Abstract Progenitor cells play an important biological role in tooth and bone formation, and previous analyses during bone and dentine induction have indicated that they may be a good alternative for tissue engineering. Thus, to clarify the influence of the microenvironment on protein and gene expression, MDPC23 cells (mouse dental papilla cell line) and KUSA/A1 cells (bone marrow stromal cell line) were used, both in vitro cell culture and in intra-abdominal diffusion chambers implanted in 4-week-old male immunodefficient mice (SCID mice). Our results indicate that KUSA/A1 cells differentiated into osteoblast-like cells and induced bone tissue inside the chamber, whereas, MDPC-23 showed… More >

Abstract Color is one of the factors used in quality estimation in many agricultural and food products. Currently, the evaluation of color depends on judgments made by human experts. These are subjective and inevitably affected by physical, physiological and environmental conditions. Suitable instrumental is required to provide objectivity and coherence to color measurements and quantitative expressions. It would be very useful to have tools that allow both practical and precise approaches to chromatic evaluation of products for human consumption. This work suggests a methodology which might contribute to solve that constraint and the analysis of environmental influences on this character in… More >

Abstract Sunflower oil is naturally rich in both unsaturated fatty acids and numerous minor components, with high levels of α-tocopherol and phytosterols that could play an important role in plant protection. These micronutriments, tocopherols and phytosterols, also exhibit health benefits for humans including reducing both cardiovascular diseases and aging disorders. α−Tocopherol represents more than 95% of total sunflower tocopherol and has the greatest vitaminic activity. Furthermore, this oil contains high amounts of β-sitosterol which is a promising health beneficial phytosterol. The objective of this study was to compare the content and composition of fatty acids, tocopherols and phytosterols in sunflower oil… More >

Abstract The halophytic community of Salitral de la Vidriera (Buenos Aires Province, Argentina) has species with different morphoanatomical functional traits. The aim of this study was to compare these traits in four species, two Asteraceae (Baccharis spartioides and B. tenella) and two Frankeniaceae (Frankenia juniperoides and F. pulverulenta). Leaves and stems were treated under traditional techniques for anatomical study. Leaves the of Asteraceae and F. pulverulenta were amphistomatic while in F. juniperoides they were hypostomatic. All species showed trichomes and only the Frankeniaceae had salt glands. The mesophyll was isolateral in Asteraceae, and dorsiventral in Frankeniaceae; the number of foliar vascular… More >

Abstract In semiarid regions rainfall is often scarce and erratic in space and time, making valuable the exploration of news genotypes with superior behavior in dry land systems. Tricepiro (X Triticosecale Wittmack x X Agrotriticum Ciferri & Giacom) is a synthetic cereal with long cycle and high biomass production in semiarid environments. However its performance under controlled water stress has not yet been evaluated. The aim of this work was to investigate the effect of water stress on tricepiro genotypes in comparison with their progenitors: triticale and trigopiro. Morphophysiological traits related to forage yield were evaluated in the greenhouse and the… More >

Abstract We conducted a comparative study from 2008 to 2011 to study the adaptability and stability of grain yield of upland rice in two regions of Campeche, Mexico. The individual and combined statistical analysis, showed highly significant differences in grain yield of different genotypes in both regions. The experimental error variance was uniform, both effects of repetition/location and variety/location were highly significant. The results of analysis for grain yield stability parameters showed highly significant effects for 12 treatments, and significant for one. Eighteen genotypes showed a significant variation in the effects of deviation from the regression parameters of stability. The highest… More >

Abstract Cococarpus lancifolius Engl. grows wild in Djibouti, Somalia and East Africa, and South Asia. The species was introduced into Kuwait, where it is exposed to several stresses: oil pollution, salinity, high temperature and harsh climatic conditions. These conditions are prevalent in its semi-arid environment. In this study, the impact of salinity (2, 6 and 10%), temperature (20, 30 and 40 °C), polyethylene glycol (10, 30 and 60%) and drought has been investigated on C. lancifolius. Proline (Pro) accumulation (5.5 ± 0.03 µg/g dry weight; p≤0.05-0.005), protein (16.47 ± 0.052 mg/g; p≤0.001), free amino acids (10.92 ± 0.082 mg/g; p≤0.006) and… More >

Abstract Macrophytes of inland waters are a group of great biological interest. Although lentic systems are ideal for their growth, their presence is not so evident in oligotrophic water bodies, proliferating largely in areas with some level of contamination. A useful tool to determine the presence of a regulatory factor in the composition of these and other biological communities is the use of null models. This analysis was applied based on the co-occurrence of species through a matrix of presence and absence, with the purpose of determining the presence of randomness in species associations. The three models tested, determined the presence… More >

Abstract Five genotypes of amaranth were evaluated: four of Amaranthus hypochondriacus L. (collect 153-5-3, 653, 655 and Criollo Tlaxcala) and one of A. cruentus L. genotype 33. Studies were conducted in the cycle of spring-summer (PV) 2000 in Marín, N. L., and PV 2001 and PV 2002 in El Valle del Guadiana, Dgo. A completely randomized design with two repetitions was used, with factorial arrangement using split-plots, divided in space and time. The study population densities (DP) were 125000; 62500; 41666; 32500 and 18666 plants/ha. They analyzed (1) the stability of the genotypes exposed to different environments following Eberhart & Russell… More >
