A number of commensal oral streptococcal species produce a heterogeneous group of proteins that mediate binding of salivary α-amylase. This interaction likely influences streptococcal colonization of the oral cavity. Here, we present draft genome sequences of several strains of oral streptococcal species that bind human salivary amylase.

This paper is a research in the second Language acquisition (SLA) with its focus on the role of input, interaction and output in the development of oral fluency in the EFL context from both a theoretical point of view and a case study. Two instruments were used: tests of oral fluency and face-to-face interviews. The findings showed that non-native oral fluency could be obtained through efficien...

This study involves three dimensions: distance language education (DLE) as the context, videoconferencing as the technology, and the provision of synchronous oral and visual interaction in DLE as the core research problem. This article follows on this author's previous research in regard to the inclusion of oral and visual interaction in distance language learning through the use of Internet-ba...

In this review article, empirical studies published from 2004 through 2014 on second-language (L2) oral proficiency testing are analyzed, with a specific focus on discourse and social interaction in such tests. Taking three common test setups, oral proficiency interviews (OPIs), paired peer tests, and group peer tests as an organizing principle for the studies examined, recent developments in L...

fasting is a religious obligation, which can be challenging for individuals with oral conditions due to its stringent code of conduct. moreover, food abstinence during fasting can restrict oral feeding even further in patients whose nutrition has been already compromised. previous research has mainly concentrated on oral hygiene and gum health, disregarding orodental conditions and diseases. th...

oral malignant melanoma (omm) accounts for 5% of all oral malignancies. it is a rare aggressive neoplasm usually found on the hard palate and gingiva. the etiology is unknown, but tobacco and chronic irritation are suggested as probable causative factors. over 30% of the cases have been reported to arise from pre-existing pigmented lesions. a biopsy is required to establish the diagnosis and th...

Single-point mutations in the gene coding for prothrombin (factor II:A20210) or factor V (factor V:A1691) are associated with an increased risk of venous thromboembolism. The use of oral contraceptives is also a strong and independent risk factor for the disease, and the interaction between factor V:A1691 and oral contraceptives greatly increases the risk. No information is available about the ...

Introduction: Tobacco smoke is involved in the pathogenesis of several diseases in different body systems. Saliva is the first body fluid that confront inhaled cigarette smoke which is injurious to the oral cavity and is associated with several oral diseases and cancer. The aim of our study was to evaluate the influence of smoking on the activity of alpha-amylase in the saliva of healthy smoker...
