BACKGROUND: Universities' responsibility to ensure academic integrity is frustrated by software and communication tools that facilitate content reuse coupled with a growing international essay writing economy. A wide range of behaviours constitute academic dishonesty and while a complex phenomenon to examine, existing evidence suggests that there is sufficient proliferation (both in volume and variety) of these behaviours among Australian university students to warrant concern. This proliferation presents faculty and staff with new challenges in ensuring academic integrity...

This document represents the official position of the American Association of Clinical Endocrinologists and American College of Endocrinology. Where there are no randomized controlled trials or specific U.S. FDA labeling for issues in clinical practice, the participating clinical experts utilized their judgment and experience. Every effort was made to achieve consensus among the committee members. Position statements are meant to provide guidance, but they are not to be considered prescriptive for any individual patient and cannot replace the judgment of a clinician...

The Society of Behavioral Medicine recommends school officials start middle and high school classes at 8:30 am or later. Such a schedule promotes students' sleep health, resulting in improvements in physical health, psychological well-being, attention and concentration, academic performance, and driving safety. In this position statement, we propose a four-tiered approach to promote later school start times for middle and high schools.

Genome editing of human embryos could become a fundamental treatment approach for genetic diseases; however, a few technical and ethical issues need to be resolved before its application in clinical settings. Presently, the Japanese government has issued a statement prohibiting human germline editing and emphasizing the need for discussions that include a wide range of perspectives. However, current discussions tend to exclude the general public. Therefore, we conducted a survey of 10,881 general adults and 1044 patients in Japan who indicated that their disease conditions are related to their genetic makeup, and clarified their attitude toward this technology...

BACKGROUND: Delirium occurs frequently in intensive care unit (ICU) patients and is associated with numerous deleterious outcomes. There is a large variation in reported delirium occurrence rates, ranging from 4% to 89%. Apart from patient and treatment-related factors, organisational factors could influence delirium incidence, but this is currently unknown. OBJECTIVE: To systematically review delirium incidence and determine whether or not organisational factors may contribute to the observed delirium incidence in adult ICU patients...

BACKGROUND: Stroke treatment is a continuum that begins with the rapid identification of symptoms and treatment with transition to successful rehabilitation. Therapies for acute ischemic stroke (AIS) may vary based on anatomic location, interval from symptom onset, and coexisting health conditions. Successful therapy requires a seamless systematic approach with coordination from prehospital environment through acute management at medical facilities to disposition and long-term care of the patient...

BACKGROUND: In medical practice, long term interventions are common and they require timely planning of the involved processes. Unfortunately, evidence-based statements about time are hard to find in Clinical Practice Guidelines (CPGs) and in other sources of medical knowledge. At the same time, health care centers use medical records and information systems to register data about clinical processes and patients, including time information about the encounters, prescriptions, and other clinical actions...

BACKGROUND: DNA methylation (global and gene-specific) has been reported as an epigenetic mechanism that could be involved in the pathogenesis of type 2 diabetes mellitus (T2DM). Furthermore, epigenetic therapy has been suggested as a future possibility for T2DM treatment. Epigenetic changes illustrate the environmental link of the disease. Since some of the epigenetic modifications can be reversed, they could be used as potential therapeutic targets. The aim of the systematic review will be to synthesise the available evidence pertaining to the link between DNA methylation and T2DM...

Importance: The 1996 Tonsillectomy and Adenoidectomy Inpatient Guidelines of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) Pediatric Otolaryngology Committee recommended that children younger than 3 years be admitted following tonsillectomy. Recommendations for hospital observation were not included as a key action statement in the 2011 AAO-HNS Clinical Practice Guidelines for Tonsillectomy in Children. Objective: To examine the association between posttonsillectomy complication rate and the age and weight of the child at the time of surgery...

