Tjioe, Kellen Cristine. "Expressão da podoplanina em ameloblastomas e folículos pericoronários de dentes não-irrompidos: estudo comparativo com a expressão do Ki-67." Universidade de São Paulo, 2011. http://www.teses.usp.br/teses/disponiveis/25/25149/tde-16082011-105201/.
Full textThe association between podoplanin and cellular proliferative activity has been demonstrated but is still source of debate. The aim of this study was to investigate the expression of podoplanin in ameloblastomas and remnants of odontogenic epithelium (ROE) from dental follicles of unerupted teeth and verify the relation between the podoplanin expression and proliferative activity of the odontogenic cells. Thirty-three patients submitted to the incisional biopsy or resection of ameloblastoma and 32 patients submitted to the extraction of unerupted tooth were selected for analysis. Archived paraffin-embedded ameloblastomas and dental follicles specimens were sectioned and stained with anti-human podoplanin and anti-Ki-67 antibodies. The podoplanin expression by odontogenic epithelial cells was evaluated using a score method and the Ki-67 labelling index was obtained by the percentage of positive odontogenic cells (at least 500 cells/ameloblastoma and all ROE cells). All ameloblastomas showed podoplanin expression in ameloblast-like cells of the epithelial islands. Weak or absent immunostaining was observed in the central cells resembling stellate reticulum. Podoplanin expression in ROE was mainly found in the cells in contact with the connective tissue. Membranous expression of podoplanin in ameloblastomas was stronger than its expression in ROE (!=0.001). Statistically significant difference between cytoplasmic and membranous expression of podoplanin in ROE was observed (!=0.001). The index of cellular odontogenic proliferative activity, verified by Ki-67 expression, was highest in ameloblastomas when compared with ROES (!<0.001). No statistically significant correlation between podoplanin and cellular odontogenic proliferative activity in ameloblastomas and dental follicles was found (!>0.05). These results support the evidence that there is no connection between podoplanin expression and odontogenic cellular proliferative activity in ameloblastomas and reinforce that the exact role of this protein in benign odontogenic tumor needs to be elucidated.

Full textThe yolk sac is one of the extra-embryonic membranes which plays an important role in early embryonic survival and serves as source of nutrition during the period where in the placenta is not completely true formed. The yolk sac is a likely source of stem cells, which have first blood cells during development in mammals, the red blood cells, which express transcription factors that specify these hematopoietic cells to their destination. This study aimed to identify and characterize hematopoietic stem cells from the yolk sac of bovine embryos at different stages of pregnancy, which are collected at a local slaughterhouse. For a description of the macroscopic and cellular culture of yolk sac cells, are as follows bovine embryos were divided into groups of gestational age: Group I (25 to 29 days), Group II (30 to 34 days), Group III (35 to 39 days ), Group IV (40 to 44 days) and Group V (45 to 50 days) which stayed longer in culture and showed the formation of cell clusters, different from groups IV and V (40-45 days) in few that remained days in culture and showed no cell clumps. This divergence is related to gestational age (45 to 50 days), during which begins regression of the yolk sac. In flow cytometry groups I, II and III (25 to 39 days) had similar characteristics, high expression of hematopoietic markers (CD34, CD90 and CD117). For the groups IV and V (40 to 50 days) it is observed a decrease in expression of CD117 and CD34 (hematopoietic markers) and in group V were increased expression of CD45 (leukocyte marker), confirming that these cells are not keeping Undifferentiated cells are shown to be resistant to cryopreservation, capable of forming colonies in methylcellulose matrix showed the formation of colonies after 14 days in culture morphology and to blood cells (lymphocytes and monocytes) was confirmed by cytology cell. In gene expression was low GATA3 gene expression, different levels of expression between the groups for the marker and RUNX1 ANXA5. Our most significant findings confirmed the isolation and identification of hematopoietic cells from the bovine embryo yolk sac, therefore, it is feasible and an effective way of obtaining stem cells for future applications in cell therapy and gene.

Full textThe main goal of this study was to describe morphology and the early gestational development of 15 to 70 day-old bovine embryos obtained by natural mating and 35 day-old bovine embryos obtained by in vitro fertilization (IFV) technique. One hundred and forty-one concepts originated by natural mating and seven by IVF technique were used. All concepts were dissected, macroscopically measured and photographed. Extraembryonic membranes were cut in 5 cm2 fragments and fixed in 4% paraformoldehyde for light and Scanning Electron Microscopy (SEM) and in 2.5% glutaraldehyde for Transmition Electron Microscopy (TEM). Ali membranes showed different stages of development during analyzed periods. The beginning of allantois macroscopic vascularization, the attempt of fusion between allantois and chorium membranes and the effective development of the first cotyledons were observed in 30-to-40 day-old embryos with 1.9± 0.24 cm of Crown-Rump (CR) length. The average CR, the embryos and gestational sac weight, the chorion and amnion length increased during gestation. The allantoic epithelia showed a cellular dimorphism with 0.9 em CR, however, the maturation has not happened until the foetal length of 7.2 em CR. The trophoblast showed different levels of mononucleate cells and binucleate giant cells. The yolk sac persisted until 70 days of gestation and the epithelium seemed functionally activated until 50 days of gestation. The CR and yolk sac size were the only measured macroscopic parameter showingdifference between natural mating and FIV concepts. Yolk sac size presented average values of 5.53 cm and 1.07 cm for natural mating and FIV concepts, respectively. Therefore, it is necessary to analyze a higher number of FIV embryos to corroborate that observed yolk sac size difference. All results obtained in this study suggest the existent of an active vitelline placenta, important to the gestational maintenance and temporarily establish between the transitory choriovitelline placenta and the permanent chorioallantoic placenta.

