gastric inflammatory myofibroblastic tumor (imt) is a rare tumor with and unpredictable prognosis usually find in young adults. we present an 18-year-old man with gastric imt. he complained of epigastric pain, intermittent fever and night sweating associated with weight loss since two years ago. physical examination showed anemic and cachestic features with mild abdominal tenderness in palpitat...

We propose an adaptive reversible data hiding method with superior visual quality and capacity in which an adaptive generalized difference expansion (AGDE) method is applied to an integer-to-integer subband transform (I2I-ST). I2I-ST performs the reversible subband transform and the AGDE method is a state-of-the-art method of reversible data hiding. The results of experiments we performed objec...

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.                   &nb...

stress-related mucosal damage (srmd) is a significant cause of morbidity and mortality in critically ill patients due to the gastrointestinal blood loss. prophylaxis of srmd with proton pump inhibitors or histamine-2 blockers has gained widespread use in intensive care units. both demonstrated to be effective in reducing clinically significant bleedings, while ppis has shown to exert some anti ...

mucosal surfaces of the body provide a universal entry portal for all known and emerging infectious pathogenic microbes. therefore, it seems that special vaccination strategies are needed for vaccines that can hinder the entry capability of pathogenic microbes through the mucosal surfaces. lactic acid bacteria are widely used in the food industry and are presently applied as delivery vehicles i...

introdouction: cone-beam computed tomography (cbct) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. the aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the cbct technique. materials and methods: in this retrospective study, a total of 105 case...

background and aims. the first few days following the insertion of complete dentures are critical for the patients since they are struggling to adapt to their new dentures. this study aimed to evaluate the most common locations of traumatic ulcerations, their frequency and also the duration and number of adjustment visits required to achieve patient comfort following placement of complete dentu...

background: the airway surfaces are one of the most common ways of entry of infectious agents. oral cavity associated lymphoid tissues are inductive site of humoral immune responses in inflammatory and infectious disorders of the upper respiratory tract. these lymphoid tissues play important roles in the induction of salivary iga. the impact of upper respiratory tract diseases on salivary iga p...

Methods Ten patients were evaluated (6 M:4 F; age 41.7 ± 4.3 y; admission APACHE II score 19.4 ± 1.9; pantoprazole n = 4, and placebo n = 6) from a larger prospective study, in which 209 mechanically ventilated patients were randomised to receive IV pantoprazole (40 mg) or placebo in a double-blind fashion. Patients who received ≥ 5 doses of pantoprazole/placebo (80 patients in total) were elig...
