Challenges and Research Opportunities for Integrating Quantitative Electroencephalography Into Sports Concussion Rehabilitation.

Although concussion management and return to play/learn decision making focuses on reducing symptoms, there is growing interest in objective physiological approaches to treatment. Clinical and technological advancements have aided concussion management; however, the scientific study of the neurophysiology of concussion has not translated into its standard of care. This expert commentary is motivated by novel clinical applications of electroencephalographic-based neurofeedback approaches (eg, quantitative electroencephalography [QEEG]) for treating traumatic brain injury and emerging research interest in its translation for treating concussion.

Progerin can induce DNA damage in the absence of global changes in replication or cell proliferation.

Hutchinson-Gilford Progeria Syndrome (HGPS) is a rare genetic condition characterized by features of accelerated aging, and individuals with HGPS seldom live beyond their mid-teens. The syndrome is commonly caused by a point mutation in the LMNA gene which codes for lamin A and its splice variant lamin C, components of the nuclear lamina. The mutation causing HGPS leads to production of a truncated, farnesylated form of lamin A referred to as "progerin.

Post-concussion changes in the N200 and P300 ERPs are associated with cognitive symptoms and performance.

Purpose: To examine how post-concussion changes to the N200 and P300 event-related potentials (ERPs) are associated with cognitive symptoms and neurocognitive performance.

Methods: High-density electroencephalography (EEG) was recorded during a Go/No-Go task from 16 young adults within one month after their concussion and 16 matched controls. Participants were also administered the Cognitive-Linguistic Quick Test (CLQT) and self-reported concussion-like symptoms.

Designing high-performance asymmetric and hybrid energy devices via merging supercapacitive/pseudopcapacitive and Li-ion battery type electrodes.

We report a strategic development of asymmetric (supercapacitive-pseudocapacitive) and hybrid (supercapacitive/pseudocapacitive-battery) energy device architectures as generation-II electrochemical energy systems. We derived performance-potential estimation regarding the specific power, specific energy, and fast charge-discharge cyclic capability. Among the conceived group, pseudocapacitor-battery hybrid device is constructed with a high-rate intrinsic asymmetric pseudocapacitive (α - MnO/rGO) and a high-capacity Li-ion intercalation battery type (po-nSi/rGO) electrodes.

Aging and the visual perception of rigid and nonrigid motion.

Nonrigid forms of motion are commonplace in everyday life. Given previously documented age-related deteriorations in various tasks involving motion (discriminating speed, identifying motion direction, etc.), an experiment was conducted to evaluate the potential effect of age upon the visual ability to detect rigid and nonrigid object motion.

Calcium alginate-biochar composite immobilized A. ferrooxidans effectively removes sulfate and ferric iron from acid mine drainage.

Bioremediation has been applied in the treatment of acid mine drainage (AMD), but high levels of sulfate (SO) and ferric iron (Fe) in AMD often affect microbial activity. A novel biochar-microorganism composite (I-CMR600) was developed by alginate gel-embedding method to improve the tolerance of microorganisms and the removal effects of SO and Fe in AMD, and its removal mechanism and biological behavior were explored in this study. The removal performance of I-CMR600 under different influencing factors was studied by batch adsorption experiments.

The Effect of Sampling Context on Preschoolers' Finite Verb Morphology Composite Scores.

Purpose: The finite verb morphology composite (FVMC) is a valid measure for charting children's tense development and for differentiating children with and without language impairment during preschool and early elementary years. However, it is unclear whether FVMC scores vary as a function of language sample elicitation contexts. The current study evaluated the performance on FVMC in preschool-aged children across different language sampling contexts.

Lameness of horses is effectively ameliorated with a low volume of mepivacaine administered as a palmar digital nerve block.

Objective: To determine the effect of 1.5 mL 2% mepivacaine, 0.75 mL 2% mepivacaine, and a combination of 0.

The Effects of the Great Depression on Children's Intergenerational Mobility.

