    According to the Census Bureau, American society is experiencing a cultural shift in living trends: city living is slowly replacing its suburban counterpart. As a result, there is a growing need for cities to accommodate people of all demographics. Currently, the western-most part of Chelsea located on the lower west side of Manhattan is failing to do this. Since the mid 1990s Chelsea has been a major center of the New York art world; serving as home to hundreds of local art galleries and studios. With the opening of the High Line in 2006 (a successful adaptive re-use project of former rail lines originally built in the 1880s), West Chelsea has experienced an influx of people interested in living in the district. Currently, expensive luxury housing, loft spaces, and converted luxury apartments dominate the West Chelsea housing market. This dearth of housing options has greatly limited people from varying social, cultural and economic backgrounds and circumstances from moving into West Chelsea. This thesis imagines an apartment complex in West Chelsea that offers a variety of compact housing types while fostering a sense of community in order to bring families, singles, and people of all ages, to the vibrant arts community of West Chelsea

    A simplified mixture of model stratum corneum lipids was mixed with different surfactants to make a preliminary estimation of the influence of surfactants on the stratum corneum lipid structure. The results revealed differences between cationic and anionic surfactants and between anionic surfactants with different structures. © 1998

    Full Count of Eviction Cases Filed in Oregon Available for the First Time

    Get PDF
    Residential eviction cases can be filed in two court types in Oregon, circuit courts and justice courts. Up until now, statewide research on evictions has only included filings in circuit courts, because those court records are accessible through a centralized online database run by the judicial department. Eviction cases can be filed in fourteen justice courts in Oregon. Because each justice court maintains their court’s records onsite, these eviction cases have previously been invisible to researchers and policymakers. This study reports the first-ever full accounting of the number of eviction cases filed in Oregon, including cases filed in both court systems

    Severe storms such as Hurricane Harvey that battered the Texas Gulf Coast in August 2017 not only stretch resources related to short-term rescue, safety and health, but also generate extensive discussion and planning to manage the long-term recovery as well as to improve the resilience of Texas Coastal communities. Any future planning, policies, and resource allocation strategies will reflect key local and state stakeholders’ views regarding risk, cost, capacity, and policy options (see, for example, Alexander, 2000; Adger et al. 2005; Comfort, Boin and Demchak, 2010; Portney, 2015; and Wenger, 2017). The project team designed and deployed a targeted in-depth survey of key stakeholders in the Texas Coastal Bend Region to identify their views on problem sources, risk perceptions, planning goals, policy evaluations, resource allocations, and patterns of interaction across groups related to recent environmental stressors like Harvey. The findings from this survey are reported below.This material is based upon research supported by the Texas OneGulf RESTORE Center of Excellence Hurricane Harvey Decision-Support – Resilient Environments and Communities under award 1 RCEGR480001-01-00. Federal funding from the US Department of Treasury through the State of Texas under the Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act of 2012

    Loss of interleukin (IL)-7 or the IL-7 receptor alpha (IL-7Rα, CD127) results in severe immunodeficiencies in mice and humans. To more precisely identify signals governing IL-7 function in vivo, we have disrupted the IL-7Rα Y449XXM motif in mice by knock-in mutagenesis (IL-7Rα449F). Thymic precursors were reduced in number in IL-7Rα449F mice, but in marked contrast to IL-7Rα−/− knockout mice, thymocytes and peripheral T cells developed normally. Strikingly, Listeria infection revealed that CD4 and CD8 T cells had different requirements for IL-7Rα signals. CD4 T cells failed to mount a primary response, but despite normal CD8 primary responses, maintenance of CD8 memory was impaired in IL-7Rα449F mice. Furthermore, we show that Bcl-2 is IL-7Rα Y449 independent and insufficient for IL-7–mediated maintenance of CD8 memory

    Safety of celecoxib and nonselective nonsteroidal anti-inflammatory drugs in juvenile idiopathic arthritis: results of the phase 4 registry

