Evaluation of the Long-Term Corneal Biomechanics Following SMILE With Different Residual Stromal Bed Thickness in Rabbits.

Purpose: The long-term safety of small-incision lenticule extraction (SMILE) surgery for correcting high myopia with a residual stromal bed thickness (RST) less than 50% of the central corneal thickness (CCT) was investigated from a biomechanical perspective.

Methods: Twelve rabbits were enrolled in this study, in which the right eye underwent SMILE surgery (the corneal cap thickness was one third of the preoperative CCT, approximately 120 µm), and the left eye served as the control. The rabbits were evenly divided into two groups, with the RST of 50% and 30% of the preoperative CCT in each group, respectively.

[Controllability and predictability of riboflavin-ultraviolet A collagen cross-linking: advances in experimental techniques and theoretical research].

Riboflavin-ultraviolet A (UVA) collagen cross-linking has not only achieved good clinical efficacy in the treatment of corneal diseases such as dilatation keratopathy, bullae keratopathy, infectious keratopathy, and in the combined treatment of corneal refractive surgeries, but also its efficacy and safety in scleral collagen cross-linking have been initially confirmed. To better promote the application of cross-linking in the clinical treatment of corneal and scleral diseases, exploring controllability and predictability of the surgical efficacy are both important for evaluating the surgical efficacy and personalized precision treatment. In this paper, the progress on the cross-linking depth of riboflavin-UVA collagen cross-linking, and its relationship with the cross-linking effect will be reviewed.

DNL-17: A Small-Pore Aluminophosphate in ABC-6 Family with 24 Stacking Layers Unraveled by Three-Dimensional Electron Diffraction.

Small-pore aluminophosphate (AlPO) molecular sieves (MSs), particularly those in the ABC-6 family, have gained significant attention for their unique capabilities in selective adsorption and energy storage.

Abcb1 is involved in the efflux of trivalent inorganic arsenic from brain microvascular endothelial cells.

Arsenic (As) can penetrate brain tissue through the blood-brain barrier (BBB), and the ATP-binding cassette subfamily B member 1 (Abcb1) has been shown to facilitate the transport of inorganic arsenic (iAs) in animal liver, small intestine, and yeast. However, the relationship between Abcb1 and BBB has not been reported, and the mechanism of brain microvascular endothelial cells Abcb1 on the transport of iAs needs to be further studied. Increased arsenic levels were observed in mice exposed to 25 mg/L or 50 mg/L of sodium arsenite (NaAsO) in drinking water, and both arsenic uptake and efflux were detected in bEnd.

Rapid determination of Se(IV) and tSe in fungal samples by foam electrode-based electrolytic hydride generation coupled atomic fluorescence spectrometry.

The key to accurately identifying trace heavy metal elements is to achieve efficient sample introduction while shielding the interference of matrix components. Taking the electrolytic hydride generation (EHG) technology as an example, this paper explored the effects of cathode materials and structural factors on the electrosynthesis of hydrogen selenide (HSe), particularly on suppressing interference from coexisting components. Systematic electrochemical and spectroscopic tests show that the nickel-based electrode can promote the generation of HSe, while the multi-layer foam structure with large specific surface area, rich pores and weak gas evolution effect improves the yield and stability of electrosynthesis reaction.
