Although post-treatment has been regarded as one of the effective ways to passivate the underlying defects in perovskite solar cells (PSCs), little attention has been paid to how to select suitable passivation agents. Here, we report on the dependence of photovoltaic performance on acid dissociation constant (Ka) of passivation agents to guide a criterion for selecting passivation agents in PSCs. Power conversion efficiency (PCE) is increased after post-treatment with high-pKa (10.6) cyclohexyla

The development of secondary MHs after vitrectomy is rare. Pathogenic mechanisms other than idiopathic MH may be involved in these cases. The anatomical and functional outcome of the secondary MHs that developed after vitrectomy was good, although the final visual acuity was dependent on the underlying ocular pathology.

Spectral OCT/SLO equipped with a test-retest function showed excellent reproducibility with regard to RNFL thickness measurements. The severity of glaucoma did not affect the reproducibility. These findings suggest that spectral OCT/SLO fulfills one of the basic premises for the diagnosis and progression analysis of glaucoma.

There has been no report about hereditary and clinical features of retinitis pigmentosa (RP) in Koreans. To evaluate these, data were collected from 365 RP patients including age, gender, visual acuity (VA), spherical equivalent (SE) of refractive errors, funduscopic findings, color vision test, visual field score (VFS) obtained from Goldmann perimetry, and the inheritance patterns from pedigrees. Simplex RP was the most common inheritance pattern (61.9%); followed by autosomal recessive RP (17.

This retrospective review of ULMFF showed that nonsurgical treatment is usually unsuccessful, and early single-level anterior arthrodesis has a favorable outcome. However, exclusive two-level stabilization or pedicle screw fixation needs to be considered in the separation type.

Previously, the perivascular characteristics of dental pulp stem cells (DPSCs) were reported, which suggested the potential application of DPSCs as perivascular cell source. In this study, we investigated whether DPSCs had angiogenic capacity by coinjection with human umbilical vein endothelial cells (HUVECs) in vivo; in addition, we determined the role of stromal cell-derived factor 1- α (SDF-1 α ) and C-X-C chemokine receptor type 4 (CXCR4) axis in the mutual interaction between DPSCs and HUVE

<b>Purpose:</b> To investigate the incidence and risk factors of postoperative dysphagia after anterior cervical decompression and fusion (ACDF) in terms of demographic, procedural and anaesthetic perspectives.<b>Materials and methods:</b> Medical records and radiologic data of patients who underwent anterior cervical surgery performed by two surgeons in a single centre between January 2012 and December 2015 were retrospectively analysed. Patients with spinal tumours, infective spondylitis and t

Cyclosporine combined with corticosteroids or other immunosuppressive drugs as needed is an effective treatment for noninfectious uveitis, thus minimizing the adverse effects of corticosteroids and other toxic drugs. However, careful monitoring for the toxicity of cyclosporine is needed, because a small group of patients cannot tolerate its toxicity.

Stem cell-based therapeutics are amongst the most promising next-generation therapeutic approaches for the treatment of spinal cord injury (SCI), as they may promote the repair or regeneration of damaged spinal cord tissues. However, preclinical optimization should be performed before clinical application to guarantee safety and therapeutic effect. Here, we investigated the optimal injection route and dose for adult human multipotent neural cells (ahMNCs) from patients with hemorrhagic stroke us
