Long‐Term Follow‐Up of Superior Vena Cava–Right Atrium Spontaneous Conduction Block Line Durability Using the White‐Line Approach of Extended Early Meets‐Late Rate Tools

Journal of Arrhythmia
Background Superior vena cava (SVC)–right atrium (RA) spontaneous conduction block occurs in some patients. We demonstrated a novel approach for SVC isolation using visualization of the SVC–RA conduction block line as a white line with the extended early

Histological Analysis of Cryopreserved Venous Allografts Used for Liver Transplantation and Hepato‐Biliary‐Pancreatic Surgery

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background Cryopreserved venous allografts, which we pioneered in 1999 for use in living donor liver transplantation and hepato‐biliary‐pancreatic surgery, are widely used and are believed to preserve vascular architecture with minimal anticoagulation or immunosuppression requirements and patency comparable to autologous grafts.

Integrating Environmental Perceptions and Value Cognition to Understand Farmers' Livelihood Capacity: Evidence From a Rocky Desertification Area in China

Land Degradation &Development, EarlyView.
ABSTRACT Rocky desertification poses a serious threat to the sustainable development of karst regions. Large‐scale ecological restoration projects for ecologically fragile areas not only improve regional ecological quality but also affect farmers' perception of rocky desertification control (PRDC) and value cognition.

Bilateral Absence of the Superior Vena Cava

Case Reports in Cardiology, 2012
Bilateral absence of the superior vena cava (SVC) is a very rarely detected, mainly asymptomatic congenital vascular anomaly. Though usually innocent, this anomaly may complicate cardiothoracic surgery and certain procedures like central venous catheter ...

Essential oils as bioherbicides: effects of orange and citronella oils on weed germination and early growth

Pest Management Science, EarlyView.
Essential oils from orange and citronella showed dose‐dependent inhibition of weed germination and early growth, highlighting their potential as bioherbicides and sustainable tools for integrated weed management. Abstract BACKGROUND Increasing selection of herbicide‐resistant weed biotypes has intensified the search for alternatives to the intensive ...
