Article Abstract

Splenic malignancies are reported in 30%-76% of dogs presenting with splenic masses, and splenectomy is the cornerstone in their management. However, long term prognosis is guarded due to the high rates of distant metastases reported both for HSA and nonangiogenic nonlymphomatous sarcomas. Metastases from splenic tumors usually occur to regional lymph nodes, liver, omentum, and lungs. These case series aim to describe 2 cases of splenic neoplasia with gastric involvement and report the surgical technique and outcomes associated with the condition. Two mixed-breed dogs were referred for a splenic mass and underwent explorative celiotomy. In both cases, the splenic mass was firmly attached to the gastric wall, and splenectomy with concurrent partial gastrectomy was thus performed. In case 1, liver lobectomy due to a hepatic mass was also performed. In case 2, the regional nodes were also excised due to lymphoadenomegaly. Both dogs recovered uneventfully from surgery and were discharged from the hospital at 72 and 96 hours. Histopathological examination was costent with splenic undifferentiated sarcoma and hepatic adenocarcinoma in one dog. The other dog had a diagnosis of malignant fibrous histiocytoma with nodal metastases. Neoplastic invasion of the stomach was histologically confirmed in both dogs. Adjuvant chemotherapy was refused, and both dogs were euthanized due to tumor progression at 71 and 58 days, respectively. According to our results, splenectomy with concurrent gastrectomy is feasible in dogs with splenic tumours involving the gastric wall. However, long term prognosis is poor, as previously reported for metastatic splenic sarcomas.

Introduction: Klippel-Trenaunay Syndrome (KTS) is a rare congenital condition characterized by vascular malformations, bone abnormalities, and limb overgrowth. The genetic basis of KTS is not fully understood, and the diagnosis relies on clinical features. Its clinical spectrum includes several neurosurgical diagnoses, such as cavernous hemangiomas, arteriovenous fistulas, and Chiari I malformation.

Introduction: Immunogenicity continues to be a challenge for development and clinical utility of monoclonal antibodies, and there are gaps in our current ability to prevent anti-drug antibody development in a safe and antigen-specific manner.

Methods: To mitigate immunogenicity of monoclonal antibodies administered subcutaneously, O-phospho-L-serine (OPLS)-the head group of the tolerance-inducing phospholipid, phosphatidylserine-was investigated as an immunoregulatory adjuvant.

Results: Formulations of adalimumab, trastuzumab or rituximab with OPLS showed reduction in relative immunogenicity in mice compared to vehicle formulations, indicated by reduced anti-drug antibody development and significant reductions in CD138+ plasma cell differentiation in bone marrow.

The study comprehensively investigated the therapeutic potential of triterpenoid saponin extract (GST), encompassing its hepatoprotective, immunomodulatory, and anticancer activities. The study employed a Prednisolone (PRD)-induced immunosuppressed rat model to assess the hepatoprotective and immunomodulatory effects of GST. Using this model, GST was found to modulate haematopoiesis, improving RBC, platelet, and WBC counts, underscoring its potential in hematopoietic homeostasis.

NHC Key Laboratory of Public Nutrition and Health, National Institute for Nutrition and Health, Chinese Center for Disease Control and Prevention, Beijing 100050, China.

Objective: To explore the antitumor effect of Inonotus obliquus extract on 4T1 tumor-bearing mice in vivo and its possible mechanism.

Methods: 4T1 tumor-bearing mice model was established. After successful modeling, tumor-bearing mice were randomly divided into model control group, cyclophosphamide(CTX) positive group, and high, medium and low dose groups of Inonotus obliquus extract, with 10 mice in each group, which were administered continuously for 21 days.

The relationship between D-AA metabolic enzymes and cancer development remains unclear. We aimed to investigate this relationship using mice deficient in D-AA-related metabolic enzymes. We examined mice lacking these enzymes for approximately 900 days and the effects of altered D-AA metabolism on cancer development based on lifespan, pathological findings, and gene expression.
