The sinking properties of three strains of Emiliania huxleyi in response to temperature changes were examined. We used a recently proposed approach to calculate sinking velocities from coccosphere architecture, which has the advantage to be applicable not only to culture samples, but also to field samples including fossil material. Our data show that temperature in the sub-optimal range impacts sinking velocity of E. huxleyi. This response is widespread among strains isolated in different locations and moreover comparatively predictable, as indicated by the similar slopes of the linear regressions...

Minority stress theory has widespread research support in explaining health disparities experienced by sexual and gender minorities. However, less is known about how minority stress impacts multiply marginalized groups, such as lesbian, gay, bisexual, and transgender people of color (LGBT POC). Also, although research has documented resilience in the face of minority stress at the individual level, research is needed that examines macro-level processes such as community resilience (Meyer, 2015). In the current study, we integrate minority stress theory and intersectionality theory to examine multiple minority stress (i...

BACKGROUND: Calculation of cardiovascular magnetic resonance (CMR) extracellular volume (ECV) requires input of hematocrit, which may not be readily available. The purpose of this study was to evaluate the diagnostic accuracy of ECV calculated using various noninvasive measures of hematocrit compared to ECV calculated with input of laboratory hematocrit as the reference standard. METHODS: One hundred twenty three subjects (47.7 ± 14.1 years; 42% male) were prospectively recruited for CMR T1 mapping between August 2016 and April 2017...

Time-of-flight (TOF) magnetic sensing of rolling immunomagnetically-labeled cells offers great potential for single cell function analysis at the bedside in even optically opaque media, such as whole blood. However, due to the spatial resolution of the sensor and the low flow rate regime required to observe the behavior of rolling cells, the concentration range of such a workflow is limited. Potential clinical applications, such as testing of leukocyte function, require a cytometer which can cover a cell concentration range of several orders of magnitude...

This work aims to face the challenge of monitoring small molecule drugs accurately and rapidly for point-of-care (POC) diagnosis in current clinical settings. Overdose of acetaminophen (AP), a commonly used OTC analgesic drug, has been determined to be a major cause of acute liver failure in the US and the UK. However, there is no rapid and accurate detection method available for this drug in the emergency room. The present study examined an AP sensing strategy that relies on a previously unexplored strong interaction between AP and the arginine (Arg) molecule...

BACKGROUND: Hyperglycemia is a common adverse event associated with parenteral nutrition (PN); however, there is no consensus on optimal glucose monitoring. Unnecessary point-of-care (POC) blood glucose (BG) testing can result in additional healthcare cost and discomfort to the patient. This study's aim was to determine whether decreasing the frequency of POC glucose testing in patients receiving PN can reduce costs without increasing the frequency of glycemic events. METHODS: This study examined adult, noncritically ill patients who require PN and are managed by a nutrition support team...

Schistosomiasis is still a public health problem in Brazil. The Kato-Katz test is the most frequently used diagnostic method for Schistosoma mansoni infection. However, it lacks sensitivity in areas of low prevalence. We have assessed the positivity rate of S. mansoni infection in Bananeiras, a village on Capistrano, Ceara, Brazil by performing a point-of-care test in urine to determine the circulating cathodic antigens (POC-CCA), and we compared the findings with those of the Kato-Katz technique for egg detection in stool and an enzyme-linked immunosorbent assay for specific antibodies against adult worms (SWAP-ELISA) in serum before treatment (baseline)...

Transparent Exopolymer Particles (TEPs) are a subclass of organic particles with high impact in biogeochemical and ecological processes, such as the biological carbon pump, air-sea interactions, or the microbial loop. However, the complexity in production and consumption makes TEP dynamics hardly predictable, calling for the need of descriptive studies about the in situ dynamics of these particles. We followed monthly TEP dynamics and combined them with a dataset of environmental variables during three years in a coastal site of the oligotrophic North Western Mediterranean (Blanes Bay)...

BACKGROUND: A reliable population screening strategy for hepatitis C virus (HCV) infection may be based in easy-to-use point-of-care (POC) tests for HCV antibodies, but validation data is needed before their potential widespread use in primary care or outreach practice. Besides, the sensitivity of these POC tests in patients with spontaneous or treatment-induced viral clearance is unknown. OBJECTIVES: To test the performance of a non-invasive POC anti-HCV test (OraQuick HCV rapid test) in oral mucosal transudate (OMT) and fingerstick blood from patients with known anti-HCV serostatus and with or without active viremia (after treatment-induced clearance)...

Background: Prior to eliminating schistosomiasis, efforts must address accurate and fast individual diagnosis. Diagnosis is still inaccurate by parasitological and point-of-care circulating cathodic antigen (POC-CCA) in areas of low endemicity. Methods: Our group has optimized POC-CCA with a 30 min urine concentration step with no need for specialized technicians or equipment and with high accuracy. We evaluated this new method, called POC-CCA filter (FLT), in two Brazilian endemic areas with distinct profiles...

In this study, a poly (octanediol citrate) (POC)/bioglass nanofiber composite was prepared by incorporating electrospun bioglass nanofiber (5, 10, and 15% w/w) into the POC matrix. The bioglass nanofiber interacted with POC via physical adsorption and carboxylate formation, and thus the addition of bioglass nanofiber increased the glass transition temperature, modulus and strength; however, decreased the elongation at break when the amount of bioglass nanofiber was up to 15% w/w. Compared to the pure POC elastomer, the POC/bioglass nanofiber composites exhibited accelerated stimulation to the mouse bone marrow mesenchymal stem cells (MSCs) on the cell growth and osteogenic differentiation...

BACKGROUND: Hepatitis E virus (HEV)-caused acute viral hepatitis is a major threat to public health worldwide. Recently, an enzyme linked immunosorbent assay (ELISA) kit detecting the HEV antigen was reported to have good concordance with the HEV RNA load and showed good clinical performance. But the ELISA kits can barely satisfy the needs of community clinics. In this study, a fluorescent microbead-based immunoassay (FMIA) for detecting the HEV antigen was developed and evaluated. METHODS: A mouse anti-HEV monoclonal antibody (mAb) conjugated with fluorescent microbeads was used as capturing antibody and another mouse mAb was used as detection antibody...

Control initiatives have successfully reduced the prevalence and intensity of schistosomiasis transmission in several localities around the world. However, individuals that release low numbers of eggs in their feces may not be detected by classical methods that are limited by low sensitivity. Given that accurate estimates of prevalence are key to implementing planning control actions for the elimination of schistosomiasis, new diagnostic tools are needed to effectively monitor infections and confirm transmission interruption...

Influenza has been a long-running health problem and novel antiviral drugs are urgently needed. In pre-clinical studies, we demonstrated broad antiviral activity of D, L-lysine-acetylsalicylate glycine (LASAG) against influenza virus (IV) in cell culture and protection against lethal challenge in mice. LASAG is a compound with a new antiviral mode of action. It inhibits the NF-κB signal transduction module that is essential for IV replication. Our goal was to determine whether aerosolized LASAG would also show a therapeutic benefit in hospitalized patients suffering from severe influenza...

The Centers for Disease Control and Prevention (CDC) and many public health jurisdictions continue to advocate for the most sensitive rapid HIV test that is available. Currently, the recommendation is to utilize tests that can detect HIV infection biomarkers within 30 days of infection, when initial immune responses are mounted. The infected patient's IgM response is often used to detect acute infection within a 20-25 days window after infection. This requirement applies to lab-based testing with automated analyzers and rapid, point of care (POC) testing used for screening in a non-clinical setting...
