Within the base excision repair (BER) pathway, essential for DNA repair, apurinic/apyrimidinic endonuclease 1 (APE1) is a critical player. Increased APE1 expression correlates with the phenomenon of multidrug resistance in diverse cancers, encompassing lung cancer, colorectal cancer, and other malignant tumors. Accordingly, a decrease in APE1 activity is favorable for optimizing cancer treatment outcomes. Protein targeting and function limitation are facilitated by the utilization of inhibitory aptamers, specialized oligonucleotides. In this investigation, we engineered an inhibitory aptamer for APE1 utilizing the SELEX method, a technique for the systematic development of ligands through exponential enrichment. Immunity booster Carboxyl magnetic beads acted as the carrier, while APE1, tagged with a His-Tag, served as the positive selection marker; conversely, the His-Tag itself became the negative selection marker. The aptamer APT-D1 was selected owing to its high binding affinity to APE1, indicated by a dissociation constant (Kd) of 1.30601418 nanomolar. Electrophoresis results indicated that 16 molar APT-D1 was sufficient to completely inhibit APE1, at a concentration of 21 nanomoles. Our findings indicate that these aptamers are applicable for early cancer detection and therapy, and as a crucial instrument for investigating the function of APE1.

Due to its ease of use and safety, instrument-free chlorine dioxide (ClO2) is being extensively adopted as a preservative in the fruit and vegetable industry. This study detailed the synthesis, characterization, and subsequent application of a series of carboxymethyl chitosan (CMC) molecules, each bearing citric acid (CA) substituents, to create a novel slow-release ClO2 preservative for longan. The successful preparation of CMC-CA#1-3 samples was validated by the UV-Vis and FT-IR spectral data. Further potentiometric titration quantified the mass ratios of CA grafted onto the respective CMC-CA#1-3 samples, yielding 0.181, 0.421, and 0.421. The slow-releasing ClO2 preservative's formulation was meticulously optimized for composition and concentration, culminating in the following superior formula: NaClO2CMC-CA#2Na2SO4starch = 3211. The preservative's ClO2 release, at a temperature between 5 and 25 degrees Celsius, took a maximum of more than 240 hours to complete, with the highest release rate always observed within the 12-36 hour window. Longan treated with 0.15-1.2 grams of ClO2 preservative demonstrated a statistically significant (p < 0.05) enhancement in L* and a* values, yet exhibited a decrease in respiration rate and total microbial colony counts, relative to the control group (0 grams ClO2 preservative). Eighteen days after storage, the longan samples treated with 0.3 grams of ClO2 preservative revealed the most prominent L* value of 4747, combined with the lowest respiration rate (3442 mg/kg/h), showcasing the ideal pericarp colour and pulp quality. In this study, a safe, effective, and straightforward solution for longan preservation was established.

Dynamic light scattering analysis of the Fe3O4 nanoparticles demonstrated a consistent particle size, showing a mean hydrodynamic diameter of 1354 nm with a polydispersity index of 0.530. The Fe3O4@AHSG adsorbent, under similar analysis, exhibited a similar consistent size of 1636 nm, with a polydispersity index of 0.498. Vibrating sample magnetometer (VSM) results indicated superparamagnetic behavior in both Fe3O4 and Fe3O4@AHSG samples, with Fe3O4 demonstrating a greater saturation magnetization (Ms). Through dye adsorption studies, it was determined that the ability to adsorb dye increased as the initial methylene blue concentration and the adsorbent dosage were amplified. A substantial correlation existed between the dye solution's pH and its adsorption, with the highest adsorption rate observed at basic pH levels. Sodium chloride's presence diminished the adsorption capacity, a consequence of the heightened ionic strength. Thermodynamic analysis corroborated the adsorption process's spontaneous and thermodynamically favorable nature. Kinetic investigations demonstrated that the pseudo-second-order model exhibited the optimal agreement with the empirical data, implying that chemisorption was the rate-determining stage. Fe3O4@AHSG nanoconjugates demonstrated a remarkable adsorption capacity, making them a promising candidate for the efficient removal of MB dye from wastewater streams.
