Characterization of Staphylococcus Aureus of Bovine Origin
… The strains isolated from the mammary gland and nasal cavity, although mostly of bovine biotype, differed in their lytic spectra. It is speculated that these differences are due to basic differences between these two ecological niches (mammary gland and nasal cavity).

Development of a novel in vitro system for nasal drug delivery development
There is currently, no ideal system for studying nasal drug delivery in vitro. The existing techniques such as the Ussing chamber and cell culture all have major disadvantages. Most importantly, none of the existing techniques accurately represent the interior of the nasal cavity, with its airflow …

Structure, function and context : the impact of morphometry and ecology on olfactory sensitivity
… degrees among different mammalian orders. Nasal cavity specimens were measured using radiologic (CT scan) and histologic (light microscopy) techniques. Surface areas and volumes of the nasal cavity were used to calculate the Olfactory Uptake Efficiency (OUE). OUE is significantly related to …

Investigation of intercellular transport and biodistribution of curcumin across the nasal epithelium in hamsters
… compounds to the brain after instillation in the nasal cavity. The exact mechanism(s) by which compound translocation from the nose to the brain occurs are unknown. Several hypothesized pathways for compound transport have been proposed and include movement through various nerves in the nasal …

“If it’s in the game, it’s in the game” : Sondra Perry and technological likeness
… Projection and Five Universal Shot Trainers with Nasal Cavity, Pelvis, Orbit, and Axes, which bridges virtual and physical worlds to tell the story of a videogame avatar modeled off her twin brother. She contextualizes this narrative within the circulation of imagery of Black people in canonical …

Autoradiographische Untersuchungen zur Toxikokinetik von Myosmin in Ratten
… responsible for tumours in oesophagus, oral and nasal cavities. Whereas the pharmacokinetics and metabolism of NNN have been studied in detail no such data have been available for myosmine. In the present study time-dependent distribution, binding and excretion of radiolabelled myosmine was …

THE RESPIRATORY RESPONSE OF TRPV1 KNOCKOUT MICE TO TRIGEMINAL IRRITANTS
… of polymodal neurons which innervate the nasal cavity, nasopharynx, oral cavity and cornea. Trigeminal nociceptive fibers are stimulated by a wide variety of chemical irritants. However, the mechanism of stimulation is known for only a few compounds. TRPV1 channels, for example, are …

The Relationship of Oral Anatomy and Trumpet Performance: Prediction of Physical Talent
… crowding of the teeth; volume of the oral and nasal cavity, sinuses, and pharynxes; thickness and width of the lips, distances across the face; and others. In phase 3, extensive statistical analyses were conducted to examine relationships among questionnaire, skills test, and oral anatomy …

Skeletal Changes after Rapid Maxillary Expansion and Fixed Orthodontic Treatment: A CBCT Study
… buccal maxillary widths, palatal alveolar angle, nasal width, nasal floor width, and maxillary sinus width at C1, P1, P2, and M1 were compared by using Wilcoxon signed rank, Kruskal-Wallis, and Wilcoxon rank sum tests. Pearson correlation analyses were also performed (α = 0.05). <strong>Results: …

Nasal Septal Deviation and Nasofacial Skeletal Form: A Cross-Sectional CBCT Study of a 7-18 Year-Old Cohort
… study was to examine the relationship between nasal septal deviation and the shape of the nasofacial skeleton during ontogeny. Materials and Methods: Nasal septal size was retrospectively measured on existing cone-beam computed tomograms (CBCT) in 66 mixed-sex orthodontic patients of European …

Rhinomanometry in clinical use. A tool in the septoplasty decision making process.
Subjective nasal obstruction is a common chronic complaint caused by mucosal disease, skeletal abnormality or a combination of both. The challenge is to determine the main cause and to decide whether the intervention should be medical or surgical. Diagnosis is done by a combination of rhinoscopy, …

Patterns in the Presence of Respiratory Tract Mycoplasmas in Four Species of North American Tortoises
… chain reactions (qPCR) on DNA extractions from nasal flushes. The qPCR process showed that both Mycoplasma pathogens were present in the four species of tortoises. Statistical analyses indicated that "species" and "sample site" were significantly associated with the presence of M. agassizii, …

Axon Development and Synapse Formation in Olfactory Sensory Neurons
… based on post-natal electroporation of the mouse nasal cavity. This technique allowed me to perform a temporal study where I followed the elaboration of axons and synapses in olfactory sensory neurons at different post-natal ages. The results show that olfactory sensory axons develop with …

Hypernasal Speech Analysis via Emperical Mode Decomposition and the Teager-Kasiser Energy Operator
… to develop a clear method for detecting hypernasality in speech. For speech pathologists, hypernsality is a critical diagnostic used for judging the severity of velopharyngeal (nasal cavity/mouth separation) inadequacy in children with a cleft lip or cleft palate condition. For physicians and …

Accelerating development of treatments for trigeminal neuralgia using intranasal delivery and a novel behavioral screening device for rats.
… orofacial and brain structures involved. Intranasal administration targets these structures while minimizing systemic exposure and side effects. Lidocaine was intranasally administered to rats, and the trigeminal nerve and trigeminally-innervated structures (teeth, temporomandibular joint …

Delivery of a Small Hydrophobic and Large Hydrophilic Molecule via Intranasal Route
The intranasal route of drug administration is widely known to be a non-invasive route that has the potential to carry a drug directly to the central nervous system (CNS). Drugs with low solubility and large molecular weight are two common problems encountered which interfere with the delivery of …

Development of implantable devices for schizophrenia treatment
… side effects. To overcome this problem, intranasal administration can be an alternative not only to improve brain-targeting drug efficacy, but also to reduce drug dosage and minimise systemic side effects since the human nasal cavity provides direct transport from the nose to the brain. …

Gnotobiotic Pig Models for the Study of Enteric Pathogen Replication and Pathogenesis
… HRV can replicate in the salivary glands and nasal cavity of Gn pigs in addition to the small intestine. HRV infection primed immune responses in the ileum, tonsils, and facial lymph nodes; infection also induced high levels of systemic and mucosal rotavirus specific antibody responses. Moving …
