This invention discloses a parathyroid tissue transplantation device, belonging to the field of transplantation device technology, including a syringe, a cutting device, and a pusher. The cutting device has the same size as the inner wall of the syringe, and a through groove runs through the top surface of the cutting device. A material hopper is installed in the through groove, and the bottom surface of the material hopper is equipped with dense blades. A squeezing rod is placed in the material hopper, and a pusher plate is fixed at one end of the squeezing rod. The pusher plate has the same size as the inner wall of the material hopper. A drive component is installed inside the cutting device, which controls the rotation of the cutting blades. By setting up the syringe, cutting device, and pusher, the parathyroid tissue can be efficiently processed into a homogenate, realizing seamless linkage of tissue loading, cutting, and pushing. The entire process is completed in a closed structure, reducing tissue exposure, contamination, and residual loss. It realizes an integrated operation of immediate harvesting, processing, and transplantation during surgery, greatly improving the operation efficiency, standardization, and tissue survival rate of parathyroid tissue transplantation, and reducing the risk of postoperative hypoparathyroidism.

This document discloses compositions and methods involving glycosaminoglycan components. For example, administering a composition comprising a glycosaminoglycan component to an organ before, during, or after ex vivo organ perfusion can improve organ transplantation. These improvements include reduced MMP levels, reduced apoptosis markers, reduced endothelial cell activation, and increased organ function. Such methods and compositions can be used for organ and tissue transplantation, as well as for the storage or transport of acquired organs and tissues.

A tissue transplantation resin tip includes a needle tube for eyeball insertion. The needle tube includes a main body portion that extends linearly. A front end portion is bent with respect to the main body portion and extends linearly, with tissue discharging from the front end. The needle tube length is 25 mm to 50 mm, the front end portion cross sectional shape is oval with a major axis D1 of 0.8 mm to 1.5 mm and a minor axis D2 of 0.5 mm to 1.0 mm. The front end of the front end portion is a bevel surface that extends in a direction substantially perpendicular to the main body portion and has a bevel angle of 50° to 85°. The front end portion hardness is 0.15 N to 0.30 N or less and the center of the needle tube hardness is 0.80 N to 1.50 N.

The application discloses a preparation method of a composition for ovary transplantation and the composition. The composition comprises an antioxidant peptide and a colony stimulating factor. The antioxidant peptide in the composition of the application is attached to the colony stimulating factor, so that the antioxidant peptide can reach a ROS site, the antioxidant peptide can remove active oxygen generated by the ROS site and weaken the oxygen generation capacity of the ROS site, the antioxidant effect is improved, follicle loss is reduced, more follicles are protected, and finally the effect of frozen-thawed ovary tissue transplantation is improved.

Provided is a coating-fixing agent for transplanting a cell or a tissue onto the surface of an organ, intestinal membrane, peritoneal membrane, etc. Provided are: a formulation for coating and fixing a graft, the formulation comprising alginate; a formulation kit for coating and fixing a graft, comprising a formulation containing alginate and a divalent or higher valent metal salt in combination; and a method for transplanting a graft, comprising: transplanting the graft to a transplant site of a human or a non-human animal, and coating the graft with alginate.

The present disclosure relates to anti-CD40 antibodies, such as humanized anti-CD40 antibodies, that may be used in various therapeutic, prophylactic and diagnostic methods. The antibodies generally block the ability of CD40 to bind CD154 and do so without activating the cell expressing CD40 (e.g., a B cell). The present antibodies or fragments thereof may be used to reduce complications associated with organ or tissue transplantation.

To provide methods and compositions relating to isolated mitochondria.SOLUTION: Cells, tissues, or organs can be treated with isolated mitochondria, such as porcine mitochondria, to improve mitochondrial function in the cell, tissue, or organ. The improvements to mitochondrial function include increased oxygen consumption and increased ATP synthesis. Such methods and compositions are useful for cell therapy; organ and tissue transplantation; organ and tissue engineering; and cold storage or shipment of harvested organs, tissues, and cells.SELECTED DRAWING: Figure 1

Disclosed are devices and methods for delivering a sheet of tissue into the eye in such a way that damage to the tissue is minimized, damage to the eye during insertion and manipulation of the tissue is minimized, and the tissue is released and delivered in a precise and controlled fashion.

The invention relates to a pH sensor that can be embedded within a flap, allows wired or wireless operation, is biocompatible, does not require an additional power source thanks to its Schottky diode structure, and is capable of detecting the increase in tissue acidity caused by changes in blood flow and ischemia through ion exchange and closed-circuit currents. The pH sensor subject to the invention is suitable for use in the healthcare field, in areas dealing with tissue transplantation such as plastic surgery, hand surgery, and transplant surgery.

The present disclosure provides a mechanically-actuated tool for cutting a tissue graft having a hollow core and methods for use thereof. A portion of a biological structure, such as a nerve, is attached to the hollow core to form an implantable neural graft assembly. The tool has a cutter mechanism and a grasper mechanism. The grasper mechanism has one or more component(s) that open and close via an actuation mechanism, like a handle, and rotate via a controller component, like a rotatable wheel. The cutter mechanism may be a cutting tube component that harvests the tissue graft. The tool may also have an ejector mechanism to remove the tissue graft as part of the implantable neural graft assembly. Such devices and methods are particularly suitable for treating neuromas and other neural regeneration procedures.
