Inhalation of low levels of nitric oxide can rapidly and safely decrease pulmonary hypertension in mammals. A nitric oxide delivery system that converts nitrogen dioxide to nitric oxide employs a surface-active material, such as silica gel, coated with an aqueous solution of antioxidant, such as ascorbic acid.

In one embodiment, the present invention provides a biological sample capture device comprising a body including a chamber, the chamber being arranged to sealingly hold a biological sample, a first valve in communication with the chamber, wherein the first valve allows a biological sample to enter the chamber, a second valve in communication with the chamber, wherein the second valve is arranged to expel air from the chamber upon a biological sample entering the chamber via the first valve.

Some embodiments of an inhalation exposure system can deliver a gas, such as an aerosol, through a manifold to a set of exposure chambers in a controlled manner so as to achieve improved consistency for all of the test subjects.

Some embodiments of an inhalation exposure system can deliver a gas, such as an aerosol, to a set of exposure chambers in a controlled manner and can monitor one or more characteristics of the gas at a variety of aerosol delivery rates for output to a user interface. In some implementations, the improved user interface of the system may alert the user to a fitting range of aerosol delivery rates.

An equine respiratory prosthetic device comprising a nostril prosthesis, including a prosthesis body having a passageway therethrough and an adjacent protrusion for engagement with the nostril cavity and extending into the false nostril of an equine to secure the nostril prosthesis to the nostril.

A holding device for simultaneously holding several small animals includes at least three beds each for a small animal. Each bed is attached to a respective holder element. The holding device is geometrically constructed and mechanically configured where two of the holder elements can be moved together with their respective beds above a third holder element without changing the vertical orientation of the beds being attached to the two holder elements. This provides a compact holding device for a multitude of small animals facilitating flexible and easy access to each small animal when attached to the holder for generating a 3D image of all animals at the same time, e.g., in an MRI, PET, CT scanner or the like. The holding system is easy to use, in particular for rats or mice, and can easily be applied in a wide variety of locations through its small and compact construction.
