Exercising Self-Control Increases Responsivity to Hedonic and Eudaimonic Rewards.

The reward responsivity hypothesis of self-control proposes that, irrespective of self-control success, exercising self-control is aversive and engenders negative affect. To countermand this discomfort, reward-seeking behavior may be amplified after bouts of self-control, bringing individuals back to a mildly positive baseline state. Previous studies indicated that effort-an integral component of self-control-can increase reward responsivity.

Demystifying authenticity: Behavioral and neurophysiological signatures of self-positivity for authentic and presented selves.

Authenticity has captivated scholars. But what is it? An emerging view considers it exaggerated favorability (self-enhancement), whereas traditional views regard it as self-accuracy and self-consistency. We tested these theoretical views by contrasting the authentic self with the presented self, a highly desirable representation.

Authenticity, Well-Being, and Minority Stress in LGB Individuals: A Scoping Review.

In general (i.e. in heteronormative and cisgendered samples), authenticity appears protective against threats to well-being.

Liking Predicts Judgments of Authenticity in Real-Time Interactions More Robustly Than Personality States or Affect.

We conducted three studies involving small group interactions ( = 622) that examined whether Big Five personality states, affect, and/or liking predict judgments of others' authenticity. Study 1 ( = 119) revealed that neither -rated personality states nor affect predicted other-rated authenticity. Instead, other-rated liking was the only predictor of other-rated authenticity.

An Epidemiologic Comparison of Injuries to Skiers and Snowboarders Treated at United States Emergency Departments, 2000-2019.

Skiing and snowboarding are popular competitive and recreational sports that can be associated with significant injury. Previous studies of skiing and snowboarding injuries have been conducted, but studies evaluating injury types and patterns over long periods of time are needed to drive effective injury prevention efforts. We hypothesized that injury patterns would differ among snowboarders and skiers and that the number of injuries remained constant over time.

Test-retest reliability of spectral parameterization by 1/f characterization using SpecParam.

SpecParam (formally known as FOOOF) allows for the refined measurements of electroencephalography periodic and aperiodic activity, and potentially provides a non-invasive measurement of excitation: inhibition balance. However, little is known about the psychometric properties of this technique. This is integral for understanding the usefulness of SpecParam as a tool to determine differences in measurements of cognitive function, and electroencephalography activity.

Medication-invariant resting aperiodic and periodic neural activity in Parkinson's disease.

Parkinson's disease (PD) has been associated with greater total power in canonical frequency bands (i.e., alpha, beta) of the resting electroencephalogram (EEG).

The Role of Positive and Negative Aspects of Life Events in Depressive and Anxiety Symptoms.

Negative or stressful life events are robust risk factors for depression and anxiety. Less attention has been paid to positive aspects of events and whether positivity buffers the impact of negative aspects of events. The present study examined positivity and negativity of interpersonal and non-interpersonal episodic life events in predicting anxiety and depressive symptoms in a sample of 373 young adults.

Comparative bone histology of two thalattosaurians (Diapsida: Thalattosauria): from the Alpine Triassic (Middle Triassic) and a Thalattosauroidea indet. from the Carnian of Oregon (Late Triassic).

Here, we present the first bone histological and microanatomical study of thalattosaurians, an enigmatic group among Triassic marine reptiles. Two taxa of thalattosaurians, the askeptosauroid and one as yet undescribed thalattosauroid, are examined. Both taxa have a rather different microanatomy, tissue type, and growth pattern.

There is a party in my head and no one is invited: Resting-state electrocortical activity and solitude.

Objective: What are the motivational underpinnings of solitude? We know from self-report studies that increases in solitude are associated with drops in approach motivation and rises in avoidance motivation, but only when solitude is experienced as non-self-determined (i.e., non-autonomous).

Trait nostalgia: Four scales and a recommendation.

We review four established scales for measuring individual differences in trait-level nostalgia: the Nostalgia Inventory, the Southampton Nostalgia Scale, the Nostalgia Prototype Scale, and the Personal Inventory of Nostalgic Experiences. To examine their convergent validity, we re-analyzed data from a published study in which all four scales were administered simultaneously. Multi-group confirmatory factor analyses demonstrated that a one-factor model accurately described the interrelations among the four scales, and supported full metric and partial scalar invariance across U.

Assessment of NLRP3 Inflammasome Activation and NLRP3-NEK7 Complex Assembly.

The NLRP3 inflammasome is a critical component of innate immunity that activates caspase-1 to induce inflammation in response to a wide spectrum of endogenous and exogenous stimuli. NLRP3 inflammasome activation has been shown by assays for the cleavage of caspase-1 and gasdermin D, the maturation of IL-1β and IL-18, and ASC speck formation in innate immune cells such as macrophages and monocytes. Recently, NEK7 has been revealed as an essential regulator for NLRP3 inflammasome activation by forming high-molecular-weight complexes with NLRP3.

