The Six Pillars of Lifestyle Medicine in Managing Noncommunicable Diseases - The Gaps in Current Guidelines. / Os Seis Pilares da Medicina do Estilo de Vida no Manejo de Doenças Não Transmissíveis ­ As Lacunas nas Diretrizes Atuais.

BACKGROUND: Noncommunicable diseases (NCDs), also known as chronic diseases that are long-lasting, are considered the major cause of death and disability worldwide, and the six pillars of lifestyle medicine (nutrition, exercise, toxic control, stress management, restorative sleep, and social connection) play an important role in a holistic management of their prevention and treatment. In addition, medical guidelines are the most accepted documents with recommendations to manage NCDs. OBJECTIVE: The present study aims to analyze the lack of lifestyle pillars concerning the major Brazilian medical guidelines for NCDs and identify evidence in the literature that could justify their inclusion in the documents. METHOD: Brazilian guidelines were selected according to the most relevant causes of death in Brazil, given by the Mortality Information System, published by the Brazilian Ministry of Health in 2019. Journals were screened in the PUBMED library according to the disease and non-mentioned pillars of lifestyle. RESULTS: Relevant causes of deaths in Brazil are acute myocardial infarction (AMI), diabetes mellitus (DM), and chronic obstructive pulmonary diseases (COPD). Six guidelines related to these NCDs were identified, and all address aspects of lifestyle, but only one, regarding cardiovascular prevention, highlights all six pillars. Despite this, a literature search involving over 50 articles showed that there is evidence that all the pillars can help control each of these NCDs. CONCLUSION: Rarely are the six pillars of lifestyle contemplated in Brazilian guidelines for AMI, DM, and COPD. The literature review identified evidence of all lifestyle pillars to offer a holistic approach for the management and prevention of NCDs.

FUNDAMENTO: As doenças crônicas não transmissíveis (DCNT), também conhecidas como doenças crônicas de longa duração, são consideradas a principal causa de morte e incapacidade em todo o mundo, e os seis pilares da medicina do estilo de vida (nutrição, exercício, controle de tóxicos, manejo do estresse, saúde do sono e conexão social) desempenham um papel importante na gestão holística da sua prevenção e tratamento. Além disso, as diretrizes médicas são os documentos mais aceitos com recomendações para o manejo das DCNT. OBJETIVO: O presente estudo tem como objetivo analisar a ausência de pilares de estilo de vida nas principais diretrizes médicas brasileiras sobre as DCNT e identificar evidências na literatura que possam justificar sua inclusão nos documentos. MÉTODO: As diretrizes brasileiras foram selecionadas de acordo com as causas de morte mais relevantes no Brasil, informadas pelo Sistema de Informações sobre Mortalidade publicado pelo Ministério da Saúde em 2019. Os periódicos foram selecionados na biblioteca PUBMED de acordo com a doença e os pilares do estilo de vida não mencionados. RESULTADOS: Causas relevantes de mortes no Brasil são o infarto agudo do miocárdio (IAM), o diabetes mellitus (DM) e as doenças pulmonares obstrutivas crônicas (DPOC). Foram identificadas seis diretrizes relacionadas a essas DCNT e todas abordam aspectos do estilo de vida, mas apenas uma, referente à prevenção cardiovascular, destaca todos os seis pilares. Apesar disso, uma pesquisa bibliográfica envolvendo mais de 50 artigos mostrou que há evidências de que todos os pilares podem ajudar no controle de cada uma dessas DCNT. CONCLUSÃO: Raramente os seis pilares do estilo de vida são contemplados nas diretrizes brasileiras para IAM, DM e DPOC. A revisão da literatura identificou evidências de todos os pilares do estilo de vida para oferecer uma abordagem holística para a gestão e prevenção das DCNT.

Biofertilizers from wastewater treatment as a potential source of mineral nutrients for growth of amaranth plants.