Full textThe yolk sac is the main source of embryo nutrition during the period that true placenta are not still formed and responsible by hematopoieses because from it were developed the blood cells, as a part of embryo primitive circulatory system. We aimed to characterize the transitional area between the yolk sac and the primitive intestine by light microscopy, transmission electron microscopy and detection of germ cell lines by Oct-4 immunohistochemistry. Were done in all embryos serial sections to permit the identification for all structures. Were possible identify the yolk sac connection with primitive intestine composed by many blood islet corresponding to relation with yolk and mesenchymals cells. Inside the vessels were identified hemangioblasts. The layer corresponding to mesenchyme is thin and with elongated cells and the vitellinic membrane endoderm is composed by large, uni or binucleate endodermic cells. This shape is similar to a gland related to their architecture, vessels islets and tissue layers. Primitive intestine epithelium begins their differentiation with stratified columnar cells and undifferentiated mesenchymals cells. This transitional area is thin related to their lumen with irregular shape and constituted by delicate lumen basement and hemangioblast. Inside the mesenchyme there are many smaller capillaries observed with hemangioblast in it. Embryos and fetus submitted to immunohistochemistry and were verified positive cells like metanefrons, gonads, hepatic parenchyma and yolk sac.

INTRODUÇÃO: A correção endovascular do aneurisma de aorta abdominal (EVAR) modificou o tratamento desta patologia, reduzindo a mortalidade e as complicações, á curto prazo quando comparada à cirurgia aberta. Ainda assim, os pacientes necessitam de seguimento rigoroso a fim de reconhecer as possíveis complicações. O crescimento do diâmetro do saco aneurismático pós-EVAR está relacionado ao risco de rotura ou necessidade de reabordagem, sendo que alguns fatores pré-operatórios podem prever esse aumento. OBJETIVO:Identificar se os sintomas pré-tratamento EVAR podem ser um fator preditivo para a continuidade da expansão do saco aneurismático após tratamento, no seguimento em 12 meses. MATERIAL E MÉTODOS: Estudo retrospectivo realizado através da coleta de dados do prontuário dos pacientes em seguimento na Faculdade de Medicina de Botucatu e que preencheram critérios de inclusão. Os pacientes foram separados em dois grupos de estudos: G1- Pacientes assintomáticos quanto a presença do aneurisma de aorta infrarenal; G2- Pacientes sintomáticos quanto a presença do aneurisma de aorta infrarenal. Todos os grupos foram acompanhados por 12 meses e avaliados quanto ao crescimento do saco aneurismático após o procedimento endovascular, através de AngioTC e Duplex Scan e coleta do exame “proteína C Reativa” para avaliação inflamatória relacionada ao EVAR. RESULTADOS: Foram 9 estudados 112 pacientes. A faixa etária apresentou uma média de 68,6 anos. 80% eram do sexo masculino e 95% brancos. A maioria dos pacientes eram hipertensos e fumantes, 74,1% e 67% respectivamente. No total houve 22,3% de endoleak e o aumento do saco aneurismático foi de 26,8%. Avaliando todos os pacientes, ocorreu diminuição do diâmetro do AAA em média de 0,8cm, entre o pré e pós-operatório. Observou se que 25,3% dos assintomáticos e 30% dos sintomáticos tiveram crescimento do saco aneurismáticos. A presença de endoleak ocorreu em 19% dos assintomáticos e 41,2% dos sintomáticos. No total, 40 % dos pacientes que evoluíram com aumento do saco aneurismático apresentavam endoleak. CONCLUSÃO: Os pacientes que tiveram dor no pré-operatório, portanto, sintomáticos, apresentaram uma taxa numérica maior do crescimento do saco aneurismático em relação ao grupo que não apresentava sintomas, mas este achado não foi estatisticamente significante. A presença do endoleak não foi a única causa do crescimento dos AAAs. Não houve diferença do PCR colhido no pré-operatório em relação ao crescimento do AAA em ambos os grupos. A hipertensão arterial foi a comorbidades mais frequente na nossa casuística.
BACKGROUND: The endovascular repair of abdominal aortic aneurysm (EVAR) modified its treatment, reducing the mortality and complications in short-term compared to open repair. Even though, patients need strict follow-up to identify possibly complications. The sac aneurysm enlargement after EVAR is related to the risk of rupture or reintervention, with some preoperative factors can predict this enlargement. OBJECTIVE: Identify if the AAA symptons, especially pain, are predictors of abdominal aortic aneurym sac enlargement after EVAR. METHODS: Retrospective study through the gathering of data about the patientes in follow-up in Botucatu School Medicine. The patients were separated in two groups: G1 – assymptomatics in the preoperative; G2 – syptomatic in the preoperative. Both groups were followed-up for 12 months to the sac enlargement through AngioCT, duplex scan and Reative-C-Protein. RESULTS: 112 patientes were analysed. The age average was 68,6 years. 80% were male and 95% white. Most of them were hypertensive and smoker, 74,1% and 67% respectively. There was 22,3% of endoleaks and 26,8% sac enlargement ratio. 25,3% of the assymptomatics and 30% of the symptomatics had sac enlargement. 19% of the assymptomatics compared with 41,2% of the symptomatics had endoleak. 40% of the patients with sac enlargement had endoleaks. CONCLUSION: The symptomatics preoperative patients has a higher risk compared with assymptomatic group. The endoleak is not the only 11 reason for the AAA sac enlargement. There was no difference between the groups G1 and G2 related to AAA sac enlargement and Reative-CProtein. Hypertension was the most prevalent comorbidity in our study.

