This study addresses two questions: i) which antigens can withstand bleaching by 2.5 g/L of potassium permanganate followed by 10 g/L of oxalate, before immunohistochemical staining; and ii) are any other steps in the immunohistochemical staining technique resistant to bleaching? A panel of 10
Changes of surface sugar residues in the large intestinal mucosa may be associated with malignant transformation and may be of importance in differentiating borderline lesions. To compare these changes in normal mucosa, adenomas, and carcinomas of the large intestine, we investigated modifications
While the exact mechanism of hepatitis A virus (HAV) accumulation remains unclear, it has been demonstrated that viruses related to shellfish-borne gastroenteritis can bind to carbohydrates of oyster tissues. We investigated carbohydrate-binding sites to determine if they were related to the binding
Few studies have examined how parasite impact is affected by host size. In a glasshouse experiment, we investigated the impact of the Australian native hemiparasitic vine, Cassytha pubescens, on a major invasive shrub, Ulex europaeus, of different sizes. Infected plants had significantly lower
Renal cystic epithelia and peritoneal mesothelia from two humans with autosomal recessive polycystic kidney disease (ARPKD) were grown in culture. Cystic epithelial and mesothelial cells formed continuous monolayers in vitro. By electron microscopy, cystic renal cells exhibited a single apical
The epithelium at the trigone of the urinary bladder showed intestinal metaplasia of a colonic type in three Holstein-Friesian cows affected with chronic polypoid cystitis. Except for Ricinus communis (RCA-I), almost all goblet cells in the whole crypt were positive to periodic acid-Schiff (PAS),
Conventional techniques to visualise microvascular structure often involve fixed tissue slices that provide two-dimensional images. A previous study using diffusive labelling of fresh, dissected tissue samples with fluorescently-tagged endothelial markers demonstrated the possibility of examining
We investigated the hypothesis that lacrimal component accumulation on soft contact lenses (SCL) may be induced by an abnormal protein, glycoprotein, or trace element composition of the tear fluid. Individual tear samples were collected from healthy non-SCL wearers (normal patients) and SCL wearers
OBJECTIVE
In this study, we aimed: (i) to obtain and functionally characterize the cultures of late endothelial progenitor cells (EPCs) from the animal blood; (ii) to investigate the potential beneficial effects of circulating microparticles (MPs) of healthy origins on EPC dysfunctionality in
