PRIMARY PERCUTANEOUS INTERVENTION (PCI) IN A SAPHENOUS VEIN GRAFT

Pakistan Armed Forces Medical Journal, 2016
Occlusion and degeneration of saphenous vein grafts (SVGs) poses significant problems in patients who have undergone coronary artery bypass graft (CABG) surgery. In the first year post-CABG SVG occlusion rate is approximately 15%.

An Expertise Transfer Framework For Autonomous Surgical Assistance

Advanced Science, EarlyView.
This study introduces an expertise transfer framework for procedure‐spanning autonomous surgical assistance. By emulating expert logic through hierarchical perception, attention modeling, and knowledge graph‐based decision‐making, the system provides near‐expert surgical view assistance.

Examining the subcortical infarcts in the era of acute multimodality CT imaging

Frontiers in Neurology, 2016
Background: Lacunar infarcts have been characterized as small subcortical infarcts, resulting from in situ microatheroma or lipohyalinosis in small vessels.

No evidence that severity of stroke in internal carotid occlusion is related to collateral arteries [PDF]

, 2006
Background/AimThe neurological effects of internal carotid artery (ICA) occlusion vary between patients. The authors investigated whether the severity of symptoms in a large group of patients with ipsilateral or/and contralateral ICA occlusion at ...

Alkylating Agent–Induced FANCL Impairment Damages Pulmonary Arterial, Venous, and Microvascular Endothelial Cells and Predisposes to PAH/PVOD

Advanced Science, EarlyView.
This study establishes a novel cisplatin‐induced rat model of PAH/PVOD and identifies a conserved mechanistic axis—FANCL impairment, DNA damage accumulation, and endothelial dysfunction—triggered by cisplatin or mitomycin C across pulmonary arteries, veins, and microvessels.

Sustainable Hydrogel‐Forming Microneedle‐Reservoir Patches for Transdermal Delivery of Hydrophilic Macromolecules: Biopolymers, Green Manufacturing and Translation

Advanced Science, EarlyView.
Hydrogel‐forming microneedle (HFMN)‐reservoir patches provide a modular route for controlled transdermal delivery of hydrophilic biomacromolecules. The platform integrates skin‐barrier penetration, sustainable biopolymers, scalable green manufacturing, hydration‐driven transport, model‐cargo validation, and translational quality requirements.

Tumor‐Intrinsic HEXB Drives Endothelial‐To‐Mesenchymal Transition and Confers Resistance to Anti‐Angiogenic Therapy in Glioblastoma

Advanced Science, EarlyView.
This study elucidates how glioblastoma tumors develop resistance to anti‐VEGF therapy through endothelial‐to‐mesenchymal transition (Endo‐MT). The researchers identify a novel signaling pathway where tumor‐derived HEXB stabilizes HSP60 to drive this vascular reprogramming.

Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Mild neurological symptoms despite middle cerebral artery occlusion.

, 2004
BACKGROUND AND PURPOSE: Only a small percentage of stroke patients are treated with thrombolytic therapy. We sought to determine whether vessel occlusion in mild strokes represented a new target population for interventional therapy.