    Background This study aimed to assess long-term safety and developmental data on juvenile idiopathic arthritis (JIA) patients treated in routine clinical practice with celecoxib or nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs). Methods Children aged ≥2 to \u3c18 years with rheumatoid-factor–positive or –negative polyarthritis, persistent or extended oligoarthritis, or systemic arthritis were enrolled into this prospective, observational, multicenter standard-of-care registry. Eligible patients were newly or recently prescribed (≤6 months) an nsNSAID or celecoxib. Enrolled patients were followed to the end of the study, whether they remained on the original NSAID, switched, or discontinued therapy altogether. All adverse events (AEs) regardless of severity were captured in the database. Results A total of 274 patients (nsNSAID, n = 219; celecoxib, n = 55) were observed for 410 patient-years of observation. Naproxen, meloxicam, and nabumetone were the most frequently used nsNSAIDs. At baseline, the celecoxib group was older, had a numerically longer median time since diagnosis, and a numerically higher proportion of patients with a history of gastrointestinal-related NSAID intolerance. AEs reported were those frequently observed with NSAID treatment and were similar across groups (nsNSAIDs: 52.0%; celecoxib: 52.9%). Twelve unique patients experienced a total of 18 serious AEs; the most frequent were infections, and none was attributed to NSAID use. Conclusions The safety profile of celecoxib and nsNSAIDs appears similar overall. The results from this registry, ongoing pharmacovigilance, and the phase 3 trial that led to the approval of celecoxib for children with JIA provide evidence that the benefit-risk for celecoxib treatment in JIA remains positive

    Multiplex ligation-dependent probe amplification for genetic screening in autism spectrum disorders: Efficient identification of known microduplications and identification of a novel microduplication in ASMT

    <p>Abstract</p> <p>Background</p> <p>It has previously been shown that specific microdeletions and microduplications, many of which also associated with cognitive impairment (CI), can present with autism spectrum disorders (ASDs). Multiplex ligation-dependent probe amplification (MLPA) represents an efficient method to screen for such recurrent microdeletions and microduplications.</p> <p>Methods</p> <p>In the current study, a total of 279 unrelated subjects ascertained for ASDs were screened for genomic disorders associated with CI using MLPA. Fluorescence in situ hybridization (FISH), quantitative polymerase chain reaction (Q-PCR) and/or direct DNA sequencing were used to validate potential microdeletions and microduplications. Methylation-sensitive MLPA was used to characterize individuals with duplications in the Prader-Willi/Angelman (PWA) region.</p> <p>Results</p> <p>MLPA showed two subjects with typical ASD-associated interstitial duplications of the 15q11-q13 PWA region of maternal origin. Two additional subjects showed smaller, <it>de novo </it>duplications of the PWA region that had not been previously characterized. Genes in these two novel duplications include <it>GABRB3 </it>and <it>ATP10A </it>in one case, and <it>MKRN3</it>, <it>MAGEL2 </it>and <it>NDN </it>in the other. In addition, two subjects showed duplications of the 22q11/DiGeorge syndrome region. One individual was found to carry a 12 kb deletion in one copy of the <it>ASPA </it>gene on 17p13, which when mutated in both alleles leads to Canavan disease. Two subjects showed partial duplication of the <it>TM4SF2 </it>gene on Xp11.4, previously implicated in X-linked non-specific mental retardation, but in our subsequent analyses such variants were also found in controls. A partial duplication in the <it>ASMT </it>gene, located in the pseudoautosomal region 1 (PAR1) of the sex chromosomes and previously suggested to be involved in ASD susceptibility, was observed in 6–7% of the cases but in only 2% of controls (P = 0.003).</p> <p>Conclusion</p> <p>MLPA proves to be an efficient method to screen for chromosomal abnormalities. We identified duplications in 15q11-q13 and in 22q11, including new <it>de novo </it>small duplications, as likely contributing to ASD in the current sample by increasing liability and/or exacerbating symptoms. Our data indicate that duplications in <it>TM4SF2</it> are not associated with the phenotype given their presence in controls. The results in PAR1/PAR2 are the first large-scale studies of gene dosage in these regions, and the findings at the <it>ASMT </it>locus indicate that further studies of the duplication of the <it>ASMT </it>gene are needed in order to gain insight into its potential involvement in ASD. Our studies also identify some limitations of MLPA, where single base changes in probe binding sequences alter results. In summary, our studies indicate that MLPA, with a focus on accepted medical genetic conditions, may be an inexpensive method for detection of microdeletions and microduplications in ASD patients for purposes of genetic counselling if MLPA-identified deletions are validated by additional methods.</p

    This work is licensed under a Creative Commons Attribution 4.0 Unported License.Far-infrared astronomy has advanced rapidly since its inception in the late 1950s, driven by a maturing technology base and an expanding community of researchers. This advancement has shown that observations at far-infrared wavelengths are important in nearly all areas of astrophysics, from the search for habitable planets and the origin of life to the earliest stages of galaxy assembly in the first few hundred million years of cosmic history. The combination of a still-developing portfolio of technologies, particularly in the field of detectors, and a widening ensemble of platforms within which these technologies can be deployed, means that far-infrared astronomy holds the potential for paradigm-shifting advances over the next decade. We examine the current and future far-infrared observing platforms, including ground-based, suborbital, and space-based facilities, and discuss the technology development pathways that will enable and enhance these platforms to best address the challenges facing far-infrared astronomy in the 21st century
