Abstract: Mif was immunolocalized at implantation sites on gestation days (gd) 7.5, 10.5, 13.5 and 17.5. Ectoplacental cones and fetal placentas dissected from the maternal tissues were used for Western blotting and qRT-PCR assays on the same gestation days.During the post-implantation period (gd7.5), trophoblast giant cells showed strong Mif reactivity. In later placentation phases (gds 10.5-17.5), Mif appeared to be concentrated in the junctional zone and trophoblast giant cells. Mif protein expression increased significantly from gd7.5 to 10.5 (p = 0.005) and from gd7.5 to 13.5 (p = 0.03), remaining at high concentration as gestation proceeded. Higher mRNA expression was found on gd10.5 and was significantly different from gd13.5 (p = 0.048) and 17.5 (p = 0.009).The up-regulation of Mif on gd10.5 coincides with the stage in which the placenta assumes its three-layered organization (giant cells, spongiotrophoblast and labyrinth zones), fetal blood circulation begins and population of uNK cells reaches high proportions at the maternal counter part of the placenta, suggesting that Mif may play a role in either the placentation or in the adaptation of the differentiated placenta to the uterus or still in gestational immunomodulatory responses. Moreover, it reinforces the possibility of specific activities for Mif at the maternal fetal interface.Macrophage migration inhibitory factor (MIF) is a widely-expressed pleiotropic cytokine, exhibiting a broad range of roles that include pro-inflammatory activities in innate and acquired immunity, glucocorticoid antagonism [1-5], cell proliferation and survival [6-8], cell migration [9,10], modulation of NK-associated immune responses [11], DNA damage response and proteasomal control of the cell cycle [12]. It is constitutively expressed by a wide variety of cells [2,13] and can be either continuously expressed and secreted or stored intracellularly [2].MIF has been particularly studied during an inflammatory response.

Abstract: objective: this study investigated the complementary feeding practices and the factors associated with the appropriate timing of complementary feeding in children under one year of age. methods: the parents or caregivers of 1,176 children who attended the national immunization campaign in s?o bernardo do campo, southeastern brazil, in 2003 were interviewed to determine what the child was fed in the 24 hours prior to the interview. the prevalence of complementary food intake was estimated by a logistic regression model adjusted for age; the medians of the introduction of foods by survival analysis; and the factors associated with timely complementary feeding by poisson regression with robust adjustment of variance and hierarchical variable selection. results: complementary foods were introduced early: in the fourth month of age, nearly one-third of the children were already consuming fruit juices and one-fourth were consuming soft foods, fruits or soups. they were less likely to eat the same food as the family at eight months of age (48%). the median age for fruit intake was 266 days (95%ci 256-275), for vegetable soup was 258 days (95%ci 250-264) and for family meals 292 days (95%ci 287-303). factors associated with the intake of solid foods before age six months were: healthcare system, maternal age, maternal employment and use of pacifiers. conclusion: the early consumption of solid foods, a potential risk for the child's health and for the development of chronic diseases in adulthood, evidences the need for programmatic actions to reverse this situation.

Abstract: OBJETIVO: avaliar de forma subjetiva e objetiva a voz de pacientes com paralisia unilateral de prega vocal nos momentos pré-tratamento e pós-tratamento. MéTODOS: trata-se de um estudo retrospectivo por meio de revis o de prontuário, que analisou as grava es de vozes de 12 indivíduos com diagnóstico otorrinolaringológico de paralisia unilateral de prega vocal. O material de voz colhido foi a emiss o sustentada da vogal /a/, seguida de fala encadeada. As vozes pré e pós-terapia foram analisadas por meio da escala GRBASI, análise espectrográfica e medida do tempo máximo de fona o (TMF). Os parametros para análise espectrográfica foram: forma do tra ado, grau de escurecimento dos harm nicos, continuidade do tra ado, presen a de ruídos, presen a de sub-harm nicos e harm nicos definidos. A medida do TMF da vogal /a/ representou a maior de três emiss es. Os dados obtidos foram submetidos a análise descritiva de tendência central e dispers o, e ao Teste Wilcoxon. RESULTADOS: na análise perceptivo-auditiva, o parametro que mais se modificou no momento pós- tratamento foi o de soprosidade (B) (p=0,003), seguido do grau da disfonia (G) (p=0,004) e astenia (A) (p=0,01), sendo que estes resultados foram estatisticamente significantes. Com rela o ao espectrograma, houve melhora do tra ado em 91% dos pacientes, e os parametros que mais se modificaram foram: aumento do número de harm nicos (32%) e diminui o do ruído (24%). A medida do TMF da vogal /a/ apresentou-se significantemente maior no momento pós-fonoterapia (p=0,003%). CONCLUS O: pacientes com paralisia de prega vocal que foram submetidos ao tratamento fonoaudiológico apresentaram melhora dos dados perceptivo-auditivos, espectrográfico e do TMF.
