The application of graph theory in structural biology offers an alternative means of studying 3D models of large macromolecules such as proteins. The radius of gyration, which scales with exponent [Formula see text], provides quantitative information about the compactness of the protein structure. In this study, we combine two proven methods, the graph-theoretical and the fundamental scaling laws, to study 3D protein models. This study shows that the mean node degree (MND) of the protein graphs, which scales with exponent 0.038, is scale-invariant. In addition, proteins that differ in size have a highly similar node degree distribution. Linear regression analysis showed that the graph parameters (radius, diameter, and mean eccentricity) can explain up to 90% of the total radius of gyration variance. Thus, the graph parameters of radius, diameter, and mean eccentricity scale match along with the same exponent as the radius of gyration. The main advantage of graph eccentricity compared to the radius of gyration is that it can be used to analyze the distribution of the central and peripheral amino acids/nodes of the macromolecular structure.Although the onset of the coronavirus disease 2019 (COVID-19) drastically altered the daily lives of much of the world--requiring masking, additional sanitation behaviors, and social isolation-patients who have undergone hematopoietic stem cell transplantation (HSCT) were already experts in these precautionary behaviors. HSCT provides a potential cure for some hematologic malignancies. However, it entails a protracted hospitalization, substantial physical side effects, and a decline in psychological well-being and quality of life. The COVID-19 pandemic has tightened many of the already strict procedures put in place for HSCT patients in order to protect their vulnerable immune systems, which could lead to more distress. Alternatively, exposure to this public health crisis may unlock the lives of HSCT survivors for their communities and healthcare providers to further inspire HSCT care built on a stronger foundation of empathy.Wischik presents an extensive reply to our paper on conscientious objection, which explores the implications of distinguishing 'medical acts' from 'socioclinical acts'. He provides an extensive legal analysis of the issues surrounding conscientious objection, drawing on the concepts of professional practice and consequentialism. Invoking some of these concepts, we respond and demonstrate that Wischik does not seriously engage with our argument. Instead, he merely proffers his preference for legal positivism, which - when viewed as the fount of justice (as Wischik seems to hold) instead of a tool in its service - necessarily bases rightness on might rather than truth. https://www.selleckchem.com/Proteasome.html We also argue that in several important areas, Wischik is factually mistaken.Intimate partner violence (IPV) is a major human rights and public health problem which occurs at exceptionally high rates among tertiary students. Attitudes toward IPV are increasingly being recognized as a key risk factor for IPV and targeted in IPV prevention programs on college and university campuses. Understanding the influence of culture on attitudes toward IPV is necessary to change attitudes supportive of IPV and ultimately reduce the occurrence of IPV in the student population. This review sought to systematically identify, appraise, and synthesize research studies examining cross-cultural differences in attitudes toward IPV among tertiary students. A comprehensive search of nine electronic databases was conducted from inception to 15 May 2019. Studies were required to have compared attitudes toward IPV (e.g., acceptance or justification of IPV) among two or more cultural groups (based on country, race, or ethnicity) of tertiary students. Eighteen articles met eligibility criteria for the review, representing over 6,800 students. The studies provide considerable evidence that student attitudes toward IPV differ across cultures. Students in the United States and ethnic majority students in the United States generally showed less accepting attitudes toward IPV than their counterparts in other countries and ethnic minority groups. The particular contexts in which IPV is justified may reflect cultural values and norms. The findings have important implications for prevention and intervention strategies aimed at improving attitudes toward IPV among tertiary students.Although cognitive impairment is common among persons with heart failure and negatively impacts self-care, hospitalization, and mortality, the associations between cognitive impairment and insomnia symptoms are not clearly understood. The purpose of this study was to explore these associations and examine if they are maintained after adjusting for relevant sociodemographic, clinical, and lifestyle factors. Guided by the Neurocognitive model of insomnia and sleep and the self-care conceptual model, a cross-sectional data analysis using parametric testing was conducted on the Health and Retirement Study wave 2016. Difficulty initiating sleep and early morning awakening, but not difficulty maintaining sleep were significantly associated with poorer cognitive performance in the bivariate and multivariate analysis. Our results are suggestive of different phenotypes of insomnia symptoms that may have different associations with cognition in persons with heart failure. Further research using objective measurements of insomnia symptoms and detailed neuropsychiatric testing of cognition is needed to confirm this conclusion.Glioblastoma multiforme (GBM) is the most frequent primary malignant brain tumour prevalent in humans, that exhibits aggressive cell proliferation and rapid invasion of normal brain tissue. Despite aggressive therapeutic approaches consisting of maximum safe surgical resection followed by radio-chemotherapy with temozolomide (TMZ), more than 95% of GBM patients die within 5 years after diagnosis. In most cases, the therapy is not able to counteract the growth and invasiveness of the tumour, which relapses after an interval of time that varies from patient to patient. An increasing number of evidence indicates that natural substances exhibited effective anti-tumour functions and might be successfully used in the treatment of GBM. This review summarizes some natural substances lactoferrin, hispolon, aloe-emodin and tea tree oil; all these show a growth inhibition and synergistic effect when together with TMZ, (the most commonly used alkylating drug for the treatment of glioblastoma) were administered to U87MG glioblastoma cell line in vitro and in murine animal model.

