Seasonal Variation in Culturable Bioaerosols in a Wastewater Treatment Plant.

Bioaerosols produced from Wastewater Treatment Plants (WWTPs) can pose health risks to plant workers and nearby inhabitants. There is a gap in air quality data for WWTPs in developing countries. The present study aimed to measure airborne bacterial and fungal concentrations in a WWTP in southwestern Iran between September 2015 and May 2016.

Abnormal ECG patterns in chronic post-war PTSD patients: a pilot study.

Background: Posttraumatic stress disorder (PTSD) is a psychiatric syndrome associated with high levels of sympathetic activation of the autonomic nervous system. Individuals diagnosed with PTSD have a high propensity for electrocardiogram (ECG) abnormalities, atrioventricular conductive defects, and cerebrovascular incidents.

Purpose: The aim of this study was to investigate ECG abnormalities in post-war PTSD patients.

Comparison of the dimensional accuracy of injection-molded denture base materials to that of conventional pressure-pack acrylic resin.

Purpose: This study compared the linear dimensional changes of 3 injection-molded denture base materials to that of conventionally processed polymethylmethacrylate (PMMA) resin.

Materials And Methods: An impression of an aluminum maxillary edentulous arch was made with a condensation silicone impression material (Denture Elasticon) to fabricate a gypsum master cast that was replicated as a silicone mold. A maxillary complete denture with acrylic teeth was waxed to full contour on the master cast and replicated to make 40 wax dentures.

Rehabilitation of severely eroded dentition utilizing all-ceramic restorations.

Tooth wear is becoming an increasing concern, particularly in younger patients. Clinicians will increasingly encounter such problems as more natural teeth are retained into older age and patients' aesthetic demands and expectations rise. The use of all-ceramic restorations has increased due to the materials' natural appearance and strength.
