Does ability of Escherichia coli to produce hemolysis lead to a greater pathogenic effect on human sperm?
Results show a greater pathogenic effect on human sperm of E. coli strains with, versus without, hemolytic capacity.
Se-supplementation in healthy human adults with marginal Se status resulted in both beneficial and detrimental effects on cellular immunity to flu that was affected by the form of Se, supplemental dose and delivery matrix. These observations call for a thorough evaluation of the risks and benefits associated with Se-supplementation.
