Partition of volatile compounds in pea globulin–maltodextrin aqueous two-phase system

2014

International audience; This study is based on the assumption that the off-flavour of pea proteins might be decreased using the retention of volatile compounds by a mixture with another biopolymer. The partition of volatile compounds in an aqueous system containing pea protein and maltodextrins was followed under thermodynamic incompatibility conditions. Firstly, the phase diagram of the system was established. Then, the partition of aroma compounds between the phase rich in protein and the phase rich in maltodextrin was measured by SPME–GC–MS. There was a transfer of volatile compounds during phase separation. Variations of pH were also used to vary the retention of volatile compounds by p…

Maltose-conjugated chitosans induce macroscopic gelation of pectin solutions at neutral pH

2014

Injectable polymer scaffolds are particularly attractive for guided tissue growth and drug/cell delivery with minimally invasive intervention. In the present work, "all-polymeric" gelling systems based on pectins and water-soluble maltose-conjugated chitosans (CM) have been developed. Maltose-conjugated chitosan has been synthesized at three different molar ratios, as evaluated by FITR analysis and fluorimetric titration. A thorough rheological characterization of the blends and their parent solutions has been performed. Macroscopic gelation has been achieved by mixing the high esterification degree pectins with CM at higher maltose grafted to chitosan contents. Gels form in a few minutes a…

Extraction, Characterization and Incorporation of Hypericum scruglii Extract in Ad Hoc Formulated Phospholipid Vesicles Designed for the Treatment of…

2020

An extract of Hypericum scruglii, an endangered endemic plant of Sardinia (Italy), was prepared and characterized. It was loaded in special phospholipid vesicles, glycerosomes, which were modified by adding maltodextrin (glucidex) and a polymer (gelatin or hyaluronan). The corresponding liposomes were also prepared and used as reference. The vesicles disclosed suitable physicochemical features for skin delivery. Indeed, their mean diameter ranged from 120 to 160 nm, they were homogeneously dispersed (polydispersity index &le

Evaluación de los niveles plasmáticos de hepcidina en pacientes con anemia ferropénica y cáncer colorectal

2017

RESUMEN TESIS DOCTORAL TITULO: “Evaluación de los niveles plasmáticos de hepcidina en pacientes con anemia ferropénica y cáncer colorectal.” AUTOR: María Vila Montañés INTRODUCCIÓN El objetivo general de este trabajo fue determinar los niveles plasmáticos de hepcidina y su posible relación con el tratamiento con hierro intravenoso. El hierro es una terapia clave en el manejo de la anemia preoperatoria en los pacientes con cáncer colorectal. La anemia preoperatoria es una entidad prevalente en los pacientes con cáncer de colon, especialmente en los que están pendientes de intervención quirúrgica. Sus efectos nocivos han sido estudiados y actualmente se considera factor de riesgo de morbilida…

Cambios en el contenido miocárdico de hierro tras la administración de hierro intravenoso (Myocardial-IRON)

2021

Introducción: El tratamiento con hierro carboximaltosa (FCM) intravenoso (iv) ha mostrado mejorar los síntomas, capacidad funcional y calidad de vida, y reducir los ingresos por insuficiencia cardiaca (IC), en los pacientes con IC, fracción de eyección deprimida y déficit de hierro (DH). Sin embargo, los mecanismos subyacentes que expliquen estos beneficios siguen siendo inciertos. Asimismo, las secuencias de resonancia magnética cardiaca (RMC) T2* y T1 mapping, permiten cuantificar el contenido miocárdico de hierro y valores más bajos indican mayor concentración de hierro en el miocardio. Objetivo: El objetivo primario del estudio fue cuantificar mediante las secuencias de RMC T2* y T1 map…

Short‐term changes in left and right systolic function following ferric carboxymaltose: a substudy of the Myocardial‐IRON trial

2020

Funding: This work was supported in part by an unrestricted grant from Vifor Pharma and Proyectos de Investigación de la Sección de Insuficiencia Cardiaca 2017 from Sociedad Española de Cardiología. The mechanisms underlying the beneficial effect of ferric carboxymaltose (FCM) in patients with heart failure (HF) and iron deficiency (ID) have not been completely characterized. The Myocardial-IRON trial was a double-blind, randomized trial that evaluated myocardial iron repletion following FCM vs. placebo in 53 patients with HF and ID. In this post hoc analysis, we evaluated whether treatment with FCM was associated with cardiac magnetic resonance changes in left and right ventricular functio…

P255 Efficacy and safety of a restrictive ferric carboxymaltose infusion strategy for iron deficiency anemia in inflammatory bowel disease patients

2021

Abstract Background Iron deficiency anemia (IDA) is a common condition in patients with inflammatory bowel disease (IBD) and ferric carboxymaltose (FCM) has shown fast correction of hemoglobin (Hb) levels and good tolerability. We evaluated the response to FCM in IBD patients with IDA. The primary outcome was the assessment of the rate of response to single or multiple FCM infusions after 12 months from the first infusion. Secondary outcomes were the response to a single FCM infusion after 3 months and the assessment of FCM safety. Methods We retrospectively included 185 consecutive patients from IBD Unit of “Villa Sofia-V. Cervello” Hospital who received at least a dose of 500 mg FCM infus…

Human herpes virus 8 interleukin-6 homologue triggers gp130 on neuronal and hematopoietic cells

2000

Human herpes virus-8 (HHV8) encodes a cytokine named viral interleukin-6 (vIL-6) that shares 25% amino-acid identity with its human homologue. Human IL-6 is known to be a growth and differentiation factor of lymphatic cells and plays a potential role in the pathophysiology of various lymphoproliferative diseases. vIL-6 is expressed in HHV8-associated-diseases including Kaposi's sarcoma, Body-cavity-based-lymphoma and Castleman's disease, suggesting a pathogenetic involvement in the malignant growth of B-cell associated diseases and other malignant tumours. We expressed vIL-6 in Escherichia coli as a fusion protein with recombinant periplasmic maltose binding protein. After cleavage from the…
