The radiograph on this issue’s front cover demonstrates a normal image of the abdomen. It is a favourite of mine and one that I use routinely in teaching undergraduate medical students. Take a good look. You may notice a curvilinear gas density projected within the pelvis. See it? This is what a tampon looks like (figure 1). It’s a subtle finding, but once seen, the radiographic configuration i...

Abstract Predicting the penetration depth during electron beam welding (EBW) is important, but accuracy of current predictive models highly varied, depending on type and number data used. This paper develops compares several prediction for EBW uniquely influence used, as well measurement modelling methods. Although accelerating voltage, speed are essential inputs, additional focal position shap...

Deletions in open addressing tables have often been seen as problematic. The usual solution is to use a special mark ’deleted’ so that probe sequences continue past deleted slots, as if there was an element still sitting there. Such a solution, notwithstanding is wide applicability, may involve serious performance degradation. In the first part of this paper we review a practical implementation...

Background Cytokines are significant in the development and progression of chronic periodontitis (ChP) and type 2 diabetes mellitus (DT2). Insufficient information is available regarding the pro- versus anti-inflammatory cytokines in ChP's influence on systemic levels of cytokines on DT2. This study investigated the levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-4 and IL-6 in the s...

Objective: The purpose of this review was to examine how tissue architecture, surgical procedures, implant components and prosthetic factors contribute collectively toesthetic success in the maxillary anterior and premolar region (esthetic zone).Materials and methods: Pubmed, Embase and the Cochrane electronic databases weresearched for prospective human studies that investigate sin...

Diabetes has reached epidemic levels in North America and continues to rise in prevalence, generating a significant financial burden on society. The strong link between type 2 diabetes and periodontitis provides a sound basis for dental professionals to screen for and help manage diabetic patients. Literature from journals of both medicine and dentistry was included to provide a comprehensive e...
