Facial Rejuvenation with Fast Recovery Suspension Technique.

Minimally invasive facial rejuvenation techniques are gaining attention because of their advantages such as less trauma, quick recovery, high safety, obvious results, and repeatable operation. In this article, the principle, the operation method, advantages, and disadvantages of the new fast recovery suspension technique modified by the authors are described in detail, and the clinical cases are listed to further illustrate the efficacy of the modified operation. The authors also compared this procedure with other common facial rejuvenation techniques.

Ferulic acid attenuates high glucose-induced apoptosis in retinal pigment epithelium cells and protects retina in db/db mice.

Background: Herein, we aimed to present evidence that Ferulic acid (FA), a phenolic acid, can alleviate high glucose (HG)-induced retinal pigment epithelium (RPE) cell apoptosis and protect retina in db/db mice.

Methods: ARPE-19 cells (a human RPE cell line) were divided into four groups: control group; HG group (30 mmol/L glucose); HG+FA group (30 mmol/L glucose and 10 mmol/L FA). Cell viability and apoptosis were detected using CCK-8 and Annexin-5 staining, respectively.

Pulse Reshaping in Double-zero-index Photonic Crystals with Dirac-like-cone Dispersion.

Triply-degenerate Dirac-like cone at the Brillouin zone center attracts much research interest in recent years. Whether the linear dispersion in such a Dirac-like cone reflects the same physics to Dirac cones at the Brillouin zone boundaries is still under investigation. In this manuscript, through microwave experiments and numerical simulations, we observe intriguing pulse reshaping phenomena in double-zero-index photonic crystals, which cannot be fully understood from their close-to-zero effective parameters.

Effect of the particle size and surface area on attachment to mineral particles in fresh water.

The objective of this study was to assess the effects of the particle size and specific surface area (SSA) on the attachment of to sediment particles. To exclude the effect of different sediment mineral compositions, pure minerals were used, and three typical suspended sediment (<62 μm) components, quartz, K-feldspar and calcite, were separated into four groups with different grain size distributions. Equilibrium attachment experiments covering common concentrations in surface water were conducted for each group.

Outcomes and possible risk factors associated with axis alignment and rotational stability after implantation of the Toric implantable collamer lens for high myopic astigmatism.

Aim: To assess the visual outcomes and possible risk factors associated with axis alignment and rotational stability after implantation of Toric implantable collamer lens (TICL) for the correction of high myopic astigmatism.

Methods: In this prospective, nonrandomized clinical study, 54 consecutive eyes of 29 patients with high myopic astigmatism received TICL implantation. To evaluate postoperative axis deviation from the intended axis, a digital anterior segment photograph was taken.
