An odor timer in milk? Synchrony in the odor of milk effluvium and neonatal chemosensation in the mouse.
2012
International audience; Mammalian newborns exhibit avid responsiveness to odor compounds emanating from conspecific milk. Milk is however developmentally heterogeneous in composition as a function of both evolved constraints and offspring demand. The present study aimed to verify whether milk odor attractivity for neonates is equally distributed along lactation in Mus musculus (Balb-c strain). Therefore, we exposed pups varying in age to milk samples collected from females in different lactational stages. The pups were assayed at postnatal days 2 (P2), 6 (P6) and 15 (P15) in a series of paired-choice tests opposing either murine milk and a blank (water), or two samples of milk collected in …
I Vaticana fragmenta a due secoli dalla riscoperta
2022
Two centuries have passed since the palimpsest that transmits a Roman legal work known as the Vaticana fragmenta was rediscovered by Angelo Mai in the Vatican Apostolic Library in Rome. This paper reviews the main issues relating to this work and suggests some reasons why a new edition of the text is desirable. 1820 hat Angelo Mai in der Vatikanischen Apostolischen Bibliothek in Rom ein Palimpsest wiederentdeckt, welches ein römisches Rechtswerk – die so genannte Vaticana Fragmenta – überliefert. 200 Jahre sind seitdem genau vergangen. Dieser Beitrag gibt einen Überblick über die wichtigsten Aspekte dieses Werks und zeigt Gründe auf, warum eine neue Ausgabe dieses Textes wünschenswert ist.
Counterdiabatic vortex pump in spinor Bose-Einstein condensates
2017
Topological phase imprinting is a well-established technique for deterministic vortex creation in spinor Bose-Einstein condensates of alkali metal atoms. It was recently shown that counter-diabatic quantum control may accelerate vortex creation in comparison to the standard adiabatic protocol and suppress the atom loss due to nonadiabatic transitions. Here we apply this technique, assisted by an optical plug, for vortex pumping to theoretically show that sequential phase imprinting up to 20 cycles generates a vortex with a very large winding number. Our method significantly increases the fidelity of the pump for rapid pumping compared to the case without the counter-diabatic control, leadin…
Changes in Body Composition in Anorexia Nervosa : Predictors of Recovery and Treatment Outcome
2015
The restoration of body composition (BC) parameters is considered to be one of the most important goals in the treatment of patients with anorexia nervosa (AN). However, little is known about differences between AN diagnostic subtypes [restricting (AN-R) and binge/purging (AN-BP)] and weekly changes in BC during refeeding treatment. Therefore, the main objectives of our study were twofold: 1) to assess the changes in BC throughout nutritional treatment in an AN sample and 2) to analyze predictors of BC changes during treatment, as well as predictors of treatment outcome. The whole sample comprised 261 participants [118 adult females with AN (70 AN-R vs. 48 AN-BP), and 143 healthy controls].…
Modelagem da cinética de secagem de discos de maçã e abobrinha impregnadas a vácuo com antocianinas
2019
ABSTRACT: The aim of this research was to study the drying kinetics of apple and zucchini slices enriched with anthocyanins and to evaluate the influence of drying temperature on the anthocyanin content of apple and zucchini snacks. Apple (Granny Smith) and zucchini (Cucurbita pepo) slices were enriched with anthocyanins by vacuum impregnation with blueberry juice. Then, slices were dehydrated at 40, 50 and 60 ºC with 1.0 m/s air flow. Dehydrated samples were referred to as anthocyanin enriched snacks. Diffusion coefficient values improved by increasing the drying temperature, within the 2.81×10-10 to 5.78×10-10 m2/s range for apple slices and 2.02×10-10 to 3.99×10-10 m2/s for zucchini slic…
Investigation on the influence of spray-drying technology on the quality of Sicilian Nero d’Avola wines
2018
The purpose of the present work was to find a correlation between microencapsulation technology applied to wines and the resulting quality of the wine itself in terms of volatile composition and phenolic profile. To this aim, samples of Nero d'Avola wines produced in Sicily (Italy) were investigated in order to: i) elucidate the aromatic composition by means of HSâSPME coupled with GCâMS; ii) assess the polyphenolic content by UHPLC mass spectrometry; iii) compare the results obtained from both the screenings with those relative to the same wines that had previously been subjected to spray-drying. The results showed a marked reductionThe results here obtained evidenced a marked reductio…
Evaluación de la digestión in vitro de compuestos bioactivos de arándanos
2018
Estudios in vivo e in vitro han demostrado que las antocianinas provenientes de los arándanos ejercen efectos biológicos beneficiosos sobre la salud de los consumidores. Existen métodos de análisis in vitro que permiten evaluar la estabilidad de las antocianinas en relación con la interacción de los distintos componentes de las matrices alimentarias, el pH, la temperatura, presencia de inhibidores o potenciadores de absorción y presencia de enzimas. El objetivo del trabajo fue poner a punto la metodología de digestión in vitro y evaluar la biodisponibilidad in vitro de antocianinas presentes en jugo de arándanos y un snack formulado con jugo de arándanos y manzana. Los resultados indican qu…
CHARACTERIZATION AND DEVELOPMENT OF DIFFERENT METHODS TO EXTEND THE SHELF LIFE OF FRESH-CUT FRUIT
2017
La frutta di IV gamma è un prodotto altamente deperibile, con una shelf-life molto corta (5-7 giorni) influenzata dalle numerose variabili che entrano in gioco accelerando la senescenza del prodotto. Il suo alto valore aggiunto può giustificare l’utilizzo di soluzioni di conservazione più o meno costose. I metodi attualmente esistenti sono numerosi, spaziano dal dipping in sostanze naturali o sintetiche, all’utilizzo di packaging attivi, all’impiego di atmosfere modificate, ecc. Queste metodiche di conservazione incidono in maniera diversa sui costi finali del prodotto ma soprattutto sulla conservazione dello stesso e sul mantenimento della sua qualità lungo tutto il periodo di shelf-life. …
In vitro Antifungal Activity of Biopolymeric Foam Activated with Carvacrol
2020
Background: Active packaging represents a defining strategy to improve food quality and safety of the packaged foods. This study aimed to evaluate the in vitro ability of commercial biopolymeric foams, namely Mater-Bi (MB), activated with 20% of carvacrol, to develop a completely biodegradable and compostable packaging to inhibit the growth of spoilage and pathogenic yeasts.
 Methods: MB foams, with and without carvacrol, were produced by melt mixing and the foaming process was performed in a laboratory press. The antifungal activity of foams containing carvacrol was tested applying the disk diffusion method. Statistical analysis was done using XLStat software version 7.5.2 for Excel.&…
