The analyses were performed using the specific programs embedded in Proteome Discoverer, Scaffold, and an in-house algorithm (BuildSummary). find more These results provide valuable guidelines for the optimal interpretation of proteomic results and the development of fit-for-purpose protocols under different situations.The functions of soft robotics are intimately tied to their form-channels and voids defined by an elastomeric superstructure that reversibly stores and releases mechanical energy to change shape, grip objects, and achieve complex motions. Here, we demonstrate that covalent polymer mechanochemistry provides a viable mechanism to convert the same mechanical potential energy used for actuation in soft robots into a mechanochromic, covalent chemical response. A bis-alkene functionalized spiropyran (SP) mechanophore is cured into a molded poly(dimethylsiloxane) (PDMS) soft robot walker and gripper. The stresses and strains necessary for SP activation are compatible with soft robot function. The color change associated with actuation suggests opportunities for not only new color changing or camouflaging strategies, but also the possibility for simultaneous activation of latent chemistry (e.g., release of small molecules, change in mechanical properties, activation of catalysts, etc.) in soft robots. In addition, mechanochromic stress mapping in a functional robotic device might provide a useful design and optimization tool, revealing spatial and temporal force evolution within the robot in a way that might be coupled to autonomous feedback loops that allow the robot to regulate its own activity. The demonstration motivates the simultaneous development of new combinations of mechanophores, materials, and soft, active devices for enhanced functionality.There are many reported examples of small structural modifications to GPCR-targeted ligands leading to major changes in their functional activity, converting agonists into antagonists or vice versa. These shifts in functional activity are often accompanied by negligible changes in binding affinity. The current perspective focuses on outlining and analyzing various approaches that have been used to interconvert GPCR agonists, partial agonists, and antagonists in order to achieve the intended functional activity at a GPCR of therapeutic interest. An improved understanding of specific structural modifications that are likely to alter the functional activity of a GPCR ligand may be of use to researchers designing GPCR-targeted drugs and/or probe compounds, specifically in cases where a particular ligand exhibits good potency but not the preferred functional activity at the GPCR of choice.
Right atrial myxoma accounts for 15-20% of cardiac myxomas and syncope is a very rare manifestation. We present the case of an 89-year-old man with right atrial myxoma and syncope, and discuss the role of cardiac magnetic resonance imaging (MRI) in the diagnosis of myxomas.

An 89-year-old man with a history of hypertension, hyperlipidemia, chronic kidney disease stage 4, mild dementia, and benign prostatic hyperplasia presented to the emergency department with an episode of syncope. Physical examination demonstrated normal and regular heart sounds, and normal respiratory rate and oxygen saturation. Echocardiogram described a well-circumscribed echo-dense mass in the right atrial cavity, which was attached to the septum but not obstructing the tricuspid annulus, measuring 1.7×2.2 cm at its widest diameter. Cardiac MRI revealed a mass with dark intensity which enhanced heterogeneously following intravenous administration of gadolinium-chelate, consistent with a myxoma. The location of this myxoma, coupled with the presence of a stalk allowing mobility, provides a clue to how this patient experienced transient obstruction of the tricuspid valve leading to syncope.

Right heart tumors should be considered in the differential diagnosis of unexplained syncope. Cardiac MRI with gadolinium-chelate administration can help differentiate this tumor from a right-sided atrial thrombus, which can pose a diagnostic challenge.

To investigate the effects of an uphill marathon (43 km, 3063-m elevation gain) on running mechanics and neuromuscular fatigue in lower-limb muscles.

Maximal mechanical power of lower limbs (MMP), temporal tensiomyographic (TMG) parameters, and muscle-belly displacement (Dm) were determined in the vastus lateralis muscle before and after the competition in 18 runners (age 42.8 ± 9.9 y, body mass 70.1 ± 7.3 kg, maximal oxygen uptake 55.5 ± 7.5 mL · kg-1 · min-1). Contact (tc) and aerial (ta) times, step frequency (f), and running velocity (v) were measured at 3, 14, and 30 km and after the finish line (POST). Peak vertical ground-reaction force (Fmax), vertical displacement of the center of mass (Δz), leg-length change (ΔL), and vertical (kvert) and leg (kleg) stiffness were calculated.

