Weak Max+Max interactions can also be detected, but Myc+Myc homodimers do not form at physiological concentrations in vitro or in vivo.

Additional experiments using physiological concentrations of androgen (for example, 0.01 - 1 nM methyltrienolone) also failed to disclose any androgen-responsive genes (data not shown).

Thus, in the absence of physiological concentrations of PP5, GRs accumulate in the nucleus of A549 cells.

At physiological concentrations pristanic acid is a natural ligand for PPARα.

In contrast, under optimal anaerobic growth conditions, physiological concentrations of lactic acid inactivated the BV-associated pathogens without affecting the vaginal lactobacilli .

Transport is also inhibited by the chemical decynium-22 and physiological concentrations of corticosterone and cortisol.

In man, infusion of bile salts into the jejunum at physiological concentrations prolongs small bowel transit time and inhibits intestinal motor activity.

It has been shown that only physiological concentrations of insulin c. 30-40 μ U/ml are required for such an effect (De Fronzo, 1981).

In these studies, however, ABP (at least at physiological concentrations) appeared to be supportive, rather than detrimental, to spermatogenesis.

Study has shown that physiological concentration of orthosilicic acid stimulates collagen type 1 synthesis and osteoblastic differentiation in human osteoblast-like cells in vitro.
