Tetracycline impregnated bone grafts in the management of -implantitis and guided bone regeneration around dental implants: A systematic review.

Background: Rehabilitation of dental arches with the help of dental implants has been revolutionary and a significant part of research is devoted to increasing its success rate. One of the most common causes of failure of dental implants is -implantitis caused due to microbial invasion. Newer strategies are being adapted for the treatment of -implantits and recent surgical management with the help of antibiotic-impregnated bone grafts shows a promising future.

LEPTOSPIROSIS IN URBAN AND SUBURBAN AMERICAN BLACK BEARS ( URSUS AMERICANUS) IN WESTERN NORTH CAROLINA, USA.

American black bear ( Ursus americanus) populations in North Carolina, US have recovered significantly in recent decades and now occupy much of western North Carolina, including urban-suburban areas. We used the black bear as a potential sentinel for leptospirosis, a bacterial zoonotic disease caused by Leptospira spp., which is maintained by domestic and wild mammals.

Buteo Nesting Ecology: Evaluating Nesting of Swainson's Hawks in the Northern Great Plains.

Swainson's hawks (Buteo swainsoni) are long-distance migratory raptors that nest primarily in isolated trees located in areas of high grassland density. In recent years, anthropogenic conversion of grassland habitat has raised concerns about the status of the breeding population in the northern Great Plains. In 2013, we initiated a study to investigate the influence of extrinsic factors influencing Swainson's hawk nesting ecology in north-central South Dakota and south-central North Dakota.
