A new correlative light electron microscopy method shows plasmodesmata ultrastructure in the graft interface.
Reindeer (Rangifer tarandus) have shaped the cultures and provided livelihood to peoples of the Northern Hemisphere for thousands of years. They are still the socio-economic cornerstone of many northern cultures. Insight into reindeer mortality patterns is important for understanding past human-reindeer interactions and reindeer population fluctuations in relation to climatic and environmental change. Beyond archaeology, assessing the age structures of modern reindeer populations is important for developing wildlife management strategies. This paper presents a quick, non-destructive and cheap method to estimate age in reindeer in both modern and ancient populations based on tooth wear and eruption patterns of mandibular teeth. We devised the method using a large sample of Svalbard reindeer (Rangifer tarandus platyrhynchus) of known age. We blind-tested the method and tested its applicability on another known-age Svalbard reindeer mandible assemblage. The tests demonstrate our methods' user-friendliness and reliability to generate reproducible, reusable datasets and accuracy in estimating reindeer age-at-death.Currently, a very important thread of research on COVID-19 is to determine the dimension of the psychopathological emotional reactions induced by the COVID-19 pandemic. A non-experimental online research project was designed to determine the predictors of the severity of psychopathological symptoms, such as depression and PTSD symptoms, and the nature of the feedback mechanism between them in groups of men, remaining in hospital isolation due to infection and at-home isolation during the COVID-19 epidemic. The presence of symptoms of depression, post-traumatic stress disorder (PTSD) and a sense of threat due to the pandemic were assessed using the following screening tests IES-R by Weiss and Marmar, PHQ-9 by Spitzer et al., and a self-constructed sliding scale for assessing COVID-19 anxiety. The study was carried out on a group of 57 firefighting cadets, hospitalized in a COVID-19 isolation room (Mage = 23.01), staying in isolation due to SARS-CoV-2 virus infection and a control group of 57 healthy men (Mage l population.Repetitive negative thinking (RNT) and addictive Facebook use have been shown to be associated with suicide ideation and suicidal behavior. The present longitudinal study aimed to investigate whether the association between addictive Facebook use and suicide-related outcomes is mediated by RNT. Data of 191 German Facebook users (M age  = 26.17, SD age  = 6.63) were assessed at two measurement time points over a one-year period (first measurement = T1, second measurement = T2) via online surveys. The significant positive association between addictive Facebook use (T1) and suicide-related outcomes (T2) was significantly mediated by RNT (T1). In contrast, a check test that included RNT (T1) as predictor and addictive Facebook use (T1) as mediator revealed no significant mediation effect. The current results demonstrate that if addictive Facebook use leads to RNT suicide ideation and attempts become likely. Therefore, RNT and addictive Facebook use should be taken into account when assessing individuals for risk of suicide.Positivity (i.e., the individual tendency to positively approach life experiences) has proven to be an effective construct applied in positive psychology. However, individuals' self-regulation may have contrasting effects on positivity. We specifically examined whether positivity could be partially explained through two aspects of motivation concerned with self-regulation locomotion (i.e., a motivational orientation concerned with movement) and assessment (i.e., a motivational orientation concerned with comparison and evaluation). Furthermore, based on previous literature that found a link between these aspects and narcissism, we examined whether "adaptive" and "maladaptive" dimensions of narcissism could mediate the effects of locomotion and assessment on increased or decreased positivity. Narcissism was defined by previous research as adaptive or maladaptive insofar as it leads or does not lead to increased psychological well-being. We estimated a mediation model with multiple independent variables and multiple mediators in a cross-sectional study with self-reported data from 190 university students. We found that both locomotion and assessment were associated with adaptive narcissism, which in turn was positively associated with positivity. However, assessment was also associated with maladaptive narcissism, which in turn was negatively associated with positivity. Relationships between aspects of self-regulation, narcissism, and positivity can have significant implications which will be discussed.Obstetricians and gynecologists are likely to be at risk of occupational distress because their quality of life is affected as a result of their experiences of assisting with traumatic births and/or providing abortions, among others. Nevertheless, there have been few studies of this group of doctors' compassion fatigue. This study aimed to examine obstetricians and gynecologists' compassion fatigue. This survey-based quantitative study examined 107 obstetricians and gynecologists' compassion fatigue. Data were collected using a demographic information form and the Compassion Fatigue Short Scale. find more This established that had low levels of compassion fatigue related to secondary trauma and job burnout, but moderate levels of it overall. Among female obstetricians and gynecologists, compassion fatigue was higher than among their male counterparts, and respondents who worked at private