Progenitor/stem cell populations of epithelium are known to reside in the small-sized cell population. Our objective was to physically isolate and characterize an oral keratinocyte-enriched population of small-sized progenitor/stem cells. Primary human oral mucosal keratinocytes cultured in a chemically defined serum-free culture system, devoid of animal-derived feeder cells, were sorted by rel...

conclusions shiitake essential oil is an effective anti-bacterial and anti-biofilm agent on important oral pathogens and has a possible therapeutic potential as an oral anti-biofilm agent. results no inhibitory effect was observed on f. nucleatum biofilms (p > 0.05). significant disruptive properties on a. actinomycetemcomitans at values lower than the mic (3.90 µg/ml) was detected (p < 0.05). ...

total of 270 quail fertile eggs were set in hatchery. experimental groups including: negative control (neither received probiotic treatment nor challenged by salmonella), positive control (challenged by salmonella but not probiotic treatment) and 7 in hatchery administration methods: in ovo injection, spray, oral gavage, cloacal drinking (cloacal inoculation), cloacal drinking – in ovo injectio...

Background: This study was undertaken to establish the characterization of cultured oral mucosal epithelium and introducing them as an alternative source for reconstruction of ocular surface disease. Methods: Human oral epithelial cells were cultured on simple media (DMEM/HF12) as control and co-cultured on mitomycin C-treated 3T3 feeder layer, on the amniotic membrane (AM) without nitrocellulo...

We investigated the efficacy of oral and parenteral Mycobacterium bovis bacille Calmette-Guerin Danish strain 1331 (BCG) in its ability to protect white-tailed deer (Odocoileus virginianus) against disease caused by M. bovis infection. Twenty-two white-tailed deer were divided into four groups. One group (n=5) received 10(9) colony-forming units (cfu) BCG via a lipid-formulated oral bait; one g...

INTRODUCTION Oral-derived bacteremia may occur after several dental procedures and routine daily activities. Some conditions of the oral cavity may favor episodes of bacteremia. This would be the case of patients with diabetes mellitus and periodontitis, who exhibit exacerbated gingival inflammation and may be more prone to developing oral-derived bacteremia.  OBJECTIVE To compare the effecti...

The six Veillonella species found in the human oral cavity are among the most abundant members of the oral flora, occurring in both supra- and subgingival dental plaque as well as on the oral mucosa. Epidemiological data have also implicated these species in the development of the most common oral diseases. Despite their ubiquity, abundance, and ecological significance, surprisingly little is k...

background and aim: oral mucosal lesions have various prevalence rates among different populations. few studies have evaluated the frequency of oral mucosal lesions in iranian population. this study aimed to determine the frequency of oral mucosal lesions and the related factors.                        materials and methods: this descriptive study was conducted based on the data in the archives...
