1. Sensitivity of forage turnip to the herbicide tepraloxydim
ABSTRACT The objective of this study was to evaluate the responses of Raphanus sativus to the application of the herbicide tepraloxydim by analyzing photosynthetic and biometric characteristics of the plants. The experiment was conducted in a greenhouse and treatments were instituted when the plants had five expanded leaves. The herbicide tepraloxydim was ap

2. BROMELAIN SEPARATION AND PURIFICATION PROCESSES FROM PINEAPPLE EXTRACT
Abstract The concern about the effective use of agro-industrial residues from the food industry has increased. Bromelain is an enzyme mainly obtained from the pineapple plant (A. comosus), including its parts normally considered as waste. It is a high value-added product with a wide variety of applications such as in food, cosmetic and pharmaceutical industr

4. Experimental reproduction of cyanogenic poisoning by star grass (Cynodon nlemfuensis Vanderyst var. nlemfuensis cv. “Florico”) in cattle
RESUMO: Descreve-se a reprodução experimental da intoxicação cianogênica por grama estrela (Cynodon nlemfuensis vanderyst var. nlemfuensis cv. ‘Florico’) em bovinos. A grama estrela foi plantada em quatro piquetes em área sombreada (1, 2, 3 e 4) e em três piquetes em área ensolarada (5, 6 e 7) e foram adubados com o equivalente a 0, 750, 200 ou 1

5. In vitro hypoglycemic effects of unripe and ripe fruits of Musa sapientum
ABSTRACT The present study was undertaken to verify the hypoglycemic potential of unripe and ripe fruit extracts of Musa sapientum by using various in-vitro techniques, namely glucose adsorption capacity, glucose diffusion, amylolysis kinetics and glucose transport across the yeast cells. The results revealed that the unripe and ripe fruit extracts of Musa s

6. Plant proton pumps as markers of biostimulant action
ABSTRACT A standard protocol to evaluate the effects of biostimulants on plant physiology is still lacking. The proton pumps present in the vacuolar and plasma membranes are the primary agents responsible for the regulation of the electrochemical gradient that energizes the nutrient uptake system and acid growth mechanism of plant cells. In this study, two o

7. Mechanisms of growth inhibition of Phytomonas serpens by the alkaloids tomatine and tomatidine
Phytomonas serpens are flagellates in the family Trypanosomatidae that parasitise the tomato plant (Solanum lycopersicum L.), which results in fruits with low commercial value. The tomato glycoalkaloid tomatine and its aglycone tomatidine inhibit the growth of P. serpens in axenic cultures. Tomatine, like many other saponins, induces permeabilisation of the

8. Plant physiology as affected by humified organic matter
Since the beginning of Human civilization, the soil organic matter has been used as plant growth promoter and/or regulator. Indeed, early in plant science history, even before the auxin concept has been established, the term "auximones" was coined to describe plant growth promoting humic acids derived from peat. Despite of this, until the end of the 20th cen

9. EFEITO in vitro DE Paullinia cupana NO METABOLISMO OXIDATIVO DE ESPERMATOZÓIDES HUMANOS EXPOSTOS AO CLORETO DE METILMERCÚRIO / EFFECT OF Paullinia cupana in vitro oxidative metabolism HUMAN SPERM EXPOSED TO CHLORIDE METHYLMERCURY
Investigations suggests that methylmercury (MeHg) toxicitiy is related to oxidative stress promotion caused by lipid peroxidation of cell membranes as well as genotoxicity. The methylmercury (MeHg) exposition causes production of adverse effects as deterioration of semen quality, testicular degeneration, and male reproductive failure. Since human sperm is a

10. Aproveitamento de membranas de osmose inversa descartadas da indústria para o reuso da purga de torres de resfriamento
Reverse osmosis plants use new membranes to produce demineralized water. After a period of three to five years, the membranes are replaced by news ones due to levels of treatment which are not suitable for production of water with the desired characteristics. This process generates a lot of rejected modules causing an environmental problem. The present work

11. Antioxidant effects of crude extracts from Baccharis species: inhibition of myeloperoxidase activity, protection against lipid peroxidation, and action as oxidative species scavenger
The objective of this study was to show a comparison of the antioxidant properties of aqueous and ethanolic extracts obtained from Baccharis articulata (Lam.) Pers., Baccharis trimera (Less.) DC., Baccharis spicata (Lam.) Baill. and Baccharis usterii Heering, Asteraceae, by several techniques covering a range of oxidant species and of biotargets. We have inv

12. Inoculation with mycorrhizal fungi modifies proline metabolism and increases chromium tolerance in pepper plants (Capsicum annuum L.)
In general, heavy metals interfere with several physiological processes and reduce plant growth. Plants naturally establish symbiotic associations with soil microorganisms, such as mycorrhizal fungi. The aim of this research was to determine if inoculation with mycorrhizal fungi increases tolerance to Cr, evidenced by growth and biochemical parameters and th
