    Notes: Laser irradiation of organometallic palladium compounds with an argon ion laser at 351 nm is used to selectively deposit catalytic amounts of palladium on polyimide. Subsequent immersion of the irradiated samples in an electroless copper solution results in copper deposition. Since a few monolayers of palladium are sufficient to catalyze the electroless copper process, fast writing speeds of several centimeters per second are obtained.

    Notes: The effect of cigarette smoking and its active component, nicotine, on the gastric emptying of solid food was assessed in a randomized double-blind crossover design. Ten regular smokers were studied after a 6 h fast and least 18 h after their last cigarette. Subjects smoked a total of three high (1.91 mg) or low (0.17 mg) nicotine cigarettes, before and after a technetium-labelled solid meal and were scanned by gamma camera periodically over a 2-h period. All calculations of gastric emptying revealed a significant delay after smoking high versus low nicotine cigarettes in: mean per cent isotope remaining in the stomach at each measurement point from 90–120 min; amount of meal remaining in the stomach at 2 h; and mean time at which 50% of the meal had emptied (T1/2). Delay in gastric emptying was significantly correlated with increase in serum nicotine concentration on the high nicotine day.

    Notes: Abstract A numerical integration technique utilizing a point source Green's function is introduced to analyze the wave behavior in transversely isotropic-type anisotropic media allowing us to make fast and accurate computations of the acoustic field. The centrifugally cast stainless steel (CCSS) used in nuclear power plants is chosen as a sample medium because of its columnar grain character leading to material anisotropy. A representative number of field profiles are computed and plotted to illustrate the quasi-longitudinal, quasi-transverse, and horizontally-polarized shear wave propagation in a transversely-isotropic medium. Phenomena such as beam skewing, beam splitting, beam focusing, unsymmetrical beams, and other anisotropic effects, some of which are already known from earlier experimental observations, emerge as a computational result of the introduced technique.

    Notes: Abstract Hypercalcemia, often associated with certain types of adult tumors, has also been described in pediatric neoplasms. In childhood, the more common associations include lymphoma, leukemia, rhabdomyosarcoma and rarely neuroblastoma. However, recently, several infants with hypercalcemia were described having renal tumors without bone metastases. The following is a case report of a 2-month-old infant who presented with severe hypercalcemia and a large right-sided abdominal mass, which at surgery was diagnosed as a cellular mesoblastic nephroma.

    Notes: Summary Studies of synaptogenesis in the developing organ of Corti in the intact mouse and in culture indicate that the inner and outer hair cells contain three populations of synaptic ribbons, i.e. ribbons adjacent to nerve fibres, free intracellular ribbons and misplaced ribbons apposed to non-neuronal elements. Ribbons adjacent to nerve fibres can be further classified into: ribbons synaptically engaged, ribbons participating in formation of presynaptic complexes only and ribbons that are not engaged to the hair cell membrane. In the developing innervated cultures the ribbon distributions are similar to those in the normal animal. Inner and outer hair cells differ in distribution of the ribbons. In the inner hair cells the ribbons adjacent to the nerve fibres are dominant (over 90%) and most of them (88%) are synaptically engaged. In the outer hair cells the presynaptic ribbons dominate the population (up to 60%) during the first postnatal week when the cells acquire afferent synaptic connections. This stage is followed by a marked reduction in the number of all ribbons. In the intact animal the rapid decrease results in a relative increase of misplaced and free ribbons. These changes are presumably due to the loss of some of the afferents. In the denervated hair cells the distribution of ribbons indicated the presence of conspicuous scatter. In the areas of incomplete denervation, however, the ribbons are apposed to the preserved fibres. Despite denervation, most of the ribbons develop the entire presynaptic complex in apposition to non-neuronal structures. The different populations of synaptic ribbons appear to reflect different stages in synapse formation. Possibly, the synaptic body originates in the interior of the hair cell and subsequently migrates to the cell membrane. In any case, a nerve fibre appears critical in influencing the location of the synaptic ribbon. At the apposition of the ribbon to the hair cell membrane, presynaptic densities are formed and the ribbon appears to become anchored. Typically, the nerve fibre membrane apposed to the presynaptic complex responds with the formation of postsynaptic densities.
