    Cultural Historical Context of Qwu?gwes (Puget Sound, USA): A Preliminary Investigation

    Recent research at the Puget Sound site of Qwu?gwes indicates that it contains a Late Period component of stone, bone-antler and shell artifacts, as well as a waterlogged section containing basketry, cordage and wooden artifacts and associated manufacturing debris. In order to place Qwu?gwes into the culture historical context of the Central Northwest Coast, we have applied cladistic tree-building methods to data derived from these artifacts and from artifacts commonly found in the northern part of Puget Sound, the Gulf of Georgia, the Strait of Juan de Fuca, Washington State, and Vancouver Island. The tree derived from the stone, bone-antler and shell data differs from the trees derived from the basketry data. This suggests that there was a difference in the transmission of information regarding the manufacture and use of the two groups of artifacts. Ideas pertaining to the artifacts made of stone, bone-antler and shell seem to have been shared widely, whereas ideas associated with the artifacts made of basketry were not. There are several possible explanations for this difference, but ethnographic evidence suggests that it is probably primarily a result of the basketry artifacts playing a role in ethnic identity signaling in a way that the stone, bone-antler and shell artifacts did not

    Food Bag Program to Address the Immediate Food Needs of Patients During the COVID-19 Crisis

    The COVID-19 pandemic has heightened food insecurity across the country. In this report we describe creation of a novel emergency department (ED) food bag program in New York City. The food bag program was designed to help meet immediate food needs of patients being discharged from the ED. Each bag contained shelf-stable food as well as a handout describing other community food resources. The program leveraged community-hospital partnerships, was met with enthusiasm from patients and staff alike, and would be highly replicable to other settings.https://deepblue.lib.umich.edu/bitstream/2027.42/156010/1/FINAL_Food bag program article_complete_7.2.20.pdfDescription of FINAL_Food bag program article_complete_7.2.20.pdf : Main Articl

    Ecological insights into abyssal bentho-pelagic fish at 4000 m depth using a multi-beam echosounder on a remotely operated vehicle

    Ecological and behavioral data on mobile, low density, benthopelagic animals is difficult to collect in the abyssal environment. However, these species occupy an important position in the abyssal food chain. At-depth ROV-mounted echosounder studies provide a powerful tool to gather in-situ information on abyssal benthopelagic assemblages and discern their distribution, behavior and habitat associations. This study presents a new perspective on mobile benthopelagic assemblages at the long-term study site, Station M (∼4000 m), using a Seabat T20-S MBES mounted on the ROV Doc Ricketts. The targets (∼45 m off the seafloor) are believed to be the abyssal grenadier of the species Coryphaenoides armatus or C. yaquinae, species known to dominate the mobile benthopelagic fauna at Station M. The swimming behavior of the targets indicated little evidence of avoidance or attraction to the slowly moving ROV and demonstrates the effectiveness of this platform to collect data on benthopelagic fish. The information on targets in close (<1 m) association with the seafloor from the MBES corresponded well to target densities recorded by the video transects. However, in addition the MBES resolved the distribution of targets up to 45 m above the seafloor. Target density had a small peak close to the seafloor (<1 m) but increased in density with height above the seafloor, exceeding the maximum near-bottom density by ∼50 times. ROV-mounted MBES surveys can effectively provide data on the distribution and behavior of benthopelagic fish and further understanding of the pelagic-benthic links in the abyssal deep-sea.acceptedVersio

    Discordant Immune Response with Antiretroviral Therapy in HIV-1: A Systematic Review of Clinical Outcomes.

    BACKGROUND A discordant immune response (DIR) is a failure to satisfactorily increase CD4 counts on ART despite successful virological control. Literature on the clinical effects of DIR has not been systematically evaluated. We aimed to summarise the risk of mortality, AIDS and serious non-AIDS events associated with DIR with a systematic review. METHODS The protocol is registered with the Centre for Review Dissemination, University of York (registration number CRD42014010821). Included studies investigated the effect of DIR on mortality, AIDS, or serious non-AIDS events in cohort studies or cohorts contained in arms of randomised controlled trials for adults aged 16 years or older. DIR was classified as a suboptimal CD4 count (as defined by the study) despite virological suppression following at least 6 months of ART. We systematically searched PubMed, Embase, and the Cochrane Library to December 2015. Risk of bias was assessed using the Cochrane tool for assessing risk of bias in cohort studies. Two authors applied inclusion criteria and one author extracted data. Risk ratios were calculated for each clinical outcome reported. RESULTS Of 20 studies that met the inclusion criteria, 14 different definitions of DIR were used. Risk ratios for mortality in patients with and without DIR ranged between 1.00 (95% CI 0.26 to 3.92) and 4.29 (95% CI 1.96 to 9.38) with the majority of studies reporting a 2 to 3 fold increase in risk. CONCLUSIONS DIR is associated with a marked increase in mortality in most studies but definitions vary widely. We propose a standardised definition to aid the development of management options for DIR

    Renal Tubular Cell-Derived Extracellular Vesicles Accelerate the Recovery of Established Renal Ischemia Reperfusion Injury

    Ischemic renal injury is a complex syndrome; multiple cellular abnormalities cause accelerating cycles of inflammation, cellular damage, and sustained local ischemia. There is no single therapy that effectively resolves the renal damage after ischemia. However, infusions of normal adult rat renal cells have been a successful therapy in several rat renal failure models. The sustained broad renal benefit achieved by relatively few donor cells led to the hypothesis that extracellular vesicles (EV, largely exosomes) derived from these cells are the therapeutic effector in situ We now show that EV from adult rat renal tubular cells significantly improved renal function when administered intravenously 24 and 48 hours after renal ischemia in rats. Additionally, EV treatment significantly improved renal tubular damage, 4-hydroxynanoneal adduct formation, neutrophil infiltration, fibrosis, and microvascular pruning. EV therapy also markedly reduced the large renal transcriptome drift observed after ischemia. These data show the potential utility of EV to limit severe renal ischemic injury after the occurrence
