Abstract Oribatida s.l. represents one of the most species-rich mite lineages, including two recognized groups: oribatid mites (Oribatida s.s., non-astigmatan oribatids) and astigmatid mites (Astigmata). However, the relationship between these two groups has been debated. Here, we sequenced the complete mitochondrial (mt) genome of one oribatid mite and one astigmatid mite, retrieved complete mt genomes of three oribatid mites, and compared them with two other oribatid mites and 12 astigmatid mites sequenced previously. We find that gene orders in the mt genomes of both oribatid mites and astigmatid mites are rearranged relative to the hypothetical ancestral arrangement of the arthropods. Based on the shared derived gene clusters in each mt genome group, rearranged mt genomes are roughly divided into two groups corresponding to each mite group (oribatid mites or astigmatid mites). Phylogenetic results show that Astigmata nested in Oribatida. The monophyly of Astigmata is recovered, while paraphyly of Oribatida s.s. is observed. Our results show that rearranged gene orders in the mt genomes characterize various lineages of oribatid mites and astigmatid mites, and have potential phylogenetic information for resolving the high-level (cohort or supercohort) phylogeny of Oribatida.

Abstract Background: Mitochondrial (mt) genomes of Sarcoptiformes mites typically contain 37 genes. Loss of genes is rare in Sarcoptiformes mite mt genomes, but two of the six previously reported oribatid mites (Acariform Order Sarcoptiformes) are reported to have lost part of their tRNA genes. To determine whether these tRNA genes were indeed lost and whether the loss of tRNAs is universal, we re-annotated all of the available oribatid mites and sequenced the mt genome of Oribatula sakamorii. Methods: The mitogenome of O. sakamorii was sequenced with Illumina Hiseq sequencer. The mt tRNA gene annotated using multi-software combined with manual annotation approach. Phylogenetic analyses of maximum likelihood (ML) and Bayesian inference (BI) were performed with both concatenated nucleotide and amino acid sequences.Results: Mt genomes of O. sakamorii contain 37 genes including 22 tRNA genes. We were able to identify all of the mt tRNA genes that were reported as lost in Steganacarus magnus and Paraleius leontonychus, and revealed some atypical tRNAs annotation errors in oribatid mites. Oribatid mite mt genomes are characterized by low rates of gene rearrangement, with six or seven gene blocks conserved between all of the oribatid mite species and the mt genome of ancestral arthropod. Considering only the relative order of the major genes (PCGs, rRNAs), only one gene or two genes were rearranged relative to the ancestral genome. Both CREx analysis and phylogenetic results supported the origin of the Astigmata within the Oribatida. We also explored the phylogenetic relationships among all of the available oribatid mites and the results also confirm the systematic position of Hermannia in the Crotonioidea superfamily. This is also supported by synapomorphic gene derived boundary.Conclusions: The tRNA "lost" phenomenon is not universal in oribatid mites. Instead of loss, we found that the highly atypical secondary structure of inferred mt tRNA genes makes them unidentifiable by a single type of tRNA search program. Multi-software combined with manual annotation approach can improve the accuracy of tRNA gene annotation. Besides, we determined the correct systematic position of Hermannia and supported the origin of astigmatid mites was from oribatid mites.

Forest sites in Northwestern Argentinean Patagonia were surveyed to determine the oribatid mite fauna. A taxonomic inventory of oribatid mites was carried out in Northwestern Argentinean Patagonia to establish the taxonomic diversity, for increasing the knowledge of their distribution, detecting new species and assessing environmental effects on the oribatid mite community. Eleven sampling sites in nearly pure forests of Austrocedrus chilensis, Nothofagus dombeyi, Nothofagus antarctica were selected as these are among the most recurrent arboreal species found in this region. Samples of leaf litter, soil and pitfall traps contents were taken from each forest. Fifty-five oribatid species, belonging to 46 genera in 28 families, were found. Nine species are new records for Argentina and one for continental Argentina. Thirty-two species were recorded in A. chilensis forests, 35 in N. dombeyi forests and 20 in N. antarctica forests. Fifty species were found in leaf litter, 35 in soil and eight in pitfall traps. Fourteen species were recorded exclusively in leaf litter, one in soil and four in pitfall traps. A high level of endemism is confirmed as nearly 62 % of collected species have previously been found only in Southern Andes supporting the existence of an associated autochthonous oribatid fauna.

AbstractBackground: Comprehensive cardiac rehabilitation (CR) is a process designed to restore full physical, psychological and social activity and to reduce cardiovascular risk factors. Fear of movement may contribute to the occurrence and intensification of hypokinesia, and consequently affect the effectiveness of therapy. The aim of the study was to determine the level of barriers of physical activity in patients undergoing cardiac rehabilitation. The relationship between selected determinants (age and health selfassessment) and the kinesiophobia level were also examined.Material/Methods: 115 people aged 40-84 years were examined: 50 females (x = 63.46; SD = 11.19) and 65 males (x = 64.65; SD = 10.59) - patients undergoing cardiac rehabilitation at the Upper-Silesian Medical Centre in Katowice. In the present study, the Polish version of questionnaires: Kinesiophobia Causes Scale (KCS) and Short Form Health Survey (SF-36) were used. Questionnaires were supplemented by authors’ short survey.Results: The patients presented an elevated level of kinesiophobia, both in general as well as in individual components. In women, the kinesiophobia level was higher than in men. The psychological domain was a greater barrier of physical activity than the biological one. Strong, negative correlations of psychological and biological domains of kinesiophobia to physical functioning (SF-36) were noted in women. In the case of men, correlations were weaker, but also statistically significant.Conclusions: 1. Sex differentiates patients in their kinesiophobia level 2. Poor self-assessment of health is associated with a greater intensification of kinesiophobia 3. A high level of kinesiophobia may negatively affect cardiac rehabilitation process

