TMT-based proteomics reveals methylprotodioscin alleviates oxidative stress and inflammation via COX6C in myocardial infraction.

The effect of methylprotodioscin (MPD), a steroidal saponin obtained from medicinal plants, on myocardial infarction (MI) remains elusive. In this study, HL-1 and AC16 cells were subjected to injury induced by hypoxic environment, and a mouse model of MI was established by ligating the left anterior descending. MPD significantly increased viabilities and proliferations, improved the stability of MMP, reduced ROS and inflammatory factor levels in hypoxia cardiomyocytes.

[Risk factors for bronchopulmonary dysplasia in twin preterm infants: a multicenter study].

Objectives: To investigate the risk factors for bronchopulmonary dysplasia (BPD) in twin preterm infants with a gestational age of <34 weeks, and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.

Methods: A retrospective analysis was performed for the twin preterm infants with a gestational age of <34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020. According to their conditions, they were divided into group A (both twins had BPD), group B (only one twin had BPD), and group C (neither twin had BPD).

Enhanced Photoinduced Carrier Separation in Fe-MOF-525/CdS for Photocatalytic Hydrogen Evolution: Improved Catalytic Dynamics with Specific Active Sites.

Single-atom metal-anchored porphyrin-based metal-organic frameworks (MOFs) have shown excellent light absorption, catalytic sites, and high stability during photocatalytic reactions, while there are still challenges for facile assembly with quantum dots to enhance catalytic dynamics. Herein, a kind of Fe single atom-doped MOF material (Fe-MOF-525) was ball milled with CdS in a proper ratio through Fe-N and Fe-N-C bonding, which showed the enhanced photoinduced carrier separation ability. As a result, extended light absorption ranges of CdS/Fe-MOF-525 induced the promotion of the photocatalytic hydrogen (H) value (3638.

Prediction of the critical energy release rate for rat femoral cortical bone structure under different failure conditions.

Background And Objective: Critical energy release rate is a global fracture parameter that could be measured during the failing process, and its value may change under different failure conditions even in the same bone structure. The aim of this study was to propose an approach that combined the experimental test and finite element analysis to predict the critical energy release rates in the femoral cortical bone structures under compression and three-point bending loads.

Methods: Three-point bending and compression experiments and the corresponding fracture simulations were performed on the rat femoral cortical bone structures.

Case report: Recombinant human epidermal growth factor gel plus kangfuxin solution in the treatment of aplasia cutis congenita in a case with Adams-Oliver syndrome.

Sown alfalfa pasture decreases grazing intensity while increasing soil carbon: Experimental observations and DNDC model predictions.

Introduction: Grasslands are the most important land use in China and have experienced extensive degradation in the past few decades due to overgrazing. However, regionally viable solutions to grazing intensity alleviation remained elusive to date.

Methods: Here, we evaluated the grazing intensity effects of sown alfalfa pastures in northern China using an experiment-modeling combined approach that involved six sites in field experiments and five provinces in DNDC modeling of sown alfalfa pasture's forage production and carbon sequestration potentials in marginal lands.

A successful case of preimplantation genetic testing for monogenic disorder for aplasia cutis congenita.

Background: Aplasia cutis congenita (ACC), also called congenital cutaneous hypoplasia, is a serious disease in newborns. Children with ACC often die due to wound infections and bleeding. How the incidence of ACC can be reduced is a question that needs to be solved urgently.

[Application of extracorporeal membrane oxygenation in the treatment of persistent pulmonary hypertension of the newborn].

Objectives: To study the clinical value of extracorporeal membrane oxygenation (ECMO) in the treatment of persistent pulmonary hypertension of the newborn (PPHN).

Methods: A retrospective analysis was performed on the medical data of 11 neonates with PPHN who were treated with ECMO in the Neonatal Intensive Care Unit of Zhongshan People's Hospital from January 2015 to December 2021, involving the neonates' general information, clinical diagnosis, laboratory results, duration of ECMO treatment, complications during ECMO treatment, length of hospital stay, and outcome.

Results: Of the 11 neonates, 10 (91%) had successful weaning from ECMO, and 8 (73%) survived.

Network pharmacology and bioinformatics analysis identified essential genes of Jingulian in the treatment of rheumatoid arthritis and COVID-19.

Background: Patients with rheumatoid arthritis (RA) may be more susceptible to infection by coronavirus disease-19 (COVID-19) due to immune system dysfunction. However, there are still insufficient treatment strategies for patients with RA and COVID-19. Since Jingulian is a traditional Chinese medicine (TCM) with anti-viral and immune regulatory functions, our study aims to explore the detailed mechanisms of Jingulian in treating patients with RA and COVID-19.

miRNA-633 and KAI1 as Potential Biomarkers of Malignant Melanoma with Gastric Cancer.

Objective: Malignant melanoma with gastric cancer is one of the most malignant tumors. However, there have been no reports on the effects of KAI1 and miRNA-633 on the survival and prognosis of patients with malignant melanoma with gastric cancer.

Methods: Fifty patients with malignant melanoma and gastric cancer were collected from October 2017 to December 2019.

An air-stable, well-defined palladium-BIAN-NHC chloro dimer: a fast-activating, highly efficient catalyst for cross-coupling.

We report the synthesis, characterization and reactivity of an air-stable, well-defined acenaphthoimidazolylidene palladium-BIAN-NHC chloro dimer complex, [Pd(BIAN-IPr)(μ-Cl)Cl]. This rapidly activating catalyst merges the reactive properties of palladium chloro dimers, [Pd(NHC)(μ-Cl)Cl], with the attractive structural features of the BIAN framework. [Pd(BIAN-IPr)(μ-Cl)Cl] is the most reactive Pd(II)-NHC precatalyst discovered to date undergoing fast activation under both an inert atmosphere and aerobic conditions.

Quantitative probabilistic assessment of caffeine intake from tea in Chinese adult consumers based on nationwide caffeine content determination and tea consumption survey.

The as-constructed hybrid displays a superior reflection loss (RL) value of - 57.

Anodal transcranial direct current stimulation alleviates cognitive impairment in an APP/PS1 model of Alzheimer's disease in the preclinical stage.

Anodal transcranial direct current stimulation (AtDCS) has been shown to alleviate cognitive impairment in an APP/PS1 model of Alzheimer's disease in the preclinical stage. However, this enhancement was only observed immediately after AtDCS, and the long-term effect of AtDCS remains unknown. In this study, we treated 26-week-old mouse models of Alzheimer's disease in the preclinical stage with 10 AtDCS sessions or sham stimulation.
