Mutations in RABL3 alter KRAS prenylation and are associated with hereditary pancreatic cancer.

Pancreatic ductal adenocarcinoma is an aggressive cancer with limited treatment options. Approximately 10% of cases exhibit familial predisposition, but causative genes are not known in most families. We perform whole-genome sequence analysis in a family with multiple cases of pancreatic ductal adenocarcinoma and identify a germline truncating mutation in the member of the RAS oncogene family-like 3 (RABL3) gene.

Histopathology and external examination of heavily parasitized Lost River Sucker Deltistes luxatus (Cope 1879) and Shortnose Sucker Chasmistes brevirostris (Cope 1879) from Upper Klamath Lake, Oregon.

Shortnose Sucker (Chasimistes brevirostris) and Lost River Sucker (Deltistes luxatus) are endemic to the Upper Klamath Basin of Southern Oregon and Northern California, and their populations are in decline. We used histopathology and external examination of 140 and external examination only of 310 underyearling suckers collected in 2013, 2015 and 2016 to document pathological changes, particularly those relating to parasites. The most severe infection was caused by a Contracaecum sp.

Esthesiometric evaluation of corneal analgesia after topical application of 1% morphine sulfate in normal horses.

Objective: To evaluate whether topical ocular application of 1% morphine sulfate would change corneal sensitivity and to identify the duration of action.

Animal Studied: Eight healthy adult horses.

Procedure: Corneal touch threshold (CTT) was measured in the center of one randomly selected eye of each horse by Cochet-Bonnet esthesiometer (Luneau Cochet-Bonnet Esthesiometer; Western Ophthalmics, Lynnwood, WA, USA).

A novel tamponade agent for management of post partum hemorrhage: adaptation of the Xstat mini-sponge applicator for obstetric use.

Background: Although uterine tamponade is an effective treatment for postpartum hemorrhage (PPH), current methods have key limitations in their use, particularly in low resource settings. The XStat™ Mini Sponge Dressing (MSD) is approved for the management of non-compressible wounds in the battlefield/trauma setting. The MSD applies highly compressed medical sponges capable of stopping high-flow arterial bleeding within seconds.

Selenoprotein H is an essential regulator of redox homeostasis that cooperates with p53 in development and tumorigenesis.

Selenium, an essential micronutrient known for its cancer prevention properties, is incorporated into a class of selenocysteine-containing proteins (selenoproteins). Selenoprotein H (SepH) is a recently identified nucleolar oxidoreductase whose function is not well understood. Here we report that seph is an essential gene regulating organ development in zebrafish.

The effects of venting and decompression on Yellow Tang (Zebrasoma flavescens) in the marine ornamental aquarium fish trade.

Each year, over 45 countries export 30 million fish from coral reefs as part of the global marine ornamental aquarium trade. This catch volume is partly influenced by collection methods that cause mortality. Barotrauma in fish resulting from forced ascent from depth can contribute to post-collection mortality.

Analysis of koi herpesvirus latency in wild common carp and ornamental koi in Oregon, USA.

Koi herpesvirus (KHV) infection is associated with high mortalities in both common carp (Cyprinus carpio carpio) and koi carp (Cyprinus carpio koi) worldwide. Although acute infection has been reported in both domestic and wild common carp, the status of KHV latent infection is largely unknown in wild common carp. To investigate whether KHV latency is present in wild common carp, the distribution of KHV latent infection was investigated in two geographically distinct populations of wild common carp in Oregon, as well as in koi from an Oregon-based commercial supplier.

Pulmonary arteriovenous malformation in two adult alpacas (Vicugna pacos).

Two cases of pulmonary vascular anomaly in unrelated adult alpacas (Vicugna pacos) are described. In the first case, a 9-year-old intact male alpaca presented at Oregon State University Veterinary Teaching Hospital with bilateral epistaxis and died the subsequent day following severe hemorrhage from the mouth and nostrils. At necropsy, a tortuous vascular lesion was identified in the right cranial lung lobe, associated with hemorrhage into airways.

Investigation of koi herpesvirus latency in koi.

