Transcatheter Repair of Sinus Venosus Defect Using a 12‐zig Covered Cheatham‐Platinum Stent in Large Superior Vena Cava—Right Atrium Junctions: Early Multicenter Experience

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Sinus venosus defect (SVD) is a rare congenital heart anomaly characterised by an abnormal communication between the atria, often associated with partial anomalous pulmonary venous connection (PAPVC). Traditional surgical repair carries significant risks, prompting exploration into less invasive transcatheter approaches.

Modeling and experimental validation of bolt–grout bond–slip behavior for deep underground excavation support

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Recovery Factor of Pure Helium Injection in Depleted Gas Reservoirs and Its Influencing Factors

open access: yesEnergy Science &Engineering, EarlyView.
This study employs compositional numerical simulation to systematically investigate the effects of injection rate, production rate, storage duration, and injection‐production scheme on pure helium recovery in depleted gas reservoirs. Low injection rates reduce viscous fingering while high production rates maximize near‐wellbore helium extraction ...

Clinical and research applications of synthetic bone substitutes in equine veterinary medicine: A systematic review

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Bone grafting in equine medicine offers a promising contribution to treating orthopaedic developmental diseases and chondral, osteochondral and segmental bone defects. Among grafts, synthetic bone substitutes—alloplastics—show favourable biological properties addressing numerous limitations presented by autografts, xenografts and ...

Ulnocarpal stabilization in the management of comminuted fractures distal end radius

open access: yesIndian Journal of Orthopaedics, 2009
Malunion due to progressive radial collapse during healing is a common complication following comminuted fracture distal radius treated by conventional methods. Many treatment modalities have been described with their own merits and demerits. Stabilization of ulnocarpal articulation is an effective method to prevent radial collapse during healing, and ...

Mind the Gap: Predictors of Osteoporosis Treatment Following Fragility Fracture in Parkinsonism

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Fracture risk is increased in Parkinson's yet this risk is often not addressed. Objectives Our objective was to study the extent to which osteoporosis was treated, and predictors of treatment in a large representative cohort with parkinsonism.

Mammalian Osteoderm Ultrastructure in the Armored Acomys Spiny Mouse Tail

open access: yesSmall, EarlyView.
The ultrastructure of armored platelets – termed osteoderms – in the tail skin of Acomys cahirinus spiny mice is characterized using 2D and 3D microscopy methods. The imbricated structure is composed of calcium phosphate biomineral and has select structural elements that are bone‐like and tooth‐like in nature.
