1. Diesel-Like Biofuels Production Using Fatty Waste
According to the waste-to-energy (WTE) valorization and circular economy principles, the use of waste oil and grease (WOG) for obtaining biofuels shows the tendency towards sustainability, makes the interest in green chemistry, and the development of environmentally friendly processes grow. Three different fatty wastes (from the fat trap of a sewage station,

2. Consumo de Oxigênio e Aptidão Cardiorrespiratória | Diferença entre Idade Cronológica e Biológica
Biodiesel made from oils is rich in polyunsaturated fatty acids methyl esters, and, consequently, presents high tendency to oxidize. Biodiesel made from fats, on the other hand, is mainly comprised by saturated chains. Although it is highly stable, they easily crystalize at low temperatures. Blends from both can exhibit optimized properties. In this work, ox

4. High-Lard and High-Cholesterol Diet, but not High-Lard Diet, Leads to Metabolic Disorders in a Modified Dyslipidemia Model
Resumo Fundamento: Tendo em vista o aumento da prevalência global de doenças cardiovasculares e hepáticas, o conteúdo lipídico da dieta e sua relação com o acúmulo de gordura nos hepatócitos têm sido investigados como fatores-chave na prevenção dessas doenças. Objetivo: Avaliar os efeitos metabólicos de uma dieta rica em banha suplementada co

5. High-fat diet and streptozotocin in the induction of type 2 diabetes mellitus: a new proposal
Our objective was to establish a diabetes mellitus type 2 (DM2) model in rats using a high-fat diet and streptozotocin (HF-STZ). Male Wistar rats (240-250g) were divided into a control group (commercial feed), and HF-STZ group, (66.5%-commercial feed, 13.5%-lard, and 20%-sugar). STZ (40mg/kg i.p.) or vehicle was administered on the 13th day. An oral glucose

6. Metabolic and Testicular Effects of the Long-Term Administration of Different High-Fat Diets in Adult Rats
ABSTRACT Purpose: To evaluate the effects of different high-fat diets on body mass, carbohydrate metabolism and testicular morphology in rats seven months old.
Materials and Methods: Male Wistar rats were divided into four groups: SC (standard chow), HF-S (high fat diet rich in saturated fatt

7. Correlation Between the Composition and Flash Point of Diesel-Biodiesel Blends
Methyl ester biodiesels from vegetable oils, including soy, corn, canola and sunflower, and from swine lard, were prepared. They were mixed with mineral diesel to produce blends from 5% v/v to 50% v/v of biodiesel, i.e., B5, B10, B20 and B50. The flash points of these mixtures, the pure diesel (B0) and the pure biodiesel (B100) were determined. In all cases,

8. Lard and/or canola oil-rich diets induce penile morphological alterations in a rat model
PURPOSE: To investigate the effect of dietary lipid quantity and/or quality on penis morphology in adult rats. METHODS: Thirty-eight male Wistar rats were divided into 4 groups: normal lipid diet (NL), high-fat diet rich in saturated fatty acids (HF-S), high-fat diet rich in polyunsaturated fatty acids (HF-P), and high-fat diet rich in saturated and polyuns

9. Antioxidant and stabilization activity of a quercetin-containing flavonoid extract obtained from Bulgarian Sophora japonica L.
This work aimed to study the antioxidant activity of a quercetin-containing flavonoid extract (FQЕ) obtained from Sophora japonica L. flower buds rich in quercetin (91.6%). Radical scavenging activity was analyzed towards the synthetic radicals DPPH• and ABTS•+ and antioxidant activity was evaluated applying the method of oxygen consumption in a model s

10. Obtenção de biodiesel por transesterificação em dois estágios e sua caracterização por cromatografia gasosa: óleos e gorduras em laboratório de química orgânica
Methanolic transesterification of oils and fats was carried out in a two steps procedure, under basic and acidic catalysis. Palm, soybean, canola, corn, rice, grapeseed, sunflower, peanut, pequi and olive oils, besides tallow and lard were used as feedstock. Specific gravity, relative viscosity, thin layer chromatography and gas chromatography were used to c

11. A expressão e atividade da NAD(P)H oxidase em ilhotas pancreáticas de ratos tratados com dieta hiperlipídica. / NAD(P)H oxidase expression and activity in pancreatic islets from rats treated with high fat diet.
Feeding animals with high fat diet containing lard causes obesity, insulin resistance and dysfunction of pancreatic beta cells. High fat diet induces oxidative stress and modulates NAD(P)H oxidase expression and activity in many tissues. This enzyme may be involved in many pathophysiological processes. The objective of this study was to evaluate the action o

12. BIODIESEL A PARTIR DE ÓLEOS DE ALTA ACIDEZ: Desenvolvimento de um processo catalítico homogêneo
The present work aims at developing a process for the production of biodiesel from oils of high acidity, using a process in two steps in homogeneous catalysis. The first is the reaction of ethyl esterification of free fatty acid, catalyzed by H2SO4, occurring on triglycerides and the second is the transesterification of residual triglycerides, from the first
