Percutaneous Transaxillary Access for Large‐Bore Cardiovascular Interventions: Evidence, Technique, and Complication Management

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Percutaneous transaxillary access is an established alternative to transfemoral large‐bore arterial access for transcatheter structural heart interventions and mechanical circulatory support (MCS). Although useful for overcoming hostile iliofemoral anatomy and providing prolonged support and patient mobilization in case of MCS, the axillary ...

A comparison between cannulated and non-cannulated cancellous screws used in the fixation of a simulated femoral neck fracture - a finite element study

, 2016
Previous studies have been done on the performance of different screw designs and configurations. These are based on the pull-out strength of the screws and the best fixation based on load, stiffness and displacement characteristic. However, there is not

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, EarlyView.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...

Anterior cingulate cortex neuron subtypes differentially regulate seizures

Epilepsia, EarlyView.
Abstract Objective This study aimed to investigate the regulatory roles of distinct neuronal subtypes within the anterior cingulate cortex (ACC) in acute seizures and to identify cell type‐specific mechanisms underlying seizure modulation in this region. Methods Acute seizure models were established in mice via pentylenetetrazol injection.
