Pd Nanoparticles Immobilized on Pyridinic N-Rich Carbon Nanosheets for Promoting Suzuki Cross-Coupling Reactions.

Palladium (Pd) catalysts play a crucial role in facilitating Suzuki cross-coupling reactions for the synthesis of valuable organic compounds. However, conventional heterogeneous Pd catalysts often encounter challenges such as leaching and deactivation during reactions, leading to reduced catalytic efficiency. In this study, we employed an innovative intercalation templating strategy to prepare two-dimensional carbon nanosheets with high nitrogen doping derived from petroleum asphalt, which were utilized as a versatile support for immobilizing Pd nanoparticles (Pd/N-CNS) in efficient Suzuki cross-coupling reactions.

The efficacy of bandage contact lens in relieving the aggravation of dry eye disease after complicated cataract or/and IOL surgery.

Purpose: In the present study, we aimed to evaluate the efficacy of the bandage contact lens (BCLs) in the treatment of dry eye disease (DED) after complicated cataract or/and intraocular lens (IOL) surgery.

Methods: In this retrospective, single-centered, observational study, we collected data from 69 patients who underwent complicated cataract or/and IOL surgery. Of these, 35 cases wore their own BCLs immediately after the operation, while the other 34 cases did not have their own BCLs and were instead covered with gauze.

Effect of two different preoperative calculation schemes on visual outcomes of patients after toric intraocular lens implantation.

Purpose: To compare the postoperative visual outcomes of two different preoperative corneal incision schemes in TECNIS toric intraocular lens (IOL) implantation.

Methods: In this randomized controlled study, patients with preoperative corneal astigmatism greater than 1.0 diopter (D) were included.

Case series: "Double arch" changes caused by capsule contraction syndrome after cataract surgery in highly myopic eyes.

Background: Capsule contraction syndrome (CCS) after cataract surgery causes intraocular lens (IOL) haptic flexion and IOL optic displacement in most former reports. However, there are few reports on CCS-induced deformation of the IOL optic. We report two cases of CCS after cataract surgery in highly myopic eyes and describe a previously unreported "double arch" complication.

Application of capsular bag relaxation for capsular contraction syndrome.

The present study analyzed the surgical method and clinical effects of capsular bag relaxation surgery (CBRS) for the treatment of capsular contraction syndrome (CCS), which usually occurs post-phacoemulsification. The retrospective case study comprised of a total of 25 patients (25 eyes) who developed CCS after phacoemulsification and subsequently underwent CBRS. Among these patients, 15 patients (15 eyes) received actinoid relaxing incisions and 10 patients (10 eyes) underwent a second continuous curvilinear capsulorhexis.

[Analysis of TGFBI gene mutation in a Chinese pedigree affected with lattice corneal dystrophy].

Objective: To explore the clinical features and mutation of TGFBI gene in a Chinese pedigree affected with lattice corneal dystrophy (LCD).

Methods: Genomic DNA was extracted from 35 members including 11 patients from the pedigree. The 17 exons and splicing region of introns of the TGFBI gene were amplified by PCR.

[Analysis of TGFBI gene mutation in a Chinese family affected with Reis-Bucklers corneal dystrophy].

Objective: To analyze the clinical features and TGFBI gene mutation in a Chinese family affected with Reis-Bucklers corneal dystrophy.

Methods: Genomic DNA was extracted from 53 members including 9 patients from the family. The 17 exons and splice region of introns of the TGFBI gene were amplified by PCR and directly sequenced.

Adsorption of 5-sodiosulfoisophthalic acids from aqueous solution onto poly(2-vinylpyridine) resin.

In the present study, the performance, behavior and mechanism of synthetic poly(2-vinylpyridine) resin (WH-225) adsorbing 5-sodiosulfoisophthalic acids (SIPA) from the aqueous solution were investigated, and two commercial adsorbents, namely, hypercrosslinked adsorbent NDA-100 and macroporous adsorbent XAD-4 were employed as reference. Compared to NDA-100 and XAD-4, WH-225 has the highest capacity for adsorbing SIPA from the aqueous solution, which is verified by the related adsorption experiments. The investigation indicated that electrostatic interaction is an important factor in affecting the adsorption behavior of WH-225.
