In the current study we undertook a series of experiments to test the hypothesis that a monogenic cause of disease may be detectable within a cohort of Finnish young onset Parkinson's disease patients. In the first instance we performed standard genome wide association analyses, and subsequent risk profile analysis. In addition we performed a series of analyses that involved testing measures of...
Background and objective: The nested case-control study has become popular as an efficient alternative to the full-cohort design. This study compares the results of a nested case-control analysis approach with the full cohort analysis. Methods: A cohort of 276 subjects (new cases from a TB registry) was used for this study. Cox Regression model was used for the full cohort analysis. In orde...
BACKGROUND Diffuse large B-cell lymphoma is a clinically and molecularly heterogeneous disease. Gene expression profiling studies have shown that the tumor microenvironment affects survival and that the angiogenesis-related signature is prognostically unfavorable. The contribution of histopathological microvessel density to survival in diffuse large B-cell lymphomas treated with immunochemother...
Ultrasound cycloplasty: a case series examining the efficacy on a local Malaysian cohort of patients
Introduction: Ultrasound cycloplasty (UCP) is commercially available in Europe. It has been shown to have less side effects than its trans-scleral diode laser cyclophotocoagulation counterpart reducing intraocular pressure (IOP) refractory glaucoma patients.