The purpose of the research is to study the possibility of predicting the development of aerobic endurance of athletes through a comparative analysis of the outcomes of genetic and computerized testing. Methods and organization of the research. In our research, we used scientific and methodological literature, as well as the outcomes of competitive activity and genetic analysis of a particular athlete. The total number of survey respondents was 158 people including athletes (n = 85) and coaches (n = 73). Results and discussion. Some authors find the relationship between the ability to develop and manifest endurance and the presence of the appropriate alleles of genes: ACE I, ACNT X, ACNT3 (RX, XX), ADRA2A, AMPDI C, PGC1A Gly, NFATC4, UCP2. Most studies reveal the relationship between the ACE gene and endurance supported by the I allele. Genetic foresight of the possibility of developing aerobic endurance of athletes can become the framework for the application of an individual approach in sport training, and contribute to the development of techniques aimed at the refinement of physical qualities. The modern approach to the coaching and competitive activities of athletes should include both genetic and functional studies of the human body. Conclusion. Sport forecast cannot be based solely on genetic testing results. The presence of polymorphisms in one or more genes associated with sport activity is the platform for good performance in a particular sport, but the actual manifestation of genetic predisposition depends on many factors. These factors include nutrition, daily routine and competent organization of the training process, which requires a high level of theoretical and practical competency of coaches in the field of biomedical education.

Abstract Background The transmission dynamics and severity of coronavirus disease 2019 (COVID-19) pandemic is different across countries or regions. Differences in governments’ policy responses may explain some of these differences. We aimed to compare worldwide government responses to the spread of COVID-19, to examine the relationship between response level, response timing and the epidemic trajectory. Methods Free publicly-accessible data collected by the Coronavirus Government Response Tracker (OxCGRT) were used. Nine sub-indicators reflecting government response from 148 countries were collected systematically from January 1 to May 1, 2020. The sub-indicators were scored and were aggregated into a common Stringency Index (SI, a value between 0 and 100) that reflects the overall stringency of the government’s response in a daily basis. Group-based trajectory modelling method was used to identify trajectories of SI. Multivariable linear regression models were used to analyse the association between time to reach a high-level SI and time to the peak number of daily new cases. Results Our results identified four trajectories of response in the spread of COVID-19 based on when the response was initiated: before January 13, from January 13 to February 12, from February 12 to March 11, and the last stage—from March 11 (the day WHO declared a pandemic of COVID-19) on going. Governments’ responses were upgraded with further spread of COVID-19 but varied substantially across countries. After the adjustment of SI level, geographical region and initiation stages, each day earlier to a high SI level (SI > 80) from the start of response was associated with 0.44 (standard error: 0.08, P < 0.001, R2 = 0.65) days earlier to the peak number of daily new case. Also, each day earlier to a high SI level from the date of first reported case was associated with 0.65 (standard error: 0.08, P < 0.001, R2 = 0.42) days earlier to the peak number of daily new case. Conclusions Early start of a high-level response to COVID-19 is associated with early arrival of the peak number of daily new cases. This may help to reduce the delays in flattening the epidemic curve to the low spread level. Graphic abstract

Abstract Family caregivers of older people living with dementia are relatives, friends, or neighbors who provide assistance related to this condition, but who are unpaid for the services they provide. Although caregiving could be personally rewarding, many caregivers report a high level of strain. Compared to caregivers of older adults who do not have dementia, family caregivers of older people living with dementia report lower quality-of-life (QoL). In a published systematic review examining the relationship between family caregiver QoL and the quality of care provided, only one study was found to be somewhat relevant. The study suggested that the primary reason for an absence of research into the link between family caregiver QoL and quality of care was the absence of a questionnaire for measuring quality of care in dementia. Therefore, any attempt to investigate the impact of caregiver QoL on the care provided to older people with dementia must first address the lack of an instrument to measure quality of care. To address this issue, we interviewed approximately 20 family caregivers in order to elicit feedback on measurements and interpretation of the quality of care provided by family caregivers of older people living with dementia. Content analysis of the interview transcripts revealed that the quality of relationships with family, caregiver availability to provide or supervise care, and availability of paid or volunteer help are important for the quality of care provided. These results have important implications, particularly for the development of an instrument to measure quality of care in dementia.

Recognizing the importance of knowledge sharing, this study adopted social learning and social exchange perspectives to understand when employees may engage in knowledge sharing. Using data collected from 192 employees in various South Korean organizations, the findings demonstrate that there is a positive relationship between supervisor knowledge sharing and employee knowledge sharing. As employees perceive a high level of supervisor knowledge sharing, they are likely to engage in knowledge sharing based on social learning and social exchange theories. Furthermore, the study explores the moderating effects of learning goal orientation and affective organizational commitment in the relationship between supervisor knowledge sharing and employee knowledge sharing. The result supports the hypothesis that the relationship between supervisor knowledge sharing and employee knowledge sharing is strengthened when there is a high level of affective organizational commitment. Employees who obtain valuable knowledge from their supervisors are likely to engage in knowledge sharing when they are emotionally attached to their organization. However, in contrast to the hypothesis, the positive relationship between supervisor knowledge sharing and employee knowledge sharing was stronger at the lower levels of learning goal orientation (LGO) than at the higher levels of LGO.