Full textMurine rodents are well investigated in regard to placentation, but data for other groups such as cricetids including New World mice or Sigmodontinae are sparse. Recently the placenta and fetal membranes are regarded to be promising sources for obtaining stem cells. In particular, the yolk sac is structurally diverse and shows important functions throughout gestation. For this reason, this study aims to describe the chorioallantoic and yolk sac placentation in Necromys lasiurus. In addition, the potential of the yolk sac as a source for mesenchymal stem cells that are not well studied so far will be evaluated. In total, 10 individuals from early gestation to near term were investigated by means of histology, immunohistochemistry and electron microscopy as well as cell culture and differentiation, flow citrometry and immunocytochemistry. The discoidal chorioallantoic placenta was organized in a labyrinth zone, junctional zone, and decidua. The labyrinth was most import for maternal-fetal exchange processes. It possessed a hemotrichorial barrier of about 2.41 µm thickness near term. The junctional zone included syncytial areas and cytotrophoblasts. Trophoblast giant cells were located between the junctional zone and decidua as well as in the lateral margins of the placenta. The morphology of the inverted visceral yolk sac varies according to its location and relationship with the placenta and uterus. When cultured, the adherent cells of the yolk sac formed fibroblastoid colonies (92.13%) and expressed mesenchymal stem cells markers, and some hematopoietic precursor cells markers. They showed successful osteogenic, adipogenic, and chondrogenic differentiation and did not develop tumors when transferred to nude mice. Thus, these cells resulted as stem cells with promising therapeutic values for cell therapy.

Full textThe yolk sac is an embryonic attachment present in all animal species, which function is to keep the primary development of the fetus until the placenta assumes this function. Moreover, it plays important roles as: nutrition of the embryo, protein synthesis, phagocytic activity, transfer of materials and hematopoiesis. The use of embryonic stem cells generates many discussions because of the ethical and religious issues associated with the obtaintion of these cells. Also the relationship of low plasticity of adult stem cells motivates researchers to explore other sources of stem cells. Thus, cells from tissues such as the embryonic anexes call more attention, due to its ease of access, rapid growth and good plasticity. Our group has shown that cells of the yolk sac has good ability to proliferate and are multipotent. Several researchers have shown that the period in which the cells are obtained can be critical for differentiation. Therefore, in this project we aimed to establish and characterize stem cells from dog yolk sac in two stages of pregnancy, in order to analyze comparatively the expression profile of mesenchymal, hematopoietic and plurypotency markers, and study their behavior and plasticity potencial in vitro. In this study we observed that yolk sac cells obtained from pregnancies at 40 and 50 days adhered to plastic, had fibroblast like-morphology, good cell proliferation and differentiated into adipocytes and osteocytes and expressed some mesenchymal markers, therefore suggesting to be a mesenchymal stem cell. Also, they did not lead to tumor formation when injected into immunosuppressed mice, nude.

Full textThe samples were obtained from adult mares, totalizing 42 animals, being 30 for the description and characterization of the placenta and embryonic annexes / fetus. The other 12 animals were used for the cell culture of amniotic membranes and yolk sac. The embryos were measured obtaining Crow-Rump and fixed for morphological description. The vitelline and amniotic fragments were cultured in α-MEM, supplemented with 20% fetal bovine serum, 1% nonessential amino acids, 1% glutamine and 1% antibiotic, incubated at 37 º C and 5% CO2. As for the material obtained, the chorion is the outer embryo membrane, consisting of morphologically columnar epithelium and mesenchyme richly vascularized and rich in collagen fibers. The allantois is well vascularized and developed, consisting of a simple squamous epithelium and with the presence of microvilli. The amnion is an avascular membrane consisting of a single thin layer of squamous cells, basal membrane and mesenchyme. The yolk sac exhibits a yellowish appearance with surface vessels, consisting of two cell layers interspersed with a vascularized mesenchyme. The chorionic girdle appears as a halo around the fetus at the point where the allantoid membranes and the yolk sack meet. Regarding embryos in general, the presence of the forebrain in formation, branchial arches, pigmented optic vesicle, open cranial neuropore exposing the so called 4th encephalic ventricle, and pronounced cervical flexure were noticed. The cardiac impression was observed and the fore and hindlimbs had a \"paddle\" shape. Fetuses in general had the nasal and oral cavities externally defined; presented the growth of the auricular pavilion and early growth of the external ear; and formation of the nail apparatus in fore and hindlimbs. The ribs become more prominent and some structures already presented ossification. Morphologically the yolk and amniotic cells was presented as fibroblastoid and epithelioid. The progenitor cells isolated from the yolk sac and the amnion, in the fifth passage, showed normal karyotype (2n = 64). The cells population in the yolk sac showed a progressive growth, not constant until the fifth passage, and a marked decline in P10. For the amniotic membrane, the cell population showed a constant growth, not linear, until the eighth passage, and a marked decline in P10. In immunocytochemistry, the yolk sac cells and amniotic membranes presented themselves as immunopositive for: Oct-4, Nanog, SSEA-3, vimentin, cytokeratin 18 (CK18) and PCNA. Either the yolk sack as the aminiotic membranes expressed the markers CD 45, CD 105, Oct3 / 4, Nanog, CD 34 and Stro-1. Both cell lines demonstrated the capacity to differentiate into adipocytes, osteocytes and chondrocytes and had no carcinogenic potential in NUDE mice.

