have elevated levels of thyroid hormones (Barron, 1986; Hoar, 1988; Datta et al., 1999; Eales, 1990). Thyroid hormones play a central role in controlling many of the alterations in physiology, morphology and behavior noted during this metamorphic transition in juvenile salmon (Hoar, 1988). Thyroid hormones have also been identified in altering the visual system during smoltification. During mig...

‘Cause and effect’ relations between nutrition and susceptibility to infection on natural diets have rarely been demonstrated in any species. Such associations might be anticipated since the body responds to infection with considerable changes in protein metabolism (Baracos, 1986), basal metabolic rate (Chandra, 1980) and trace element distribution (Beisel et uf. 1973), indicating that the disp...

Clostridium hemolyticum was first described by Vawter and Records (J. Am. Vet. Med. Assoc., 68, 494, 1926) who found it to be the causative agent of bovine hemoglobinuria in Nevada, and who named it Clostridium hemolyticum bovis. Sordelli et al., (Compt. rend. soc. biol., 106, 142, 1931) in Chile, isolated from cattle afflicted with a similar disease a pathogenic Clostridium which they consider...

Advances in pharmacological agents and surgical and laser technology have had significant effects on the practice of ophthalmology in recent years. The widespread recognition and use of anti‐vascular endothelial growth factor (anti‐VEGF) drugs, as intravitreal injections, started with the treatment of age related macular degeneration (ARMD) several years ago. This is now standard treatment and ...

The culture and manufacturing of the cotton fabric used to make your Jeans’ may have implied the use of fertilizers or pesticides polluting a water basin, have led to relocating people and even of children labour at different stages of its fabrication. As a consumer you probably didn’t take all these consequences into account (for your sake most of the information is not available, or value-wis...

Using a new radio sample, 6C* designed to find radio galaxies at z > 4 along with the complete 3CRR and 6CE sample we extend the radio galaxy K − z relation to z ∼ 4.5. The 6C* K − z data significantly improve delineation of the K − z relation for radio galaxies at high redshift (z > 2). In a spatially flat universe with a cosmological constant (ΩM = 0.3 and ΩΛ = 0.7), the most luminous radio s...
