There have been recent reports of successful use of fragmented autogenous dentin being used as a graft material in implant dentistry. This may reduce morbidity and the need for a second donor ste or for the use of alloplasts or allografts. This article discusses the background, preparation and use of autogenous dentin as an oral osseous graft material. A series of cases where autogenous dentin is used to graft immediate dental implant sites is presented. After 21 months one case biopsy showed only bone and no remnant dentin. Pulverized autogenous dentin may be an appropriate graft material in implant dentistry.Identification of species involved in cadaveric decomposition, such as scavenger Diptera, is a fundamental step for the use of entomological evidence in court. Identification based on morphology is widely used in forensic cases; however, taxonomic knowledge of scavenger fauna is poor for many groups and for many countries, particularly Neotropical ones. A number of studies have documented the utility of a DNA barcoding strategy to assist in the identification of poorly known and diverse groups, particularly in cases involving immature states or fragmented organisms. To provide baseline knowledge of the diversity of scavenger Diptera in the Valley of Mexico, we generated a DNA barcode collection comprised of sequences of the cytochrome c oxidase subunit 1 (COI) gene for all families sampled at a nature reserve located in this region. We collected and identified specimens on the basis of morphology and a species delimitation analysis. Our analyses of 339 individuals delineated 42 species distributed across nine families of Diptera. The richest families were Calliphoridae (9 species), Sarcophagidae (7 species), and Phoridae (6 species). We found many of the species previously recorded for the Valley of Mexico, plus 18 new records for the region. Our study highlights the utility of DNA barcoding as a first-step strategy to assess species richness of poorly studied scavenger fly taxa.Adolescence is marked by changes in decision-making and perspective-taking abilities. Although adolescents make more adaptive decisions with age, little is understood about how adolescents make adaptive decisions that impact others and how this behavior changes developmentally. Functional coupling between reward (e.g., VS) and "social brain" (e.g., TPJ/pSTS, mPFC) systems may be differentially shape adaptive risks for the self and other. A total of 173 participants completed between 1-3 sessions across three waves (a total of 433 behavioral and 403 fMRI data points). During an fMRI scan, adolescents completed a risky decision-making task where they made risky decisions to win money for themselves and their parent. The risky decisions varied in their expected value (EV) of potential reward. Results show that from the 6th through 9th grades, adolescents took increasingly more adaptive risks for themselves than for their parent. Additionally, greater VS-TPJ/pSTS and VS-mPFC connectivity that tracks EV when making risky decisions for themselves in 6th grade, but a lower VS-mPFC connectivity in 9th grade, predicted greater adaptive risk taking for their parent. This study contributes to our understanding of the self as a neural proxy for promoting adaptive social behaviors in youth.In the developing cerebral cortex, how progenitors that seemingly display limited diversity end up producing a vast array of neurons remains a puzzling question. The prevailing model suggests that temporal maturation of progenitors is a key driver in the diversification of the neuronal output. However, temporal constraints are unlikely to account for all diversity, especially in the ventral and lateral pallium where neuronal types significantly differ from their dorsal neocortical counterparts born at the same time. In this study, we implemented single-cell RNAseq to sample the diversity of progenitors and neurons along the dorso-ventral axis of the early developing pallium. We first identified neuronal types, mapped them on the tissue and determined their origin through genetic tracing. We characterised progenitor diversity and disentangled the gene modules underlying temporal versus spatial regulations of neuronal specification. Finally, we reconstructed the developmental trajectories followed by ventral and dorsal pallial neurons to identify lineage-specific gene waves. Our data suggest a model by which discrete neuronal fate acquisition from a continuous gradient of progenitors results from the superimposition of spatial information and temporal maturation.Nondisclosure of prognosis of advanced cancer is commonly practiced in some Asian cultures including India; but research is limited. To describe experiences of Indian oncologists in discussing cancer prognosis with people with cancer and their caregivers, with a focus on barriers and facilitators of prognostic discussions. Thirty oncologists practicing in South India, Hyderabad participated in semi-structured interviews; and analyzed using Interpretative Phenomenological Analysis. Barriers included system-level, patient-level, and physician-level challenges as obstructions to open and honest interactions around cancer prognosis. Most of the barriers focused on communication-related challenges. Lack of communication skills training for providers coupled with over-reliance on use of euphemisms, hesitation in communicating with "weak" patient, and struggles to establish healthcare proxy described communication-related barriers. selleckchem The study also described factors including family involvement in cancer care and empathic communication as facilitators of honest and open communication about prognosis. In particular, rapport building and getting to know the patient, use of empathic communication, engaging in gradual and individualized disclosure, and balancing hope with honesty were communication-related facilitators that aid open communication with patients with cancer and their caregivers about prognosis and plan of care. Results provide implications for development of communication skills trainings for oncology physicians in India. Adapting, delivering, and evaluating existing communication skills training programs, particularly around discussions of prognosis and goals of care is a requisite step for providing patient-centered and supportive care to patients with cancer and their caregiving families.
