Aims. This study investigated the association of autoantibodies binding to oxidized low-density lipoproteins (oxLDL) in diabetic retinopathy (DR). Methods. Plasma from 229 types 1 and 2 patients with DR including diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR) was analysed with ELISA-based assay to determine IgA, IgG, and IgM autoantibody levels binding to oxLDL. The c...

OBJECTIVE To investigate the role of hemoglobin (HGB) level in predicting proliferative diabetic retinopathy (PDR). METHODS We assessed 426 individuals without PDR at baseline (213 men; 213 women) from the Pittsburgh Epidemiology of Diabetes Complications Study, an 18-year prospective cohort study of childhood-onset type 1 diabetes. Presence of PDR was determined by stereo fundus photography....

PURPOSE We evaluated the relationship between long-term glycemic control and the proportion of patients developing proliferative diabetic retinopathy (PDR) among cases with mild type preproliferative diabetic retinopathy (PPDR). METHODS The relationship was evaluated between the mean hemoglobin A1C (HbA1C) value during a period of at least 2 years and the proportion of patients developing PDR...

G lial cell line–derived neurotrophic factor (GDNF) belongs to the neurotrophic factor family. GDNF functions are not restricted to neurons but are also implicated in glial cell development (1). We observed high expression levels of GDNF receptor family -component 2 (GFR 2) in epiretinal membranes (ERMs) in proliferative diabetic retinopathy (PDR), indicating the involvement of GFR 2 in ERM for...

Associations were investigated between levels of chemokines and growth factors in the vitreous and proliferative diabetic retinopathy (PDR). Enrolled were 58 patients (58 eyes) requiring pars plana vitrectomy (PPV), with PDR (n=32, none with traction retinal detachment) or not (non-PDR). In the latter, 16 had macular hole (MH) and 10 had epiretinal membrane (ERM). With a multiplex bead immunoas...

OBJECTIVE The aims of the present study were to investigate the expression and distribution of Wild-type p53-induced phosphatase 1 (Wip1) in diabetic patients with proliferative diabetic retinopathy (PDR) with epiretinal membranes (ERMs) meanwhile analyze the colocalization of Wip1 and nuclear factor kappa-B (NF-κB) p65 in ERMs. METHODS ERMs samples were collected from patients with PDR (PDR ...

PURPOSE In proliferative diabetic retinopathy (PDR) and other angiogenesis-associated diseases, increased levels of cytokines, inflammatory cells, growth factors, and angiogenic factors are present. Vascular endothelial growth factor (VEGF) appears to play a central role in mediating microvascular pathology in PDR. The purpose of the present study was to search for the association between the -...

BACKGROUND Diabetic retinopathy (DR) is a retinopathy resulting from diabetes mellitus (DM) which was classified into non-proliferative DR (NPDR) and proliferative DR (PDR). Without an early screening and effective diagnosis, patients with PDR will develop serious complications. Therefore, we sought to identify special serum microRNAs (miRNAs) that can serve as a novel non-invasive screening si...

BACKGROUND Increasing HIV pre-treatment drug resistance (PDR) levels have been observed in regions with increasing antiretroviral treatment (ART) coverage. However, data is lacking for several low/middle-income countries. We present the first PDR survey in Nicaragua since ART introduction in the country in 2003. METHODS HIV-infected, ART-naïve Nicaraguan individuals were enrolled at Roberto C...

In the last few years IC3 resp. PDR made a great stir as a SAT-based hardware verification approach without needing to unroll the transition relation as in Bounded Model Checking (BMC). Motivated by different strengths of forward and backward traversal observed in BDD based model checking, we consider Reverse PDR which starts its analysis with the initial states instead of the unsafe states as ...
