Colchicine, a potent neurotoxin derived from plants, has been recently introduced as a degenerative toxin of small pyramidal cells in the cortical area 1 of the hippocampus (CA1). In this study, the effect of the alkaloid in CA1 on the behaviors in the conditioning task was measured. Injections of colchicine (1,5 μg/rat, intra-CA1) was performed in the male Wistar rats, while the animals were s...

introduction: one of the hallmark symptoms of posttraumatic stress disorder (ptsd) is the impaired extinction of traumatic memory. single prolonged stress (sps) has been suggested as an animal model of ptsd, since sps rats exhibited the impaired fear extinction. oxytocin (oxt) has been recently suggested as a potential pharmacotherapy for treatment of ptsd. in this study, using sps rats we inve...

introduction: biological effects of magnetic fields have been investigated by scientists for many years and a vast amount of research using different frequencies and intensities have been performed on humans and laboratory animals. the results of these studies, which have mostly been done by applying high frequencies, have shown that electromagnetic fields are effective on structure and functio...

Background: The aim of this study is to investigate the clinical acceptability color change that may occur in time about full ceramic materials used for aesthetic restorations, which are bonded after different surface conditioning processes, by measuring with spectrophotometer.
 Methods: lithium disilicate CAD material we our work was prepared isomet form 1-millimeter-thick specimens. Thre...

background: polymerization of resin‑modified glass‑ionomers (rmgis) is mediated through two competing mechanisms: an acid‑base reaction and a light‑dependent resin polymerization. furthermore, pre‑conditioning with acid has resulted in an increase in enamel bond strength of some rmgis. this in vitro study evaluated the effect of pre‑conditioning and/or delayed irradiation on bond strength of th...

INTRODUCTION Horizontal supraglottic laryngectomy (HSL) allows the preservation of a functioning larynx and avoids a permanent tracheostoma. Its use and training have been conditioned by the employment of organ preservation programs and endoscopic laser surgery. OBJECTIVE To show functional and oncological long-term results of HSL. MATERIAL AND METHOD 110 patients treated with HSL with a mi...

Objective: This study compares different surface conditioning methods applied to various composite surfaces in order investigate the possible effects on composite-ceramic bond strength. It was aimed increase strength between flowable which is frequently used immediate dentin sealing procedure and ceramic surfaces. Material Methods: Eighty eighty conventional discs were prepared with five discs....
