Pulmonary Arterial Remodeling and RV Afterload
2026-09-12
The reference study combines subject-specific one-dimensional fluid–structure interaction modeling with hemodynamic measurements, tissue mechanics, histology, and x-ray micro-tomography to separate how pulmonary arterial remodeling increases right ventricular afterload. Its central finding is that increased distal resistance most strongly raises maximum main pulmonary artery pressure, whereas reduced arterial compliance substantially alters characteristic impedance.

CD163+ Macrophages and Granulosa Cell Apoptosis in PCOS
2026-09-11
Ye et al. connect macrophage-associated CD163 signaling with granulosa cell injury in polycystic ovary syndrome (PCOS) using transcriptomic analysis, patient serum measurements, a DHEA-induced mouse model, and macrophage–granulosa cell co-culture. The study supports a model in which inflammatory macrophage activity and soluble CD163 accompany granulosa cell apoptosis, while also defining important limits for interpreting CD163 as a causal therapeutic target.

Electrical Stimulation Improves Nanoparticle Uptake
2026-09-08
Wang and colleagues show that alternating-current electrical stimulation increases magnetic nanoparticle endocytosis in several cancer-cell models, primarily through macropinocytosis associated with reduced F-actin and elevated intracellular Ca2+. The approach improves both magnetic-hyperthermia activity and MRI signal intensity, suggesting a relatively simple, particle-agnostic strategy for enhancing nanoparticle-based cancer workflows.

Spatial Lipid Changes in Postoperative Cognitive Dysfunction
2026-09-05
The reference study combines spatial mass spectrometry imaging with behavioral, molecular, and ultrastructural analyses to map hippocampal lipid abnormalities after cardiopulmonary bypass in rats. Its findings connect CA1 lipid accumulation and altered iPLA2/SPT signals with synaptic injury and show that DHA or Myriocin treatment can partially normalize metabolic and cognitive outcomes.

Predicting Major Bleeding During Extended Anticoagulation
2026-09-04
This prospective multinational cohort study evaluated bleeding-risk prediction in patients with unprovoked or weakly provoked venous thromboembolism receiving extended anticoagulation. Modified ACCP, VTE-BLEED, and HAS-BLED scores identified higher-risk patients, while the simpler CHAP model used continuous creatinine, hemoglobin, age, and antiplatelet exposure but still requires external validation.

Tankyrase Inhibition and Hippo Signaling in HCC
2026-09-03
Jia et al. showed that XAV-939 and G007-LK inhibit hepatocellular carcinoma cell growth while reducing YAP activity through stabilization of the angiomotin-like proteins AMOTL1 and AMOTL2. The study expands tankyrase biology beyond Wnt signaling and provides a mechanistic basis for evaluating Hippo-pathway responses in liver cancer models.
