Article Abstract
Assessment of spleen size using the ultrasonography has become a standard practice in human. However, the assessment is not established method in experimental animals. To establish the index to assess the spleen size using ultrasonography, we measured the cross-section image of rabbit spleen during endotoxin shock. The image of the cross-section was appeared as triangle, and the height of the triangular image was defined as the spleen index. This spleen index showed strong correlation with the spleen weight. In conclusion, this method is suitable for observation of changes in rabbit spleen size and may reduce the number of rabbit in the longitudinal studies.
Introduction: Depression negatively impacts the prognosis of various cancers, including lung cancer, by influencing antitumor immune responses and impairing immune cell function. Antidepressants may modulate the tumor immune microenvironment, enhancing immunotherapy efficacy. However, the specific mechanisms remain unclear.
Introduction: Primary bone marrow diffuse large B-cell lymphoma is a rare clinical entity, and the "bone marrow-liver-spleen" type of diffuse large B-cell lymphoma is rarer, with only a few published cases in literature. Though bone marrow-liver-spleen-type diffuse large B-cell lymphoma has unique presentations such as fever, cytopenias, and hemophagocytic lymphohistiocytosis, no cases with cold autoimmune hemolytic anemia have been reported.
Case Presentation: A 39-year-old Sri Lankan woman, previously healthy, presented with shortness of breath, productive cough, and fever for 4 days.

Purpose: The purpose of this study was to investigate the therapeutic efficacy of the combination of microwave ablation (MWA) with immune checkpoints blockade and TLR9 stimulation in the treatment of non-small cell lung cancer (NSCLC) using the C57BL/6 tumor-bearing mice model.
Materials And Methods: Tumor-bearing mice were treated with MWA, programmed cell death protein1 blockade (PD-1) plus MWA (MWA + P), TLR9 agonist CpG ODNs and MWA (MWA + C), PD-1 blockade and CpG ODNs (P + C), MWA plus PD-1 blockade and CpG ODNs (MWA + P + C), or untreated. Survival time was evaluated with the Kaplan-Meyer method comparing survival curves by log-rank test.
Background: Extracellular vesicles (EVs) and extruded nanovesicles (ENVs) are promising nanovesicles (NVs) for drug delivery. However, the application of these NVs is strongly hindered by their short half-life in the circulation. Macrophages (Mφs) in the liver and spleen contribute to the rapid depletion of NVs, but the underlying mechanism is unclear.

Background: The spleen is a key organ in preventing pneumococcal infection, especially in patients with immunocompromised condition such as those with cancer. Previous studies have shown that a small spleen volume in pneumococcal pneumonia patients is associated with severe disease course. However, it is unknown whether a small spleen increases risk of pneumococcal infection.
