Mono-species bacteria-induced chronic apical periodontitis triggers the aortic inflammatory response via modulation of systemic inflammation and lipid metabolism.

Cardiovascular disease (CVD) is the leading cause of death worldwide and has been confirmed to be associated with a common oral bacterial infection-chronic apical periodontitis (CAP). However, the detailed mechanisms remain controversial. CAP can potentially alter systemic inflammation, lipid metabolism, and gut microbiota, all of which contribute to the progression of the aortic inflammatory response.

Is oxidative stress involved in the hepatic inflammatory response to apical periodontitis? A comparative study in normal and hyperlipidaemic rat.

Aim: The aim of the study was to explore the involvement of oxidative stress (OS) in the hepatic inflammation induced by apical periodontitis (AP). Periapical, systemic and hepatic reaction to AP under hyperlipidaemia was also investigated.

Methodology: A total of 16 male Sprague-Dawley rats were fed with a hyperlipidaemic diet (HD) whereas another 16 rats with a normal diet (ND).

Effects of chronic apical periodontitis on the inflammatory response of the aorta in hyperlipemic rats.

Objectives: To study the effects of chronic apical periodontitis (CAP) on the inflammatory response and initial lesion of aorta in hyperlipemic rats.

Materials And Methods: Sprague-Dawley (SD) rats aged 14 weeks were randomly divided into 4 experimental groups (n = 8), namely, normal diet (ND), high-fat diet (HFD), CAP, and HFD + CAP. The rats were raised under controlled conditions and fed with diet specified for each group.

Minimizing Concentration of Sodium Hypochlorite in Root Canal Irrigation by Combination of Ultrasonic Irrigation with Photodynamic Treatment.

Concentration of sodium hypochlorite (NaOCl) is positively correlated with its effectiveness in root canal disinfection but negatively correlated with its biocompatibility. The objective of this in vitro study was to compare the bactericidal effects among ultrasonic irrigation with different concentration of NaOCl alone or together with photodynamic treatment (PDT) against Enterococcus faecalis (E. faecalis) in infected root canals.

Dual-force ISOMAP: a new relevance feedback method for medical image retrieval.

With great potential for assisting radiological image interpretation and decision making, content-based image retrieval in the medical domain has become a hot topic in recent years. Many methods to enhance the performance of content-based medical image retrieval have been proposed, among which the relevance feedback (RF) scheme is one of the most promising. Given user feedback information, RF algorithms interactively learn a user's preferences to bridge the "semantic gap" between low-level computerized visual features and high-level human semantic perception and thus improve retrieval performance.

Multiview locally linear embedding for effective medical image retrieval.

Content-based medical image retrieval continues to gain attention for its potential to assist radiological image interpretation and decision making. Many approaches have been proposed to improve the performance of medical image retrieval system, among which visual features such as SIFT, LBP, and intensity histogram play a critical role. Typically, these features are concatenated into a long vector to represent medical images, and thus traditional dimension reduction techniques such as locally linear embedding (LLE), principal component analysis (PCA), or laplacian eigenmaps (LE) can be employed to reduce the "curse of dimensionality".

MIAPS: a web-based system for remotely accessing and presenting medical images.

MIAPS (medical image access and presentation system) is a web-based system designed for remotely accessing and presenting DICOM image. MIAPS is accessed with web browser through the Internet. MIAPS provides four features: DICOM image retrieval, maintenance, presentation and output.
