Standard cross-linking versus photorefractive keratectomy combined with accelerated cross-linking for keratoconus management: a comparative study. [PDF]

Acta Ophthalmol, 2019
AbstractPurposeTo compare the safety and efficacy of standard 30 min epithelium‐off cross‐linking (CXL) versus photorefractive keratectomy (PRK) combined with accelerated epithelium‐off cross‐linking (AXL) for the treatment of progressive keratoconus (CXL‐Plus).MethodsThis study was a prospective multicentre comparative clinical study.

Accelerated vs. conventional collagen cross‑linking for infectious keratitis

Experimental and Therapeutic Medicine, 2021
Infectious keratitis represents a serious concern for ophthalmologists, with a progressively growing incidence in the last few years. In this prospective comparative study, we evaluated two groups of patients with infectious keratitis or corneal ulcer resistant to antimicrobial and antifungal therapy, treated respectively with conventional and ...

Correlation between changes in corneal asphericity and progression of keratoconus in children

Journal of the Egyptian Ophthalmological Society, 2022
Clinical relevance Early detection of keratoconus (KC) progression and timing for retreatment. Background Q value (coefficient of corneal asphericity) reflects the shape of the cornea, its refractive power, and spherical aberration.

Voltage Sensing in Bacterial Protein Translocation [PDF]

, 2020
The bacterial channel SecYEG efficiently translocates both hydrophobic and hydrophilic proteins across the plasma membrane. Translocating polypeptide chains may dislodge the plug, a half helix that blocks the permeation of small molecules, from its ...

Accelerated (45 mW/cm2) Transepithelial Corneal Cross-Linking for Progressive Keratoconus Patients: Long-Term Topographical and Clinical Outcomes

Frontiers in Medicine, 2020
Aims: We characterized long-term clinical outcomes of accelerated (45 mW/cm2) transepithelial corneal cross-linking (ATE-CXL) for the treatment of progressive keratoconus.Methods: Forty-two eyes from 37 patients treated for keratoconus were observed. ATE-

Structural corneal changes identified with the use of confocal microscopy after accelerated CXL for keratoconus

Journal of Ophthalmology, 2020
Background: Post-crosslinking (CXL) biomicroscopic changes in patients with keratoconus can be detected by confocal microscopy. Few studies reported on morphological changes in the cornea after CXL.

Recent advances in corneal collagen cross-linking

Indian Journal of Ophthalmology, 2017
Corneal collagen cross-linking has become the preferred modality of treatment for corneal ectasia since its inception in late 1990s. Numerous studies have demonstrated the safety and efficacy of the conventional protocol.

Testing three hypotheses about effects of sensitive-insensitive parenting on telomeres. [PDF]

, 2020
Telomeres are the protective DNA-protein sequences appearing at the ends of chromosomes; they shorten with each cell division and are considered a biomarker of aging.
