Background: To maintain standing balance, vestibular cues are processed and integrated with other sensorimotor signals to produce appropriate motor adjustments. Whole-body vestibular-driven postural responses are context-dependent and transformed based upon head and foot posture. Previous reports indicate the importance of intrinsic foot muscles during standing, but it is unclear how vestibular-driven responses of these muscles are modulated by alterations in stability and head posture.

Several methods can be used to mitigate coastal erosion, and one of the leading solutions is known as beach nourishment (BN), which involves using dredged material for nourishment, adding sand to extend an eroding beach. Although it has many advantages, the environmental impacts of BN remain poorly understood, especially on plastic pollution, which had not been investigated until this study. We aimed to compare the abundance and distribution of microplastics (MPs) found in intertidal sediments and specimens of the bivalve mollusks Crassostrea brasiliana, Mytella strigata, Perna perna, and Tivela mactroides, collected in two beaches of Vitoria, Southeast of Brazil (da Costa et al.

Naphthenic acids and naphthenic acid fraction compounds (NAFCs) are associated with production of unconventional petroleum resources, especially the Athabasca Oil Sands of Alberta, Canada. This complex mixture of acidic organic compounds is toxic to a variety of taxa, and so represents an important environmental management challenge. Thus, there is clear motivation to better understand the occurrence and characteristics of NAFCs in aquatic environments, their chemical behaviour, and environmental fate.

Management of stress and anxiety is often listed as the primary motivation behind cannabis use. Human research has found that chronic cannabis use is associated with increased basal cortisol levels but blunted neuroendocrine responses to stress. Preclinical research has demonstrated mixed effects of Δ-tetrahydrocannabinol (THC; the psychoactive constituent of cannabis), much of which is suggestive of dose-dependent effects; however, the predominance of this work has employed an injection method to deliver cannabis.

Background: Environmental and occupational health (EOH) assessments increasingly utilize systematic review methods and structured frameworks for evaluating evidence about the human health effects of exposures. However, there is no prevailing approach for how to integrate this evidence into decisions or recommendations. Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence-to-decision (EtD) frameworks provide a structure to support standardized and transparent consideration of relevant criteria to inform health decisions.

A soluble fraction of faba bean protein was conjugated with tannic acid via the free-radical grafting method using a mixture of ascorbic acid and hydrogen peroxide. Surface plasmon resonance showed a strong bonding between them, while the free amino and thiol group measurements indicated tannic acid's bonding with the amino groups and cysteine residues on the proteins. Structural analysis using intrinsic fluorescence and surface hydrophobicity demonstrated tannic acid's interaction with the aromatic and hydrophobic amino acids of the protein.

Background: Screen time is on the rise among youth, and as a result, cyberbullying victimization has become increasingly prevalent. While prior research has established a positive correlation between screen usage and cyberbullying victimization, a paucity of research has explored how motives for screen usage are associated with cyberbullying victimization and moderate the positive association between screen usage and cyberbullying victimization.
Objective: The present study sought to address these research gaps by exploring the association between motives for screen usage and cyberbullying victimization and examining whether these motives moderate the association between screen time and cyberbullying.

For some people the experience of visual imagery is lacking, a condition recently referred to as aphantasia. So far, most of the studies on aphantasia rely on subjective reports, leaving the question of whether mental images can exist without reaching consciousness unresolved. In the present study, the formation of mental images was estimated in individuals with aphantasia without explicitly asking them to generate mental images.

Delusions are a defining feature of psychosis and play an important role in the conceptualization and diagnosis of psychotic disorders; however, the particular role that different delusions play in the prognosis of these disorders is not well understood. This study explored relationships between delusions and other symptoms in 674 first episode psychosis (FEP) individuals by comparing symptom networks between baseline and 12 months after intake to an early intervention service. Specifically, we (1) estimated regularized partial correlation networks at baseline and month 12, (2) identified the most central symptoms in each network, (3) identified clusters of highly connected symptoms, and (4) compared networks to examine changes in structure and connectivity.

Executive functions can be classified into processes of inhibition, working memory and shifting, which together support flexible and goal-directed behaviour and are crucial for both current and later-life outcomes. A large body of literature has identified distinct brain regions critical to performing each of these functions. These findings are however predicated on a piecemeal and single-task approach.

Smith+Nephew, Watford, Hertfordshire, UK.
Background: Achievement of moisture balance can be a critical factor affecting time to closure of nonhealing wounds, and dry wounds can take much longer to heal than those with high exudate levels. Whether the goal of management is to donate moisture to the wound or control excessive fluid until the cause has been identified and addressed, choice of dressing and other wound management products can affect nursing resources, clinical outcomes, concordance, and quality of life for the patient.
Case Reports: The cases discussed illustrate differences in management approaches for dry and wet wounds and show how clinician support tools (eg, tissue type, infection/inflammation, moisture imbalance, epithelial edge advancement [TIME] clinical decision support tool) can facilitate treatment decisions.
