Functional reconstruction of inner medullary thin limbs of Henle and collecting ducts (CDs) has enabled us to characterize distinctive three-dimensional vertical and lateral relationships between these segments. We previously reported that inner medullary descending thin limbs (DTLs) that form a bend at a distance greater than approximately 1 mm below the inner medullary base express detectable...

We study the covariant free bosonic string field theory and explore its locality (causality) properties. We find covariant string fields which are strictly local and covariant, but act on an unconstrained Hilbert space with an indefinite inner product. From these we also define observable fields which act on the physical Hilbert space with an definite inner product. These are shown to be approx...

This study gives a three-dimensional (3D) structural analysis of rat nephrons and their connections to collecting ducts. Approximately 4,500 2.5-μm-thick serial sections from the renal surface to the papillary tip were obtained from each of 3 kidneys of Wistar rats. Digital images were recorded and aligned into three image stacks and traced from image to image. Short-loop nephrons (SLNs), long-...

The transmembrane diffusion and equilibrium distribution of spin-labelled phosphatidylethanolamine (PE*), phosphatidylcholine (PC*) and cardiolipin (CL*) were investigated in purified mitochondrial inner membranes using electron spin resonance spectroscopy. Using the back exchange technique, we found that the outside-inside movement of PE* and PC* in beef-heart inner mitochondrial membranes was...
