La alineación verbal del intérprete en un corpus de entrevistas médica español-italiano
This paper investigates how interpreters’ footing can change in the course of intercultural interactions in health-care settings. We have used a corpus (sample) collected in Barcelona, in a well-known clinic providing fertility treatments, over a period of four months, from April to July 2009. The theoretical framework is based on Goffman (1981: 325-326), Wadensjö (1998: 91-92) and Merlini y Favaron (2007: 116-117). Based on the analysis of real examples taken from the spoken interactions, the paper shows how the Spanish-Italian interpreters working at IVI Barcelona does not only translate what the primary interactants say, but, but they are active translators (Leanza, 2007), assuming different roles ranging from principal to responder to direct and indirect recapitulator, according to the communicative situation and to the interactants’ demands.El artÃculo analiza unos fragmentos de un corpus de diez entrevistas médicas, grabadas entre abril y julio de 2009 en el Instituto Valenciano de Infertilidad de Barcelona, caracterizadas por la presencia de un médico de habla española, uno o dos pacientes italianos y una intérprete. Se examina cómo cambia la alineación verbal de esta última, dependiendo de las diferentes situaciones comunicativas que tiene que afrontar. Para lograr este objetivo, se hace hincapié en los estudios de Goffman sobre el footing (o pie) (1981: 325-326), a los de Wadensjö (1998: 91-92) y de Merlini y Favaron (2007: 116-117). Se demuestra que la intérprete no sólo traduce lo que dicen los interlocutores primarios, sino que desarrolla un papel de traductora activa (Leanza, 2007), ya que habla con su propia voz para aclarar dudas o pedir a una de las partes que explique algo
Interazioni, ruoli e strategie di cortesia nell'interpretazione italiano-spagnolo in campo medico.
An Update on Applications of Cattle Mesenchymal Stromal Cells
Attention on mesenchymal stromal cells (MSCs) research has increased in the last decade
mainly due to the promising results about their plasticity, self-renewal, differentiation potential, immune
modulatory and anti-inflammatory properties that have made stem cell therapy more clinically
attractive. Furthermore, MSCs can be easily isolated and expanded to be used for autologous or
allogenic therapy following the administration of either freshly isolated or previously cryopreserved
cells. The scientific literature on the use of stromal cells in the treatment of several animal health
conditions is currently available. Although MSCs are not as widely used for clinical treatments
in cows as for companion and sport animals, they have the potential to be employed to improve
productivity in the cattle industry. This review provides an update on state-of-the-art applications of
bovine MSCs to clinical treatments and reproductive biotechnologies
Impiego di cellule staminali in terapia veterinaria
Over the past few years, in veterinary medicine there has been an increased interest in understanding the biology of mesenchymal stem cells (MSCs). This interest comes from their potential clinical use especially in wound repair, tissue engineering and application in therapeutics fields, including regenerative surgery. MSCs can be isolated directly from bone marrow aspirates, adipose tissue, umbilical cord and various foetal tissues. In this study, mesenchymal stem cells were isolated from equine bone marrow, adipose tissue, cord blood, Wharton’s Jelly and, for the first time, amniotic fluid. All these cell lines underwent in vitro differentiation in chondrocytes, osteocytes and adipocytes. After molecular characterization, cells resulted positive for mesenchymal markers such as CD90, CD105, CD44 and negative for CD45, CD14, CD34 and CD73. Adipose tissue and bone marrow mesenchymal stem cells were successfully applied in the treatment of tendinitis in race horses. Furthermore, for the first time in the horse, skin wounds of septicemic foal, were treated applying amniotic stem cells. Finally, results never reported have been obtained in the present study, isolating mesenchymal stem cells from domestic cat foetal fluid and membranes. All cell lines underwent in vitro differentiation and expressed mesenchymal molecular markers
Evaluation of Some Physical, Haemathological and Clinical Chemistry Parameters in Healthy Newborn Italian Holstein Calves
Abstract: The aim of the present study was to investigate some physical,
haematological and clinical chemistry parameters in the newborn Italian
Holstein calf at birth and at 24 h of life, to evaluate changes during the
immediate post-partum period. Forty-six Italian Holstein Friesian calves
were included in this study. Heart rate, respiratory rate and body
temperature were recorded at birth and at 24 h of life. The time needed to
raise the head, acquire sternal recumbency, stand up were also recorded.
