Replacement of gluteal implants by polymethyl methacrylate filler: case report.

Silicone prostheses are an alternative to shape the buttock but further studies are still needed to support the effectiveness of its use. A patient sought medical attention for being dissatisfied with the glutaeal silicone prostheses inserted using subcutaneous technique four years before. The treatment adopted was prosthesis removal surgery, and subsequent filling with PMMA.

Microbial quality of soil from the Pampa biome in response to different grazing pressures.

The aim of this study was to evaluate the impact of different grazing pressures on the activity and diversity of soil bacteria. We performed a long-term experiment in Eldorado do Sul, southern Brazil, that assessed three levels of grazing pressure: high pressure (HP), with 4% herbage allowance (HA), moderate pressure (MP), with 12% HA, and low pressure (LP), with 16% HA. Two reference areas were also assessed, one of never-grazed native vegetation (NG) and another of regenerated vegetation after two years of grazing (RG).
