Abstract “Frontiers in Fontan Failure” was the title of a 2015 conference sponsored by Children’s Healthcare of Atlanta and Emory University School of Medicine. In what is hoped to be the first of many such gatherings, speakers and attendees gathered to discuss the problem of long-term clinical deterioration in these patients. Specific focuses included properly defining the problem and then discussing different treatment strategies, both medical and surgical. The health of the liver after Fontan palliation was a particular point of emphasis, as were quality of life and future directions. More >

Abstract Background: Stent implantation is the treatment of choice for adolescents and adults with aortic coarctation (CoAo). Despite excellent short-term results, 20%–40% of the patients develop arterial hypertension later in life, which was attributed to inappropriate response of the aortic baroreceptors to increased stiffness of the ascending aorta (ASAO), either congenital or induced by CoAo repair. In particular, it has been hypothesized that stent itself may cause or sustain hypertension. Therefore, we aimed to study the hemodynamic and structural impact following stent implantation in the normal aorta of a growing animal.
Methods: Eight female sheep completed the study… More >

Abstract Knowledge of the genetic components of agronomic traits is an important factor to characterize landraces of maize to make them useful in plant breeding programs. The objective of this work was to know the genetic action and combining ability of several agronomic traits of five maize races and their crosses. Maize landraces analyzed were Jala, Tuxpeño, Celaya, Pepitilla and Dulce. Plant height, days to male and female flowering date after planting, and dry matter and grain yields were recorded. Those variables showed highly significant differences among genotypes. With the exception of dry matter yield, the More >

Abstract Understanding the genetic control of traits associated with yield helps breeders to utilize their germplasm in a more efficient and consistent manner and to make good choices in breeding programs. The current study was carried out to study the genetic control of some quantitative traits in bread wheat (Triticum aestivum L.) and to examine plant responses under full irrigation and drought stress conditions. For this purpose, six generations derived from a cross between two lines (Bezostaya as tolerant parent and 518 as a susceptible parent) were evaluated for grain yield (GY), plant height (PH), peduncle (PL)… More >

Abstract Tagetes minuta L. (Asteraceae) is an annual herb that is of great interest due to the bioactive properties of its essential oil (EO) and its industrial use. In Argentina, 0.5 tons/year of EO are obtained from wild populations and commercialized with a value of 80-120 US$/kg. The introduction of the species in culture, and the initiation of a process of domestication, selection and breeding material aimed at generating higher yields and quality of EO as an alternative to wild collection. The goal of this work was to generate a population with a broad genetic base to… More >

Abstract Two field experiments were carried out in a semiarid region of Argentina over a soybean (Glycine max L. Merrill) field. The sites of study were San Adolfo (39˚ 23’ S, 62˚ 22’ W, 22 m.a.s.l.) and Nueva Roma (38˚ 29’ S, 62˚ 39’ W, 70 m.a.s.l.). Soybeans were planted on Jan 4 (San Adolfo) and Nov 27 (Nueva Roma) in 0.75 m wide rows and at 400000 pl/ha during two consecutive growing seasons. Energy balance and evapotranspiration (ET) were estimated during the reproductive stages from full bloom (R2) to full maturity (R8). In Nueva Roma ET… 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 More >

Abstract The objective of this work was to study the effect of a controlled fire and/or roller-chopping on foliar cover and density of the most conspicuous woody and forage perennial grass species in the south of the Phytogeographical Province of the Monte, Argentina. All control treatments reduced the woody species mean percentage cover. This reduction persisted during the whole study period. Nevertheless, the woody species tended to recover their percentage cover towards the end of study. At the end of the study period, significant differences (P<0.05) were only detected between the control and controlled burn plus… More >

Abstract Among the different types of abiotic stresses, water is the most damaging for crops. In the current research, the effect of water stress, induced with Polyethylene Glycol 8000 (PEG8000) and Sodium chloride (NaCl) solutions, was studied in maize genotypes. A randomized block design (RBD) with a factorial arrangement and four replications of 25 seeds each was used. The studied maize genotypes were RC₂C39, RC₂C51 (wild varieties of the State of Tabasco backcrossed with the endogamic line CML247 of the International Center for the Improvement of Maize and Wheat), wild Tamulte, VS536, and Asgrow 7573 hybrid, study… More >

Abstract Soybean root and stem rots caused by soil-borne pathogens are diseases commonly found in soybean fields, and one of the most important causes of crop losses. In the present study, the mycelial sensitivity of Fusarium virguliforme, F. tucumaniae, Sclerotinia sclerotiorum and Macrophomina phaseolina was evaluated on potato dextrose agar media (25 mL) supplemented with different concentrations of manganese phosphite (MnPhi) diluted in water (0, 25, 37.5, 50, 100, 200, 300, 400, 500, 800 and 1000 μg/mL). Mycelial growth sensitivity was analyzed using logarithmic linear regression analysis. The MnPhi concentration needed to inhibit 50% of the mycelial growth (IC₅₀) More >
