Renal Mass and Localized Renal Cancer: AUA Guideline.

Purpose: This AUA Guideline focuses on evaluation/counseling and management of adult patients with clinically localized renal masses suspicious for cancer, including solid-enhancing tumors and Bosniak 3/4 complex-cystic lesions.

Materials And Methods: Systematic review utilized research from the Agency for Healthcare Research and Quality and additional supplementation by the authors and consultant methodologists. Evidence-based statements were based on body of evidence strength Grade A/B/C (Strong/Moderate/Conditional Recommendations, respectively) with additional statements presented as Clinical Principles or Expert Opinions.

Histological response to titanium endodontic endosseous implants in dogs.

Endodontic endosseous implants stabilize teeth that have crown-root ratios compromised by periodontal disease, trauma, or apical resorption. By increasing the crown-root ratio, the implant improves the prognosis of the tooth, thus increasing its longevity. The purpose of this study was to evaluate, in vivo, the healing response to a newly introduced titanium endodontic implant.

The dimensions of the human dentogingival junction.

This study examined the naturally occurring dimensions of the dentogingival junction in 10 adult human cadaver jaws. The connective tissue attachment, epithelial attachment, loss of attachment, and sulcus depth were measured histomorphometrically for 171 tooth surfaces. Mean measurements were 1.

Bacterial contamination of dental radiographic film.

Three types of paper-covered and one type of plastic-covered Kodak dental film were used to determine if bacteria could penetrate the coverings and contaminate the inner film. Films from each group were immersed for 30 or 120 seconds in high concentrations of known bacterial suspensions with or without 10% sterilized calf serum added to the incubation media. The plastic-covered film effectively excluded all bacteria, whereas the paper-covered film showed contamination with all organisms even at 30 seconds.

Protection of mice against fission neutron irradiation by WR-2721 or WR-151327.

Two phosphorothioate compounds, WR-2721 and WR-151327, were examined for their radioprotective efficacies against the effects of fission neutron irradiation in male and female mice. Within sex groups no significant difference in lethality at 30 or 100 days postirradiation was found between WR-2721 or WR-151327 pretreatment. The dose modification factors (DMFs) for male mice treated with either compound were 1.
