Atrial natriuretic factor (ANF)-immunoreactivity was identified with peroxidase-antiperoxidase staining and immunoelectron microscopic gold labeling techniques in atrial tissues of fetal, newborn and adult Syrian hamsters.
A MTT/formazan assay was used to evaluate the antitumor activity of vitamin C (Vit C), vitamin K3 (Vit K3), or vitamin C:vitamin K3 combinations against a human prostatic carcinoma cell line (DU145). Both Vit C and Vit K3 alone exhibited antitumor…
Using light, transmission (TEM) and scanning (SEM) electron microscopy, cocaine-induced defects were observed in hamster atria. Compared with controls, the treated atria from neonates show endocardial and myocardial damages as the atrial walls…
Cardiac eccentric hypertrophy is associated with complex architectural and metabolic alterations. Atrial and ventricular myocyte diameters in cardiomyopathic (Bio 14.6) and age-matched control (F1b) Syrian hamsters were compared and histopathology…
The endocardium ultrastructure of 13 embryonic day old hamsters was examined, especially in relationship with the atrial myocytes. The endothelial morphology was described, including the junctional attachments and their relationships with subjacent…
Atherosclerosis, a major macrovascular complication associated with diabetes, poses a tremendous burden on national health care expenditure. Despite extensive efforts, cost-effective remedies are unknown. Therapies for atherosclerosis are challenged…
Resveratrol inhibits herpes simplex virus (HSV) replication by an unknown mechanism. Previously it was suggested that this inhibition may be mediated through a cellular factor essential for HSV replication [Docherty, J.J., Fu, M.M., Stiffler, B.S.,…
This study presents a statistical analysis of variability in six measures of enamel prism and ameloblast size and spacing gathered using confocal microscopy, and applies the results to a consideration of appropriate sampling strategies for taxonomic…
Normal murine metapodophalangeal sesamoid bones, closely associated with tendons, were examined in terms of their structure and mineralization with reference to their potential function following crystal deposition. This study utilized radiography,…
During corneal development, neural crest derivatives from the periocular mesenchyme migrate into the cornea and differentiate into corneal fibroblasts. During this time, these cells interact with a variety of extracellular matrices for proper…
The characteristics of two clinical isolates of HSV-1 obtained from an oral (424) and an anal (490) lesion were compared with the highly passaged KOS strain. In contrast to KOS, the clinical isolates produced small plaques, were more cell-associated…
Whether to stage degeneration or investigate early pathology in glaucoma, examination of axonal structure and function is essential. There are a wide variety of methods available to investigators using animal models of glaucoma, with varying…
PURPOSE: Decreased ATP correlates with intraocular pressure exposure in the optic nerves of mice with glaucoma. To understand what underlies this energy deficit, we examined mitochondria in the myelinated optic nerve axons of the DBA/2J mouse, a…
We present a three-dimensional mineralizing model based on a hollow fiber bioreactor (HFBR) inoculated with primary osteoblasts isolated from embryonic chick calvaria. Using non-invasive magnetic resonance microscopy (MRM), the growth and development…
Whether a vesicobullous disease is intraepidermal or subepidermal is often difficult to determine from the clinical examination. The Tzanck preparation can provide clues that aid in the diagnosis of a number of diseases. It is particularly helpful in…