Blood samples were collected before first feeding and at 24 h of age and
CBC count, L-lactate, glucose and total protein concentrations were
evaluated. The head was raised immediately in 46/46 calves, suckling
reflex was acquired within 12±9 min, sternal position in 5±2 min and
newborn stood up in 38±30 min. Some of the physical data,
haematological and biochemical values showed statistical differences
between birth and 24 h of age. The results from this study provide some
information about physical and laboratory data of Italian Holstein
Friesian calves, at birth and at 24 h of life. Our results confirm that
several clinical and laboratory values in newborn calves differ from adult
reference intervals and from calves of different breeds
Equine Bone Marrow and Adipose Tissue Mesenchymal Stem Cells: Cytofluorimetric Characterization, In Vitro Differentiation, and Clinical Application
The aim of the present work was to isolate, cultivate, differentiate, and conduct cellular
characterization of mesenchymal stem cells (MSCs) derived from equine adipose tissue
(eAT) and bone marrow (eBM). Isolated and characterized cells were used in racehorses
suffering from a superficial flexor tendon injury. Equine adipose tissue collection was
performed at the base of the horse tail, whereas eBM was aspirated from iliac crest.
Mononuclear cell fraction was isolated and cultured. In vitro differentiation and molecular
characterization at P3 of culture were performed. No statistically significant differences in
the number of cell doublings were found among different culture passages (P > .05).
Doubling time was greater for eBM than eAT (3.2 1.5 vs. 1.3 0.7; P < .05). Positive von
Kossa and Alizarin Red staining confirmed osteogenesis. Alcian Blue and Oil Red O staining
illustrated chondrogenesis and adipogenesis, respectively. Isolated cells resulted positive
for CD90, CD44, and CD105, whereas negative for hematopoietic markers, CD14, CD45, and
CD34. Using isolated cells for injured tendon therapy, no adverse reactions were observed,
and all inoculated horses returned to race competitions. In vitro results revealed the
immunophenotypic characterization of isolated cells similar to that observed in human
MSCs from the same sources; furthermore, in the present study, their clinical use proves
the safety of eBM-derived and eAT-derived MSCs and a successful outcome for the treated
animals that returned to their previous level of sport activity
Effects of Two Different Cooling Devices for Testicles Transport on Stallion Epididymal Sperm Quality
This study evaluates the effects of two cooling devices and temperature for testicles storage on epididymal sperm quality after 24 hours; different levels of seminal plasma (0% and 10%) were evaluated on sperm after recovering. Testicles from six stallions were recovered immediately after castration (2) or at the slaughterhouse (4); of the same animal, one testicle was placed in Equitainer (+8\ub0C), the other in a styrofoam box with ice (+3\ub0C). After 24 hours, the temperature of parenchyma was measured, and testicles and epididymal were weighted. Sperm were flushed from the cauda epididymides with Kenney extender, total sperm number recorded and motility and viability evaluated immediately after flushing (T0) with or without 10% SP (G1 Eq 0%, G2 Eq 10%, G3 Ice 0%, G4 Ice 10%). Motility and viability were evaluated after 24 hours and 48 hours of storage at +4\ub0C. Temperature of the parenchyma was lower in testicles stored in ice compared to Equitainer (3.2 \ub1 0.6\ub0C and 8.6 \ub1 2.5\ub0C, respectively; P < .05). Motility and viability at T0 were similar (P > .05) in G1 and G3, whereas addition of SP after recovery significantly improved motility only in samples stored in Equitainer (G2). Viability was higher (P < .05) in G2 than in G4. At T24 and T48, no differences (P > .05) in sperm quality were found between storage methods or samples with or without SP. In conclusion, equine testicles can be safely stored either at lower (+3\ub0C) or higher (+8\ub0C) temperature than +5\ub0C. This can be useful, especially when testicles are shipped in a hot climate, where devices cannot guarantee optimal refrigeration conditions
Ultrastructural characteristics and immune profile of equine MSCs from fetal adnexa
