Ductal occlusion has been postulated to precipitate focal pancreatic inflammation, while the nature of the primary occluding agents has remained elusive. Neutrophils make use of histone citrullination by peptidyl arginine deiminase-4 (PADI4) in contact to particulate agents to extrude decondensed chromatin as neutrophil extracellular traps (NETs). In high cellular density, NETs form macroscopic...
PURPOSE To investigate the osmotic water permeability of lacrimal gland (LG) duct epithelium by means of calculation of filtration permeability and to investigate LG ductal fluid secretion. METHODS Experiments were performed on isolated rabbit LG duct segments maintained in short-term culture. Osmotically determined fluid movement or fluid secretion into the closed intraluminal space of cultu...
AIMS To investigate the effect of combination endocrine treatment (CET) or luteinising hormone releasing hormone agonist and flutamide on non-neoplastic prostate, prostatic intraepithelial neoplasia, and prostatic adenocarcinoma. METHODS The morphology, including the mitotic activity, of 12 radical prostatectomies from patients with prostatic adenocarcinoma pretreated for three months with CE...
The distribution of amylase in rat parotid glands and von Ebner's glands was examined using ion etching-immunoscanning electron microscopy, which enables both light and electron microscopic observations of identical semi-thin resin sections immunolabeled with anti-α-amylase and immunogold in association with silver enhancement. At the light microscopic level, most acinar secretory granules (SG)...
A comparative anatomical study of the stems in 32 taxa assigned two related genera; Matricaria (4 taxa) and Tripleurospermum (28 taxa, 30 accessions), was carried out Turkey by using cluster analysis (CA) principal component (PCA) to address generic classification delimitation. All studied have following stem characteristics: one layer epidermal cells with a sparse distribution non-glandular tr...
The induction of a 15 to 20 fold increase in oleoresin content of resin soaked xylem in paraquat treated pine stems raises many intriguing questions of a physiological nature. Our knowledge of stem anatomy and physiology of oleoresin formation in pines appears to exclude the possibility that resin soaking results from long range transport of oleoresin via vertical resin ducts to resin soaked ar...
The efferent ducts of the Mediterranean Gecko, Hemidactylus turcicus (Gekkonidae) were investigated using light and electron microscopy. The seminiferous tubules unite into a single rete testis tubule. The rete testis divides into 3-4 ductuli efferentes which all drain into the cranial portion of the ductus epididymis. All efferent ducts are most active during the months of December to August. ...
The North American Ground Skink, Scincella lateralis, is a member of the most speciose family of lizards, the Scincidae. The only descriptions of the testicular ducts of skinks concern the light microscopy of 13 species in eight other genera. We combine histological observations with results from transmission electron microscopy on a sample of skinks collected throughout the active season. The ...
