Concept explainers
To discuss:
The important features of the other lower respiratory tract diseases, community-acquired and healthcare-associated pneumonia.
Introduction:
“Streptococcus pneumonia” is a gram-positive bacterium, which found in pairs of cocci and is non-motile. Its virulence is determined by the chemical composition of its capsule. According to polysaccharide capsule composition Streptococcus pneumonia is found in ninety serotypes.
Pneumonia defined is an inflammatory condition of the lung in which fluid fills the alveoli. Community-acquired pneumonia generally occurred in a population. Healthcare-associated pneumonia develops in individuals receiving treatment at health care facilities and hospitals.

- You intend to insert patched dominant negative DNA into the left half of the neural tube of a chick. 1) Which side of the neural tube would you put the positive electrode to ensure that the DNA ends up on the left side? 2) What would be the internal (within the embryo) control for this experiment? 3) How can you be sure that the electroporation method itself is not impacting the embryo? 4) What would you do to ensure that the electroporation is working? How can you tell?arrow_forwardDescribe a method to document the diffusion path and gradient of Sonic Hedgehog through the chicken embryo. If modifying the protein, what is one thing you have to consider in regards to maintaining the protein’s function?arrow_forwardThe following table is from Kumar et. al.

- The following figure is from Caterina et al. The capsaicin receptor: a heat activated ion channel in the pain pathway. Nature, 1997. Black boxes indicate capsaicin, white circles indicate resinferatoxin. You are a chef in a fancy new science-themed restaurant. You have a recipe that calls for 1 teaspoon of resinferatoxin, but you feel uncomfortable serving foods with "toxins" in them. How much capsaicin could you substitute instead?arrow_forwardWhat protein is necessary for packaging acetylcholine into synaptic vesicles?arrow_forward1.
