The recent credit crisis has heightened the awareness of credit risk among financial markets’ regulators and participants. However, despite the public discussion on centralized processing systems for the off-exchange traded (Over-The-Counter, OTC) transactions no research has been conducted on the factors that could explain their adoption among market participants. With this study, an attempt i...

The soft-agar overlay technique was originally developed over 70 years ago and has been widely used in several areas of microbiological research, including work with bacteriophages and bacteriocins, proteinaceous antibacterial agents. This approach is relatively inexpensive, with minimal resource requirements. This technique consists of spotting supernatant from a donor strain (potentially harb...

INTRODUCTION The aim of this study was to compare a clearing technique with conventional radiography in studying certain features of the root canal system in single root premolars. A secondary aim was to assess inter examiner agreement for these features using radiographs. MATERIALS AND METHODS Fifty-eight recently extracted single rooted premolars were included in this study. Two standard pe...

Noninvasive detection of skin microcirculation is very significant for clinical diagnosis and therapy of peripheral vascular disease. In this study, an optical clearing method enables a laser speckle contrast imaging (LSCI) technique to image dermal blood flow through intact rat skin. The optical clearing effect of rat skin in vitro caused by a mixture of PEG-400 and Thiazone is evaluated by a ...

introduction: the aim of the present in vitro study was to compare the accuracy of cone-beam computed tomography (cbct) in determining root canal morphology of mandibular first molars in comparison with staining and clearing technique. methods and materials: cbct images were taken from 96 extracted human mandibular first molars and the teeth were then evaluated based on vertucci’s classificatio...

OBJECTIVE Successful endodontic therapy depends on adequate mechanical and chemical debridement of the canal which requires knowledge of the canal morphology. Conventional radiography has been used to evaluate the canal type; however, direct digital radiography has recently been practiced for this purpose due to the shortcomings of conventional radiography. The aim of the present study was to c...

BACKGROUND The microvasculature is the network of blood vessels involved in delivering nutrients and gases necessary for tissue survival. Study of the microvasculature often involves immunohistological methods. While useful for visualizing microvasculature at the µm scale in specific regions of interest, immunohistology is not well suited to visualize the global microvascular architecture in an...

 Background and Objectives:Rapid processing of histopathological specimens and decreased turnaround time is important to fulfill the needs of clinicians treating sick patients, so the present study was conducted to compare the time taken and quality of sections in processing of prostatic tissue by rapid microwave and conventional techniques using morphometry. Methods: Four to five mm thick p...

Background: Clearing is an important step in the preparation of histological sections, that removes alcohol and other dehydrants from tissues prior to infiltration of the embedding material (usually paraffin wax).Different types of clearing agents are chloroform, Xylene, Toluene, Paraffin, Methyl benzoate and methyl salicylate & Citrus fruit oils.The commonly used clearing agent is xylene that ...
