1. Ameliorative effects of TiO2 nanoparticles and sodium nitroprusside on seed germination and seedling growth of wheat under PEG-stimulated drought stress
Resumo: A germinação de sementes e o crescimento inicial de plântulas são sensíveis ao estresse hídrico no trigo. O delineamento experimental foi inteiramente casualizado, com três repetições, para estudar os impactos de nanopartículas de TiO2 (NPs de TiO2: 0, 500, 1000 e 2000 mg.L) e nitroprussiato de sódio (SNP: 0 e 100 μM), como NO doador, na

3. Contents of Pigments and Activity of Antioxidant Enzymes in Rice Plants Pre-Treated with Sodium Nitroprusside and Exposed to Clomazone
RESUMO: O pré-tratamento das sementes de arroz com nitroprussiato de sódio (SNP) foi usado para investigar o efeito do óxido nítrico exógeno sobre o conteúdo de pigmentos e a atividade de enzimas antioxidantes durante a inibição da rota 2-C-metil-D-eritritol 4-fosfato (MEP), pelo herbicida clomazone. As sementes foram embebidas em solução de SNP (2

4. Effect of cyanide by sodium nitroprusside (SNP) application on germination, antioxidative system and lipid peroxidation of Senna macranthera seeds under saline stress
Resumo: Os efeitos dos doadores de NO na germinação sob estresse salino têm sido muito investigados para muitas espécies, entretanto, há relatos de que o efeito causado pelos doadores são efeitos do cianeto presente. O objetivo deste estudo foi avaliar os efeitos do SNP na germinação, no sistema antioxidativo e na peroxidação lipídica de sementes

5. The role of potassium channels in the endothelial dysfunction induced by periodontitis
Abstract Objective: Periodontitis is associated with endothelial dysfunction, which is clinically characterized by a reduction in endothelium-dependent relaxation. However, we have previously shown that impairment in endothelium-dependent relaxation is transient. Therefore, we evaluated which mediators are involved in endothelium-dependent relaxation recove

6. Effects of sodium nitroprusside in the prevention of schizophrenia-like symptoms induced by ketamine – A translational double-blind study
Abstract Background: Recent evidence has shown improvements in schizophrenia symptoms after the infusion of sodium nitroprusside (SNP), a nitric oxide (NO) donor. In the rat model of schizophrenia using ketamine injection, pretreatment with SNP seems to prevent behavioral changes associated with positive symptoms for up to one week. Objective: We investiga

7. A Potential Visible-Light NO Releaser: Synthesis, Reactivity and Vasodilator Properties
The cis-[Ru(bpy)2(4-bzpy)(NO)](PF6)3 complex was prepared (4-bzpy = 4-benzoylpyridine), and characterized by UV-visible, infrared and nuclear magnetic resonance (NMR) spectroscopies and electrochemical techniques. The reaction with cysteine was preliminarily investigated, aiming to shed light on the potential biological mechanism for NO or HNO release mediat

8. Sodium nitroprusside has leishmanicidal activity independent of iNOS
Abstract: INTRODUCTION: Leishmaniasis is a zoonotic disease caused by protozoa of the genus Leishmania . Cutaneous leishmaniasis is the most common form, with millions of new cases worldwide each year. Treatments are ineffective due to the toxicity of existing drugs and the resistance acquired by certain strains of the parasite. METHODS: We evaluated the

9. 7-Chloroquinoline-1,2,3-triazoyl Carboxylates: Organocatalytic Synthesis and Antioxidant Properties
We describe herein our results on the synthesis and antioxidant properties of 7-chloroquinoline-1,2,3-triazoyl-4-carboxylates. This class of compounds have been synthesized in moderated to excellent yields by the reaction of 4-azido-7-chloroquinoline with a range of β-ketoesters in the presence of a catalytic amount of pyrrolidine (10 mol%). The synthesized

10. Nitric oxide reduces oxidative damage induced by water stress in sunflower plants
Drought is one of the main environmental constraints that can reduce plant yield. Nitric oxide (NO) is a signal molecule involved in plant responses to several environmental stresses. The objective of this study was to investigate the cytoprotective effect of a single foliar application of 0, 1, 10 or 100 µM of the NO donor sodium nitroprusside (SNP) in sun

11. Effects of different frequencies of transcutaneous electrical nerve stimulation on venous vascular reactivity
Transcutaneous electrical nerve stimulation (TENS) is a type of therapy used primarily for analgesia, but also presents changes in the cardiovascular system responses; its effects are dependent upon application parameters. Alterations to the cardiovascular system suggest that TENS may modify venous vascular response. The objective of this study was to evalua

12. Gender differences in microcirculation: Observation using the hamster cheek pouch
OBJECTIVES: Estrogen has been shown to play an important protective role in non-reproductive systems, such as the cardiovascular system. Our aim was to observe gender differences in vivo with regard to the increase in macromolecular permeability and leukocyte-endothelium interaction induced by ischemia/reperfusion as well as in microvascular reactivity to v
