Functionalized halloysite nanotubes for enhanced removal of lead(II) ions from aqueous solutions

2018

In this study, environmental friendly halloysite nanotubes and their amino derivatives were used as adsorbent materials for lead(II) ions. The adsorption ability of both nanomaterials towards Pb2+ ions has been studied in NaClaq, at I = 0.1 mol L−1, in the pH range 3–6. Moreover, the effect of ionic strength on the adsorption process was evaluated at the pH of maximum efficiency of the adsorbent materials. Kinetic and equilibrium experiments were carried out by using the Differential Pulse Anodic Stripping Voltammetry (DP-ASV) technique to check the metal ion concentration in solution after contact with the two adsorbents. Different isotherm and kinetic equations were used to fit the experi…

Polymerization reactions and modifications of polymers by ionizing radiation

2020

International audience; Ionizing radiation has become the most effective way to modify natural and synthetic polymers through crosslinking, degradation, and graft polymerization. This review will include an in-depth analysis of radiation chemistry mechanisms and the kinetics of the radiation-induced C-centered free radical, anion, and cation polymerization, and grafting. It also presents sections on radiation modifications of synthetic and natural polymers. For decades, low linear energy transfer (LLET) ionizing radiation, such as gamma rays, X-rays, and up to 10 MeV electron beams, has been the primary tool to produce many products through polymerization reactions. Photons and electrons in…

Stress proteins HSP90 and Gp96 in graft-versus-host disease : pathophysiological, diagnostic and therapeutic implication

2015

Allogeneic hematopoietic cell transplantation is a treatment for certain disorders including hematologic malignancies. Graft-versus-host-disease (GvHD) is a major, life-threatening complication. It is due to the recognition of recipient antigens by donor T cells, which activate and damage tissues. Intestinal barrier alteration plays a critical role in GvHD. Heat shock proteins (HSP)90 include five members, three cytosolic members named HSP90, and one member localized in endoplasmic reticulum (ER) called Gp96 and able to gain extracellular level in case of stress. We show in our thesis that 17AAG, a HSP90 inhibitor, reduces GvHD mortality in a mouse model. This effect is associated with an i…

Antilymphocyte Globulin for Prevention of Chronic Graft-versus-Host Disease.

2016

Clinical Trial, Phase III; Journal Article; Multicenter Study; Randomized Controlled Trial; Research Support, Non-U.S. Gov't; BACKGROUND Chronic graft-versus-host disease (GVHD) is the leading cause of later illness and death after allogeneic hematopoietic stem-cell transplantation. We hypothesized that the inclusion of antihuman T-lymphocyte immune globulin (ATG) in a myeloablative conditioning regimen for patients with acute leukemia would result in a significant reduction in chronic GVHD 2 years after allogeneic peripheral-blood stem-cell transplantation from an HLA-identical sibling. METHODS We conducted a prospective, multicenter, open-label, randomized phase 3 study of ATG as part of …

2021

Background We aimed to compare the performance of the recent CASTLE score to J-CTO, CL and PROGRESS CTO scores in a comprehensive database of percutaneous coronary intervention of chronic total occlusion procedures. Methods Scores were calculated using raw data from 1,342 chronic total occlusion procedures included in REBECO Registry that includes learning and expert operators. Calibration, discrimination and reclassification were evaluated and compared. Results Mean score values were: CASTLE 1.60±1.10, J-CTO 2.15±1.24, PROGRESS 1.68±0.94 and CL 2.52±1.52 points. The overall percutaneous coronary intervention success rate was 77.8%. Calibration was good for CASTLE and CL, but not for J-CTO…

Growth Differentiation Factor-15 (GDF-15) Levels Are Associated with Cardiac and Renal Injury in Patients Undergoing Coronary Artery Bypass Grafting …

2014

International audience; Objective: Growth differentiation factor-15 (GDF-15) has been identified as a strong marker of cardiovascular disease; however, no data are available concerning the role of GDF-15 in the occurrence of organ dysfunction during coronary artery bypass grafting (CABG) associated with cardiopulmonary bypass (CPB). Methods: Five arterial blood samples were taken sequentially in 34 patients from anesthesia induction (IND) until 24 h after arrival at the intensive care unit (ICU). Plasma levels of GDF-15, follistatin-like 1 (FLST1), myeloperoxidases (MPO), hydroperoxides and plasma antioxidant status (PAS) were measured at each time-point. Markers of cardiac (cardiac-troponi…

Late carotid artery stent erosion and pseudoaneurysm after accidental hyperextension of the neck

2010

A 75-year-old man was referred to our unit complaining of a large pulsatile neck mass that appeared 2 days after an accidental fall and hyperextension of the neck. One month earlier, he was submitted to left carotid artery stenting for symptomatic high-grade stenosis. His medical history included diabetes mellitus, coronary artery disease, and a right femoropopliteal bypass for critical limb ischemia. At the time of admission, he was afebrile and had no evidence of local erythema, draining sinus, or leukocytosis. Moreover, C-reactive protein was 1 mg/dL. The clinical examination revealed a large swelling in the region of the left carotid bifurcation and mild dyspnea. Arterial duplex imaging…

Preliminary evaluation of near-infrared vein visualization technology in the screening of palatal blood vessels.

2018

Background Avoidance from palatal blood vessel rupture is a major concern during the palatal soft tissue graft surgery. There is no defined chair-side and case-specific palatal blood vessel detection approach to facilitate the harvesting process. The objective of this pilot study is to assess the feasibility of a near-infrared vein visualization system in the screening process of palatal blood vessels. Material and Methods An extraoral vein visualization device (AccuVein AV400) was applied to a total of 304 hemi-maxilla of 152 individuals by two blind examiners. The study groups were classified according to their maximum inter-incisal measurements. The distances between the coronal border o…
