Method and apparatus to prepare cardiac organoids in a bioreactor system
A bioreactor system for preparing a cardiac organoid chamber and for subsequent testing thereof is described herein and shown in the exemplary drawing figures. The bioreactor system includes a first vessel having a hollow interior and an open top. A first cover is mated with the open top of the first vessel. The first cover has a first opening formed therein. The system further includes a cannula having a lumen that extends from an open first end to an open second end. The cannula is disposed within the first opening of the first cover such that a portion of the cannula lies below the first cover and for insertion into the hollow interior of the first vessel. A porous ring is coupled to the cannula at or proximate the open second end thereof. The system also includes a balloon catheter having an inflatable balloon at a distal end of a catheter shaft. The balloon catheter is adapted to pass through the lumen of the cannula when the balloon is in a deflated state. The balloon catheter is axially adjustable within the lumen to allow the balloon in an inflated state to be disposed adjacent: (1) the open second end of the cannula; and (2) the porous ring for preparing the cardiac organoid chamber about the inflated balloon and porous ring. The cannula and porous ring construction and combination allows for the balloon to be deflated and removed from the lumen of the cannula while the engineered cardiac organoid chamber remains attached to the porous ring. This permits the testing of organoid pump function, such as organoid pressure and volume characteristics, without having to transfer the engineered cardiac organoid from one tool (e.g., an incubation tool) to another tool (e.g., a functional testing apparatus).
Culture system and culture method
A culture system comprises: a preparatory culture vessel and a main culture vessel that accommodate cells and a solution; a main stage that holds the preparatory culture vessel and the main culture vessel; a connecting tube that connects the culture vessels; a valve that opens and closes the connecting tube; and a rotating mechanism that rotates the main stage and imparts a height difference between the culture vessels to transfer the cells and solution by dropping between the culture vessels.
Biomanufacturing suite and methods for large-scale production of cells, viruses, and biomolecules
The present invention provides a production module for large-scale production of cells and/or cell-derived products such as antibodies or virus; a production suite comprising a plurality of functionally connected production modules of the invention; and a method for large-scale production of cells and/or cell-derived products using the production modules and/or production suites of the invention.
Increased Homogeneity of Mycological Biopolymer Grown into Void Space
The method of growing a biopolymer material employs incubation of a growth media comprised of nutritive substrate and a fungus in containers that are placed in a closed incubation chamber with air flows passed over each container while the chamber is maintained with a predetermined environment of humidity, temperature, carbon dioxide and oxygen. The air flows may be directed parallel or perpendicularly to the surfaces of the growth media.
FOAM MITIGATION IN BIOREACTORS USING ULTRASOUND
A bioreactor for culturing of microorganisms or cells comprising: a casing defining an interior space of the bioreactor, wherein said interior space is configured to receive and hold a culture medium with microbial or cellular liquid cultures; and at least one coupling element provided on the casing for coupling with a foam mitigation device for mitigation of foam built-up in the interior space of the bioreactor during use of the bioreactor for culturing of microorganisms or cells; wherein the coupling element is configured to allow ultrasonic waves generated by the foam mitigation device act upon foam built-up in the interior space of the bioreactor.
Connection Clamping Device
A connection clamping device (21; 61; 81; 131; 151) arranged for securing a flexible tube (1) to a barbed end (5b) of a tube connector (5), whereby the barbed end (5b) comprises a barb (9) and the tube connector during connection is arranged to protrude into an end of the flexible tube (1), characterized in that said connection clamping device comprises two sections (23a, 23b) which, during connection when the tube connector protrudes into an end of the flexible tube, are arranged to be connected and locked to each other by a locking mechanism (33a,33b,34a,34b; 63a, 63b, 64a, 64b) around the tube connector (5) and the flexible tube (1), such that the flexible tube (1) is compressed against the tube connector (5) by a rib (41a, 41b) provided on the inner circumference of the connection clamping device.
Salt management system for portable renewable energy microgeneration system
A renewable energy microgeneration apparatus is disclosed that includes a mixing tank that mixes waste with a liquid, a buffer tank that receives and pre-warms the mixed waste, a pasteurization tank that pasteurizes on the pre-warmed mixed waste, a digestion tank that performs anaerobic digestion on the pasteurized waste, a de-watering device that separates liquid digestate and removes salt from the liquid, sensors that measure salinity and biogas quality, and a controller. The controller causes the transfer of digestate from the digestion tank to the pasteurization tank to the dewatering device, causes the de-watering device to separate the liquid and remove the salt from the liquid, monitors the salinity of the liquid and the quality of biogas using the sensors, and causes the mixing of the liquid with the waste and adjusts the feed rate of the waste to reduce the salinity of the waste and increase methane production.
FRANCISELLA GLYCOCONJUGATE VACCINES
The disclosure relates to a glycoconjugate vaccine conferring protection against Francisella tularensis infections and a method to manufacture a glycoconjugate antigen.
Rupture Disks for Bioreactors and Methods of Using Same
A rupture disk includes a body including an internal wall extending from a first end of the body to a second end of the body. The internal wall defines an opening extending through the body. In some embodiments, the body further includes an internal flange formed on the internal wall, and the internal flange has a stepped surface. A rupture membrane is positioned within the body, and secured, for example, by cold welding. The rupture membrane may be secured to the stepped surface. The rupture membrane is positioned within the body such that the rupture membrane does not extend beyond the first end of the body. A process system including the rupture disk is also provided. A method of maintaining a process system that includes the rupture disk is also provided.
Methods and apparatus for gas stream mass transfer with a liquid
A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A tube has a first end and an opposing second end, the first end of the tube being disposed within the compartment of the container. A nozzle is disposed within the compartment of the container and has at least one outlet, the nozzle being coupled with the tube so that a gas can be passed through the tube and out the at least one outlet of the nozzle. The nozzle is sufficiently buoyant so that when a fluid is disposed within the compartment of the container, the nozzle floats on the fluid.
