(C ) Accumulation of lipids in myobundles, evaluated by Oil Red O stain, was absent from controls, moderate at lower concentrations, and considerable at higher concentrations of both statins (scale bar = 50 µm).
In conclusion, the bromoxynil, chloroxynil, and ioxynil showed only moderate cytotoxic effects at concentrations several times higher than their limits allowed in the drinking water.
This is in agreement with recent experimental human studies that found only weak irritation effects and moderate odor effects at concentrations up to 50 ppm (CTWA) (Muttray et al. 2007; van Thriel et al. 2010).
Key: - Not present; +, present at low concentration; ++, present at moderate concentration; +++, present at high concentration Key: -, No inhibition.
PhTX-I induces in vivo myotoxicity, moderates footpad edema (at concentrations up to 10 μg/mL and 0.5 μg/mL, resp ., and causes in vitro neuromuscular blockade in chick biventer cervicis muscle preparations (at concentrations of 1.4 μM).
Resins prepared from the BMI/azine and BMIN-oxide systems have lower thermal stability than the neat resin but differences are moderate at low additive concentrations.
At moderate concentrations, these neurotransmitters facilitate cognition but at high levels, they inhibit prefrontal activity while facilitating sensory cortices activity.
Chemical denaturation by guanidine HCl (GuHCl) of human carbonic anhydrase II (HCA II) leads to a three-state unfolding process (Cm,NI=1.0 and Cm,IU=1.9 M GuHCl) with formation of an equilibrium molten-globule intermediate that is stable at moderate concentrations of the denaturant (1 2 M) with a maximum at 1.5 M GuHCl.
Through the above measures, apoptosis was found to be induced at moderate concentrations of KA (0.5 pM and 50 nM) and necrosis at high concentrations (5 μM) in rat cortical cells.
At moderate concentrations, there is a possibility that inorganic ions enhance ethanol production in a similar way as moderate concentrations of aliphatic acids do.
