We examined the effets of changes in hydrostatic pressures on the ultrastructural geometry of the lateral intercellular space and tight junctions in proximal tubules of contrtol (C) and volume-expanded (VE) Necturus kidney. The following groups of tubules were studied: (1) C, free-flow pressure, (2) C, stopped-flow, high-luminal pressure, (3) C, stopped-flow, low-luminal pressure, (4) VE, free-...
The water budget in clay shale terrain is controlled by a complex interaction between the vertisol soil layer, the underlying fractured rock, land use, topography, and seasonal trends in rainfall and evapotranspiration. Rainfall, runoff, lateral flow, soil moisture, and groundwater levels were monitored over an annual recharge cycle. Four phases of soil–aquifer response were noted over the stud...
Optical coherence tomography (OCT) and optical coherence microscopy (OCM) allow the acquisition of quantitative three-dimensional axial flow by estimating the Doppler shift caused by moving scatterers. Measuring the velocity of red blood cells is currently the principal application of these methods. In many biological tissues, blood flow is often perpendicular to the optical axis, creating the ...
Cannabis sativa L. is one of the most consumed drugs in world and recent studies have associated its use with an increase number traffic accidents different countries. In many countries, like Brazil, simple reliable methodologies are still needed for detection on site, mainly cannabinoids, considering prevalence oral fluid (OF) has been proved as appropriate biological matrix this purpose. Cons...
In this work, we investigate the behavior of dilute and semidilute polymer solutions flowing in a microfluidic flow focusing device, in which an inlet stream is stretched by two balanced lateral streams. By varying the flow rates in the inlet and lateral channels and their ratio, several types of flow transitions are observed and the resulting velocity fields are analyzed both upstream and down...
El objetivo de este estudio fue conocer la prevalencia infección por SARS-CoV-2 en pacientes y profesionales un hospital media larga estancia el periodo del pico pandemia España primavera 2020. A finales febrero 2020, se diseñó una estrategia para diagnóstico consistente complementar realización PCR a tiempo real con técnica rápida inmunocromatografía flujo lateral detección anticuerpos IgG e I...
This paper demonstrates a photoacoustics-based lateral flow test that takes advantage of the strong interaction of light and gold nanoparticles to quantitatively detect a disease biomarker. For a commercially available lateral flow test strip, the photoacoustic analysis improved the detection limit by two orders of magnitude compared to colorimetric measurements.
Immunodetection of methicillin-resistant Staphylococcus aureus (MRSA) by conventional methods employing mammalian immunoglobulins has unknown detection limits, and often yields false-positive results because of the presence of S. aureus protein A, which binds the Fc region of mammalian IgG. In this study, a new PBP2a-specific chicken IgY antibody was developed in inbred and conventional chicken...
The recent Zika virus (ZIKV) outbreak demonstrates that cost-effective clinical diagnostics are urgently needed to detect and distinguish viral infections to improve patient care. Unlike dengue virus (DENV), ZIKV infections during pregnancy correlate with severe birth defects, including microcephaly and neurological disorders. Because ZIKV and DENV are related flaviviruses, their homologous pro...
The rapidSTRIPE H1N1 test, based on a nucleic acid lateral-flow assay, has been developed for diagnosis of a swine-origin influenza A (H1N1) virus. This test is simple and cost-effective and allows specific detection of the S-OIV A (H1N1) virus from swab sampling to final detection on a lateral-flow stripe within 2 to 3 h.
