Anti-inflammatory effects of polydeoxyribonucleotide and adipose tissue-derived mesenchymal stem cells in a canine cell model of osteoarthritis.

Importance: A relatively new therapeutic agent for osteoarthritis (OA), polydeoxyribonucleotide (PDRN), shows potential in treating human OA due to its regenerative and anti-inflammatory effects. However, studies on PDRN for canine OA are limited, and no study has investigated their use with mesenchymal stem cells (MSCs) conventionally used for OA treatment.

Objective: This study aimed to evaluate the potential of PDRN and explore its combined effect with adipose tissue-derived MSCs (AdMSCs) in treating canine OA.

Development of non-pulmonary soft-tissue metastasis is not a poor prognostic indicator in dogs with metastatic appendicular osteosarcoma.

Objectives: To evaluate whether patient factors affect development of non-pulmonary soft-tissue metastases following treatment of canine appendicular osteosarcoma and to report and compare outcomes to those in dogs with pulmonary or osseous metastases.

Animals And Procedure: The records of 3 veterinary teaching hospitals were reviewed to identify dogs that received definitive treatment for a primary appendicular osteosarcoma lesion and chemotherapy between January 2010 and June 2022. Dogs with non-pulmonary metastases following initial treatment were included.

Equine intraocular melanocytic neoplasia.

Objective: To describe the clinical appearance, histopathology, and treatment of equine intraocular melanocytic neoplasia in adult horses.

Animals And Procedure: A retrospective review of medical records was conducted. Data recorded included signalment, ocular examination findings, physical examination findings, therapeutic interventions, and case outcomes.

Transcriptomic identification of genes associated with thrombosis and coagulation in lipopolysaccharide-exposed bovine monocyte-derived macrophages.

Objective: The objective of this study was to investigate the differential expression of genes associated with coagulation in bovine monocyte-derived macrophages (MoMΦ) exposed to lipopolysaccharide (LPS) in vitro. We hypothesized that MoMΦ stimulated with LPS would have upregulation of procoagulant genes and downregulation of genes protecting against coagulation.

Methods: MoMΦ were isolated from Holstein steers and exposed to Escherichia coli-derived LPS or a control for 3 hours.

Snakes as sentinel of zoonotic yeasts and bio-indicators of environmental quality.

Reptiles in the wild or as pets may act as spreaders of bacteria, viruses, fungi and parasites. However, studies on the mycobiota of these animals are scanty. This study investigates the occurrence of yeasts from the cloacal swabs of snakes of different origins and the antifungal profile of the isolated strains.

Effects of Omega-3 Polyunsaturated Fatty Acids on the Formation of Adipokines, Cytokines, and Oxylipins in Retroperitoneal Adi-Pose Tissue of Mice.

Oxylipins and specialized pro-resolving lipid mediators (SPMs) derived from polyunsaturated fatty acids (PUFAs) are mediators that coordinate an active process of inflammation resolution. While these mediators have potential as circulating biomarkers for several disease states with inflammatory components, the source of plasma oxylipins/SPMs remains a matter of debate but may involve white adipose tissue (WAT). Here, we aimed to investigate to what extent high or low omega (n)-3 PUFA enrichment affects the production of cytokines and adipokines (RT-PCR), as well as oxylipins/SPMs (liquid chromatography-tandem mass spectrometry) in the WAT of mice during lipopolysaccharide (LPS)-induced systemic inflammation (intraperitoneal injection, 2.

Evaluating the Physiologic Effects of Alfaxalone, Dexmedetomidine, and Midazolam Combinations in Common Blue-Tongued Skinks ().

Common blue-tongued skinks () are popular pet reptiles; however, there has been limited research to investigate sedatives for this species. The purpose of this study was to measure the physiologic effects of four combinations of alfaxalone, dexmedetomidine, and midazolam for minor procedures such as intubation and blood collection. Eleven common blue-tongued skinks () were used for this prospective, randomized cross-over study.

