Dynamics of IgG in the blood serum of sheep with different selenium intake

open access: yesVeterinární Medicína, 2008
An experiment was conducted to study the effect of supplementation of ewes with selenium in an inorganic and organic form on the level of IgG during infertility, pregnancy and lactation and in their offspring until two months of age. Control Group C (n =

Investigation of microalgal tolerance and growth in simulated tailings pond water containing naphthenic acids

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Oil sands tailings ponds, such as those in northeastern Alberta, present environmental challenges due to slow sedimentation, water entrapment, and toxic naphthenic acids (NAs), which hinder water reclamation. This study assessed the tolerance and biodegradation potential of Chlorella vulgaris (C.

Effect of the source and level of carotenoids in diets on their retention in eggs

open access: yesCzech Journal of Animal Science, 2017
The lutein and zeaxanthin deposition in egg yolks of hens was evaluated. The effects of various levels of extracts from Mexican marigold flowers in hen diets were compared in Experiments 1 (from 0 to 350 mg/kg) and 2 (from 0 to 950 mg/kg).

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

open access: yesIntegrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

The Individual and Combined Effects of Warming and Atrazine on Lithobates pipiens Phenotypes: Implications for Frog Declines

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Amphibians are the most threatened vertebrate class globally. Climate change, agrochemicals, and/or pathogens and parasites are implicated in contributing to amphibian declines, either singly or in combination. We investigated individual and combined effects of elevated temperatures and atrazine (2.0 μg/L) on Lithobates [formerly Rana] pipiens
