Transplantation of pancreatic islets can provide long-lasting insulin independence for diabetic patients, but the current islet supply is limited. Here we describe a new in vitro system that utilizes adult human pancreatic islet-enriched fractions to

The posterior half of the channel catfish intestine has a similar histological organization to that of other teleost fishes. This region is organized into a muscosa, a submucosa, a double layered muscularis and a serosa. A "stratum compactum" of dens

The organization, morphological characteristics, and synaptic structure of photoreceptors in the adult zebrafish retina were studied using light and electron microscopy. Adult photoreceptors show a typical ordered tier arrangement with rods easily di

The ultrastructure of the optic nerve, brain, and some associated structures of larval zebrafish, grown under three different light regimens were studied. Fish grown under cyclic light (control), constant dark (CD), and constant light (CL) were studi

Pt nanoparticles (NPs) of different shape (cubic and octahedral/tetrahedral) and size (5–10 nm) were synthesized by one-step polyol-based synthetic procedures that permit the concomitant control of the shape and size. The shape and size stability o

This study reports on morphological features of hepatic portal tracts in the liver of a rhesus monkey. The light microscope shows that the number of each type of principal component comprising a portal tract varies but that there are usually one to f

Based on a polyol process, one-step synthetic procedures were investigated for concomitant control of the shape and size of platinum nanoparticles (Pt NPs). Cubic and octahedral/tetrahedral particles of different sizes (5–10 nm) were synthesized us

Ketogenic diets are used in the treatment of epilepsy in children refractory to drug therapy. This study identifies changes in liver morphology in rats fed four different diets: a normal rodent chow diet, a calorie-restricted high-fat (ketogenic) die

Four tunnels off the lumen of the proventriculus of the carpenter bee, Xylocopa virginica virginica, have been discovered. Light and electron micrographs revealed the presence in the tunnels of gram-positive, rod-shaped bacteria, some of which showed