MMP was inversely related with race time (r = -.56, P = .016), tc (r = -.61, P = .008), and Δz (r = -.57, P = .012) and directly related with Fmax (r = .59, P = .010), ta (r = .48, P = .040), and kvert (r = .51, P = .027)marathons.
Expressive writing has been shown to improve quality of life, fatigue, and posttraumatic stress among breast cancer patients across cultures. Understanding how and why the method may be beneficial to patients can increase awareness of the psychosocial impact of breast cancer and enhance interventional work within this population. Qualitative research on experiential aspects of interventions may inform the theoretical understanding and generate hypotheses for future studies.

The aim of the study was to explore and describe the experience and feasibility of expressive writing among women with breast cancer following mastectomy and immediate or delayed reconstructive surgery.

Seven participants enrolled to undertake 4 episodes of expressive writing at home, with semistructured interviews conducted afterward and analyzed using experiential thematic analysis.

Three themes emerged through analysis writing as process, writing as therapeutic, and writing as a means to help others.

Findings illuminate experiential variations in expressive writing and how storytelling encourages a release of cognitive and emotional strains, surrendering these to reside in the text. The method was said to process feelings and capture experiences tied to a new and overwhelming illness situation, as impressions became expressions through writing. Expressive writing, therefore, is a valuable tool for healthcare providers to introduce into the plan of care for patients with breast cancer and potentially other cancer patient groups.

This study augments existing evidence to support the appropriateness of expressive writing as an intervention after a breast cancer diagnosis. Further studies should evaluate its feasibility at different time points in survivorship.

Current management for a symptom cluster of pain, fatigue, and disturbed sleep in breast cancer patients has limited effects.

The purposes of this prospective, randomized controlled pilot study were to (1) assess the feasibility and tolerability of auricular point acupressure (APA) intervention to manage pain, fatigue, and sleep disturbance in breast cancer patients and (2) provide an initial appraisal of effect size as compared with a control intervention.

Thirty-one participants were randomized into either an active APA group (n = 16) or a control APA group (n = 15), which included the sham APA treatment not related to the symptoms. link2 All participants received the APA once a week for 4 weeks. Self-report measures were obtained at baseline, weekly during intervention, at end of intervention, and at a 1-month follow-up.

For the 4-week of APA treatment, the retention rate was 88% for the active APA group and 73% for the control APA group. After 4 weeks of APA, participants in the active APA treatment had reported a reduction of 71% in pain, 44% in fatigue, 31% in sleep disturbance, and 61% in interference with daily activities. The control APA group experienced some moderate reduction in these symptoms.

Given that this was a pilot study with a small sample size, results must be interpreted with caution.

Our results suggest that APA may provide an inexpensive and effective complementary approach for the management of symptom clusters for breast cancer patients, and further study is warranted.

Little is known about the influence of cancer on the adolescent's developing self-identity and social relationships as he/she transitions back to school following cancer treatment.

The purpose of this study was to explore the meaning of returning to school for adolescents who have completed cancer treatment.

In this qualitative study, in-depth interviews using an interpretive descriptive approach were conducted with 11 adolescents (aged 13-17 years) who had completed treatment for cancer. The transcripts of the audiotaped interviews were analyzed thematically and reviewed by the study team.

Three main themes suggested that the return to school hallmarked the end of an illness episode and a welcome return to a sense of well-being (a) being on the right track, (b) bridging two worlds, and (c) establishing a new life at school. Nearly all adolescents described being negatively impacted by the cancer experience. However, the ability to maintain friendships during the transition emerged as particularly salient to allow the adolescents to rise above the challenges and residual effects of cancer treatment.

Returning to school following cancer treatment affects adolescents' beliefs about themselves, their self-identity, and their social relationships. Understanding the meaning that adolescents ascribed to returning to school facilitated the development of practice recommendations to improve adjustment to school.

Our study findings illuminate an important gap in the existing resources for adolescents in the posttreatment phase of cancer. Recommendations to promote healthy psychosocial development are proposed to better support adolescents during the reintegration to school.
