| cholinergic and gabaergic receptors on fly tangential cells and their role in visual motion detection. | 1. to identify some of the neurotransmitters involved in the processing of visual motion information the pharmacology of transmitter receptors on motion-sensitive visual interneurons (vs and hs cells) was investigated in an in vitro preparation of the blowfly (calliphora erythrocephala) brain. cholinergic and gabaergic drugs were applied in the bath and iontophoretically while recording intracellularly from hs and vs cells. 2. bath-applied carbachol (10 and 100 microm) leads to a depolarization ... | 1996 | 8890292 |
| cutaneous myiasis in three obese cats. | three cats presented with painful, putrid smelling ulcers on their thighs and around their tails. examination of the fly larvae found in the ulcers revealed that the cats suffered cutaneous blowfly myiasis caused by calliphora erythrocephala larvae. obesity was one of the predisposing factors for the development of this parasitic condition. after therapy with ivermectin, the larvae disappeared within two days. | 1996 | 8903143 |
| serotonin-induced intercellular calcium waves in salivary glands of the blowfly calliphora erythrocephala. | 1. blowfly salivary glands have been used extensively as a model system for the analysis of inositol phosphate-dependent signal transduction. to detect and characterize changes in intracellular free calcium ([ca2+]i) that might be expected to be triggered by stimulation with serotonin (5-ht), we have carried out digital calcium-imaging experiments on intact glands using the ca2+-sensitive dye fura-2. 2. 5-ht (1-10 nm) induced repetitive transient increases in [ca2+]i, i.e. ca2+ spikes whose freq ... | 1997 | 9097929 |
| synapse distribution on vch, an inhibitory, motion-sensitive interneuron in the fly visual system. | in this study, the distribution of synapses in the ventral centrifugal horizontal (vch)-a nonspiking, inhibitory, motion-sensitive interneuron in the third visual ganglion (lobula plate) of the blowfly calliphora erythrocephala-was examined by electron microscopy and electrophysiology. the frequency histograms of excitatory and inhibitory postsynaptic potential amplitudes recorded from the vch during contralateral stimulus presentation suggest the existence of three neurons, two excitatory and o ... | 1997 | 9136805 |
| gamma-aminobutyric acid receptor distribution in the mushroom bodies of a fly (calliphora erythrocephala): a functional subdivision of kenyon cells? | antibodies against the drosophila gamma-aminobutyric acid (gaba) receptor subunit rdl were used to investigate the significance of inhibitory inputs to the mushroom bodies in the blowfly (calliphora erythrocephala) brain. the pedunculus and the lobes of the mushroom body, which mainly consist of kenyon cell fibers, revealed strong immunoreactivity against rdl. pedunculi, alpha- and beta-lobe show characteristic unstained core structures with concentric labeling along the neuropile axis. the gamm ... | 1997 | 9184984 |
| biogenesis of surface domains in fly photoreceptor cells: fine-structural analysis of the plasma membrane and immunolocalization of na+, k+ atpase and alpha-spectrin during cell differentiation. | electron microscopic examination of pupal and adult blowfly (calliphora erythrocephala) retina provides novel details on the biogenesis of the photoreceptor surface, particularly regarding the development of the microvillar rhabdomere and associated structures, such as the submicrovillar endoplasmic reticulum. localization of the na+, k(+)-atpase on the surface of developing photoreceptors has also been examined by immunofluorescence confocal microscopy and immunogold electron microscopy. na+, k ... | 1997 | 9184991 |
| developmental regulation of yolk protein gene expression in anastrepha suspensa. | a partial cdna clone for the 48,000 dalton yolk polypeptide gene from anastrepha suspensa was isolated from a cdna expression library using a yolk polypeptide antibody probe and hybridization to the drosophila melanogaster yolk protein 1 gene. the sequenced dna has greatest homology to the yolk protein genes from ceratitis capitata, d. melanogaster, and calliphora erythrocephala and, similar to these genes, shares amino acid sequence domains with those from lipases. rna hybridization studies ind ... | 1997 | 9243791 |
