Tranexamic acid dosage for spinal surgery: a meta-analysis.

Purpose: We conducted this meta-analysis of randomized controlled trials (RCTs) to compare the efficacy of different doses of intravenous tranexamic acid (TXA) in spinal surgery.

Methods: We searched relevant academic articles from PubMed, Embase, the Cochrane Library, and CNKI. Two reviewers independently selected studies, assessed quality, extracted data, and evaluated the risk of bias.

Inducing laccase activity in white rot fungi using copper ions and improving the efficiency of azo dye treatment with electricity generation using microbial fuel cells.

This work presents a white rot fungus-microbial fuel cell (WRF-MFC) that uses WRF that is grown at its cathode. Adding Cu to the fungi-containing solid medium stimulated WRF-secreting laccase, which catalyzed the redox reaction in the MFC and thereby promoting the generation of electricity. Adding 12.

IL-16 regulates macrophage polarization as a target gene of mir-145-3p.

Background: Interleukin 16 is an immunomodulatory chemokine that signals through CD4 + T cells, monocytes, macrophages and dendritic cells. Its expression in immune-related cells enhances the antimicrobial effect and inhibits HIV replication in macrophages. However, the role of IL-16 in macrophage polarization is uncertain.

An inorganic-organic hybrid photochromic material with fast response to hard and soft X-rays at room temperature.

A photochromic compound with fast response to Mo-Kα (4 min) and Al-Kα (1 s) X-rays was synthesized using a cluster of high-Z atoms and a flexible viologen zwitterion. The coloration time of 1 s when exposed to soft X-rays is the recorded minimum for X-ray-induced photochromic materials, indicating a potential to detect low-energy X-rays.

Design Strategy for Improving Optical and Electrical Properties and Stability of Lead-Halide Semiconductors.

Broad absorption, long-lived photogenerated carriers, high conductance, and high stability are all required for a light absorber toward its real application on solar cells. Inorganic-organic hybrid lead-halide materials have shown tremendous potential for applications in solar cells. This work offers a new design strategy to improve the absorption range, conductance, photoconductance, and stability of these materials.

Innovative encapsulated oxygen-releasing beads for bioremediation of BTEX at high concentration in groundwater.

Both a low concentration of dissolved oxygen and the toxicity of a high concentration of BTEX inhibit the bioremediation of BTEX in groundwater. A novel method of preparing encapsulated oxygen-releasing beads (encap-ORBs) for the biodegradation of BTEX in groundwater was developed. Experimental results show that the integrality and oxygen-releasing capacity of encap-ORBs exceeded those of ORBs.

Reversible Single-Crystal-to-Single-Crystal Transformation and Magnetic Change of Nonporous Copper(II) Complexes by the Chemisorption/Desorption of HCl and HO.

Vapor-responsive magnetic materials are highly promising for applications as chemical switches or sensors. Compared with porous materials, nonporous species benefit in overcoming the intrinsic conflict between magnetic exchange and porosity but usually suffer from the powdering of single crystals, which hinders the understanding of the structural nature of vapor response and magnetic switch. Single-crystal-to-single-crystal (SCSC) transformation of nonporous compounds through the desorption/absorption of gaseous HCl is unprecedented.
