1. Effects of chronic and prolonged solar radiation in immunologic system of fishermen from Recife, Brazil / Efeitos da radiação solar crônica e prolongada sobre o sistema imunológico de pescadores do Recife
Introduction: The ultraviolet radiation effects on the human immunological system are highly complex, disturbing some components of immune response. Objective: The objective of this study was to evaluate the clinical, histopathological and immunological effects from solar radiation in male fishermen with more than 10 years of uninterrupted activity. Methods:

2. Production of Aseptic Spores of Vesicular-Arbuscular Endophytes and Their Viability After Chemical and Physical Stress
The survival of germinating spores of vesicular-arbuscular endophytes after treatments with oxidizing agents, antibiotics, moist heat, ultrasonic radiation, and ultraviolet radiation was compared with that of their contaminating microbes. Spores of three species were rapidly decontaminated by treatment with 0.42% (wt/vol) chlorine available from 5.0% (wt/vol

3. Chromosomal Location and Properties of Radiation Sensitivity Mutations in Bacillus subtilis
Transformation and transduction crosses involving recA1, recB2, and urv-1 mutations have shown that these mutations belong to three distinct unlinked genetic loci. The precise position of these loci on the Bacillus subtilis chromosome map has been determined. The behavior of recB2 strains in transformation studies suggested a dominance of recB2+ function ove
