    Sulfur Dioxide Inhibition of Anthocyanin Degradation by Phenolasea (1965)

    Notes: The degradation of cyanidin 3-gentiobioside by mushroom phenolase in a model system containing catechol is inhibited by SO2. In a citrate phosphate buffer, pH 6.5, with 2.8 × 10−5M catechol and 3.3 mg commercial enzyme per 100 ml reaction mixture, 8 ppm of SO2 completely checked the anthocyanin degradation. In tart cherry juice, under similar conditions but with no catechol added, 30 ppm SO2 were required for a practically complete inhibition. At lower pH the inhibition is accomplished by smaller SO2 concentrations.

    Vertebral dysplasia in young fish exposed to the herbicide trifluralin (1979)

    Notes: Abstract. Sheepshead minnows, Cyprinodon variegatus Lacépède, exposed to 5.5 to 31 μg/1 of the herbicide trifluralin, throughout their first 28 days of life, developed a heretofore undescribed vertebral dysplasia. This dysplasia consisted of semi-symmetrical hypertrophy of vertebrae (three to 20 times normal), characterized by foci of osteoblast and fibroblasts actively laying down bone and bone precursors. Effects of the abnormal vertebral development were dorsal vertebral growth into the neural canal, ventral compression of renal ducts, and longitudinal fusion of vertebrae. Pish, exposed for 51 days to 16.6 μg/1 trifluralin and thereafter depurated for 41 days, showed no increase in vertebral dysplasia during depuration; however, residual spinal column damage was evident. Serum calcium concentrations were elevated in adult fish exposed for 4 days to 16.6 μg/1 trifluralin. Fluorosis or mimicry of hypervitaminosis A are considered possible mechanisms for the osseous effect, but are not considered to be the only possible causes. The highly predictable nature of this disorder in experimental exposures strengthens the probability that young fish may serve as experimental models for determining effects of chemicals on early vertebrate ontogeny, particularly in regard to skeletal development.

    Information processing along the course of a visual interneuron (1977)

    Notes: Summary Locust ocellar retinal cells are innervated by giant second order cells, 2 mm long, which show discrete zones of integration along their course, including a major zone in the axonal length of the neuron. The complex synaptic arrangements which exist between higher-order afferent and efferent cells and these second order cells along their course suggests that transmission takes place by the electrotonic spread of slow potentials. The size and accessibility of these visual interneurons offers a unique preparation for examining mechanisms of graded synaptic transmission.

La saveur amère peut être attribuée à l'élimination du proton imidique de la saccharine.

    Multimodal approach to diagnosis of hamartoma of the spleen (1977)
    Springer
    Pediatric radiology 5 (1977), S. 239-241

    Notes: Abstract Splenic hamartoma is a benign, primary neoplasm which usually causes a mass in the left upper quadrant of the abdomen. If radionuclide studies show a space-occupying lesion in the spleen that appears solid on the ultrasonogram, and selective abdominal arteriography reveals a richly vascular splenic tumor, hamartoma of the spleen should be the preoperative diagnosis.

    The pre-Achilles fat pad: An aid to early diagnosis of local or systemic disease (1977)

    Notes: Abstract The normal pre-Achilles fat pad seen on the lateral radiograph of the ankle is a triangular lucency with sharp, gently curving borders. Changes in the sharpness or contour of the fat pad margins may be associated with local or systemic disease. Alteration of the fat pad often precedes recognizable bone or joint abnormalities. Careful scrutiny of the pre-Achilles fat pad on the lateral ankle radiograph should help in early detection of ankle or systemic disease.

    The projection of ocellar neurons within the brain of the Locust, Schistocerca gregaria (1975)

    Notes: Summary Cobalt iontophoresis of the median and lateral ocellar nerves of Schistocerca gregaria, combined with silver impregnated sections of the brain, has demonstrated the projection areas of the large and medium-sized ocellar afferent neurons. These neurons terminate within the brain and their cell bodies lie within the protocerebrum. Ocellar neurons project to two discrete areas on each side of the brain, each area receiving input from a different set of fibres. Both postero-dorsal complexes receive an input from two large ipsilateral and two large median fibres. Their dendritic fields maintain an ordered spatial array relative to one another. The two antero-lateral complexes receive an input from one large ipsilateral fibre and medium-sized ipsilateral and median small-field afferent fibres. Each lateral ocellus has two large fibres in common with the median ocellus. These lateromedial fibres receive photoreceptor input from both ocelli but form no major arborisations within the brain. The lateral ocellar tracts appear to form a third ocellar association area since higher-order neurons branch amongst the lateral and latero-medial fibres within the tract. The axons of the higher-order neurons descend to the ventral cord via the circum-oesophageal commissures.
