Role of qualitative contrast-enhanced ultrasound in the diagnosis of malignant breast lesions.

Background: Carcinoma breast is the commonest cancer among women. Various authors have studied breast cancer with Contrast-Enhanced Ultrasound (CEUS) with promising results. Despite promising results, the additional cost of post-processing software limits its availability.

ATR-mediated CD47 and PD-L1 up-regulation restricts radiotherapy-induced immune priming and abscopal responses in colorectal cancer.

Radiotherapy (RT) of colorectal cancer (CRC) can prime adaptive immunity against tumor-associated antigen (TAA)-expressing CRC cells systemically. However, abscopal tumor remissions are extremely rare, and the postirradiation immune escape mechanisms in CRC remain elusive. Here, we found that irradiated CRC cells used ATR-mediated DNA repair signaling pathway to up-regulate both CD47 and PD-L1, which through engagement of SIRPα and PD-1, respectively, prevented phagocytosis by antigen-presenting cells and thereby limited TAA cross-presentation and innate immune activation.

Catastrophic Anti-Phospholipid Syndrome in Systemic Lupus Erythematosus: A Tsunami in the Ocean.

Unlabelled: Antiphospholipid anti body syndrome is an autoimmune disorder characterized by arterial or venous thrombosis and/or pregnancy morbidity with foetal deaths or abortions in the presence of antiphospholipid antibodies. Catastrophic antiphospholipid antibody syndrome (CAPS) is an accelerated form of disease with rapid involvement of multiple organ systems often posing a diagnostic challenge. There is a paucity of literature on the presentations of CAPS owing to the orphan nature of the disease.

Cases of catastrophic anti-phospholipid syndrome in systemic lupus erythematosus: An experience.

Anti-phospholipid syndrome is an autoimmune disorder characterized by episodes of arterial and/or venous thrombosis and/or pregnancy morbidity in the presence of anti-phospholipid antibodies. Catastrophic anti-phospholipid syndrome is an accelerated form of the disease with rapid involvement of multiple organ systems often posing a diagnostic challenge. There is a paucity of literature on the myriad presentations of catastrophic anti-phospholipid syndrome owing to the orphan nature of the disease.
