    Notes: Summary A new aryl hydrazone structure with high insecticidal activity against the Australian sheep blowfly,Lucilia cuprina, was shown to have a higher activity as an uncoupler of oxidative phosphorylation in insect compared to mammalian mitochondrial preparations. This compound possesses the requirements of other uncouplers in its measured pKa and lipid solubility. However, when compared to a closely related structure with similar physicochemical properties, its insecticidal and insect mitochondrial uncoupling activities are greater and it exhibits decreased mammalian toxicity corresponding to this differential biochemical selectivity.

    Notes: Summary This study demonstrates polymorphisms in both the length and in the restriction enzyme cleavage sites of honeybee mitochondrial DNA (mtDNA). The levels of variation are typical of those found in other metazoan species. These polymorphisms are potentially useful for the identification of Africanized bees in the western hemisphere and for study of honeybee phylogenetics.

    Notes: Abstract Concentrations of 40 elements were determined in tissues and whole bodies of mussels (Bathymodiolus thermophilus) and/or whole bodies of limpets (Neomphalus fretterae) collected from the submarine thermal springs on the Galápagos Rift in 1977. Concentrations of Ag, As, Fe, Mn, Mo, Se, Sr, and Zn were comparable or elevated relative to those of intertidal mollusks, which have been utilized as indicators of anthropogenic trace-metal contamination. Both species contained concentrations of some elements (e.g. Ag, As, Fe, Mn, Mo, Se, Zn) which corresponded with the elevated levels of those elements discharged from hydrothermal vents. Many elements were most enriched in the gills and digestive glands of the mussels. Iron:manganese ratios of those tissues were similar to ratios of pelagic and transitional sediments, indicating that metal-rich suspended particulates had been absorbed onto mucous membranes. Comparisons with other benthopelagic organisms were precluded, since the present data represent essentially the only trace-element analyses of deep-sea macroinvertebrates.

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary L-644,122 is a chemically stable vasodilator prostaglandin analogue. It is a selective renal vasodilator in dogs. The object of the present study was to determine whether it increases effective renal plasma flow (ERPF) in man. L-644,122 was administered intravenously to 4 healthy volunteers and by mouth to 4 mild hypertensives. It did not increase ERPF. Instead it acted as a non-specific vasodilator, lowering diastolic blood pressure and increasing heart rate. An unexpected increase in glomerular filtration rate (19% greater than placebo) after low dose intravenous L-644,122 merits further study.

    Description / Table of Contents: Zusammenfassung Anatomie, radiographische Darstellung und pathologische Bedeutung der tentoriellen Arterie, die ein Ast der kavernösen Verlaufsstrecke der A. carotis interna ist, werden besprochen. Es werden 18 Patienten mit verbreiterter tentorieller Arterie beschrieben. Es handelte sich dabei mit fast gleicher Häufigkeit um Tentorium-Meningeome (4), maligne Gliome (6) und arteriovenöse Mißbildungen (4). Zusätzlich fand sich ein einzelner Fall, in dem dieses Gefäß ein Akustikusneurinom versorgte; eine solche Beziehung ist bisher noch nicht beschrieben worden. In drei Fällen stand die erweiterte Arterie in keinem erkennbaren Zusammenhang zu der bestehenden Erkrankung.
    Abstract: Résumé Les auteurs ont étudié l'anatomie, la visualisation radiographique et la signification pathologique de l'artère de la tente, branche de la portion caverneuse de la carotide interne. Dix huit patients ont présenté une artère tentorielle élargie: 4 cas de méningiome de la tente, 6 cas de glioblastome, 4 cas d'angiome, 1 cas de neurinome du VIII, vascularisé par l'artère tentorielle (ceci n'a pas été décrit auparavant). Dans les trois derniers cas, l'élargissement de l'artère tentorielle n'était pas formellement en rapport avec la lésion présente.
    Notes: Summary The anatomy, radiographic visualization and pathological significance of the tentorial artery, which is a branch of the cavernous portion of the internal carotid artery, is discussed. Eighteen patients with an enlarged tentorial artery are described. The diagnoses in these patients were almost equally divided among tentorial meningiomas (4), malignant gliomas (6) and arteriovenous malformations (4). In addition there was a single case in which this vessel fed an acoustic neuroma; this relationship has not been previously reported. In three cases the enlarged artery was not recognizably related to the lesion present.

    Notes: We present a systematic study of the effect of size and shape on the spectral response of individual silver nanoparticles. An experimental method has been developed that begins with the detection and characterization of isolated nanoparticles in the optical far field. The plasmon resonance optical spectrum of many individual nanoparticles are then correlated to their size and shape using high-resolution transmission electron microscopy. We find that specific geometrical shapes give distinct spectral responses. In addition, inducing subtle changes in the particles' morphology by heating causes a shift in the individual particle spectrum and provides a simple means of tuning the spectral response to a desired optical wavelength. Improved colloidal preparation methods could potentially lead to homogeneous populations of identical particle shapes and colors. These multicolor colloids could be used as biological labels, surface enhanced Raman scattering substrates, or near field optical microscopy sources covering the full range of wavelengths in the visible spectrum. © 2002 American Institute of Physics.
