Abstract: The disclosed technology relates generally to a method and system for an improved lighting apparatus compatible with imaging small specimens for viewing or photographic purposes. In certain embodiments, the disclosed technology provides an apparatus for projecting light on specimens from opposing light sources at varying distances and angles. In certain embodiments, the apparatus includes an elongated stem that allows the light sources to be repositioned quickly, easily, and accurately. The elongated stem may be flexible and may be used in conjunction with a positioning system, such as a rack and pinion system, thereby allowing precise movement of the light sources.

Abstract: The invention is directed to methods and compositions for increasing a growth characteristic of a plant, increasing nutrient use efficiency of a plant, or improving a plant's ability to overcome stress comprising applying a composition comprising ketosuccinamate, a derivative thereof, or a salt thereof, to the plant or to a propagation material of the plant.

Abstract: Embodiments of the invention provide methods of obtaining continuous cardiac information from a mammal. First, attach a self-contained, wearable, portable continuous cardiac monitor to the mammal to create a chamber containing electrodes used to detect cardiac signals from the mammal. Next, continuously detect without analyzing the cardiac signals from the mammal for at least 24 hours. Next, store information related to substantially all detected cardiac signals in the cardiac monitor.

Abstract: Embodiments of the present invention provide a method of analyzing cardiac information by collecting a plurality of self-contained, wearable, portable cardiac monitors each of the cardiac monitors electronically storing at least 24 hours of continuously detected and unanalyzed cardiac signals from a mammal. Next, retrieving cardiac information stored in each of the plurality of self-contained portable cardiac monitors. Next, forwarding retrieved cardiac information.

Abstract: One embodiment of the invention is a cardiac monitor having a housing; a plurality of electrodes within and extending from the housing; a state machine within the housing configured to digitialize and store in memory signals from the plurality of electrodes; a sealing surface and an adhesive on the sealing surface configured to form a watertight perimeter around the plurality of electrodes when the housing is affixed to a mammal.

Abstract: A device completely disposable within a bodily lumen of a patient and for controlling flow through the bodily lumen having a device body having a proximal end, a distal end and a device lumen within the device body extending from the proximal end to the distal end and a fixation element extending from the outer wall of device body adapted and configured to engage with the wall of the bodily lumen. The device body is adapted and configured to move from a position where the device lumen blocks flow through the bodily lumen to a position where the device lumen allows flow through the bodily lumen. In other configurations, there are one or more valves within the device lumen adapted and configured to move between a position to block flow through the bodily lumen and a position to allow flow through the bodily lumen.

Abstract: The subject invention concerns vascular prosthetic devices and methods for ascending aorta and/or valve replacement in humans and animals. In one embodiment, a device of the invention includes a vessel-like structure having a first end adapted for surgical attachment to a left ventricle, a second end adapted for surgical attachment to an aorta, and, interposed between the first and second ends, a sinus portion configured in the shape of the sinuses of Valsalva in a human aortic valve.

Abstract: Neurological disorders, such as migraine and addiction to smoking tobacco, are treated by the administration of an effective amount of nicotine, preferably in a water solution of nicotine processed to diminish the odor, taste, and smell of nicotine.

Abstract: Continuous single-step processes for producing higher molecular weight ketones are disclosed that involve a liquid-phase crossed condensation of an aldehyde with a ketone in the presence of a hydrogenation catalyst and a small amount of a catalyst comprising a concentrated hydroxide or alkoxide of an alkali-metal (from Group 1 or Group IA of the Periodic Table of the Elements) or alkali-earth metal (from Group 2, or Group IIA of the Periodic Table of the Elements), wherein the amount of water provided to the reaction mixture, or reaction zone, is relatively low, with respect to the total initial weight of the reaction mixture. The reaction may be carried out in the absence of solubilizing agents or phase transfer agents. The product mixture is largely free of by-products resulting from further condensation reactions of the desired ketone product or intermediates, and free of the self-condensation products of the reactant aldehyde, that are afterward difficult to remove from the reaction mixture.
