    Introduction When circumstances change in the blink of an eye, educators are accustomed to monitoring and adjusting to do whatever it takes to help students be successful. Little did we know that the requisite skills of being nimble, flexible problem solvers would be stretched to the limit as educators around the world addressed the massive educational changes that occurred in response to the global pandemic. Through their commitment to following best practices in educator preparation and ongoing collaboration with many stake holders, the West Texas A & M University’s (WTAMU’s) Educator Preparation Program (EPP) faced the challenges of the COVID-19 quarantine while supporting 90 clinical teachers in completing their vital clinical teaching experience. This included making an overnight shift from “actual” face-to-face teaching to delivering lessons in new “authentic” virtual learning environments

    Complete RNA inverse folding: computational design of functional hammerhead ribozymes

    Full text link
    Nanotechnology and synthetic biology currently constitute one of the most innovative, interdisciplinary fields of research, poised to radically transform society in the 21st century. This paper concerns the synthetic design of ribonucleic acid molecules, using our recent algorithm, RNAiFold, which can determine all RNA sequences whose minimum free energy secondary structure is a user-specified target structure. Using RNAiFold, we design ten cis-cleaving hammerhead ribozymes, all of which are shown to be functional by a cleavage assay. We additionally use RNAiFold to design a functional cis-cleaving hammerhead as a modular unit of a synthetic larger RNA. Analysis of kinetics on this small set of hammerheads suggests that cleavage rate of computationally designed ribozymes may be correlated with positional entropy, ensemble defect, structural flexibility/rigidity and related measures. Artificial ribozymes have been designed in the past either manually or by SELEX (Systematic Evolution of Ligands by Exponential Enrichment); however, this appears to be the first purely computational design and experimental validation of novel functional ribozymes.

    Purpose: Previous research investigating a 50% down payment policy for elective surgeries demonstrated that a substantial number of self pay patients failed to receive recommended surgery due to the down payment cost. The current study analyzes the effect of a new, more liberal sliding scale down payment policy implemented at this same public hospital and assesses the impact on health care access for self pay patients. Methods: Data was collected from the admissions office and the pre-operative assessment office where elective surgery cancellation reasons were recorded. Chi-square tests were used to determine the statistical significance between data sets. Results: 448 recorded cancellations were documented over an 8 month period. Of those records, 6.9% (n=31) were self pay patients and 93% (n=417) had insurance. Of the 31 self pay patients, 51.6% (n=16) had cancelled stating financial reasons, while 4.8% (n=20) of the insured canceled for financial reasons (p\u3c0.0001). In comparison to the previous study performed by Kaufman and Chavez, the results revealed a 50% decrease in the number of self pay patients failing to receive recommended surgery. Of those self pay patients who did not receive surgery, there was no significant difference in the rate of canceling for financial reasons (p=0.18). Conclusions: Despite gender or race, self-pay patients cancel elective surgeries at a rate significantly greater than insured patients. The more liberal sliding scale down payment policy appears effective in reducing the overall number of self pay patients who decline elective surgery for financial reasons. Self pay patients are still facing financial barriers to health care access despite the sliding scale payment policy

    Maternal Antibody and ASD: Clinical Data and Animal Models

    Over the past several decades there has been an increasing interest in the role of environmental factors in the etiology of neuropsychiatric and neurodevelopmental disorders. Epidemiologic studies have shifted from an exclusive focus on the identification of genetic risk alleles for such disorders to recognizing and understanding the contribution of xenobiotic exposures, infections, and the maternal immune system during the prenatal and early post-natal periods. In this review we discuss the growing literature regarding the effects of maternal brain-reactive antibodies on fetal brain development and their contribution to the development of neuropsychiatric and neurodevelopmental disorders. Autoimmune diseases primarily affect women and are more prevalent in mothers of children with neurodevelopmental disorders. For example, mothers of children with Autism Spectrum Disorder (ASD) are significantly more likely to have an autoimmune disease than women of neurotypically developing children. Moreover, they are four to five times more likely to harbor brain-reactive antibodies than unselected women of childbearing age. Many of these women exhibit no apparent clinical consequence of harboring these antibodies, presumably because the antibodies never access brain tissue. Nevertheless, these maternal brain-reactive antibodies can access the fetal brain, and some may be capable of altering brain development when present during pregnancy. Several animal models have provided evidence that in utero exposure to maternal brain-reactive antibodies can permanently alter brain anatomy and cause persistent behavioral or cognitive phenotypes. Although this evidence supports a contribution of maternal brain-reactive antibodies to neurodevelopmental disorders, an interplay between antibodies, genetics, and other environmental factors is likely to determine the specific neurodevelopmental phenotypes and their severity. Additional modulating factors likely also include the microbiome, sex chromosomes, and gonadal hormones. These interactions may help to explain the sex-bias observed in neurodevelopmental disorders. Studies on this topic provide a unique opportunity to learn how to identify and protect at risk pregnancies while also deciphering critical pathways in neurodevelopment

    Saúde e educação na ditadura de Batista e transformações das políticas cubanas pós-revolução

    Get PDF
    O artigo analisa como as políticas públicas de saúde e educação em Cuba durante a ditadura de Fulgencio Batista Zaldívar (1952/1958) não atenderam as preocupações e necessidades da população. Essa situação gerou, naquele período, o sofrimento por doenças curáveis, mortes prematuras de crianças, analfabetismo e também a falta de participação da sociedade na solução dos problemas. Após a Revolução (a partir de 1959), foram implementadas mudanças significativas para melhorar a saúde e a educação, tais como a campanha de alfabetização e outros programas para garantir o acesso universal e gratuito aos serviços com qualidade que se tornaram direitos fundamentais, com foco no trabalho preventivo e comunitário, e o sistema de educação integral que se tornou referência para outros povos. É importante ressaltar que, após mais de 60 anos de bloqueio econômico dos Estados Unidos, a COVID-19, assim como outros fatores limitantes internos, condicionaram um impacto negativo na vida econômica e social do país, contudo, ao mesmo tempo, estimularam a resistência do país e o desenvolvimento de inovações
