Two-year topographic and densitometric outcomes of accelerated (45 mW/cm2) transepithelial corneal cross-linking for keratoconus: a case-control study

BMC Ophthalmology, 2018
Background Conventional corneal cross-linking is effective for retarding the progression of keratoconus. However the long-term efficacy and safety of accelerated (45 mW/cm2) transepithelial corneal cross-linking (ATE-CXL) on progressive keratoconus (KC ...

One-year natural course of corneal densitometry in high myopic patients after implantation of an implantable collamer lens (model V4c)

BMC Ophthalmology, 2020
Background Corneal densitometry, which is also known as corneal backscattering, is a surrogate measure of corneal clarity. The purpose of the study was to investigate the changes in corneal densitometry (CD) after implanting an implantable collamer lens (

Expression characteristics of dual‐specificity phosphatase 2 and hypoxia‐inducible factor‐1α in acute kidney injury and preliminary study of the effect of dual‐specificity phosphatase 2 on HK‐2 cells

Experimental Physiology, EarlyView.
ABSTRACT Acute kidney injury (AKI) is a global health problem with significant long‐term harm if the prognosis is poor. Dual‐specificity phosphatase 2 (DUSP2) is involved in key regulatory pathways in several disease processes, but its function in renal pathophysiology is unclear.
