1. After Thirty Years, We Still Cannot Understand Why Methylene Blue is not a Reference to Treat Vasoplegic Syndrome in Cardiac Surgery
Abstract Vasoplegic syndrome (VS) comprises a constellation of concurrent signs and symptoms: hypotension, high cardiac index, low systemic vascular resistance, low filling pressures, the tendency to occur diffuse bleeding, and sustained hypotension. All of these parameters may persist even despite the use of high doses of vasoconstrictor amines. VS arises f

2. Metabolic syndrome components are associated with oxidative stress in overweight and obese patients
ABSTRACT Objective: The aim of this study is to evaluate the influence of the body mass index (BMI) and the metabolic syndrome (MetS) parameters on oxidative and nitrosative stress in overweight and obese subjects. Subjects and methods: Individuals were divided into three groups: the control group (G1, n = 131) with a BMI between 20 and 24.9 kg/m2, the ove

3. The in vivo effect of L-arginine on skin elasticity in mice
ABSTRACT The human skin aging process is a complex mechanism that can be induced both by intrinsic and extrinsic factors. Observations include a decrease in the biosynthetic and proliferative capacity of cells, increased expression of matrix metalloproteinases, reduction in collagen type I expression, and the progressive disappearance of elastic tissue in th

4. Activity of Brazilian propolis against Aeromonas hydrophila and its effect on Nile tilapia growth, hematological and non-specific immune response under bacterial infection
ABSTRACT The effect of the ethanolic extract of propolis (EEP) on Aeromonas hydrophila was analyzed by determination of minimum inhibitory concentration (MIC). Then, the effects of crude propolis powder (CPP) on growth, hemato-immune parameters of the Nile tilapia, as well as its effects on resistance to A. hydrophila challenge were investigated. The CPP (0.

5. Methylene Blue to Treat Protamine-induced Anaphylaxis Reactions. An Experimental Study in Pigs
ABSTRACT Objective: To examine if methylene blue (MB) can counteract or prevent protamine (P) cardiovascular effects. Methods: The protocol included five heparinized pig groups: Group Sham -without any drug; Group MB - MB 3 mg/kg infusion; Group P - protamine; Group P/MB - MB after protamine; Group MB/P - MB before protamine. Nitric oxide levels were obtai

6. 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

7. Methylmercury inhibits prolactin release in a cell line of pituitary origin
Heavy metals, such as methylmercury, are key environmental pollutants that easily reach human beings by bioaccumulation through the food chain. Several reports have demonstrated that endocrine organs, and especially the pituitary gland, are potential targets for mercury accumulation; however, the effects on the regulation of hormonal release are unclear. It

8. Efeito da resistência de Spodoptera frugiperda (J.E.Smith, 1797) (Lepidoptera: Noctuidae) a lambda-cyhalothrin na interação com o milho geneticamente modificado (MON810) e na resposta imunológica ao parasitismo por Campoletis af / Effect of resistance of Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) to lambda-cyhalothrin on the interaction with genetically modified maize (MON810) and the immune response to parasitization by Campoletis aff. flavicincta (Hymenoptera: Ichneumonidae)
Fitness costs of insect resistance to insecticides can be exploited by integrating other pest control strategies in Integrated Pest Management (IPM) programs. The objective of this research was to evaluate the existence of fitness costs associated with the resistance of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) to the pyrethroid insecticid

9. In vitro study of the effect of a probiotic bacterium Lactobacillus rhamnosus against herpes simplex virus type 1
BACKGROUND: Due to the emergence of drug resistance in herpes simplex virus type 1 (HSV-1), researchers are trying to find other methods for treating herpes simplex virus type 1 infections. Probiotic bacteria are effective in macrophage activation and may have antiviral activities. OBJECTIVE: This study aimed at verifying the direct effect of Lactobacillus r

10. Caracterização da disfunção erétil em camundongos obesos tratados com dieta hiperlipídica / Characterization of erectile dysfunction in obese mice fed a high-fat diet
The prevalence of obesity is increasing every year, and a becoming a major public health problem. Obesity is considered an important risk factor for development of insulin resistance, dyslipidemia, diabetes mellitus type 2 and arterial hypertension. These are risk factors that act synergistically in the development of erectile dysfunction. However, so far fe

11. Efeito de uma fosfolipase A2 básica isolada da peçonha de Bothropoides pauloensis (Bothrops pauloensis) sobre formas promastigota de Leishmania (Leishmania) amazonensis
CHAPTER 2: Leishmaniasis is a group of diseases caused by protozoa of Leishmania genus. The currently available treatment for this disease presents high toxicity and cost, parasite resistance, and difficulties of healing. In this sense, the development of new strategies for treatment of leishmaniasis is indispensable and snake venoms appear as an important n

12. Effects of oral administration of S-nitrosothiols and knectic evaluation of the kinetic propensity and resistance to diet induced obessity / Efeitos da administração orogástrica de s-nitrosotióis e avaliação cinética da propensão e resistência à obsidade induzida por dieta
In the present study, the nitric oxide (NO)-associated physiological actions obtained topically on the gastric mucosa and systemically in oral administrations of two NO donors-S-nitrosothiols (RSNOs), S-nitrosoglutathione (GSNO) and S-nitroso-N-acetylcysteine (SNAC) were investigated in animal models. The topical ex vivo administration of RSNOs solutions on