Exploring alternative fertilizers is crucial in agriculture due to the cost and environmental impact of inorganic options. This study investigated the potential of sewage-derived biofertilizers on the growth and physiology of Amaranthus cruentus plants. Various treatments were compared, including control treatments with inorganic fertilizer and treatments with biofertilizers composed of microalgae, biosolids and reclaimed water. The following traits were investigated: photosynthetic pigments, gas exchange, growth, and leaf nutrient concentrations. The results showed that the concentrations of N, P, Cu, Fe Zn and Na nutrients, in the dry microalgae and biosolids, were quite high for the needs of the plants. The wet microalgae presented high concentration of Cu, Fe and Zn nutrients while reclaimed water contained high concentration of N, K, Ca and S. Na and Zn nutrients increased in the leaf of plants treated with dry microalgae and biosolid, respectively. At the beginning of the flowering phase, total chlorophyll and carotenoids contents were lower for plants grown with wet microalgae while for plants grown with higher doses of biosolid or reclaimed water total chlorophyll was increased, and carotenoids were not affected. Lower photosynthetic pigments under wet microalgae resulted in lower photosynthetic rates. On the other hand, amendments with dry microalgae and biosolid increased photosynthetic rates with the biosolid being the most effective. Higher applications of biosolid, wet and dry microalgae produced a considerable increase in shoot biomass of amaranth, with the dry microalgae being the most effective. Additionally, reclaimed water obtained after tertiary treatment of sewage with microalgae and biosolids applied alone showed promising effects on plant growth. Overall, these findings suggest that organic fertilizers derived from sewage treatment have the potential to enhance plant growth and contribute to sustainable agricultural practices.

Bridging the Gap: Exploring the Preclinical Potential of Pereskia grandifolia in Metabolic-Associated Fatty Liver Disease.

Metabolic-associated fatty liver disease (MAFLD) is a complex condition characterized by steatosis and metabolic disturbances. Risk factors such as diabetes, cigarette smoking, and dyslipidaemia contribute to its development and progression. Effective and safe therapies for MAFLD are urgently needed. Pereskia grandifolia has shown potential as an alternative treatment, but its effectiveness against liver disease remains unexplored. This research aims to determine the hepatoprotective properties of P. grandifolia using a model of MAFLD. The study was carried out through various phases to assess the safety and efficacy of the ethanol-soluble fraction of P. grandifolia. Initially, an in vitro assay was performed to assess cell viability. This was followed by an acute toxicity test conducted in rats to determine the safety profile of the extract. Subsequently, the anti-inflammatory properties of P. grandifolia were examined in macrophages. For the MAFLD study, diabetic Wistar rats were made diabetic and exposed to a high fat diet and cigarette smoke, for 4 weeks. During the last 2 weeks, the rats were orally given either the vehicle (negative control group; C-), P. grandifolia (30, 100, and 300 mg/kg), or insulin in addition to simvastatin. A basal group of rats not exposed to these risk factors was also assessed. Blood samples were collected to measure cholesterol, triglycerides, glucose, ALT, and AST levels. Liver was assessed for lipid and oxidative markers, and liver histopathology was examined. P. grandifolia showed no signs of toxicity. It demonstrated anti-inflammatory effects by inhibiting phagocytosis and macrophage spreading. The MAFLD model induced liver abnormalities, including increased AST, ALT, disrupted lipid profile, oxidative stress, and significant hepatic damage. However, P. grandifolia effectively reversed these changes, highlighting its potential as a therapeutic agent. These findings emphasize the significance of P. grandifolia in mitigating hepatic consequences associated with various risk factors.

Cardioprotective effects of Baccharis trimera (Less) DC in a rodent model of hookah, alcohol, and energy drink exposure / Efectos cardioprotectores de Baccharis trimera (Less) DC en un modelo de roedor de exposición a narguile, alcohol y bebidas energéticas

This study proposes an unpreceded model of cardiovascular disease by combining alcohol and energy drink intake with hookah smoking to investigate the cardiovascular effects of Baccharis trimera (Less.) DC., a medicinal plant used to treat dyslipidemia. For 10 weeks, Wistar rats (n=8) received alcohol (10% ad libitum) and energy drink (2 mL/kg) and/or were exposed to hookah smoke (1 hour/day). In the last 4 weeks, the animals received daily treatment with vehicle (filtered water) or ethanol soluble fraction of B. trimera (30, 100 and 300 mg/kg). Electrocardiography was performed. Systolic, diastolic, and mean blood pressure, heart rate, and plasmatic cholesterol, triglycerides, urea, creatine, aspartate, and alanine aminotransferase levels were determinate. The heart, aorta, and kidneys were histopathological evaluated. In isolation the risk factors altered all the evaluated parameters and when the risk factors were associated, a synergistic effect was observed. Treatment with B. trimera reversed these cardiovascular changes.

