Abstract: An implantable device for controlling electrical conditions of body tissue. A feedback sense electrode and a compensation electrode are positioned proximal to the tissue to make electrical contact with the tissue. A feedback amplifier is referenced to ground, and takes as an input a feedback signal from the feedback sense electrode. The output of the feedback amplifier is connected to the compensation electrode. The feedback amplifier thus drives the neural tissue via the compensation electrode in a feedback arrangement which seeks to drive the feedback signal to ground, or other desired electrical value.

Abstract: At least one array of LEDs (e.g., in a flip chip configuration) is supported by a substrate having a light extraction surface overlaid with at least one lumiphoric material. Light segregation elements registered with gaps between LEDs are configured to reduce interaction between emissions of different LEDs and/or lumiphoric material regions to reduce scattering and/or optical crosstalk, thereby preserving pixel-like resolution of the resulting emissions. Light segregation elements may be formed by mechanical sawing or etching to define grooves or recesses in a substrate, and filling the grooves or recesses with light-reflective or light-absorptive material. Light segregation elements external to a substrate may be defined by photolithographic patterning and etching of a sacrificial material, and/or by 3D printing.

The patient movement detector can, for example, output a fall warning alarm, a bedsore warning alarm, patient location information, and walk test scores.

Abstract: A method for measuring a neural response to a stimulus. Measurement circuitry is settled prior to a stimulus, by connecting a sense electrode to the measurement circuitry to allow the measurement circuitry to settle towards a bio-electrically defined steady state. Charge is recovered on stimulus electrodes by short circuiting the stimulus electrodes to each other. An electrical stimulus is then applied from the stimulus electrodes to neural tissue, while keeping the sense electrode disconnected from the measurement circuitry. After the stimulus, a delay is imposed during which the stimulus electrodes are open circuited and the sense electrode is disconnected from the measurement circuitry and from the stimulus electrodes. After the delay, a neural response signal present at the sense electrode is measured by connecting the sense electrode to the measurement circuitry.

In some aspects, a light extraction surface of each substrate portion includes protruding features and light extraction surface recesses. Lateral borders between different pixels are aligned with selected light extraction surface recesses. In some aspects, selected light extraction surface recesses extend through an entire thickness of the substrate. Other technical benefits may additionally or alternatively be achieved.

Abstract: Provided are methods and compositions for treating an individual who has a medulloblastoma. Methods for treating an individual who has a medulloblastoma tumor can include a step of administering to the individual, at a dose sufficient to reduce the size and/or growth rate of the medulloblastoma tumor, a composition that includes a casein kinase II (CK2) inhibitor (e.g., a CK2-selective inhibitor such as CX-4945). In some cases, the medulloblastoma tumor is a hedgehog-dependent medulloblastoma tumor. In some cases, the medulloblastoma tumor is a hedgehog-independent medulloblastoma tumor. In some cases, the medulloblastoma tumor is smoothened inhibitor-resistant (SMO inhibitor-resistant). In some cases, the medulloblastoma is resistant to treatment with 4,5,6,7-tetrabromo-2H-benzotriazole (TBB). In some cases, the dose is sufficient to cause long term regression of the medulloblastoma tumor, and in some cases, the dose is sufficient to increase the chance of survival of the individual.
