Case study:  Moira Moira is a 54-year-old female with a two-day history of a pulsating/throbbing headache which is worse with movement and physical activity.  She describes photophobia and phonophobia.  She is nauseated but has not vomited.  Moira describes the pain as 6-7/10, with 10 being the worst pain imaginable.  The pain began while at work 2 days ago.  It started with her seeing what she describes as halos around lights.  Moira has a history of migraine headaches.  She has been given naproxen sodium 500 mg. tablet, to take at onset of headache and then every 12 hours as needed for pain.  She has taken it as prescribed, but the headache has not resolved.  Moira is very frustrated.  She has these types of headaches approximately 5 days out of the month and often misses 1-2 days of work each month due to these migraines.  Moira reports no change in the frequency or intensity of these headaches, but no longer feels the current treatment plan is effective.  She has not been to work since this headache began 2 days ago.  Based on what you know, what is your diagnosis? Are there any diagnostic tests you would order? What is your treatment plan for Moira going forward?  Include any changes you would make to the current treatment plan. Please include patient teaching

Coherent light with wavelength 450 nm is incident upon a pair of slits. The interference pattern produced on a screen 2.0 m from the slits is measured to have a separation between two adjacent bright fringes of 1.8 mm. Next, a laser with an unknown wavelength shines upon these same pair of slits and screen. The interference pattern shows the distance between adjacent bright fringes is 0.5mm. What is the wavelength of this mystery laser, in nm?

Use the following description to answer the question(s) below.In the ocean, on either side of the Isthmus of Panama, are thirty species of snapping shrimp; some are shallow-water species, others are adapted to deep water. There are fifteen species on the Pacific side and fifteen different species on the Atlantic side. The Isthmus of Panama started rising about ten million years ago. The oceans were completely separated by the isthmus about three million years ago.In the following figure, the isthmus separates the Pacific Ocean on the left (side A) from the Atlantic Ocean on the right (side B). The seawater on either side of the isthmus is separated into five depth habitats (1-5), with 1 being the shallowest.Which factor is most important for explaining why there are equal numbers of snapping shrimp species on either side of the isthmus?

Which of the following information or processes does gene therapy require?
