A newly designed arterial monitoring and perfusion cannula for cardiopulmonary bypass eliminates the need for cannulation of a peripheral artery for pressure monitoring. The double-lumen cannula is designed as follows: the large central lumen (12 to 26f) acts as the arterial inflow conduit from the pump oxygenator, while a second, smaller lumen (18 gauge)constructed in the wall of the first cannula acts as the pressure-monitoring port and the source for blood sampling and drug infusion. This monitoring/perfusion cannula has been used succesfully in more than 250 clinical patients in a variety of settings--total cardiopulmonary bypass, left heart bypass, and when multiple arterial inflow lines were necessary (as in aortic arch replacement). Use of this cannula is advantageous in the infant and pediatric patient or in the emergency setting, when insertion of a peripheral arterial line can be difficult. Used in conjunction with a Doppler system, the cannula provides accurate, dependable blood pressure monitoring.

Site-directed mutagenesis is a fundamental tool indispensable for protein and plasmid engineering. An important technological question is how to achieve the efficiency at the ideal level of 100%. Based on complementary primer pairs, the QuickChange method has been widely used, but it requires significant improvements due to its low efficiency and frequent unwanted mutations.

Owing to critical policy significance, a growing body of literature has been predominantly concentrating on the social welfare benefits brought by green finance (GF) initiatives. However, there is a paucity of research that quantifies the economic costs of GF initiatives on carbon reduction, raising the increasing concerns about the irreconcilable climate-economy trade-offs. To end this, the present study systematically investigates the influence of GF initiatives on the carbon-related marginal abatement cost (MAC) using two competing hypotheses: regulatory versus technical effects.

Background: Huangkui capsule (HKC), a Chinese patent medicine, is clinically used for treating diabetic nephropathy. However, the core disease-specific biomarkers and targets of type 2 diabetic nephropathy (T2DN) and the therapeutic mechanism of HKC are not fully elucidated.
Purpose: This study aimed to investigate the therapeutic effects and underlying molecular mechanisms of HKC for T2DN.

Electronic address:
Aim: This integrative review explores the transition to practice experiences of graduate nurses working in either acute or non-acute paediatric settings across different countries.
Background: Graduate nurses frequently experience feelings of inadequacy, uncertainty, increased accountability, and workload pressures during their transition, particularly in paediatric settings. However, research specifically examining their experiences in paediatric healthcare is limited, with most studies focusing on broader nursing contexts.
