The use of antibacterial drug combinations with synergistic effects is increasingly seen as a critical strategy to combat multi-drug resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA). In this work, the proteome responses in MRSA under the stress of a sub-inhibitory dose of a synergistic drug combination of a novel erythromycin derivative, SIPI-8294, and oxacillin, we...

The incidence of invasive fungal infections is increasing in recent years. The present study mainly investigated glabridin (Gla) alone and especially in combination with fluconazole (FLC) against Cryptococcus neoformans and Candida species (Candida albicans, Candida tropicalis, Candida krusei, Candida parapsilosis and Candida Glabratas) by different methods. The minimal inhibitory concentration...

INTRODUCTION Few published in vitro studies have shown antitumor drug action or possible synergistic effects of fluoroquinolones. To assess the potential role of combination therapy, cytotoxic effects of ciprofloxacin and epirubicin alone and in combination were determined. MATERIAL AND METHODS Human urothelial cancer cell lines HT1197 and HT1376 were exposed in vitro for 1 h to different con...

Objective(s): To evaluate the in vitro interaction between different extracts of Thymbra spicata L. and certain antimicrobial drugs of different mechanisms, including ampicillin, cefotaxime, amikacin and ciprofloxacin. This study was performed against multidrug-resistant strains of Staphylococcus aureus and Klebsiella pneumoniae. Materials and Methods: Evaluation of antibacterial activity and ...

BACKGROUND Hemangioma is the most common tumor of neonatal period and it is almost always appeared by the end of the first week of life and can be found mostly in head and neck area. This study evaluated the synergistic effect of bleomycin, triamcinolone and epinephrine in treatment of hemangioma and arte-riovenous malformations. METHODS In this multicenter study, a combination of bleomycin,...

BACKGROUND c-Met and EGFR receptors are widely expressed on cancer cells; they are implicated in the development and progression of cancer through a plethora of effects on cell cycle progression, apoptosis, motility and metastasis and are potential targets for combination therapy. EGFR receptor tyrosine kinases are currently being targeted in a number of malignancies. METHODS Apoptosis was st...

The synergistic hemolysis reactions of 61 reference strains and 189 clinical isolates representing 17 species of staphylococci were examined on plates of Trypticase soy blood agar (BBL Microbiology Systems, Cockeysville, Md.). Some or all of the strains of Staphylococcus aureus, S. epidermidis, S. capitis, S. cohnii, S. haemolyticus, S. hyicus, S. simulans, S. warneri, and S. xylosus produced a...

Synergistic combinations of antimicrobial agents with different mechanisms of action have been introduced as more successful strategies to combat infections involving multidrug resistant (MDR) bacteria. In this study, we investigated synergistic antimicrobial activity of Camellia sinensis and Juglans regia which are commonly used plants with different antimicrobial agents. Antimicrobial suscept...

Combinations of reverse transcriptase (RT) inhibitors are currently used in anti-human immunodeficiency virus therapy in order to prevent or delay the emergence of resistant virus and to improve the efficacy against viral enzymes carrying resistance mutations. Drug-drug interactions can result in either positive (additive or synergistic inhibition) or adverse (antagonistic interaction, synergis...

Ceramide (CE)-based combination therapy (CE combination) as a novel therapeutic strategy has attracted great attention in the field of anti-cancer therapy. The principal purposes of this study were to investigate the synergistic effect of CE in combination with docetaxel (DTX) (CE + DTX) and to explore the synergy mechanisms of CE + DTX. The 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium ...
