Endoscopic ultrasound-guided biopsy of healthy pig pancreas - Towards the histological diagnosis of chronic pancreatitis.

Background: diagnosis of early chronic pancreatitis (CP) is a challenge due to the lack of accurate methods. The ability of endoscopic ultrasound (EUS) guided biopsy to obtain pancreatic core tissue samples in patients with minimal changes of CP and its potential use for the histological diagnosis of early CP are unknown. The aim of the study was to evaluate the ability of different EUS-guided biopsy core needles to obtain histological samples of healthy pig pancreas.

Computed Tomographic Findings in Dogs with Hepatic Bacterial Parenchymal Infection and Abscessation.

Bacterial liver parenchymal infections in dogs are rarely documented, and their imaging characteristics are scarce in the veterinary literature, especially in Computed Tomography (CT). This retrospective multicentric study aimed to describe the CT characteristics of parenchymal bacterial liver infection and abscessation in dogs and compare them with the human literature. Twenty dogs met the inclusion criteria.

Second world record for Barathronus roulei Nielsen, 2019 (Ophidiiformes, Bythitidae), from the Porcupine Bank (Northeast Atlantic).

Barathronus is a genus of blind cusk eels comprising 11 valid species. In this paper, we report the second specimen ever documented of Barathronus roulei (Bythitidae) obtained from the Porcupine Bank by R.V.

Trace element status in canine endocrine diseases.

A balanced trace element status is essential for the optimal functioning of all organisms. However, their concentrations are often altered in diverse medical conditions. This study investigated the trace element profiles in plasma samples of dogs with endocrine diseases and used chemometric techniques to explore their associations with biochemical data.

Ultrasonographic anatomy of the palmar region of the carpus of the dog.

The palmar region of the canine carpus may be injured by traumatic, inflammatory, infectious, neoplastic, and degenerative disorders. The normal ultrasonographic anatomic features of the dorsal region of the canine carpus have been published, however information regarding the palmar region is currently lacking. The aims of this prospective, descriptive, anatomic study were (1) to describe the normal ultrasonographic characteristics of the palmar carpal structures in medium to large-breed dogs, and (2) to establish a standardized ultrasonographic protocol for evaluating them.

Oesophageal pneumatosis: computed tomographic characteristics in three dogs (2018-2021).

Background: Oesophageal pneumatosis (OP) is defined as the presence of gas within the oesophageal wall. The description of this condition in veterinary medicine is currently lacking. The pathogenesis of alimentary tract pneumatosis remains unclear.

Study of Behavioural Traits in Can de Palleiro (Galician Shepherd Dog).

The Can de Palleiro (CP) is an autochthonous canine breed from Galicia (NW Spain). Interestingly, no previous research has been published about the behaviour of this breed. Thus, the aim of the present study was to obtain a deeper understanding of CP behavioural and temperamental traits and detect any potentially problematic behaviour by using the Canine Behavioural Assessment and Research Questionnaire (C-BARQ) and the Socially Acceptable Behaviour (SAB) test.

Crambescin C1 Acts as A Possible Substrate of iNOS and eNOS Increasing Nitric Oxide Production and Inducing Hypotensive Effect.

Crambescins are guanidine alkaloids from the sponge . Crambescin C1 (CC) induces metallothionein genes and nitric oxide (NO) is one of the triggers. We studied and compared the , effects of some crambescine A and C analogs.

Ultrasonographic anatomy of the dorsal region of the carpus of the dog.

The dorsal region of the canine carpus is anatomically complex and its normal ultrasonographic characteristics have not been published. The aims of this prospective, descriptive, anatomic study were (a) to describe the normal ultrasonographic appearance of the dorsal carpal structures in medium to large breed dogs, and (b) to describe a standardized protocol for evaluations. The final study, based on the methodology developed in a pilot study performed in twenty-two carpi, comprised two phases: (a) identification phase, in which a correlation between ultrasound and dissection and anatomic slices was performed in forty-eight cadaver carpi and the ultrasonographic protocol was developed; and (b) descriptive phase, in which the ultrasonographic characteristics of the examined structures in 23 carpi of 12 alive adult and healthy dogs were recorded.

Skeletal Anomalies in Senegalese Sole ( Solea senegalensis), an Anosteocytic Boned Flatfish Species.

Skeletal anomalies affect animal welfare and cause important economic problems in aquaculture. Despite the high frequency of skeletal problems in reared Solea senegalensis, there is lack of information regarding the histological features of normal and deformed vertebrae in this flatfish. The aim of this study was to describe the histopathological and radiographical appearance of vertebral body anomalies.

Human Poisoning from Marine Toxins: Unknowns for Optimal Consumer Protection.

Marine biotoxins are produced by aquatic microorganisms and accumulate in shellfish or finfish following the food web. These toxins usually reach human consumers by ingestion of contaminated seafood, although other exposure routes like inhalation or contact have also been reported and may cause serious illness. This review shows the current data regarding the symptoms of acute intoxication for several toxin classes, including paralytic toxins, amnesic toxins, ciguatoxins, brevetoxins, tetrodotoxins, diarrheic toxins, azaspiracids and palytoxins.

Polymerase chain reaction detection of Bartonella spp. in dogs from Spain with blood culture-negative infectious endocarditis.

Objectives: The presence of Bartonella spp. was detected by polymerase chain reaction (PCR) in dogs from Spain with blood culture-negative endocarditis. The aim of this study is to add information about canine infectious endocarditis in Europe.

Subacute immunotoxicity of the marine phycotoxin yessotoxin in rats.

Yessotoxin (YTX) is a marine phycotoxin produced by dinoflagellates and accumulated in filter feeding shellfish. YTX content in shellfish is regulated by many food safety authorities to protect human health, although currently no human intoxication episodes have been unequivocally related to YTX presence in food. The immune system has been proposed as one of the target organs of YTX due to alterations of lymphoid tissues and cellular and humoral components.

In vivo cardiomyocyte response to YTX- and AZA-1-induced damage: autophagy versus apoptosis.

Yessotoxins (YTX) and azaspiracids (AZAs) are marine toxins produced by phytoplanktonic dinoflagellates that get accumulated in filter feeding shellfish and finally reach human consumers through the food web. Both toxin classes are worldwide distributed, and food safety authorities have regulated their content in shellfish in many countries. Recently, YTXs and AZAs have been described as compounds with subacute cardiotoxic potential in rats owed to alterations of the cardiovascular function and ultrastructural heart damage.

Subacute Cardiovascular Toxicity of the Marine Phycotoxin Azaspiracid-1 in Rats.

Azaspiracids (AZAs) are marine toxins produced by Azadinium spinosum that get accumulated in filter feeding shellfish through the food-web. The first intoxication was described in The Netherlands in 1990, and since then several episodes have been reported worldwide. Azaspiracid-1, AZA-2, and AZA-3 presence in shellfish is regulated by food safety authorities of several countries to protect human health.

Acute cardiotoxicity evaluation of the marine biotoxins OA, DTX-1 and YTX.

Phycotoxins are marine toxins produced by phytoplankton that can get accumulated in filter feeding shellfish. Human intoxication episodes occur due to contaminated seafood consumption. Okadaic acid (OA) and dynophysistoxins (DTXs) are phycotoxins responsible for a severe gastrointestinal syndrome called diarrheic shellfish poisoning (DSP).
