Among Acinetobacter species, A. baumannii and other closely related species are commonly implicated in nosocomial infections. These organisms are usually multidrug resistant (MDR), and therapeutic options to treat A. baumannii infections are very limited. Clinicians have been resorting to older antimicrobial agents to treat infections caused by MDR A. baumannii, and some of these agents have do...

AIM This study was conducted to determine the prevalence and antimicrobial susceptibility of Streptococcus suis and their resistance patterns isolated from both clinically healthy carriers and diseased pigs in and around Guwahati, Assam, India. MATERIALS AND METHODS A total of 497 samples were collected during October, 2012, to April, 2014, from clinically healthy (n=67) and diseased (n=230) ...

UNLABELLED Dental roots that have been exposed to the oral cavity and periodontal pocket environment present superficial changes, which can prevent connective tissue reattachment. Demineralizing agents have been used as an adjunct to the periodontal treatment aiming at restoring the biocompatibility of roots. OBJECTIVE This study compared four commonly used demineralizing agents for their cap...

A study was conducted to evaluate in vitro the effect of root surface conditioning with basic fibroblast growth factor (b-FGF) on morphology and proliferation of fibroblasts. Three experimental groups were used: non-treated, and treated with 50 microg or 125 microg b-FGF/ml. The dentin samples in each group were divided into subgroups according to the chemical treatment received before applicat...

Fifty coconut palms exhibiting early symptoms of lethal yellowing were selected for treatment with oxytetracycline-HCl, tetracyclineHC1, streptomycin nitrate, potassium penicillin-G, or griseofulyin. Two grams of antibiotic in 0.2 or 1.0 liters of water were pressure injected into the trunk of each tree except for the griseofulvin treatments which were applied as a paste into holes bored in the...

OBJECTIVE The aim of this study was to compare subgingival irrigation with tetracycline hydrochloride (TTC-HCL) as adjunctive treatment to scaling and root planning (SRP) on induced periodontitis in rats. MATERIAL AND METHODS In 60 rats, periodontal disease was ligature-induced at the mandibular left first molar. After 7 days, the ligature was removed and all animals were submitted to SRP, an...

The design, preparation and application of three-dimensional (3D) printed structures have gained appreciable interest in recent times, particularly for drug dosage development. In this study, the electrohydrodynamic (EHD) printing technique was developed to fabricate aligned-fiber antibiotic (tetracycline hydrochloride, TE-HCL) patches using polycaprolactone (PCL), polyvinyl pyrrolidone (PVP) a...

A facile, robust approach to the synthesis of Fe3O4/rGO/TiO2 nanocomposites is described. The synthesis involves two major steps: (1) preparation of Fe3O4/GO by an electrostatic self-assembly method; (2) deposition of TiO2 on the surface of the Fe3O4/rGO nanocomposite via a hydrothermal method. The asprepared Fe3O4/rGO/TiO2 photocatalyst exhibited an enhanced photocatalytic activity for the deg...
