OBJECTIVE To describe the early results of penetrating keratoplasty (PKP) in patients who had previously undergone cultivated limbal epithelium transplantation. METHODS Medical records of patients with limbal stem cell deficiency due to chemical burns who underwent PKP after cultivated limbal epithelium transplantation were reviewed for demographics, primary etiology, type of limbal transplan...

BACKGROUND Fungal keratitis is basically treated by medications. Several cases of fungal keratitis were reported around the world to have been treated successfully by corneal graft--penetrating keratoplasty (PKP). Studies have shown that PKP is a useful treatment, preserves eye globe integrity, and rehabilitates vision in patients with advanced fungal keratitis. AIM To study the use of penetr...

PURPOSE To survey the changes in indications for penetrating keratoplasty (PKP) and re-evaluate the risk factors for allograft rejection and graft failure. METHODS We evaluated the records of 396 eyes of 335 patients who had undergone PKP at the Tokyo University Hospital between 1987 and 1997. Clinical results were analyzed by the Kaplan-Meier life table method and the log-rank test. RESULT...

PURPOSE To perform a retrospective study to evaluate the long-term outcome of systemic cyclosporine treatment as an adjunct to topical corticosteroid treatment after penetrating keratoplasty (PKP). METHODS Twenty-six high-risk patients (27 eyes) who received systemic cyclosporine following PKP for an average of 5.4 months were compared with another series of 57 patients (57 eyes) who did not ...

Bacterial metabolism of polysaccharides from plant detritus into acids and solvents is an essential component of the terrestrial carbon cycle. Understanding the underlying metabolic pathways can also contribute to improved production of biofuels. Using a metabolomics approach involving liquid chromatography-mass spectrometry, we investigated the metabolism of mixtures of the cellulosic hexose s...

BACKGROUND To report a patient with penetrating keratoplasty (PKP) graft endothelial failure implanted with toric intraocular lens (IOL) who was treated with Descemet stripping endothelial keratoplasty (DSAEK). CASE PRESENTATION A 40 year old male patient implanted with toric intraocular lens for the treatment of post PKP astigmatism, presented for the treatment of graft endothelial failure'....

The ocular characteristics and responses were examined in patients who had undergone extracapsular cataract extraction (ECCE), intracapsular cataract extraction (ICCE) and penetrating keratoplasty (PKP) in one eye only. In each of the three groups, corneal sensitivity (the inverse of corneal touch threshold), oxygen uptake rate, and endothelial cell density were lower in the operated eye than i...

BACKGROUND The aim of this study was to evaluate the feasibility of treating vertebral compression fractures using an autonomously developed nitinol memory alloy vertebral stent. MATERIAL AND METHODS Thoracolumbar vertebral specimens from adult human cadavers were made into models of compression fractures. The models were divided into group A, which received percutaneous kyphoplasty (PKP), ba...

Despite the growing number of studies that underlie influence between perceived overqualification (POQ) and counterproductive behaviour (PKP), there is still a gap in lack research involving role affective mechanisms on effect POQ PKP. In this study, researchers focused mediating job boredom (KTP) pathway Using sample 106 employees lecturers at Islamic universities Indonesia using integration t...