La valoración de empresas es un proceso mediante el cual, a través de información contable, financiera y económica es posible obtener un valor determinado para una compañía. Lo anterior permite apoyar procesos de toma de decisiones respecto a inversiones, fusiones y adquisiciones, y enajenaciones de empresa, entre otros. Si bien existen diferentes métodos de valoración, en este estudio se utilizará el método de flujo de caja descontados y el método de múltiplos o comparables. El primero se enfoca en proyectar los resultados de la empresa bajo determinados supuestos, obteniendo un flujo de caja libre, el cual descontado a una tasa WACC, también determinada a través de este método, permite obtener una estimación del valor de la firma; lo anterior tiene como fundamento teórico lo expuesto por Modigliani y Miller. Por otro lado, el método de múltiplos o comparables, consiste en escoger value drivers de una empresa, los cuales se encuentran relacionados con el valor de esta y que permiten establecer una relación entre el valor de la variable y el valor de la firma, determinando de forma simple el valor aproximado de una firma, a través de la comparación entre múltiplos de empresas que participan en el mismo sector industrial. Sin embargo, su mayor simplicidad podría generar menor precisión en la estimación del valor de la compañía. En particular, el objetivo del presente estudio, es estimar el valor de la acción al 30 de Septiembre del 2017 del retailer chileno SACI Falabella, el cual cuenta con presencia en 6 países de Sudamérica. Lo anterior permite determinar si el valor de la acción se encuentra subvalorado o sobrevalorado por el mercado. Con lo anterior, se estimó el valor de la compañía y su precio por acción al cierre de sept- 17, obteniendo un precio de $6.209 bajo el método de flujo de caja descontado, el cual es consistente con el precio de la acción observado a la misma fecha ($6.242), con una diferencia menor al 1%. Adicionalmente, la valorización mediante múltiplos arrojo un precio de la acción al cierre de sept-17 de $3.887, el cual es un 38% inferior al precio real observado.

A correção endovascular do aneurisma de aorta abdominal (EVAR) modificou o tratamento desta patologia, reduzindo a mortalidade e as complicações, á curto prazo quando comparada à cirurgia aberta. Ainda assim, os pacientes necessitam de seguimento rigoroso a fim de reconhecer as possíveis complicações. O crescimento do diâmetro do saco aneurismático pós-EVAR está relacionado ao risco de rotura ou necessidade de reabordagem, sendo que alguns fatores pré-operatórios podem prever esse aumento. OBJETIVO:Identificar se os sintomas pré-tratamento EVAR podem ser um fator preditivo para a continuidade da expansão do saco aneurismático após tratamento, no seguimento em 12 meses. MATERIAL E MÉTODOS: Estudo retrospectivo realizado através da coleta de dados do prontuário dos pacientes em seguimento na Faculdade de Medicina de Botucatu e que preencheram critérios de inclusão. Os pacientes foram separados em dois grupos de estudos: G1- Pacientes assintomáticos quanto a presença do aneurisma de aorta infrarenal; G2- Pacientes sintomáticos quanto a presença do aneurisma de aorta infrarenal. Todos os grupos foram acompanhados por 12 meses e avaliados quanto ao crescimento do saco aneurismático após o procedimento endovascular, através de AngioTC e Duplex Scan e coleta do exame “proteína C Reativa” para avaliação inflamatória relacionada ao EVAR. RESULTADOS: Foram estudados 112 pacientes. A faixa etária apresentou uma média de 68,6 anos. 80% eram do sexo masculino e 95% brancos. A maioria dos pacientes eram hipertensos e fumantes, 74,1% e 67% respectivamente. No total houve 22,3% de endoleak e o aumento do saco aneurismático foi de 26,8%. Avaliando todos os pacientes, ocorreu diminuição do diâmetro do AAA em média de 0,8cm, entre o pré e pós-operatório. Observou se que 25,3% dos assintomáticos e 30% dos sintomáticos tiveram crescimento do saco aneurismáticos. A presença de endoleak ocorreu em 19% dos assintomáticos e 41,2% dos sintomáticos. No total, 40 % dos pacientes que evoluíram com aumento do saco aneurismático apresentavam endoleak. CONCLUSÃO: Os pacientes que tiveram dor no pré-operatório, portanto, sintomáticos, apresentaram uma taxa numérica maior do crescimento do saco aneurismático em relação ao grupo que não apresentava sintomas, mas este achado não foi estatisticamente significante. A presença do endoleak não foi a única causa do crescimento dos AAAs. Não houve diferença do PCR colhido no pré-operatório em relação ao crescimento do AAA em ambos os grupos. A hipertensão arterial foi a comorbidades mais frequente na nossa casuística.
The endovascular repair of abdominal aortic aneurysm (EVAR) modified its treatment, reducing the mortality and complications in short-term compared to open repair. Even though, patients need strict follow-up to identify possibly complications. The sac aneurysm enlargement after EVAR is related to the risk of rupture or reintervention, with some preoperative factors can predict this enlargement. OBJECTIVE: Identify if the AAA symptons, especially pain, are predictors of abdominal aortic aneurym sac enlargement after EVAR. METHODS: Retrospective study through the gathering of data about the patientes in follow-up in Botucatu School Medicine. The patients were separated in two groups: G1 – assymptomatics in the preoperative; G2 – syptomatic in the preoperative. Both groups were followed-up for 12 months to the sac enlargement through AngioCT, duplex scan and Reative-C-Protein. RESULTS: 112 patientes were analysed. The age average was 68,6 years. 80% were male and 95% white. Most of them were hypertensive and smoker, 74,1% and 67% respectively. There was 22,3% of endoleaks and 26,8% sac enlargement ratio. 25,3% of the assymptomatics and 30% of the symptomatics had sac enlargement. 19% of the assymptomatics compared with 41,2% of the symptomatics had endoleak. 40% of the patients with sac enlargement had endoleaks. CONCLUSION: The symptomatics preoperative patients has a higher risk compared with assymptomatic group. The endoleak is not the only reason for the AAA sac enlargement. There was no difference between the groups G1 and G2 related to AAA sac enlargement and Reative-CProtein. Hypertension was the most prevalent comorbidity in our study.