Este estudio propone un modelo sin precedentes de enfermedad cardiovascular mediante la combinación de la ingesta de bebidas energéticas y alcohol con fumar narguile para investigar los efectos cardiovasculares de Baccharis trimera (Less.) DC., una planta utilizada para tratar la dislipidemia. Durante 10 semanas, las ratas Wistar recibieron alcohol (10%) y bebida energética y/o fueron expuestas al humo de narguile. En las últimas 4 semanas, los animales recibieron tratamiento con vehículo, fracción soluble en etanol de B. trimera (30, 100, 300 mg/kg). Se realizó electrocardiografía. Se determinaron los niveles de presión arterial sistólica, diastólica y media, frecuencia cardíaca, colesterol plasmático, triglicéridos, aspartato y alanina aminotransferasa, urea y creatina. El corazón, la aorta y los riñones fueron evaluados histopatológicamente. De forma aislada los factores de riesgo alteraron todos los parámetros evaluados y cuando se asociaron los factores se observó un efecto sinérgico. El tratamiento con B. trimera revirtió estos cardiovasculares cambios.

Impact of different activation wavefronts on ischemic myocardial scar electrophysiological properties during high-density ventricular tachycardia mapping and ablation.

INTRODUCTION: Scar-related ventricular tachycardia (VT) usually results from an underlying reentrant circuit facilitated by anatomical and functional barriers. The later are sensitive to the direction of ventricular activation wavefronts. We aim to evaluate the impact of different ventricular activation wavefronts on the functional electrophysiological properties of myocardial tissue. METHODS: Patients with ischemic heart disease referred for VT ablation underwent high-density mapping using Carto®3 (Biosense Webster). Maps were generated during sinus rhythm, right and left ventricular pacing, and analyzed using a new late potential map software, which allows to assess local conduction velocities and facilitates the delineation of intra-scar conduction corridors (ISCC); and for all stable VTs. RESULTS: In 16 patients, 31 high-resolution substrate maps from different ventricular activation wavefronts and 7 VT activation maps were obtained. Local abnormal ventricular activities (LAVAs) were found in VT isthmus, but also in noncritical areas. The VT isthmus was localized in areas of LAVAs overlapping surface between the different activation wavefronts. The deceleration zone location differed depending on activation wavefronts. Sixty-six percent of ISCCs were similarly identified in all activating wavefronts, but the one acting as VT isthmus was simultaneously identified in all activation wavefronts in all cases. CONCLUSION: Functional based substrate mapping may improve the specificity to localize the most arrhythmogenic regions within the scar, making the use of different activation wavefronts unnecessary in most cases.

Docetaxel Loaded in Copaiba Oil-Nanostructured Lipid Carriers as a Promising DDS for Breast Cancer Treatment.

Breast cancer is the neoplasia of highest incidence in women worldwide. Docetaxel (DTX), a taxoid used to treat breast cancer, is a BCS-class-IV compound (low oral bioavailability, solubility and intestinal permeability). Nanotechnological strategies can improve chemotherapy effectiveness by promoting sustained release and reducing systemic toxicity. Nanostructured lipid carriers (NLC) encapsulate hydrophobic drugs in their blend-of-lipids matrix, and imperfections prevent drug expulsion during storage. This work describes the preparation, by design of experiments (23 factorial design) of a novel NLC formulation containing copaiba oil (CO) as a functional excipient. The optimized formulation (NLCDTX) showed approximately 100% DTX encapsulation efficiency and was characterized by different techniques (DLS, NTA, TEM/FE-SEM, DSC and XRD) and was stable for 12 months of storage, at 25 °C. Incorporation into the NLC prolonged drug release for 54 h, compared to commercial DTX (10 h). In vitro cytotoxicity tests revealed the antiproliferative effect of CO and NLCDTX, by reducing the cell viability of breast cancer (4T1/MCF-7) and healthy (NIH-3T3) cells more than commercial DTX. NLCDTX thus emerges as a promising drug delivery system of remarkable anticancer effect, (strengthened by CO) and sustained release that, in clinics, may decrease systemic toxicity at lower DTX doses.

