Post-pericardiectomy ECMO for constrictive pericarditis: a case series and literature review.

Background: Pericardiectomy is the curative treatment for constrictive pericarditis, yet postoperative low cardiac output syndrome (LCOS) may occur. The application of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in post-pericardiectomy refractory LCOS has limited case reports, and its effectiveness and safety remain unclear. This study aims to provide evidence for the effectiveness of ECMO in treating post-pericardiectomy refractory LCOS.

Kidney Injury under Diminished Pulsatile Flow Induced by V-A ECMO in Sheep.

Extracorporeal membrane oxygenation (ECMO) is commonly used for critically ill patients and associated with high rates of kidney injury and mortality. This study aimed to assess the impact of diminished pulsatile flow induced by veno-arterial ECMO (V-A ECMO) on kidney structure and function. Ten healthy sheep were divided into two groups (n=5 each) to compare diminished pulsatile flow induced by V-A ECMO with normal pulsatile flow under veno-venous ECMO (V-V ECMO) over 7 days.

Herein, Cu-foam-supported CuO nanowire arrays covered with CuS nanosheet substrates (Cu/CuO/CuS) are adopted as efficient photoelectrodes for photorechargeable lithium-ion batteries (PR-LIBs). The assembled PR-LIB exhibits remarkable solar energy conversion efficiency alongside superior lithium storage capabilities. Without an electrical power supply, the photocharged PR-LIB sustained a discharge process for 63.

Response of soil moisture to rainfall following deep soil drying in China's hilly loess lands.

Deep soil drying is a physical soil phenomenon that has become increasingly characteristic to artificial afforestation on China's Loess Plateau. Current research is largely short of conclusive reports on soil moisture recovery following deep soil drying in afforested lands. In this study, a 10-m deep underground column was constructed at Pengyang Experimental Station in Ningxia.

A modified low-priming cardiopulmonary bypass system in patients undergoing cardiac surgery with medium risk of transfusion: A randomized controlled trial.

Objectives: The FUWAI-SAVE system is a modified low-priming cardiopulmonary bypass (CPB) system. The study aimed to explore whether the FUWAI-SAVE system can reduce the perioperative blood transfusion and its impact on other postoperative complications during cardiac surgery.

Metohds: This study was a single-center, single-blind, randomized controlled trial, registered at the Chinese Clinical Trial Registry (identifier: ChiCTR2100050488).

A novel machine learning prediction model for metastasis in breast cancer.

Background: Breast cancer (BC) metastasis is the common cause of high mortality. Conventional prognostic criteria cannot accurately predict the BC metastasis risk. The machine learning technologies can overcome the disadvantage of conventional models.

Triazole-modified Ru-carbene complexes: A valid olefin metathesis pre-catalyst for dynamic covalent chemistry via C=C bond formation.

The 1,2,3-triazole coordinated ruthenium carbene complexes (TA-Ru) were reported for the first time as a new class of modified Grubbs catalyst to achieve challenging olefin metathesis at higher temperatures without catalyst decomposition. Previously reported N-tethered Ru-carbene complexes all suffered from rapid isomerization, causing significantly reduced catalyst reactivity. These new TA-Ru complexes hold the active -dichloro conformation even at 80 °C, allowing effective olefin metathesis for challenging substrates.

Predictive value of combining leucocyte and platelet counts for mortality in ST-segment elevation myocardial infarction patients after percutaneous coronary intervention treatment in Chinese population: a retrospective cohort study.

Objective: Risk stratification is challenging in patients with acute ST segment elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PCI). We investigated the prognostic value of a novel score system combining leucocyte and platelet counts (COL-P) scores for in-hospital and long-term adverse outcomes.

Design: This was a retrospective cohort study of patients with STEMI.

Asymmetric Hydrative Aldol Reaction (HAR) via Vinyl-Gold Promoted Intermolecular Ynamide Addition to Aldehydes.

Herein, we reported an intermolecular asymmetric hydrative aldol reaction through vinyl-gold intermediate under ambient conditions. This tandem alkyne hydration and sequential nucleophilic addition afforded a "base-free" approach to β-hydroxy amides with high efficiency (up to 95 % yields, >50 examples). Vinyl gold intermediate was applied as reactive nucleophile and Fe(acac) was used as the critical co-catalyst to prevent undesired protodeauration, allowing this transformation to proceed under mild conditions with good functional group tolerance and excellent stereoselectivity (>20 : 1 d.

Fabrication of Poly(ε-caprolactone)-embedded Lignin-Chitosan Nanocomposite Porous Scaffolds from Pickering Emulsions.

Poly(ε-caprolactone) (PCL)-incorporated lignin-chitosan biomass-based nanocomposite porous scaffolds have been effectively prepared by templating oil-in-water Pickering high internal phase emulsions (HIPEs). PCL is dissolved in oil and chitosan and lignin nanoparticles originate in water. The continuous phase of the emulsions is gelled by cross-linking of chitosan with genipin and then freeze-dried to obtain porous scaffolds.

Transcriptomic Profiling of circRNAs in rat Hippocampus after Deep Hypothermic Circulatory Arrest.

Neurologic abnormalities occurring after deep hypothermic circulatory arrest (DHCA) remain a significant concern. However, molecular mechanisms leading to DHCA-related cerebral injury are still ill-defined. Circular RNAs (circRNAs) are a class of covalently closed non-coding RNAs and can play important roles in different types of cerebral injury.

Transcriptomic Establishment of Pig Macrophage Polarization Signatures.

Macrophages are the foremost controllers of innate and acquired immunity, playing important roles in tissue homeostasis, vasculogenesis, and congenital metabolism. In vitro macrophages are crucial models for understanding the regulatory mechanism of immune responses and the diagnosis or treatment of a variety of diseases. Pigs are the most important agricultural animals and valuable animal models for preclinical studies, but there is no unified method for porcine macrophage isolation and differentiation at present; no systematic study has compared porcine macrophages obtained by different methods.