Full textThe use the human fetuses for stem cells isolation have ethical limitations. In this context the dog is an excellent candidate to fetal stem cells. Furthermore, these cells can be used in cell therapy of canine diseases We aimed at isolation and comparative characterization of progenitor cells from yolk sac, liver and bone marrow of canine fetuses. Cells were characterized using stem cells antibodies. Differentiation assays as well as karyotype analysis were performed. Teratogenic properties this cells were evaluated. After establishment of primary culture, best proliferation potential was observed in bone marrow progenitor cells. Bone marrow and liver progenitor cells were more efficient in CFU-F assay, then yolk sac progenitor cells. Evidenced by TEM cells with a high nuclear-to-cytoplasmic ratio and cells with cytoplasm rich in organelles. Cells isolated from liver showed epithelial-like morphology and cytoplasm rich in organelles. The yolk sac, liver bone marrow cells reacted positively with nestin and vimentin, being negative to CD45 and CD13 antibodies. Additionally bone marrow progenitor cells were positive to CD44. Bone marrow and liver progenitor cells reacted positively with cytokeratin 18. Yolk sac progenitor cells were positive to ve-cadherin. A few Oct3/4 positive cells were found in yolk sac, liver and bone marrow. Yolk sac and bone marrow progenitor cells showed successful osteogenic, chondrogenic, myogenic differentiation. Differentiation liver progenitor cells were able to bone and muscle cells. The bone marrow progenitor cells were able to produce neuron-like cells. None of progenitor cells showed adipogenic differentiation. The study suggests the presence of mesenchymal-like and epithelial-like progenitor cells. All the karyotype remained and failed to induce the formation of tumors. Stem cells from bone marrow showed high diversity of differentiation than other cell types. It is suggested that these cells are possible candidates for cell therapy.

Full textThe yolk sac plays an important role in embryonic development of all mammals. Its function is being studied, proving to be one of the initials of haematopoiesis. In the period when the placenta is not real yet formed during embryonic development, the yolk sac is the main source of nutrition of the embryo, providing a place for the transfer and synthesis of proteins. Proteins are molecules that govern all cellular functions and are from a chemical structurally the most complex biological molecules. The proteomics is the large-scale study of proteins in a complex biological sample. The aim of this work was make the analisys of present proteins in the yolk sac of bovine embryos by 2D-PAGE two-dimensional electrophoresis. The gels obtained from 2D-PAGE of protein samples contained in the yolk sac of 37 days of pregnancy had about 1230 proteins, and gels of samples from 23 days of pregnancy had about 970 proteins. The yolk sac of 23 days showed essential proteins differentially expressed in stages of development, as Hemogen, protein expressed in stage, responsible for controlling the proliferation and differentiation of hematopoietic cells, the protein acetylgalactosamine glycoprotein-N-3-beta-galactosyltransferase-1, involved in the process of angiogenesis, trombopoiese homeostasis and development of the kidney, the protein factor chorion-specific transcription (GCMa) transcription factor necessary for the development of the placenta. The yolk sac of 37 days showed essential proteins differentially expressed in stages of development , as apolipoprotein E (APOE), which mediates the binding, intersignaling and catabolism of lipoprotein particles, and can serve as a link to the receptor to LDL (apo B/E) and specific receptors for apo E in the liver tissue embryogenesisThese proteins are of vital importance to the development of the embryo until the formation of the placenta.

