Abstract
Carpenter ants in the genus Camponotus are large, conspicuous ants that are abundant and ecologically influential in many terrestrial ecosystems. The bicolored carpenter ant, Camponotus ...vicinus Mayr, is distributed across a wide range of elevations and latitudes in western North America, where it is a prominent scavenger and predator. Here, we present a high-quality genome assembly of C. vicinus from a sample collected in Sonoma County, California, near the type locality of the species. This genome assembly consists of 38 scaffolds spanning 302.74 Mb, with contig N50 of 15.9 Mb, scaffold N50 of 19.9 Mb, and BUSCO completeness of 99.2%. This genome sequence will be a valuable resource for exploring the evolutionary ecology of C. vicinus and carpenter ants generally. It also provides an important tool for clarifying cryptic diversity within the C. vicinus species complex, a genetically diverse set of populations, some of which are quite localized and of conservation interest.
Objectives
Stress is highly prevalent in college students. Self-compassion, the tendency to respond in a caring manner to one’s own suffering or failures, reduces psychological distress and promotes ...mental health. Self-compassion may also influence physiological manifestations of stress; however, research is limited. Among undergraduate students over the course of an academic semester, we explored the associations of self-compassion with stress-related psychological variables including measures of affect, anxiety, and depressive symptoms. We also examined daily patterns of salivary cortisol over four days: diurnal slope, mean, and day-to-day cortisol rhythm stability.
Method
This sample of undergraduate students from introductory psychology courses in a large United States Midwestern university was predominantly non-Hispanic White (71.2%) and female (86.4%). All data were collected prior to final exams. After providing baseline psychosocial data, participants engaged in a 2-week mindfulness intervention: They were provided an iPod loaded with audio tracks based on the well-known Mindfulness-Based Stress Reduction intervention, but received no face-to-face instruction. Fifty-nine participants provided self-report demographic and medical data and completed the saliva sampling regimen over the first 4 days of the intervention. Diurnal salivary cortisol was assessed immediately after waking and again at bedtime over four consecutive days.
Results
Hierarchical multiple regressions replicated previous findings showing that self-compassion is associated with higher positive and lower negative affect, lower perceived stress, and fewer symptoms of anxiety and depression. Regression models controlling for oral contraception and tobacco use revealed a positive association of self-compassion with healthy cortisol profiles marked by steeper diurnal cortisol slopes and increased regularity of the inter-daily cortisol slope.
Conclusions
These results confirm that self-compassion may be protective against the psychological and physiological manifestations of stress in college. Kind and compassionate responses to one’s own struggles may shield students from the adverse effects of stress. The potential mechanisms underlying these associations are worthy of future research.

The circadian system temporally regulates physiology to maintain homeostasis. Co-opting and disrupting circadian signals appear to be distinct attributes that are functionally important for the ...development of a tumor and can enable or give rise to the hallmarks that tumors use to facilitate their initiation, growth and progression. Because circadian signals are also strong regulators of immune cell proliferation, trafficking and exhaustion states, they play a role in how tumors respond to immune-based cancer therapeutics. While immuno-oncology has heralded a paradigm shift in cancer therapeutics, greater accuracy is needed to increase our capability of predicting who will respond favorably to, or who is likely to experience the troubling adverse effects of, immunotherapy. Insights into circadian signals may further refine our understanding of biological determinants of response and help answer the fundamental question of whether certain perturbations in circadian signals interfere with the activity of immune checkpoint inhibitors. Here we review the body of literature highlighting circadian disruption as a cancer promoter and synthesize the burgeoning evidence suggesting circadian signals play a role in how tumors respond to immune-based anti-cancer therapeutics. The goal is to develop a framework to advance our understanding of the relationships between circadian markers, cancer biology, and immunotherapeutics. Bolstered by this new understanding, these relationships may then be pursued in future clinical studies to improve our ability to predict which patients will respond favorably to, and avoid the adverse effects of, traditional and immune-based cancer therapeutics.
Being a reviewer is an honor and it continues to be a very rewarding experience throughout a career. Reviewers get the opportunity to maintain scientific standards and assist in growing the ...scientific psychological literature. Being a reviewer enhances and integrates scientific values and clinical skills following the scientist-practitioner model. However, for the inexperienced reviewer, the experience can be very scary and intimidating. Everyone’s experience with reviewing is highly personal and at the same time, the activity is both common and universal for academic psychologists. In this interview article, three seasoned reviewers respond to questions about their experience as journal reviewers reflecting in their answers their collective wisdom and knowledge in this area.
Objectives
Patient experiences are critical when determining the acceptability of novel interventional pharmaceuticals. Here, we report the development and validation of a product acceptability ...questionnaire (SPRAY PAL) assessing feasibility, acceptability and tolerability of an intranasal Q-Griffithsin (Q-GRFT) drug product designed for COVID-19 prophylaxis.
Design
SPRAY PAL validation was undertaken as part of an ongoing phase 1 clinical trial designed to test the safety, pharmacokinetics and tolerability of intranasally administered Q-GRFT for the prevention of SARS-CoV-2 infection.
Setting
The phase 1 clinical trial took place at a University Outpatient Clinical Trials Unit from November 2021 to September 2023.
Participants
The initial SPRAY PAL questionnaire was piloted among healthy volunteers ages 25 to 55 in phase 1a of the clinical trial (N=18) and revised for administration in phase 1b for participants ages 24–59 (N=22).
Results
Spearman correlations tested convergent and discriminant validity. Internal consistency was assessed using Cronbach’s alpha, and test–retest reliability was assessed using intraclass correlation coefficients of responses collected from three repeated questionnaire administrations. The initial version demonstrated excellent internal consistency. The revised version demonstrated very good internal consistency after removal of one item (alpha=0.739). Excellent test–retest reliability (intraclass coefficient=0.927) and adequate convergent (r’s=0.208–0.774) and discriminant (r’s=0.123–0.392) validity were achieved. Subscales adequately distinguished between the constructs of acceptability, feasibility and tolerability.
Conclusions
The SPRAY PAL product acceptability questionnaire is a valid and reliable patient-reported outcomes measure that can be considered a credible tool for assessing patient-reported information about product acceptability, feasibility of use, tolerability of product and side effects and cost of product for novel intranasal drug formulations. The SPRAY PAL is generalisable, and items may be readily adapted to assess other intranasal formulations.

Circadian rest-Activity Rhythm Disorders (CARDs) are common in patients with cancer, particularly in advanced disease. CARDs are associated with increased symptom burden, poorer quality of life, and ...shorter survival. Research and reporting practices lack standardization, and formal diagnostic criteria do not exist. This electronic Delphi (e-Delphi) study aimed to formulate international recommendations for the assessment and diagnosis of CARDs in patients with cancer.
An international e-Delphi was performed using an online platform (Welphi). Round 1 developed statements regarding circadian rest-activity rhythms, diagnostic criteria, and assessment techniques. Rounds 2 and 3 involved participants rating their level of agreement with the statements and providing comments until consensus (defined internally as 67%) and stability between rounds were achieved. Recommendations were then created and distributed to participants for comments before being finalized.
Sixteen participants from nine different clinical specialties and seven different countries, with 5-35 years of relevant research experience, were recruited, and thirteen participants completed all three rounds. Of the 164 generated statements, 66% achieved consensus, and responses were stable between the final two rounds.
The e-Delphi resulted in international recommendations for assessing and diagnosing CARDs in patients with cancer. These recommendations should ensure standardized research and reporting practices in future studies.
