The present disclosure provides materials and methods for the delivery of therapeutic nucleic cells (and imaging agents) to tissues.

In one aspect, the present disclosure provides a method for identifying treatment targets relating to tumors. In another aspect, the present disclosure provides a method for identifying biomarkers and molecular features of normal and cancer cells.

A discrimination system that forms a fluid column and interrogates objects within the fluid column with an excitation source. An optical arrangement collects output electromagnetic radiation emanating from the excited objects disposed within the fluid column and directs the output electromagnetic radiation to a detector. An analyzer reduces the positional dependency of the detected intensity by normalizing the value based on the position of each object.

The invention enables efficient, rapid, and sensitive enumeration of living cells by detecting microscopic colonies derived from in situ cell division using large area imaging. Microbial enumeration tests based on the invention address an important problem in clinical and industrial microbiology—the long time needed for detection in traditional tests—while retaining key advantages of the traditional methods based on microbial culture. Embodiments of the invention include non-destructive aseptic methods for detecting cellular microcolonies without labeling reagents. These methods allow for the generation of pure cultures which can be used for microbial identification and determination of antimicrobial resistance.

Disclosed are nanoparticle compositions comprising nanoparticles prepared from denatured, cross-linked albumin and a therapeutic agent for treating a neutrophil-mediated inflammation, and methods of treating neutrophil-mediated inflammation using the compositions.

This disclosure provides a new phagocytosis assay to test the function of RPE cells and photoreceptor progenitors using a pH sensitive fluorescent label.

Embodiments of the current disclosure are directed to systems, methods and apparatus for evaluating single cell secretion profiles. In some embodiments, the apparatus may be configured to analyze substances expressed by a biological cell and may include a first compressible substrate, and a second substrate configured for removable sealing attachment with the first substrate. In some embodiments, upon attachment of the second substrate with the first substrate, an assembly is formed such that the open side of the plurality of chambers are covered by the second substrate, and a portion of each of the plurality of capture areas are exposed in each of the chambers.

The present invention provides a method of measuring the quality of therapeutic cells through real-time glutathione monitoring.

A pharmaceutical preparation comprising ⊖A2-73 substantially free of A2-73. This invention further includes a method treating Alzeheimer's disease in a subject in need of such treatment by the method of administering a therapeutically effective amount of ⊖A2-73 substantially free of A2-73.

This invention yet further includes a method of classifying cells as to sigma receptor type by the method of exposing said cells to a detectable amount of ⊖A2-73 substantially free of A2-73 and determining the level of sigma receptor binding.

A well for electrically stimulating at least one cell. The well includes a bottom portion and comprises an adaptive electrode arrangement for introducing an electric field into the well. The adaptive electrode arrangement includes a pair of electrodes disposed within the well. Each electrode of the pair of electrodes has a distal end and is independently and axially displaceable relative to the other electrode and the bottom portion of the well. The distal end of each electrode of the pair of electrodes is in contact with the bottom portion of the well, ensuring a uniform and constant electric field is applied within the well.
