We derive theoretically the power division ratio (PDR) on multi-hop wireless power transfer (WPT) to two receivers coupling with two couplers. The derived expression suggests that the PDR can be controlled by adjusting the load resistance. However, the control range of PDR by adjusting the load resistance of one receiver is limited when a hop count to that receiver is odd number. Therefore we s...

PURPOSE To identify the protein profiles in vitreous associated with retinal fibrosis, angiogenesis, and neurite formation in epiretinal fibrovascular membranes (FVMs) in patients with proliferative diabetic retinopathy (PDR). METHODS Vitreous samples of 5 non-diabetic control patients with vitreous debris and 7 patients with PDR membranes were screened for 507 preselected proteins using the ...

OBJECTIVE Proliferative diabetic retinopathy (PDR) is characterized by a progressive visual impairment in young people. Human leucocyte antigen (HLA)-A24 is a well-established factor associated with the pancreatic islets of Langerhans lost in this process. Our aim was to study further the relationship of the HLA-A24 associated with PDR. MATERIALS AND METHODS We evaluated a group of patients w...

BACKGROUND/AIMS Proliferative diabetic retinopathy (PDR) is a severe blinding condition. We investigated whether retinal metabolism, measured by retinal oximetry, may predict PDR activity after panretinal laser photocoagulation (PRP). METHODS We performed a prospective, interventional, clinical study of patients with treatment-naive PDR. Wide-field fluorescein angiography (OPTOS, Optomap) and...

OBJECTIVE There is growing evidence to indicate that somatostatin could be added to the list of natural antiangiogenic factors that exist in the vitreous fluid. In addition, a deficit of intravitreous somatostatin-like immunoreactivity (SLI) has been found in diabetic patients with proliferative diabetic retinopathy (PDR). In the present study, we have determined the main molecular variants of ...

PURPOSE To determine levels of the chemokines CCL1/I-309, CCL2/MCP-1, CCL3/MIP-1alpha, CCL4/MIP-1beta, CCL7/MCP-3, CCL8/MCP-2, CXCL5/ENA-78, CXCL6/GCP-2, CXCL10/IP-10, and CXCL11/I-TAC in the vitreous humor and serum, from patients with proliferative diabetic retinopathy (PDR), proliferative vitreoretinopathy (PVR), and rhegmatogenous retinal detachment with no PVR (RD), and to investigate the ...

Splanchnic ischaemia and hepatic dysfunction are severe complications after coronary artery bypass grafting (CABG) and lead to increased morbidity and mortality. Non-invasive determination of the indocyanine green (ICG) plasma disappearance rate (PDR) offers an opportunity for the early diagnosis of hepato-splanchnic hypoperfusion. The aim of this study was to establish the postoperative time c...

BACKGROUND Hepatic impairment is found in up to 20 % in critically ill patients. Hypoxic/ischemic hepatitis (HH) is a diffuse hepatic damage associated with high morbidity and mortality. Indocyanine green plasma disappearance rate (ICG-PDR) is an effective tool assessing liver function in acute and chronic hepatic diseases. Aim of this study was to evaluate the prognostic impact of ICG-PDR in c...

BACKGROUND The aim of this study was to determine retinal outcomes in patients with proliferative diabetic retinopathy (PDR) presenting during pregnancy or within the first year postpartum. METHODS All patients with diabetes mellitus during pregnancy from 1992 through 2002 were included. Medical records were reviewed and data including obstetric history, pregnancy outcome, other medical compl...
