Abstract In brachycephalic dogs, the skull bone shortening is not paralleled by a decreased development of soft tissues. Relatively longer palate one main factors contributing to pharyngeal narrowing during normal respiratory activity these dog breeds, which are frequent carriers airway obstructive syndrome (BAOS), affects most part them their postnatal life. No histological studies assessing morphology and tissue composition in dogs available, neither has ever been determined whether...

Abstract Background The identification of the adipocyte-derived obesity gene product, leptin (Ob), and subsequently its association with reproduction in rodents humans led to speculations that may be involved regulation oocyte preimplantation embryo development. In mice pigs, vitro addition significantly increased meiotic resumption promoted development a dose-dependent manner. This study was conducted determine whether supplementation during maturation (IVM) horse oocytes could have effects...

Pathological and immunohistochemical investigations were carried out on the middle intestine of uninfected parasitized brown trout, Salmo trutta L., from Ceresone Channel in North Italy. Eighty‐six trout sampled by electrofishing, 32 (37.2%) infected with Cyathocephalus truncatus Pallas, 1781 (Cestoda). The intensity infection ranged 1 to 82 parasites per host most segments anterior (near pyloric caeca region) central part intestine. Immunohistochemical tests applied sections intestinal...

Background Dermoscopy is a diagnostic tool that can reveal morphological structures not visible upon clinical examination. Hypothesis/Objectives To assess the usefulness and applicability of dermoscopy for examination healthy cat skin. Animals Twenty‐one domestic short‐haired cats from feline rescue association. Methods Four regions (head, dorsal neck, sacral abdominal regions) were examined with both contact hand‐held nonpolarized light dermoscope at 10‐fold magnification videodermoscope...

At hatching the gut of sole Solea solea was a primitive epithelial tube which showed vigorous cellular proliferation but only initial regionalization, and no secretory cells. By contrast, at this stage lateral muscle already consisted clearly distinct superficial monolayer parvalbumin‐negative fibres, deeper layer parvalbumin‐positive (presumptive fastwhite) fibres. There were very small‐diameter fibres present few proliferating cell nuclear antigen (PCNA)‐positive nuclei, indicating that...

Four different aquaporins (AQP1, 2, 5 and 9), integral membrane water channels that facilitate rapid passive movement of water, were immuno-localized in the excurrent ducts collected from sexually mature cats during orchiectomy. Aquaporins 1, 2 9, at distinct levels, whereas AQP5 was undetectable all along feline genital tract. No immunoreactivity present level rete testis with any antibodies tested. In efferent ducts, AQP1-immunoreactivity strongly evidenced apical surface non-ciliated...

The gross anatomy and overall structure of the soft palate has been described in average dog's head, however, no descriptive microanatomical studies dog are available, despite their possible utility view manifold important repercussions this organ physiology. This is first two companion papers, dealing with caudal part canine species, mesaticephalic brachycephalic dogs. Specimens from healthy dogs (N = 8) were collected after euthanasia, processed for histology sectioned at six transversal...

ABSTRACT A thickened and abnormally long soft palate is mostly involved in the pathogenesis of both nasopharyngeal oropharyngeal narrowing, affecting respiratory activity virtually all brachycephalic dogs suffering from Brachycephalic Airway Obstructive Syndrome (BAOS). The morphology adult mesaticephalic has been previously described. In this article specimens dog neonates ( N = 10) dead one to 3 hr after birth unrelated conditions were collected histologically evaluated at three transverse...

The presence of intestinal helminths in the alimentary canal brown trout, Salmo trutta L., can alter number cells that synthesize modulatory peptides. A total 167 trout were collected from tributaries River Brenta (northern Italy), which 119 (71.3%) specimens infected with enteric helminths, 28 acanthocephalan Pomphorhynchus laevis Müller, 1776 intensity infection ranging 1 to 162 (18.57 +/- 30.79) worms per host and 67 fish cestode Cyathocephalus truncatus Pallas, 1781. Intensity C. ranged...

Dermoscopic studies evaluating noninflammatory, nonpruritic progressive alopecia attributable to pattern are currently unavailable.To evaluate the dermoscopic features observed in healthy skin of short coated dogs and compare these findings with those affected by diagnosed clinical dermatopathological examination.Thirty male female, healthy, breed matched, young adult, (controls) 30 alopecia.Dermoscopy was performed a Fotofinder II videodermoscope equipped software that allowed measurement...
