José Watanabe et Doris Moromisato : deux écrivains nikkei-péruviens
No full textDans ce travail nous nous proposons d’étudier la poésie de deux écrivains nikkei-péruviens : José Watanabe et Doris Moromisato. Nous voulons observer comment elle témoigne d’un processus de construction identitaire. Avant d’aborder notre corpus, nous dressons un panorama historique et sociologique de la présence japonaise et nikkei en Amérique latine, et spécialement au Pérou, à travers notamment un examen des artefacts culturels destinés à rendre hommage à la communauté nikkei péruvienne qui s’est constituée au début du XXe siècle avec l’arrivée de main d’œuvre paysanne japonaise. Membres de cette communauté, fils et fille d’immigrés, Watanabe et Moromisato ont dû se définir comme péruviens d’origine japonaise, et l’ont fait pour une grande part en écrivant. Nous voulons montrer comment chacun exploite et intègre son héritage familial à son identité péruvienne. Nous traitons chaque auteur séparément dans le but de dégager plus clairement les points essentiels de leurs univers poétiques et de leur position face à leurs origines. Nous verrons ainsi que l’héritage culturel de Watanabe conditionne en parti sa posture de poète, et que sa vision du haïku japonais, tel que son père le lui a fait connaître enfant, révèle une conception particulière de son travail de poète. À l’inverse, les parents Okinawaïens peu instruits de Moromisato n’ont pu la mettre en contact avec la culture littéraire japonaise, et c’est une fois adulte qu’elle la rencontre telle qu’elle s’exporte. Issue d’un foyer renfermé sur les souvenirs d’un Okinawa rural, Moromisato envisage son identité multiple d’une façon différente que Watanabe, qui a grandi dans un foyer ouvert sur la culture autochtone.In this work we aim to study the poetry of two Peruvian nikkei writers: José Watanabe and Doris Moromisato. We hope to see how it reflects a process of identity building. Before going into the texts, we will provide a historical and sociological overview of the Japanese and Nikkei presence in Latin America, especially in Peru, through an examination of cultural artefacts paying tribute to the Peruvian Nikkei community formed at the beginning of the 20th century with the arrival of Japanese peasant workers. As members of this community (both are children of immigrants), Watanabe and Moromisato had to define themselves as Peruvians of Japanese origin, and did so largely by writing. We intend to demonstrate how each utilizes their family heritage to their advantage, integrating it into their Peruvian identity. We will study each author separately in order to clarify the essential characteristics of their poetic universes and their position in relation to their origins. We will see that Watanabe’s cultural heritage partially conditioned his work as a poet, and that his vision of the Japanese haiku, as passed down by his father, reveals unique insight into his artistic work. Conversely, Moromisato's undereducated Okinawan parents were unable to bring her into contact with Japanese literary culture, and it wasn’t until she was an adult that she encountered it in its exported form. Moromisato, who was born into a home closed off from influences outside those originating in /who was born into a home that thrived on memories of rural Okinawa, sees his multiple identities differently than Watanabe, who grew up in an environment that was open to peruvian culture
Effect of training and growth hormone suppression on insulin-like growth factor I mRNA in young rats
No full textEffect of training and growth hormone suppression on insulin-like growth factor I mRNA in young rats
No full text The growth hormone (GH)-insulin-like growth factor I (IGF-I) axis plays a role in the adaptation to exercise training, but IGF-I gene expression in response to exercise training and GH suppression has not been studied. Twenty female rates underwent a 4-wk treadmill training program begun in the prepubertal period (day 14 of life). In 10 of the training rats, GH production was suppressed by anti-GH-releasing hormone antibodies (GH suppressed). IGF-I mRNA and protein levels were measured in liver and hindlimb skeletal muscle. GH suppression reduced IGF-I mRNA expression in the liver to a much greater extent than in the muscle. In the GH control rats, training induced significant increases in hepatic exon 1-derived IGF-I mRNA (mean increase 30%; P < 0.05) and muscle exon 2-derived mRNA (mean increase 35%; P < 0.05). In the GH-suppressed rats, only muscle exon 1-derived transcripts were significantly increased by training (55%; P < 0.05) and this was associated with a significant increase in muscle IGF-I protein levels (P < 0.05). We speculate that the anabolic response to training may involve both GH-dependent increases in IGF-I mRNA in the liver and GH-independent increases in the muscle. </jats:p
Nutritional intervention during gestation alters growth, body composition and gene expression patterns in skeletal muscle of pig offspring
No full textpeer-reviewedVariations in maternal nutrition during gestation can influence foetal growth, foetal development and permanently ‘programme’
offspring for postnatal life. The objective of this study was to analyse the effect of increased maternal nutrition during different
gestation time windows on offspring growth, carcass quality, meat quality and gene expression in skeletal muscle. A total of 64
sows were assigned to the following feeding treatments: a standard control diet at a feed allocation of 2.3 kg/day throughout
gestation, increased feed allowance of 4.6 kg/day from 25 to 50 days of gestation (dg), from 50 to 80 dg and from 25 to 80 dg.