| characterisation of large second-order ocellar neurones of the blowfly calliphora erythrocephala | 1. blowflies have twelve large, second-order ocellar neurones (l-neurones) with axons in the single ocellar nerve. these neurones have fairly restricted arborizations in the posterior slope neuropile of the protocerebrum and cell bodies in the nerve, near to the fused ocellar retinae. 2. like ocellar l-neurones of other insects, or large second-order neurones of the fly compound eye, blowfly l-neurones hyperpolarise in response to increases in light intensity and depolarise in response to decrea ... | 1994 | 9317701 |
| dendritic structure and receptive-field organization of optic flow processing interneurons in the fly. | the third visual neuropil (lobula plate) of the blowfly calliphora erythrocephala is a center for processing motion information. it contains, among others, 10 individually identifiable "vertical system" (vs) neurons responding to visual wide-field motions of arbitrary patterns. we demonstrate that each vs neuron is tuned to sense a particular aspect of optic flow that is generated during self-motion. thus the vs neurons in the fly supply visual information for the control of head orientation, bo ... | 1998 | 9535957 |
| calcium store depletion activates two distinct calcium entry pathways in secretory cells of the blowfly salivary gland. | ca2+ influx into secretory cells of the intact salivary gland of the blowfly calliphora erythrocephala elicited by the agonist 5-hydroxytryptamine (5-ht) or the ca2+ uptake inhibitor thapsigargin was studied by using fura-2 and digital fluorescence imaging and by recordings of the transepithelial potential. application of saturating [5-ht] in the absence of ca2+ (ca2+o) from the bathing saline did not affect the initial ca2+ transient but greatly attenuated the subsequent sustained ca2+ elevatio ... | 1998 | 9570010 |
| the mechanism mediating regenerative intercellular ca2+ waves in the blowfly salivary gland. | intercellular ca2+ signaling in intact salivary glands of the blowfly calliphora erythrocephala was studied by fluorimetric digital imaging combined with microinjection of putative messenger molecules. iontophoretic injection of d-myo-inositol 1,4, 5-trisphosphate (insp3) into salivary gland cells evoked regenerative intercellular ca2+ waves that spread through the impaled cell and several rows of surrounding cells. ca2+ increases induced by microinjection of ca2+ ions were confined to the injec ... | 1999 | 10369663 |
| temperature-dependence of neuronal performance in the motion pathway of the blowfly calliphora erythrocephala | raising the head temperature within a behaviourally relevant range has strong effects on the performance of an identified neuron, the h1 neuron, in the visual motion pathway of blowflies. the effect is seen as an increase in the mean amplitude of the responses to motion under both transient and steady-state conditions, a considerable decrease in the response latency and an improvement in the reliability of the responses to motion. these temperature-dependent effects are independent of whether th ... | 1999 | 10539965 |
| evolution of 5s rrna gene families in drosophila. | in drosophila virilis, the three clusters of 5s rrna genes on chromosome 5 comprise two different gene families (b and c), which differ profoundly in the organization of their spacer sequences. while c-type genes, which are found in two of the clusters, exhibit a true repetitive character, the b-type genes of the third cluster are each embedded in completely different genomic environments. southern blots of genomic dna of different d. virilis subspecies, d. hydei and d. melanogaster probed with ... | 2001 | 11448042 |
| d-tubocurarine chloride: effect on insects. | injection of d-tubocurarine chloride into certain insects produces complete flaccid paralysis. the site of injection is closely related to the region of primary paralysis. the effect depends on concentration, with distinct differences in the optimum concentrations for various species so far tested. a dose-response curve has been prepared for calliphora erythrocephala. | 1966 | 12325354 |
| a candidate olfactory receptor subtype highly conserved across different insect orders. | candidate olfactory receptors of the moth heliothis virescens were found to be extremely diverse from receptors of the fruitfly drosophila melanogaster and the mosquito anopheles gambiae, but there is one exception. the moth receptor type hr2 shares a rather high degree of sequence identity with one olfactory receptor type both from drosophila (dor83b) and from anopheles (agamgpror7); moreover, in contrast to all other receptors, this unique receptor type is expressed in numerous antennal neuron ... | 2003 | 12827420 |
