Article Abstract
Background: Combination chemotherapy is used to treat advanced thymic carcinoma; however, the effects are insufficient.
Methods: Previously untreated patients with unresectable locally advanced thymic carcinoma received two cycles of 80 mg/m /day S-1 orally on days 1-14 plus 60 mg/m /day cisplatin intravenously on day 1, and concurrent radiotherapy (60 Gy).
Results: Three patients were enrolled into the study. Toxicity and survival were assessable in all patients, but the treatment response was only assessable in one patient. The study was terminated because of poor case recruitment. The patients' characteristics were as follows: male/female = 2/1; PS 0/1 = 2/1; median age (range) = 59 (55-72); and stage III/IV = 2/1. The patient in which the treatment response was assessed exhibited SD (response rate: 0%). In both nonevaluable cases, the second course of chemotherapy was judged to be post-protocol treatment because it was delayed by ≥14 days, but a CR and PR were achieved after the end of the study, respectively. G4 leukopenia/neutropenia and G3 febrile neutropenia occurred in one patient each (33%). The median time to tumor progression was 17.6 months, and the 1-, 2-, 3-, and 4-year survival rates were 67, 33, 33, and 33%, respectively. The median overall survival time was not reached, and the 1-, 2-, 3-, and 4-year survival rates were 100, 67, 67, and 67%, respectively.
Conclusions: Although it was difficult to recruit patients, there was a long-term survivor >4 years who appeared to have achieved a CR, indicating that such chemoradiotherapy may be effective against locally advanced thymic carcinoma.

Asthma is a complex clinical syndrome characterized by airway inflammation that can cause variable, usually reversible airway obstruction and bronchial hyperreactivity. This illness has a spectrum from intermittent to persistent that has mild, medium or severe intensity. As our understanding of the underling inflammatory pathway grows, so too does our catalogue of advanced treatments (such as monoclonal antibodies), opening the path for treatment individually curated for patients.

Chickens are renowned as a model for embryogenesis but have also been responsible for crucial advances in virology, cancer research and immunology. However, chickens are best known as a major source of animal protein for human nutrition, with roughly 80 billion chickens alive each year supplying meat and eggs, the vast majority part of a global poultry industry. As a result, avian immunology been studied intensively for over 60 years, and it has become clear that a major genetic locus in chickens determining resistance to infectious disease and response to vaccines is the major histocompatibility complex (MHC).

Glioblastoma multiforme (GBM) is a malignant primary brain tumor categorized as a Grade 4 astrocytic glioma by the World Health Organization (WHO). Some of the established risk factors of GBM include inherited genetic syndromes, body mass index, alcohol consumption, use of non-steroidal anti-inflammatory drugs (NSAIDs), and therapeutic ionizing radiation. Vascular anomalies, including local and peripheral thrombosis, are common features of GBM.

Background: Despite advances in immunosuppressive therapies, chronic rejection and immunosuppression-related complications remain significant challenges in transplantation. Developing transplantation tolerance through thymus transplantation may offer a solution. This paper details our technique for procuring and transplanting porcine vascularized thymic lobes (VTL), which can be utilized to study and research allogeneic and xenogeneic transplantation models in large animals.

Introduction: Thymic epithelial tumors (TETs) are rare neoplasms typically located in the anterior mediastinum. While immune checkpoint inhibitors (ICIs) show promise for advanced or refractory TETs, their clinical application is hindered by heterogeneous responses across TET subtypes, lack of reliable predictive markers, and the risk of immune-related adverse events (irAEs).
Methods: We analyzed TCGA, GEO, and GTEx databases to identify differentially expressed genes (DEGs) among three TET subtypes.