Effect of supplementing algae to breeding and early gestation first calf heifers on growth and reproduction.

Fat supplementation has potential to improve reproductive performance and increase pregnancy rates in cattle by increasing the energy density of the diet. However, some of the positive effects of fat seem to be influenced by the type of fatty acid fed. Docosahexaenoic acid (DHA, 22:6n-3) and eicosapentaenoic acid (EPA, 20:5n-3) are long-chain n-3 poly-unsaturated fatty acids (PUFA) that have important biological effects on reproduction through their involvement in hormone and series 3 prostaglandin synthesis.

Toxicity Profile of eBAT, a Bispecific Ligand-Targeted Toxin Directed to EGFR and uPAR, in Mice and a Clinical Dog Model.

EGFR-targeted therapies are efficacious, but toxicity is common and can be severe. Urokinase type plasminogen activator receptor (uPAR)-targeted drugs are only emerging, so neither their efficacy nor toxicity is fully established. Recombinant eBAT was created by combining cytokines EGF and uPA on the same single-chain molecule with truncated toxin.

A Reference Interval for CT-Based Liver Volume in Dogs without Hepatic Disease.

In both human and veterinary medicine, computed tomography (CT) volumetry provides a quantitative and accurate measure of liver volume. While CT volumetry is recognized as a useful method for assessing liver volume in dogs, a statistically significant reference interval for liver volume in dogs with no history of hepatic disease has not been reported. The purpose of the present study was to define a reference interval for liver volume with no history of hepatic disease using CT volumetry.

Computed Tomographic Hepatic Volumetry in Dogs with Congenital Portosystemic Shunts.

CTHV is a non-invasive and accurate method for assessing liver volume in dogs. CTHV has not been studied in each type of extrahepatic PSS in dogs. This study aimed to use CTHV to compare liver volumes in dogs with different types of PSSs that had been confirmed by computed tomography angiography.

Lidocaine-saturated cotton tip applicator used for laryngeal desensitization resulting in an iatrogenic tracheobronchial foreign body in two cats.

Case Series Summary: Two cats were referred to a veterinary teaching hospital with a cotton tip applicator (CTA) tracheobronchial foreign body (FB) after induction of anesthesia for an elective dental cleaning. In both cases, a lidocaine-saturated CTA, utilized to desensitize the larynx before endotracheal (ET) intubation, broke when introduced into the oropharynx and was subsequently aspirated into the tracheobronchial tree. Both CTAs were successfully removed bronchoscopically, and the cats survived with no short- or long-term complications noted.

Effect of hydroalcoholic extract of Sambucus nigra on superficial digital flexor tendon repair in rabbit by ultrasonography and histopathology.

Background: Adult tendon tissue has limited and slow regenerative capacity. Sambucus nigra plant possesses antioxidant and anti-inflammatory attributes.

Objectives: This study aimed to evaluate the effect of hydroalcoholic extract of this plant's fruit on superficial digital flexor tendon repair in rabbits (SDFT).

A "plus one" strategy impacts replication of felid alphaherpesvirus 1, and and the metabolism of coinfected feline cells.

Coinfections are known to play an important role in disease progression and severity. Coinfections are common in cats, but no coinfection studies have investigated the dynamics between feline viral and bacterial pathogens. In this study, we performed co-culture and invasion assays to investigate the ability of common feline bacterial respiratory pathogens, and , to replicate in and invade into Crandell-Rees feline kidney cells.

This research article describes an investigation into the udder health, bacterial isolation and antimicrobial sensitivity of three staphylococcal species isolated from the milk of non-dairy goats, suckling their kids, on two smallholder farms in the Hong Kong Special Administrative Region. Udder lesions were visually noted in 21 of 34 goats and two goats had palpable abnormalities. Collected milk samples grew a total of 11 bacterial organisms and the most frequently isolated organism was .
