Is botulinum toxin-induced focal paresis in mice unaffected by muscle activity?
This in vivo paradigm quantifies the degree of otherwise clinically inapparent botulinum toxin-induced focal calf muscle paresis. Increased muscle activity after low-dose injections does not influence the efficacy of botulinum toxin in normal muscles.
Glycomacropeptide- or alpha-lactalbumin-supplemented formula has no adverse effects on nutritional status in infant monkeys. Glycomacropeptide supplementation increases zinc absorption, which may permit the reduction of formula zinc concentrations, and alpha-lactalbumin supplementation promotes a plasma amino acid pattern similar to that of breastfed infant monkeys.
