Interpersonal Emotion Dynamics in Couples With Somatic Symptom Disorder: Dyadic Coherence in Facial Temperature During Emotional Interactions
2021
OBJECTIVE: Disturbances in emotional processes are commonly reported in patients with a somatic symptom disorder (SSD). Although emotions usually occur in social interactions, little is known about interpersonal emotion dynamics of SSD patients during their actual emotional encounters. This study examined physiological coherence (linkage) between SSD patients and their partners, and in healthy couples during their emotional interactions. Secondarily, we explored group-level relationships between participants' and their partners' subjective affect. METHODS: Twenty-nine romantic couples (16 healthy and 13 SSD patient-couples) underwent a dyadic conversation task with neutral and anger-eliciti…
Evaluación de las células de la blastema de aleta caudal como donantes en quimeras intraespecíficas de pez cebra
2008
The blastema is a regenerative tissue with remarkable pluripotency. The aim of this work done on zebrafish (Danio rerio) was to define technical procedures required for obtaining and integrating blastema cells into embryos at the mid blastula transition stage (MBT) and the effect on survival, as well as the capacity to produce pigmented chimaeras. Wild type blastema cells were injected into gold type MBT embryos (E). Wild MBT blastomere cells were also injected into gold type MBT embryos as a control (C1). A second control group, C2, was not subjected to any manipulation. Survival was evaluated at 24, 48 and 72 h after performing the chimaerism, and the rate of adult chimaeras evaluated. Th…
Emotion awareness, mood and personality as predictors of somatic complaints in children and adults
2016
Background: The relationships among somatic complaints, emotion awareness and mood have been observed in late childhood and adolescence, but very few studies have been carried out in adult populations like this work. This study also incorporates personality dimensions that can exacerbate or reduce the emergence of somatic complaints. Therefore, the aim of this study is to analyse the combined contribution of emotion awareness, mood, and personality to healthy children and adults’ somatic complaints. Method: Self-reported questionnaires about emotion awareness, mood, personality, and somatic complaints were administered to 1,476 children (7-14 years old) and 479 adults (27-56 years old). Res…
Age-associated telomere shortening in mouse oocytes
2013
Abstract Background Oocytes may undergo two types of aging. The first is induced by exposure to an aged ovarian microenvironment before being ovulated, known as ‘reproductive or maternal aging’, and the second by either a prolonged stay in the oviduct before fertilization or in vitro aging prior to insemination, known as ‘postovulatory aging’. However, the molecular mechanisms underlying these aging processes remain to be elucidated. As telomere shortening in cultured somatic cells triggers replicative senescence, telomere shortening in oocytes during reproductive and postovulatory aging may predict developmental competence. This study aimed to ascertain the mechanisms underlying altered te…
In vitro anther culture of several cultivars of Citrus sinensis and Citrus clementina.

Citrus biotechnology
2020
Agricultural crops that can better withstand the changing climatic and pathogen landscape have been produced through natural selection throughout the millennia and, in recent years, through the process of human-assisted plant breeding and selection. However, a lack of genetic diversity in many commercially cultivated crops (due to monoculture) has made them more vulnerable to biotic and abiotic stresses (Esquinas-Alcazar, 2005; Keneni et al., 2012). Citrus, belonging to the Rutaceae family, is one of the most important commercial woody fruit crops in the tropical and subtropical areas of the world. The origin of citrus is traced back to parts of tropical and subtropical Southeast Asia (Wu e…
STUDY ON GAMETIC EMBRYOGENESIS VIA IN VITRO ANTHER AND ISOLATED MICROSPORE CULTURE IN FRUIT CROPS
2014
Fruit breeding is mainly based on both conventional (hybridization, mutation and selection) or biotechnological methods (somatic hybridization, genetic transformation and haploid production). The genetic improvement through the conventional methods is limited by many factors such as fruit trees long juvenile period, high heterozygosity, large size and sexual incompatibility. Haploids and doubled haploids, obtained through gametic embryogenesis have a potential use in fruit crops genetic improvement. The change of the microspores fate from the normal gametopytic pathway towards the sporophytic induction is affected by numerous factors. Genotype, medium composition and stress were considered …
Cellule somatiche in latte ovino: analisi e applicazione delle curve ROC
2013
Negli ovini da latte le mastiti costituiscono una delle principali cause di perdite economiche per la ridotta produzione e soprattutto per la scarsa qualità tecnologica del latte. Diversi studi hanno dimostrato che il contenuto in cellule somatiche (SCC) del latte può essere impiegato sia come metodo diagnostico sia come criterio di selezione nei programmi di miglioramento genetico per la resistenza alle mastiti. Obiettivo di questo lavoro è stato applicare la metodologia delle Receiver Operating Characteristics curves (ROC) per valutare la capacità diagnostica del SCC nel discriminare le mammelle infette da quelle sane e per individuare un valore soglia discriminante in ovini da latte. In …
Weighted Single-Step Genome-Wide Association Study Uncovers Known and Novel Candidate Genomic Regions for Milk Production Traits and Somatic Cell Sco…
2022
The objective of this study was to uncover genomic regions explaining a substantial proportion of the genetic variance in milk production traits and somatic cell score in a Valle del Belice dairy sheep. Weighted single-step genome-wide association studies (WssGWAS) were conducted for milk yield (MY), fat yield (FY), fat percentage (FAT%), protein yield (PY), protein percentage (PROT%), and somatic cell score (SCS). In addition, our aim was also to identify candidate genes within genomic regions that explained the highest proportions of genetic variance. Overall, the full pedigree consists of 5534 animals, of which 1813 ewes had milk data (15,008 records), and 481 ewes were genotyped with a …
Cellule somatiche ed isolamento di agenti mastidogeni in ovini di razza Valle del Belice
2013
Il conteggio delle cellule somatiche nel latte ovino si è dimostrato un valido strumento per la determinazione dello stato sanitario della mammella. Oggetto del presente studio è stato valutare eventuali relazioni fra il contenuto in cellule somatiche (SCC) e le infezioni mammarie (IMI) negli ovini. L’indagine è stata condotta nel periodo 2006-2012 su n.14072 campioni di latte individuale. In base al tenore i campioni sono state inseriti in 4 classi: 300.000; da 301.000 a 500.000; da 501.000 a 1.000.000 e ≥1.001.000 cellule/ml. Per l’isolamento colturale sono stati seminati 10 μl di latte su piastre di Agar Sangue incubate per 24-48 h a 37 °C in aerofilia e, se necessario, in microaerof…
