1. AN EVALUATION OF THE THERMAL AND LUMINOUS ENVIRONMENT OF LAYING HEN AVIARIES EQUIPPED WITH LIGHT-EMITTING DIODE AND COMPACT FLUORESCENT LAMPS AND THEIR EFFECTS ON PRODUCTION AND EGG QUALITY
ABSTRACT The thermal and luminous conditions in aviaries affect the production and quality of eggs. Thus, the aim of the present study was to evaluate the thermal and luminous environment of commercial laying hen aviaries equipped with compact fluorescent (CF) and light-emitting diode (LED) lamps and their influence on egg production and quality. The study w

4. Structural basis of contraction in vitreal fibrous membranes.
A combined ultrastructural and immunofluorescent study was conducted on experimentally induced fibrous membranes in the vitreous of adult rabbits. Autochthonous tissue cultured fibroblasts were injected into the mid-vitreous of one eye of each of 25 rabbits. The animals were monitored routinely with an ophthalmoscope and slit-lamp and were killed at various
