    The present study is a preliminary investigation assessing the associations between socioemotional adjustment and executive functioning problems in a low-income, high-risk sample of elementary students who participated in a mindful yoga practice. Mindfulness is a concept that encompasses attention within the present moment and requires acceptance and nonjudgment. Rather than being an outcome-reliant principle, it emphasizes the individual’s present state of mind and being (Kabat-Zinn, 2003). Recently, mindfulness has become a popular phenomenon in research. It has shown to be a highly effective coping strategy and mediator for cognitive, emotional, and behavioral problems (Flook, 2010; Hayes & Feldman, 2004; Broderick & Metz, 2009; Mendelson et al., 2010). However, little research has been done to assess the role mindfulness plays in children. The objective for this study was to investigate the associations between contextual stress, mindfulness, executive functioning difficulties, emotion dysregulation, and aggression. Data for these variables was reported via self-report (n=21), parent-report, and teacher-report at one time towards the end of the yoga curriculum. Mindfulness was not associated with executive functioning or emotional dysregulation. However, parent and teacher reports did reveal significant links among more aggression, executive functioning difficulties, and emotion dysregulation. Discussion notes the limitations of the current study and recommendations for improving the study design to improve the study of positive interventions for children experiencing high-stress lifestyles

    AbstractRNA interference (RNAi) provides an effective method to silence gene expression and investigate gene function. However, RNAi tools for the chicken embryo have largely been adapted from vectors designed for mammalian cells. Here we present plasmid and retroviral RNAi vectors specifically designed for optimal gene silencing in chicken cells. The vectors use a chicken U6 promoter to express RNAs modelled on microRNA30, which are embedded within chicken microRNA operon sequences to ensure optimal Drosha and Dicer processing of transcripts. The chicken U6 promoter works significantly better than promoters of mammalian origin and in combination with a microRNA operon expression cassette (MOEC), achieves up to 90% silencing of target genes. By using a MOEC, we show that it is also possible to simultaneously silence two genes with a single vector. The vectors express either RFP or GFP markers, allowing simple in vivo tracking of vector delivery. Using these plasmids, we demonstrate effective silencing of Pax3, Pax6, Nkx2.1, Nkx2.2, Notch1 and Shh in discrete regions of the chicken embryonic nervous system. The efficiency and ease of use of this RNAi system paves the way for large-scale genetic screens in the chicken embryo

    Importance: Large cohorts of patients with active cancers and COVID-19 infection are needed to provide evidence of the association of recent cancer treatment and cancer type with COVID-19 mortality. // Objective: To evaluate whether systemic anticancer treatments (SACTs), tumor subtypes, patient demographic characteristics (age and sex), and comorbidities are associated with COVID-19 mortality. // Design, Setting, and Participants: The UK Coronavirus Cancer Monitoring Project (UKCCMP) is a prospective cohort study conducted at 69 UK cancer hospitals among adult patients (≥18 years) with an active cancer and a clinical diagnosis of COVID-19. Patients registered from March 18 to August 1, 2020, were included in this analysis. // Exposures: SACT, tumor subtype, patient demographic characteristics (eg, age, sex, body mass index, race and ethnicity, smoking history), and comorbidities were investigated. // Main Outcomes and Measures: The primary end point was all-cause mortality within the primary hospitalization. // Results: Overall, 2515 of 2786 patients registered during the study period were included; 1464 (58%) were men; and the median (IQR) age was 72 (62-80) years. The mortality rate was 38% (966 patients). The data suggest an association between higher mortality in patients with hematological malignant neoplasms irrespective of recent SACT, particularly in those with acute leukemias or myelodysplastic syndrome (OR, 2.16; 95% CI, 1.30-3.60) and myeloma or plasmacytoma (OR, 1.53; 95% CI, 1.04-2.26). Lung cancer was also significantly associated with higher COVID-19–related mortality (OR, 1.58; 95% CI, 1.11-2.25). No association between higher mortality and receiving chemotherapy in the 4 weeks before COVID-19 diagnosis was observed after correcting for the crucial confounders of age, sex, and comorbidities. An association between lower mortality and receiving immunotherapy in the 4 weeks before COVID-19 diagnosis was observed (immunotherapy vs no cancer therapy: OR, 0.52; 95% CI, 0.31-0.86). // Conclusions and Relevance: The findings of this study of patients with active cancer suggest that recent SACT is not associated with inferior outcomes from COVID-19 infection. This has relevance for the care of patients with cancer requiring treatment, particularly in countries experiencing an increase in COVID-19 case numbers. Important differences in outcomes among patients with hematological and lung cancers were observed

