25. Hydrogel as mitigator of salt stress during the establishment of Tagetes patula L. seedlings
RESUMO Os hidrogéis favorecem a retenção de umidade no substrato e podem atenuar os efeitos do estresse salino na produção de plantas em vaso. Nesse contexto, buscou-se avaliar o uso do hidrogel para mitigar os danos causados pela salinidade da água de irrigação na emergência, crescimento e índice térmico de mudas de Tagetes patula L. A pesquisa f

26. Salicylic acid alleviates salt stress on guava plant physiology during rootstock formation
RESUMO A goiaba é uma fruta amplamente produzida no Nordeste do Brasil, região que possui fontes de água com altos teores de sais, dificultando a expansão da fruticultura irrigada. Assim, é de extrema importância a busca por técnicas que permitam o manejo dessas águas para a agricultura irrigada. Assim, objetivou-se avaliar os pigmentos fotossintéti

27. Gas exchange and yield of grafted yellow passion fruit under salt stress and plastic mulching
RESUMO A irrigação com água salina é um dos principais fatores que limitam as trocas gasosas e a produtividade do maracujazeiro-amarelo no semiárido do Brasil. A utilização de espécie silvestre de Passiflora ssp. tolerante à salinidade como porta-enxerto e a aplicação de mulching com filme plástico podem atenuar os efeitos do estresse salino. O o

30. Osmotic dehydration kinetics of fresh and frozen blueberries considering volume shrinkage in a novel ternary solution
Abstract Osmotic dehydration is a nonthermal processing technology, that is limited in blueberries because of the osmotic agent, temperature and efficiency. This study was to prepare a novel ternary solution considering low-sugar, low-salt and low-viscosity requirements and to dehydrate blueberries at 20 °C. The mass transfer kinetics of fresh and frozen bl

31. Dextran Sulfate/Pramlintide Polyelectrolyte Nanoparticles as a Promising Delivery System: Optimization, Evaluation of Supramolecular Interactions and Effect on Conformational Stability of the Peptide Drug
In this study, we investigated the feasibility to obtain nanoparticles (NPs) by assembling pramlintide (Pram) with dextran sulfate (DexS), as a new approach for mucosal peptide delivery. DexS/Pram NPs were prepared by dropwise addition of a Pram solution to a DexS solution under magnetic stirring. The physicochemical characteristics of NPs and molecular inte

32. Liquid Phase Nitration of Benzene Catalyzed by a Novel Salt of Molybdovanadophosphoric Heteropolyacid
A highly efficient and reusable catalyst QA-HPMV was successfully prepared by the reaction of quinoline-2-formic acid (QA) with molybdovanadophosphoric heteropolyacid (H4PMo11VO40, HPMV) for the nitration of benzene. The physical and chemical properties of the sample was characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectrosco

33. Maternal Intake of Flaxseed During Lactation and Exercise Training Protect Against Salt Overload-Induced Aortic Remodeling in Adult Offspring
Abstract Background High dietary sodium intake can induce endothelial stiffness even without changes in blood pressure. Objectives To evaluate the effects of exercise training and chronic intake of sodium chloride solution on aortic morphology of male offspring of rat dams who consumed flaxseed during lactation. Methods Female rats were fed with a control

34. SALITRE: O PRODUTO QUÍMICO ESTRATÉGICO NO PASSADO DO BRASIL
Saltpeter demanded for a long-time strategic attention in view of its importance in the form of gunpowder by the governments of many nations. The sources of this mineral in Brazil were almost always associated to the soil in caves, which was extracted because of a limited amount of that precious salt. The first references pointed out that saltpeter was first

35. Can the Impact of the Excessive Use of Salt and its Chronic Consequences be Atenuated by Functional Foods?
Abstract Background Epicardial fat (EF) thickness is a marker of visceral adiposity and consequently considered an important predictive marker of cardiovascular and metabolic risk. Objective To describe echocardiographic features of the heart in an elderly population and to study the correlation between EF thickness and clinical and anthropometric variab
