The present invention refers to field of assisted reproductive technologies, in particular to a sperm storage media, and describes mTOR enhancers, preferably the mTOR activator MHY 1485, as supplement for storage media, said supplemented media increasing sperm motility and viability during short-term room temperature storage, while sustaining the metabolic rates, without changing its fertilization potential (capacitation) and DNA integrity.

Provided are a cryopreservation liquid for bovine reproductive cells such as bovine sperms and a cryopreservation method thereof. Adopted is a cryopreservation liquid comprising: 0.3 to 0.9 w/w % of an amphoteric polyelectrolyte (an antifreeze polyamino acid), which is ε-poly-L-lysine having a number average molecular weight of 1,000 to 20,000 wherein 50 to 99 mol % of amino groups of the ε-poly-L-lysine are blocked as carboxylated by having been reacted with the succinic anhydride; and 2 to 4 w/w % of glycerol, as dissolved in a physiological solution. A preferred embodiment of the cryopreservation method comprises steps of: primary diluting, in which bovine semen is diluted to 2.5 to 10 times with a physiological solution and kept at 2 to 8° C.; and secondary diluting, in which the bovine semen is diluted to 5 to 20 times while being kept at 2 to 8° C., by adding dropwise a physiological solution containing the amphoteric polyelectrolyte (antifreeze polyamino acid) and glycerol to a suspension obtained in the primary diluting.

The present invention provides improved and/or shortened methods for expanding TILs and producing therapeutic populations of TILs, including novel methods for expanding TIL populations in a closed system that lead to improved efficacy, improved phenotype, and increased metabolic health of the TILs in a shorter time period, while allowing for reduced microbial contamination as well as decreased costs. The methods may comprise gene-editing at least a portion of the TILs to enhance their therapeutic efficacy. Such TILs find use in therapeutic treatment regimens.

A specimen holder includes a stick and an RFID tag. The stick is elongate along a longitudinal direction, and has a distal end and a proximal end opposite the distal end with respect to the longitudinal direction. The stick includes an outer surface and a distal portion of the outer surface that is closer to the distal end than the proximal end. The stick further includes an internal cavity that extends from a first terminal end to a second terminal end. The stick includes a midplane that is normal to the longitudinal direction, and the midplane is located equidistant between the distal end and the proximal end. The first terminal end, the second terminal end and an entirety of the internal cavity are all located between the midplane and the proximal end. The RFID tag is positioned within the internal cavity.

Provided herein are compositions comprising ergothioneine (e.g., a natural form of purified L-ergothioneine) and methods of using such compositions, e.g., for improving cell viability, maintaining telomere length, or treating telomere-related disorders. In some embodiments, the ergothioneine has a purity of at least or about 98%.

A cryopreservation process includes combining a cryopreservation composition with a biological sample. The cryopreservation composition includes at least one glycerol ester component. The cryopreservation process also includes then cooling the cryopreservation composition with the biological sample to a cryopreservation temperature. The cryopreservation composition aids in cryopreserving the biological sample at the cryopreservation temperature. A cryopreservation composition includes at least one glycerol ester component. A cryopreserved system includes a biological sample in a cryopreservation composition at a cryopreservation temperature. The cryopreservation composition includes at least one glycerol ester component.

Electrochemical apparatus and method provide a source of electrons to a living organ in the process of transplantation. The organ, depleted of antioxidants, is placed into a vessel supplied with appropriate physiological solution and apparatus that create antioxidative environment.

Disclosed herein is a device in the form of a bung for insulating a container interior from the ambient environment, the bung comprising: a plurality of insulating segments; and one or more barriers for reflecting infrared radiation. Disclosed is: a method of preparing a shipping system for retaining a cryopreserved sample, the method comprising: loading a cryopreserved sample into a container such as a vacuum flask; and fitting the bung to the container to insulate the container interior from the ambient environment, and a method of cooling a container, such as a vacuum flask, for retaining cryopreserved samples to a desired temperature, the method comprising: cooling the container interior by pouring a cryogenic fluid such as liquid nitrogen into the container; and emptying the cryogenic fluid from the container, once the cooling has at least partially taken place.

According to an embodiment of the disclosure, a vial cap is configured for sealing attachment to a tube set and to a vial having a hollow interior configured for receiving and storing a liquid sample. The vial cap may comprise an axially extending cylindrical wall and a radially extending cap top disposed within the cylindrical wall, wherein the cap top has an upper surface and a lower surface. The vial cap may include at least two exterior tubes extending upwardly from the upper surface of the cap top, wherein each exterior tube defines a passageway configured to communicate with the tube set. The vial cap may further include at least two interior tubular structures extending downwardly from the lower surface of the cap top, wherein the at least two interior tubular structures each define a passageway configured to communicate with one of the exterior tubes and the hollow interior.