    Com o diabo no corpo: os terríveis papagaios do Brasil colônia

    Desde a Antiguidade, papagaios, periquitos e afins (Psittacidae) fascinaram os europeus por seu vivo colorido e uma notável capacidade de interação com seres humanos. A descoberta do Novo Mundo nada faria além de acrescentar novos elementos ao tráfico de animais exóticos há muito estabelecido pelos europeus com a África e o Oriente. Sem possuir grandes mamíferos, a América tropical participaria desse comércio com o que tinha de mais atrativo, essencialmente felinos, primatas e aves - em particular os papagaios, os quais eram embarcados em bom número. Contudo, a julgar pelos documentos do Brasil colônia, esses voláteis podiam inspirar muito pouca simpatia, pois nenhum outro animal - exceto as formigas - foi tantas vezes mencionado como praga para a agricultura. Além disso, alguns psitácidas mostravam-se tão loquazes que inspiravam a séria desconfiança de serem animais demoníacos ou possessos, pois só três classes de entidades - anjos, homens e demônios - possuíam o dom da palavra. Nos dias de hoje, vários representantes dos Psittacidae ainda constituem uma ameaça para a agricultura, enquanto os indivíduos muito faladores continuam despertando a suspeita de estarem possuídos pelo demônio. Transcendendo a mera curiosidade, essa crença exemplifica o quão intrincadas podem ser as relações do homem com o chamado “mundo natural”, revelando um universo mais amplo e multifacetado do que se poderia supor a princípio. Nesse sentido, a existência de aves capazes de falar torna essa relação ainda mais complexa e evidencia que as dificuldades de estabelecer o limite entre o animal e o humano se estendem além dos primatas e envolvem as mais inusitadas espécies zoológicas.Since ancient times, parrots and their allies (Psittacidae) have fascinated Europeans by their striking colors and notable ability to interact with human beings. The discovery of the New World added new species to the international exotic animal trade, which for many centuries had brought beasts to Europe from Africa and the Orient. Lacking large mammals, tropical America participated in this trade with its most appealing species, essentially felines, primates and birds - especially parrots - which were shipped in large numbers. It should be noted, however, that at times these birds were not well liked. In fact, according to documents from colonial Brazil, only the ants rank higher than parrots as the animals most often mentioned as agricultural pests. On the other hand, some of these birds were so chatty that people suspected them to be demonic or possessed animals, since only three classes of beings - angels, men and demons - have the ability to speak. Nowadays, several Psittacidae still constitute a threat to agriculture, and the suspicion that extremely talkative birds were demon possessed has also survived. More than a joke or a mere curiosity, this belief exemplifies how intricate man’s relationships with the “natural world” may be. In this sense, the existence of birds that are able to speak adds a further twist to these relationships, demonstrating that the problem of establishing a boundary between the animal and the human does not only involve primates, but also includes some unusual zoological species

    Examined an interpersonal-process view of depression by assessing 60 undergraduates\u27 reactions to a request for help from a hypothetical depressed or nondepressed person with whom they had been acquainted for a relatively short (2 wks) or long (1 yr) period of time. Ss responded to each of the 4 hypothetical persons by indicating their probable affective reactions to the request, the number of minutes they would be willing to help, their desire for future social contact with the hypothetical person, and their expectations of future requests for help. Results indicate that Ss felt significantly more concern and were willing to provide significantly more time for long-term acquaintances. Requests from depressed persons elicited significantly more anger and social rejection but equal amounts of concern and willingness to help. This mixed response pattern was interpreted as providing partial support for an interpersonal-process view of depression. A path analysis provided limited support for J. C. Coyne\u27s (see record 1979-01146-001) hypothesis that rejection of depressed persons results from the negative mood they induce in others

    This experiment examined an interpersonal-process view of depression by assessing subjects\u27 reactions to a request for help from a hypothetical person with whom they had been acquainted for a relatively short (2 weeks) or long (1 year) period of time and who had been depressed for either a relatively short (a few days) or long (most of 9 months) period of time. Subjects responded to each of the four hypothetical persons by indicating their probable affective reactions to the request, the number of minutes they would be willing to help, their desire for future social contact, and their expectations of future requests for help. Requests from long-duration depressives elicited significantly more anger regardless of length of acquaintance. Duration of depression × length of acquaintance interaction effects supported the prediction of a reduction in social support and an increase in rejection of the depressed person over the course of a relatively long depressive episode. Path analyses provided limited support for the hypothesis that the effect of duration of depression on willingness to help and desire for future contact is mediated by affective reactions to the request for help
