Ecological restoration has been receiving enormous attention in recent years. The National Research Council book Restoration of Aquatic Ecosystems: Science, Technology, and Public Policy (Washington, DC:National Academy Press, 1992) received substantial and widespread publicity from the news media on its release, as well as substantive attention from the scientific community. A new journal, Res...

The presentation of patients with dental restorations that exhibit minor defects is one of the commonest clinical situations in the practice of general dentistry. The repair of such restorations, rather than replacement, is increasingly considered to be a viable alternative to replacement of the defective restoration. This paper considers factors influencing the repair of direct restorations, i...

Pelvic discontinuity represents a rare but challenging problem for orthopaedic surgeons. It is most commonly encountered during revision total hip replacement, but can also result from an iatrogentic acetabular fracture during hip replacement. The general principles in management of pelvic discontinuity include restoration of the continuity between the ilium and the ischium, typically with some...

Rapid restoration of flow into the true lumen and obliteration of a false lumen is considered the optimal approach to treating malperfusion syndrome due to acute aortic dissection. However, organ malperfusion can occasionally persist after proximal aortic graft replacement despite redirecting blood flow into the true lumen. A 35-year old man underwent the modified Bentall procedure for Stanford...

Heart has long been considered a terminally differentiated organ. Recent studies, however, have suggested that there is a modest degree of cardiomyocyte (CM) turnover in adult mammalian heart, albeit not sufficient for replacement of lost CMs following cardiac injuries. Cardiac regeneration studies in various model organisms including zebrafish, newt, and more recently in neonatal mouse, have d...

Concern over historic wetlands loss led to a national goal of no net loss (NNL) of wetlands acres and their environmental services. In support of the NNL goal, the US Army Corps of Engineers (Corps), under authority granted by Section 404 of the Clean Water Act, reviews permits to discharge fill material into wetlands. A permit review process called sequencing requires a permit applicant (permi...

The clinical application of multiple implant-supported restorations in edentulous jaws has proven to be a predictable long-term treatment (1, 2). The implant-supported restoration has also been proposed for the replacement of the single tooth (48). The single-tooth implant restoration has changed treatment planning of the missing tooth in the anterior sextant. Clinical situations in which singl...

In this paper, a restoration approach for noisy image is proposed where a boundary resetting boundary discriminative noise detection (BRBDND) and a median filtering with smallest window (MFSW) are applied. In the proposed image restoration approach, two stages are involved: noise detection and noise replacement. The BRBDND is used to detect noisy pixels in an image. If a pixel is uncorrupted, t...

BACKGROUND There are a number of indications for total joint replacement surgery, mainly degenerative changes with limited function, rheumatoid arthritis, post-traumatic changes, arthropathy accompanying rotator cuff injuries. Problems in the rehabilitation of patients following partial or total shoulder joint replacement surgery result from the anatomy and biomechanics of the shoulder, includi...