The most popular fictions produced in the last decades contain such a fictional world. They can be found in all fictional media, from novels (e.g., Lord of The Ring, Harry Potter) to films (e.g., Star Wars, Avatar), video games (e.g., The Legend of Zelda, Final Fantasy), graphic novels (e.g., One piece, Naruto) and TV series (e.g., Star Trek, Game of Thrones), and they date as far back as ancient literature (e.g., the Cyclops Islands in The Odyssey, 850 BCE). Why such a success? Why so much attention devoted to nonexistent worlds? In this article, we propose that imaginary worlds co-opt our preferences for exploration, which have evolved in humans and non-human animals alike, to propel individuals toward new environments and new sources of reward. Humans would find imaginary worlds very attractive for the very same reasons, and under the same circumstances, as they are lured by unfamiliar environments in real life. After reviewing research on exploratory preferences in behavioral ecology, environmental aesthetics, neuroscience, and evolutionary and developmental psychology, we focus on the sources of their variability across time and space, which we argue can account for the variability of the cultural preference for imaginary worlds. This hypothesis can therefore explain the way imaginary worlds evolved culturally, their shape and content, their recent striking success, and their distribution across time and populations.
There is growing evidence that individuals within populations can vary in both habitat use and movement behavior, but it is still not clear how these two relate to each other. The aim of this study was to test if and how individual bats in a Stunira lilium population differ in their movement activity and preferences for landscape features in a correlated manner.

We collected data on movements of 27 individuals using radio telemetry. We fitted a heterogeneous-space diffusion model to the movement data in order to evaluate signals of movement variation among individuals.

S. lilium individuals generally preferred open habitat with Solanum fruits, regularly switched between forest and open areas, and showed high site fidelity. Movement variation among individuals could be summarized in four movement syndromes (1) average individuals, (2) forest specialists, (3) explorers which prefer Piper, and (4) open area specialists which prefer Solanum and Cecropia.

Individual preferences for landscape features plus food resource and movement activity were correlated, resulting in different movement syndromes. Individual variation in preferences for landscape elements and food resources highlight the importance of incorporating explicitly the interaction between landscape structure and individual heterogeneity in descriptions of animal movement.

Recent clinical trial failures, difficult diagnosis, uncertain etiology, and lack of curative therapies prompted us to re-examine other hypotheses of neurodegenerative pathogenesis. Recent reports establish that mitochondrial and calcium dysregulation occur early in many neurodegenerative diseases (NDDs), including Alzheimer's disease, Parkinson's disease, Huntington's disease, and others. However, causal molecular evidence of mitochondrial and metabolic contributions to pathogenesis remains insufficient. Here we summarize the data supporting the hypothesis that mitochondrial and metabolic dysfunction result from diverse etiologies of neuropathology. We provide a current and comprehensive review of the literature and interpret that defective mitochondrial metabolism is upstream and primary to protein aggregation and other dogmatic hypotheses of NDDs. Finally, we identify gaps in knowledge and propose therapeutic modulation of mCa2+ exchange and mitochondrial function to alleviate metabolic impairments and treat NDDs.
Research into predictors of outcome in eating disorders (ED) has shown conflicting results, with few studies of long-term predictors and the possible importance of psychological variables that may act as risk- and maintenance factors.

To identify baseline predictors of ED remission nine years after initial clinical assessment using self-report measures of ED psychopathology, psychiatric symptoms, and self-image in a sample of adult ED patients (N = 104) treated at specialist units in Stockholm, Sweden. Sixty patients participated in the follow-up, of whom 41 patients (68%) had achieved remission.

Results suggested that the only significant predictor of diagnostic remission after nine years was initial levels of self-blame.

In order to ensure long-term recovery in ED it may be important for clinicians to widen their therapeutic repertoire and utilise techniques that reduce self-blame and increase self-compassion. It is difficult to predict how an eating disorder will develop, and research has found varying factors that affect the outcome of the condition.

