The electro-Fenton process (EF) has faced major challenges, including mass transfer limitations. When the targeted pollutants are present in water at very low concentrations, degradation kinetics slower than desired, which leads to high energy consumption. To overcome this drawback, coupled adsorption on activated carbon (AC) and EF can be performed. Therefore, compounds preconcentrated AC befo...

The removal of 15 organic micro-pollutants (OMPs) in synthetic municipal wastewater was investigated in a laboratory-scale mesophilic anaerobic membrane bioreactor (AnMBR) using ultrafiltration and AnMBR followed by nanofiltration (NF), where powdered activated carbon (PAC) was added to enhance OMPs removal. No significant effects of OMPs spiking and NF connection on bulk organics removal and b...

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 pati...

background and aim: caffeine at low doses blocks adenosine receptors. these receptors are present in all parts of the body including auditory and vestibular system. this study aimed to evaluate the effects of caffeine on cervical vestibular evoked myogenic potential (cvemp). methods: in this interventional double-blind study, 40 cases (20 females and 20 males) aged 18-25 years were randomly ass...

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: Prepare a global overview of agro-industrial residues used for activated carbon (CA) production, seeking caffeine removal water bodies.
 
 Theoretical reference: Aiming the adequate understand involved processes, as well each stage when adsorption occurred. The theoretical concepts might help to analyse how important is pollution emerging contaminants in bodies, current env...

caffeine, an adenosine a1, a2a, and a2b receptor antagonist, is frequently used as an adjuvant analgesic in combination with non steroidal anti-inflammatory drugs or opioids. the aim of this study was to evaluate the effects of caffeine on preventing the development of morphine tolerance and analgesia in mice. in this study, different groups of mice received morphine (30 mg/kg) + saline (10 ml/...

Several performance-enhancing or ergogenic drugs have been linked to both significant adverse cardiovascular effects and increased risk. Even with scrutiny on the governance of (PEDs) in professional sport heightened awareness associated risk, there are some who prepared risk their use gain competitive advantage. Caffeine is most commonly consumed drug world its properties reported for decades....

background: the development of resistance to antimicrobial agents is a major problem in chemotherapy. finding agents which potentiate antimicrobial activity could be favorable. there are some reports that methylxanthines changed the inhibitory effect of antibacterial agents. thus, possible synergistic effect of methylxanthines, aminophylline and caffeine on some antibiotics, carbenicillin, ceft...
