Construction of 1D Molecular Conductive Wires Through a Polarized Gene Weaving Strategy for Efficient Electromagnetic Wave Absorption.

The growing threat of electromagnetic pollution has become a pressing safety concern. Metal-organic framework (MOF) derivatives are considered ideal candidates for mitigating electromagnetic radiation. However, due to the limitations imposed by complex post-processing and disruption of pristine crystal structures, the mechanisms of electromagnetic wave absorption remain unclear, let alone achieving atomic-level regulation in MOF derivatives.

Enhancing Two-Photon Excited Fluorescence of Metal-Organic Framework Single Crystals through Modulation of Inorganic Nodes.

Regulation of the two-photon excited fluorescence (TPEF) emission intensity and wavelength of metal-organic framework (MOF) crystals with similar constitutions presents a significant challenge. In this study, two MOFs, Zn-BTPPA and Cd-BTPPA, were constructed using tetrakis(1,1'-biphenyl-4-carboxylic acid)-1,4-benzenediamine (HBTPPA) as the organic ligand and mononuclear Zn and trinuclear Cd inorganic nodes, respectively. The incorporation of HBTPPA within the MOF structures enables effective TPEF emission in both Zn-BTPPA and Cd-BTPPA.

Construction of a redox-active metal-organic framework with an octanuclear lithium one-dimensional building block.

A stable lithium metal-organic framework, constructed using a redox-active ,,','-tetrakis(4-carboxyphenyl)-1,4-phenylenediamine linker and Li cluster-based one-dimensional rod secondary building unit, exhibits good stability and reversible redox activity. The Li-MOF, which can be oxidized by AgNO, has the potential to function as an electrochromic device, thereby advancing the development of smart MOF materials.

Bimetal-Organic Frameworks Incorporating Both Hard and Soft Base Active Sites for Heavy Metal Ion Capture.

The design and synthesis of stable porous materials capable of removing both hard and soft metal ions pose a significant challenge. In this study, a novel metal-organic framework (MOF) adsorbent named CdK--COTTTB was developed. This MOF material was constructed using sulfur-rich -cyclooctatetrathiophene-tetrabenzoate (-HCOTTTB) as the organic ligand and oxygen-rich bimetallic clusters as the inorganic nodes.

Square-planar Tetranuclear Cluster-based Alkaline Earth Metal-organic Frameworks with Enhanced Proton Conductivity.

Alkaline earth (AE) metal complexes have garnered significant interest in various functional fields due to their nontoxicity, low density, and low cost. However, there is a lack of systematic investigation into the structural characteristics and physical properties of AE-metal-organic frameworks (MOFs). In this research, we synthesized isostructural MOFs consisting of AE(μ-Cl) clusters bridged by benzo-(1,2;3,4;5,6)-tris(thiophene-2'-carboxylic acid) (BTTC) ligands.

Retroperitoneal Laparoscopic Debridement and Drainage for Pancreatic Abscess.

In patients with severe necrotizing pancreatitis, pancreatic necrosis and secondary infection of surrounding tissues can quickly spread to the whole retroperitoneal space. Treatment of pancreatic abscess complicating necrotizing pancreatitis is difficult and has a high mortality rate. The well-accepted treatment strategy is early debridement of necrotic tissues, drainage, and postoperative continuous retroperitoneal lavage.

[Changes of serum BAFF and IL-21 levels in patients with systemic lupus erythematosus and their clinical significance].

Aim: To investigate the changes of serum BAFF and IL-21 levels in the patients with systemic lupus erythematosus (SLE) and explore their clinical significance.

Methods: The serum levels of BAFF and IL-21 were detected by enzyme-linked immunosorbent assay (ELISA).

Results: The levels of serum BAFF and IL-21 in the patients with SLE were obviously higher than those in healthy control group.

[Serum IL-21 level in patients with primary Sjogren's syndrome and clinical significance of IL-21].

Aim: To investigate the relation between the change of serum IL-21 level and other laboratory indexes by detecting serum IL-21 level from patients with primary Sjogren's syndrome (pSS) and explore the role of IL-21 in pSS.

Methods: The level of serum IL-21 from 40 pSS patients diagnosed according to 2002 revised international classification criteria for pSS and 30 healthy persons were detected by enzyme-linked immunosorbent assay(ELISA) respectively. Meanwhile, FT3, FT4, TSH, TgAb, TPOAb were detected by Immunochemiluminescent technique.
