Magnetization of graphene tubules
Physical Review B, 1995Magnetization (M) comes from both the persistent currents and the spin polarization. The spin-B interaction is important in a graphene tubule, because it makes the one-dimensional subband with the divergent density of states capable of crossing the Fermi level (${\mathit{E}}_{\mathit{F}}$=0 eV).

Extracellular Tubules in Semen
Journal of Andrology, 1990Tubules were observed in the semen of two patients, one of whom was fertile. The tubules measured 75 to 90 nm in diameter and were extracellular. However, they frequently were found in amorphous material reminiscent of cell debris and in association with cells, most of which were immature.

Role of Transverse Tubules (T-Tubules) in Muscle Glucose Transport
1998The first data to demonstrate glucose transporter translocation in muscle used membranes enriched in sarcolemma because it was assumed that this was the equivalent of the cell membrane of adipocytes. We studied translocation in intact human muscle using immunogold labeling of the GLUT4 transporter but found very little labeling on the sarcolemma.

Hospital Practice, 1982
Genetic defects in tubule function, although relatively rare, have served as models for the study of the more common acquired renal tubular disorders. Defects in reabsorption or secretion or in hormone production or action are primarily involved. An exact physiologic mechanism has been delineated for some of them, leading to effective management of the

Tubulitis in the kidney is defined as the presence of inflammatory cells in the tubular wall (OOi et al. 1975). It is the hallmark of tubulointerstitial nephritis (OLsen etal. 1986) and one of the important lesions in acute renal allograft rejection (SOlez et al. 1993). However, it may occur in other renal diseases as well, e.g., glomerulonephritis and

The morphology of the proximal tubule cells was covered briefly in Chapter 2, but will be considered in more detail here. The proximal tubule is divisible into the convoluted portion, or pars convoluta, which begins immediately behind the glomerulus, and the straight portion, or pars recta, which passes into the medulla to become the loop of Henle. The

Variable t-tubule organization and Ca2+ homeostasis across the atria.
American Journal of Physiology. Heart and Circulatory Physiology, 2014Although t-tubules have traditionally been thought to be absent in atrial cardiomyocytes, recent studies have suggested that t-tubules exist in the atria of large mammals. However, it is unclear whether regional differences in t-tubule organization exist

Publisher Summary This chapter focuses on the various diseases involving renal tubule, which plays a key role in the body's regulation of fluid, electrolyte, and acid–base balance. The vast majority of water and electrolytes in the glomerular ultrafiltrate are reabsorbed along the tubule by specialized transporters and channels, specifically localized

Endocytic receptors in the renal proximal tubule.
Physiology, 2012Protein reabsorption is a predominant feature of the renal proximal tubule. Animal studies show that the ability to rescue plasma proteins relies on the endocytic receptors megalin and cubilin.

Hollow mesoporous silica fibers: tubules by coils of tubules
Physical Chemistry Chemical Physics, 2001Hollow mesoporous silica fibers have been synthesized under acidic conditions in a two-phase static system. The fibers always have a circular internal architecture with hexagonally arranged channels running perpendicularly around the fiber axis. The inner radius of the hollow fibers is variable and the fibers are connected with solid fibers without ...
