Detection of Multiple Antibiotic Residues in Turkish Pine and Blossom Honeys Using LC-MS/MS Method.

Due to the high demand for honey, beekeepers often feed the bees with antibiotics to protect honeybees against illnesses; the determination of veterinary drugs and their residues in bee products especially in honey is gaining importance. In this study, commercially available 15 different brands, a total of 22 honey (14 blossoms and 8 pines) samples obtained from 5 chain supermarkets in the city of Bingöl and Diyarbakır, Turkey were analysed for 29 antibiotic residues. These antibiotics belong to 10 different categories, including tetracyclines, aminoglycosides, macrolides, sulfonamides, fluoroquinolones, benzimidazoles, anthelmintic, amphenicols, quinolines, and oxazolidines.

Safety of IV pulse methylprednisolone therapy during breastfeeding in patients with multiple sclerosis.

Background: Women with multiple sclerosis (MS) experience an increased risk of relapse in the postpartum period. High-dose methylprednisolone is the first-line treatment for acute relapses.

Objectives: To determine the transfer of methylprednisolone into human milk in breastfeeding MS patients.

Evaluation of marginal fit of single implant-supported metal-ceramic crowns prepared by using presintered metal blocks.

Statement Of Problem: Recently, presintered metal blocks for nonprecious and precious metal implant-supported restorations have gained popularity in computer-aided design and computer-aided manufacturing (CAD-CAM) systems. However, few studies have evaluated the marginal discrepancy of implant-supported restorations made with these new alloy systems.

Purpose: The purpose of this in vitro study was to compare the milling-sintering method with the lost-wax and milling methods in terms of the marginal fit of implant-supported metal-ceramic restorations.

Effect of various surface treatments on the bond strength of porcelain repair.

This study evaluated the effect of surface treatments on the repair strength of composite resin on a feldspathic ceramic. Ninety ceramic specimens were divided into six groups. In the experimental groups, 4% hydrofluoric acid etching, Er:YAG laser irradiation, CO2 laser irradiation, airborne-particle abrasion, and silica coating were used as surface treatments.

Effect of pre-processing methods on bond strength between acrylic resin teeth and acrylic denture base resin.

Objectives: This study evaluated the effects of various pre-processing methods on the bond strength between resin and denture teeth.

Backgrounds: Debonding of acrylic resin teeth from denture base material is a problem for patients wearing complete dentures.

Materials And Methods: Four experimental groups (n = 30) were investigated by subjecting tooth-resin bonding to tensile loading.
