The aim of the present study was to investigate whether the vibratory characteristics of obturator prostheses are affected by bulb design, i.e.: the hollow or buccal flange type, and different lateral and medial bulb heights. Buccal flange and hollow bulb obturator prostheses were fabricated with two different lateral bulb wall heights and two different medial bulb wall heights. Ultimately, eig...

In this study 269 phosphate solubilizing bacteria (PSB) strains were isolated from onions rhizosphere. The 15 most efficient PSB selected. Based on BIOLOG profiling and the LOPAT test system, identified as Enterobacter cloacae (7), Yersinia intermedia, Pantoea agglomerans, Bacillus subtilis(2), pumilius, Lysinibacillus sphaericus atrophaeus(2). effect onion growth was investigated under greenhou...

Early olfactory axons follow a specific pathway to reach the developing telencephalon. We observed that a subpopulation of these axons, the pioneer olfactory axons, penetrate into the ventricular zone of a highly restricted region of the telencephalon at E13 and E14. At E15, this same telencephalic region evaginates to form the olfactory bulb. To investigate the possibility that the pioneer olf...

OBJECTIVE To determine whether sacrifice of the internal jugular vein (IJV) causes subsequent changes in the jugular bulb. STUDY DESIGN Retrospective chart review. SETTING Tertiary referral center. PATIENTS Patients were selected by CPT code for neck dissection and were included in the study if they had undergone unilateral neck dissection and had preoperative and postoperative computed t...

The main olfactory bulb is a critical relay step between the olfactory epithelium and the olfactory cortex. A marked feature of the bulb is its massive innervation by cholinergic inputs from the basal forebrain. In this study, we addressed the functional interaction between cholinergic inputs and intrinsic bulbar circuitry. Determining the roles of acetylcholine (ACh) requires the characterizat...

The olfactory bulb receives rich glutamatergic projections from the piriform cortex. However, the dynamics and importance of these feedback signals remain unknown. Here, we use multiphoton calcium imaging to monitor cortical feedback in the olfactory bulb of awake mice and further probe its impact on the bulb output. Responses of feedback boutons were sparse, odor specific, and often outlasted ...

Perturbations in neural circuits can provide mechanistic understanding of the neural correlates of behavior. In M71 transgenic mice with a "monoclonal nose", glomerular input patterns in the olfactory bulb are massively perturbed and olfactory behaviors are altered. To gain insights into how olfactory circuits can process such degraded inputs we characterized odor-evoked responses of olfactory ...
