AI Article Synopsis
- Silicon oil is used to treat retinal detachment but can cause complications like narrowing of the angle and increased intraocular pressure due to synechial closures.
- The purpose of the video is to demonstrate how to manage early synechial closures caused by silicon oil tamponade.
- Surgical pupilloplasty effectively breaks synechias and prevents further vision deterioration by opening up blocked anterior chamber angles.
Article Abstract
Background: Silicon oil is an important adjunct for achieving internal tamponade in the treatment of retinal detachment. Silicone oil tamponade often leads to narrowing of the angle and development of adhesions between the iris and anterior chamber angle structures, with consequential elevation of the intraocular pressure. The video showcases the management of these challenging scenarios.
Purpose: To highlight the management of early synechial closures due to silicon oil tamponade.
Synopsis: The video highlights the management of early synechial closure following silicon oil tamponade. Surgical pupilloplasty has been demonstrated to break the peripheral anterior synechias on intraoperative gonioscopy as well as on anterior segment optical coherence tomography (AS-OCT). Performing pupilloplasty in the early phase of development of peripheral anterior synechias (PAS) helps to break the existing synechias and prevent angle closure and sequential deterioration of vision.
Highlights: Surgical pupilloplasty helps to relieve the post silicon oil-induced secondary angle closure glaucoma by breaking the peripheral anterior synechias and significantly opening the anterior chamber angles.

A novel Pickering interfacial biocatalysis (PIB) system has been, for the first time, successfully applied for the enzymatic selective hydrolysis of algae oils and fish oils to enrich n-3 PUFAs glycerides. Lipase AY 400SD was identified and adsorbed on hydrophobic hollow core-shell silica nanoparticles, resulting in the formation of the immobilized enzyme AY 400SD@HMSS-C. The biocatalyst was employed as an emulsifier to stabilize the water-in-oil Pickering emulsion, resulting in the successful construction of the PIB system.

Because a significant portion of oil remains in carbonate reservoirs, efficient techniques are essential to increase oil recovery from carbonate reservoirs. Wettability alteration is crucial for enhanced oil recovery (EOR) from oil-wet reservoirs. This study investigates the impact of different substances on the wettability of dolomite and calcite rocks.

In chemical-enhanced oil recovery (cEOR), surfactants are widely used but face significant stability challenges in high-salinity brine, where they often degrade or precipitate. Existing methods, such as adding cosurfactants, offer limited compatibility with anionic surfactants and raise economic concerns, creating a need for more robust solutions. This study introduces a novel approach to enhance the stability of anionic surfactants in extreme salinity conditions by incorporating silicon dioxide (SiO) nanoparticles (NPs).

The dosages of colloidal silicon seeds in the seed-induced synthesis of TS-1 zeolites were investigated in detail. The characterization results revealed that the colloidal silicon seeds not only reduced the particle sizes but also promoted the incorporation of titanium atoms into the framework of TS-1 zeolites as prepared. SEM images and particle size distribution (PSD) confirmed that the particle sizes of TS-1 zeolite could be effectively reduced to about 150 nm.

Article Synopsis
- This study investigates the use of shungite ore and its concentrate from Kazakhstan as fillers in nitrile butadiene rubber composites.
- The flotation process significantly increased the carbon content in shungite while reducing silicon oxide, impacting the physical and mechanical properties of the rubber.
- Results showed that replacing carbon black with shungite improved certain properties of the rubber, such as reduced viscosity and increased tensile strength, without significantly affecting oil resistance.
