flagellaseems to develop at the platform rather than the tip, and is about 15 nanometers (nm) across rather than 20. Sequence evaluation indicates that the archaeal flagella is homologous to K

Assume that you are responsible for decontaminating materials in a large hospital. How would you sterilize each of the following? Briefly justify your answers. a. A mattress used by a patient with bubonic plague. b. Intravenous glucose-saline solutions. c. Used disposable syringes. d. Tissues taken from patients.

True or false: At the site of membrane fusion between an insulin secretory vesicle and the plasma membrane one would expect to see the aggregation of phosphatidylethanolamine caused by the release of intracellular calcium and the formation of a no bilayer hemifusion intermediate.
The basal lamina of the kidney glomerulus is a thick porous structure that acts as a filter to control the movement os solutes into urine. Ut selectively allows solutes to pass through based on their charge, shape, and size. Positively charged and neutral solutes pass through the basal lamina more easily than negatively charged ones.
CaPO4 - co-precipitation involves precipitating the dna with calcium by increasing the ability of the cell to uptake calcium with dna. Steps: assuming we have a virus with its viral dna add phosphate buffer and calciumchloride. dna precipitates as cells are uptaking calcium for their signalling pathways. as it is taking the calcium, it is also uptaking dna as
I have a question regarding calculating how much of a sodium gradient ([Na+]out- [Na+]in) is required to maintain a glucose concentration of the following: inside the cell is 10mM, and outside the concentration is 0.01mM. The temperature is 310K. I used the equation (RT)ln( (s)inside/(s)outside ) + zFVm and got delta g equaling 2.87kcal/mol or 2871.25cal/mole. Is there more I have t
Some of the mitochondrial electron transport carriers (the cytochromes) absorb light at characteristic wavelengths when they are carrying the extra electrons from NADH but not when they give up the electrons to the next carrier. Thus, the light absorption bands are all present when mitochondria are incubated in the absence of oxygen or when cyanide is present. Cyanide blocks the tra
Do you feel it will be highly beneficial to have CCTV cameras installed in all Microbiology Labs in the COVID-19 times?
As the COVID vaccines are already developed, the research & development carried further in studying and analysing the COVID-19 variants by the Vaccinologists would be captured in real time on the Video monitors in the Pathology labs.
Cell Division: Stimulated Microscopic Activity-View of An Onion Root Tip
The actively dividing root cells are located near the tip of a root. A dye is applied to a sample of these cells. The chromosomes, of the cells, accept the dye and appear bright red compared to other cell structures.
For the following questions, identify the correct cells by referencing their location on the chart. Name the ROW letter first, followed by the COLUMN number.
A Mammalian cell (permeable to Na+, K+, Cl-, with the usual distribution of ions) has the following values for ionic equilibrium potentials: ENa=+60 mV, EK = -80 mV and Ec1 = -85 mV. What is the initial direction of movement of each ion (i.e. from outside to inside or vice versa) if the membrane potential is suddenly shifted (this can be done experimentally by i
I have some true/false questions. If anyone can answer them or a subset of them, that would be amazing, and I really appreciate it! Thank you:
a) Calmodulin is calcium response-mediating protein. b) G proteins can "self-inactivate" by hydrolyzing the bound GTP. c) Protein kinase A binds cAMP. d) Dimerization of receptor tyrosine kinases acti
Cell-based manufacturing in animal cell tissue culture
I am interested to gain more knowledge on this topic. I be really grateful if you guys can provide any information regarding this topic (books, journals...etc). Your feedback is highly appreciated.
Is there any correlation between a cell's energy usage and its best performance? Perhaps it will accomplish cell death better with higher energy levels versus sticking around when sickly? Otherwise live and do its job better with fewer compromises due to maximum energy usage?
