Abstract: A latch assembly for a door having a door body mounted on a door frame includes a retainer movable between a latching position and a non-latching position and configured, in the latching position, to retain the door body in a closed position, and to permit the door body to move with respect to the door frame in the non-latching position to an open position. An actuator is selectively moveable to change the retainer from the latching position to a non-latching position. A linkage is configured to move the retainer in a latching direction toward the latching position and in an unlatching direction toward the non-latching position responsive to actuation of the actuator. A crank is operatively connected to the actuator and linkage and configured to move the retainer toward the latching position as the retainer approaches the latching position.

Abstract: Some embodiments provide a method for magnetic resonance imaging of polysaccharide molecules, that includes providing a magnetic field that is sufficiently homogeneous over an imaging volume, generating a spatial encoding in the magnetic field, and acquiring one or more water proton signal intensity measurements at each of multiple voxels within the imaging volume.

Abstract: A method of assessing the brain lymphatic or glymphatic system and the glucose transporter function on blood-cerebrospinal fluid barrier (BCSFB) of a subject using D-glucose or a D-glucose analog. A spatial map is generated of water MR signals that are sensitized to changes in D-glucose or a D-glucose analog in cerebrospinal fluid (CSF) of the subject. The spatial map is observed at one or more time points before, one or more time points during, and one or more time points after, raising the blood level of the D-glucose or a D-glucose analog in the subject CSF. A difference is detected between the MR signals of the spatial map before, during, and after raising the blood level of D-glucose or a D-glucose analog. A physiological parameter associated with the brain lymphatic or glymphatic system and the glucose transporter function on BCSFB of the subject is ascertained based on the detected difference.
