b a s e don folic acid biosynthetic pathway a mathematical model was made for bacterial growth to describe the synergistic effect between sulfamethoxazole and trimethoprim. The results obtained show a strong synergism at growth inhibiting concentrations of these two drugs. Two cyclic pathways included in the model are responsible for this synergism. The roles of these pathways in producing ...

The distinction between qualitative and quantitative interactions is stressed as it helps to elucidate differences between two current definitions of the term synergism and how multifactorial experiments should be designed, analysed statistically, and their results interpreted. Factorial design and analyses are strongly advocated so that interactions can be detected. It is suggested that intera...

Analgesics can be administered in combination with caffeine for improved analgesic effectiveness in a process known as synergism. The mechanisms by which these combinations produce synergism are not yet fully understood. The aim of this study was to analyze whether the administration of diclofenac combined with caffeine produced antinociceptive synergism and whether opioid mechanisms played a r...

Fludarabine-containing combinations have additive cell killing against leukemic blasts in vitro. It has also been shown that imatinib mesylate combined with fludarabine or cladribine had an additive effect on CML CFU-GM cells. In this regard, we aimed to investigate the effect of fludarabine-imatinib mesylate combination against CML blastic phase cell lines K562 and Meg-01. XTT test was perform...

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...

The DREAM challenge is a community effort to assess current capabilities in systems biology. Two recent challenges focus on cancer cell drug sensitivity and drug synergism, and highlight strengths and weaknesses of current approaches.

The potential for complex synergistic or antagonistic interactions between multiple stressors presents one of the largest uncertainties when predicting ecological change but, despite common use of the terms in the scientific literature, a consensus on their operational definition is still lacking. The identification of synergism or antagonism is generally straightforward when stressors operate ...

OBJECTIVE To study the synergism between neuropeptides and lithium ions. MATERIAL AND METHODS An experimental model of stroke (chronic bilateral occlusion of the common carotid arteries in rats), neuronal culture studies, histomorphological analyses, determination of micronutrient profile of brain substrates were used. RESULTS A complex of experimental studies revealed that the effect of ce...

Objective: Finding the synergism effect of miconazole and sulfametoxazole on 4 species of
