Plants have a high level of developmental plasticity that allows them to respond and adapt to changes in the environment. Among the environmental cues, light controls almost every aspect of A. thaliana's life cycle, including seed maturation, seed germination, seedling de-etiolation and flowering time. Light signals induce massive reprogramming of gene expression, producing changes in RNA polymerase II transcription, alternative splicing, and chromatin state. Since splicing reactions occur mainly while transcription takes place, the regulation of RNAPII transcription has repercussions in the splicing outcomes. This cotranscriptional nature allows a functional coupling between transcription and splicing, in which properties of the splicing reactions are affected by the transcriptional process. Chromatin landscapes influence both transcription and splicing. In this review, we highlight, summarize and discuss recent progress in the field to gain a comprehensive insight on the cross-regulation between chromatin state, RNAPII transcription and splicing decisions in plants, with a special focus on light-triggered responses. We also introduce several examples of transcription and splicing factors that could be acting as coupling factors in plants. Unravelling how these connected regulatory networks operate, can help in the design of better crops with higher productivity and tolerance.HIV incidence rates in South Africa are extremely high, particularly postpartum. However, there is limited knowledge of women's HIV risk behavior postpartum. Women in age-disparate relationships may be less able to negotiate safe sex postpartum than women whose partners are similar ages because they have less relationship power. The study's purpose is to test whether being in an age-disparate relationship predicts postpartum unsafe sex and to explore relationship control and intimate partner violence (IPV) as explanatory mechanisms. Data are obtained from 516 HIV-negative participants who completed a survey during pregnancy and at 14 weeks postpartum as part of a longitudinal study in Durban. Age variables, relationship control, and IPV during pregnancy were included in a multivariate model predicting unsafe sex postpartum. We also assessed whether the hypothesized mediators explained the association between being in an age-disparate relationship and unsafe sex postpartum by using indirect effect analysis with bootstrapping. Women's mean age was 24.34 years (range = 18.03-45.36); the mean difference in ages in relationships was 3.19 years (range = -6.1 to 30.1). More than a quarter reported unsafe sex postpartum (27%). Age-disparate relationship, lower relationship control, and higher IPV were each longitudinally associated with unsafe sex. Relationship control, but not IPV, mediated the association between age-disparate relationship and unsafe sex (indirect effect [B] = 0.01, 95% confidence interval [CI] = [0.0002, 0.0283]). Age disparity, relationship control, and IPV all contributed to unsafe sex postpartum. https://www.selleckchem.com/products/pnd-1186-vs-4718.html Interventions that reduce the formation of age-disparate relationships and increase women's relationship power in pregnancy are needed to reduce women's HIV risk in the postpartum period.When parents are confronted with something as fundamental as a cancer diagnosis for their child, it is generally assumed that sharing the emotional impact of it, in the form of talking about it with the partner, is helpful and necessary to cope as an individual and a couple. However, couple communication in the context of childhood oncology is often challenging. In this qualitative research, we aimed for a better understanding of how partners experience their couple communication during treatment of their child. Thematic coding was done on in-depth interviews with 16 parents (7 couples interviewed together and 2 mothers). We found that the circumstances of the treatment period affected couple communication. In the interviews, parents provided three main meanings to their limited talking (a) because of the hospital and treatment context; (b) for self-care/self-protection related to the value of blocking emotions; and (c) because of each other. These findings invite us to rethink emotional closeness being equated with frequent or intense emotional communication in couples with a child who has cancer. This research, framed in a dialectic approach, emphasizes the value of both talking and not talking in the tense and challenging couple situation of dealing with a child's cancer diagnosis and treatment. Rather than advocating for the general promotion of open communication, our study suggests the value of hesitations to talk at certain points in the process, while also taking into account the degree of marital difficulties in offering interventions aimed at improving couple communication.The left hemisphere is known to be generally predominant in verbal processing and the right hemisphere in non-verbal processing. We studied whether verbal and non-verbal lateralization is present in haptics by comparing discrimination performance between letters and nonsense shapes. We addressed stimulus complexity by introducing lower case letters, which are verbally identical with upper case letters but have a more complex shape. The participants performed a same-different haptic discrimination task for upper and lower case letters and nonsense shapes with the left and right hand separately. We used signal detection theory to determine discriminability (d'), criterion (c) and we measured reaction times. Discrimination was better for the left hand for nonsense shapes, close to significantly better for the right hand for upper case letters and with no difference between the hands for lower case letters. For lower case letters, right hand showed a strong bias to respond "different", while the left hand showed faster reaction times. Our results are in agreement with the right lateralization for non-verbal material. Complexity of the verbal shape is important in haptics as the lower case letters seem to be processed as less verbal and more as spatial shapes than the upper case letters.Introduction YAPS™ (Youth and Pet Survivors™) is a form of virtual animal-assisted therapy (AAT), a pen pal program designed for children and adolescents with cancer and/or having a bone marrow transplant (BMT) to engage in virtual visits with a dog or a cat (who has also been treated for cancer or serious medical illness) through letter writing and pictures. The purpose of this qualitative descriptive study was to explore the experiences of YAPS participants over time and to explore how virtual AAT may be an additional or alternative intervention to the traditional form of AAT, which involves live visits with animals, primarily dogs. Method Open-ended, face-to-face interviews were conducted throughout the participants' involvement with their animal pen pal. Interviews were digitally recorded. Data were analyzed using a content analysis method. Results Fifteen children and adolescents, aged 7 to 16 years, participated. Three main themes and five subthemes were found, including connection, shared experience, and friendship.
