Ln Induced Thermally Activated Delayed Fluorescence of Chiral Heterometallic Clusters LnAg.

A series of TADF-active compounds: 0D chiral Ln-Ag(I) clusters L-/D-LnAg-0D (Ln=Eu/Gd) and 2D chiral Ln-Ag(I) cluster-based frameworks L-/D-LnAg-2D (Ln=Gd) has been synthesized. Atomic-level structural analysis showed that the chiral Ag(I) cluster units {AgS} in L-/D-LnAg-0D and L-/D-LnAg-2D exhibited similar configurations, linked by varying numbers of [Ln(HO)] (x=6 for 0D, x=3 for 2D) to form the final target compounds. Temperature-dependent emission spectra and decay lifetimes measurement demonstrated the presence of TADF in L-LnAg-0D (Ln=Eu/Gd) and L-GdAg-2D.

Efficacy and safety of the Latarjet procedure for the treatment of athletes with glenoid bone defects ≥ 20%: a single-arm meta-analysis.

Background: The shoulder joint is the most commonly dislocated joint in the human body, and the recurrence rate exceeds 50% after nonsurgical treatment. Although surgical treatment reduces the recurrence rate, there is controversy regarding the optimal surgical approach. Previous studies suggest that the Latarjet procedure yields favourable outcomes for specific populations at risk of recurrence, such as competitive athletes with significant glenoid defects.

Chiral lanthanide-silver(I) cluster-based metal-organic frameworks exhibiting solvent stability, and tunable photoluminescence.

Due to the lack of effective synthetic strategies, the preparation of chemically stable chiral Ag(I) cluster-based materials for assembly remains challenging. Here, we have developed an approach to synthesize three pairs of chiral Ln-Ag(I) cluster-based metal-organic frameworks (MOFs) named l-LnAg5-3D (Ln = Gd for 1-L, Eu for 2-L, and Tb for 3-L) and d-LnAg5-3D (Ln = Gd for 1-D, Eu for 2-D, and Tb for 3-D) by employing a chiral Ag(I) cluster ({AgS}) as the node and Ln ion as the inorganic linker. Structural analysis revealed that the chiral ligands induced chirality through the entire structure, resulting in a chiral helix arrangement of the -symmetric chiral {AgS} nodes and Ln ions.

Preorganized Nitrogen Sites for Au Amidation: A Generalizable Strategy toward Precision Functionalization of Metal Nanoclusters.

Atomically precise metal nanoclusters have received tremendous attention due to their unique structures and properties. Although synthetic approaches to this kind of nanomaterial have been well developed, methods toward precision functionalization of the as-synthesized metal nanoclusters are extremely limited, hindering their interfacial modification and related performance improvement. Herein, an amidation strategy has been developed for the precision functionalization of the Au nanocluster based on preorganized nitrogen sites.

Advanced age is associated with increased adverse outcomes in patients undergoing middle cerebral artery stenting.

Purpose: This study tried to evaluate whether advanced age has an increased incidence of major complications in patients undergoing MCA stenting.

Methods: A total of 348 patients who underwent MCA stenting were reviewed from a prospectively maintained database. Ninety-day ischemic stroke, intracerebral hemorrhage, and death outcomes were compared among the young (≤40 years old), middle (41-60 years old) and old (≥61 years old) groups.

[Screening and identification of steroidal saponins-producing endophytes from Paris polyphylla var. chinensis Franch].

Two endophytic strains SS01 and SS02 with the potential for producing steroidal saponins were isolated from the underground stems of Paris polyphylla var. chinensis Franch. The TLC comparison indicated that there are 3 sports with similar R(f) between the metabolites of SS01 and the saponins of Paris polyphylla var.