This article examines the role of the Great Depression in shaping the intergenerational mobility of some of the most upwardly mobile cohorts of the twentieth century. Using newly linked census and vital records from the Longitudinal, Intergenerational Family Electronic Micro-database, we examine the occupational and educational mobility of more than 265,000 sons and daughters born in Ohio and North Carolina. We find that the deepest and most protracted downturn in U.

Fifty-four subjects aged 20-27 years (Mean age 23.07, SD ± 1.

Thinking outside the red box: Does the simultaneous Showup distinguish between filler siphoning and diagnostic feature detection accounts of lineup/Showup differences?

Lineups are considered a superior method of identification to showups, but why is contested. There are two main theories: diagnostic feature detection theory, which holds that surrounding the suspect with fillers causes the eyewitness to focus on the features that are most diagnostic, and differential filler siphoning theory that claims that the fillers draw incorrect choices away from the suspect. Colloff and Wixted (2020) created a novel identification task, called a simultaneous showup, designed to prevent filler siphoning, while still allowing comparison to occur between members of the array.

Effect of melatonin supplementation upon parental care and nestling growth in arctic-breeding songbirds.

Arctic-breeding birds exhibit around-the-clock activity, and these activity cycles are postulated to maximize reproductive success during the short breeding season characteristic of high-latitude regions. Two closely related species of arctic-breeding songbirds, Lapland longspurs (Calcarius lapponicus; ground-nesting) and snow buntings (Plectrophenax nivalis; cavity-nesting) exhibit extended activity cycles throughout the polar day (71° N) except for 4-5 h of daily quiescence. Ground-nesting Lapland longspurs experience higher levels of nest predation than cavity-nesting snow buntings, and this difference is reflected in elevated nest vigilance in male longspurs compared with snow buntings.

Attuned to the Flux of Life: Relations Between Ability Emotional Intelligence and Emotional Reactivity.

The field of ability-related emotional intelligence (ability EI) could benefit from new perspectives concerning dynamic operations. According to a recent perspective, variations in ability EI are likely to be linked to variations in skills related to evaluation. This perspective contends, perhaps counterintuitively, that higher levels of ability EI are likely to be linked to higher levels of emotional reactivity, defined in terms of stronger event-emotion relationships.

Time budgets differ in horses during continuous and space-restricted rotational grazing.

Horses can become obese and develop related health issues such as laminitis from excessive grazing on high-quality pasture grass; limiting pasture intake can allow weight loss to occur. The objective of this study was to determine the effect of space-restricted rotational grazing on body weight (BW) and time budgets in horses. Eight mature geldings and mares with maintenance-only requirements were randomly assigned to either a space-restricted rotational grazing group (SRG; BW 512 ± 6 kg; = 4) or a continuous grazing group (CG; BW 517 ± 49 kg; = 4) for 42 d SRG horses grazed an area with dimensions to provide 80-90 % of mean digestible energy requirement for the 4 horses over a 7-d grazing period; whereas, the CG horses continuously grazed similar non-toxic endophyte-infected tall fescue pasture providing greater than maintenance requirements for the 42 d Horses in the SRG group were moved to a new area every 7 d for 6 weeks.

Effect of glucocorticoid blockade on inflammatory responses to acute sleep fragmentation in male mice.

The association between sleep and the immune-endocrine system is well recognized, but the nature of that relationship is not well understood. Sleep fragmentation induces a pro-inflammatory response in peripheral tissues and brain, but it also activates the hypothalamic-pituitary-adrenal (HPA) axis, releasing glucocorticoids (GCs) (cortisol in humans and corticosterone in mice). It is unclear whether this rapid release of glucocorticoids acts to potentiate or dampen the inflammatory response in the short term.

Benefits of Resistance Training During Pregnancy for Maternal and Fetal Health: A Brief Overview.

Research demonstrates resistance training is not only safe but also beneficial for pregnant women. However, exercise recommendations for pregnant women still minimize the importance of resistance exercise and provide minimal guidance. With a large increase in strength-focused sports among women, it is critical to re-evaluate the risk/benefit ratio of these exercises and ensure the latest recommendations reflect the latest clinical research.
