This study introduces two novel sandwich-type tungsten-oxygen cluster compounds synthesized by hydrothermal methods, H(CHNH){Na(HO)[Mn(HO)(GeWO)]} (Compound 1) and H(CHNH){Na(HO)[Co(HO)(GeWO)]}·17HO (Compound 2). The two compounds comprise cluster anions [GeWO] coordinated with transition metal atoms, either Mn or Co, and are stabilized by organic ligands. These compounds are crystallized in the hexagonal crystal system and P6/m space group.

Methods: A total of 94 stable chronic obstructive pulmonary disease (COPD) patients were recruited for the study.Plasma HS levels were measured using fluorescence probe. Fluorescence quantitative polymerase chain reaction was used to measure HS synthase cystathionine-γ-lyase (CSE) mRNA and cystathionine-β-synthesis enzyme (CBS) mRNA.
