1. Evaluation of different protocols for culturing mesenchymal stem cells derived from murine bone marrow
ABSTRACT Introduction: Culturing bone marrow mesenchymal stem cells (BM-MSCs) is a key point in different fields of research, including tissue engineering and regenerative medicine and studies of the bone marrow microenvironment. However, isolating and expanding murine BM-MSCs in vitro has challenged researchers due to the low purity and yield of obtained c

2. EFFECT OF THE POSTHARVEST PROCESSING METHOD ON THE BIOCHEMICAL COMPOSITION AND SENSORY ANALYSIS OF ARABICA COFFEE
ABSTRACT The objective of this work was to study the influence of two postharvest processing methods on the biochemical composition and sensory analysis of a Colombian specialty coffee. For this purpose, coffee beans (Coffea arabica) of the Castillo variety were collected and processed using the wet and semi-dry methods, and the drying process was conducted

3. Isolamento e diferenciação das células-tronco da polpa dentária canina em células progenitoras neurais
RESUMO O objetivo deste estudo foi verificar a capacidade de diferenciação das células-tronco da polpa dentária canina em células progenitoras neurais bem como quantificar obtenção e viabilidade celular, durante três passagens em cultura. As células foram extraídas da polpa dentária de dois cadáveres caninos, com aproximadamente dez meses de idad

4. Remoção simultânea de material orgânico, nitrogênio e fósforo em um reator em bateladas sequenciais com biofilme de leito móvel operado pelo processo anaeróbio-anóxico-óxico
RESUMO Neste estudo, foi avaliado o desempenho de um reator em bateladas sequenciais com biofilme de leito móvel operado pelo processo anaeróbio-anóxico-óxico (A2O), aplicado à remoção simultânea de material orgânico, nitrogênio e fósforo de esgoto sanitário. Utilizaram-se dois reatores com volume útil de 36 L cada, sendo que um deles recebeu an

6. Effect of the presence of brood and fungus on the nest architecture and digging activity of Acromyrmex subterraneus Forel (Hymenoptera, Formicidae)
ABSTRACT This study investigated the stimuli that trigger digging behavior in Acromyrmex subterraneus during nest building. The hypothesis was that the presence of the fungus garden and/or brood triggers the excavation of tunnels and chambers. For the experiment, the excavation rate of individually marked workers kept in plastic cylinders filled with soil wa

7. Manipulation of a quasi-natural cell block for high-efficiency transplantation of adherent somatic cells
Recent advances have raised hope that transplantation of adherent somatic cells could provide dramatic new therapies for various diseases. However, current methods for transplanting adherent somatic cells are not efficient enough for therapeutic applications. Here, we report the development of a novel method to generate quasi-natural cell blocks for high-eff

8. Numerical and theoretical studies on cold-formed steel unlipped channels subjected to axial compression
This paper presents both the analytical and theoretical investigations on ultimate load carrying capacity and behaviour of CFS unlipped channels with their ends fixed and subjected to axial compression. The numerical studies have been carried out in the elastic as well as in the plastic ranges of loading. The slenderness ratio of the channels chosen is 40, 8

9. Transmisión de Trichoconiella padwickii a coleóptilos de arroz
With the objective of quantifying the transmission efficiency (TE) from rice seed to coleoptiles, a trial was conducted "in vivo" using seeds of the varieties BRS Taim, Puitá Inta-CL and Irga 424. Seeds were sown in plastic trays containing sterile sand as substrate and incubated in laboratory conditions at 25±2ºC and photoperiod of 12 h. The TE was evalu

10. Overexpression of hsa-miR-125b during osteoblastic differentiation does not influence levels of Runx2, osteopontin, and ALPL gene expression
Multipotent mesenchymal stromal cells (MSCs) were first isolated from bone marrow and then from various adult tissues including placenta, cord blood, deciduous teeth, and amniotic fluid. MSCs are defined or characterized by their ability to adhere to plastic, to express specific surface antigens, and to differentiate into osteogenic, chondrogenic, adipogenic

11. Efecto del tamaño del hábitat en la supervivencia, desarrollo y crecimiento en renacuajos de Engystomops pustulosus (Anura: Leiuperidae) y Rhinella humboldti (Anura: Bufonidae)
Tadpole survival is strongly influenced by environmental factors such as temperature, oxygen, food, larval density, water volume and pond drying. Tadpoles of Engystomops pustulosus and Rhinella humboldti develop in ephemeral habitats with strong differences in their size (space and water volume) around the city of Ibagué, Colombia, and at the campus of the
