The primary olfactory brain center, the antennal lobe (AL) in insects or the olfactory bulb in vertebrates, is a notable example of a neural network for sensory processing. While physiological properties of the input, the olfactory receptor neurons, have become clearer, the operation of the network itself remains cryptic. Therefore we measured spatio-temporal odor-response patterns in the outpu...

The elastic properties of renal glomeruli and their capillaries permit them to maintain structural integrity in the presence of variable hemodynamic forces. Measured by micro-indentation, glomeruli have an elastic modulus (E, Young's modulus) of 2.1 kPa, and estimates from glomerular perfusion studies suggest that the E of glomeruli is between 2 and 4 kPa. F-actin depolymerization by latrunculi...

BACKGROUND Atubular glomeruli have been identified in a number of chronic renal diseases and have been linked to declining renal function. In type 1 diabetes they are present predominantly in proteinuric patients. We investigated the prevalence of atubular glomeruli in type 2 diabetes and their relationship to renal function. METHODS Renal biopsies from 12 type 2 diabetic patients with nephro...

The goal of this work was to nondestructively measure glomerular (and thereby nephron) number in the whole kidney. Variations in the number and size of glomeruli have been linked to many renal and systemic diseases. Here, we develop a robust magnetic resonance imaging (MRI) technique based on injection of cationic ferritin (CF) to produce an accurate measurement of number and size of individual...

Harmine is a harmal-derived alkaloid with antioxidant properties. The morphine produces free radicals and plays a key role in the pathogenesis of kidney disease. This study was designed to evaluate the effects of harmine against morphine- induced damage to the kidneys of rats. In this study, 64 male rats were randomly assigned to 8 groups: saline and morphine treated groups; harmine groups (5, ...

This article reports data describing HO-1 expression patterns of heme oxygenase (HO)-1 in isolated rat glomeruli and in cultured glomerular epithelial cells (GEC) in response to its natural substrate heme. Qualitative and quantitative data are presented to support presence of a HO-1 expression threshold in glomeruli but not in GEC. Interpretation of our data and further insight into HO-1 expres...

in 6 patients with iron deficiency anemia the proliferation of epi, thelial cells of glomeruli were prominent associated with edema and adherence of bowman's capsule in kidney biopsy, the cause of proliferation is not known.

Cell surface carbohydrates define subpopulations of primary olfactory neurons whose axons terminate in select glomeruli in the olfactory bulb. The combination of carbohydrates present on axon subpopulations has been proposed to confer a unique identity that contributes to the establishment of the olfactory topographic map. We have identified a novel subpopulation of primary olfactory neurons in...
