The present disclosure relates to methods of collecting and testing bacteria containing samples from within the gastrointestinal (GI) tract of a subject. The methods may include disposing an ingestible device in the GI tract, collecting a bacteria-containing sample from the GI tract, selectively lysing eukaryotic cells in the sample by combining the sample with a dried reagent, exposing bacteria in the sample to resazurin in the ingestible device to produce resorufin, emitting light from the ingestible device, the emitted light being filtered through an optical filter to control for scatter so that the light interacts with the resorufin to produce fluorescence, and measuring a total fluorescence from the resorufin; or a rate of change of fluorescence from the resorufin as a function of time within the GI tract of the subject; and correlating the measured parameter to a number of viable bacterial cells in the sample.

An excrement management system according to an embodiment includes: a closet bowl in which a bowl part for receiving excrement is formed; a light emitting unit configured to emit light toward an inner part of the closet bowl; a light receiving unit comprising an image sensor configured to receive light; a cloud server and an edge server configured to analyze light reception data received by the light receiving unit; a first communication device configured to transmit the light reception data to the cloud server; and a second communication device configured to transmit the light reception data to the edge server. The cloud server analyzes the light reception data to determine a characteristic of excrement, and the edge server analyzes the light reception data to determine whether to transmit the light reception data to the cloud server by the first communication device.

Provided are systems for grouping users who have chosen to participate into one of a plurality of menstrual cycle groups based on data provided by and/or collected from those users. In some examples, a wearable computing device can include one or more sensors that can measure one or more physiological signals associated with the user. Based on the physiological signals gathered from the one or more sensors, the wearable computing device can determine biometric data for one or more users. Furthermore, the wearable computing device can enable a user to submit information about their menstrual cycle (e.g., via an interactive touch screen). These factors can be used to automatically determine some menstrual cycle data for a user.

A device and a method for a lavage-type introduction of a stool transplant or of another, local or topically effective substance through the anus into the colon of a patient, wherein the substance to be introduced is flushed also into the upper parts of the colon of the patient in a torrent-like manner through correspondingly large-lumen catheters; said device comprises an ano-rectal placed head part remaining inside the patient from the beginning until the end of the application and a system of exchangeable bags, which are connectable to the head part, whereby two different types of bags can be applied, one of which is designed for the cleaning lavage, while the another is designed for the introduction of a substance or a transplant.

A method for using saliva to measure at least one substance or physiological parameter of a human or animal subject may involve inserting a first end of a sensor into a handheld saliva testing device. The method may also involve receiving saliva from the subject on a second end of the sensor, moving the saliva from the second end of the sensor to the first end, and processing the saliva with the handheld saliva testing device to provide initial saliva data related to the at least one substance or physiological parameter of the subject. In some embodiments, the sensor remains inserted in the handheld device while the subject deposits saliva on the opposite, free end of the sensor.

Disclosed herein are a group of gastric cancer VOC markers in saliva and an application thereof in the preparation of a diagnostic reagent of gastric cancer. The markers are a combination of compounds selected from the group consisting of acetaldehyde, 2-methylbutyraldehyde, isopropanol, hexanal, n-butanol, cineole, nonanal, menthone, 2-ethylhexanol, menthol, anethole and dodecanol. The diagnostic reagent is used for detecting the contents of the marker in a saliva sample of a subject to perform the diagnosis of gastric cancer.

An estimation system includes: a first sensor that detects a first amount of activity that is an amount of activity of a subject in a room; a second sensor that detects a second amount of activity that is an amount of activity of the subject on a bed in the room; and an estimation device that estimates at least one of a position and an action of the subject in association with a position in the room based on the first amount of activity detected by the first sensor and the second amount of activity detected by the second sensor, and outputs an estimation result obtained from the estimation. The first sensor and the second sensor are sensors other than two-dimensional image sensors.

An improved biopsy tray includes a container having bottom surface and continuous perimeter wall extending upward therefrom to form a cleaning zone which is sufficient to hold an adequate amount of fluid for cleaning a biopsy forceps, and at least one specimen bottle receiving receptacle adjacent the perimeter wall to receive and retain a specimen bottle. A method of obtaining a biopsy specimen includes employing the tray of the invention.

The present invention relates in general to the improved containment of biological fluids. In particular, a method and apparatus for collection and preservation of fluid samples in accordance with the present invention results in collection of semen having improved viability both at the time of collection and after storage. The disclosed apparatus support a wide variety of applications for containment of biological fluids related to human and veterinary medicine including, but not limited to, human reproductive medicine and animal husbandry.

The present invention teaches a method of predicting the potential for manifestation of various medical conditions by analyzing human placenta comprising and including determining the need for early monitoring, intervention or potential treatment for medical conditions likely to manifest as a child grows older and investigating the potential for various medical conditions. The method includes selecting and identifying a sample of the placenta to analyze by algorithms and preparing the sample to be analyzed. The sample is captured by obtaining a three-dimensional digital image of the chorionic surface of the sample by a selected capturing device. The physician corrects for errors in the digital image and loads the data into a computer for analysis. The digital image data is analyzed using algorithms to determine the vascular structure of the placenta, which is interpreted and analyzed to determine the potential for manifestation of various medical conditions.
