The first principles were calculated to study the adsorption behaviors of caffeine molecules on the pristineand N-doped TiO2 anatase nanoparticles. Both oxygen and nitrogen in the caffeine molecule can reactstrongly with TiO2 nanoparticle. Thus, the binding sites were located on the oxygen or nitrogen atom ofthe caffeine, while the binding site of the TiO2 nanoparticle occurs ...

Background: Endometriosis is a common gynecological disease in which oxidative stress is a potential factor. Caffeine and caffeic acid are present in various foods and beverages with anti-oxidant, anti-inflammatory, and anti-carcinogenic properties. In this study, we aimed to investigate the ameliorative effects of caffeine, caffeic acid, and caffeine+caffeic acid treatments on oxidative stress...

some evidence indicates that caffeine consumption before exercise may affect muscular damage. the aim of this study was to investigate the effects of caffeine consumption (6mg/kg) following a session of resistance exercise on creatine kinase (ck) and lactate dehydrogenase (ldh) in active men. 20 male physical education students (age 21.22±1.25 years, height 175.13±6.88 cm, weight 69.22±7.10 kg ...

The effect of physiological concentrations of caffeine (purified from Persian tea) on adenosine deaminase (ADA) activity at physiological and pathological concentrations of adenosine (as substrate) in 50 mM Tris-HCl buffer (pH 7.3) at 37°C was investigated, using UV-VIS spectroscopy. ADA exhibited a bi-phasic activity behavior and both phases showed positive cooperativities indicating adenosine...

Objective: In recent years, there has been an increasing interest in using herbal products to overcome bacterial resistance. The aim of this study was to investigate the effect of lemon verbena aqueous extract, verbascoside and caffeine in combination with gentamicin against standard and clinical isolates of Staphylococcus aureus and Escherichia coli strains. Materials and Methods: The MIC and ...

  Objective: Non-steroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed pain control medications following periodontal surgery. This study aimed to compare the efficacy of three drug regimens namely celecoxib, celecoxib + caffeine and ibuprofen for pain relief following crown lengthening surgery.   Methods: This randomized, double blind clinical trial was performed on 45 pa...
