The consumption of a bread enriched with dietary fibre and l-carnitine improves glucose homoeostasis and insulin sensitivity in patients with metabol…

2015

The aim of this study was to evaluate the efficacy of a bakery product enriched with dietary fibre and L-carnitine in countering glucose homoeostasis and insulin sensitivity in patients with and without MetS. This was a 12-week, double-blind, randomized placebo-controlled trial employing fifty-four subjects (28 with MetS and 26 without MetS). After one month (run-in period), subjects were divided into two intervention groups: one received dietary fibre (5.59 g of soluble fibre and 9.49 g of insoluble fibre) plus 2325 mg of L-carnitine enriched bread (n = 26) and the other received placebo bread (n = 28). Anthropometric measurements, biochemical parameters inflammatory markers and LDL subfra…

Effect of weight loss on C3 and C4 components of complement in obese patients

2011

Eur J Clin Invest 2012; 42 (5): 503–509 Abstract Background  Circulating C3 levels are elevated in obese patients, but how this factor is affected after weight loss through diet is a question that is yet unanswered. Therefore, the aim of this study was to evaluate the effects of weight loss on lipid and hydrocarbonated metabolism parameters and on the levels of C3 and C4 components of complement in obese patients. Design  This is a longitudinal intervention study based on a 6-week very low-calorie diet (VLCD), a liquid formula of 603 kcal/day. A total of 131 middle-aged patients were distributed among grades II, III and IV of obesity. Anthropometric parameters, total cholesterol, triglyceri…

Differential regulation of hexameric and dodecameric hemocyanin from A. leptodactylus

2013

The oxygen binding properties of hemocyanins are regulated on a short time scale by effectors such as l-lactate, urate and protons, and on longer time scales by expression of the different types of subunits. For Astacus leptodactylus it was shown previously that acclimation to higher temperatures leads to increased levels of a 6-meric hemocyanin species, whereas at lower temperatures the 12-meric form prevails. Here we show that the temperature dependence of the two forms supports the idea, that the maintenance of high affinity towards oxygen is the driving force for the differential expression of these hemocyanins. Furthermore, the two different types of hemocyanin differ not only in the a…

Trasmissione del calore nei letti fluidizzati con liquidi

2007

Lo studio dei fenomeni relativi all’idrodinamica ed allo scambio termico nei letti fluidizzati è di grande interesse nell’Energetica industriale. Infatti è necessaria la loro comprensione per proporre modelli affidabili ai fini della progettazione e della simulazione del funzionamento delle tante apparecchiature nelle quali essi si manifestano. In molti processi industriali i contatti e le interazioni tra fluidi, siano essi liquidi o gas, e particolati solidi consentono una grande varietà di utili applicazioni. Si tratta del campo dell’ingegneria della fluidizzazione, che ha suscitato un ampio interesse fin dalla realizzazione, durante la Seconda Guerra Mondiale, dei reattori a letto fluido…

Analytical models for the pulse shape of a superconductor-ferromagnet tunnel junction thermoelectric microcalorimeter

2022

AbstractThe superconductor-ferromagnet thermoelectric detector (SFTED) is a novel ultrasensitive radiation detector based on the giant thermoelectric effect in superconductor-ferromagnet tunnel junctions. We demonstrate analytical models and solutions in the time domain for a SFTED operated as a microcalorimeter (pulse excitation), in the linear small-signal limit. Based on these solutions, the signal current and temperature pulse response were studied for two different electrical circuit models, providing design conditions for stable and non-oscillatory response.Kindly check and confirm whether the corresponding author is correctly identified.The corresponding author is correct.

Influence of torrefaction pretreatment on the pyrolysis of Eucalyptus clone: A study on kinetics, reaction mechanism and heat flow

2016

Abstract The adverse nature of biomass requires specific pretreatment processes to better utilize it in bioenergy applications, and torrefaction is one of the most recognized thermal pretreatment methods. In this regard, we studied the effect of torrefaction pretreatment on kinetics, reaction mechanism and heat flow during the pyrolysis of biomass by making a comparative analysis between the pyrolysis of dried and torrefied Eucalyptus wood. Torrefied biomass was produced at three temperatures, namely 250, 275 and 300 °C. Pyrolysis was performed at 700 °C. The char yield during pyrolysis increased from 22.39 percent to 36.34 percent when the torrefaction temperature was increased from 250 to…