Chenopodium ambrosioides conhecida como mastruço, é utilizado na medicina tradicional para tratamento de ascaridíase; controle de artrópodes e pragas domésticas; inibição do desenvolvimento de fungos do solo e de insetos, tratamento de lesões cutâneas e alívio da dor de barriga e gripe. O objetivo do presente trabalho constituiu na avaliação do teor extrativo do óleo essencial de Chenopodium ambrosioides L. cultivado no Horto Medicinal da Universidade Paranaense (Umuarama-PR), durante um ano, no período de setembro de 2006 a agosto de 2007. A metodologia foi realizada através da coleta do material vegetal para obtenção do óleo pelo processo de hidrodestilação dos frutos frescos de mastruço. O rendimento do óleo foi calculado a partir da massa dos frutos frescos pela massa do óleo essencial obtido. Também foram avaliados os parâmetros de temperatura e índices pluviométricos aferidos diariamente. Os resultados demonstram um maior rendimento do óleo no período em que as temperaturas e índices pluviométricos estavam mais elevados (1,096 % na primavera e 0,998 % no verão); já em meses com temperaturas mais amenas e/ou secos o rendimento de óleo essencial apresentou considerável redução (0,774 % no outono e 0,819 % no inverno). Isto indica que o aumento e diminuição da produção de óleo essencial pela planta é influenciada pelos fatores climáticos, mostrando a importância deste estudo com a finalidade de padronização da época de colheita para maior rendimento do óleo e consequente aplicação em produtos cosméticos e farmacêuticos.

Avaliação do potencial de melhoria de Baccharis trimeraem um modelo experimental de doença pulmonar / On the ameliorative potential of Baccharis trimera in an experimental model of pulmonary disease

Diabetes mellitus, tabagismo e dislipidemia são mais prevalentes em pacientes com doença pulmonar obstrutiva crônica (DPOC), a quarta causa de mortalidade no mundo. Este estudo empregou um modelo de doença pulmonar em ratos Wistar que incorporou esses três fatores de risco e investigou os efeitos da Baccharis trimera, uma planta medicinal amplamente utilizada, uma vez que nenhum estudo avaliou seus efeitos pulmonares. Os ratos diabéticos e dislipidêmicos foram expostos à fumaça de cigarro por 4 semanas e tratados com veículo (grupo C-), extrato de B. trimera (HEBT), ou sinvastatina+insulina, por 2 semanas. O lavado broncoalveolar foi realizado para avaliar a inflamação. Os pulmões foram coletados para análises histopatológicas e do estado redox. Foi observada diminuição do peso corporal, aumento do estresse oxidativo, inflamação e alterações histopatológicas no grupo C-. HEBT reverteu essas alterações e apresentou efeito antiinflamatório moderado. O tratamento com HEBT apresentou efeitos promissores para a DPOC.

Diabetes mellitus, smoking, and dyslipidemia are more prevalent in patients with chronic obstructive pulmonary disease (COPD), the fourth leading cause of mortality worldwide. This study employed a model of lung disease in Wistar rats that incorporated these three risk factors, and investigated the effects of Baccharis trimera, a widely used medicinal plant, since no previous studies have evaluated its pulmonary effects. The diabetic and dyslipidemic rats were exposed to smoke for 4 weeks and treated with vehicle (C- group), an extract of B. trimera (HEBT), or simvastatin+insulin, for 2 weeks. The bronchoalveolar lavage was performed to evaluate inflammation. The lungs were collected for histopathological and redox state analyses. A decrease in body weight, an increase in oxidative stress, inflammation, and histopathological changes were observed in C- group. HEBT reversed these alterations and had a moderate antiinflammatory effect. Treatment with HEBT present promising effects for COPD.

Croton urucurana Baill. Ameliorates Metabolic Associated Fatty Liver Disease in Rats.

Background: Metabolic associated fatty liver disease (MAFLD) affects a quarter of the worldwide population, but no drug therapies have yet been developed. Croton urucurana Baill. (Euphorbiaceae) is a medicinal species, that is, widely distributed in Brazil. It is used in popular medicine to treat gastrointestinal, cardiovascular, and endocrine system diseases. However, its hepatoprotective and lipid-lowering effects have not yet been scientifically investigated. Aim of the study: The present study investigated the effects of an extract of C. urucurana in a rat model of MAFLD that was associated with multiple risk factors, including hypertension, smoking, and dyslipidemia. Material and Methods: The phytochemical composition of C. urucurana was evaluated by liquid chromatography-mass spectrometry. Spontaneously hypertensive rats received a 0.5% cholesterol-enriched diet and were exposed to cigarette smoke (9 cigarettes/day for 10 weeks). During the last 5 weeks, the animals were orally treated with vehicle (negative control [C-] group), C. urucurana extract (30, 100, and 300 mg/kg), or simvastatin + enalapril (two standard reference drugs that are commonly used to treat dyslipidemia and hypertension, respectively). One group of rats that were not exposed to these risk factors was also evaluated (basal group). Blood was collected for the analysis of cholesterol, triglyceride, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels. The liver and feces were collected for lipid quantification. The liver was also processed for antioxidant and histopathological analysis. Results: The main constituents of the C. urucurana extract were flavonoids, glycosides, and alkaloids. The model successfully induced MAFLD, reflected by increases in AST and ALT levels, and induced oxidative stress in the C- group. Treatment with the C. urucurana extract (300 mg/kg) and simvastatin + enalapril decreased plasma and hepatic lipid levels. In contrast to simvastatin + enalapril treatment, C. urucurana reduced AST and ALT levels. Massive lesions were observed in the liver in the C- group, which were reversed by treatment with the C. urucurana extract (300 mg/kg). Conclusion: C. urucurana extract exerted promising hepatoprotective and lipid-lowering effects in a preclinical rat model of MAFLD.

