Penile strangulation is an infrequent clinical condition that has widely been reported. It usually results following placement of a constriction device to enhance sexual stimulation. Early treatment is essential to avoid potential complications, including ischemic necrosis and autoamputation. We describe the use of a Large Orthopedic Pin Cutter to remove a metal penile constriction device in the Emergency Department (ED). This case report describes the relatively safe technique of using an instrument available in many hospitals that can be added to the physician's arsenal in the removal of metal constriction devices.

Many micro-particles including pathogens strongly adhere to hosts. It remains elusive how macrophages detach these surface-bound particles during phagocytosis. We show that, rather than binding directly to these particles, macrophages form unique β integrin-mediated adhesion structures at the cell-substrate interfaces, specifically encircling the surface-bound particles.

Early detection is crucial for preventing irreversible damage. The pupillary light reflex (PLR) has proven useful in glaucoma diagnosis, and mobile technologies like the AI-based smartphone pupillometer (AI Pupillometer) offer a promising solution for accessible screening.

BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) encompasses a group of disorders ranging from hyperplastic to malignant lymphoid proliferations in the post-transplant period owing to immunosuppression, often in the setting of EBV transformation. PTLD is a rare complication of immunosuppression that, like lymphomas, can have a variable presentation based on disease localization. We report a case of PTLD mass effect at the porta hepatis for the first time in the literature, resulting in hepatic artery stenosis (HAS) and common hepatic duct obstruction.

Sacubitril/valsartan (Sac/Val) belongs to the group of angiotensin receptor-neprilysin inhibitors and has been used for the treatment of heart failure (HF) for several years. The mechanisms that mediate the beneficial effects of Sac/Val are not yet fully understood. In this study we investigated whether Sac/Val influences the two proteolytic systems, the ubiquitin-proteasome system (UPS) and the autophagy-lysosomal pathway (ALP), in a mouse model of pressure overload induced by transverse aortic constriction (TAC) and in human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) treated with endothelin-1 (ET1) serving as a human cellular model of hypertrophy.

Physical models of cell motility rely mostly on cytoskeletal dynamical assembly. However, when cells move through the complex 3D environment of living tissues, they have to squeeze their nucleus that is stiffer than the rest of the cell. The lamin network, organised as a shell right underneath the nuclear membrane, contributes to the nuclear integrity and stiffness.
