Efficiency Encapsulation of FK506 with New Dual Self‐Assembly Multi‐Hydrophobic‐Core Nanoparticles for Preventing Keratoplasty Rejection (Adv. Healthcare Mater. 21/2023)

Effects of the immunosuppressant FK506 on a penetrating keratoplasty rejection model in the rat.

PURPOSE The immunosuppressive effects of FK506 on allogeneic corneal transplantation were tested in a rat model. METHODS Inbred-strain Lewis rats were used as recipients, and Fisher rats were used as donors. Intraperitoneal injection of FK506 (0.3, 1.0, and 3.0 mg/kg per day) was administered for 2 weeks, and the grafts were inspected by clinical evaluation. Mixed lymphocyte culture assay, us...

Metamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).

By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.

Hybrid Nanoparticles: Corrosion‐Protected Hybrid Nanoparticles (Adv. Sci. 12/2017)

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Risk Factors for Failure of Keratoplasty in Keratoconus: Penetrating vs. Deep Anterior Lamellar Keratoplasty

Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...
