background: patients with transfusional iron overload have depended on iron chelation therapy and improving chelation regimens have been of the highest priority. the aim of this study was to compare effect of combined versus monotherapy with deferoxamine (dfo) and deferiprone (dfp) in iron overloaded beta thalassemia (bt) major patients materials and methods we studied 36 bt major patients (mea...
Certain organophosphorus esters such as diisopropylfluorophosphate (DFP) cause delayed neuropathy by inhibition of neuropathy target esterase (NTE) keeping neuron in normal function. In this study, effects of neurobion alone and in combination with dexamethasone on DFP–induced delayed neuropathy were evaluated. Thirty-five mice were divided to five groups that each group consists 7 mice. Except...
To investigate the fluorination influence on the photovoltaic performance of small molecular based organic solar cells (OSCs), six small molecules based on 2,1,3-benzothiadiazole (BT), and diketopyrrolopyrrole (DPP) as core and fluorinated phenyl (DFP) and triphenyl amine (TPA) as different terminal units (DFP-BT-DFP, DFP-BT-TPA, TPA-BT-TPA, DFP-DPP-DFP, DFP-DPP-TPA, and TPA-DPP-TPA) were synth...
Background Combination therapy with deferipron and desferrioxamine (DFP+DFO) seems more effective than DFP and DFO in monotherapy in removing myocardial iron. However, no data are available in literature about prospective comparisons on cardiac iron and function in TM patients treated with DFP+DFO versus DFP and DFO in monotherapy. Aim: The aim of this multi-centre study was to assess prospecti...
It has been previously shown that the esterase and proteinase activities of trypsin and chymotrypsin (1, 2) were equally inhibited by diisopropyl fluorophosphate (DFP) (3). With chymotrypsin, 50 per cent inhibition occurred when 0.55 mole of inhibitor per mole of enzyme1 was used at pH 7.7. On the basis of a linear relationship between the-per cent inhibition and the concentration of DFP, 1.1 m...
PURPOSE To investigate the retinal-protective effects of the oral iron chelator deferiprone (DFP) in mice lacking the iron regulatory hormone hepcidin (Hepc). These Hepc knockout (KO) mice have age-dependent systemic and retinal iron accumulation leading to retinal degeneration. METHODS Hepc KO mice were given DFP in drinking water from age 6 to 18 months. They were then compared to Hepc KO m...
Exposure to high levels of organophosphorus compounds (OP) can induce status epilepticus (SE) in humans and rodents via acute cholinergic toxicity, leading to neurodegeneration and brain inflammation. Currently there is no treatment to combat the neuropathologies associated with OP exposure. We recently demonstrated that inhibition of the EP2 receptor for PGE2 reduces neuronal injury in mice fo...
Digital fringe projection (DFP) techniques provide dense 3D measurements of dynamically changing surfaces. Like the human eyes and brain, DFP uses triangulation between matching points in two views of the same scene at different angles to compute depth. However, unlike a stereo-based method, DFP uses a digital video projector to replace one of the cameras(1). The projector rapidly projects a kn...
Organophosphate (OP) exposure can be lethal at high doses while lower doses may impair performance of critical tasks. The ability to predict such effects for realistic exposure scenarios would greatly improve OP risk assessment. To this end, a physiologically based model for diisopropylfluorophosphate (DFP) pharmacokinetics and acetylcholinesterase (AChE) inhibition was developed. DFP tissue/bl...
BACKGROUND Due to the limited data available in literature, the aim of this multi-centre study was to prospectively compare in thalassemia major (TM) patients the efficacy of combined deferiprone (DFP) and deferoxamine (DFO) regimen versus either DFP and DFO in monotherapy by cardiovascular magnetic resonance (CMR) over a follow up of 18 months. METHODS Among the first 1135 TM patients in the...
