Summary: This paper provides a systematic review of caffeine removal by the adsorption process, showing that adsorption is the preferred method for caffeine removal with capacities ranging between 10 and 1000 mg g(-1), and the pseudo-second order and Langmuir isotherm models are the best for fitting experimental data. Future research should focus on mechanistic understanding of adsorption, development of new adsorbents, and consideration of other kinetic models and thermodynamic studies.

Summary: Heteroatom-doped carbon nitride (C3N4) materials were investigated as supports for Au nanoparticles, which were anchored on sulfur-doped carbon nitride nanosheets (AuNPs@SCNN) and used as a catalyst for arsenic electroreduction. The synthesis of novel SCNN was achieved through a simple thermally induced copolymerization route using ammonium persulfate (APS) as a sulfur source. The integration of SCNN with AuNPs improved the assembly quality and interface, leading to enhanced catalytic activity. The composite (AuNPs@SCNN/GCE) modified glassy carbon electrode exhibited enhanced electrochemical responses for the electrocatalytic reduction of arsenic.

Summary: In this study, the detection of tryptophan enantiomers was achieved using immunochromatographic assays and electrochemical methods. The sensor response showed a good linear relationship with tryptophan concentration in the range of 0.08-20.0 μM, with a detection limit of 0.03 μM. The sensor is stable and not susceptible to interfering species, making it a reliable tool for determining tryptophan levels in biological samples and diagnosing specific diseases.

Summary: We reported a novel electrochemical sensor for the indirect determination of cyanuric acid (CA) using the complex formation between CA and melamine (MEL) for the first time. The sensor utilized the electrochemical conversion of MEL to electroactive polymelamine, with the decline in current intensity upon the addition of CA serving as the sensor response. A calibration curve was constructed using square wave voltammetry, with a limit of detection of 80.28 mu mol L-1. The proposed method showed excellent recovery range (91.2-101.0%) for real sample analysis.

Summary: We report on the synthesis and characterization of a dual stimuli-responsive hydrogel for pH and temperature-sensitive delivery of curcumin (CUR) anticancer drug. The release of CUR from the hydrogel was higher at acidic pH values, and the hydrogel remained stable at 37 degrees C. To enable thermal responsivity, polydopamine nanoparticles were embedded in the hydrogel. The GGPDNCs hydrogel is engineered to respond to both pH and temperature stimuli.

Summary: In this research, the complexation of a newly synthesized covalent organic framework (schiff base network1) with different cations, including Hg2+, was studied. The results showed that schiff base network1 had a stronger interaction with Hg2+ compared to other cations, making it a potential ionophore for the development of a Hg2+ potentiometric sensor. A Hg2+ selective PVC membrane coated graphite electrode was successfully created using schiff base network1, which exhibited excellent response and sensitivity for the detection of Hg2+ in a wide range of concentrations. The electrode also demonstrated good performance in non-aqueous environments and had a long lifespan.

Summary: Rhabdomyosarcoma is a rare cancer that affects skeletal muscle, primarily in children and young adults. The treatment strategies for this disease include multi-agent chemotherapies following surgical resection and radiotherapy. This review provides a detailed clinical understanding of rhabdomyosarcoma, including its classification, diagnosis, and treatment strategies. The impact of apoptosis, macro-autophagy, and the unfolded protein response on chemotherapy response is discussed. Additionally, the use of in vivo mouse and zebrafish models and in vitro three-dimensional bioengineering models for screening future therapeutic approaches and promoting muscle regeneration is explored.
