The purpose of this study was to evaluate the influence of the duration of interstitial laser acupuncture therapy effects on neurovegetative and neurobioelectrical parameters like heart rate (HR), heart rate variability (HRV), and electroencephalogram (EEG). We investigated 6 male Sprague-Dawley rats. They underwent 10 min, 20 min, and 30 min interstitial laser acupuncture (in randomized order,...

this blinded, randomized experimental study was designed to evaluate the analgesic effects of adding epinephrine or xylazine to lidocaine solution for brachial plexus block (bpb) in sheep. nine healthy, fat-tailed female lambs (26.6 ± 1.5 kg) were randomly allocated into three groups: lidocaine 2%, 5 mg kg-1 (lid, n = 6), lidocaine (5 mg kg-1) with epinephrine 5 µg ml-1 (lidep, n = 6) or lidoca...

introduction: considering the anticonvulsant effects of a1 adenosine receptors and the anatomical connections between pjriform cortex and amygdala, in this study, the role of a1 adenosine receptors activity of piriform cortex neurons on amygdala kindled seizures was investigated in rats. material and methods: the rats were fully kindled by daily electrical stimulation of amygdala. n6-cyclohexyl...

BACKGROUND Regional anesthesia techniques are increasingly preferred for caesarean section. The aim of the present study was to compare the anesthetic effects of levobupivacaine + fentanyl and bupivacaine + fentanyl on the mother and newborn during elective caesarean section under spinal anesthesia. METHODS In this prospective study, 50 gravidas, who were scheduled for cesarean section were e...

abstract competition is a phenomenon that influences the size, structure and stability of insect communities, particularly on solitary endoparasitoids species. although, competition normally incurs costs, it might be adaptive for the surviving individual. to determine which factors affect the patch use strategy of foragers under competition, the effect of previous experience with hosts already-...

BACKGROUND Anesthetic preconditioning (APC) is protective for several aspects of cardiac function and structure, including left ventricular pressure, coronary flow, and infarction. APC may be protective, however, only if the duration of ischemia is within a certain, as yet undefined range. Brief ischemia causes minimal injury, and APC would be expected to provide little benefit. Conversely, ver...

Introduction: Stereotactic body radiotherapy delivers hypofractionated irradiation with high dose per fraction through complex treatment techniques. The increased complexity leads to longer dose delivery times for each fraction. The purpose of this study is to investigate the impact of prolonged fraction delivery time with high-dose hypofractionation on the killing of cultured ACHN cells.Method...

The intent of this investigation was to examine the potential influence of varying durations of physical exertion at different times of the day on immediate mathematical performance by 120 sixth-grade boys and girls. Subjects were assigned to two control and two treatment groups (Solomon Four-group Design), with treated subjects administered physical exertion (paced walking at controlled modera...
