Objective: To compare the efficacy of osteoprogenitors in fibrin glue to fibrin glue alone in bone healing of surgically induced ostectomies of the fourth metacarpal bones in an equine model. Study Design: Experimental. Animals: Adult horses (n=10). Methods: Segmental ostectomies of the 4th metacarp...

Sturgeon aquaculture has increased considerably worldwide but little is known about their immunological development and competence in early life stages. Culture of larvae is one of the most critical stages in intensive sturgeon farming, often associated with high mortality rates. The objective of th...

Congenital Anomalies of the Kidney and Urinary Tract (CAKUT) are a polymorphic group of clinical disorders comprising the major cause of renal failure in children. Included within CAKUT is a wide spectrum of developmental malformations ranging from renal agenesis, renal hypoplasia and renal dysplasi...

Trichocyst morphology and development were explored using transmission electron microscopy in Hematodinium spp. isolated directly from Atlantic snow crab (Chionoecetes opilio) hemolymph and from in vitro cultures. Appearance of trichocysts defines the initiation of a morphological transition in the ...

Sturgeon are an important evolutionary taxa of which little is known regarding their responses to environmental factors. Water temperature strongly influences growth in fish; however, its effect on sturgeon immune responses is unknown. The objective of this study was to assess how 2 different temper...

The morphology and the histochemistry from the mucus of the posterior esophagus of the winter flounder and the yellowtail flounder were examined using light and electron microscopy. The esophageal mucosa of both species was organized into elaborate branching folds. The epithelium consisted of a stra...

Immunoreactivity to growth hormone (GH), prolactin (PRL), and thyroid-stimulating hormone (TSH) was found in the adenohypophysis of the sea lamprey, Petromyzon marinus L., during its upstream migration, by immunoperoxidase techniques with antisera to mammalian pituitary hormones. Cross-reactivity to...

The histology and mucus histochemistry of the pleuronectid post-gastric alimentary canal was examined using light and electron microscopy. Distinct differences in goblet cell mucus histochemistry were observed between species, with the two closest taxonomic species, the winter flounder and the yello...

BACKGROUND: Adenosine triphosphate (ATP) is a critical determinant of beta-cell insulin secretion in response to glucose. BHE/cdb rats have a mutation in ATP synthase that limits ATP production, yet develop mild diabetes only with ageing. We investigated the cellular basis for reduced insulin secret...

We measured low substrate (<1 nM) thyroid hormone (TH) deiodination activities in liver, muscle, intestine, and brain microsomes of Atlantic hagfish fasted for 2 weeks and found extremely low thyroxine (T-4) outer-ring deiodination (T4ORD) and inner-ring deiodination (T4IRD) as well as 3,5,3'-tri...

Infectious salmon anaemia (ISA) virus (ISAV) is a fish orthomyxovirus that has recently been assigned to the new genus Isavirus within the family Orthomyxoviridae. It possesses the major functional characteristics of the virus family including haemagglutinating, receptor destroying enzyme (RDE), and...

Frozen sections of unfixed tibia and mandibles from day-old rats were immunostained by the peroxidase-antiperoxidase technique after exposure to antisera against procollagen I or other collagenous materials. Light microscopic study of bone growth areas showed that procollagen I antigenicity was pres...

Chondrogenesis of the trabeculae, non-collagen-based cartilages in prolarval stages of the sea lamprey, Petromyzon marinus, was examined by light and electron microscopy. Chondrogenesis of the trabecular cartilages in prolarval lampreys commenced with the formation of mesenchymal condensations. Two ...

The ultrastructure of the adenohypophysis (AH) in the larval anadromous sea lamprey, Petromyzon marinus L., was examined. The AH is subdivided into three regions, the pro-, meso-, and meta-AH. Cells of the nasopharyngeal stalk extend directly beneath the pro- and meso-AH to form the ventral surface ...

Rainbow trout, in groups of 3, were exposed to 109 cfu/ml Vibrio anguillarum in fresh or salt water, or were kept in non-infected fresh water. Gill filaments were removed from the fish and studied by light and electron microscopy. Eosoinophil granule cells were present throughout the tissue in assoc...
