A 40.68‐MHz Active Rectifier Using PLL and PWM Control of DC‐DC Converter for ON/OFF Delay Compensation

International Journal of Circuit Theory and Applications, EarlyView.
A ramp‐based phase‐locked loop (RPLL) active rectifier operating at 40.68 MHz compensates switching delay variations to improve phase alignment. The proposed architecture achieves 90.3% peak power conversion efficiency and 98.0% voltage conversion ratio for high‐frequency wireless power transfer in implantable medical devices.

Black phosphorus‐based photothermal disruption of cancer‐associated fibroblast barriers and tumor‐associated macrophage targeting to enhance anti‐PD‐L1 immunotherapy in triple‐negative breast cancer

Interdisciplinary Medicine, EarlyView.
MBB modulates the TNBC tumor microenvironment by targeting TAM/CXCL1 and facilitates anti‐PD‐L1 therapy by disrupting CAF barriers via its photothermal effect. This combined strategy subsequently enhances the efficacy of PD‐L1 mAb and suppresses TNBC progression, metastasis, and recurrence.

Targeting eIF5A combats breast cancer progression by ClpP‐dependent mitochondrial oxidative stress

Interdisciplinary Medicine, EarlyView.
This study identified the eIF5A‐ClpP axis as a key driver of breast cancer progression. Targeting eIF5A suppresses tumor growth by inducing ClpP‐dependent mitochondrial oxidative stress, revealing a novel therapeutic vulnerability. Abstract Breast cancer (BC) poses a persistent global health challenge, necessitating new therapeutic targets.

Australia's Three System Approach to Mammographic Image Quality Assessment

Journal of Medical Radiation Sciences, EarlyView.
Mammographic image evaluation in Australia remains constrained by the use of fragmented, subjective, and largely unevaluated systems. The continued use of the Perfect (P), Good (G), Moderate (M), Inadequate (I) (PGMI) image evaluation system (IES) framework despite concerns around its validity and reliability reflects a perceived practical utility and ...

Diagnosis and Management of Prenatal Hereditary Pyropoikilocytosis

Prenatal Diagnosis, EarlyView.
ABSTRACT Hereditary pyropoikilocytosis (HPP) is a severe hemolytic anemia caused by variants in SPTA1, SPTB, and EPB41. These weaken horizontal interactions in the erythrocyte cytoskeleton, causing membrane fragmentation and splenic sequestration. It will readily cause fetal anemia and often hydrops fetalis. Prenatal diagnosis requires first ruling out
