Based on shell characters, two new species of the gastropod family Trochidae, Jujubinus eleonorae n. sp. and Jujubinus trilloi n. sp., from the Sicily Channel are described. Shells of the new taxa were collected in the lower infralittoral of the Skerki and Talbot Banks, respectively. The new taxa are compared with Jujubinus curinii Bogi & Campani, 2005, morphologically the most closely related ...

The morphological appearance of an osteoblast largely alters with its differentiation and maturation, along with the change of cell function. We quantitatively observed the osteoblast morphology and compared it with bone metabolism. Biopsied iliac bone samples obtained from 77 dialysis patients (14 mild change, 37 osteitis fibrosa, 2 osteomalacia, 8 mixed, and 16 adynamic bone) were included in...

Mast cells have been counted in sections of iliac bone from 61 control subjects at necropsy. Mast cells were found in all but three, and the range was 0-33-7, median 1-95 per mm2 marrow. The majority (82%) had less than 4-99 mast cells per mm2 marrow; in 37-7% there was less than 1 mast cell per mm2 marrow. In a group of 45 patients with chronic renal failure there was a significant increase in...

The role of endothelial cells (ECs) in aortic valve (AV) disease remains relatively unknown; however, disease preferentially occurs in the fibrosa. We hypothesized oscillatory shear (OS) present on the fibrosa stimulates ECs to modify mRNAs and microRNAs (miRNAs) inducing disease. Our goal was to identify mRNAs and miRNAs differentially regulated by OS and laminar shear (LS) in human AVECs (HAV...

La displasia fibrosa es una enfermedad benigna del hueso, de base genética y progresión lenta, que se caracteriza por el reemplazo progresivo hueso normal tejido fibrótico. El proceso puede afectar un solo o múltiples huesos (displasia monostótica poliostótica); esta última estar asociada con enfermedades sindrómicas, como síndrome McCune-Albright. Objetivo Revisar diagnóstico tratamiento los p...

INTRODUCTION Renal osteodystrophy includes the complete range of mineral metabolism disorders that affect the skeleton in patients with chronic renal failure. PATIENTS AND METHODS 200 patients with end-stage renal disease and on dialysis were investigated regarding the clinical, biochemical and histological findings of bone disease. RESULTS The spectrum of renal osteodystrophy consisted mai...
