Data are presented which demonstrate acclimation of brown trout (Salmo trutta) to an acid medium. Sodium fluxes, transepithelial gill potentials and plasma electrolyte concentrations were measured in brown trout exposed to an acid medium of pH 6.0 for a period of 6 weeks. Sodium loss rates in acid exposed fish are reduced compared to normal fish, and sodium uptake in insensitive to external pH ...

This study was aimed to evaluate the effect of L-ascorbyl-2-polyphosphate as a dietary ascorbic acid source on blood parameters of Caspian brown trout (Salmo trutta caspius), including red blood cell (RBC) count, white blood cell (WBC) and WBC differential. A total number of 600 Caspian brown trout (9.6±0.6 g) fingerlings were randomly distributed in triplicates among five treatments each conta...

Flaxseeds have been recently in focus due to the antioxidant capacity of some of their compounds. However, there is a lack of easily accessible information concerning their activity against lipid oxidation in food systems. Therefore, the aim of the study was to determine the effect of defatted meals (DFM) and the aqueous extracts (AFE) obtained from brown and golden flaxseeds on lipid oxidation...

Basidiomycetes that cause brown rot of wood are essential biomass recyclers in coniferous forest ecosystems and a major cause of failure in wooden structures. Recent work indicates that distinct lineages of brown rot fungi have arisen independently from ligninolytic white rot ancestors via loss of lignocellulolytic enzymes. Brown rot thus proceeds without significant lignin removal, apparently ...

Recent studies have reported discordant gene trees in the evolution of brown bears and polar bears. Genealogical histories are different among independent nuclear loci and between biparentally inherited autosomal DNA (aDNA) and matrilineal mitochondrial DNA (mtDNA). Based on multi-locus genomic sequences from aDNA and mtDNA, we inferred the population demography of brown and polar bears and fou...

To test the roles of lipid oversupply versus oxidation in causing tissue lipid accumulation associated with insulin resistance/obesity, we studied in vivo fatty acid (FA) metabolism in obese (Obese) and lean (Lean) Zucker rats. Indices of local FA utilization and storage were calculated using the partially metabolizable [9,10-(3)H]-(R)-2-bromopalmitate ((3)H-R-BrP) and [U-(14)C]-palmitate ((14)...

Brown-rot decay results in rapid reduction in degree of polymerization of holocellulose, with concomitant strength loss without removing lignin. Development of new methods of wood protection will require focusing on early events in the sequence of fungal attack during colonization. Pit membranes (sapwood) of wood cell walls represent a readily available source of nonlignified carbohydrate, i.e....

A new species, Porphyromonas canoris, is proposed for black-pigmented asaccharolytic strains isolated from subgingival plaque samples from dogs with naturally occurring periodontal disease. This bacterium is an obligately anaerobic, nonmotile, non-spore-forming, gram-negative, rod-shaped organism. On laked rabbit blood or sheep blood agar plates, colonies are light brown to greenish brown after...

In April 2002 and 2003, soft rot on fruit of eggplant (Solanum melongena) caused by Choanephora cucurbitarum was observed in the experimental fields at Gyeongnam Agricultural Research and Extension Services in Korea. The disease began with water-soaking and dark-green lesions, and then the infected tissues were rapidly rotten. Sporangium was subglobose in shape and sized 40~130 µm. Monosporous ...