Koi herpesvirus (KHV) has recently been classified as a member of the family of Alloherpesviridae within the order of Herpesvirales. One of the unique features of Herpesviridae is latent infection following a primary infection. However, KHV latency has not been recognized.

Results of total DNA measurement in koi tissue by Koi Herpes Virus real-time PCR.

Koi Herpes Virus (KHV) has been classified recently as a member of the Alloherpesviridae within the Herpesvirales order (Waltzek et al., 2005). Although one of the unique features of Herpesviridae, the sister family of Herpesvirales, is latent infection, it has not been demonstrated consistently that KHV of Alloherpesviridae can cause latent infection and be reactivated from latency.

Knockdown of bicaudal C in zebrafish (Danio rerio) causes cystic kidneys: a nonmammalian model of polycystic kidney disease.

Polycystic kidney disease (PKD) is one of the leading causes of end-stage renal disease in humans and is characterized by progressive cyst formation, renal enlargement, and abnormal tubular development. Currently, there is no cure for PKD. Although a number of PKD genes have been identified, their precise role in cystogenesis remains unclear.

Gastric smooth muscle hamartoma in a cat.

An 11-year-old cat presented for evaluation of intermittent vomiting, constipation and hyporexia of 3 weeks duration. Ultrasonographic and endoscopic examination revealed a soft tissue mass adjacent to the lower gastro-esophageal sphincter. Surgical excision of the mass was successfully performed resulting in a resolution of clinical signs.

Eimeria macusaniensis infection in 15 llamas and 34 alpacas.

Case Description: 15 llamas and 34 alpacas between 3 weeks and 18 years old with fecal oocysts or intestinal coccidial stages morphologically consistent with Eimeria macusaniensis were examined. Nineteen of the camelids were admitted dead, and 30 were admitted alive. Camelids admitted alive accounted for 5.

Encrusted cystitis secondary to Corynebacterium matruchotii infection in a horse.

A 17-year-old gelding was evaluated because of dysuria, inappetence, and weight loss. Cystoscopy revealed severe mucosal ecchymoses with luminal hemorrhage and accumulations of crystalloid sludge. Analysis of a urine sample revealed isosthenuria, an alkaline pH, pyuria, hematuria, bacteriuria, and numerous calcium carbonate crystals.

Keratinizing ameloblastoma in a 9-month-old llama (Lama glama).

A 9-month-old male llama (Lama glama) was presented because of a rapidly growing mass on the right side of the face. Radiographs revealed a marked expansion of the right caudal face region with bone lysis involving the maxilla and the nasal, lacrimal, zygomatic, and palatine bones. Cytologically, the mass consisted of atypical round to polygonal cells with round nuclei and basophilic cytoplasms that formed acini and rows.

The relationship between endogenous cortisol, blood micronutrients, and neutrophil function in postparturient Holstein cows.

Neutrophil function, blood micronutrients, and cortisol concentrations were measured in 43 clinically healthy postparturient Holstein cows. Estimated 305-day mature equivalent milk production and neutrophil function were related to results of the blood micronutrient concentrations and neutrophil function tests. Cattle had low to normal zinc concentrations; normal to high selenium, vitamin E, and cortisol concentrations; and normal copper concentrations.

Bile acids in gastric fluids from llamas and alpacas with and without ulcers.

To investigate the relationship between duodenogastric reflux and ulceration, gastric fluid was collected from the 1st (n = 26) and 3rd (n = 45) gastric compartments of llamas and alpacas during postmortem examination. Gastric fluids were analyzed for the presence of bile acids. Additionally, the 3rd compartment was examined grossly for the presence of erosions or ulcers, and the intestines were examined for evidence of fluid distention.

Visceral nodular cartilaginous metaplasia in rockfishes (Sebastes spp.) in the eastern North Pacific Ocean.

Multiple, discrete, nodular foci of cartilaginous metaplasia were found in the spleens and kidneys of rockfishes taken from the northeastern Pacific Ocean during a survey to determine the incidence and the nature of diseases in these animals. These nodules sometimes occurred in association with granulomatous inflammation and distinct granulomas. Many of these fish were infected by Ichythophonus spp.
