An improved biopsy tray includes a container having bottom surface and continuous perimeter wall extending upward therefrom to form a cleaning zone which is sufficient to hold an adequate amount of fluid for cleaning a biopsy forceps, and at least one specimen bottle receiving receptacle adjacent the perimeter wall to receive and retain a specimen bottle. A method of obtaining a biopsy specimen includes employing the tray of the invention.

A hybrid germicidal irradiation apparatus, method, and system for multi-band germicidal irradiation. A first emitter, a second emitter and a third emitter may be coupled to a housing configured to be coupled to a ceiling of an interior room. The first emitter, the second emitter and the third emitter may respectively be operable to emit UV-C radiation at a wavelength of about 265 nanometers, near-UV radiation at a wavelength of about 405 nanometers and visible light at a wavelength greater than 405 nanometers. One or more radiation sensors may be configured to measure the amount of UV-C light, near UV-C light and/or visible light reflected from a target surface. A controller may be communicably engaged with the radiation sensors to calculate an amount of UV-C radiation, near-UV radiation and/or visible light delivered to a target surface or interior space.

A non-destructive and reversible process to deodorize Nannochloropsis algae is provided.

There is disclosed a method of engineering bacteriophages comprising: identifying a bacteriophage with only one attachment gene; isolating said bacteriophage; removing said attachment gene from the genome of said bacteriophage; and inserting a non-natural attachment gene into the genome of said bacteriophage wherein said non-natural attachment gene is specific for attaching to a selected bacteria. There is also disclosed a mutant bacteriophage comprising a heterologous nucleic acid sequence encoding a first specific attachment gene, the first specific attachment gene being different than an inactivated attachment gene and being specific for a selected bacteria. In another embodiment, there is disclosed a method of eliminating a microbial contaminant, the method comprising: obtaining one or more lytic enzymes produced by a mutant bacteriophage; applying the one or more lytic enzymes to a bacterial contaminant, without prior infection of the bacterial contaminant with a bacteriophage, to eliminate the bacterial contaminant.

A personnel tracking and disinfecting system is applied to a place and includes recognition devices, at least one disinfecting device, storage and central controller. The central controller is configured to: control the recognition devices to recognize the person in the place; determine the position of the person in the place by cooperating with the recognition devices; activate the disinfecting device in the main area to disinfect the person in the main area, generate a disinfecting record based on recognition result generated by the recognition device in the main area, and store the disinfecting record in the storage; and determine whether the person in the extended area has the disinfecting record based on recognition result generated by the recognition device in the extended area.

The present disclosure provides apparatuses and systems for delivering a measureable absorbed-dose of a gaseous activating agent to a fluid including a biological liquid and/or cells. The apparatuses or systems include a gas-fluid contact device configured to controllably rotate or oscillate a control member having an interior surface in contact with the fluid and a control system configured to control rotation or oscillation of the contact member by the gas-fluid contact device. In some embodiments, the control system is further configured to control absorption of the gaseous activating agent by the fluid. The present disclosure also provides methods of treating a fluid including a biological liquid or cells with a gaseous activating agent to controllably activate the fluid.

A method for detaching, removing or otherwise disrupting bacteria or biofilm by applying with pressure an antimicrobial wash. The antimicrobial wash contains a biguanide compound or mixtures thereof.

The invention relates to a viral inactivated biological liquid or dry mixture and to its preparation. Principally, the invention relates, but is not limited, to a mixture derived from a platelet source.

A vessel harvesting apparatus for removing a blood vessel from a patient includes collection and conditioning (i.e., treatment) of expelled insufflation gas prior to releasing the gas into the air of the operating room. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. An insufflation channel is configured to convey an insufflation gas subcutaneously into a dissected space within the patient. A removal channel is configured to evacuate fluidic contents from the dissected space, wherein the fluidic contents include insufflation gas and biological impurities. A processor/separator is coupled to the removal channel to process the fluidic contents to retain at least some of the biological impurities and to exhaust the insufflation gas.
