In Ostariophysan fish, the detection of the alarm substance liberated into the water as a consequence of an attack by a predator elicits an alarm reaction or anti-predatory behavior. In this study, experiments were performed to: (i) describe and quantitatively characterize the behavioral and ventilatory responses in piauçu fish (Leporinus macrocephalus), individually and as part of a school, to...

BACKGROUND Family-centered rounds (FCR) are becoming the status quo for inpatient pediatric medical care; however, barriers still exist. The use of facilitators in FCR is gaining popularity. Although facilitators can increase comfort with FCR, the choice of preferred facilitator has not been studied by using rigorous methodology. In this study, we performed a randomized trial of facilitated FCR...

Behavioral tests of animals in a controlled experimental setting provide a valuable tool to advance understanding of genotype-phenotype relations, and to study the effects of genetic and environmental manipulations. To optimally benefit from the increasing numbers of genetically engineered mice, reliable high-throughput methods for comprehensive behavioral phenotyping of mice lines have become ...

Melatonin, a new addition to the armamentarium of anesthesiologist, has some unique properties that are highly desirable in routine peri-operative care. Available clinical data show that preoperative melatonin is as effective as benzodiazepines in reducing preoperative anxiety with minimal action on psychomotor performance and sleep wake cycle. It may be considered as a safe and effective alter...

CONTEXT The dental students experience a lot of stress, which increase when they perform their first surgical procedure. Yoga as an anxiolytic tool in anxiety reduction has been practiced over centuries in India. AIM To assess the efficacy of yoga in reducing the state trait anxiety of dental students before their first periodontal surgery performance. SETTINGS AND DESIGN A randomized contr...

Benzodiazepines should be prescribed on a short-term basis, but a significant proportion of patients (%) use them for more than 6 months, constituting a serious public health issue. Indeed, few strategies are effective in helping patients to discontinue long-term benzodiazepine treatments. The aim of this study was to assess the feasibility and the impact of a program including cognitive behavi...

A randomized controlled pilot study was carried out to determine the effect of a 15-minute practice of ANB exercise on experimentally induced anxiety using the simulated public speaking model in yoga-naïve healthy young adults. Thirty consenting medical students were equally divided into test and control groups. The test group performed alternate nostril breathing exercise for 15 minutes, while...

The pediatric emergency department can be frightening for children. Visits are unplanned, and frequently accompanied by significant emotional and physical distress. While treatment of pain and anxiety in children have been historically inadequate, the barriers to their treatment have largely been overcome through increased awareness, child- and family-focused care, standardized assessment, inst...

RATIONALE Evidence indicates that histamine (HA) modulates learning and memory in different types of behavioral tasks; however, the exact nature of this modulation and its mechanisms are controversial. Furthermore, emotions are able to influence memory processing in a crucial way through the involvement of the amygdala. Our research aims to contribute to the neurobiological body of knowledge on...

BACKGROUND Electromyography (EMG) is a useful test, but unfortunately also painful. We frequently encounter patients who worry about its painful nature, but tolerate it very well. OBJECTIVES We evaluated anxiety levels of patients referred for EMG to explore the possible correlating and contributing factors to high anxiety. METHODS A structured questionnaire, including the State-Trait Anxie...
