Abstract: A nasal irrigation system for rinsing nasal and sinus passages or cavities includes a solution preparation unit and a dispensing container. The solution preparation unit includes a first water reservoir, a filter that is in fluid communication with an outlet of the first water reservoir and filters water passing therethrough, a second water reservoir that is in fluid communication with the filter, and a heating element that brings filtered water in the second water reservoir to a boil to clean the filtered water, and a filler port. The dispensing container receives a nasal rinse solution from the solution preparation unit, via the filler port, and administers the nasal rinse solution to a user via a direct nostril interface. The solution preparation unit can also include a cooling element, additive reservoirs for materials to calibrate salinity or to provide a pH buffer, and a control circuit to control operation thereof.

Abstract: A thermally sensitive device having a thermochromic indicating member is described. The device is prepared from a thermally conductive material and has at one end an indicating member that is formed from a thermochromic material.

Abstract: A method for improving cellular gallium uptake (particularly of tumor cells) by exposing cells to a nifedipine photodegradation product, or an analog thereof. In particular embodiments, the gallium uptake enhancer is selected from the group of A-B and formula (I), wherein A is a pyridine and B is a nitrosophenyl, and n=1-10. In yet other embodiments, the uptake enhancer is formula (II), wherein R1-9 are independently selected from the group consisting of H, halogen, haloalkyl, NO2, NO, SO2, a C1-6 alkyl, a COOR10 wherein R10 is H or C1-6 alkyl, and an —OR11 wherein R11 is H or C1-6 alkyl; wherein at least one of R5 and R7 is NO. The uptake enhancers are particularly useful in imaging tumors, using such techniques as gallium scanning, in which the dose of the gallium isotope can be decreased or its imaging efficiency improved.
