In rubber hand illusion, visual information affects tactile information, whereas in the mirror box illusion, visual information has the opposite effect. However, its underlying mechanisms are not fully understood. As one of the reasons, non-invasive neuroimaging techniques, such as functional magnetic resonance, positron emission tomography, and electroencephalography, often fail to detect complex and fragile responses in the sensory-motor cortex.

Near-infrared photoimmunotherapy as a complementary modality to in situ vaccine in a preclinical pancreatic cancer model.

Biochem Biophys Res Commun

December 2024

Department of Gastroenterology and Hepatology, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

Pancreatic cancer is one of the most refractory malignancies. In situ vaccines (ISV), in which intratumorally injected immunostimulatory adjuvants activate innate immunity at the tumor site, utilize tumor-derived patient-specific antigens, thereby allowing for the development of vaccines in patients themselves. Near-infrared photoimmunotherapy (NIR-PIT) is a novel therapy that selectively kills cancer cells exclusively in the NIR-irradiated region.

  • Metaplastic thymoma (MT) is a rare type of thymic tumor that has a specific genetic fusion (YAP1::MAML2), similar to skin tumors called poromas.
  • Recent studies revealed that MT lacks YAP1 C-terminus expression, but the expression of YAP1 N-terminus in MT and other thymic epithelial tumors (TETs) needed further exploration.
  • In an examination of 14 MT cases, it was found that MT consistently showed a distinct staining pattern (YAP1[N]-positive, YAP1[C]-negative), while other TETs like type B3 thymoma exhibited variable staining, highlighting the need for more research on YAP1's role

Article Synopsis
  • A study in Japan compared outcomes of patients with venous thromboembolism (VTE) treated with warfarin (2010-2014) versus direct oral anticoagulants (DOACs) (2015-2020) from two multicenter registries.
  • The use of DOACs skyrocketed from 2.6% in the warfarin era to 79% in the DOAC era, leading to a significant reduction in the 5-year recurrence rate of VTE (10.5% to 9.5%).
  • However, the incidence of major bleeding remained similar between the two eras, indicating that while DOACs may reduce VTE recurrence, concerns about bleeding risks continue.
