The present disclosure relates to a process that comprises, in at least one embodiment: accessing a camera via an application; prompting a user to induce blanching for a time period of 10 seconds; processing information from the camera to automatically detect one or more fingernails for each of the one or more fingers; accessing video data from the camera; computing a capillary refill time; causing a display screen to display the capillary refill time; and transmitting the capillary refill time to a computing device.

Capillary refill image processing systems and processes

A smartphone-based hemoglobin (Hgb) assessment application quantitatively analyzes pallor in patient-sourced photos using image analysis algorithms to enable a noninvasive, accurate quantitative smartphone app for detecting anemia. A user takes a photo of his/her fingernail beds using the app and receives an accurate displayed Hgb level. Since fingernails do not contain melanocytes, the primary source of color of these anatomical features is blood Hgb. At the same time, quality control software minimizes the impact of common fingernail irregularities (e.g. leukonychia and camera flash reflection) on Hgb level measurement. Metadata recorded upon capturing the image is leveraged for determining a users' Hgb level thereby eliminating the need for external equipment. A personalized calibration of image data with measured Hgb levels improves the accuracy of the application.

Systems and methods for quantitative diagnosis of anemia

The systems and methods are directed to leveraging the channel geometry and configuration to overcome diffusion limitations of current transduction systems. The methods may include a method of transducing target cells using a device. The device may include at least one continuous channel. The method may include delivering target cells and viral vectors into a transduction region of the channel. After transducing for some incubation time, a flushing solution may be delivered. The method may include collecting transduced cells after the transducing incubation time and the delivering of the flushing solution.

Methods, devices and systems for enhanced transduction efficiency

This disclosure relates to microcapsule particles for targeted delivery of drugs. In certain embodiments, the particles comprise polyelectrolyte polymers, e.g., layers of anionic polymers and cationic polymers. In certain embodiments, the particles have a fibrinogen coating. In certain embodiments, the particles contain a polysaccharide core and/or a polysaccharide coating encapsulating drugs, proteins, clotting agents, coagulation factors, or anticoagulants. In certain embodiments, this disclosure contemplates methods of using particles disclosed herein to prevent or reduce onset of or duration of bleeding. In certain embodiments, this disclosure contemplates methods of using particles disclosed herein to prevent or reduce onset of blood clotting.

Particles for targeted delivery and uses in managing bleeding or blood clotting

An imaging system consisting of a cell-phone with camera as the detection part of an optical train which includes other components. Optionally, an illumination system to create controlled contrast in the sample. Uses include but are not limited to disease diagnosis, symptom analysis, and post-procedure monitoring, and other applications to humans, animals, and plants.

High numerical aperture telemicroscopy apparatus

An improved system and methods for enhancing the imaging of cameras included with wireless mobile devices, such as cellular phone or tablets. The imaging system includes a releasable optical attachment for imaging skin surfaces and cavities of the body. The releasable optical attachment comprises optical enhancement elements such as magnifying lenses, illumination diverting elements, and filters. Images can be viewed and analyzed on the mobile device, or transmitted to another location/device for analysis by a person or software. The results can be used to provide diagnosis, or for a variety of other applications including image comparison over time and product recommendations.

Cellscope apparatus and methods for imaging

Diagnostic kits and methods configured to rapidly and non-invasively determine physiologic levels of hemoglobin. A diagnostic kit may include a chamber pre-filled with an indicator, the indicator solution including a tetramethylbenzidine (TMB) solution, the indicator being configured to change color; a collection device configured to collect a test sample from a subject. The kit may also include a hemoglobin physiologic level identifier legend, the legend indicating 1) at least one color of the indicator and 2) a physiologic level and/or range of the hemoglobin and/or disease state associated with the color.

Kits and methods for determining physiologic level(s) and/or range(s) of hemoglobin and/or disease state

A device may be configured to allow individual measuring of at least one property of at least one cell, such as measuring a contraction force of a platelet. The device may include a plurality of wells. Each well may include a hydrogel layer, the hydrogel layer including a hydrogel having a top surface that includes a pattern of cell interaction regions. The wells may differ in stiffness properties of the hydrogel and/or biochemical conditions. Each cell interaction region may include a group of at least two cell interaction sites. The spacing between each cell interaction region may be greater than a spacing between the at least two cell interaction sites of each cell interaction region. In this way, cell-cell interactions may be reduced and thereby increasing number of individual cells capable of being measured.

Devices for determining cell force properties and methods of manufacturing the devices

Devices and methods relate to inducing or promoting hemostasis. The hemostasis device may include a support layer having a first surface and an opposing second surface. The device may include a layer, the layer disposed on the first surface. The layer may include a target surface configured to contact a target site. The layer may include a monolayer of about 100% graphene or may include laser-reduced graphene oxide. The device may include a sensor configured to measure a level of hemostasis of the target site. The methods relate to a method of manufacturing a hemostatic device including a monolayer of graphene or a layer of laser-reduced graphene oxide.
