an air–assisted liquid–liquid microextraction method for the extraction and preconcentration of trace amounts of some synthetic phenolic antioxidants in biological fluids followed by their determination by gas chromatography–flame ionization detection has been reported. in this method the target analytes are extracted into a few microliters of carbon tetrachloride (extraction solvent) from an a...

Objectives Mandibular third molar extraction is among the most commonly performed dental procedures. Fracture of the angle of mandible after third molar extraction is a rare complication of this procedure. Case Herein, we report fracture of the right angle of mandible immediately after extraction of mandibular right third molar in a 38-year old healthy female patient, which was surgically mana...

aim : the aim of this survey was to compare four dna extraction methods from iranian sheep strain e.granulosus isolates. background : cystic echinococcosis (ce) caused by the metacestode of the dog tapeworm echinococcus spp., is a global zoonotic infection which is economically important and constitutes a major threat to public health in many countries. strains characterization is essential for...

introdouction: injection of local anesthesia during dental procedures can induce metabolic changes. the purpose of this study was to evaluate the changes in the serum blood glucose levels after the injection of lidocaine with a vasoconstrictor during tooth extraction. materials and methods: in this clinical trial study, we enrolled 60 patients. we extracted mandibular teeth by using inferior al...

We reported a 75-year-old diabetic man, who developed opacification and neovascularization of the posterior capsule after extracapsular cataract extraction and posterior chamber intraocular lens implantation. The patient was treated with two injections of 2.5 mg of intravitreal bevacizumab. The treatment produced an important regression of the posterior capsular new vessels, allowing us to perf...

Unoperated cataract in the developing world remains ophthalmology's major unsolved problem. Recent developments have brought into question the assumptions of those who have thought that extracapsular surgery with implantation of a posterior chamber intraocular lens is an unrealistic approach to the treatment of global cataract blindness. High-quality 1-piece posterior chamber intraocular lenses...

OBJECTIVE To investigate the effect of cataract extraction on the visual fields of patients with open-angle glaucoma. METHODS Patients in a prospective cohort study in a tertiary center underwent standard automated perimetry every 6 months. We compared the mean results of the 2 examinations immediately before and 2 examinations immediately after phacoemulsification cataract extraction and int...

There has been a dramatic rise in the frequency of cesarean sections, surpassing 30% of all deliveries in the US. This upsurge, coupled with a decreasing willingness to allow vaginal birth after cesarean section, has resulted in an expansion of the use of vacuum assistance to safely extract the fetal head. By avoiding the use of a delivering hand or forceps blade, the volume being delivered thr...

PURPOSE To evaluate visual outcomes, eye movement abnormalities, and postoperative complications after secondary posterior chamber intraocular lens (IOL) implantation in aphakic children who had initial LAC correction. METHODS A retrospective study was carried out on 53 patients (94 eyes). Following aphakic surgery and LAC correction the patients received secondary IOL implantation in the pos...
