Hypersensitivity Reaction to Local Anesthetic in Dentistry: A Case Report
Background and Aim: Local anesthesia plays an important role in dentistry. Although hypersensitivity reactions to local anesthetic drugs are rare,but they are more common in dental cartridge components. This study reports a rare case of hypersensitivity to components of local anesthesia cartridge. Case Report: A 61-year-old female patient referred to The Medical Council to complain the dentist ...
متن کاملVectorial proton transfer coupled to reduction of O2 and NO by a heme-copper oxidase.
The heme-copper oxidase (HCuO) superfamily consists of integral membrane proteins that catalyze the reduction of either oxygen or nitric oxide. The HCuOs that reduce O(2) to H(2)O couple this reaction to the generation of a transmembrane proton gradient by using electrons and protons from opposite sides of the membrane and by pumping protons from inside the cell or organelle to the outside. The...

هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولBacteriorhodopsin: a high-resolution structural view of vectorial proton transport.
Recent 3-D structures of several intermediates in the photocycle of bacteriorhodopsin (bR) provide a detailed structural picture of this molecular proton pump in action. In this review, we describe the sequence of conformational changes of bR following the photoisomerization of its all-trans retinal chromophore, which is covalently bound via a protonated Schiff base to Lys216 in helix G, to a 1...
متن کاملFull Vectorial Electric and Magnetic Fields
It is considered a dimensional reduction of Ue(1)× Ug(1) 3 + 1-dimensional electromagnetism to 2 + 1-dimensions. It is shown that all the six electric and magnetic field vectorial components are present in the reduced theory and that they can be described in terms of vector gauge fields. The quantum structure is maintained in the absence of boundary effects. In the case where boundary effects a...
