OBJECTIVES The purpose of this study was to assess the in vitro antibacterial activity of four formulations of calcium hydroxide [Ca(OH)(2)] pastes against Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa and Streptococcus mutans. METHODS A broth dilution test was performed, and the lengths of time for different pastes to kill the microbial cells were recorded and statisti...

A chiral molecular gelation system, as a host, was used to effectively realize enantioselectivity using the simple carboxylic acid functional group. For this purpose, an L-glutamic-acid-based lipidic amphiphile (G-CA) with head group selected and its responsiveness cationic guest molecules investigated. The dispersion morphology of G-CA in solution state examined by confocal transmission electr...

PURPOSE The aim of this study was to evaluate, in vitro, the quality of calcium hydroxide [Ca(OH)(2)] paste filling (Ultracal, Ultradent) associated or not with Ca(OH)(2)-containing gutta-percha points (Calcium Hydroxide Plus Points, Roeko) in curved root canals. MATERIAL AND METHODS One hundred and twenty roots of extracted human teeth, randomly divided into three curvature ranges (mild - 0 ...

AIM The aim of the study was to evaluate the usefulness of CA125 measurements in ovarian cancer diagnostics in pre- versus postmenopausal women. MATERIAL AND METHODS The study group consisted of 99 serum specimens of women diagnosed with ovarian cancer (28 pre- and 71 postmenopausal). The control group consisted of 86 specimens collected from women without any ovarian pathology (34 pre- and 5...

BACKGROUND This study was undertaken to evaluate whether or not pretreatment serum biochemical markers are prognostic factors for prostatic cancer with bony metastasis in patients on hormonal treatment. METHODS Between 1983 and 1998, 127 patients with prostatic cancer and bony metastasis were included for evaluation. Serum prostate-specific antigen, alkaline phosphatase, calcium (Ca), lactic ...

This study makes use of online teaching in this environment and adopts it for a required computer skills course with Cognitive apprenticeship (CA) Co-regulated learning (CRL) methods to improve students’ skills, motivation, experience learning. The subjects are first-year students non-information-related department at private university northern Taiwan. A total four classes comprising 111 parti...

BACKGROUND Early prognostication of neurological outcome in comatose patients after cardiac arrest (CA) is important for devising patient treatment strategies. However, there is still a lack of sensitive and specific biomarkers for easy identification of these patients. We evaluated whether molecular signatures from blood of CA patients might help to improve the prediction of neurological outco...

This study assessed the pulp healing response to human freeze-dried bone (FDB) in two cynomolgus monkeys using 36 noncarious primary teeth pulpotomized and randomly assigned to three medicaments. FDB was applied on the pulp stumps and covered with sterile tin foil as experimental group. The two other groups received either calcium hydroxide [Ca(OH)2], or IRM (reinforced ZOE). All teeth were res...

Background: Due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. However, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. So, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s...
