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...
The cause of airway smooth muscle (ASM) hypercontractility in asthma is not fully understood. The relationship of spontaneous intracellular calcium oscillation frequency in ASM to asthma severity was investigated. Oscillations were increased in subjects with impaired lung function abolished by extracellular calcium removal, attenuated by caffeine and unaffected by verapamil or nitrendipine. Whe...
Introduction: Damage to the central and peripheral nervous system causes neuropathic pain. Caffeine is a plant alkaloid and non-selective antagonist of A1, A2a and A2b adenosine receptors. It is reported that caffeine increases the threshold of pain. In this study, the effect of acute caffeine on behavioral responses of neuropathic pain was investigated. Materials and Methods: The present study...
Introduction and purpose: Post-activation potentiation (PAP) is the phenomenon by which muscular performance is enhanced in response to a conditioning stimulus. The purpose of this study was to compare the effects of PAP induced by resisted, accelerated and traditional plyometric with and without caffeine ingestion on competitive judokas performance. Materials and Methods: In a randomized, c...
The fate of 12 pharmaceutical pollutants was investigated to understand their removal mechanism during hospital wastewater (HWW) treatment in submerged membrane bioreactor (SMBR). High concentrations anti-depressant (venlafaxine and desvenlafaxine), analgesic (ibuprofen hydroxy-ibuprofen), caffeine were detected the HWW entire study period. SMBR showed high >70% antibiotics (sulfamethoxa...
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 recei...
Background: Caffeinated energy drinks are common drinks among athletes and general population that have benefits such as providing quick energy, reducing fatigue and creating alertness, but can lead to serious complications in patients, especially those who have cancer and mental, cardiovascular, or renal diseases. The aim of this study was to validate the quantitative analysis and determine ca...
Introduction: Research has shown that the time of day to absorb caffeine is an intervention variable which should be considered when evaluating caffeine ergogenic. The purpose of this study is to comprise sprint and endurance swimming records on female swimmers in the morning and evening following consumption of caffeine. Material and Methods: Fourteen female swimmers (age 24.6 ± 4 years, BMI 2...
This study aims to develop a predictive framework to assess the removal and fate of trace organic chemicals (TrOCs) during wastewater treatment by anaerobic membrane bioreactor (AnMBR). The fate of 27 TrOCs in both the liquid and sludge phases during AnMBR treatment was systematically investigated. The results demonstrate a relationship between hydrophobicity and specific molecular features of ...
Removal of Ca(2+) from tobacco suspension cell medium has two immediate effects on cytosolic Ca(2+) fluxes: (i) externally derived Ca(2+) influx (occurring in response to cold shock or hypo-osmotic shock) is inhibited, and (ii) organellar Ca(2+) release (induced by a fungally derived defense elicitor, caffeine, or hypo-osmotic shock) is elevated. We show here that the enhanced release of intern...
