to extract active components from the traditional Chinese medicine Polygonum cuspidatum using a trans-resveratrol imprinted polymer. Good separation and purification of trans-resveratrol and emodin from the Polygonum cuspidatum extract are achieved after condition optimization. The extraction recoveries are 83% and 99% for trans-resveratol and emodin, respectively. The results show that the mol...

Objectives The aim of present randomized controlled clinical trial was to clinically evaluate hard tissue changes after extraction socket preservation procedures compared to natural spontaneous healing. Material and Methods Thirty patients were enrolled in the present study and underwent single-tooth extraction in the premolar/molar areas. Ten sites were grafted with porcine-derived bone cove...

UNLABELLED During healing following tooth extraction, inflammation and the immune response within the extraction socket are related to bone resorption. OBJECTIVE We sought to identify how the alloplastic material used for socket preservation affects the immune responses and osteoclastic activity within extraction sockets. MATERIAL AND METHODS Using a porcine model, we extracted teeth and gr...

Dental luting cements are commonly used in dentistry for cementation of prosthetic restoration. Many previous studies focused on the measurement of the cell viability as the method of cytotoxicity evaluation during biocompatibility study for the material. In this study, the biocompatibility of various dental luting cements were evaluated using the new method of cytokine release measurement in o...

The primary objective of the Atraumatic Restorative Treatment (ART) is to reduce the indication of tooth extraction by means of a low-cost technique. Considering the difficulties of Brazilian public services to meet the demand of care of the low-income population, with lack of care to the adult population, which usually receives only emergency care, the aim of this study is to assess the perfor...

BACKGROUND Propolis is widely used in apitherapy, preparations, and food and beverage additives. Various extraction techniques were applied in the extraction of the biologically active constituents of poplar type propolis in order to compare their efficiency. The methods employed were: traditional maceration extraction, ultrasound extraction (UE), and microwave assisted extraction (MAE). RESU...

A case of a delayed perforation of the right ventricle by the pacemaker lead in a 67-year-old woman is presented. Perforation, mimicking stenocardial symptoms, was incidentally diagnosed on a computed tomography chest scan. Percutaneous lead extraction was successfully performed, with simultaneous implantation of a new pacemaker lead.

Results are presented from 1 year batch experiments where K-rich hyperalkaline pH 13.5 young cement water (YCW) was reacted with sediments to investigate the effect of high pH, mineral alteration, and secondary mineral precipitation on (90)Sr sorption. After reaction with YCW, Sr sorption was found to be greater than 75% in all samples up to 365 days and 98% in a sample reacted for 365 days at ...