Microdeletion of a region in chromosome 16p11.2 increases susceptibility to autism. Although this region contains exons of 29 genes, disrupting only a small segment of the region, which spans 5 genes, is sufficient to cause autistic traits. One candidate gene in this critical segment is MVP , which encodes for the major vault protein (MVP) that has been implicated in regulation of cellular transport mechanisms. MVP expression levels in MVP +/- mice closely phenocopy those of 16p11.2 mutant mice, suggesting that MVP +/- mice may serve as a model of MVP function in 16p11...

Hyperacetylation of tau has been implicated in neurodegeneration and cognitive decline in tauopathy brains. The NAD-dependent class III protein deacetylase SIRT1 is one of major enzymes involved in removal of acetyl groups from tau in vitro However, whether SIRT1 regulates acetylation of pathogenic tau and ameliorates tau-mediated pathogenesis remains unclear. Here, we report deacetylating activity of SIRT1 for acetylated Lys174 (K174) of tau in tauP301S transgenic mice with a brain-specific SIRT1 deletion...

The c-Jun N-terminal kinase (JNK) signal transduction pathway is implicated in learning and memory. Here, we examined the role of JNK activation mediated by the JIP1 scaffold protein. We compared male wild-type mice with a mouse model harboring a point mutation in the Jip1 gene that selectively blocks JIP1-mediated JNK activation. These male mutant mice exhibited increased NMDA receptor currents, increased NMDA receptor-mediated gene expression, and a lower threshold for induction of hippocampal long-term potentiation...

Insect auditory receivers provide an excellent comparative resource to understand general principles of auditory transduction, but analysis of the electrophysiological properties of the auditory neurons has been hampered by their tiny size and inaccessibility. Here we pioneer patch-clamp recordings from the auditory neurons of Müller-s Organ of the desert locust Schistocerca gregaria to characterise dendritic spikes, axonal spikes and the transduction current. We demonstrate that dendritic spikes, elicited by sound stimuli, trigger axonal spikes, and that both types are sodium- and voltage-dependent and blocked by TTX...

Neurophysiological data obtained in primates suggests that merely observing others' actions can modulate activity in the observer's motor cortices. In humans, it has been suggested that these multimodal vicarious responses extend well beyond the motor cortices, including somatosensory and insular brain regions, that seem to yield vicarious responses when witnessing others' actions, sensations or emotions (Gazzola and Keysers, 2009). Despite the wealth of data with respect to shared action responses in the monkey motor system, whether the somatosensory and insular cortices also yield vicarious responses during observation of touch remains largely unknown...

The presence of contralateral tactile input can profoundly affect ipsilateral tactile perception and unilateral stroke in somatosensory areas can result in bilateral tactile deficits, suggesting that bilateral tactile integration is an important part of brain function. Whereas previous studies have shown that bilateral tactile inputs exist and that there are neural interactions between inputs from the two sides, no previous study explored to what extent the local neuronal circuitry processing contains detailed information about the nature of the tactile input from the two sides...

Itch is an unpleasant sensation that initiates scratching behavior. Itch-scratch reaction is a complex phenomenon whose occurrence implicates supraspinal structures required for regulation of sensory, emotional, cognitive, and motivational aspects. However, the central mechanisms underlying the processing of itch and the interplay of the supraspinal regions and spinal cord in regulating itch-scratch processes are poorly understood. Here, we have identified that the neural projections from anterior cingulate cortex (ACC) to dorsal medial striatum (DMS) constitute a critical circuit element for regulating itch-related behaviors in the brain of male C57BL/6J mice...

Kainate receptors are members of the glutamate receptor family that function both by generating ionotropic currents through an integral ion channel pore, and through coupling to downstream metabotropic signaling pathways. They are highly expressed in the striatum yet their roles in regulating striatal synapses are not known. Using mice of both sexes we demonstrate that GluK2 containing kainate receptors expressed in direct pathway Spiny Projection Neurons (dSPNs) inhibit glutamate release at corticostriatal synapses in the dorsolateral striatum...
