The hantaviral load in tissues of naturally infected rodents.
Hantaviruses cause a lifelong and asymptomatic infection in naturally infected hosts as well as in experimentally infected rodents. Understanding the ecology and pathogenesis of hantaviruses requires an interdisciplinary research approach, which links laboratory experiments with results gained from...
Efficacy of alternative dosing regimens of poly-aggregated amphotericin B
A new poly-aggregated form of amphotericin B was formulated as a non-microencapsulated form (P-AMB) or incorporated in albumin microspheres (MP-AMB) and compared with the conventional amphotericin B formulation (D-AMB). Mice were infected with Candida albicans and treated with two different intermit...
Minicollagen-15, a Novel Minicollagen Isolated from Hydra, Forms Tubule Structures in Nematocysts
We report the cloning and characterization of a novel minicollagen in Hydra, designated minicollagen-15 (NCol-15). NCol-15, like NCol-3 and NCol-4, shows deviations from the canonical cysteine pattern in its terminal cysteine-rich domains (CRDs). Minicollagens share common domain architectures with...
Biphasic and dually coordinated expression of the genes encoding major shell matrix proteins in the pearl oyster Pinctada fucata.
Regional expression patterns of shell matrix protein genes of Pinctada fucata were investigated using real-time quantitative polymerase chain reaction (PCR) and in situ hybridization. Six shell matrix proteins examined in this study indicated a distinct biphasic pattern of expression, falling into o...
Olfactory adaptation depends on the Trp Ca2+ channel in Drosophila.
These results indicate that olfactory response and adaptation can be distinguished. Trp expression was detected in the developing antenna but, surprisingly, not in the mature antenna. These results, together with temperature-shift analysis of a temperature-sensitive trp mutant, provide evidence of a...
The preimaginal stages and development of Spalangia cameroni Perkins (Hymenoptera: Pteromalidae) on Ceratitis capitata (Wiedemann) (Diptera:...
Our results show that the eggs and different instars of S. cameroni can be unambiguously identified only by SEM. Therefore, characterization of the immature stages of Spalangia species using SEM should be done before subsequent routine identifications using a binocular microscope or stereomicroscope...
Micromechanical properties of consecutive layers in specialized insect cuticle: the gula of Pachnoda marginata (Coleoptera, Scarabaeidae) an...
We studied the different cuticular layers of the head part (gula) of the head-to-neck ball articulation of Pachnoda marginata and of the photomechanic infrared (IR) sensilla of Melanophila acuminata on the basis of cross sections. In our study, we combined histological methods (i.e. detection of the...
Twisting and bending of biological beams: distribution of biological beams in a stiffness mechanospace.
Most biological beams bend and twist relatively easily compared to human-made structures. This paper investigates flexibility in 57 diverse biological beams in an effort to identify common patterns in the relationship between flexural stiffness and torsional stiffness. The patterns are investigated...
Ultrastructural investigation of the vesicular glands in Scutigera coleoptrata (Chilopoda, Notostigmophora).
In the notostigmophoran centipedes, two pairs of vesicular glands have evolved. These paired glands are situated in the first and second trunk segment and open via cuticular ducts in the upper part of the particular pleura. The vesicular glands of Scutigera coleoptrata were investigated using light...
Morphological and isoenzymatic differentiation of Phlebotomus perniciosus and Phlebotomus longicuspis (Diptera: Psychodidae) in Southern Mor...
Morphological and enzymatic characterization of Phlebotomus perniciosus and Phlebotomus longicuspis in Morocco is reported. Twenty-nine localities in central and southern of Morocco were sampled and compared with three localities from the Rif (northern Morocco). For morphological study, sand flies w...
