    An institutional view of local entrepreneurial climate

    This paper proposes a conceptual framework on the role of formal and informal institutional factors at the sub-national level (e.g. city) in shaping the climate conducive for the growth and success of micro, small, and medium enterprises (MSMEs). Extant literature reveals that institutional analyses tend to focus on either formal or informal institutions, in narrow and fragmented ways. Likewise, previous studies focused their analysis on national or country-wide institutional frameworks, ignoring the institutional heterogeneity of regions and cities within a given country. This study attempts to develop an integrated institutional approach at the city-level and stretch the conceptual boundaries of formal and informal institutions as they shape the local entrepreneurial climate &ndash; the set of tangible and intangible institutional factors that are shaping the performance of entrepreneurial firms in a geographically and politically defined area such as a city.<br /

    Regulation of Adipocyte 11ÎČ-Hydroxysteroid Dehydrogenase Type 1 (11ÎČ-HSD1) by CCAAT/Enhancer-Binding Protein (C/EBP) ÎČ Isoforms, LIP and LAP

    11ÎČ-hydroxysteroid dehydrogenase type 1 (11ÎČ-HSD1) catalyses intracellular regeneration of active glucocorticoids, notably in liver and adipose tissue. 11ÎČ-HSD1 is increased selectively in adipose tissue in human obesity, a change implicated in the pathogenesis of metabolic syndrome. With high fat (HF)-feeding, adipose tissue 11ÎČ-HSD1 is down-regulated in mice, plausibly to counteract metabolic disease. Transcription of 11ÎČ-HSD1 is directly regulated by members of the CCAAT/enhancer binding protein (C/EBP) family. Here we show that while total C/EBPÎČ in adipose tissue is unaltered by HF diet, the ratio of the C/EBPÎČ isoforms liver-enriched inhibitor protein (LIP) and liver-enriched activator protein (LAP) (C/EBPÎČ-LIP:LAP) is increased in subcutaneous adipose. This may cause changes in 11ÎČ-HSD1 expression since genetically modified C/EBPÎČ(+/L) mice, with increased C/EBPÎČ-LIP:LAP ratio, have decreased subcutaneous adipose 11ÎČ-HSD1 mRNA levels, whereas C/EBPÎČΔuORF mice, with decreased C/EBPÎČ-LIP:LAP ratio, show increased subcutaneous adipose 11ÎČ-HSD1. C/EBPÎČ-LIP:LAP ratio is regulated by endoplasmic reticulum (ER) stress and mTOR signalling, both of which are altered in obesity. In 3T3-L1 adipocytes, 11ÎČ-HSD1 mRNA levels were down-regulated following induction of ER stress by tunicamycin but were up-regulated following inhibition of mTOR by rapamycin. These data point to a central role for C/EBPÎČ and its processing to LIP and LAP in transcriptional regulation of 11ÎČ-HSD1 in adipose tissue. Down-regulation of 11ÎČ-HSD1 by increased C/EBPÎČ-LIP:LAP in adipocytes may be part of a nutrient-sensing mechanism counteracting nutritional stress generated by HF diet

    Finishing the euchromatic sequence of the human genome

    The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∌99% of the euchromatic genome and is accurate to an error rate of ∌1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

    Global urban environmental change drives adaptation in white clover

    Get PDF
    Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale

    Implementation of Cognitive Testing via Video-Telemedicine

    No full text
    Background: Early diagnosis and timely follow-up of cognitive decline are essential to preserve individual function and memory, improve quality of life, and decrease healthcare costs. Many barriers to in-person assessment exist, the most recent one being COVID-19. Video-telemedicine has been studied as a solution with promising results. Most notably, research shows that the Mini Mental State Examination (MMSE) administered via video-telemedicine has comparable results to in-person assessment. Purpose: The purpose of this project was to implement cognitive testing via video-telemedicine for follow-up management of cognitive impairment and dementia. Methods: A protocol for conducting the MMSE via Zoom was developed. Next, an E-learning module was created to provide education on the new protocol to increase successful use. The protocol and E-learning were sent to 10 providers and 11 nurse practitioner students. Lastly, a survey was administered to measure participants’ confidence and comfort with the protocol and perceived usefulness of the protocol. Results: Thirteen out of 21 participants completed the survey. Average scores for overall confidence per question ranged from 83-96% confident. Open ended questions showed that 84% of participants felt comfortable using the protocol and 92% found the protocol useful. Conclusion: This project created a standardized, evidence-based way for providers to perform follow up visits of patients with cognitive decline when barriers to in-person assessment exist. Implementation of this project allows for continuity of care and timely intervention in these individuals, which benefits patients and caregivers, and has the potential to decrease healthcare costs
