Rocuronium Bromide Inhibits Inflammation and Pain by Suppressing Nitric Oxide Production and Enhancing Prostaglandin E Synthesis in Endothelial Cells.

Purpose: Rocuronium bromide is a nondepolarizing neuromuscular blocking drug and has been used as an adjunct for relaxation or paralysis of the skeletal muscles, facilitation of endotracheal intubation, and improving surgical conditions during general anesthesia. However, intravenous injection of rocuronium bromide induces injection pain or withdrawal movement. The exact mechanism of rocuronium bromide-induced injection pain or withdrawal movement is not yet understood.

Voluntary wheel running ameliorates symptoms of MK-801-induced schizophrenia in mice.

Schizophrenia is a chronic and severe mental disorder characterized by the disintegration of cognitive thought processes and emotional responses. Despite the precise cause of schizophrenia remains unclear, it is hypothesized that a dysregulation of the N‑methyl‑D‑aspartate (NMDA) receptor in the brain is a major contributing factor to its development. Brain‑derived neurotrophic factor (BDNF) is a member of the neurotrophin family and is implicated in learning and memory processes.

Treadmill exercise inhibits hippocampal apoptosis through enhancing N-methyl-D-aspartate receptor expression in the MK-801-induced schizophrenic mice.

Schizophrenia is a severe mental disorder characterized by abnormal mental functioning and disruptive behaviors. Abnormal expression of N-methyl-D-aspartate (NMDA) receptor, one of the glutamate receptor subtypes, has also been suggested to contribute to the symptoms of schizophrenia. The effect of treadmill exercise on schizophrenia-induced apoptosis in relation with NMDA receptor has not been evaluated.

Psychiatric rehabilitation of emotional disorders.

Emotional disorder is psychological and behavioral problems of emotional domain that is different from cognitive domain, such as thought and memory. Typical emotional disorders are anxiety disorder, depression, and bipolar disorder. In the present study, we discussed on the symptoms, progression, and treatment for the anxiety disorder (panic disorder, social phobia, and obsessive compulsive disorder), depression, and bipolar disorder.

Treadmill exercise improves spatial learning ability by enhancing brain-derived neurotrophic factor expression in the attention-deficit/hyperactivity disorder rats.

Attention-deficit/hyperactivity disorder (ADHD) patients show learning difficulty and impulsiveness. Exercise is known to improve learning ability and memory function. In the present study, we investigated the duration-dependence of the effect of treadmill exercise on spatial learning ability in relation with brain-derived neurotrophic factor (BDNF) expression in ADHD rats.

Treadmill exercise ameliorates disturbance of spatial learning ability in scopolamine-induced amnesia rats.

Alzheimer's disease is the most common neurodegenerative disease and this disease induces progressive loss of memory function Scopolamine is a non-selective muscarinic cholinergic receptor antagonist and it induces impairment of learning ability. Exercise is known to ameliorate memory deficits induced by various brain diseases. In the present study, we investigated the effect of treadmill exercise on spatial learning ability in relation with cell proliferation in the hippocampus using the scopolamine-induced amnesia mice.

Psychopathology of social isolation.

The most important defining factor of being human is the use of symbolic language. Language or communication problem occurs during the growth, the child will have a higher risk of social isolation and then the survival will be threatened constantly. Today, adolescents and youths are familiar with computer and smart-phone devices, and communication with others by these devices is easy than face-to-face communication.

Treadmill exercise ameliorates short-term memory disturbance in scopolamine-induced amnesia rats.

Purpose: Scopolamine is a nonselective muscarinic cholinergic receptor antagonist, which induces impairment of learning ability and memory function. Exercise is known to ameliorate brain disturbance induced by brain injuries. In the present study, we investigated the effect of treadmill exercise on short-term memory in relation to acetylcholinesterase (AChE) expression in the hippocampus, using a scopolamine-induced amnesia model in mice.

Treadmill exercise improves short-term memory by enhancing neurogenesis in amyloid beta-induced Alzheimer disease rats.

Alzheimer's disease is one of the most devastating neurodegenerative disorders, and this disease is characterized by severe memory impairment and decline of cognition. Hippocampal neurons are vulnerable to injury induced by Alzheimer's disease. Physical exercise is known to promote cell survival and functional recovery after brain injuries.

Treadmill exercise reduces spinal cord injury-induced apoptosis by activating the PI3K/Akt pathway in rats.

Apoptosis occurring secondary to spinal cord injury (SCI) causes further neural damage and functional loss. In this study, a rat model was used to investigate the effect of treadmill exercise on SCI-induced apoptosis and expression of neurotrophic factors. To produce SCI, a contusion injury (10 g × 25 mm) was applied subsequent to laminectomy at the T9-T10 level.

Impact of Several Types of Stresses on Short-term Memory and Apoptosis in the Hippocampus of Rats.

Purpose: Stress has a deteriorating effect on hippocampal function. It also contributes to symptom exacerbation in many disease states, including overactive bladder and interstitial cystitis/bladder pain syndrome. We investigated the effects of various types of stresses (restraint, noise, and cold) on short-term memory and apoptosis in relation with corticotropin-releasing factor (CRF) expression.

Exposure to music and noise during pregnancy influences neurogenesis and thickness in motor and somatosensory cortex of rat pups.

Purpose: Prenatal environmental conditions affect the development of the fetus. In the present study, we investigated the effects of exposure to music and noise during pregnancy on neurogenesis and thickness in the motor and somatosensory cortex of rat pups.

Methods: The pregnant rats in the music-applied group were exposed to 65 dB of comfortable music for 1 hour, once per day, from the 15th day of pregnancy until delivery.

The phosphodiesterase type-5 inhibitor, tadalafil, improves depressive symptoms, ameliorates memory impairment, as well as suppresses apoptosis and enhances cell proliferation in the hippocampus of maternal-separated rat pups.

Early adverse experiences resulting from maternal separation may lead to neuronal cell death and eventually cause memory impairment. Maternal separation has been used to create a valid animal model of early life stress and a depression-like syndrome. The phosphodiesterase (PDE)-5 inhibitor, tadalafil (Cialis), is a widely prescribed agent for the treatment of erectile dysfunction.

The Relationship between Empathy and Medical Education System, Grades, and Personality in Medical College Students and Medical School Students.

Purpose: This study investigated the relationship between empathy and medical education system, grades, and personality in medical college (MC) students and medical school (MS) students.

Methods: One hundred fifty-five MC students and 137 MS students participated in this study, completing questionnaires on sociodemographic data, Jefferson Scale of Empathy, S-version, Korean edition (JSE-S-K), and Temperament and Character Inventory (TCI).

Results: Reward Dependence (RD), Cooperativeness (C), and Self-directedness+ Cooperativeness (SC), which are subscales of the TCI, correlated significantly with JSE-S-K score.
