The Roles of Wnt5 and the Drl Receptor in the Development of the Drosophila Olfactory System
… set of projection neuron dendrites, forming glomeruli in stereotypic positions of the antennal lobe. Although many studies have revealed the crucial role of projection neurons in the spatial patterning of glomeruli, the potential instructive role of olfactory neurons was not well investigated …

Investigation of Age Related Differences in the Rewiring of P2-Olfactory Receptor Neurons
… olfactory epithelium, they converge at discrete glomeruli in the olfactory bulb. In the P2 IRES tau-lacZ mouse, the P2 ORN subtype has been previously mapped to two glomeruli, using X-gal staining. To determine if age affects ORN regeneration, left olfactory nerve transections were performed on …

Fluid retention in congestive heart failure-the role of natriuretic peptides and arginine vasopressin
… (IMCD) cells upon stimulation by ANF, and in glomeruli upon stimulation by ANF, BNP and CNP. cAMP accumulation studies were done in IMCD cells upon addition of AVP and forskolin. ANF, BNP and CNP radioligand studies were performed in glomerular membrane. Results showed that baseline …

Ciliary neurotrophic factor (CNTF) im olfaktorischen System von Ratten und Mäusen
… und Mäusen zeigte, dass die Axone CNTF-ir ON in Glomeruli olfactorii projizierten, die bilateralsymmetrisch in beiden BO eines Tieres lokalisiert waren. Diese Symmetrie findet man ebenfalls bei den Projektionen der ON, die das gleiche olfaktorische Rezeptorprotein exprimieren. Die Lokalisation …

The Roles of Age, Glomerular Location, and Collagen Expression in the Canine Kidney: Analysis of a Lifespan Study
… sex, age, and intra-renal location of affected glomeruli to determine the relationship of each in the development of glomerulosclerosis. All dogs examined had some degree of glomerulosclerosis. In the youngest (up to 2 years of age), this was minimal, but was more advanced by middle age (3-7 …

Glomerulosclerosis in the Col1a2-deficient mouse model : homotrimer pathogenesis and MMP expression
… in wildtype, heterozygous and Col1a2-deficient glomeruli to determine whether the pathogenic collagen is homotrimeric in nature, and whether alterations in MMP expression play a role in disease progression. Analysis of whole kidney and isolated glomeruli by immunohistochemistry and CNBr peptide …

Bilateral processing of thermoreception in the olfactory system of larval Xenopus laevis
… Duftstoffe reagierte. Benachbarte olfaktorische Glomeruli reagierten auf olfaktorische und mechanische Reize, ohne eine Reaktion auf emperaturänderungen zu zeigen. Diese lokale und bilaterale Verarbeitung von Temperaturreizen auf der Ebene der olfaktorischen Glomeruli und Mitralzellen zeigt, daß …

Senescent Changes in the Kidney of the Yellow Mud Turtle Kinosternon flavescens
… be lipofuscin or ceroid than did young turtles. Glomeruli in the oldest turtles had significantly fewer glomerular arterioles, and a significant increase in connective tissue in the glomerular tuft. Electron microscope studies indicated that glomeruli became smooth and simplified with advanced …

The Role of Drosophila Odorant Receptors in Odor Coding
… neuronal projections to the antennal lobe glomeruli of adult and larval fly brains. We analyzed expression profiles of 42 ORs, 31 of which are expressed in the adult and 21 in the larva, with an overlap of 10 ORs between the two developmental stages. Our results show surprising complexity …

Processing of plant-associated odors by a subset of projection neurons in the antennal lobe of the female moth, Manduca sexta
… satellite), projected into two small groups of glomeruli. One group was located dorsally and medially in the posterior part of the AL and probably consists of five glomeruli. The other group was situated dorsally and anteriorly and possibly consists of one uniquely identifiable glomerulus. …

Establishing Neuronal Diversity: Regulation of olfactory receptor neuron specification and axon guidance in Drosophila
… receptor and connect to 50 class-specific glomeruli in the antennal lobe of the brain. Here we demonstrate that a cross regulatory network of transcription factors patterns the antennal disc, which contains ORN precursors and will develop into the antenna. These transcription factors create …

Brain-behavioural olfactory asymmetries in Apoidea

Non-Canonical Odor Coding Ensures Robust Mosquito Attraction to Humans
… project their axons to discrete regions, called glomeruli, in the antennal lobe or olfactory bulb, respectively. This organization is believed to be a widespread motif in olfactory systems and has been established dogma since the mid-2000s and is hypothesized to permit the brain to parse which …

Representations and Transformations of Odor Information in the Mouse Olfactory System
… to trace the projections from identified glomeruli in the olfactory bulb to these higher olfactory centers. Electroporation of TMR dextran into single glomeruli has permitted us to define the neural circuits that convey olfactory information from specific glomeruli in the olfactory bulb to …

An Account of Chemical and Mechanical Regulation of TRPC6 Channels in Podocytes

Renal disease in systemic lupus erythematosus: correlation of morphology with clinical course

Electrophysiological and morphological analyses in two species of insects, Protophormia terraenovae and Ceratitis capitata
… insects, the ALs of C. capitata are organized in glomeruli, more tightly packed in the anterior part than the posterior one. Axons of ORNs innervate a bilateral pair of homologous glomeruli and form a commissure between the two ALs, which is a typical feature of Diptera. We counted systematically …