Economic, social, and environmental assessment of farming Nile tilapia in net-cages in a reservoir in hot semi-arid region during an extended drought event.

Water reservoirs have been constructed in hot semi-arid regions, which may be used to produce fish. The present study described major features of the economic, social, and environmental characteristics of a net-cage Nile tilapia production system, stocked with 100 and 120 fish/m3, implemented in a reservoir in the hot semi-arid region of Brazil during an extended drought event. The production cycle was reduced from 6-8 to 4 months because of the lack of water in the reservoir. This resulted in the harvest of small fish weighting ~300-350 g that reached a low value in the market. As a consequence, indicators of financial feasibility showed low values, which were not attractive for entrepreneurs. Nevertheless, for both stocking densities, the monthly income was about US$ 1,500.00, which is 5-fold the minimum wage in the region. In general, the activity has a positive social impact, despite the low contribution to development of the local economy and food security because most supply came from outside and fish were sold to distant regions. Various age and ethnic groups were represented among the employees, but the enterprise was operated only by men. Phosphorus accumulations in the reservoir were 2.1 and 2.0 kg/t of fish produced and particulate material accumulations of 110 and 100 kg/t of fish production for 125 fish/m3 and 100 fish/m3, respectively. The study indicated that the Nile tilapia culture in hot semi-arid region is strongly affected by long drought events and adaptations in the planning and management should be done when implementing the systems. However, it seems that the activity has some resilience to still provide food, generate wealth, and promote social development for local population with low environmental impact.

Bioactive compounds with antifungal activity against pathogens isolated from pregnant woman: Gallesia integrifolia (garlic wood) is a promising treatment for vulvovaginal candidiasis.

ETHNOPHARMACOLOGICAL RELEVANCE: The leaves, bark, and roots of Gallesia integrifolia are consumed in folk medicine through infusion, decoction, and topical preparation by crushing because of its pharmacological properties in several peripheral system disorders, including microbial infections. The presence of various molecules in different parts of the plant likely confers this species' fungicidal action, but scientific evidence is lacking. Vulvovaginal candidiasis mainly affects women of reproductive age. When left untreated, it can cause pregnancy complications. Currently available antifungals often cause undesirable side effects. New alternative therapeutic strategies based on medicinal plants have been proposed. AIM: To investigate the antifungal activity of G. integrifolia against vulvovaginal candidiasis secretion in pregnant women. MATERIALS AND METHODS: Antifungal activity was determined by the minimum inhibitory concentration (MIC), determined by broth microdilution method using Candida spp (NEWP1210), C. albicans (CCCD-CC001), C. tropicalis (CCCD-CC002) standard and clinical isolates from pregnant women with vulvovaginal candidiasis. Nystatin and fluconazole were used as positive controls. The chemical composition of essential oils that were extracted from leaves, flowers, and fruits of G. integrifolia was determined by gas chromatography coupled to mass spectrometry. Reverse docking was used to suggest a possible target in Candida. Conventional docking was used to identify the most probable compound that inhibits fungal growth. RESULTS: A total of 24 compounds were identified, accounting for ∼99% of volatile constituents in the essential oils. Leaves of G. integrifolia contained 3,5-dithiahexanol-5,5-dioxide (40.93%), flowers contained methionine ethyl ester (46.78%), and fruits contained 2,8-dithianonane (54.01%) as the most abundant compounds. The MICs of essential oils of leaves, flowers, and fruits of G. integrifolia against standard strains of Candida spp, C. albicans, and C. tropicalis ranged from 13.01 to 625.00 µg/mL. The essential oil of flowers more effectively inhibited Candida spp. Essential oils of leaves and flowers were similar to fluconazole against C. albicans. Essential oils of flowers and fruits were similar to fluconazole against C. tropocalis. In Candida yeast species that were isolated from vaginal secretion samples from pregnant patients, the MICs of leaves and flowers ranged from 52.08 to 5000.00 µg/mL. The essential oil of leaves (277.77 µg/mL) was the most active against C. albicans. No significant differences were found between the essential oils of leaves and flowers against C. glabrata. Docking simulations suggested that phytol in leaves and flowers was responsible for the antimicrobial effect. CONCLUSION: The present results suggest the potential therapeutic use of G. integrifolia, especially its leaves and flowers, against Candida and vulvovaginal candidiasis.

