Evaluation of Permeate Quality in Pilot Scale Membrane Distillation Systems
2019
In this work, the salinity of permeate obtained with membrane distillation (MD) in pilot scale systems was analyzed. Experiments were performed with three different spiral-wound commercial modules, one from Solar Spring with 10 m2 surface membrane area and two from Aquastill with 7.2 and 24 m2. Intermittent operation meant that high permeate conductivity was measured in the beginning of each experiment, which was gradually decreasing until reaching a constant value (3&ndash
Pilot Study on Predictive Value of Plasmatic Levels of 9 Angiogenetic Biomarkers in Selection of Patients Candidate to Prostate Biopsy
2013
To reduce the number of negative prostate biopsies in patients with elevated PSA serum levels represents a major challenge in urological oncology. Angiogenetic factors might be involved in initial stages of prostate cancer and might represent useful tools in patients’ selection for prostate biopsy. The plasmatic levels of Angiopoietin-2, Follistatin, G-CSF, HGF, IL-8, Leptin, PDGF-BB, PECAM-1 and VEGF were measured by BioPlex immunoassay in patients undergoing prostate biopsy for palpable prostate nodule and/or elevated PSA levels (≥4 ng/mL). They were related with biopsy results. ROC curve analysis was exploited to test the diagnostic accuracy of each biomarker by AUC calculation. A poten…
Optimal Control of Dissipative Quantum Systems
2008
We study the control of finite dimensional quantum systems by external laser fields. After examining the concrete example of the diatomic molecular alignment in dissipative media, we are interested in the problem of optimal control, where the objective is to bring the system from an initial state into a given final state while minimizing a cost functional. The Pontryagin maximum principle (PMP) provides necessary conditions for optimality, by establishing that any optimal trajectory is the extremal solution of an extended problem of Hamiltonian structure. In this context, we perform the analysis of two particular systems. The first one is a dissipative 2-level system, for which we determine…
Circulating levels of 3-hydroxymyristate, a direct quantification of endotoxaemia in noninfected cirrhotic patients
2019
IF 4.5; International audience; Background & AimsThe quantification of lipopolysaccharide (LPS) in biological fluids is challenging. We aimed to measure plasma LPS concentration using a new method of direct quantification of 3‐hydroxymyristate (3‐HM), a lipid component of LPS, and to evaluate correlations between 3‐HM and markers of liver function, endothelial activation, portal hypertension and enterocyte damage.MethodsPlasma from 90 noninfected cirrhotic patients (30 Child‐Pugh [CP]‐A, 30 CP‐B, 30 CP‐C) was prospectively collected. The concentration of 3‐HM was determined by high‐performance liquid chromatography coupled with mass spectrometry.Results3‐HM levels were higher in CP‐C patien…

Mitochondrial and redox dysfunction in post-menopause as risk factor of neurodegenerative disease: a pilot study testing the role of a validated Japa…
2020
During the menopause women may experience increased oxidative stress and decreased antioxidant capacity and, together with the decline of neurosteroids, this represents a risk factor for Alzheimer's disease. The aim of the present study was to test a functional food (FPP-ORI, Osato Research Institute, Gifu, Japan) on redox and mitochondrial efficiency in post-menopausal women. The study population consisting of 69 untreated post-menopausal women were given supplements as follows: Group A was given a multivitamin (MV) 1c 2 times a day, and group B was given FPP 4.5 g 2 times a day. Group C consisted of 23 fertile premenopausal women as the control group. The tests carried out on entry, and a…
The role of macrophage colony-stimulating factor in patients with acute myocardial infarction: a pilot study.
2011
We assessed whether macrophage colony-stimulating factor (M-CSF) levels are associated with left ventricular systolic dysfunction (LVSD) in patients with acute myocardial infarction (AMI). We studied 56 patients with AMI (mean age: 67 ± 12 years) and identified those with clinical (Killip class >II) or echocardiographic signs (ejection fraction ≤45%) of LVSD. We evaluated the established cardiovascular risk factors and measured several cardiovascular biomarkers, including M-CSF. Serum M-CSF concentrations (pg/mL) were significantly increased in patients with both clinical and echocardiographic signs of LVSD (460 ± 265 vs 290 ± 210, P = .0103 and 493 ± 299 vs 287 ± 174, P = .0028, respec…
Corporeal Compression at the Onset of Septic shock (COCOONs): a compression method to reduce fluid balance of septic shock patients
2019
AbstractFluid overload in septic intensive care unit (ICU) patients is common and strongly associated with poor outcome. There is currently no treatment for capillary leak, which is mainly responsible for high positive fluid balance (FB) in sepsis. We hypothesized that increasing interstitial pressure with extensive corporeal compression would reduce FB. The objective of this study was to evaluate the feasibility, efficacy, and safety of a compression treatment during sepsis. This pilot, two-center, single-arm trial enrolled critically ill, non-surgical, septic patients receiving mechanical ventilation. The therapeutic intervention was the early application of compression bandages on more t…
