Article Abstract
Human erythrocytes represent candidates of choice as carriers for a wide range of drugs due to their unique biophysical and physiological properties. In this study, we used a sonoporation device generating and monitoring acoustic stable cavitation without any addition of contrast or nucleation agents. The device was evaluated for bovine serum albumin (BSA) delivery into human erythrocytes. After determining the adequate hematocrit percentage compatible with the generation of stable cavitation, we determined the optimal sonoporation conditions allowing BSA delivery while preserving erythrocyte integrity. Our results demonstrate that stable cavitation allows efficient delivery of proteins into human erythrocytes with limited lysis of these cells. In conclusion, our study allowed for the development of a stable and regulated cavitation program and the establishment of sonoporation conditions suitable for intracellular protein delivery while maintaining erythrocyte integrity. Additional investigations are needed to move from the proof of concept to a larger-scale application.

Diabetic myonecrosis is an uncommon complication of poorly controlled diabetes mellitus. Usually, patients present with acute painful swelling of the affected muscles, mostly the quadriceps muscle of the thigh. We present the case of a 57-year-old male with type 2 diabetes mellitus who presented with progressive bilateral thigh pain and reduced movement.

Rationale: Myocardial infarction with nonobstructive coronary arteries (MINOCA) has diverse ischemic etiologies and has been defined by the absence of angiographically significant obstructive coronary artery disease. Blood transfusion has seldom been reported as a precipitating factor for MINOCA. Here, we present a rare case of transfusion-associated MINOCA in a young woman without underlying chronic conditions, aiming to raise clinical awareness of this uncommon yet important phenomenon and to explore its potential pathophysiological mechanisms.

Introduction: To evaluate the characteristics of patients who have undergone surgical operations due to brain abscess and to assess the risk factors for mortality and the outcomes.
Methodology: Patients who have undergone surgical operations due to brain abscess between January 2014 and January 2024 in our hospital were evaluated retrospectively. Patients were divided into 2 groups to determine poor outcome predictive factors.

Xenogeneic cell transplantation often faces significant immune rejection, even in immunodeficient animal models. Among residual immune components, macrophages can actively phagocytose transplanted human cells, posing a challenge to long-term engraftment. To address this, we developed a standardized in vitro assay to quantify macrophage-mediated phagocytosis of human versus rat red blood cells (RBCs).
