An extensive study to compare planar and single photon emission computed tomographic (SPECT) 99Tcm-dimercaptosuccinic acid (DMSA) determination of differential kidney function (DKF) has been carried out. The study has demonstrated that it is possible to use SPECT differential kidney function in place of that obtained using planar scintigraphy. The SPECT DKF value correlated with the planar DKF value. Gradient shaded three-dimensional surface images, reoriented transaxial, sagittal and coronal slices were produced during the same processing method.

Temperature-Dependent Rotation of Protonated Methyl Groups in Otherwise Deuterated Proteins Modulates DEER Distance Distributions.
Appl Magn Reson
October 2024
Laboratory of Chemical Physics, National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892-0520 USA.
Unlabelled: Temperature-dependent DEER effects are observed as a function of methyl rotation by either leucine- or nitroxide-specific protonated methyl groups in an otherwise deuterated background. Both species induce a site-specific enhancement in the apparent relaxation of the paramagnetic nitroxide label. The presence of a single protonated methyl group in close proximity (4-10 Å) to only one of the two nitroxide rotamer ensembles in AviTagged immunoglobulin-binding B domain of protein A results in a selective and substantial decrease in , manifested by differential decay of the peak intensities in the bimodal distance distribution as a function of the total dipolar evolution time, temperature, or both.

Background: Pregnancy-associated atypical hemolytic uremic syndrome (aHUS) is a form of thrombotic microangiopathy (TMA) caused by uncontrolled activation of the complement system during pregnancy or the postpartum period. In the intensive care unit, aHUS must be differentiated from sepsis-related multiple organ dysfunction, thrombotic thrombocytopenic purpura (TTP), hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. Early recognition of aHUS is critical for effective treatment and improved prognosis.

The delicate balance between bone formation by osteoblasts and bone resorption by osteoclasts maintains bone homeostasis. Nuclear receptors (NRs) are now understood to be crucial in bone physiology and pathology. However, the function of the Farnesoid X receptor (FXR), a member of the NR family, in regulating bone homeostasis remains incompletely understood.

Department of Pharmaceutics, School of Pharmacy, University of Washington, Seattle, Washington. Electronic address:
To further the development of an in vitro model that faithfully recapitulates drug disposition of orally administered drugs, we investigated the utility of human enteroid monolayers to simultaneously assess intestinal drug absorption and first-pass metabolism processes. We cultured human enteroid monolayers from 3 donors, derived via biopsies containing duodenal stem cells that were propagated and then differentiated atop permeable Transwell inserts, and confirmed transformation into a largely enterocyte population via RNA sequencing analysis and immunocytochemistry (ICC) assays. Proper cell morphology was assessed and confirmed via bright field microscopy and ICC imaging of tight junction proteins and other apically and basolaterally localized proteins.

Background: Arteriovenous (AV) fistulas are the preferred access for dialysis but have a high incidence of failure. This study aims to understand the crosstalk between skeletal muscle catabolism and AV fistula maturation failure.
Methods: Skeletal muscle metabolism and AV fistula maturation were evaluated in mice with chronic kidney disease (CKD).
