Abstract In the mixed systems (beef and grain) of the semiarid Pampa, double purpose wheat use might diminish competition by the soil resource, external inputs into the system and money, which are often associated between winter cereals for grazing and/or grain harvest. In the experimental station of the Asociación de Cooperativas Argentinas in Cabildo (wheat semiarid subregion V S), a trial to evaluate shoot and grain production was conducted. The wheat (Triticum aestivum L.) variety Buck Charrúa, commercially recommended for double purpose use was utilized. Grain production of autumn-sown plots, which were defoliated 0, 1, 2 or 4 times, was compared… More >

Abstract TThe goals of this study were (1) to determinate the cultural practice of Solidago chilensis native Asteraceae from Argentina which have to be used in low maintenance gardening and (2) to describe germination and seedlings of S. chilensis and its morphology type. Germination assay treatments (3 repetitions/50 fruits/year) were intact non-scarified and scarified fruits (achenies), collected in La Mesada, La Calera, Dpto. Colón (Córdoba, Argentina) between 2011-2014. Statistical tests were performed. 50 rhizome cuttings, obtained from mother plants selected in the field, were cultivated in same conditions of the field-substrate with or without rooting solution, and they were cultivated in… More >

Abstract Remodeling of large and small arteries contributes to the development and complications of hypertension. Artery structural changes in chronic sustained hypertension include vascular smooth muscle cells (VSMC) proliferation and extracellular matrix (ECM) modifications. Extracellular constituents such as proteoglycans (PGs), may modulate vascular stiffness and VSMC growth and differentiation. We examined the effect of growth factors on secreted and membrane-bound PGs synthesis by cultured aortic smooth muscle cells (SMC) from 12- to 14- week-old spontaneously hypertensive rats (SHR) and age-matched Wistar rats. After stimulation with platelet-derived growth factor (PDGF-BB), 10% fetal calf serum (FCS) or 0.1% FCS as control, PGs synthesis… More >

Abstract In the present paper we study the possible biological relevance of endogenous jasmonic acid (JA) and exogenous salicylic acid (SA) in a plant-microbial system maize-virus. The virus disease "Mal de Río Cuarto" is caused by the maize rough dwarf virus - Río Cuarto. The characteristic symptoms are the appearance of galls or "enations" in leaves, shortening of the stem internodes, poor radical system and general stunting. Changes in JA and protein pattern in maize control and infected plants of a virus-tolerant cultivar were investigated. Healthy and infected-leaf discs were collected for JA measurement at different post-infection times (20, 40, 60… More >

Abstract Complex III plays a central role in the mitochondrial respiratory chain transferring electrons from ubiquinol to cytochrome c and pumping protons to the intermembrane space, contributing to the protonmotive force. Furthermore, complex III can act as a source of O₂ •- in the presence of ubiquinol and antimycin, an expermiental condition in which the oxidation of the cytochrome b hemes is blocked. The O₂ •- dismutation catalyzed by superoxide dismutase produces H₂O₂, a known second messenger in redox signalling. Results from our laboratory have shown that NO, released from GSNO or from SPER -NO or generated by mtNOS, inhibits electron… More >

Abstract Wheat is one of the most important protein sources for human beings. Several food products are elaborated from this cereal, such as bread. Mexican wheat breeding programs are focused on to identify those genotypes with high yields and bread quality. Therefore, the aim of this study was to evaluate the environmental effects over the Physicochemical and Bromatological quality parameters of Cal Blanco F2011, Matchett F2011 and RSM-Norman F2008 wheats sown at the experimental fields at Mexicali, Baja California, Querendaro, Michoacán and Tarimoro, Guanajuato, Mexico during the autumn-winter growing cycle for two consecutive years (2014-2016) under irrigation conditions.

Abstract Prenatal stimulations have been shown to have long-term effects on at reproductive activity. We evaluated the influence of the prenatal stress on the hypothalamic-pituitary-gonad (HPG) axis in male offsprings from mothers with high number of offsprings per litter (HNL) and low number of offsprings per litter (LNL) after hypothesizing that the number of offsprings per litter may modify the effect of the prenatal stress on the HPG of adult offsprings. Pregnant Wistar rats were used for this study. Immobilization (IMO) stress was used, 30 min, 3 times per week, from the 5th to 21st day of pregnancy. The weight of… More >

Abstract As an important agricultural waste, corn cob is one of the most abundant lignocellulosic biomass. In this work, dilute acid pretreatment using seven different organic acids were compared for compositional analysis of corn cob. The first pKa of organic acids, influenced by the number and type of the side group and distance between two carboxylic groups, played a crucial role in the pretreatment effect. Citric acid was found to have better pretreatment performance than other tested dicarboxylic acids. Under the condition of 30 mM, 160°C and 60 min, the level of xylose reached 22.64 g/L in pretreatment liquid, and the… More >

Abstract Date palm (phoenix dactylifera), which is mostly found in the middle east countries such as Iran, Iraq, Saudi Arabia, and the United States (California) that play a significant role in the economical and the environmental condition in those areas. The main purpose of planting dates is its fruit, which is consumed as fresh, dried or processed forms. There are approximately 100 million date palm trees in the worldwide that 62 million of these trees located in the Middle East and North Africa. In Saudi Arabia only, 15000 tons of date palm leaves is prepared as waste materials. The leaves of… More >
