Comparative analysis of perioperative renal function in patients undergoing heart transplantation and left ventricular assist device implantation: a multicenter retrospective study.

Background: Renal function is a crucial factor affecting the prognosis of patients with end-stage heart failure (HF). The differential impacts of heart transplantation and left ventricular assist device (LVAD) implantation on renal function are unclear. Therefore, we compared the perioperative renal function changes in patients who underwent heart transplantation with that of patients who underwent LVAD implantation.

Editing a mushroom with high-digestibility using a novel endo-N-acetyl-β-D-glucosaminidase.

Fungi comprise approximately 2 % of the Earth's biomass; however, the human gastrointestinal tract has a limited capacity to digest fungal biomass. In this study, a novel endo-N-acetyl-β-D-glucosaminidase, Endo CM, was characterized in the mushroom-forming fungus Cordyceps militaris, where it plays a role in maintaining the integrity of the fungal cell wall. Through gene editing, the Endo CM promoter was engineered to remove the binding site of the CmCreA carbon catabolite repressor, and the transformant was named CmT.

Monitoring investigation on impact of pile-based PV modules on several typical environmental elements in coastal mudflat intertidal zone.

With the construction of large photovoltaic modules in the intertidal zone, their impact on the environment has attracted people's attention. The paper took the first large-scale power generation project of "fishery-PV complementary" in the coastal mudflat intertidal zone of China as the research object and studied several typical environmental factors through on-site monitoring. The study results indicate that the average and maximum wind speeds in non-PV areas are more than twice that of PV areas.

An efficient direct electrolysis method for the synthesis of 1,1,1,3,3,3-hexafluoroisopropyxy substituted imidazo[1,2-]pyridines.

Electrochemical oxidative cross-dehydrogenative-coupling (CDC) is an ideal strategy to conduct the C3-alkoxylation of imidazo[1,2-]pyridine, but it remains a challenge owing to limitation imposed by the use of alkyl alcohols and carboxylic acids. Herein, we report a mild and efficient 2-electrode constant-potential electrolysis of imidazo[1,2-]pyridine with hexafluoroisopropanol (HFIP) to produce various imidazo[1,2-]pyridine HFIP ethers. Mechanistic studies indicated that the electrooxidation reaction might involve radical coupling and ionic reaction.

Prognostic Value of D-Dimer in Acute Type A Aortic Dissection and Intramural Hematoma: Observations from the Acute Aortic Syndrome Group of the Registry of Acute Non-Traumatic Chest Pain in China.

Background: Acute type A aortic dissection (AAD) and acute type A intramural hematoma (AIMH) are life-threatening conditions with high mortality rates, and prognostic indicators are critical for guiding urgent treatment decisions.

Feeding- and Light-Cycle Synergistically Regulate Mouse Blood Pressure Daily Rhythm via -Dependent and Independent Mechanisms.

Cardiovascular health requires the orchestration of the daily rhythm of blood pressure (BP), which responds to changes in light exposure and dietary patterns. Whether rhythmic light and feeding can modulate daily BP rhythm directly or via modulating intrinsic core clock gene is unknown. Using inducible global knockout mice (iBmal1KO), we explored the impact of rhythmic light, rhythmic feeding, or their combination on various physiological parameters.

Efficacy of wearable transcutaneous electrical acupoint stimulation bracelet on moderate-to-severe postoperative nausea and vomiting in patients after general anesthesia: a study protocol for a multicenter randomized controlled trial.

Background: Postoperative nausea and vomiting (PONV) is the most common complication following general anesthesia. Currently, pharmaceutical therapy is the primary method of treatment, but it has reached a plateau, and it is accompanied by inherent adverse reactions and high costs. Stimulation of the wrist acupuncture point PC6 is recommended as an effective means of preventing PONV.

Development and validation of a novel immune-related prognostic model and the potential metastatic mechanism in synovial sarcoma.

Background: Several clinical trials have shown that immunotherapy plays a pivotal role in the treatment of patients with metastatic synovial sarcoma. Immune-related genes (IRGs) have been demonstrated to predict the immunotherapy response in certain malignant tumours. However, the clinical significance of IRGs in patients with synovial sarcoma (SS) is still unclear.

Pyrazole-Mediated On-Surface Synthesis of Nickel/Nickel Oxide Hybrids for Efficient Urea-Assisted Hydrogen Production.

Creating densely functionalized supported materials without aggregation has been one of the ultimate goals for heterogeneous catalysts. Direct conversion of readily available bulk materials into highly dispersed supported materials could be highly beneficial for real applications. In this work, we invented an on-surface synthetic strategy for generating highly loaded and well-dispersed nickel nanoparticles on nickel oxide supports (Ni/NiO).

Research progress on the relationship between free fatty acid profile and type 2 diabetes complicated by coronary heart disease.

Patients with type 2 diabetes mellitus (T2DM) have a 2 to 3 times higher risk of cardiovascular disease compared to non-diabetic individuals, and cardiovascular disease has consistently been a leading cause of death among diabetic patients. Therefore, preventing cardiovascular disease in diabetic patients remains a significant challenge. In addition to classic indicators such as cholesterol and lipoproteins, previous studies have demonstrated that plasma level of free fatty acid (FFA) is closely related to the occurrence of atherosclerosis, particularly in T2DM patients.

A plateau freshwater shallow lake as a significant CO sink during the ice-covered period: A case study of Lake Wuliangsuhai, China.

Lakes are essential for estimating the global CO budget. However, approximately 50 % of lakes undergo periodic freezing, and there is limited research on the factors influencing the CO cycle and ice formation in freshwater lakes located in middle- and high-latitude plateaus during ice-covered periods. Using high-frequency meteorological-flux data collected over six consecutive months during the 2018-2019 freezing period of Lake Wuliangsuhai, this study explored the diurnal variation, daily accumulation, and monthly accumulation of the CO cycle and its influencing mechanisms at a half-hour scale.
