Abstract: Provided herein are methods for miRNA profiling for the diagnosis, prognosis, and management of melanoma and differentiation of melanoma from nevi.

Abstract: A surgical robotic system includes at least one eye tracking system positioned detect the direction of at least one user's gaze. Input derived from the eye tracking system may be used to enter commands to the surgical robotic system depending on the directions of the gaze detected or other aspects of the gaze such as pupil dilation or speed of eye movement.

Abstract: Systems and methods using the systems of testing radio frequency receivers include a radio frequency receiver testing device that has a PIN switch adapted to receive a radio transmission, a thermal diode coupled to the PIN switch and controlling the amount of noise within the PIN switch, and a noise diode providing a stable noise source to the radio frequency receiver testing device.

Abstract: A supplement for improving one or more of joint pain, joint health, or inflammation in a healthy mammal. The supplement includes a type II collagen composition, where the type II collagen composition is present in the supplement in an amount sufficient to improve one or more of joint pain, joint health, joint mobility, or inflammation in a healthy mammal that is undergoing or that has undergone physical activity, as compared to the same mammal that has not been administered the supplement.

Abstract: The present disclosure is directed to processed animal food and/or treat that includes undenatured type II collagen. The undenatured type II collagen is introduced to the animal food and/or treat prior to processing, and at least 30% or more of the undenatured collagen remains undenatured in the after processing the animal food and/or treat.

Abstract: An ultrasound imaging scan head includes a fluid chamber including a gearless voice-coil motor therein. The voice-coil motor mechanism includes a rigid mechanical assembly, capable of moving with the fluid chamber, having one or more transducer elements and motor windings. Within the fluid chamber are motor magnets physically separated from the rigid mechanical assembly. The ultrasound imaging scan head further includes an inductive position sensor and internal bladder wherein the one or more transducer elements are capable of moving within the fluid chamber when a current is passed through the motor windings in a presence of a magnetic field generated by the one or more motor magnets.

Abstract: The position and orientation of an ultrasound probe is tracked in three dimensions to provide highly-accurate three-dimensional bone surface images that can be used for anatomical assessment and/or procedure guidance. The position and orientation of a therapy applicator can be tracked in three dimensions to provide feedback to align the projected path of the therapy applicator with a desired path for the therapy applicator or to provide feedback to align the potential therapy field of a therapy applicator with a target anatomical site. The three-dimensional bone surface images can be fit to a three-dimensional model of the anatomical site to provide or display additional information to the user to improve the accuracy of the anatomical assessment and/or procedure guidance.

Abstract: The present disclosure is directed to a composition or nutritional product containing a cannabinoid in combination with an adjuvant, such as a Type II collagen. The different nutraceutical agents are capable of synergistically working together to improve the health and well-being of a human or animal. For instance, the nutritional product can be used in many different applications, such as to treat joint discomfort and pain, and/or to improve muscular health.

Abstract: In some embodiments, a method comprises: obtaining a 2D ultrasound image of an imaged region of a subject, the imaged region comprising bone; identifying model template cross-sections of a 3D model of the bone corresponding to the 2D image at least in part by registering the 2D ultrasound image to the 3D model, wherein the model template cross-sections are defined prior to obtaining such 2D image, the model template cross-sections having size and shape representative of a population of potential subjects; identifying at least one location of at least one landmark feature of the bone in the 2D image based on results of the registration; and generating a visualization that includes: a visualization of the 2D image and a visualization of one of the identified cross-sections of the 3D model, wherein the visualization indicates the at least one location of the at least one landmark feature.

Abstract: Handheld ultrasound imaging devices for identification of target regions are generally described. Medical ultrasound is a popular medical imaging modality primarily used for diagnostic imaging of soft tissue but also for interventional procedures such as guidance of a needle or catheter placement. Examples include diagnostic imaging of organs, such cardiac or liver structures. Common interventional procedures that rely on ultrasound guidance are central line placement and guidance of nerve blocks, both of which are high volume procedures in certain hospital settings such as the intensive care unit (ICU). Handheld ultrasound imaging devices with integral display screens and improve portability are described, along with systems and methods for orienting displayed ultrasound images so as to improve their usefulness in guiding interventional procedures.
