A biracial sample of 348 elementary school children who were in the first grade were assessed for open-mouth posture (OMP) in the natural environment. In addition, rhinometry was performed on 296 of the children. Means were computed for percent OMP and cross-sectional nasal airway. Results indicated that, in general, these children exhibited relatively high rates of OMP. Boys displayed signific...

The use of liposome as an adjuvant and a vaccine carrier has been cited previously in the literature. It has also been shown to be effective in enhancing the immunogenicity of vaccine candidates. BALB/c mice immunized subcutaneously with outer membrane protein (OMP) of Brucella abortus S19 vaccine strain entrapped in a commercial cationic liposome (S19-OMP-liposome) for vaccine delivery, showed...

In this issue of the Canadian Journal of Ophthalmology, Astle et al. identify the need for more well-trained ophthalmic medical personnel (OMP) and provide strategies for the long-term success of OMP training. They analyzed data collected from Canadian ophthalmologists and OMP regarding the value and role of certified eye care personnel. Even though the environment is changing and much is out o...

The one-minute preceptor (OMP) was originally developed in the ambulatory care setting as a time-efficient teaching technique for learner-centered clinical training. There are also possible advantages of using the OMP in the gross anatomy laboratory. However, in a previous study it was found that providing training to experienced gross anatomy teachers in the use of the OMP did not result in im...

Orthogonal matching pursuit (OMP) is a widely used compressive sensing (CS) algorithm for recovering sparse signals in noisy linear regression models. The performance of OMP depends on its stopping criteria (SC). SC for OMP discussed in literature typically assumes knowledge of either the sparsity of the signal to be estimated k0 or noise variance σ , both of which are unavailable in many pract...

Ehrlichia ewingii, a tick-transmitted rickettsia previously known only as a canine pathogen, was recently recognized as a human pathogen. E. ewingii has yet to be cultivated, and there is no serologic test available to diagnose E. ewingii infection. Previously, a fragment (505 bp) of a single E. ewingii gene homologous to 1 of 22 genes encoding Ehrlichia chaffeensis immunodominant major outer m...

Complex U is composed of orotate phosphoribosyltransferase (EC 2.4.2.10) and orotidine-5’-phosphate decarboxylase (EC 4.1.1.23), the last two enzymes of the de nouo pathway for pyrimidine biosynthesis. Since the two enzymes have proved inseparable so far, the equilibrium constant for the phosphoribosyltransferase activity has been determined under conditions where the decarboxylase activity was...

Olfactory mucosa was excised from the heads of embryonic day 15 (E15) rat fetuses, prior to the appearance of olfactory marker protein (OMP), and cultured with or without the presumptive olfactory bulb. Specific immunohistochemical staining for the OMP was detected in both groups of explants 6 days after explantation. At no time do the supporting cells and basal cells show positive OMP staining...

Olfactory marker protein (OMP) is highly and selectively expressed in primary olfactory sensory neurons (OSNs) across species, but its physiological function remains unclear. Previous studies in the olfactory epithelium suggest that it accelerates the neural response to odorants and may modulate the odorant-selectivity of OSNs. Here we used a line of gene-targeted mice that express the fluoresc...

The outer membrane protein (OMP) preparation of Salmonella typhi was observed to have several immunomodulatory properties. Treatment of mice with an intraperitoneal injection of the OMP preparation enhanced both cellular and humoral responses of the mice to an unrelated antigen, a killed vaccine of Mycobacterium vaccae; both the delayed-type hypersensitivity (DTH) response and the antibody tite...
