1. LENTINULA EDODES POLYSACCHARIDES SUPPRESSED PRO-INFLAMMATORY CYTOKINES EXPRESSION AND COLITIS IN MICE
RESUMO Contexto: Polissacarídeos de cogumelos comestíveis possuem atividades imunomodulatórias, anti-inflamatórias e anti-tumorais. Estudos recentes indicaram que a necroptose desempenha um papel na patogênese de doenças inflamatórias e regula o aumento da expressão de citocinas inflamatórias. Objetivo: Torna-se imprescindível determinar o impa

2. 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

3. Dietary iron chelate for sows and effects on iron supplementation in piglets
Abstract: In order to evaluate iron chelate in diets for sows during gestation and lactation and its effects on iron supplementation for piglets, a total of 50 pregnant sows in the third parity order were distributed according to a randomized block design with two treatments: diet without iron chelate supplementation (n=20); diet supplemented with 0.15% of i

4. HDL-PARTICLES SEPARATION EMPLOYING DIFFERENT PRECIPITATING AGENTS: FUNCTIONAL PROPERTIES OF THE IMPACT OF CHEMICAL PRECIPITATION ON LIPOPROTEIN PARTICLE-SIZE AND PARAOXONASE-1-ACTIVITY
First-generation methods used to quantify HDL-cholesterol have been used for decades. Therefore, first-generation precipitatingreagents still in use, the chemical impact on HDL-particles functionality (structure/activity-relationship) is not well-documented. The study aim was to identify the most efficient precipitating-reagent for lipoprotein separation to

5. Nanostructured polymeric system based of cashew gum for oral admnistration of insulin
ABSTRACT The subcutaneous administration of insulin has been the treatment of millions of diabetics in the world. However, for such via insulin is invasive and not mimics the physiological action causing side effects. The oral route would be the most physiological and comfortable option, but the oral bioavailability of insulin is low by proteolytic activity

6. Inhibitory effect of Lonchocarpus araripensis lectin in rat acute models of inflammation
Abstract: Dalbergieae tribe lectins, possessing binding affinity for galactose and mannose, present inflammatory and nociceptive effects, while those for N-acetylglucosamine are anti-inflammatory. Since the anti-inflammatory effect of the seed lectin of L. araripensis (LAL) had been already demonstrated in mice, this effect was presently evaluated in rat mod

8. Determination of Short Chain Fatty Acids in Mice Feces by Capillary Electrophoresis
Short-chain fatty acids (SCFA) are compounds produced during fermentation of gut microbiota. Acetic, propionic and butyric acids are the most important SCFA produced from non-digestible foods. We developed and validated a rapid and low-cost capillary electrophoretic (CE) method for determination of acetic, propionic and butyric acids in mice feces (100 mg of

9. Effect of vaporized perfluorocarbon on oxidative stress during the cold ischemia phase of lung graft preservation
RESUMO O perfluorocarbono (PFC) líquido tem sido estudado experimentalmente como uma substância adjuvante na preservação de enxertos pulmonares durante o período de isquemia fria. O objetivo deste estudo foi avaliar se o PFC vaporizado (e não instilado) também atuaria como protetor de enxertos pulmonares em diferentes tempos de isquemia fria. Realizam

10. SYNTHESIS AND NUCLEAR MAGNETIC RELAXATION PROPERTIES OF COMPOSITE IRON OXIDE NANOPARTICLES
Superparamagnetic iron oxide nanoparticles are suitable contrast agents for magnetic resonance imaging due to their effect on proton relaxation times, and excellent biocompatibility and biodistribution in tissue. In the present study, a ferrofluid formed by dextran-coated iron oxide nanoparticles was prepared by the coprecipitation method and with subsequent

11. Ethacrynic acid decreases expression of proinflammatory intestinal wall cytokines and ameliorates gastrointestinal stasis in murine postoperative ileus
OBJECTIVES: Several compounds characterized by an olefin linkage conjugated to a carbonyl group have anti-inflammatory properties. The diuretic ethacrynic acid (EA) is a compound of this type. Herein, we tested the hypothesis that ethacrynic acid can modulate the development of ileus after bowel manipulation. METHODS: Groups (n=9) of male C57Bl/6 mice unde

12. Essential oil of Pterodon polygalaeflorus Benth attenuates nociception in mice
Essential oils (EO) are volatile liquids responsible for the aroma of plants. Pterodon polygalaeflorus seeds have received widespread use in folk medicine for the treatment of inflammatory diseases. For this reason and because Pterodon polygalaeflorus seeds have great EO content, which is frequently pharmacologically active, the present study aimed to evalua
