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.

The role of plant tyrosyl-DNA phosphodiesteritdase 1a in genome stability is studied using a Medicago Etruncatula Mt Tdp1a-depleted line. Lack of Mt Tdp1 a results e in a 39% reduction of methylated cytosines as compared thto control. RNA-Seq analyses revealed that 11 DNA transto posons and 22 retrotransposons were differentially exrpressed in the Tdp1a-2a line. Among them all, DNA etttransposons（Mu DR, h AT, DNA3-11_Mad） and seven retroetransposons（LTR（Long Terminal Repeat）/Gipsy, LTR/Copia,LLTR and Non LTR/L1） were down-regulated, while the15 retrotransposons were up regulated. Results suggest that the occurrence of stress-responsive cis-elements as well as changes in the methylation pattern at the LTR promoters might be responsible for the enhanced retrotransposon transcription.

Objective: To isolate Candida albicans(C. albicans) from the urine of hospitalized patients and assess the virulence factors and antifungal susceptibility profiles of the isolates.Methods: Yeasts were identified using the chromogenic medium CHROMagar?, the VITEK~?2 system, hypertonic Sabouraud broth, tobacco agar, polymerase chain reaction,and DNA sequencing. The evaluated virulence factors were proteinase production,phospholipase production, and biofilm production on polystyrene. The broth microdilution technique was used to determine the minimum inhibitory concentration.Results: All yeasts isolated from urine were identified as C. albicans using both classical and molecular methods. Although 91.3% of the isolates showed no phospholipase activity, 56.5% showed strong proteinase activity and 91.7% produced biofilm. All microorganisms were sensitive to fluconazole, voriconazole and amphotericin B, but 56.5% of the yeasts showed resistance to itraconazole.Conclusions: C. albicans isolates from urine have a high capacity for virulence and can be associated with infectious processes. Furthermore, the high percentage of isolates resistant to itraconazole is important because this antifungal agent is commonly used to treat fungal infections in the hospital environment.

Triiodothyronine and breast cancer

The thyroid hormones(THs), triiodothyronine(T3) and thyroxine(T4), are essential for survival; they are involved in the processes of development, growth, and metabolism. In addition to hyperthyroidism or hypothyroidism, THs are involved in other diseases. The role of THs in the development and differentiation of mammary epithelium is well established; however, their specific role in the pathogenesis of breast cancer(BC) is controversial. Steroid hormones affect many human cancers and the abnormal responsiveness of the mammary epithelial cells to estradiol(E2) in particular is known to be an important cause for the development and progression of BC. The proliferative effect of T3 has been demonstrated in various types of cancer. In BC cell lines, T3 may foster the conditions for tumor proliferation and increase the effect of cell proliferation by E2; thus, T3 may play a role in the developmentand progression of BC. Studies show that T3 has effects similar to E2 in BC cell lines. Despite controversy regarding the relationship between thyroid disturbances and the incidence of BC, studies show that thyroid status may influence the development of tumor, proliferation and metastasis.