hospitals had higher compassion fatigue related to secondary trauma than those who worked in state-run hospitals. The data also revealed that obstetricians and gynecologists with 11-15 years' seniority scored higher on the job-burnout subdimension of compassion fatigue, and overall, than their more senior counterparts. Interestingly, however, no statistically significant differences in the participants' compassion fatigue were found to be associated with their ages, marital statuses, numbers of children, number of patients seen per day, or number of daily operations performed. Professional sharing groups that allow doctors to share their experiences and to gain awareness about their colleagues' traumas should be organized. Teamwork should also be encouraged; and various prevention strategies should also be considered.Altought compassionate care is an important factor in health care, remains an unmet need in patients. The studies have been carried out in Anglo-Saxon countries with cultural environments and health systems that are very different from Spanish-speaking contexts. The aim of this study to understand the conceptual, evaluation and clinical application nuances of compassion and compassionate care in Spanish-speaking health care settings, through a systematic review. A search of the scientific literature was carried out following the PRISMA guidelines in ProQuest Central, PubMed and Web Of Science, resulting in 295 studies, of which 27 were selected, based on the following inclusion criteria the article studied or analyzed the construct of compassion in healthcare setting and the participants were Spanish speakers or the authors spoke of the construct in Spanish. Two blinded evaluators performed the study selection process using the Covidence tool. The agreement between evaluators was in all cases satisfactory. Different definitions of the construct have been identified, that they generally share the recognition of suffering and the attempt to alleviate it. There are few studies that focus solely on the analysis of compassion, since other concepts appear that are associated with it, such as empathy and self-compassion. Further research is needed to obtain a better and greater understanding of compassionate care adapted to the perceptions of patients and health professionals in different socio-cultural contexts. In this way, instruments that measure compassionate care can be better developed and adjusted, and interventions aimed at promoting compassion can be properly assessed.This mixed-methods study explored K-12 teachers' feelings, experiences, and perspectives regarding online teaching during the COVID-19 pandemic. The study also examined teachers' perspectives of the "new normal" after COVID-19 and of what should be done to better prepare teachers for future emergencies. Both quantitative and qualitative data were collected from an online survey and follow-up interviews. A total of 107 teachers from 25 different states in the United States completed the online survey, and 13 teachers from 10 different states participated in the follow-up interviews. The results revealed teachers' feelings about online teaching and various strategies and tools they used during the early stage of the COVID-19 pandemic. The major challenges faced by teachers during the pandemic included lack of student participation and engagement (or lack of parental support), students without access to technology, concerns about students' well-being, no face-to-face interactions with students, no work-life balance, and learning new technology. Four major themes emerged regarding how to better prepare teachers for future emergencies (1) professional development for online learning, (2) technology access, (3) technology training for both teachers and students, and (4) action plans and communication. Regarding teachers' perspectives of the "new normal," five major themes emerged (1) more online or blended learning, (2) rethinking normal, (3) hygiene and social distancing, (4) smaller classes and different school schedules, and (5) uncertainty and concerns about the "new normal."
Women with lower limb loss represent a relevant and growing patient cohort with unique rehabilitation needs. These needs are emphasized in a growing body of literature and the most recent Veteran Affairs/Department of Defense clinical practice guidelines.

Women with limb loss experience greater dissatisfaction with prosthetic fit, appearance, and types of footwear they can use. There is a lack of prosthetics solutions to accommodate the desire of women to wear different footwear varieties, including high heels. The choice to wear a variety of footwear is important to attire and hence community participation. Despite these recognized challenges, women are still underserved in prosthetics research, which limits available information to guide the rehabilitation process.

This narrative review describes considerations of lower limb prosthesis prescription and use by women, and examples of current research to address these topics. Research efforts are beginning to explore factors that contribute to prosthetics prescription for women, and design creative prosthetics solutions to expand the range of available footwear options. Research is still needed to characterize the types of footwear women with limb loss prefer to use, and the effects of prosthesis designs, footwear, and lower limb loss on women mobility outcomes and community participation.

Through targeted research initiatives, scientists and clinicians can be responsive to the specific needs of women to provide evidence-based guidelines for prosthetics prescription and improve the patient-centered care after limb loss.
