Abstract: A medical device may include an elongated body having a distal elongated body portion and a central longitudinal axis. The medical device may include a balloon positioned along the distal elongated body portion. The balloon may be configured to receive a fluid to inflate the balloon such that an exterior balloon surface contacts a calcified lesion within a patient's vasculature. The medical device may include one or more pressure wave emitters positioned along the central longitudinal axis of the elongated body. The one or more pressure wave emitters may be configured to propagate at least one pressure wave through the fluid to fragment the calcified lesion. At least one pressure wave emitter may include an optical fiber configured to transmit laser energy into the balloon. The laser energy may be configured to create a cavitation bubble in the fluid.

Abstract: Lettuce (Lactuca sativa) plants exhibiting resistance to downy mildew disease caused by Bremia lactucae are provided, together with methods of producing, identifying, or selecting plants or germplasm with a downy mildew resistance phenotype. Such plants include lettuce plants comprising introgressed genomic regions conferring pest resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed loci, are further provided.

Abstract: Methods for treatment and prevention of Potexvirus disease in plants are provided. Further provided are compositions for treatment or prevention of Potexvirus disease in plants, and methods for reducing expression of a Potexvirus gene and for identifying polynucleotides useful in modulating gene expression in plant viruses.

Abstract: The present invention provides gene targets, constructs and methods for the genetic control of plant disease caused by multiple plant viruses. The present invention relates to achieving a plant protective effect through the identification of target coding sequences and the use of recombinant DNA technologies for post-transcriptionally repressing or inhibiting expression of the target coding sequences of plant-parasitic viruses. Protein-expression based approaches may also be utilized to augment phenotype resistance. Thus, transcription of a single transgenic event comprising one or more plant expression cassettes can allow for broad spectrum resistance of a plant to multiple plant viral strains and species among the geminiviruses, tospoviruses, and potexviruses.

Abstract: A through-air device includes a permeable roll having a hollow interior and mounted for rotation about a longitudinal axis. At least one divider is located in the hollow interior so as to define a plurality of roll channels within the roll, the roll channels being positioned side-by-side along the longitudinal axis. A first housing bounds a first portion of the roll, and a second housing bounds a second portion of the roll. At least one partition is located in the second housing so as to define a plurality of housing channels within the second housing. Each one of the housing channels is aligned with a corresponding one of the roll channels. The device further includes structure for individually controlling airflow through each pair of corresponding roll channels and housing channels.

Abstract: Apparatus for determining the physical uniformity of a charged drum surface wherein current signals are induced in sensing electrodes in response to variation in drum surface charge. The sensing electrodes are on a detector assembly which is movable toward the drum for inspection of the surface and movable away from the drum after inspection when the drum is to be ejected from the apparatus. The detector assembly is movable through another degree of freedom to accommodate irregularities in drum geometry encountered during rotation thereof. The detector assembly also is provided with structure for maintaining a predetermined spacing of the sensing electrodes from the drum surface during relative movement therebetween. The drum is received, held, and rotated by co-operation between a drum retention assembly and a drum clamping mechanism.
