The development of a technique to induce the transformation of somatic cells to a pluripotent state via the ectopic expression of defined transcription factors was a transformational event in the field of regenerative medicine. The development of this technique also impacted ophthalmology, as patient-specific induced pluripotent stemcells (iPSCs) may be(More)
PURPOSE To study changes in corneal astigmatism and high order aberrations after clear corneal tunnel phacoemulsification guided by corneal topography. METHODS All patients were randomly assigned to the test group or the control group. Corneal topography-guided clear corneal tunnel phacoemulsification followed by intraocular lens (IOL) implantation was(More)
A new method based on pressurised liquid extraction (PLE) followed by liquid chromatography-triple quadrupole linear ion trap mass spectrometry (LC-QTrap-MS) analysis has been developed for the identification and quantification of four major alkaloids in extracts of Corydalis decumbens (Thunb.) Pers. PLE extractions were performed using 90% ethanol;(More)
Lignocellulosic biomass has been identified as an economic and environmental feedstock for future biotechnological production. Here, for the first time, poly-(γ-glutamic acid) (PGA) production by Bacillus subtilis NX-2 using rice straw is investigated. Based on two-stage hydrolysis and characteristic consumption of xylose and glucose by B. subtilis NX-2, a(More)
PURPOSE High prevalence of pseudoexfoliation syndrome (PEX) occurs in the Uighur population. This study investigated DNA methylation of the lysyloxidase-like 1 (LOXL1) gene in Uighur PEX patients with cataracts. METHODS The research involved 10 lens capsule specimens from Uighur PEX patients with cataracts and 10 lens capsule specimens from Uighur control(More)
OBJECTIVE To investigate tear-film break-up time and spatial distribution via noninvasive Keratograph 4 in patients with cataracts and dry eye syndrome (DES). METHODS Noninvasive first break-up time (NIKf-BUT) and average break-up time (NIKav-BUT) were evaluated via Keratograph 4 in patients with age-related cataracts and DES. The location and size of(More)
Our previous study identified five new heat shock factor 4 (HSF4) mutations in 150 age-related cataract (ARC) patients which indicated that HSF4 mutations may be associated with this disease. Hypoxia-inducible factor (Hif1α) is an important downstream target of HSF4b. It has been found that Hif1α play also important roles in cataract development. To(More)
The production of poly-γ-glutamic acid (γ-PGA) by Bacillus subtilis NX-2 using a moving bed biofilm reactor (MBBR) system was tested for the first time in this study. Polypropylene TL-2 was chosen as a suitable carrier, and γ-PGA concentration of 42.7±0.86g/L and productivity of 0.59±0.06g/(Lh) were obtained in batch fermentation. After application of the(More)
AIM The aim of this study was to evaluate the long-term visual outcomes and factors affecting visual results in children undergoing secondary intraocular lens (IOL) implantation following primary congenital cataract extraction. METHODS Children with congenital cataracts who underwent secondary IOL implantation for aphakia at the Eye and ENT Hospital of(More)
PURPOSE Congenital cataracts account for about 10% of cases of childhood blindness. Heat shock transcription factor 4 (HSF4) is related with human autosomal dominant lamellar and Marner cataracts; a T→C transition at nucleotide 348 was found in a large Chinese cataract family. The aim of this study was to analyze the unique role of HSF4b and the mutation of(More)