In contrast, the rate of mutation induced by NDEA was higher in spel1(-/-) flies than in spel1(+/-) flies. These results suggest that in Drosophila, the MutS homologue protein recognises methylated DNA lesions more efficiently than ethylated ones, and that MMR might facilitate mutational chromosomal recombination due to DNA double-strand breaks via the futile cycle induced by MutS recognition of methylated lesions. © The Author(s) 2020.

A single surgical access may have limitations and jeopardize patients. OBJECTIVE To present a series of patients to illustrate our individually tailored treatment concept and decision pathway. METHODS Retrospectively, clinical findings and imaging were related to surgical features and outcome. An algorithm for choice of approach was established. RESULTS From 2012 to 2017, we operated on n = 13 patients with retroperitoneal tumors, of these n = 9 were included (n = 6 female, n = 3 male). Histological findings included n = 2 schwannomas, n = 2 malignant peripheral nerve sheath tumors, n = 1 non-origin sarcoma, n = 1 perineurioma, n = 1 intraneural ganglion cyst, n = 1 lymphoma, and n = 1 paraganglioma. In n = 6 patients, we used a monoportal (retroperitoneal/transperitoneal) approach; in n = 2 patients, a biportal retroperitoneal to inguinal/transperitoneal to dorsal approach; and in n = 1 patient, a triportal transperitoneal to dorsal to gluteal approach. In n = 2 patients, we performed an open biopsy only; in n = 2 patients, a tumor enucleation; in n = 3 patients, a subtotal function-sparing resection; in n = 1 patient, a complete resection; and in n = 1 patient, intraneural decompression. In n = 1 patient, a new motor deficit appeared. n = 4 patients required further radio-oncological treatment. n = 8/9 patients are alive without tumor progress or recurrence. CONCLUSION Retroperitoneal nerve or nerve-associated tumors encompass multiple entities. https://www.selleckchem.com/products/azd7648.html Depending on suspected histology and tumor extension, extensile or combined surgical approaches may be necessary.

Our objective was to describe the transition readiness of children and young adults with inflammatory bowel disease (IBD) and examine its associations with demographic factors, IBD activity, and measures of physical, psychological, and social health. METHODS We recruited children ages 12 to 17 and young adults ages 18 to 20 from 2 internet-based cohorts sponsored by the Crohn's & Colitis Foundation. Participants self-reported demographics, IBD activity, transition readiness, health-related quality of life, and Patient-Reported Outcomes Information Systems domains of physical, psychological, and social health. RESULTS Among 361 pediatric and 119 adult participants, age and female sex were associated with transition readiness. The association was greater in the pediatric cohort. Having IBD in remission was associated with worse transition readiness in the pediatric cohort only (beta = 0.3; P = 0.003). Health-related quality of life and Patient-Reported Outcomes Information Systems measures of fatigue, pain interference, and sleep disturbance were not associated with transition readiness in either children or adults. We observed few small associations between psychological or social health and transition readiness. Better transition readiness was associated with greater anxiety in adults (beta = -0.02; P = 0.02) and greater peer relationships among children (beta = 0.01; P = 0.009). CONCLUSIONS In children and young adults with IBD, transition readiness was associated with older age and female sex. Associations between transition readiness and physical, psychological, and social health were either small, inconsistent across age groups, or nonexistent. © 2020 Crohn’s & Colitis Foundation.

ARGs can be spread via HGT, through mechanisms are known and have been shown to depend on the environment, bacterial communities, and mobile genetic elements. Classically, HGT mechanisms include conjugation, transformation, and transduction; more recently, membrane vesicles (MVs) have been reported as DNA reservoirs implicated in interspecies HGT. Here, we review the current knowledge on the HGT mechanisms with a focus on the role of MVs and the methodological innovations in the HGT research. © FEMS 2020.During biological invasions, invasive populations can suffer losses of genetic diversity that are predicted to negatively impact their fitness/performance. Despite examples of invasive populations harboring lower diversity than conspecific populations in their native range, few studies have linked this lower diversity to a decrease in fitness. Using genome sequences, we show that invasive populations of the African fig fly, Zaprionus indianus, have less genetic diversity than conspecific populations in their native range and that diversity is proportionally lower in regions of the genome experiencing low recombination rates. This result suggests that selection may have played a role in lowering diversity in the invasive populations. We next use interspecific comparisons to show that genetic diversity remains relatively high in invasive populations of Z. indianus when compared to other closely related species. By comparing genetic diversity in orthologous gene regions, we also show that the genome-wide landscape of genetic diversity differs between invasive and native populations of Z.
