In vitro susceptibility of e.faecalis and c.albicans isolates from apical periodontitis to common antimicrobial agents, antibiotics and antifungal me…

2012

The aim of this study was to evaluate in vitro antimicrobial activity of 4 antibiotic agents (for E.faecalis) and 4 antifungal agents (for C.albicans) by agar dilution method. Additionally, modified strip diffusion method was used for detection of in vitro antimicrobial activities of 5% NaOCl, 2.5% NaOCl, 17% EDTA and 2% CHX and agar diffusion method for detection of in vitro susceptibilities of three intracanal medicaments for 18 E.faecalis and 18 C.albicans isolates from primary and secondary root canal infection. Isolates were recovered from 231 endodontic samples of patients, with the need of root canal treatment and retreatment. All tested E.faecalis isolates showed resistance to antib…

Multi-particle azimuthal correlations in p-Pb and Pb-Pb collisions at the CERN Large Hadron Collider

2014

Measurements of multi-particle azimuthal correlations (cumulants) for charged particles in p-Pb and Pb-Pb collisions are presented. They help address the question of whether there is evidence for global, flow-like, azimuthal correlations in the p-Pb system. Comparisons are made to measurements from the larger Pb-Pb system, where such evidence is established. In particular, the second harmonic two-particle cumulants are found to decrease with multiplicity, characteristic of a dominance of few-particle correlations in p-Pb collisions. However, when a $|\Delta \eta|$ gap is placed to suppress such correlations, the two-particle cumulants begin to rise at high-multiplicity, indicating the prese…

Comportamento agronomico di quattro nuovi portinnesti ibridi pesco x mandorlo in un impianto ad alta densità in Sicilia

2009

The present study was aimed to evaluate the agronomic behavior of different rootstocks, recently licensed by the Dipartimento di Coltura e Difesa delle Specie Legnose of the University of Pisa, and tested in a high density planting system (2220 trees/ha). Trials were carried out in an experimental orchard established by the Dipartimento di Colture Arboree of the University of Palermo and located in Sicily (Sciacca – Agrigento – 150 m a.s.l.). The observations were carried out on clonal rootstocks: I.S. 5/8 (Polluce); I.S. 5/19 (Castore); I.S. 5/23; I.S. 5/29 and GF 677 grafted at dormant bud with the low chill requirement cultivar “Tropic Snow”. The orchard was established in 2004, trees we…

Histologic Evaluation of Human Intrabony Defects Following Non-Surgical Periodontal Therapy With and Without Application of an Enamel Matrix Protein …

2003

Background: Surgical periodontal treatment with enamel matrix protein derivative (EMD) has been shown to promote periodontal regeneration. However, it is not known whether nonsurgical periodontal therapy with additional subgingival application of EMD may also enhance periodontal regeneration. The purpose of this study was to clinically and histologically evaluate healing of human intrabony defects following non-surgical periodontal treatment with and without application of EMD. Methods: Sixteen patients, each of whom displayed one advanced intrabony defect around teeth or roots scheduled for extraction, were included in the study. The defects were treated as follows: 1) scaling and root pla…

The efficacy of 8% Arginine-CaCO3 applications on dentine hypersensitivity following periodontal therapy: a clinical and scanning electron microscopi…

2013

Objectives: Periodontal therapy is one of the etiological factors of dentine hypersensitivity (DH). This study aimed to evaluate the efficacy of %8Arginine-CaCO3 on DH that affects patients after periodontal treatment. Study design: Seventy-one teeth from the volunteers (n=36) with history of DH caused by periodontal therapy were included in this study, and randomly divided into two groups: group-1, who received 8%Arginine-CaCO3 and group-2, who received 1.23%NaF-gel. The clinical indices were recorded at first visit.DH was evaluated by using tactile, air-blast, and thermal stimuli. The subject’s response was recorded at baseline, immediately (Day-0) and one month after the application. Res…

Non-surgical management of chronic periodontitis with two local drug delivery agents-A comparative study

2011

Background: The selective removal or inhibition of pathogenic microbes with locally delivered antimicrobials when combined with scaling and root planing is often an effective approach for the managment of chronic periodontitis. Aim: To compare the clinical efficacy of tetracycline fibers and a xanthan based chlorhexidine gel in the treatment of chronic periodontitis. Methods and materials: Thirty systemically healthy patients in the age group of 30-50 years suffering from generalized chronic moderate periodontitis were selected. For each subject, two experimental sites were chosen that had probing depth >5mm and were located in symmetric quadrants and the sites were randomized at split mout…

Root canal disinfection of immature dog teeth with apical periodontitis: Comparison of three different protocols.

2014

Objectives: The present in vivo study was designed to assess the efficacy of 3 root canal disinfection protocols in immature dog teeth with apical periodontitis (AP). Material and Methods: Forty immature premolars with pulp necrosis and AP of five Beagle dogs were used. Three experimental disinfection protocols were established. After irrigation with 40 ml 5.25% sodium hypochlorite using the Endovac system, in Group 1 canals were flushed with QMix solution; in Group 2, canals were flushed with QMix solution and 2% chlorhexidine gel dressing was placed for two weeks; and in Group 3, triantibiotic paste dressing was placed for two weeks. Canals were sampled after periapical lesions were radio…

Cytotoxicity of isoflavones and biflavonoids from Ormocarpum kirkii towards multi-factorial drug resistant cancer.

2019

Abstract Background While incidences of cancer are continuously increasing, drug resistance of malignant cells is observed towards almost all pharmaceuticals. Several isoflavonoids and flavonoids are known for their cytotoxicity towards various cancer cells. Purpose The aim of this study was to determine the cytotoxicity of isoflavones: osajin (1), 5,7-dihydroxy-4ˈ-methoxy-6,8-diprenylisoflavone (2) and biflavonoids: chamaejasmin (3), 7,7″-di-O-methylchamaejasmin (4) and campylospermone A (5), a dimeric chromene [diphysin(6)] and an ester of ferullic acid with long alkyl chain [erythrinasinate (7)] isolated from the stem bark and roots of the Kenyan medicinal plant, Ormocarpum kirkii. The m…

Synergy assessment of fixed combinations of Herba Andrographidis and Radix Eleutherococci extracts by transcriptome-wide microarray profiling

2015

Abstract Background Generally accepted, but insufficiently proved, the concept of synergy is based on an assumption that combining of two biologically active substances is justified because the combination is more active and less harmful than the ingredients. Hypothesis Analysis of RNA microarray of isolated neuroglia cells and the comparison the number of genes deregulated by plant extracts and their fixed herbal formulation might be a useful tool/method for assessment of synergistic and antagonistic interactions of herbal extracts in human organism. Aim The primary aim of this study was to extend a new method of assessment of synergistic and antagonistic interactions of herbal extracts in…