Effect of the addition of Euterpe oleracea Mart. extract on the properties of starch-based sachets and the impact on the shelf-life of olive oil.

This study aimed to produce and characterized active biodegradable packages by extrusion of cassava starch, biodegradable polyester, plasticizer, and acai extract (EA 0, 1, 2, 3 and 4%) and to evaluate its effects on extra virgin olive oil (EVOO) for 120 days. All analyses were performed at the beginning (day 0) and the end of the experiment (day 120). The oil was characterized for acidity index (IA), peroxide index (IP), thiobarbituric acid reactive substances (TBARS), conjugated dienes (CD), phenolic compounds (PC) and color parameters. The incorporation of EA at the initial time caused increased thickness, mechanical properties, solubility in water and oil in all formulations. The some values of properties increased or decreased, due to the interaction of the stored product and packaging. At the end of the storage period, the values of IA and IP were below the limits established by current legislation.

(sinônimo Triticum vulgare) em modelo de pele humana nativa / Comparative study to evaluate the wound healing efficacy of topical formulations containing Triticum aestivum L. (Triticum vulgare) in a native human skin model

Introdução: extratos vegetais e ativos derivados de plantas tem sido desenvolvidos com o objetivo de melhorar e potencializar o processo de cicatrização cutânea, dentre eles, o Triticum aestivum L. (sinônimo Triticum vulgare). Objetivo: avaliar o efeito do extrato de grão inteiro (EGTA-PR) e extrato aquoso (EATA-FI) de Triticum aestivum L. na cicatrização cutânea em pele humana ex vivo. Métodos: fragmentos de pele obtidos de cirurgia plástica eletiva foram submetidos a lesões teciduais e tratados com os extratos durante oito dias para avaliação histológica da reepitelização e marcação proteica do fator de crescimento epidérmico (EGF). Resultados: EGTA-PR e EATA-FI aceleraram o processo de reepitelização em cultura de pele humana submetida a lesão tecidual. Adicionalmente, foi observado um aumento da marcação proteica de EGF após o tratamento com EGTA-PR. Conclusão: EGTA-PR apresentou um melhor desempenho na reepitelização quando comparado ao EATA-FI, pois apresentou uma maior marcação proteica para EGF em cultura de pele humana. Da mesma forma, os resultados histológicos mostraram que a redensificação dérmica obtida com o EGTA-PR foi visualmente superior à observada com EATA-FI. Os resultados obtidos são promissores e corroboram as diversas ações biológicas já reportadas na literatura para extrato de Triticum aestivum L. nas etapas da cicatrização tecidual.

Introduction: Plant extracts and actives derived from plants were developed to improve and enhance the skin healing process including Triticum aestivum L. (Triticum vulgare). Purpose: To evaluate the effect of whole grain extract (EGTA-PR) and aqueous extract (EATA-FI) of Triticum aestivum L., on ex vivo skin healing. Methods: Skin fragments obtained from elective plastic surgery were subjected to tissue damage and treated with extracts for eight days for histological evaluation of re-epithelialization and immunofluorescence for epidermal growth factor (EGF). Results: EGTA-PR and EATA-FI accelerated the re-epithelialization process in human skin culture submitted to tissue injury. Additionally, we observed increased EGF protein labeling after treatment with EGTA-PR. Conclusion: EGTA-PR showed a better performance in re-epithelialization when compared to EATA-FI, as it presented a higher protein labeling for EGF in human skin culture. Likewise, the histological results showed that the dermal redensification obtained with EGTA-PR was visually superior to that observed with EATA-FI. The results obtained are promising and corroborate the several biological actions already reported in the literature for Triticum aestivum L. extract in tissue healing stages

Multiple Risk Factors for Heart Disease: A Challenge to the Ethnopharmacological Use of Croton urucurana Baill.

