The invention provides novel methods for analyzing (e.g., imaging) drugs in mammalian tissues, and methods for identifying drug targets and analyzing drug-target interactions.

The present technology is directed to compounds, intermediates thereof, compositions thereof, medicaments thereof, and methods related to the imaging of mammalian tissue via 18F-labeled peptide ligands disclosed herein.

Described herein are systems, methods, and interconnecting porous hydrogel blocks for generating mammalian tissue. A block may comprise a three-dimensional continuous polymeric matrix with a network of microporous cavities, and may be configured to interconnect with at least one other block. A system may comprise a plurality of blocks configured to interconnect to form a scaffold configured to cultivate one or more cell types organized into stratified layers. A method may comprise acquiring a plurality of blocks, interconnecting the blocks to form a scaffold configured to cultivate one or more cell types organized into stratified layers, and seeding at least one block with at least one cell type adherent to the block. Embodiments may comprise perfusing at least one block with culture media and / or harvesting mammalian tissue generated.

Aspects and embodiments relate to a tissue mimicking material, a clinical phantom including a tissue mimicking material and a method of manufacture of a tissue mimicking material. According to one aspect there is provided: a tissue mimicking material comprising: an alginate matrix; and an ablation-sensitive agent distributed through the alginate matrix. Aspects and embodiments recognise that use of an alginate matrix as a base for a tissue mimicking material provides relatively low cost material having various physical properties and characteristics which can be tuned or refined to simulate the characteristics of a mammalian tissue which the alginate matrix is intended to mimic. In relation to use of an alginate material in the context of thermal and / or pulsed electric field ablation simulation, it has been recognised that an alginate material may be appropriately temperature stable and not degrade upon exposure to high, or low, ablation temperatures, or upon exposure to ablation levels of pulsed electric field. Distribution of an appropriately selected ablation-sensitive agent through the alginate material may allow a change caused by application of an ablation technique to the tissue mimicking material to be observed.

A method of sterilizing biological tissue such as soft mammalian tissue that can be used to make bioprosthetic devices is disclosed. The method comprises contacting biological tissue with a bioburden reduction mixture, contacting biological tissue with a tissue drying mixture, and thereafter sterilizing the dry tissue with supercritical carbon dioxide. Prior to sterilizing the biological tissue with supercritical carbon dioxide, the biological tissue is placed under vacuum and, in some embodiments, is treated with a vaporized microbicide. Bioprosthetic devices made using the methods disclosed herein include bioprosthetic heart valves, biological tissue derived vascular grafts or vessels, and surgical tissue patches.

Provided is use of a protein synthesis inhibitor in promoting regeneration and repair capacity of mammal tissues or complex structures or organs. The protein synthesis inhibitor is a small molecule compound, from any of cycloheximide or an Amaryllidaceae extract, capable of promoting regeneration of mammal tissues and organs.

Compositions and methods for providing the hybrid benefit of treating biofilms on the surface of mammalian tissue, especially biofilms that occur in association with chronic wounds and burns, and simultaneously providing an antiseptic cleansing and maintenance of the stratum corneum of the tissue and other tissue surfaces, and an opportunity for the tissue to improve by engaging its own natural barrier and immunological defense properties. The compositions and methods prevent the re-establishment of biofilms by facilitating the reduction or eradication of the pathogen producing the biofilm before the biofilm can be established.

A thermally representative phantom mammalian manikin assembly is provided. The assembly can include a cover portion representative of mammalian tissue partially enclosing a thermal cavity having a thermally representative material therein. The cover portion can have an opening with a cap extending across the opening and configured to further enclose the thermal cavity. The cap can have an aperture extending therethrough to receive a device extending through the aperture and into the thermally representative material within the thermal cavity. The device can be a thermocouple configured to measure a temperature of the thermally representative material. In assemblies representing mammalian limbs, the assembly can further include a second thermal cavity representing an additional portion of the limb, e.g., thermally representative upper and lower leg cavities.

Provided herein are compounds useful for inducing biostasis. Also provided are pharmaceutical compositions comprising the compounds, kits comprising the compounds, methods of inducing biostasis in subjects, biological samples and cells, and methods of preserving biological samples (e.g., mammalian tissue) by a compound or composition described herein.

The disclosure provides an antimicrobial composition comprising hypohalous acid and a salt of an organic acid, as well as methods of use for disinfecting mammalian tissue, including wounds and burns, and other uses.

Aspect and embodiments relate to a tissue mimicking material, a clinical phantom including a tissue mimicking material and a method of manufacture of a tissue mimicking material. One aspect provides a tissue mimicking material comprising: an elastomeric solid foam. The foam comprises gas pockets dispersed in an elastomeric material matrix and a liquid lubricant arranged within the gas pockets of the elastomeric solid foam. Aspects and embodiments recognise that a self lubricating tissue mimicking material provides a mechanism to emulate particular in vivo mammalian tissues. The modified foam material in accordance with aspects has various physical properties and characteristics which can be tuned or refined to simulate the characteristics of a mammalian tissue which the foam is intended to mimic.

Optical, geometric, and / or physiological characteristics of a mammal and / or a pregnant mammal's abdomen may be used to determine a personalized calibration formula for the respective mammal or pregnant mammal's abdomen. This personalized calibration formula may be used to analyze or evaluate light transmission data corresponding to an optical signal that is detected by a photodetector and converted into the light transmission data to determine an oximetry value for the mammal, pregnant mammal, and / or fetus. The optical signal may be a composite of light that was incident on the mammal or pregnant mammal's abdomen her fetus. On some occasions, an image of the mammal's tissue and / or the pregnant mammal's abdomen may be received and used to generate a tissue model of the respective mammal's tissue or maternal abdomen. The tissue model may be used to generate, or adjust, the personalized calibration formula.
