In the normal lung, alveolar fluid clearance is tightly regulated, but in disease states, increased alveolar fluid can arise through alterations in Starling forces, including hydrostatic fluid forces (high-pressure edema), increased filtration coefficient, or reduced reflection coefficient, leading to epithelial permeability (lowpressure) edema. Regardless of the cause, alveolar edema elicits m...
the nasal cavity possesses many advantages as a site for drug delivery, such as, ease of administration, applicability for long term treatments and a large surface area for absorption. one important limiting factor for nasal drug delivery is the limited time available for absorption within the nasal cavity due to mucociliary clearance. several drug delivery systems including different kinds of ...
The visual cycle comprises a sequence of reactions that regenerate the visual pigment in photoreceptors during dark adaptation, starting with the reduction of all-trans retinal to all-trans retinol and its clearance from photoreceptors. We have followed the reduction of retinal and clearance of retinol within bleached outer segments of red rods isolated from salamander retina by measuring its i...
