General anesthesia in patients with or at risk for neuronal injury remains challenging due to the neurotoxic effects of volatile anesthetics. One inhalation anesthetic, sevoflurane, induces neuronal damage, including neuroapoptosis, and learning and memory impairment. Panax Notoginseng Saponins (PNS) is the active ingredient of Sanqui and has been reported to exert neuroprotective effects. In the current study, the protective effect of PNS on sevoflurane‑induced nerve cell injury was explored. Cell proliferation was significantly reduced in a dose‑dependent manner following stimulation with sevoflurane...

BACKGROUND: The first step in identifying risk factors for injuries is to characterize the myoelectric activity of different muscles after ground contact, especially when fatigue is a limiting factor. This study aimed at: (a) recording the myoelectric activity of calf muscles after ground contact during different types of jumps and (b) investigating the effect of motor learning and fatigue on muscle pre-activation. METHODS: Twenty four male students aged 24.3 ± 1...

Active learning strategies have proved effective in changing behaviours and encouraging continuing professional development (CPD) in nursing. Narrative pedagogy in particular has demonstrated its usefulness in this regard. This article describes narrative pedagogy through the lens of learning activities conducted in the classroom and in the course of practicum and CPD experiences. It also examines the challenges associated with implementing such activities and how to meet them. This includes not determining the content of activities completely in advance, specifying that the content to be discussed is not entirely known, that additional research could be required and that different options are to be explored, allowing students to express themselves freely, and tolerating moments of silence...

Treatment for Angelman syndrome (AS) is currently limited to symptomatic interventions. A mouse model of AS has reduced calcium/calmodulin-dependent kinase II activity due to excessive phosphorylation of specific threonine residues, leading to diminished long-term potentiation. In a rat model of Parkinson disease, levodopa reduced phosphorylation of various proteins, including calcium/calmodulin-dependent kinase II. Further studies demonstrated that AS mice treated with levodopa performed better on rotarod testing than untreated AS mice...

Mobile technology is increasingly being used to measure individuals' moods, thoughts, and behaviors in real time. Current examples include the use of smartphones to collect ecological momentary assessments (EMAs; assessments delivered "in the moment"); wearable technology to passively collect objective measures of participants' movement, physical activity, sleep, and physiological response; and smartphones and wearable devices with global positioning system (GPS) capabilities to collect precise information about where participants spend their time...

Community-based participatory researchers increasingly incorporate photography and social media into their work. Despite its relative infancy, social media has created a powerful network that allows individuals to convey messages quickly to a widespread audience. In addition to its potential benefits, the use of social media in research also carries risk, given the fast pace of exchanges, sharing of personal images and ideas in high accessibility, low privacy contexts and continually shifting options and upgrades...

BACKGROUND: While translational genomic sequencing research is increasing, few studies have been limited to healthy individuals; most have focused on patients with a disease or a strong family history of a disorder. The limited studies that have included healthy individuals have focused on the disclosure of medically actionable secondary results, rather than carrier status, to assess reproductive risks. To address this important gap, we conducted the NextGen study, which focuses on carrier status and medically actionable secondary findings in a population of women planning a pregnancy...

BACKGROUND: The N-methyl-D-aspartate (NMDA) receptors are glutamate receptors that play vital roles in central nervous system development and are involved in synaptic plasticity, which is an essential process for learning and memory. The subunit N-methyl D-aspartate receptor subtype 2B (NR2B) is the chief excitatory neurotransmitter receptor in the mammalian brain. Disturbances in the neurotransmission mediated by the NMDA receptor are caused by its overexposure to glutamate neurotransmitter and can be treated by its binding to an antagonist...

The current experiment investigated generalizability of motor learning in proximal versus distal effectors in upper extremities. Twenty-eight participants were divided into three groups: training proximal effectors, training distal effectors, and no training control group (CG). Performance was tested pre- and post-training for specific learning and three learning transfer conditions: (1) bilateral learning transfer between homologous effectors, (2) lateral learning transfer between non-homologous effectors, and (3) bilateral learning transfer between non-homologous effectors...

The recent passage of state youth sports concussion laws across the country introduces clinical implications for health care professionals caring for student-athletes. Although the laws were established to provide protections for student-athletes and prevent adverse outcomes, efforts aimed at implementation have uncovered various challenges in concussion diagnosis and management. Some of the most salient issues include medical evaluation, return to play, and return to learn. For this reason, health care professionals play a pivotal role in determining the critical next steps after a student is removed from play with a suspected concussion...