Full textThe inversion period of the yolk sac as the dynamic which results from this process was studied in 30 female of prea on days 6, 10, 11 to 15, 20, 25, and 30 of gestation. Six groups of animals (one male for five females) were formed and kept in boxes of 5m2. Vaginal cytology was performed daily for detection of copulation. Pregnant females were separated of the other individuals of the group. They were euthanized using a specific anesthetic protocol for collection of the gestational sacs. Then, the material was processed for histology, immunohistochemistry, scanning electron microscopy, and transmission electron microscopy. At days 11 to 13 of gestation was observed the development of the parietal and visceral endoderm delimiting the yolk sac cavity. The parietal endoderm was coating the surface of the fetal side of the chorioallantoic placenta and surrounding the space bounded by the capsular decidua. These endoderm layers showed a prismatic shape and were separated of the trophoblast by a developed Reichert s membrane. The visceral endoderm contained vitelline vessels and villi in some areas. On the 13th day it was possible to establish as a basic condition before the inversion of teh yolk sac, the permanence of at least one of the three elements that characterized the bilaminar omphalopleure. On the 14th day of gestation the complete inversion of the yolk sac, which was characterized by the degeneration of both parietal endoderm and mural trophoblast, coupled with the gradual disappearance of the Reichert s membrane was observed. As a consequence of this, the visceral endoderm constitutes the interface with the uterine epithelium. After the inversion of the yolk sac, the parietal endoderm remained intact was the one which rested on the surface of the chorioallantoic placenta, which showed high columnar cells, characteristic of the pseudostratified epithelium. The visceral endoderm showed numerous apical villi mainly in regions close to the chorioallantoic placenta. The intense vascularization was confirmed by the immunohistochemistry reaction for vimentin associated with the scanning electron microscopy. During the continuous development of the embryo and chorioallantoic placenta it was also observed the development of an important area of apposition of both visceral and parietal endoderm whose proliferative capacity of these cells was demonstrated by immunohistochemistry using PCNA antibody. Therefore, we concluded the inversion of the yolk sac represents an anatomical arrangement in favor of embryonic development as well as an evolutionary characteristic in this rodent specie.
O período de inversão do saco vitelino bem como a dinâmica resultante deste processo foi estudado em 30 fêmeas de preás nos dias 6, 10, 11 a 15, 20, 25 e 30 de gestação. Foram formados seis grupos de animais numa relação de um macho para cinco fêmeas, mantidos em boxes de 5m2. Após formação dos grupos, diariamente eram realizados exames de citologia vaginal, para verificação de cópula, separando-se dos grupos as fêmeas que eram cobertas. A partir da ocorrência da cópula programaram-se as coletas dos sacos gestacionais mediante sacrifício das fêmeas gestantes através de protocolo anestésico específico. O material, então, era processado segundo técnicas para histologia convencional, imunohistoquímica, microscopia eletrônica de varredura e de transmissão. Nos dias de 11 a 13 de gestação observou-se o desenvolvimento dos endodermas parietal e visceral delimitando a cavidade do saco vitelino. O endoderma parietal foi evidenciado revestindo a superfície fetal da placenta corioalantoide bem como contornando o espaço delimitado pela decídua capsular. Estes endodermas apresentaram formato prismático e encontraram-se separados do trofoblasto por uma desenvolvida membrana de Reichert. Já o endoderma visceral continha vasos vitelínicos e possuía vilosidades apenas em determinadas áreas. No décimo terceiro dia, foi possível estabelecer como condição primordial antes da inversão, a permanência de pelo menos um dentre os três elementos que caracterizavam a onfalopleura bilaminar. No décimo quarto dia de gestação verificou-se a inversão do saco vitelino, caracterizada pela degeneração do endoderma parietal e trofoblasto mural, associado ao desaparecimento gradual da membrana de Reichert. Como consequência deste fenômeno, o endoderma visceral passou a constituir interface com o epitélio uterino. Após a inversão, o endoderma parietal que permaneceu íntegro foi aquele que se apoiava na superfície da placenta principal, apresentando células em formato colunar alto e característica de epitélio pseudoestratificado. O endoderma visceral apresentou numerosas vilosidades apicais principalmente em regiões próximas a placenta principal. A intensa vascularização desse endoderma foi evidenciada pela reação imunohistoquímica para vimentina e microscopia eletrônica de varredura. Com o contínuo desenvolvimento do embrião e placenta principal, observou-se o surgimento de importante área de aposição entre os endodermas visceral e parietal cuja capacidade proliferativa destas células foi demonstrada pela reação imunohistoquímica para o PCNA. Por conseguinte, concluiu-se que a inversão do saco vitelino representou uma disposição anatômica favorável ao desenvolvimento embrionário além de uma característica evolutiva nesta espécie de roedor.

Full textCurrently, stem cell therapy have been a useful tool in regenerative medicine with high therapeutic potential due to the capacity for self renewal and differentiation of these cells. In recent years, orthopedics has been seeking new methods of treatment to obtain the effect of repair of articular defects more effectively and without invasive procedures. Therefore, many studies involving cell therapy in order to improve the repair articular are being conducted. The aim of this study was to evaluate the therapy with stem cells from the yolk sac and canine dental pulp in dogs with hip dysplasia by three mobile applications (day 0, 30 and 60, and one day control 90). For the evaluation of the treated animals was set up a control group for each cell type tested, and rated the lameness score, muscular atrophy score, a questionnaire about quality of life, radiographic evaluation, synovial fluidanalysis and blood count. The results showed that there was no statistically significant difference when compared animal treatment and control groups. Comparing the animals, treatment groups showed a statistically significant difference for the animals treated with stem cells from the yolk sac for the animals treated with stem cells from dental pulp. Treatment with yolk sac cells showed better results in Ortolani tests.

Full textThe present Project of the Business Development course 2 of the Peruvian University of Applied Sciences, consists in the creation of a wooden support for bicycles that will be made with OSB boards that ensures high resistance in the supports. It should be noted that we are going to head to Metropolitan Lima in the districts with the largest population in the use of bicycles and that also have access to bicycle paths, such as Surco, La Molina, San Isidro, San Borja and Miraflores, we will also go to socioeconomic sectors A and B, with an age range of 18 to 45 years. The project is viable, since according to the in-depth interview that was carried out, a large percentage of people who use the bicycle as a means of transportation was identified; Part of it, the research also indicates that users have difficulty storing their bikes as they do not have adequate space in their homes. On the one hand, for the start-up of the project an initial investment of S /. 51,884 soles, which will be financed 100% by shareholders without the need to be financed by banks. At the same time, we take into account that the months of December, January, March and July will have high sales, which has proven that the business is profitable. On the other hand, the marketing area will make use of digital advertising, for this we will use web tools such as Facebook, Google Adwords, Landing Page and Community Manager, which allows us to better disseminate the product. The distribution will be coordinated directly with the client through social networks; It is also important to indicate that there will be external distributors such as Maestro and Sodimac.

