Hydrophilic acrylic intraocular lens opacification after descemet stripping automated endothelial keratoplasty

In an eye with multiple prior intraocular surgery and iatrogenic aniridia, the hydrophilic acylic intraocular lens opacification occurred after Descemet Stripping Automated Keratoplasty, which was reported as a result of multiple intraocular surgeries and iatrogenic aniridia. Case Report: For her cataract, a 34-year-old woman with a history of penetrating keratoplasty for advanced keratoconus and subsequent Urts-Zavalia Syndrome underwent phacoemulsification and hydrophilic acrylic IOL implantation. Multiple glaucoma surgeries, including two glaucoma drainage implants, were performed in order to treat post-PKP glaucoma. IOL opacification may result from direct contact between the IOL surface and exogenous air in an eye with UZS and iatrogenic aniridia.

The effect of Piper betle against Candida albicans adherence to denture acrylic surfaces

P. betle leaf extract was used in this study to determine Candida albicans adhesion on denture acrylics, according to the study's aim. Using the agar well bioassay, anticandidal activity of a variety of concentrations of the leaf extract was tested against C. albicans and seven laboratory isolates. Both, the leaf extract of 4,000 ppm and the commercial denture cleanser demonstrated significant reduction of C. albicans adhesion on denture acrylics, according to the study. There was no significant difference between adhesion in an 8000 ppm concentration extract and the commercial denture cleanser of equal magnitude, meaning that betel leaf extract is as effective as the commercial denture cleanser in preventing the adhesion of C. albicans on denture acrylic surfaces.

The Comparison between Black Cumin Extract and Betel Leaf Extract As Antifungal Potential to Candida Albicans on Acrylic Resin Denture Base

Candida albicans can stick to a plaque on the denture base and engender denture stomatitis, as shown by a plaque. This research aims to determine the comparison of antifungal properties of black cumin and betel leaf extract to Candida albicans on the acrylic resin denture base. Treatment group 1 used aquadest as a control negative, while treatment group 2 used a black cumin extract with a % of 0. 2 percent, while treatment group 2 used betel leaf extract with a concentration of 50%. There was no significant difference between a total colony of Candida albicans in the treatment group with a concentration of 0. 2 percent black cumin and a 50% betel leaf content in the treatment group. The black cumin extract was no more effective in stopping Candida albicans from growing on the acrylic resin denture base than betel leaf extract, according to the study.

The Comparison of Color Stability of Aloe Vera Gel and Chlorhexidine Solution on Acrylic Teeth

Compared to other denture cleaners, particularly chlorhexidine, there is insufficient information regarding aloe vera color change property on acrylic teeth. The present study was designed to compare the aloe vera and chlorhexidine solutions' color change behavior on denture acrylic teeth. The sample size in each group was 21 acrylic teeth that were randomly divided into aloe vera gel 100% and chlorhexidine solution 2% groups. The tooth's brightness in the chlorhexidine group was lower than that in the aloe vera group. After 36 hours of immersion similar to the chlorhexidine solution, clinicianians should be aware that aloe vera gel does not change denture acrylic teeth's color. Aloe vera gel is a good cleaner for denture acrylic teeth that can't use chlorhexidine, and it's safe to clean denture acrylic teeth without worrying about the denture's color change.

Partial nasal bone reconstruction with acrylic bone cement: experimental study

Abstract Background The aim of this research was to determine the use of acrylic bone cement in partial nasal bone reconstruction. The partial bone segments on the bilateral nasal bones of the bilateral nasal bones were marked and removed symmetrically. In an experimental study, a synthetic graft powder made of acrylic bone cement was applied, and a partial bone segment removed from the right side of the experiment was embedded in the control group as an autograft. Allergens Surrounding Soft tissue on synthetic and autograft were the same as in terms of chronic inflammation. Conclusions This research found no significant differences between the use of acrylic bone and the use of an autograft for partial nasal bone reconstruction in terms of graft or tissue regeneration in terms of graft or tissue regeneration. Acrylic bone cement may also be a good alternative to nasal bone restoration.

In Vitro Assessment of Poly-N-Vinylpyrrolidone/Acrylic Acid Nanoparticles Biocompatibility in a Microvascular Endothelium Model

Both the CFSE dye and the DiI dye were localized to the treated cells' cytoplasm on uptake. At higher concentrations of 0. 033 and 0. 066 mg/mL, treatment with p did not affect normal and was tested with LPS, HMEC-1 cells at 0. 010 mg/mL, causing a dose-dependent decrease of these cells'u2019 viability at the higher levels of 0. 033 and 0. 066 mg/mL. In addition, we investigated the expression of adhesion molecules. The use of individual adhesion molecules in the nexus of individual adhesion molecules does not influence individual adhesion molecules'u2019 expression.

Effects of Preparation and Self-Assembly of Poly(Styrene-Acrylic Acid) (P(St-AA)) Microspheres upon Constructed Photonic Crystals with Structural Color on Wood Surfaces

Colloidal microspheres could be used as raw materials to build the photonic crystal modification layers on wood surfaces, and the wood will have a stunning structural color effect. The effect of the amount of emulsion coating per unit surface area and ambient temperature on the photonic crystals' optical properties were investigated. The particle size of the synthesized microspheres increased with increase of initiator quantity and reaction temperature, as well as the reduction of emulsifier; however, the effect of reaction time on microspheres was less predictable.

Nano-SiO 2 -Modified Waterborne Acrylic Acid Resin Coating for Wood Wallboard

The study of environmental protection coating technologies for wood wallboard is of utmost importance as one of the main products of the whole wood custom home. Herein, we designed a simple yet effective way to produce WAA resin coatings with excellent results using SiO 2 nanoparticles as modifiers, as well as investigating the feasibility of wood wallboard. When the modifier nano-SiO 2 was added at 1 wt% in the WAA resin coating, the wood wallboard finishes showed good results, according to the combined performance data. This present work reveals that the nano-SiO 2 -modified WAA resin coating for wood wallboard has a wide application range.
