Spatiotemporal succession of phosphorous accumulating biofilms during the first year of establishment.

Many wastewater treatment plants are dependent on the utilization of microorganisms in biofilms. Our knowledge about the establishment of these biofilms is limited, particular with respect to biofilms involved in enhanced biological phosphorus removal (EBPR). These biofilms rely on polyphosphate-accumulating organisms (PAOs), requiring alternating oxic and anaerobic conditions for phosphorous uptake.

Acute and chronic effects of the organophosphate malathion on the pancreatic α and β cell viability, cell structure, and voltage-gated K currents.

Studies indicate that the pesticide malathion may have a role in diabetes. Herein, we determined the effects of different concentrations of malathion on survival, ultrastructure, and electrophysiologic islet cell parameters. Acutely, high concentrations of malathion (0.

Spatial fractionation of phosphorus accumulating biofilm: stratification of polyphosphate accumulation and dissimilatory nitrogen metabolism.

The spatial distribution of microorganisms represents a critical issue in understanding biofilm function. The aim of the current work was to develop a method for biofilm fractionation, facilitating the analysis of individual spatial biofilm layers using metagenomic approaches. Phosphorus accumulating biofilm applied in an enhanced biological phosphorus removal wastewater treatment plant, were fractionated, and analyzed.

Feasibility of negative pressure wound therapy during intercontinental aeromedical evacuation of combat casualties.

Objective: The objective of this study was to assess the feasibility of utilizing negative pressure wound therapy (NPWT) for the treatment of wartime soft-tissue wounds during intercontinental aeromedical evacuation.

Background: Attempts to use NPWT during early phases of overseas contingency operations resulted in occasional vacuum system failures and potentially contributed to wound complications. These anecdotal episodes led to a perception that NPWT during aeromedical evacuation carried a high risk of wound complications and limited its use.

Disability levels of college-aged men with a history of Osgood-Schlatter disease.

Osgood-Schlatter disease (OSD), which is a traction apophysitis of the tibial tuberosity, is one of the most common orthopedic conditions that adolescent athletes will encounter. Adolescent athletes with OSD typically present with pain, swelling, and tenderness over the tibial tuberosity that worsens with athletic activity. Few published reports have described the effects of OSD on the disability levels of athletes beyond adolescence.
