Occurrence and removal efficiencies of fifteen pharmaceuticals were investigated in a conventional municipal wastewater treatment plant in Michigan. Concentrations of these pharmaceuticals were determined in both wastewater and sludge phases by a high-performance liquid chromatograph coupled to a tandem mass spectrometer. Detailed mass balance analysis was conducted during the whole treatment p...

In the present work, treatment of a mixture six emerging pollutants (acetamiprid, acetaminophen, caffeine, amoxicillin, clofibric acid and carbamazepine) by means photo-Fenton process has been studied, using simulated sunlight as an irradiation source. Removal these investigated in three different aqueous matrices distinguished amount chlorides (distilled water, 1 g L?1 NaCl 30 NaCl) at pH 2.8 ...

Induction of triploidy is one of the biotechnological methods in aquaculture used for genetic manipulation. It refers to a state where organisms have three complete sets of chromosomes instead of two and can result in sterility. Caffeine treatment that is safe and inexpensive, serve to induce triploidy in catfish. To suppress the second meiotic division, fertilized eggs were exposed to three di...

Previous studies have shown that caffeine has beneficial effects on cognitive impairment in sleep deprived male rats. Therefore in the present study, we examined the effects of chronic caffeine administration on learning and memory impairments induced by sleep deprivation (SD) in the intact and ovarectomized (OVX) female rats. Two sets of animals including intact and OVX were randomly recruited...

In this study, we investigated the impact of a controlled 4-day caffeine withdrawal period on the effect of an acute caffeine dose on endurance exercise performance. Twelve well-trained and familiarized male cyclists, who were caffeine consumers (from coffee and a range of other sources), were recruited for the study. A double-blind placebo-controlled cross-over design was employed, involving f...

In this study, hybrid ultrafiltration which involves adsorption onto activated carbon and/or coagulation was tested for the removal of ibuprofen, caffeine and diclofenac from municipal wastewater treatment plant effluent (c0 = 2–3 µg/L). Ultrafiltration in combination with powdered dose 5 mg/L separately or coagulants (FeCl3, 4 mg Fe (III)/L and, natural coagulant isolated bean seeds, 33 µL/L)....

This experiment was conducted to evaluate the effects of caffeine and trans-cinnamaldehyde (TC) on growth performance, hematological parameters, stress hormones, immune response, and some blood parameters of broiler chickens. Three hundred fifty 1-d-old broiler chicks were randomly assigned to 7 dietary treatments (five pens/ treatment of 10 male broilers each) in a completely randomized desig...

The presence of emerging organic contaminants (EOCs) in the environment is increasing and requires development technologies for their effective removal. Therefore, a literature review on behavior EOCs during municipal wastewater treatment, both major treatment systems particularly constructed wetlands (CWs), was carried out. study also reviewed anaerobic digesters (ADs) advanced oxidation proce...

Background: Caffeine is widely used for prevention of apnea and helps successful extubation from mechanical ventilation. It facilitates the transition from invasive to noninvasive support and reduces duration of continuous positive airway pressure (CPAP) in preterm infants. The optimum caffeine dose in preterm infants has not been well-studied in terms of benefits and risks. We compared efficac...