Full textThe yolk sac is the single attachment embryo present in all species of vertebrate embryos, reptiles, birds and mammals. In domestic mammals the yolk sac is initially large, since these species it is transient. After implantation, appears in the lateral mesenchyme to the notochord cell clusters, called \"blood islands\" that represent the progenitors of vascular and hematopoietic systems: the hemangioblasts. The central islands hemangioblasts form the first blood hematopoietic stem cells, while peripheral hemangioblasts, the angioblastic differentiate into the precursors of blood vessels. The initial development of the yolk sac hematopoietic activity leads to the hypothesis that this tissue is the primary site of development and that hematopoietic stem cells derived from them sow other intraembryos sites. It was observed in the microscopic analysis that there is indeed a relationship between the two lineages. In the analysis of gene expression, some genes expressed by hemangioblasts showed high expression in D+0 and other specific genes also hemangioblasts, but in secondary stages of differentiation as found in the aortic region, the level of hemogenic endothelium showed high levels of expression after 3 days in culture. We therefore conclude that the yolk sac to be the primary site of formation of blood and endothelial cells in the early stages of embryogenesis, for its cells be primitive and therefore do not express markers of mature cells on the surface, these cells become an important source of cells relevant to stem cell therapy for hemophilia and many other human diseases.

Full textIn many species of mammals, the yolk sac is one of the embrionary membranes that plays an important role in the embryo´s initial survival, as well as, in the manufacturing of the necessary proteins for its development. In order to identify the proteins: alfafetoprotein, alfa 1 - antitrypsin, and transferrin present in the cow´s embryo´s yolk sac, 17 bovine embryos were collected in different pregnancy periods. This procedure was performed by Western Blot Technique with a polyacrylamide gel electrophoresis, SDS-PAGE, at 6%. Gels following the electrophoresis, where tainted with Comassie blue, and the membranes of Nitrocellulose, following their transference (the proteins that were present in the gel go to the membrane), with Ponceau. Monoclonal Antibody mouse anti human α-fetoprotein, alphafetoprotein mouse monoclonal antibody, transferrin receptor mouse IgG1, and rabbit polyclonal to alpha 1 antitrypsin were used as primary antibodies, and Peroxidase labelled antimouse e Peroxidase labelled antirabbit e anti-mouse IgG- Alkaline Fosfatase as secundary ones. The membrane´s revelation was of the alcaline fosfatase colormetric type and by ECL. The yolk sac was presented well developed until the 50 days of gestation, where to break of this period the involution process well it is characterized. In some of the yolk sac samples we detected the presence of alfafetoprotein, alfa 1- antitrypsin, and transferrin, however, the bands in some specimens (samples) were weak, demonstrating that the antibodies react with the bovine proteins. The fact that weak bands appeared might be related to a weak cross reaction since we are dealing with a non specific antibody.

Full textIntroduction: Stem cell therapy has been applied as coadjutant or treatment for some diseases or disorders. A range of sources of pluripotent cells have been investigated as placental, umbilical cord, teeth pulp, fat. However pluripotent cell behavior submitted to a concomitant physiological disorder as diabetes has been no fully understood. Methods: We aimed to evaluate proliferative potential, and the characterization of stem cells markers for potential cell differentiation, mitochondrial activity, cell cycle and apoptosis in samples of stem cells from yolk sacs obtained from rats in 15 and 20 gd in normal and hyperglycemic conditions using flow cytometry to analyze cell cycle stages, mitochondrial membrane potential, expression of Stro-1, CD90, Nanog, Oct 3/4, CD117, CD115, CD 44, CD34, VEGF-R1, COX-2, MCP-1, INF-₢ R1, L 1 and phosphorylated Caspase-3. Results: In diabetic groups we observed high levels of mitochondrial inactivity, intensively decreasing in G2/M phase, over expression of caspase, decreased expression of adhesion formation markers such as CD 44, CD 34, and NANOG. Increased pluripotency CD 90 receptor, VEGF-R1, TNF-R1, IL-1, COX-2, Caspese. Discussion: In the last period of gestation diabetes might be associated to permeability deregulation, mitochondrial integrity, cytochrome c release, reduction in the cell cycle progression, apoptosis activation and proliferative capacity decreasing. Conclusion: Diabetes seems to play a negative influence on yolk sac cell behavior in the last period of gestation.

Métodos: O objetivo foi avaliar o potencial de proliferação, e a caracterização de marcadores de células-tronco para diferenciação potencial celular, atividade mitocondrial, ciclo celular e apoptose das células-tronco do saco vitelino obtidos de ratas em 15 e 20 gd em condições normais e hiperglicêmicos usando a citometria de fluxo para analisar as fases do ciclo celular, o potencial da membrana mitocondrial, a expressão de Stro-1, CD90, Nanog, Out 3/4, CD117, CD115, CD 44, CD34, de VEGF-R1, a COX-2, a MCP-1, IFN-₢ R1, L 1 e a caspase-3. Resultados: Nos grupos diabéticos observou-se elevados níveis de inatividade mitocondrial, diminuindo intensamente em fase G2 / M, sobre a expressão de caspase, diminuição da expressão dos marcadores formadores de adesão como CD 44, CD 34, e NANOG. Aumento da Pluripotencia dos receptores CD 90, VEGF-R1, TNF-R1, IL-1, COX-2, Caspese Discussão: No último período de diabetes gestacional pode estar associado à desregulamentação permeabilidade, integridade mitocondrial, liberação de citocromo c, redução da progressão do ciclo celular, ativação da apoptose e diminuição da capacidade proliferativa. Conclusão: Diabetes parece ter uma influência negativa sobre o comportamento das células do saco vitelino nos último período de gestação.

