Glucocorticoid and thyroid hormones exert their effects in many body tissues by binding to their respective receptors. The search for possible cross-talking mechanisms in overlapping target cells led to the discovery of synergism between a thyroid hormone receptor-binding site and a cryptic glucocorticoid-responsive element. Glucocorticoid responsiveness could only be detected in the presence o...

INTRODUCTION Recent literature proposes that amyloid β (Aβ) and phosphorylated tau (p-tau) synergism accelerates biomarker abnormalities in controls. Yet, it remains to be answered whether this synergism is the driving force behind Alzheimer disease (AD) dementia. METHODS We stratified 314 mild cognitive impairment individuals using [18F]florbetapir positron emission tomography Aβ imaging and...

The detection of synergisms ± deviations from additive or linear behaviour ± is often an important step in uncovering mechanisms of biochemical processes. Yet, a theoretical background for systemic analysis of synergisms in metabolic networks is lacking. Based on suitable mathematical models, such a theoretical approach should allow predicting synergisms and analysing what mechanistic features ...

Background: Pseudomonas aeruginosa is the primary cause of infection with impaired defense mechanisms. P. aeruginosa commonly causes nosocomial infections and is the most common pathogen isolated from patients hospitalized for longer than 1 week. We examined the antimicrobial effect of multilayered carbon nanotubes on multi-drug-resistant. Materials and methods: In this research, 20 clinical i...

Previously we reported negative terata and c-mitosis synergism of FireMaster (polybrominated biphenyls) with colchicine in subacutely treated rats. Now we report absence of chromosome aberrations from FireMaster and absence of c-mitosis synergism of FireMaster and colchicine in male mice. For the study of chromosome aberrations groups of three mice received 0, 50, or 500 mg/kg FireMaster or 4.5...
