Disclosed are instruments and methods for acquiring co-registered orthogonal fluorescence and photoacoustic volumetric projections of an interrogated object. In an embodiment, an instrument includes a rotary mechanism configured to rotate an interrogated object relative to an array of photoacoustic transducers and an optical detector. An optical excitation unit is configured to irradiate the interrogated object with pulses of light, inducing both fluorescence and photoacoustic responses inside the interrogated object at each of a plurality of rotational positions. The array of photoacoustic transducers includes unfocused elements arranged in a pattern along an axis of rotation, the elements configured to detect photoacoustic signals generated inside the volume of the interrogated object. The optical detector is arranged opposite to the array of photoacoustic transducers with respect to the axis of rotation and is configured to register sources of fluorescence excited inside the interrogated object. Each of the optical excitation axes form with each of the optical detection axes, and with each of the photoacoustic detection axes, angles that are between 60 and 90 so as to enable acquisition of co-registered orthogonal fluorescence and photoacoustic volumetric projections of the interrogated object.

A sprayable cooling composition comprising at least one refrigerant (DME) as well as at least one non-volatile antiseptic agent (cetrimide), wherein the cooling composition is capable of eliciting both a local refrigerant effect to a body surface area to which it is applied and providing antisepsis due to the non-volatile antiseptic agent remaining on the body surface area. The composition is useful for surgical and animal husbandry procedures, such as piglet castration.

A method and apparatus for anesthetizing animals is provided. The system is particularly suited for anesthetizing small laboratory animals such as mice, rats and similar mammals. The system may include a plurality of discharge elements such as breathers and/or chambers that are configured to direct the flow of anesthetizing fluid to the animals. Additionally, the system is designed to provide a flow of anesthetizing fluid at a constant flow rate to a plurality of discharge elements. The system includes a fluid controller that controls the flow of anesthetizing gas to provide a constant mass flow rate of anesthetizing gas during a procedure as the number of discharge elements that receive anesthetizing gas varies over time.
