Over the past years, DNA biosensors have been developed to analyze DNA interaction and damage that have important applications in biotechnological researches. The immobilization of DNA onto a substrate is one key step for construction of DNA electrochemical biosensors. In this report, a direct approach has been described for immobilization of single strand DNA onto carboxylic acid-functionalize...

  Objective: Corrosion resistance is among the most important properties of metal alloys used in the oral cavity. Consumption of acidic foods reduces the salivary pH and intensifies the corrosion of brackets and orthodontic wires. This study aimed to compare electro galvanic corrosion of different orthodontic brackets and wires and determine the amount of ions released into acidic artifici...

  Objective: Orthodontic wires should have high resistance against corrosion in the oral environment. Since the effect of pH on corrosion has been well recognized, this study sought to assess and compare the electrochemical corrosion of orthodontic brackets and wires of different brands in acidic artificial saliva.   Methods: This in vitro experimental study was conducted on 24 mandibular centr...

A technique of directly measuring Venous Flow Rate (VFR) in a large superficial limbvein is described.With this technique, increases in VFR were noted in response to Epinephrine; and decreases inVFR, in response to the anticipation of, and the performance of an alerting mental arithmetic prob-lem.High Ego Strength Ss revealed higher rates of flow than low E.S. Ss at rest and...

Study 1 established either deliberative mind-set by having Ss contemplate personal change decision or implemental mind-set by having Ss plan execution of intended personal project. Ss were subsequently requested to continue beginnings of 3 fairy tales, each describing a main character with a decisional conflict. Analysis revealed that deliberative mind-set Ss ascribed more deliberative and less...

Table 1: The TAG table for a two-input AND gate. cir-unit delay uit power estimation run time % speed ss tp err. ss tp up s349 265. Run-time under a unit delay model: ss : using symbolic simulation, tp : using transition probability. cir-fixed binary inertial delay uit power estimation run time % speed ss tp err. ss tp up s349 231.

Besides lowering cholesterol, statins exert multiple effects, such as anti-inflammatory activity and improvement of endothelial cell function. We examined whether simvastatin (SS) protects against the development of elastase-induced pulmonary emphysema in mice by using mean linear intercepts of alveoli (Lm) as a morphometric parameter of emphysema. After injection of intratracheal elastase on d...

OBJECTIVE To evaluate the patterns of Ro autoantigen recognition in Korean patients with primary Sjögren's syndrome (SS) and to investigate its clinical significance in SS. METHODS Sera from primary SS (n = 51) and systemic lupus erythematosus (SLE) (n = 132) were tested by double immunodiffusion test and immunoblotting for reactivity with 60 kDa and 52 kDa Ro/SS-A proteins. Clinical manifest...

OBJECTIVES To determine the performance of different tear and salivary tests applied in Sjögren's syndrome (SS) and to disclose how these tests relate to common serologic tests in SS. DESIGN In addition to the routine ocular and oral tests for diagnosing SS (Schirmer test, rose bengal score, unstimulated whole saliva flow, and parotid sialography), tear breakup time and flow rate of glandular...

abstract biological and chemical changes in rhizosphere following organic residues as well as manures application are important processes which influence nitrogen mineralization and nutrients bioavailibity in soils. this study was done to evaluation of organic residues effect on growth, nitrogen supply and rhizosphere characteristics of corn and sunflower plants in greenhouse experiment using s...
