Objectives—To assess respiratory morbidity over several cross sectional phases in the European carbon black manufacturing industry. Methods—Participants completed an amended (and translated) MRC respiratory morbidity questionnaire with additional questions on previous exposures, job history, etc, and spirometry traces in each phase. Concurrent with the health outcome measures, personal exposure...

Objectives Use of a reliable method to determine the degree of skeletal development of the mid-palatal suture is important in the choice of treatment between orthopedic maxillary expansion and surgical expansion in adolescents and young adults. The aim of this study was to review the new methods for evaluation of mid-palatal suture maturation. Methods Electronic search was conducted in PubMed ...

The erythemal exposure due to filtered ultraviolet radiation has been evaluated with a dosimetric spectrum evaluator in a glass enclosure to simulate a sun-room with glass roof and walls, in a greenhouse and in a small and large car. The ratio expressed as a percent of the erythemal irradiances to the shoulder of a person in an upright position inside each of the environments to those measured ...

BACKGROUND Advances in sunscreen technologies have yielded broad spectrum sunscreens at high-sun protection factor (SPF) and ultraviolet A protection factor (UVA-PF) levels that are photostable and powerful in protecting skin from erythema. Questions arise whether these sunscreens protect proportionally against cellular skin damage caused by high ultraviolet exposures. OBJECTIVE The objective...

Background & objectives: Work-related illnesses account for a large number of social problems. According to occupational therapists, occupational diseases are considered as life-threatening factors for workers. The aim of this study was to measure air pollution to suspended particles and to assess the health risk of PM2.5 and PM10 exposure in the textile industry. Methods: This analytical-cros...

feeding behavior of yellowfin seabream larvae during the first two weeks of larval life was studied by feeding larvae  on different ratios of live food and  microencapsulated diet (med). food consumption rate increased progressively with increasing larval weight. the results from visual observation of the larval guts under a light microscope indicated that yellowfin seabream larvae were able to...
