1. CARACTERÍSTICAS MORFOGÊNICAS E ESTRUTURAIS DO SORGO FORRAGEIRO SUBMETIDO A LOTAÇÃO CONTÍNUA COM NOVILHOS DE CORTE SUPLEMENTADOS
Resumo A morfogênese é uma valiosa ferramenta para a compreensão da dinâmica do pasto, porém os estudos morfogênicos referentes à cultura do sorgo ainda são escassos. O objetivo do presente estudo foi avaliar os efeitos de diferentes níveis de suplementação sobre as características morfogênicas do sorgo forrageiro. O experimento foi conduzido na

2. Medium modification with bone morphogenetic protein 2 addition for odontogenic differentiation
Abstract The aim of this study was to evaluate whether medium modification improves the odontogenic differentiation of human dental pulp stem cells (DPSC) in vitro and in vivo. DPSC isolated from human impacted third molar teeth were analysed for clusters of differentiation with flow cytometry. Odontogenic differentiation was stimulated by medium modificatio

3. The ability of mouse nuclear transfer embryonic stem cells to differentiate into primordial germ cells
Nuclear transfer embryonic stem cells (ntESCs) show stem cell characteristics such as pluripotency but cause no immunological disorders. Although ntESCs are able to differentiate into somatic cells, the ability of ntESCs to differentiate into primordial germ cells (PGCs) has not been examined. In this work, we examined the capacity of mouse ntESCs to differe

4. Fetuin-A is related to syndesmophytes in patients with ankylosing spondylitis: a case control study
OBJECTIVES: New bone formation is one of the hallmark characteristics of ankylosing spondylitis, which is thereby associated with syndesmophytes. Fetuin-A is a molecule that is abundantly found in calcified tissues and it shows high affinity for calcium phosphate minerals and related compounds. Considering the role of fetuin-A in the regulation of calcified

5. Productive and morphogenetic responses of buffel grass at different air temperatures and CO2 concentrations
The objective of the present trial was to evaluate the productive and morphogenetic characteristics of buffel grass subjected to different air temperatures and CO2 concentrations. Three cultivars of buffel grass (Biloela, Aridus and West Australian) were compared. Cultivars were grown in growth chambers at three temperatures (day/night): 26/20, 29/23, and 32

6. Morphogenetic characteristics of three Brachiaria brizantha cultivars submitted to nitrogen fertilization
Este estudo teve como objetivo avaliar as características morfogênicas de três cultivares de Brachiaria brizanthasubmetidos à adubação nitrogenada. O delineamento foi em blocos casualizados em esquema fatorial 4x3; três cultivares de B. brizantha - Marandu, Piatã, Xaraés e quatro níveis de nitrogênio - 0, 80, 160 e 240 kg/ha, com três repetiçõe

7. Morphogenesis of native grasses of Pampa Biome under nitrogen fertilization
Morphogenetic and structural characteristics of the native grasses of the Pampa Biome Andropogon lateralis, Aristida laevis, Axonopus affinis, Erianthus angustifolius, Paspalum notatum, Paspalum plicatulum, Piptochaetium montevidense and Sorghastrum pellitum were evaluated as to the effect of nitrogen (N) fertilization (zero and 100 kg N/ha). The experimenta

8. Nitrogen fertilization on the establishment of Arachis pintoi cv. Belmonte
The objective was to evaluate the effect of nitrogen fertilization on the establishment of forage peanut (Arachis pintoi cv. Belmonte) propagated vegetatively. The experiment was conducted in a greenhouse in a completely randomized design with treatments arranged in a 2 × 4 factorial design - two ages (70 and 85 days after planting) and four nitrogen doses

9. Frequencies and intensities of defoliation in Aruana guineagrass swards: morphogenetic and structural characteristics
The objective of this study was to evaluate the morphogenetic and structural characteristics of Aruana guineagrass pastures (Panicum maximum cv. Aruana) subjected to rotational stocking by sheep. The treatments corresponded to grazing when swards reached 95 or 98% of interception of incident light (LI) until post-grazing heights of 10 and 15cm and were alloc

10. Morphogenetic and structural characteristics of guinea grass tillers at different ages under intermittent stocking
The objective of this research was to assess morphogenetic and structural characteristics of tillers of guinea grass cv. Tanzania at different ages. The pastures of guinea grass were managed in six pasture conditions related to the combination of three frequencies (90, 95, and 99% light interception) and two post-grazing heights (25 and 50 cm). In these six

11. Effects of biofertilizer rates on the structural, morphogenetic and productive characteristics of Piatã grass
The objective of this study was to investigate the influence of different levels of biofertilizers from cattle and swine manure on the structural, morphogenetic and productive characteristics of Brachiaria brizantha cv. Piatã. The experiment was arranged in a completely randomized factorial design with split plots. The plots were defined by eight treatments

12. Morphogenesis in guinea grass pastures under rotational grazing strategies
This study was conducted in order to evaluate the morphogenetic and structural characteristics of guinea grass cv. Mombasa under three post-grazing heights (intense - 30 cm, lenient - 50 cm and variable - 50 in spring-summer and 30 cm in autumn-winter) when sward light interception reached 95% during regrowth. Post-grazing heights were allocated to experimen