At weaning, Light, Medium and Heavy pigs of the same gender, within litter, were selected based on birth weight, individually
penned and monitored until slaughter at 130 days post weaning. Carcass and meat quality traits of the semimembranosus (SM) muscle were recorded post mortem. A cross section of the semitendinosus (ST) muscle encompassing the deep and superficial
regions were harvested from pigs (n518 per treatment) for RNA extraction and quantification of gene expression by real-time PCR. The results showed that doubling the feed intake from 25 to 50 dg reduced offspring growth, carcass weight, intramuscular fat content and increased drip loss of the SM muscle. Interestingly, protein phosphatase 3 catalytic subunit – a-isoform, which codes for the transcription factor calcineurin, was upregulated in the ST muscle of offspring whose mothers received increased feed allowance from 25 to 50 dg. This may provide an explanation for the previous observed increases in Type IIa muscle fibres of these offspring. Increasing the maternal feed intake from 50 to 80 dg negatively impacted pig growth and carcass weight, but produced leaner male pigs. Extending the increased maternal feed intake from 25 to 80 dg had no effect on offspring over the standard control gestation diet. Although intra-litter variation in pig weight is a problem for pig producers, increased maternal feeding offered no improvement throughout life to the lighter birth weight littermates in our study. Indeed, increased maternal nutrition at the three-gestation time windows selected provided no major benefits to the offspring.Teagasc, under the National Development Plan;

No full textThe development of totally transparent position sensors
No full textWe describe an improved version of COPS, a CCD based Optical Position Sensor, which can measure or monitor positions of attached elements with accuracies better than 0.05 mm at distances of tens of meters. The main application of this device is in the precision alignment and monitoring of radiation detectors in experimental high-energy physics. The improved sensor, named NUCOPS, has a set of four linear CCD arrays attached to the inside walls of a rigid square tube, and can be illuminated by a cross-hair laser coming from either direction. Like the old device, a NUCOPS can measure changes in its position to the laser lines with reproducibility better than 2 mum. It has been designed specifically for use in the alignment system of the Endcap Muon detectors for the CMS experiment at LHC
Expression of a monoclonal antibody (3G5) defined ganglioside antigen in the renal cortex
No full textExpression of a monoclonal antibody (3G5) defined ganglioside antigen in the renal cortex. The monoclonal antibody (mAb) 3G5 was found, by indirect immunofluorescence, to bind to renal cortical structures in frozen sections of human, rat and calf kidneys. Double indirect immunofluorescence studies on frozen sections of rat kidneys showed that 3G5 stained only the glomerulus and the distribution of the 3G5 antigen on the glomerulus was more extensive than the staining observed with antibodies to Factor VIII antigen. 3G5 stained the proximal convoluted tubules and collecting tubules in bovine renal sections but glomeruli did not stain with 3G5. The 3G5 mAb did not stain tissue cultured bovine glomerular endothelial cells or mesangial cells, but did stain bovine glomerular epithelial cell cultures. 3G5 did not stain MDCK cell cultures. The binding of mAb 3G5 to glomeruli was investigated by immunoelectron microscopy of rat renal tissue. In contrast to the podocyte specificity on bovine glomerular cells in vitro, it was found that the specificity of 3G5 expression on rat glomerular cells in vivo was broader. No binding of mAb 3G5 was found outside the glomerulus in the rat renal cortex. Podocytes, endothelial cells and capsular epithelial cells expressed the 3G5 antigen most strongly. A lesser amount of binding was found in the glomerular basement membrane. The mesangium showed a little binding of mAb 3G5 and no binding at all was found to other cortical structures. The 3G5 antigen in rat renal tissue was found to be a glycolipid that migrated between the ganglioside markers GM2 and GM1 by immunostaining of thin layer chromatograms. The 3G5 mAb has previously been shown to react with microvascular pericytes, resting T-lymphocytes and cells of the brain, thyroid gland and adrenal gland as well as various malignancies. The significance of the tissue specific patterns of expression remains unclear and will be understood only when the function of this ganglioside is elucidated

D. 1998;58(11): 112002.We present a next-to-leading order QCD analysis of the presently available data on the spin structure function g(1) including the final data from the Spin Muon Collaboration. We present results for the first moments of the proton, deuteron, and neutron structure functions, and determine singlet and nonsinglet parton distributions in two factorization schemes. We also test the Bjorken sum rule and find agreement with the theoretical prediction at the level of 10%. [S0556-2821(98)07117-3]