Event discovery aims to discover a temporal segment of interest, such as human behavior, actions or activities. Most approaches to event discovery within or between time series use supervised learning. This becomes problematic when some relevant event labels are unknown, are difficult to detect, or not all possible combinations of events have been anticipated. To overcome these problems, this paper explores Common Event Discovery (CED), a new problem that aims to discover common events of variable-length segments in an unsupervised manner...

Dendritic spines are actin-rich, postsynaptic protrusions that contact presynaptic terminals to form excitatory chemical synapses. These synaptic contacts are widely believed to be the sites of memory formation and information storage, and changes in spine shape are thought to underlie several forms of learning-related plasticity. Both membrane trafficking pathways and the actin cytoskeleton drive activity-dependent structural and functional changes in dendritic spines. A key molecular player in regulating these processes is the activity-regulated cytoskeleton-associated protein (Arc), a protein that has diverse roles in expression of synaptic plasticity...

This article contributes to the understanding of embodied practices and experiences within adapted physical activity. It presents a study of a 4-day winter sports camp for young people with cerebral palsy. The experiences of the participants were investigated through qualitative interviews. The findings are analyzed through a phenomenological framework of embodiment and the notions of body schema and body image. By paying special attention to the bodily experience of "I can," this study shows that participants learned new ways of approaching challenges, gained bodily control in challenging situations, expanded their fields of possible actions through practicing, as well as learned to understand and accept themselves...

Research from cognitive science and geoscience education has shown that sketching can improve spatial thinking skills and facilitate solving spatially complex problems. Yet sketching is rarely implemented in introductory geosciences courses, due to time needed to grade sketches and lack of materials that incorporate cognitive science research. Here, we report a design-centered, collaborative effort, between geoscientists, cognitive scientists, and artificial intelligence (AI) researchers, to characterize spatial learning challenges in geoscience and to design sketch activities that use a sketch-understanding program, CogSketch...

Repeated cycles of alcohol [ethanol (EtOH)] intoxication and withdrawal dysregulate excitatory glutamatergic systems in the brain and induce neuroadaptations in the medial prefrontal cortex (mPFC) that contribute to cognitive dysfunction. The mPFC is composed of subdivisions that are functionally distinct, with dorsal regions facilitating drug-cue associations and ventral regions modulating new learning in the absence of drug. A key modulator of glutamatergic activity is the holoenzyme calcium/calmodulin-dependent protein kinase II (CaMKII) that phosphorylates ionotropic glutamate receptors...

There is a rapidly growing group of aging adults with autism spectrum disorder (ASD) who may have unique needs, yet cognitive and brain function in older adults with ASD is understudied. We combined functional and structural neuroimaging and neuropsychological tests to examine differences between middle-aged men with ASD and matched neurotypical (NT) men. Participants (ASD, n = 16; NT, n = 17) aged 40-64 years were well-matched according to age, IQ (range: 83-131), and education (range: 9-20 years)...

Given the pivotal roles that CD4 T cell imbalance plays in human immune disorders, much interest centres on better understanding influences that regulate human helper T cell subset dominance in vivo. Here, using primary CD4 T cells and short-term Th1 and Th2-like lines, we investigated roles and mechanisms by which neurotransmitter receptors may influence human Type 1 vs Type 2 immunity. We hypothesized N-methyl-D-aspartate receptors (NMDA-R), which play key roles in memory and learning, can also regulate human CD4+ T cell function through induction of excitotoxicity...

Liquiritigenin (LQ), a flavonoid extracted from the radix of Glycyrrhiza, has anti-inflammatory and neuroprotective properties. In this study, we evaluated the cognitive enhancing effects of LQ on learning and memory impairments induced by scopolamine (0.5 mg/kg, i.p.), a muscarinic antagonist, using the Y-maze, passive avoidance, and novel object recognition tests. A single administration of LQ significantly improved scopolamine-induced cognitive impairments in these behavioral tests. In addition, LQ dramatically inhibited acetylcholinesterase and thiobarbituric acid reactive substance activities in the hippocampus of scopolamine-induced mice in a dose-dependent manner...

Daytime napping offers various benefits for healthy adults, including enhancement of motor skill learning. It remains controversial whether napping can provide the same enhancement as overnight sleep, and if so, whether the same neural underpinning is recruited. To investigate this issue, we conducted functional MRI during motor skill learning, before and after a short day-nap, in 13 participants, and compared them with a larger group (N=47) who were tested following regular overnight sleep. Training in a sequential finger-tapping task required participants to press a keyboard in the MRI scanner with their non-dominant left hand as quickly and accurately as possible...
