The osteochondrogenic switch of vascular smooth muscle cells (VSMCs) is a pivotal cellular process in atherosclerotic calcification. However, the exact molecular mechanism transition VSMCs remains to be elucidated. Here, we explore regulatory role TXNIP (thioredoxin-interacting protein) phenotypical transitioning toward responsible for calcification.The phenotypes Txnip-/- mice were analyzed combination with single-cell RNA-sequencing. Tagln-Cre; Txnipflox/flox (smooth cell-specific Txnip...
Valvular inflammation triggered by hyperlipidemia has been considered as an important initial process of aortic valve disease; however, cellular and molecular evidence remains unclear. Here, we assess the relationship between plasma lipids valvular inflammation, identify association low-density lipoprotein with increased lipid macrophage accumulation. Single-cell RNA sequencing analysis reveals heterogeneity leukocytes, interstitial cells, endothelial their phenotypic changes during leading...
This study aimed to design and evaluate a novel trans-bleb device (TBD) for draining aqueous humor trapped within fibrotic blebs following Ahmed glaucoma valve (AGV) implantation in dogs. Two clinically normal, purpose-bred Beagles underwent AGV surgery one eye. When bleb was formed with increased intraocular pressure (IOP), the TBD inserted through fenestration created bleb. IOP measurements, slit-lamp biomicroscopic ultrasound (UBM) evaluations were performed during follow-up. Results...
An 11-year-old castrated male Turkish Angora cat presented with chronic lethargy and inappetence was diagnosed non-regenerative anemia, increased nucleated red blood cells, thrombocytopenia. Tests for anemia-related infections were negative. Imaging revealed pleural effusion, hepatomegaly, splenomegaly, enlarged abdominal lymph nodes, raising suspicion of a round cell tumor in the spleen. His anemia effusion did not improve despite chemotherapy cytarabine administration. Erythroid precursor...
Several clinical studies have reported increased expression of osteopontin (OPN) in various types human cancer, including gastric cancer. However, the precise mechanisms underlying tumor development remain unclear. In present study, we investigated pathogenic roles OPN Helicobacter pylori-induced cancer development. Wild-type (WT) and knockout (KO) mice were treated with N-methyl-N-nitrosourea (MNU) infected H.pylori. Mice killed 50 weeks after treatment, stomach tissues assessed by...

The polymerase of avian influenza A virus (AIV) is a heterotrimer composed PB2, PB1, and PA. PB2 plays role in overcoming the host barrier; however, genetic prerequisites for to acquire mammalian pathogenic mutations have not been well elucidated. Previously, we identified prototypic that conferred non-replicative non-pathogenic traits PR8-derived recombinant when it was used infect mice. Here, demonstrated key amino acid (I66M, I109V, I133V, collectively referred as MVV) this increase...
Abstract A 12‐year‐old castrated male Shih‐Tzu dog was referred for uncontrolled glaucoma and uveitis with highly pigmented sclera, in both eyes (OU). On ophthalmic examination, the menace response, dazzle reflex pupillary light were negative OU. The intraocular pressure 27 mmHg right eye (OD) 70 left (OS) despite administration of antiglaucoma eyedrops. Ultrasound biomicroscopy revealed a closed ciliary cleft Ocular ultrasonography hyperechoic materials vitreous OU retinal detachment OS....
Age-associated molecular changes are deleterious and causally linked with aging may affect life span through diet.
To assess the characteristics of blebs formed after Ahmed glaucoma valve (AGV) surgery in dogs using ultrasound biomicroscopy (UBM) and to analyze their correlation with postoperative intraocular pressure (IOP).
Here, we examined the effects of BMP signaling pathway inhibitor LDN-193189 on pluripotency porcine embryonic stem cells (ESCs) in absence feeder using molecular and transcriptomic techniques. Additionally, some extracellular matrix components ESC were evaluated to develop an optimized sustainable feeder-free culture system for ESCs. Feeder found play important role supporting ESCs by blocking trophoblast mesodermal differentiation through inhibition pathway. treatment with LDN-193189,...
A six-year-old castrated male Maltese dog presented to a private animal clinic with mass on the dog's lower lip without any other clinical signs. The (3 × 2 cm) was whitish and grossly well circumscribed, histopathological examination revealed that composed of normal cartilage tissue surrounded by fibrous connective tissues. Based gross findings, histopathology anatomical location mass, first diagnosis cartilaginous choristoma in made.
A 3.9-year-old female African pygmy hedgehog (Atelerix albiventris) had a firm, tan-colored mass with an uneven surface arising from the mandibular salivary gland. histopathologic examination revealed that was composed of neoplastic proliferation epithelial and spindle cells. The cells showed positive for vimentin, smooth muscle actin, calponin cytokeratin 14 and, negative 19, suggesting were derived myoepithelial Based on histological findings immunohistochemistry results, diagnosed as...
Here, we report pig embryonic stem cells (ESCs) originating from parthenogenetic blastocysts which were developed 2-cell embryos micro-injected with porcine OCT4 reporter system cultured in previous reported chemically defined culture media. The ESCs expressed pluripotency markers and fluorescent signals produced by system. Also, they capable of forming teratomas following subcutaneous injection into nude mice. Since enables the non-destructive classification condition live pluripotent...

Abstract Background A 10‐year‐old castrated male Maltese dog was presented with chronic swelling that had been present for at least 5 years in the medial canthus of right eye (OD). Objectives To describe treatment outcome dacryops dacryolithiasis. Methods Bilateral patency nasolacrimal system confirmed by flushing both upper and lower puncta. Ocular ultrasonography revealed a well‐defined, oval‐shaped, heterogeneous mass several hyperechoic foci. Dacryocystorhinography no connection between...
Two Whooper swan (Cygnus cygnus) died after suffering from pododermatitis, lethargy, and ataxia; necropsy was performed.Grossly, the liver swollen firm.The kidney spleen were also enlarged a pale tan color.On histopathologic examination with Congo red staining, amyloidosis noted in liver, spleen, kidney.In addition, marked osseous metaplasia present liver.Based on these results, systemic involving diagnosed.Study results indicate that an inflammatory reaction associated pododermatitis had...
