Purpose: To study the benefits of Directional Bremsstrahlung Splitting (DBS) dose variance reduction technique in BEAMnrc Monte Carlo (MC) code for Oncor® linac at 6MV and 18MV energies. Materials and Method: A MC model of Oncor® linac was built using BEAMnrc MC Code and verified by the measured data for 6MV and 18MV energies of various field sizes. Then Oncor® machine was modele...

Traumatic cataract was induced in rat and rabbit. The progression of the posterior subcapsular cataract and the wound healing were followed by quantitative microradiography. This method makes it possible to determine the dry mass content and to calculate the refractive indices in the lens. In the injured rat lens a reduced dry mass concentration was determined in both the wound region and the p...

  Lens development requires precise interaction between cranial surface ectoderm, Neuroectoderm and interposed mesenchyme. Cell surface glycoconjugate and extracellular matrix govern lens morphogenesis. The aim of the present study was to investigate the presence and distribution of Glycoconjugate and extracellular matrix components.   Embryos from day 11-20 of gestation from whistar rat were c...

We evaluated the effect of an aldose reductase inhibitor, fidarestat, on diabetic retinopathy (DR) and cataract in spontaneously diabetic Torii (SDT) rats. Four rat groups were included: untreated, lowand high-dose (8 and 32 mg/kg/day) fidarestat-treated SDT rats, and nondiabetic control Sprague-Dawley rats. DR and cataract were evaluated and retinal and lens sorbitol, reduced glutathione (GSH)...

BACKGROUND Contact lens-related infections are often associated with inadequate contact lens hygiene, and therefore, contact lens care products should be able to sufficiently minimise the amount of pathogens that are responsible for these infections. In 2001, the EN ISO 14729 was introduced to ensure adequate disinfection efficacy of contact lens care solutions, but this norm has recently been ...

background: calcineurin inhibitors (cni) have significantly reduced the incidence of acute rejection. nephrotoxicity however may contribute to long-term allograft dysfunction. mycophenolate mofetil (mmf) may allow cyclosporine (csa) dose reduction without increasing the risk of rejection. methods: in seventy-eight living unrelated kidney transplant patients with renal dysfunction, we studied th...

The differential diagnoses for phacolytic glaucoma are acute angle closure glaucoma, open angle glaucoma with uveitis, neovascular glaucoma, and glaucoma secondary to trauma. We report an unusual case where the dislocated cataractous lens firmly adherent to the corneal endothelium evoked a cellular reaction similar to phacolytic glaucoma but clinically appeared like a deep corneal abscess. The ...

In the article “Contact Lens-Assisted Collagen CrossInking (CACXL): A New Technique for Cross-Linking Thin Corneas” by Jacob et al.,1 the authors proposed a contact lens for extra protection of corneal collagen cross-linking (CXL) in thin corneas (range: 350 to 498 μm; mean: 377 μm). In their study, the treated corneas are protected by the contact lens and riboflavin (B2). I intend to provide a...
