Abstract Primary cardiac lymphoma is a highly rare type of malignant tumor that originates from the lymphoid tissue within the heart or pericardium. Surgical treatment is the primary method for obtaining pathological results and relieving obstructions, and chemotherapy is the main method for disease control. We present a case of a 67-year-old woman diagnosed with primary cardiac lymphoma, presenting with shortness of breath and bilateral lower extremity edema after activity.

Abstract Negative feedback is a well-known mechanism for attenuating noise and enhancing robustness in biological systems. When coupled with cell-cell signaling, it provides a strategy for achieving population-level control in multicellular systems. While cell-cell signaling alone tends to reduce cell-to-cell variability by averaging fluctuations across cells, its interplay with negative feedback can produce contrasting effects on noise regulation at single-cell and population levels.