Full textThis consultancy was made to the company Metal SAC, an institution that is in charge of the rental, repair and preventive maintenance services of mining machinery. The company has a cost-based strategy and is part of the Material mining group who have chosen to perform a vertical backward integration giving rise to Metal SAC. The consultancy consisted of the analysis of the processes that involve the operation of the repair shop, from a financial, logistical and commercial point of view; In order to generate gross margin, we sought to improve the processes and the efficiency of the maintenance operation in light of the growth in demand. For this, the internal and external problems of the organization that affect the margin of the operation were identified. The main problem is the loss of profitability in the service, despite the fact that the profits increased due to the increase in demand, the total cost of the service, which is a direct cost, grew in a greater proportion, evidencing the lack of standardization. , definition of processes, rework, erroneous allocation of resources, bad contributions, excess of outsourced processes and the rotation of specialized personnel to new areas of the group that were observed in the diagnostic process. For the implementation of the improvements, a Gantt is presented that will help the operations management to execute the solutions aimed at the standardization, control and continuous evaluation of the process. With the implementation of these solutions, an investment of S / 221,900 is expected, seeking an annual saving of S / 191,893 for the next four years, obtaining a NPV of S / 386,375 with a discount rate of 10% and an IRR of 78%.

Full textBesco is a company dedicated to construction and real estate that has more than 20 years of experience in the field, which has enabled the company to execute multiple large-scale projects in Peru. Nowadays, one of its main projects is the first phase of La Alameda del Rimac (LAR), which consists of four deliverables: three buildings and an urban development. Due to the magnitude of this project, Besco needs to find new management tools that reduce budgets or non-productive expenses in order to improve its profitability, increase the implementation of technology, among other goals. The objective of the consultancy was to identify the main problem that does not allow Besco to achieve its objectives. Therefore, the main causes were analyzed, and then new technologies were proposed to meet its expectations. One finding was that the main problem is the growth of the budget allocated for observations in construction projects, which has generated a stagnation in the company's performance. Through consulting, it was found that the root cause of his problem would be related to inadequate engineering and As-Built management; in other words, the processes involved in the development of the project are inefficient. Based on the external and internal analysis, and the researched literature, the consulting group proposes a feasible technological tool that directly and indirectly affects the costs and times in the project. Also, are included its implementation process and projecting its effects on the budgets.

Full textThis study aimed to quantify Vibrio, Vibrio and sac + sac - and identify the species of Vibrio, in the cultivation of shrimp Litopenaeus vannamei and water where it is grown. Acompanharamse two cycles of cultivation of L. vannamei in three farms (A, B and C), located in river estuaries AcaraÃ, and Coreaà Jaguaribe (EC), August 2005 to October 2006, at the stations of rain and drought. We analyzed 60 samples of shrimp and 240 samples of water from nursery. The tests were made in Standard Plate Count (CPP) of total Vibrio; CPP of colonies of Vibrio sucrose positive and negative, and identification of species in samples of shrimp and water. The minimum value of the CPP of Vibrio in the water samples was 2.0 x 102 CFU / mL in farms A and C in the period of rain and the maximum was 1.42 x 108 CFU / mL in farm B, in the period of summer . The maximum value for CPP of Vibrio in samples of shrimp (post-larva and hepatopÃncreas) was 4.5 x 108 CFU / g in farm B during the summer. The minimum value of sucrose positive Vibrio in hepatopÃncreas was 1.00 x 102 CFU / g in farms A and B in the period of rainfall and maximum was 4.5 x 108 CFU / g in farm B, in the period of summer. The minimum value of sucrose negative Vibrio was 0.98 x 10 CFU / g of hepatopÃncreas in farm A, the maximum period of rain and was 9.50 x 105 C on the farm during the rain. The CPP of Vibrio from water samples and the shrimp was always lower during the rain. Of water samples and the three shrimp farms were isolated 145 strains of Vibrio. Of these, 62 were isolated from the water culture of shrimp and 56 were isolated from shrimp (post-larva and hepatopÃncreas). The farm B showed the largest number of species isolated and identified (11). During esquisa, isolated from the shrimp and water in the nursery, showed a predominance of Vibrio mimicus, followed by V.alginolyticus and V. tubiashii. Of all the farms, A, B and C, Afoi farm that had a nursery with the lowest survival rate of shrimps in despesca: 37.24%, during the chuva.Nem the amount of Vibrio total nor the sucrose positive or negative in hepatopÃncreas of shrimp, influences the rate of survival of animals in the nursery of the farms at the despesca. The greater or lesser diversity of Vibrio in shrimp did not involve a greater or lesser rate of survival of animals in the nursery of the farms at the despesca. However, when the number of Vibrio in the water was high and low diversity, the case of Finance during the rain, the survival rate was affected negatively. The number of Vibrio is proportional to the level of salinity of water. Only data from the enumeration of Vibrio and / or data from the enumeration of Vibrio sucrose positive or negative is not sufficient to assess the likelihood of shrimp in a nursery, will sicken.
