Seasonal variations of antimicrobial activity and chemical composition of essential oils extracted from three Citrus limon L. Burm. cultivars

2014

In order to investigate the seasonal variations of antimicrobial properties and chemical composition of essential oils (EOs), three different cultivars of Citrus limon L. Burm. spp. (Femminello Santa Teresa, Monachello and Femminello Continella) were collected at 6-week intervals, from December 2012 to April 2013, for a total of four harvests. The EOs were extracted from lemon peel by hydro-distillation. The antimicrobial activity, tested by paper disc diffusion method, was evaluated against common food-related pathogenic bacteria (Listeria monocytogenes, Staphylococcus aureus, Salmonella enterica and Enterobacter spp.). EOs were more effective against Gram-positive than Gram-negative bacte…

Antilisterial effect of citrus essential oils and their performance inedible film formulations

2016

[EN] The antimicrobial activity of eight essential oils (EOs) extracted from the fruit peel of Citrus genotypes (orange, mandarin and lemon) was evaluated against 76 strains of Listeria monocytogenes, previously isolated from different food matrices. EOs showing the most (EO L2 and EO L8) and least (EO O3 and EO M7) effective inhibition activities were chemically characterized by gas chromatography coupled with mass spectrometry (GC/MS) to compare their composition. EO L2 and EO L8 were chosen to determine the MIC and to evaluate the cell viability of the most sensitive strains (L. monocytogenes LM35 and LM69) after 1, 2, 4 and 6 h of exposure. The effectiveness of chitosan (CH) and methylc…

Constancy and evolution of an engaged writing : the work of Carmen de Burgos, journalist, essayist and novelist

2016

Carmen de Burgos died in 1932, leaving behind a considerable amount of written material: thousands of articles published in different newspapers, essays, novels and hundreds of “novelas cortas”. The works and the memory of this women’s rights activist were doomed to oblivion during Franco’s dictatorship. This thesis aims to rediscover and analyse these works from its various perspectives. We have been looking for the constant trends but also the evolutions. Carmen de Burgos has indeed evolved in her conception of the woman’s role and of the rights she had to acquire. In the early stages of her fight, she had been mainly focusing on the acquisition of equalitarian legal and social rights. Sh…

How functional coupling between the auditory cortex and the amygdala induces musical emotion: a single case study.

2013

Music is a sound structure of remarkable acoustical and temporal complexity. Although it cannot denote specific meaning, it is one of the most potent and universal stimuli for inducing mood. How the auditory and limbic systems interact, and whether this interaction is lateralized when feeling emotions related to music, remains unclear. We studied the functional correlation between the auditory cortex (AC) and amygdala (AMY) through intracerebral recordings from both hemispheres in a single patient while she listened attentively to musical excerpts, which we compared to passive listening of a sequence of pure tones. While the left primary and secondary auditory cortices (PAC and SAC) showed …

Behavior of four main dairy pathogenic bacteria during manufacturing and ripening of pecorino siciliano cheese

2020

Background: Consumption of raw cheese may be associated with different diseases. This study aimed to evaluate behavior of four pathogenic bacteria during manufacture and ripening of Protected Designation of Origin (PDO) Pecorino Siciliano cheese.
 Methods: The experimental cheese groups were inoculated with pathogenic bacteria, including Escherichia coli O157, Listeria monocytogenes, Salmonella Enteritidis, and Staphylococcus aureus. The cheese making processes were monitored from milk curdling until 3 months ripened cheeses and the levels of Lactic Acid Bacteria (LAB) and the four dairy pathogens were evaluated by plate counts. Randomly Amplified Polymorphic DNA (RAPD)-Polymerase Chai…

Listening understanding and acting (lung): focus on communicational issue in thoracic oncology.

2019

Background: In the field of oncological assistance, nowadays we have to deal with a complex scenario where patients got used to obtain a huge amount of information through internet or social media and to apply them in performing their health-related decisions. This landscape requires that clinicians become able to handle therapeutical approaches and adequate skills in communication tools to satisfy the current needs. Our project aimed to build a communication model based on clinical oncologists’ real experiences in order to find a simple way to share with patients all the innovative therapeutical opportunities today available in lung cancer. The final goal is to design a flexible and person…

Hand Gestures Alert Auditory Cortices

2017

When acquiring a foreign language, the first challenge is to break into the speech stream to identify basic linguistic units. The present study tested the hypothesis that hand gestures facilitate this process by alerting auditory cortices to attend to and identify meaningful phonemic information. During fMRI data acquisition, participants watched videos of an actor speaking in Russian under three conditions. Sentences were produced with just speech alone or were accompanied by two types of hand gestures: 1) metaphoric gesture and 2) free gesture. The main finding was that there was increased auditory cortex activation when both types of gestures accompanied speech compared to speech alone, …

Audiovisual Representation in Spanish and European Election Debates

2020

The presence of ever more conflicting stances between Europhiles and Eurosceptics has revealed some audiovisual discourses unknown until now. The fragmentation of inconclusive narrative discourse and staged situations with a clear intent to clash all make it necessary to analyse in detail the role given by the audiovisual media to the European process of democratisation. This study addresses the audiovisual discourse in Spanish public television (TVE) with the intention of discovering how the different topics addressed in debates are dealt with in audiovisual production, and whether those topics have benefited from certain decisions by the production team that are subjective a priori. Using…

Oppilaiden kaikupuheen tehtävät kielellisesti epäsymmetrisissä luokkahuonekeskusteluissa

2017

Repeating the words of the conversational partners gives the persons with restricted communicative abilities a possibility for taking an active part in and exerting some control in the conversational interaction. Earlier research has approached the repeats with two different viewpoints: they have been considered either as problematic and meaningless echolalia, or as motivated communication meaningful for speakers themselves. This paper examines the functions for which students with special needs use repetition in their interaction with teachers and the ways in which teachers treat these echolalic responses in classroom talk. The research data consists of the video-recordings of lessons in o…
