Accommodating intraocular lenses including an optic having an anterior element and a posterior element defining an optic fluid chamber, wherein the optic is aspheric across all powers throughout accommodation or disaccommodation. Intraocular lenses, optionally accommodating, where an optic portion is centered with a midline of a height of the peripheral portion, the height measured in the anterior to posterior direction.

Disclosed are methods for inducing cardiomyogenic differentiation in cells that are competent for differentiation along the cardiomyogenic lineage such as certain unfractionated bone marrow mononuclear cells (BMMNCs). In some embodiments, the methods include contacting a plurality of unfractionated, density gradient-separated BMMNCs with a cardiomyocyte differentiation-inducing amount of a Wnt11 gene product for a time and under conditions sufficient to induce cardiomyocyte differentiation in at least a subset of the BMMNCs. Also provided are methods for treating an injury to cardiac tissue in a subject using cells that have been induced to differentiate along the cardiomyogenic lineage, recombinant host cells comprising an expression vector that encodes a Wnt11 polypeptide or a functional fragment thereof, and systems for inducing cardiomyogenic differentiation in a cultured cell.

A blood pressure can be obtained by supplying an external pressure to a portion of an artery. The external pressure is preferably between the systolic and diastolic pressure. An event which occurs at least once a cycle can then be identified. This event can be, for example, a peak in the arterial compliance that occurs at a transmural pressure approximately equal to zero. A pair of signals, one that is an arterial volume-indicating signal, and one that is an arterial pressure-indicating signal can be used to identify this event. Alternately, a small signal high-frequency exciter component can be placed upon the pressure or volume of the artery and detected to determine the time that the transmural pressure is equal to zero.

A cooler and methods of storing the cooler in a bag such as a purse are described herein. The cooler can have a strap allowing it to be used as a stand-alone device. The cooler can have securing devices such as magnets embedded within two pockets on a side wall of the cooler. The pockets can be located on the top half of the cooler to prevent tipping and are movable within the pockets so that the magnets can be positioned to avoid obstructions on the bag. The cooler magnets can be magnetically mated with magnets used with protective covers on the outside of the purse (zero purse modifications) or with magnets embedded within the purse wall.

An exemplary sterilization system includes a self-propelled robotic mobile platform for locating and eradicating infectious bacterial and virus strains on floors (and objects thereon), walls, cabinets, angled structures, etc., using one or more ultraviolet light sources. A controller allows the system to adjust the quantity of ultraviolet light received by a surface by, for example, changing the intensity of energy input to a ultraviolet light source, changing a distance between a ultraviolet light source and a surface being irradiated, changing the speed/movement of the mobile platform to affect time of exposure, and/or by returning to contaminated areas for additional passes. The mobile platform may include a sensor capable of detecting fluorescence of biological contaminants irradiated with ultraviolet light to locate contaminated areas. The system is thus capable of “seek and destroy” functionality by navigating towards contaminated areas and irradiating those areas with ultraviolet light accordingly.

A measurement device for generating an arterial volume-indicative signal includes an exciter and a detector. The exciter is adapted to receive an oscillating signal and generate a pressure wave based at least in part on the oscillating signal on the artery at a measurement site on a patient. The pressure wave includes a frequency. The detector is placed sufficiently near the measurement site to detect a volumetric signal indicative of arterial volume of the patient.

The present invention provides a motorized vehicle of the type having a chassis supported by a set of wheels, at least one of which being driven by a motor. The vehicle is operable to simulate impaired driving. In particular, a vehicle control system is provided that controls at least one aspect of vehicle operation in response to an operator input intended to produce an expected vehicular response. An impairment simulator is provided that is operable in a first mode whereby the vehicle control system produces the expected vehicular response, and a second mode whereby the vehicle control system produces a response inconsistent with the expected vehicular response.
