The simulation of oat grain productivity does not contemplate the use of efficient models that involve important management with meteorological elements. The objective of the study is to propose a mathematical model capable of simulating the oat grain productivity through the management of nitrogen and growth regulator with variables related to the plant and to meteorological elements. In this study, two experiments were conducted in the years of 2013, 2014 and 2015: one to quantify biomass productivity and another to determine grain productivity and lodging at the management doses of nitrogen and growth regulator. The experimental design was a randomized block with four replications in a 4 × 3 factorial scheme for 0, 200, 400 and 600 mL·ha-1 growth regulator doses and 30, 90 and 150 kg·ha-1 nitrogen doses, respectively. During the crop cycles, the meteorological variables thermal sum, radiation and rainfall were quantified. The mathematical model proposed, which combines polynomial regression of the harvest index with multiple linear regression of the biological productivity, is efficient in the simulation of oat grains productivity with the use of growth regulator, nitrogen and meteorological elements. Thus, it adds to the conventional models of simulation and becomes an aid tool for making decisions regarding the management of oats culture.

We previously showed that the increase in nitric oxide (NO) levels and NO synthase (NOS) expression correlate with the progression of reactive astrocytosis and demyelination in the brains of 6-month-old taiep rats. Increased levels of NO can result in high concentration of peroxynitrite and thus cause tissue damage, which consists of lipoperoxidation of the cytoplasmic membrane, such as the myelin, and of apoptotic and necrotic cell-death. On this basis, we studied whether the increased NO production is associated with lipoperoxidation and cell death in the cerebellum and brainstem over the age (1, 3, 6, and 8 months) of taiep rats. The results were compared with those obtained in matched Sprague-Dawley (SD) rats. We measured the levels of nitrites (NO production), malonyldialdehyde, and 4-hydroxyalkenal (lipoperoxidation) in brain tissue homogenates. The three NOS isoforms and cleaved caspase-3 were evaluated by using ELISA and immunostaining techniques. Our results showed that NO production and lipoperoxidation increased in the cerebellum and brainstem as the age of the taiep rats increased compared to SD rats. The overexpression of nNOS and iNOS were in the Purkinje cells, magnocellular neurons, and in oligodendrocytes, whereas the glial cells showed strong cleaved-caspase-3 immunoreactivity. In summary our results suggest that NO plays a role in the demyelination and cell death in the taiep rat.

The acceptability properties, total phenolic content, and antioxidant potential of four (red, green, brown, cream) desi chickpea (Cicer arietinum L.) cultivars from the World Germplasm Bank were evaluated. Protein content of the grains varied from 20.12% to 28.85% (dw), highest for Cream ICC3421. The water absorption capacity (WAC) and cooking time (CT) of the whole grains ranged from 97.7 to 117.5 g water/100 g seeds (ww) and from 109.5 to 193.5 min, respectively;the highest WAC and lowest CT corresponded to Cream ICC3421 cultivar. The total phenolic content (TPC) and total hydrophilic antioxidant activity (AoxA) [oxygen radical absorbance capacity (ORAC) value] of desi chickpea cultivars varied from 746 to 1.286 μg gallic acid equivalents (GAE)/g sample (dw) and from 43.9 to 53.9 μmol Trolox equivalents (TE)/g sample (dw);Brown ICC3512 showed the highest ORAC value. Chickpea cultivars could contribute significantly to the management and/or prevention of degenerative diseases associated with free radical damage.

Atelosteogenesis type II (AO2) and diastrophic dysplasia (DTD) are two recessively inherited, severe skeletal dysplasias caused by mutations in the SLC26A2 gene. AO2 is an invariably lethal condition, while DTD patients may reach adult life, although both diseases have overlapping diagnostic features. Here we report a patient with an intermediate phenotype between AO2 and DTD and present the successful application of preimplantation genetic diagnosis (PGD) in this situation. Sequencing of SLC26A2 alleles in the infant identified two compound heterozygous mutations, ***178Ter and ***279Trp, of paternal and maternal origin, respectively. At request from the parents, PGD was developed by haplotype mapping of parental SLC26A2 alleles in eleven five-day embryos. Transference to the mother was attempted twice, finally resulting in pregnancy and delivery of a healthy baby. This exemplifies the utility of PGD for inherited lethal conditions with a significant risk of recurrence, and highlights the importance of accurate diagnosis of skeletal dysplasias with prenatal manifestation.

Trichomonas vaginalis, a protist parasite of the urogenital tract in humans, is the causative agent of trichomonosis, which in recent years have been associated with the cervical cancer development. In the present study we analyzed the modifications at the junctional complex level of Caco-2 cells after interaction with two isolates of T. vaginalis and the influence of the iron concentration present in the parasite’s culture medium on the interaction effects. Our results show that T. vaginalis adheres to the epithelial cell causing alterations in the junctional complex, such as: (a) a decrease in transepithelial electrical resistance; (b) alteration in the pattern of junctional complex proteins distribution as observed for E-cadherin, occludin and ZO-1; and (c) enlargement of the spaces between epithelial cells. These effects were dependent on (a) the degree of the parasite virulence isolate, (b) the iron concentration in the culture medium, and (c) the expression of adhesin proteins on the parasite surface.

Here we investigated the effects of chronic treated with resveratrol, a polyphenol (3,4’,5-trihydroxystilbene) found in more than 70 plant species and food products such as red grapes, berries and peanuts, or N-PEP-12, a mix of peptides, on arteries in aging rats. Aging rats have shown endothelial dysfunction. Aged Sprague-Dawley rats (18 months old) were treated with resveratrol (20 mg/kg/day by gavage) or N-PEP-12 (60 mg/kg/day by gavage) for 10 weeks. 24 hours after the last administration of resveratrol or N-PEP-12, the animals were weighed and diastolic and systolic blood pressure was measured by tail-cuff plethysmography. Thoracic and abdominal aorta artery segments were obtained from resveratrol-, N-PEP-12-and vehicle-treated rats and were mounted in isometric tension for isolated vessels. We found that resveratrol and N-PEP-12 improved acetylcholine-induced relaxation in the old animals. These results suggest that chronic administration of resveratrol or N-PEP-12 may in part reduce endothelial dysfunction in the aging.

The Schinus terebinthifolius Raddi is a native plant of South America popularly known in Brazil as aroeira. It is a medium-sized plant, which demonstrates a high adaptive potential in various environments, besides having various medicinal properties such as anti-inflammatory and antidiarrheal. Bacterial susceptibility tests were carried out and the minimal inhibitory concentration (MIC) was obtained. The results were interpreted based on the conventionally microbiological protocols and data from the CLSI. For the microbiological tests, microorganisms obtained from the American Type Culture Collection (ATCC), specifically, (Pseudomonas aeruginosa, Staphylococcus aureus and Encherichia coli) were used. Of the tested bacterial strains, only the Staphylococcus aureus 6538 presented susceptibility to the aroeira’s hydroalcoholic extract, forming zones of inhibition of 8.0 mm of diameter up to the MIC of 35.3 mg/mL, while the other tested strains showed to be resistant in all the concentrations of hydroalcoholic extract of the Schinus terebinthifolius Raddi bark. Our aim is to analyze the “in vitro” antibacterial potential of the 70% hydroalcoholic extract of the Schinus terebinthifolius Raddi.