Acromioclavicular Joint Injuries in Sport.

Sport-related shoulder injuries, including disruptions to the acromioclavicular joint (ACJ), are common. An ACJ injury is classified by the degree and direction of the clavicle displacement. Although the diagnosis can be made clinically, standard radiographic views are important to determine the severity of the ACJ disruption and assess for concurrent injuries.

Bipolar spectrum disorders are associated with increased gray matter volume in the medial orbitofrontal cortex and nucleus accumbens.

Objective: Elevated sensitivity to rewards prospectively predicts Bipolar Spectrum Disorder (BSD) onset; however, it is unclear whether volumetric abnormalities also reflect BSD risk. BSDs emerge when critical neurodevelopment in frontal and striatal regions occurs in sex-specific ways. The current paper examined the volume of frontal and striatal brain regions in both individuals with and at risk for a BSD with exploratory analyses examining sex-specificity.

Grouping behavior in a Triassic marine apex predator.

Marine tetrapods occupy important roles in modern marine ecosystems and often gather in large aggregations driven by patchy prey distribution, social or reproductive behaviors, or oceanographic factors. Here, we show that similar grouping behaviors evolved in an early marine tetrapod lineage, documented by dozens of specimens of the giant ichthyosaur Shonisaurus in the Luning Formation in West Union Canyon, Nevada, USA. A concentration of at least seven skeletons closely preserved on a single bedding plane received the bulk of previous attention.

The leucine-rich repeat (LRR) domain of NLRP3 is required for NLRP3 inflammasome activation in macrophages.

The NLRP3 inflammasome is a critical component of innate immunity that defends the host from microbial infections. However, its aberrant activation contributes to the pathogenesis of several inflammatory diseases. Activation of the NLRP3 inflammasome induces the secretion of proinflammatory cytokines IL-1β and IL-18 and pyroptotic cell death.

How are successful matches made between homecare workers and older care receivers of different cultural backgrounds?

Understanding the process as well as the challenges and successes of matching homecare workers with older care receivers from differing cultural backgrounds may enhance practices that maximize quality-of-care outcomes and perceptions of quality of life for older adults, especially those "aging in place." Guided by a person-centered, consumer directed care model, this paper outlines the need for research that specifically aims to describe the matching process used by care coordinators when assigning homecare workers to older care receivers of different cultural backgrounds and how the needs and preferences of care receivers are balanced with the characteristics, skills, and capacities of the available pool of homecare workers.

Diagnosis of traumatic shoulder arthrotomies using saline load test with intra-articular pressure monitoring.

Purpose: The purpose of this study was to investigate the amount of saline required to identify a positive traumatic shoulder arthrotomy in a cadaveric model. In addition, intra-articular pressure monitoring was conducted to confirm needle placement and evaluate peak pressure curves prior to capsular failure.

Methods: We conducted a cadaveric study using thirty fresh-frozen upper extremities with maintained glenohumeral joint.

Posterior Shoulder Pain and Muscle Wasting in an Older Adult.

Musculoskeletal injuries are among the most common chief complaints in the geriatric population. Shoulder pain with associated deformity should be evaluated for possible joint dislocations, fractures, and musculotendinous tears. A comprehensive evaluation beginning with history and physical examination is important.

Pelvic ring injuries after road and mountain bike accidents.

Purpose: The purpose of this study was to compare patients with traumatic pelvic ring injuries sustained in road and mountain bicycling accidents to evaluate for differences in injury types and hospital courses.

Methods: A retrospective review of 60 patients presenting with pelvic ring injuries after road (n = 46) and mountain (n = 14) bicycling accidents was performed to compare patient/injury characteristics and hospital course.

Results: LC1 injuries were the most common pelvic ring injury (n = 31, 51.

Pelvic ring injuries after alpine ski and snowboard accidents.

Purpose: The purpose of this study was to analyze the patient/injury characteristics and associated hospital course of patients sustaining traumatic pelvic ring injuries after alpine ski and snowboard accidents at a level one trauma center in the Rocky Mountain region.

Methods: Patient/injury characteristics were obtained from patients presenting with pelvic ring injuries after alpine ski (n = 55) and snowboard (n = 9) accidents. Characteristics and outcomes analyzed included mechanism of injury, pelvic ring classification (Young-Burgess and Tile), hospital admission, physical therapy (PT) clearance, ambulation, length of stay, inpatient morphine milligram equivalents (MME), and discharges to rehabilitation facility.
