1. Quality of sunflower seeds in function of thickness classification and sowing under speed variation of the seeder-fertilizer
ABSTRACT The objective was to evaluate the quality of sunflower seeds classified according to their thickness and passed through the seeder-fertilizer dosing system under variation of the travel speed. A lot of M734 was classified by thickness passing the seeds through a set of oblong-hole sieves and two thicknesses were selected. A portion of the seeds with

3. What is the cause of low seed germination of Zanthoxylum rhoifolium Lam.?
ABSTRACT This study aimed to determine the main causes of low germination of Zanthoxylum rhoifolium Lam. (Rutaceae) seeds. Initially, the physical and physiological qualities were evaluated in seeds from four areas (lots) (Step I). Then, tests were performed (Step II) to determine physical dormancy (imbibition in water and methylene blue), physiological (ger

5. Long non-coding RNA HOTAIR induces the PI3K/AKT/mTOR signaling pathway in breast cancer cells
SUMMARY OBJECTIVE: The phosphoinositide 3-kinase/protein kinase AKT/mammalian target of rapamycin signaling pathway is essential for proper cellular metabolism and cell growth. However, aberrant activation of this pathway has been linked to the progression and metastasis of breast cancer. Recently, the role of long non-coding RNAs in interfering with the ce

7. Avaliação da atividade funcional dos neutrófilos sanguíneos em ovelhas primíparas e pluríparas da raça Lacaune
ABSTRACT This study aimed to evaluate the neutrophil oxidative metabolism and phagocytosis of Zymonsan particles of primiparous and pluriparous Lacaune ewes during the first 30 days after lambing. A total of 20 ewes were evaluated, 10 primiparous (GPR) and 10 pluriparous (GPL). Evaluation of basal oxidative metabolism was performed using the nitroblue tetraz

8. Seed quality of 22 quinoa materials (Chenopodium quinoa Willd.) from the department of Boyacá
ABSTRACT Chenopodium quinoa Willd. is a pseudocereal with seeds that are a rich source of vitamins and minerals. However, there are few studies on quinoa seed quality, especially for the Colombian germplasm. So, the objective of this research was to determine the quality of 22 quinoa materials from the Department of Boyacá by evaluating the physical (color,

9. Copaifera multijuga, Copaifera pubiflora and Copaifera trapezifolia Oleoresins: Chemical Characterization and in vitro Cytotoxic Potential against Tumoral Cell Lines
Copaifera species (Fabaceae) comprises approximately 70 species of large trees, from which 16 can be found in Brazil. The oleoresins obtained from their trunk are widely used in Brazilian folk medicine, which display important antitumoral potential. Chemically, these oleoresins are mainly composed of a mixture of sesquiterpenes and diterpenes. In this paper
