BACKGROUND AND OBJECTIVES The Analgesia Nociception Index is an index used to measure the levels of pain, sympathetic system activity and heart rate variability during general anesthesia. In our study, Analgesia Nociception Index monitoring in two groups who had undergone spinal stabilization surgery and were administered propofol-remifentanil (Total Intravenous Anesthesia) and sevoflurane-remi...

Nociception is one of the most complex senses that is affected not only by external stimulation but also internal conditions. Previous studies have suggested that circadian rhythm is important in modulating nociception. REV-ERBα knock-out (KO) mice have disrupted circadian rhythm and altered mood-related phenotypes. In this study, we examined the role of REV-ERBα in inflammatory nociception. We...

OBJECTIVE This study examined modulation of trigeminal pain/nociception by 2 supraspinal mechanisms: emotional controls of nociception and diffuse noxious inhibitory controls. BACKGROUND Prior research suggests emotional picture viewing (emotional controls) and tonic noxious stimuli (diffuse noxious inhibitory controls) engage supraspinal mechanisms to modulate pain and nociceptive processes....

plants from the genus phyllanthus like phyllanthus muellerianus have long been used in folk medicine for several ailments including fevers, toothache, dysmenorrhea, anemia and paralysis. despite these folkloric uses, there is little scientific data supporting the use of this plant in the management of pain. the purpose of this study is to evaluate the aqueous extract of the aerial parts of phyl...

the purpose of the present study was to evaluate anti-nociceptive effects of morphine, tramadol, meloxicam and their combinations in rats. seventy male wistar rats were divided into seven equal groups and randomly assigned to receive intraperitoneal saline (s) (control group, 1.0 ml kg-1), morphine (mo) (4.0 mg kg-1), tramadol (tr) (12.5 mg kg-1), meloxicam (ml) (1.0 mg kg-1), tramadol- morphin...

Genetic analysis of nociceptive behaviors in the nematode Caenorhabditis elegans and the fruit fly Drosophila melanogaster has led to the discovery of conserved sensory transduction channels and signaling molecules. These are embedded in neurons and circuits that generate responses to noxious signals. This article reviews the neurons and molecular mechanisms that underlie invertebrate nocicepti...

Nociception, warning of injury that should be avoided, serves an important protective function in animals. In this study, we show that adult Drosophila avoids noxious heat by a jump response. To quantitatively analyze this nociceptive behavior, we developed two assays. In the CO2 laser beam assay, flies exhibit this behavior when a laser beam heats their abdomens. The consistency of the jump la...

The assessment of articular nociception in experimental animals is a challenge because available methods are limited and subject to investigator influence. In an attempt to solve this problem, the purpose of this study was to establish the use of dynamic weight bearing (DWB) as a new device for evaluating joint nociception in an experimental model of antigen-induced arthritis (AIA) in mice. AIA...
