1. Effects of Human Umbilical Cord Mesenchymal Stem Cells on Renal Ischaemia-reperfusion Injury in Rats
Objective This study aims to observe the function of umbilical cord-mesenchymal stem cells (UC-MSCs) labelled with enhanced green fluorescent protein (eGFP) in the repair of renal ischaemia-reperfusion (I/R) injury, to determine the effects on inflammatory cascade in an established rat model and to explore possible pathogenesis. Materials and Methods Si

2. Dosagens de melatonina e de citocinas de acordo com a via de parto / Melatonin and cytokines concentrations in accordance with the mode of delivery
Objetive: To evaluate the profile of pro-inflammatory cytokines and the melatonin level in maternal and umbilical cord blood samples in accordance with the mode of delivery. Methods: Between March 2010 and September 2010, a prospective observational study was conducted at University Hospital of University of São Paulo. Cytokines (IL-1, IL-6, TNF) and melato

3. Comparing two human umbilical cord mesenchymal stem cell isolation protocols
Human umbilical cord is a rich source of mesenchymal stem cells (MSCs) as reported in many studies. Many techniques are used to obtain these cells and their variations are related to the part of the tissue from which the stem cells can be extracted (umbilical vein, arteries, Wharton’s jelly or the whole umbilical cord - UC). In this sense, it is really imp

4. Identification of differentialy express genes during the differentiation of stem cells and characterization of mesenchymal progenitor cells / Identificação de genes diferencialmente expressos durante diferenciação de células-tronco e caracterização de células progenitoras mesenquimais
Diabetes mellitus (DM) defines a number of pathologies caused by the lack or deficient action of the insulin hormone. DM1 is caused by an auto-immune attack to insulin secreting β-pancreatic cells, while DM2 is related to ageing and obesity. Pancreas and islet allo-transplantation constitute therapeutic alternatives, but severe organ shortage and the ab

5. Medidas ultra-sonograficas da secção transversal do cordão umbilical e de seus vasos, segundo idade gestacional, em gestações de baixo risco
Introdução: mais recentemente, demonstrou-se que o diâmetro do cordão umbilical pode se modificar nos casos de diabetes mellitus, pré-eclâmpsia, restrição de crescimento intra-uterino e baixo peso ao nascimento, podendo talvez ser utilizado como um marcador para detecção precoce destas condições. Objetivo: obter intervalos de referência das medi

6. A subplacenta da paca (Agouti paca, Linnaeus 1766) / The subplacenta of the paca (Agouti paca, Linnaeus 1766)
The rodents of suborder hystricomorph, in which is classified the Agouti paca, present hemochorial type placentation and develops an unique structure known as subplacenta. In spite of many report of its presence in several species, the possible functions of this structure related to placenta and pregnancy remains speculative, mainly due to the diversity of f

7. Placentation in rock cavies, Kerodon rupestris (Wied, 1820) / Placentação em mocós, Kerodon rupestris Wied, 1820
Placentation studies of fourteen rock cavy females in different gestation phases were conducted. Females were pre-anesthetized associating ketamine chloridrate (15mg/kg) and midazolan (1mg/kg). Soon afterwards, they were anesthetized by isoflurane inhalation in association with oxygen at 100% saturation. After anesthesia, the surgery allowed to exhibit fetal

8. Isolation and culture of umbilical vein mesenchymal stem cells
Bone marrow contains a population of stem cells that can support hematopoiesis and can differentiate into different cell lines including adipocytes, osteocytes, chondrocytes, myocytes, astrocytes, and tenocytes. These cells have been denoted mesenchymal stem cells. In the present study we isolated a cell population derived from the endothelium and subendothe

10. Contraction of human umbilical artery, but not vein, by oxygen.
The O2 tension of umbilical arterial blood in utero is 15 mmHg. The contractile effect of increasing the O2 tension above this value was studied quantitatively in vitro in preparations of human umbilical artery and vein. The umbilical arterial smooth muscle was contracted in a concentration-related manner by stepped increments in O2 tension. The threshold fo

11. Extraplacental transfer of water in the sheep.
1. Ten pregnant ewes were operated on at 130 days of gestation. The fetal trachea was intubated with a double-lumen tube, an inflatable occluder was placed around the umbilical cord, vascular catheters were placed in the fetal carotid artery and jugular vein and in the maternal jugular vein, and multiple catheters were placed in the amniotic and allantoic sa

12. Activation of lymphocytes
The technique involved in studying the activation of lymphocytes in the resting form, and their recognition as dividing and functional cells was studied, using phase contrast and agar as well as fluid culture. Standardization of technical methods was found to be essential, and the effect of variables was studied. Lymphocytes from human umbilical cord vein bl
