Childcare And Entrepreneurship: A Business Case Study

The Riverhouse Children’s Center is an actual day care business. The case is an example of a small niche-business common to locales across the United States. Riverhouse is atypical of private day care centers in that it is organized as a not-for-profit institution. The case reviews the benefits and pitfalls of obtaining not-for-profit tax status for a business. The case also presents the different pricing mechanisms embedded in the fee structure of the center. Case discussion questions lead students to suggest a restructuring of the revenue side of the business. Additionally, the case reveals that there may be non-monetary motivations for entrepreneurs and highlights the challenge of working within a tight budget

Lrp12/Mig13a Reveals Changing Patterns of Preplate Neuronal Polarity during Corticogenesis that Are Absent in Reeler Mutant Mice

During corticogenesis, the earliest generated neurons form the preplate, which evolves into the marginal zone and subplate. Lrp12/Mig13a, a mammalian gene related to the Caenorhabditis elegans neuroblast migration gene mig-13, is expressed in a subpopulation of preplate neurons that undergo ventrally directed tangential migrations in the preplate layer and pioneer axon projections to the anterior commissure. As the preplate separates, Lrp12/Mig13a-positive neurons polarize in the radial plane and form a pseudocolumnar pattern, prior to moving to a deeper position within the emerging subplate layer. These changes in neuronal polarity do not occur in reeler mutant mice, revealing the earliest known defect in reeler cortical patterning and suggesting that the alignment of preplate neurons into a pseudolayer facilitates the movement of later-born radially migrating neurons into the emerging cortical plate

Hematopoietic Stem Cell Transplantation Resolves the Immune Deficit Associated with STAT3-Dominant-Negative Hyper-IgE Syndrome.

The quality of life in patients with STAT3-HIES is determined by not only the progressive, life-limiting pulmonary disease, but also significant skin disease including recurrent infections and abscesses requiring surgery. Our early report indicated that hematopoietic stem cell transplantation might not be effective in patients with STAT3-HIES, although a few subsequent reports have reported successful outcomes. We update on progress of our patient now with over 18 years of follow-up and report on an additional seven cases, all of whom have survived despite demonstrating significant disease-related pathology prior to transplant. We conclude that effective cure of the immunological aspects of the disease and stabilization of even severe lung involvement may be achieved by allogeneic hematopoietic stem cell transplantation. Recurrent skin infections and abscesses may be abolished. Donor TH17 cells may produce comparable levels of IL17A to healthy controls. The future challenge will be to determine which patients should best be offered this treatment and at what point in their disease history.Job Research Foundation Welsh Clinical Academic Training (WCAT) programme German Research Foundation (DFG) German Research Foundation (DFG) Federal Ministry of Education & Research (BMBF) Center for Chronic Immunodeficiency (CCI), Freiburg Center for Rare Diseases (FZSE

TRY plant trait database – enhanced coverage and open access

Plant traits - the morphological, anatomical, physiological, biochemical and phenological characteristics of plants - determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait‐based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits - almost complete coverage for ‘plant growth form’. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait–environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Optimization of RNA-based transgene expression by targeting Protein Kinase R

The aim of this thesis was to establish a method for repeated transfection of in vitro transcribed RNA (IVT-RNA) leading to a sustained protein expression lasting for days or even weeks. Once transfected cells recognize IVT-RNA as "non-self" and initiate defense pathways leading to an upregulated interferon (IFN) response and stalled translation. In this work Protein Kinase R (PKR) was identified as the main effector molecule mediating this cellular response. We assessed four strategies to inhibit PKR and the IFN response: A small molecule PKR inhibitor enhanced protein expression and hampered the induction of IFN-transcripts, but had to be excluded due to cytotoxicity. A siRNA mediated PKR knockdown and the overexpression of a kinase inactive PKR mutant elevated the protein expression, but the down-regulation of the IFN response was insufficient. The co-transfer of the viral inhibitors of PKR and the IFN response was most successful. The use of E3, K3 and B18R co-transfection enabled repeated IVT-RNA-based transfection of human fibroblasts. Thus, the developed protocol allows a continuous IVT-RNA encoded protein expression of proteins, which could be the basis for the generation of induced pluripotent stem cells (iPS) for several therapeutic applications in regenerative medicine or drug research.Das Ziel dieser Arbeit bestand in der Etablierung einer Methode, welche eine wiederholte Transfektion mit in vitro transkribierter RNA (IVT-RNA) ermöglicht und zu einer mehrtägigen Proteinexpression beiträgt. Nach einer Transfektion erkennen die Zellen IVT-RNA als "nicht-selbst" und induzieren zelluläre Abwehrmechanismen, welche durch die Interferonantwort (IFN) vermittelt und von einer Herunterregulation der Translation begleitet sind. Die Protein Kinase R (PKR) besitzt eine wichtige Rolle in der Signaltransduktion, weshalb mittels vier Strategien eine Inhibition der PKR sowie der IFN Antwort verfolgt wurde. Ein niedermolekularer PKR Inhibitor steigerte die Proteinexpression und reduzierte die Interferonantwort, musste aber wegen Zytotoxizität ausgeschlossen werden. Sowohl durch siRNA vermittelte Herunterregulation der PKR, als auch durch die Überexpression einer Kinase inaktiven PKR Mutante konnte die Proteinexpression verbessert werden. Die Interferonantwort konnte jedoch nicht ausreichend reduziert werden. Der Co-Transfer von viralen Inhibitoren von PKR und Interferonantwort war am erfolgreichsten. Die Co-Transfektion von E3, K3 und B18R erlaubte repetitive IVT-RNA-basierte Transfektionen von humanen Fibroblasten. Somit kann das entwickelte Protokoll zur kontiuierlichen Expression von IVT-RNA kodierter Proteine verwendet werden, welches z.B. als Grundlage für die Herstellung von induzierten pluripotenten Zellen (iPS) dienen kann. Aber auch therapeutische Anwendungen, die regenerative Medizin sowie die Wirkstoffforschung könnten von diesem Protokoll profitieren

Incremental efficacy of adding bupropion to the nicotine patch for smoking cessation in smokers with a recent history of alcohol dependence: results from a randomized, double-blind, placebo-controlled study

AIMS: The primary aim of this study was to compare the efficacy of smoking cessation treatment using a combination of nicotine patch and bupropion vs. nicotine patch and placebo bupropion. A secondary aim was to investigate whether the efficacy of bupropion is moderated by belief about whether one is receiving active or placebo medication. METHODS: Participants were recruited from a residential substance abuse treatment program and the community. We randomly assigned 148 smokers with between 2 and 12 months of alcohol abstinence to nicotine patch plus bupropion or nicotine patch plus placebo. All participants also received seven counseling sessions. RESULTS: At follow up, differences between medication conditions were not significant. Seven-day point prevalence quit rates in the patch plus bupropion vs. patch plus placebo conditions at week 24 were 6% and 11%, respectively. Differences between groups on prolonged abstinence and time to first smoking lapse were also not significant. However, among participants who received bupropion, those who accurately guessed that they were receiving bupropion were more likely to remain abstinent than those who incorrectly believed they were receiving placebo. CONCLUSIONS: Findings do not support combining nicotine patch and bupropion for smoking cessation in this population. However, findings support previous studies suggesting the importance of assessing the blind in smoking cessation studies and its possible moderating effect on medication efficacy. Future directions for enhancing smoking cessation outcome in these smokers include investigations of intensive behavioral and pharmacological interventions, including studies of potential interactions between individual genetic differences and medication efficacy
