This study assessed the involvement of NMDA and group I metabotropic glutamate receptors, and tachykinin NK1 and NK3 receptors, in central sensitization of withdrawal reflexes in the decerebrated rabbit. Reflexes evoked in the ankle flexor tibialis anterior and the knee flexor semitendinosus by electrical stimulation at the base of the toes were enhanced(More)
According to a number of studies, between 40% and 60% of acute traumatic spinal cord injury (SCI) patients demonstrate cognitive dysfunction resulting from various forms of cerebral damage, including concurrent or premorbid closed head injury, chronic alcohol or substance abuse, and other causes. However, applicability of findings from these reports has(More)
BACKGROUND "Vascular depression" has recently been proposed. It is characterized by magnetic resonance imaging (MRI) T2-weighted subcortical lesions, a late onset of first episode of depression, and reduced heritability; a cerebrovascular etiology is suggested. The validity of "vascular depression" might be strengthened if an association was found between(More)
OBJECTIVE The effect of minor orthopaedic day surgery (MiODS) on patient's mood. METHODS A prospective population-based cohort study of 148 consecutive patients with age above 18 and less than 65, an American Society of Anaesthesiology (ASA) score of 1, and the requirement of general anaesthesia (GA) were included. The Medical Outcomes Study - Short Form(More)
Factors which have been causally related to neuropsychological deficits in acute spinal cord injury (SCI) patients include advanced age, limited educational level, acute traumatic brain injury, alcohol and/or substance abuse. Concomitant depression may impair motivation, prolong reaction time, and produce fatigue during neuropsychological testing, resulting(More)
Sternopygus macrurus of both sexes were injected with human chorionic gonadotropin (hCG) or saline. Electric organ discharge (EOD) frequency rose after hCG injections in females and gradually declined to baseline levels over the next few weeks. EOD changes in males were more complex and variable; most males showed an initial minor rise in EOD frequency(More)
We present a rare case of an ectopic main right renal artery originating as part of the coeliac axis. Renal arteries are usually paired vessels which originate directly from the aorta to supply each kidney. Variations in their origin and numbers have been reported by many authors. However, there has only been one previous report of a left main renal artery(More)
