Stephen Jay Gould14 wrote, “I always look to closing paragraphs as indications of a book’s essential character.” Although that may be germane for books, in the case of manuscripts, it may be just the reverse; it may be that Abstracts are the indications of the essential character of as are the indications of the essential character of a manuscript. The structure of the Abstract varies depending...

Streptococcus Pneumoniae suspension preparation S. Pneumoniae capsular type 6A (DBL6A) was previously described as a virulent strain (Briles et al., 1992). Hemoculture of mouse second passage isolates were provided by Dr. Denis Martin (ID Biomedical, Quebec, Canada) and a suspension of the provided culture in Todd Hewitt medium supplemented with 0.5% yeast extract (THY) was incubated at 37 o C ...

Wound bed preparation is a new approach that integrates proven concepts to build a platform for the treatment of chronic wounds. It organizes currently approved medical procedures and products into a holistic approach that can be used to evaluate and remove barriers to the wound-healing process. Removal of such barriers allows for optimal wound repair and healing. To address these barriers, a s...

Procedure 1. Place the specimen on a clean glass slide. Add 1 drop of 20% KOH. 2. Place the cover glass on top of the slide and gently press to get rid of any air bubbles. Blot excess solution from the finished slide preparation with the gauze. 3. Place slide on the microscope stage and start with a low-power (10 ×) examination. To make epithelial cells visible, reduce illumination by lowering ...

Robotic site preparation has been identified as an integral precursor to human landings on Mars. Many species of social insect carry out the site preparation task when they construct their nests. A site preparation algorithm was developed based on the nest construction behavior of a particular species of ant, Leptothorax albipennis. In this paper, we present a new approach to modeling the tempo...

Errors made during the sample preparative process contribute significantly to the total analytical error of immunoassays. Reduction in the magnitude of these errors have been made by improvements in the manualfluid handling systems and mechanization of the individual steps in the process. The mechanization has been stimulated by developments in both computing hardware and software. A laboratory...

Clinical guidelines for the care of patients with progressive chronic kidney disease (CKD) have been developed by a broad range of organizations within the kidney community. Despite consensus among these guidelines and significant effort on the part of federal agencies, voluntary health organizations, and professional groups, existing data suggest that much work remains to achieve acceptable le...

introduction: the aim of this in vitro study was to evaluate the effects of establishing glide path on the centering ability and preparation time of two single-file reciprocating systems in mesial root canals of mandibular molars. methods and materials: sixty extracted mandibular molars with curvatures of 25-39 degrees and separate foramina for the mesiobuccal and mesiolingual canals, were divi...

introduction: pulpectomy is the preferred treatment for restorable primary teeth with symptomatic irreversible pulpitis or periradicular lesion. considering the rather new application of rotary files for pulpectomy of primary teeth, the aim of this study was to compare the cleaning efficacy and instrumentation time of hand k-files and mtwo rotary system for preparation of human primary molars. ...

introduction: the aim of this study was to compare the formation of dentinal crack and craze lines in the root dentin during root canal preparation with three different niti endodontic systems, naming reciproc (rcp), protaper universal (ptu) and mtwo. methods and materials: one hundred extracted mandibular premolars with single canals were selected and decoronated. the teeth were randomly divid...
