Preformed crowns for restoration of primary teeth are used in various treatments and are essential for restoring the crowns of primary molars. However, there are concerns that mechanical, chemical, and thermal stimulation may cause release of components of such crowns. We examined systemic accumulation of heavy metals associated with preformed crowns (3M Stainless Steel Primary Molar Crowns) us...

The visibility restoration of images is effected by various kinds of weather conditions like fog, mist, sandstorm, rain etc. This poor visibility will cause failure in the image processing applications like video surveillance, object detection, object recognition, intelligent transportation etc. The traditional visibility restoration will not requisitely restore the hazy images, because of the ...

In the United States, when medical devices are associated with adverse events that result in death or serious injury, or have malfunctions that could lead to death/serious injury, these events must be reported to the Food and Drug Administration’s Center for Devices and Radiologic Health by device manufacturers and user facilities. However, the defects in the medical device evaluation process (...

“Restoration of (wheeled) mobility in SCI rehabilitation” was the theme of a recent International Congress in Amsterdam, April 2004. Restoration of mobility in spinal cord injury (SCI) in its ultimate form would be to remove the cause of the mobility limitation, i.e., curing the SCI. Despite a large and basic research effort on neural regeneration on spinal cord repair and on damage preventive—...

In some pattern recognition processes bmed on recognizing structural features, a serious problem is poorly-cbawn lines which cause broken parts when a digital bitmap (a binary image) is madeof the line-jgure. This broken pattern changes the pattern structure, and increases the likelihood of rejection or misreading during the recognition process. Therefore, we have developed a restoration method...

DNA lesions cause stalling of DNA replication forks, which can be lethal for the cell. Homologous recombination (HR) plays an important role in DNA lesion bypass. It is thought that Rad51, a key protein of HR, contributes to the DNA lesion bypass through its DNA strand invasion activity. Here, using model stalled replication forks we found that RAD51 and RAD54 by acting together can promote DNA...

Antibiotically disturbed gastrointestinal microbiota needs a long period time to be restored to normal, which may cause a series of problems to the host. The understanding of restoration of the biased microbiota by antibiotics remains largely unknown. Here, we investigated the microbiota shift in foregut (rumen) and hindgut (rectum) of lactating cows after antibiotics exposure as well as after ...

The aim of this paper was to conduct a systematic review of body fat distribution before and after partial and complete weight restoration in individuals with anorexia nervosa. Literature searches, study selection, method development and quality appraisal were performed independently by two authors, and data was synthesized using a narrative approach. Twenty studies met the inclusion criteria a...

Desiccation of the Aral Sea is one of the world's most serious ecosystem catastrophes. The cause of the Sea's degradation is massive, consumptive withdrawals of water from the Amu and Syr Daryas. Irrigation accounts for 94 percent of all consumptive uses and is situated over 8.5 million hectares of land across the Aral basin. At current rates of water use, the Aral will progressively decline in...

Shoreline armoring is prevalent around the world with unprecedented human population growth and urbanization along coastal habitats. Armoring structures, such as riprap and bulkheads, that are built to prevent beach erosion and protect coastal infrastructure from storms and flooding can cause deterioration of habitats for migratory fish species, disrupt aquatic-terrestrial connectivity, and red...
