    Skin-to-skin contact can reduce neonatal mortality or morbidity by 18-42%. After birth temperature regulation is essential in newborn babies. Skin-to-skin benefits include: regulating heart rate, temperature, and respirations; greater weight gain. The purpose of this study is to determine if skin-to-skin care is more efficient in stabilizing the temperature of a full-term infant than using a radiant warmer. If so, why are radiant warmers still used on health full-term infants if skin-to-skin has more benefits

    Early disruption of photoreceptor cell architecture and loss of vision in a humanized pig model of usher syndromes

    Usher syndrome (USH) is the most common form of monogenic deaf-blindness. Loss of vision is untreatable and there are no suitable animal models for testing therapeutic strategies of the ocular constituent of USH, so far. By introducing a human mutation into the harmonin-encoding USH1C gene in pigs, we generated the first translational animal model for USH type 1 with characteristic hearing defect, vestibular dysfunction, and visual impairment. Changes in photoreceptor architecture, quantitative motion analysis, and electroretinography were characteristics of the reduced retinal virtue in USH1C pigs. Fibroblasts from USH1C pigs or USH1C patients showed significantly elongated primary cilia, confirming USH as a true and general ciliopathy. Primary cells also proved their capacity for assessing the therapeutic potential of CRISPR/Cas-mediated gene repair or gene therapy in vitro. AAV-based delivery of harmonin into the eye of USH1C pigs indicated therapeutic efficacy in vivo

    Understanding the seasonal and reproductive biology of olive fruit fly is critical to its management

    Full text link
    The olive fruit fly was first detected in Los Angeles in 1998 and in all the olive-growing regions of California soon after. Following its initial detection, UC researchers and Cooperative Extension farm advisors, county agricultural commissioners and the California Department of Food and Agriculture Pest Detection and Emergency Project established a statewide monitoring program to determine the extent of the olive fruit fly’s occurrence, track its seasonal biology and evaluate monitoring tools. Fly populations and infestations can reach high levels throughout California but tend to be lower in the San Joaquin Valley. Trap captures typically exhibit a bimodal distribution with peaks in the spring and fall. Olive infestation is related to fly densities, climate and fruit size. Gravid, mated females vary in density throughout the year but are present at some level year-round. The data is being used to develop models that will better predict when the adults are active and olives are at risk

    An endemic genus of Madagascan spiders (Araneae, Archaeidae, Eriauchenius) is revised. All 20 species of Eriauchenius are described and keyed, of which 14 are new species: Eriauchenius andriamanelo sp. n., Eriauchenius andrianampoinimerina sp. n., Eriauchenius goodmani sp. n., Eriauchenius harveyi sp. n., Eriauchenius lukemacaulayi sp. n., Eriauchenius milajaneae sp. n., Eriauchenius milloti sp. n., Eriauchenius rafohy sp. n., Eriauchenius ranavalona sp. n., Eriauchenius rangita sp. n., Eriauchenius rixi sp. n., Eriauchenius sama sp. n., Eriauchenius wunderlichi sp. n., Eriauchenius zirafy sp. n. Additionally, six species of the new genus Madagascarchaea gen. n. are described and keyed, of which four are new species: Madagascarchaea fohy sp. n., Madagascarchaea lotzi sp. n., Madagascarchaea moramora sp. n., Madagascarchaea rabesahala sp. n. Diagnostic characters for the Madagascan and African genera are described, and based on these characters and previous phylogenetic analyses the following species transfers are proposed: Eriauchenius cornutus (Lotz, 2003) to Afrarchaea; Afrarchaea fisheri (Lotz, 2003) and Afrarchaea mahariraensis (Lotz, 2003) to Eriauchenius. Finally, we propose that the distribution of Afrarchaea be restricted to South Africa. While several Madagascan specimens have previously been identified as Afrarchaea godfreyi (Hewitt, 1919), we argue that these are likely misidentifications that should instead be Eriauchenius

    Generation of an induced pluripotent stem cell line, ZIPi021-A, from fibroblasts of a Prader-Willi syndrome patient with maternal uniparental disomy (mUPD)

    No full text
    Prader-Willi syndrome (PWS) is a neurodevelopmental disorder caused by loss of paternal expression of imprinted genes on chromosome 15q11-q13. We established a human induced pluripotent stem cell line (hiPSC), ZIPi021-A, from fibroblasts of a 4-year-old female PWS patient with the subtype of maternal uniparental disomy (mUPD). The generated hiPSC line was transgene-free, expressed pluripotency markers and showed the ability to differentiate into all three germ layers in vitro. The ZIPi021-A hiPSC line could be used as a cellular model for PWS in humans

    Roadmap on nanomedicine for the central nervous system

    In recent years, a great deal of effort has been undertaken with regards to treatment of pathologies at the level of the central nervous system (CNS). Here, the presence of the blood-brain barrier acts as an obstacle to the delivery of potentially effective drugs and makes accessibility to, and treatment of, the CNS one of the most significant challenges in medicine. In this Roadmap article, we present the status of the timeliest developments in the field, and identify the outstanding challenges and opportunities that exist. The format of the Roadmap, whereby experts in each discipline share their viewpoint and present their vision, reflects the dynamic and multidisciplinary nature of this research area, and is intended to generate dialogue and collaboration across traditional subject areas. It is stressed here that this article is not intended to act as a comprehensive review article, but rather an up-to-date and forward-looking summary of research methodologies pertaining to the treatment of pathologies at the level of the CNS

    Intracranial Rescue Stent Angioplasty After Stent-Retriever Thrombectomy Multicenter Experience

    Purpose Stent-retriever thrombectomy (SRT) for acute intracranial large artery occlusion (LAO) may not result in permanent recanalization in rare cases, e.g. due to an underlying stenosis or dissection. In this specific patient group, rescue stent angioplasty (RSA) may be the only treatment option to achieve permanent vessel patency and potentially a good clinical outcome. To date, the experience with RSA is limited. Methods In this retrospective analysis, interventional and clinical data of patients with acute intracranial LAO of the anterior and posterior circulation who underwent RSA after SRT due to an underlying lesion between 2012-2017 in four neurovascular centers were studied. Results In this study 34 patients (mean age 67 years) were included whereby 18 patients had anterior circulation LAO and 16 patients posterior circulation LAO. The SRT maneuver count ranged between 1 and 15 (median 2). Indications for RSA were an immediate re-occlusion in 25 (74%), and a persistent high-grade stenosis in 9 patients (26%). The RSA was technically feasible in 33 patients (97%). A mTICI 2b/3 result was obtained in 26 patients (76%). Median onset-to-recanalization time was 248min (range 80-650min). After 3 months 10/34 patients (29%) had a good clinical outcome (modified Rankin Scale, mRS 0-2). In detail, 4/18 patients (22%) with anterior circulation LAO and 6/16 patients (38%) with posterior circulation LAO were functionally independent. Conclusion The use of RSA can be considered for acute intracranial LAO in cases with immediate re-occlusion or high-grade stenosis after SRT alone