Both in human and equine species, mesenchymal stem cells (MSCs) from amniotic membrane (AM) and Wharton\ue2\u80\u99s jelly (WJ), may be particularly useful for immediate use or in later stages of life, after cryopreservation in cell bank. The aim of this study was to compare equine AM- and WJ-MSCs in vitro features that may be relevant for their clinical employment. MSCs were more easily isolated from WJ, even if MSCs derived from AM exhibited more rapid proliferation (P< 0.05). Osteogenic and chondrogenic differentiation were more prominent in MSCs derived from WJ. This is also suggested by the lower adhesion of AM cells, demonstrated by the greater volume of spheroids after hanging drop culture (P< 0.05). Data obtained by PCR confirmed the immunosuppressive function of AM and WJ-MSCs and the presence of active genes specific for anti-inflammatory and angiogenic factors (IL-6, IL 8, IL-\uce\ub21). For the first time, by means of transmission electron microscopy (TEM), we ascertained that equine WJ-MSCs constitutively contain a very impressive number of large vesicular structures, scattered throughout the cytoplasm. Moreover, an abundant extracellular fibrillar matrix was located in the intercellular spaces among WJ-MSCs. Data recorded in this study reveal that MSCs from different fetal tissues have different characteristics that may drive their therapeutic use. These finding could be noteworthy for horses as well as for other mammalian species, including humans
Comparative characterization of human and equine Wharton’s jelly derived mesenchymal stem cells
Mesenchymal stem cells (MSCs) have the capability to differentiate into wide range of specialized cells of mesodermal origin such as osteocytes, chondrocytes, adipocytes, cardiomyocytes, muscle fibers. Due to these properties, MSCs are considered as a new emerging treatment option and therapeutic agent in regenerative medicine. Promising results have been obtained after application of MSCs for treating tendon and joint disease in the equine model, making it favorable for therapeutic application. While the horse is considered a highly suitable model for orthopedic diseases, knowledge is lacking regarding the level of analogy of equine MSCs and their human counterparts. Therefore, the aim of this study was to assess the properties of human and equine Wharton’s jelly derived MSCs in a direct comparison. Obtained MSCs, were characterized for their staminal markers, proliferation and adhesion potential, ultrastructural morphology and their ability in differentiate towards osteogenic, chondrogenic and adipogenic lineages. Results showed a similar pattern in the expression of staminal markers, while a light difference was observed in the proliferation and adhesion potential. Ultramorphological analysis showed nuclear and citoplasmatic features comparable in human and equine MSCs. Finally, both MSCs were able to differentiate towards osteogenic, chondrogenic and adipogenic lineages. In conclusion, although revealing some potentially relevant differences, the study demonstrates a high level of analogy between human and equine MSCs, providing a basis for translational research in the equine model
Macroscopic characteristics of the umbilical cord in Standardbred, Thoroughbred and Warmblood horses
The umbilical cord (UC), the connection between mother and fetus via the umbilical vessels, carries nutrients and oxygenated blood to the fetus through the umbilical vein and removes deoxygenated blood and waste products via the umbilical arteries. It is designed to protect blood flow to the fetus during pregnancy. In equine medicine, only a few studies have described the UC, and most of these involved Thoroughbreds. The present study describes and compares the macroscopic features of the equine umbilical cord in three different breeds and in relation to the foal's gender. In addition, a possible correlation between UC features and maternal and perinatal factors is investigated. One hundred and twenty four healthy mares with normal pregnancies were enrolled in the study and were divided into three groups according to their breed: 70 Standardbreds (STB), 38 Thoroughbreds (THB) and 16 Warmbloods (WAB). The following data were recorded: mare's age and parity, gestation length, placental weight, presence of fetal membrane alterations, UC length and number of coils in the amniotic and allantoic portions, and the Umbilical Coiling Index (UCI), which is the ratio between total coils and total UC length. The UCI has not been investigated previously in veterinary medicine. Furthermore, immediately after foaling, APGAR score, foal's weight and sex were recorded. All the STB and WAB were housed in Italy and the THB were housed in New Zealand. Mares\ue2\u80\u99 mean age was higher in WAB than in THB and STB; the latter had a significantly shorter gestation length. The foal's weight was positively correlated with placental weight in all breeds; and in STB, foal weight was positively related to parity and gestation length. Mean total UC length was comparable to previous reports in THB, STB and WAB. The lengths of the two UC portions were statistically different between STB and THB, where the amniotic portion was longer than the allantoic one. In each breed, total UC length was correlated with total number of coils (THB and STB = 5 \uc2\ub1 1; WAB = 6 \uc2\ub1 1), the UC amniotic length was positively correlated with the number of amniotic coils and the allantoic length was positively correlated with the number of allantoic coils. The UCI values were 0.09 in STB and THB and 0.1 in WAB. This study provides reference values for UCI that could be included in the gross placental evaluation if its clinical importance were demonstrated
