phytoremediation is an emerging green technology that uses plants and their associated microbes to remediate different environments contaminated with various pollutants. phytoremediation, as an effective soil remediation technology, has gained popularity in the past ten years both in developed and developing countries. the main goal of the current article is to improve the understanding of phyt...

Autologous bone marrow transplants for solid tumor treatment are severely limited by the potential presence of residual cancer cells in the reinfused bone marrow and can lead to future tumor recurrence. This article presents a novel method of removing carcinoma cells from bone marrow with contaminating cancer cells. This method is based on our previous studies demonstrating that carcinoma cells...

ABSTRACT In hot environments, collagen, which is normally targeted when radiocarbon ( 14 C) dating bone, rapidly degrades. With little other skeletal material suitable for C dating, it can be impossible to obtain dates directly on materials. A small amount of carbonate occurs in hydroxyapatite, the mineral phase bone and tooth enamel, has been used as an alternative collagen. Unfortunately, oft...

By definition osteomyelitis is a bacterial infection of bone and may lead to bone destruction (1). It may be acute or chronic and it is defined as hematogenous when it originates from a bacteremia and as contiguous focus when it originates from an infection in nearby tissue. In adults osteomyelitis is most often related to open fractures or to any surgical procedure affecting bone or its adjace...

v,' The authors report a follow-up study of 103 American soldiers who were treated for brain wounds at one neurosurgical facility in Vietnam. The estimated mortality after evacuation from the war zone was 6% to 8%. Severe brain wounds, meningitis, and pulmonary emboli accounted for the majority of the late deaths. Thirty-four per cent had post-debridement complications such as retained bone fra...

In 1998, the Aznalcóllar mine tailings dyke in southwestern Spain broke, flooding the Agrio-Guadiamar river system with acid tailings up to the borders of one of the largest breeding colonies of white storks in the western Palearctic, Dehesa de Abajo. Over the following years, a high proportion of nestlings developed leg defects not seen before the spill, prompting this study. Nestlings with de...

Simian virus 40 (SV40) is a DNA virus isolated in 1960 from contaminated polio vaccines, that induces mesotheliomas, lymphomas, brain and bone tumors, and sarcomas, including osteosarcomas, in hamsters. These same tumor types have been found to contain SV40 DNA and proteins in humans. Mesotheliomas and brain tumors are the two tumor types that have been most consistently associated with SV40, a...

Abstract We previously reported the development of an osteogenic bone filler scaffold consisting degradable polyurethane, hydroxyapatite, and decellularized bovine particles. The current study was aimed at evaluating use this as a means local antibiotic delivery to prevent infection in defect contaminated with Staphylococcus aureus . evaluated two formulations same component ratios but differin...
