Analysis of Changes of Ang-2 and TNF-α Levels in Patients with AMI Complicated with Pulmonary Infection and Drug Resistance of Infectious Pathogens.

Objective: This study aimed to investigate the changes in angiopoietin-2 and tumor necrosis factor α levels in patients with acute myocardial infarction complicated with pulmonary infection.

Methods: Retrospective selection was conducted on 61 patients with acute myocardial infarction complicated with pulmonary infection and 122 patients with simple acute myocardial infarction. A comparison was made between the two groups regarding general information and serum myocs.

Exosomes from Adipose-Derived Mesenchymal Stem Cells Protect Against Cyclophosphamide-Induced Cardiotoxicity in Rats.

A certain dosage of cyclophosphamide (CYP) in clinical applications contributes to severe cardiotoxicity. Herein, this study explored the impact of adipose-derived mesenchymal stem cell (AdMSC)-exosomes (Exos) on CYP-induced cardiotoxicity.AdMSCs and AdMSCs-Exos were isolated and identified.

Morphological transition of gold nanostructures induced by continuous ultraviolet irradiation.

Gold nanoparticles were synthesized through a continuous UV irradiation method using citric acid as a reducer and protective agent. After a period of continuous UV irradiation, the nanoparticles transformed into two-dimensional (2D) nanonetworks, porous nanoplates and compact nanoplates with hexagonal, triangular or truncated triangular pores through a self-assembly process which was dependent on the citric acid concentration. Selected area electron diffraction (SAED) patterns indicated that both the nanonetworks and the porous nanoplates were single crystalline.
