Dilutional fluorescent method to measure glomerular albumin reflection coefficient (dσAlb) in vitro

Zeroing in on the albumin glomerular sieving coefficient.

Chronic endothelin-1 infusion elevates glomerular sieving coefficient and proximal tubular albumin reuptake in the rat.

AIM We have previously found that chronic endothelin-1 (ET-1) infusion in Sprague-Dawley rats increases glomerular permeability to albumin (P(alb)) as assessed in vitro independent of blood pressure with no observed albuminuria. In this study, we hypothesized that ET-1 increases glomerular albumin filtration with accompanied increase in albumin uptake via the proximal tubule, which masks the ex...

Glomerular sieving coefficient of serum albumin in the rat: a two-photon microscopy study.

Recent studies of the sieving of serum albumin in the rat kidney using a two-photon microscope suggested that the glomerular sieving coefficient (GSC) of albumin is 0.034, much higher than earlier micropuncture determinations. In the present study, we critically evaluated the use of the two-photon microscope to measure the GSC of albumin in the Munich-Wistar rat in vivo. The albumin GSC average...

Application of characteristic X-rays to measure linear attenuation coefficient of nano-composites used in shielding

Using of X-rays in different industries and especially in medical application is increasing. In this regard, designing of light and efficient protective material based on polymeric nanocomposites and precise study of the effect of adding nanoparticles with different sizes on the X-ray attenuation is necessary. In this study the epoxy nanocomposites with different percentages of copper oxide nan...
