squamous cell carcinoma (scc) of the buccal mucosa accounts for 23% to 37% of all intraoral cancers, the prognosis is generally poor. we reported a case of local invasion of buccal squamous cell carcinoma. a 32-year-old man referred to the clinic with a chief complaint of swelling in the right cheek region that initiated from 6 months ago and rapidly grow from one month ago. history of the pati...

Mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. Carbomers are among the best mucosa-adhesive materials known. The aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing Carbomers, either alone or in combination, to the data obtained from assessing the d...

conclusions nucleic acid amplification tests (naats) are very appropriate in detection of infected individuals. detection techniques such as naats are independent of bacterial viability, and have a potential to limit false negative samples, therefore, in our country, the application of different laboratory diagnosis methods including naats with culture as gold standard for determination antimic...

Computational analysis, design and expression of hybrid antibody in Single Chain Fragment Variable (scFv) form for identifying surface antigen factor H binding protein (fHbp) Neisseria meningitidis

objective: sexually transmitted infections (stis) remain a public health problem of major significance in most parts of the world. this study aimed to detect the most prevalent pathogens in patients with signs and symptoms of sti referring to a group of university clinics in tehran. materials and methods: in this cross-sectional study using randomized cluster sampling, 507 consecutive male and ...

Neisseria lactamica is a common and normally harmless commensal of the upper respiratory tract found especially in young children. In the July 2006 edition of this journal, Zavascki and colleagues reported the first case of N. lactamica causing cavitatory lung disease in an adult organ transplant recipient (3). The same year, Wang et al. reported a case of N. lactamica bacteremic pneumonia in a...

Wheat-germ agglutination (WGA) was used to identify 168 strains of Neisseria gonorrhoeae and 105 strains of other Neisseria species in a routine laboratory. About one-third of the meningococci reacted with the lectin and titres with some organisms varied on repeat testing. The technique is regarded as unreliable for the identification of Neisseria species.

Molecular analyses of mip and ompA genes were performed on 20 Neisseria gonorrhoeae isolates. The genes were present with a high degree of conservation in all strains. Sera from patients with urethritis or disseminated gonococcal infections were able to recognize the purified Neisseria gonorrhoeae macrophage infectivity potentiator (Ng-MIP) and Neisseria gonorrhoeae outer membrane protein A (Ng...
