摘要:
A device for receiving implanted biological material includes a porous outer wall defining an inner space, a fluid manifold assembly for selectively infusing at least one of immunosuppressive and growth factor media to said space, and a pump structure operatively coupled to the manifold assembly. The device may comprise an additional plunger body for being disposed in said space and so as to define a peripheral gap between the plunger and the perforated wall of the device.

A perifusion device includes at least one sample container for cells, the sample container having an inlet and an outlet. The container receives test liquid through the inlet and discharges the liquid through the outlet. A receptacle housing has a plurality of receptacles for receiving fluid from the outlet of the sample container. A drive is connected to the receptacle housing for moving the receptacle housing such that liquid samples are collected sequentially from the outlet of the sample containers. A computer can be provided to control movement of the receptacle housing at predetermined times, and to record data identifying liquid samples in the receptacles. The test liquid includes at least one stimuli for the cells, which can be the presence, absence, or concentration of a compound in the liquid, or a physical property of the liquid such as temperature. The liquid collected in the receptacles is analyzed to determine the response of the cells to the stimuli.

A container for shipping items in an aircraft includes a shipping compartment and an expandable chamber for receiving gas from the shipping compartment. At least one conduit connects the expandable chamber to the shipping department so as to permit the flow of gas therebetween. A method for shipping items in an aircraft is also disclosed.
摘要:
A cell population or subpopulation enrichment procedure for separating undesired populations or subpopulations from a biological sample utilizing relatively heavy, dense particles and gravity sedimentation. The particles have one or more reactants bound thereto which are specific to and will bind with the selected population or subpopulation to be eliminated from the sample. The particles preferably are mixed with the sample by repeatedly causing the particles to settle through a substantial portion of the sample to bind to the selected population. The particles with the bound selected population to be eliminated then are allowed to preferentially settle in the sample and the supernatant including the enriched population or subpopulation is separated from the particles with the population to be eliminated bound thereto. The enriched population supernatant can then be analyzed, utilized as is, have other populations or subpopulations removed or have additional amounts of remaining cells of the previously eliminated populations removed in additional steps.

A composite for delivering extended-release of oxygen is disclosed. The composite can include a biocompatible polymeric support having a plurality of solid peroxide particles suspended therein. The polymer support can exhibit an oxygen tension value of at least 40 mmHg for a period of 14 days. The weight ratio of biocompatible polymeric support to solid peroxide particles can range from 1:1 to 99:1. Also disclosed is a method of using the composite to deliver oxygen to cells in both in vivo and in vitro environments.
摘要:
Azo dyes and suramin-related small molecules are effective in inhibiting the CD40/CD154 protein-protein interaction, an important co-stimulatory interaction involved in the activation of immune responses mediated by T- and B-cells. The compounds were found to be active as indicated by their IC50 values both in a cell-free binding assay and in the inhibition of CD154-induced B-cell proliferation assay. The compounds may be used as therapeutic compounds for treatment of diseases and disorders related to immune or inflammatory responses. Methods of inhibiting the CD40/CD154 protein-protein interaction and treating diseases and disorders related to immune or inflammatory responses are described.
摘要:
This present invention relates to a system, method, and apparatus for an authorized approver (AA) to receive and transmit information to contacts of an end user or others. The authorized approvers may receive, for example, voice, data or video or a combination thereof from the end user. Said authorized approver may view the received information on a back-end server or on a telecommunications device including but not limited to a mobile device or mobile internet device. The authorized approvers may retransmit the end user data to one or more contacts of the end user. Before such retransmission, the authorized approver, may amend, summarize, modify, tag, or otherwise edit the end user information before sending it on to the end user contacts.

This present invention relates to a system, method and apparatus for scientists and researchers and others to capture, secure, share, retrieve and search captured data. Said system and method is able to: fully-integrate hardware and software, required to seamlessly capture data inputs; combine edit and display functions from devices into one single edit and display platform; compile captured inputs from devices into text-searchable and tag-able data that can be displayed, edited and searched on one platform; compile captured inputs from devices into text-searchable and tag-able data that can be searchable by using free-text search, advanced search modules, or a combination thereof; provide advanced search modules that can search based on embedded text in files, tags tied to images or files, parallel image search and other intelligent parameter-based search formats; and can be provided as a hosted application, available via a wire line or wireless on-demand service, also referred to as Software as a Service (SaaS) delivery method.
摘要:
An organ preservation container includes a gas impermeable housing for containing an organ. At least two liquids having different densities and forming a liquid-liquid interface are also contained in the housing. A closure for hermetically sealing the housing is provided. A structure is provided within the housing for engaging the organ and for maintaining a portion of the organ at the liquid-liquid interface such that the organ will be maintained partially in both of the liquids. A method for preserving the organ is also described.