Croton urucurana Baill. is a native Brazilian tree, popularly known as "sangra-d'água" or "sangue-de-dragão," based on the red resinous sap of the trunk. Its use has been transmitted through generations based on popular tradition that attributes analgesic, anti-inflammatory, and cardioprotective properties to the tree. However, its cardioprotective effects have not yet been scientifically investigated. Thus, the present study investigated the pharmacological response to an ethanol-soluble fraction from the leaves of C. urucurana in Wistar rats exposed to smoking and dyslipidemia, two important cardiovascular risk factors. The extract was evaluated by high-performance liquid chromatography. Wistar rats received a 0.5% cholesterol-enriched diet and were exposed to cigarette smoke (9 cigarettes/day for 10 weeks). During the last 5 weeks, the animals were orally treated with vehicle (negative control group), C. urucurana extract (30, 100, and 300 mg/kg), or simvastatin (2.5 mg/kg) + enalapril (15 mg/kg). One group of rats that was not exposed to these risk factors was also evaluated (basal group). Electrocardiograms and systolic, diastolic, and mean blood pressure were measured. Blood was collected to measure total cholesterol, triglycerides, urea, and creatinine. The heart and kidneys were collected and processed for oxidative status and histopathological evaluation. The phytochemical analysis revealed different classes of flavonoids and condensed tannins. The model induced dyslipidemia and cardiac and renal oxidative stress and increased levels of urea and creatinine in the negative control group. Treatment with the C. urucurana extract (300 mg/kg) and simvastatin + enalapril decreased cholesterol and triglyceride levels. In contrast to simvastatin + enalapril treatment, the C. urucurana extract exerted cardiac and renal antioxidant effects. No alterations of electrocardiograms, blood pressure, or histopathology were observed between groups. These findings indicate that C. urucurana exerts lipid-lowering, renal, and cardioprotective effects against oxidative stress in a preclinical model of multiple risk factors for heart disease.

Ochratoxin a levels in fermented specialty coffees from Caparaó, Brazil: Is it a cause of concern for coffee drinkers?

Although postharvest coffee fruit fermentation can improve coffee flavour and quality, the mycotoxin ochratoxin A (OTA) can also be a result of microbiological activity, albeit in the later drying step of coffee processing. To evaluate the possible occurrence of OTA contamination in postharvest fruit fermentation, fourteen coffees that entailed two different postharvest fruit fermentation times were evaluated. These coffees originated in the surroundings of the village of Pedra Menina in the qualified Denomination of Origin and coffee producer region of Caparaó on the border between Minas Gerais and Espírito Santo states in Brazil. All coffees were classified according to the Specialty Coffee Association (SCA) protocol and 12 achieved specialty level. OTA was determined in all 14 coffees using immunoaffinity for sample clean-up and high-performance liquid chromatography with fluorescence detection for quantification. One sample presented an OTA concentration of 0.75 µg kg-1 and two samples showed OTA concentrations of 0.87 µg kg-1. The other samples had concentrations of OTA below the limit of quantification obtained in this work (0.64 µg kg-1). Thus, all samples showed OTA concentrations far below the most stringent maximum residue limit (MRL) of 5 µg kg-1 established for roasted coffees by European legislation. These low levels were similar to most of the previous results for Brazilian coffees listed and tabled in this work. This comparison showed that OTA contamination due to this kind of postharvest process - fruit fermentation - should not be a concern for producers and consumers of these fermented coffees.

Traditional plants with antioxidant properties in clinical trials-A systematic review.

There is a trend toward the use of natural substances present in plants and vegetables. In general, foods rich in antioxidants are complex matrices; therefore, understanding its absorption effects is extremely relevant to know its bioactive potential. Thus, this systematic review focused on clinical trials involving plants (or compounds) registered on the National List of Medicinal Plants of Interest to the Unified Health System (RENISUS) with antioxidant properties. Following the reporting guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyzes studies of interest indexed in the PubMed and ClinicalTrials.gov databases were analyzed. Of the 59 clinical trials found, Allium sativum and Curcuma longa are the plant species with the highest percentage of clinical research. Prevention/attenuation of oxidative stress was one of the main antioxidant mechanisms indicated in the studies. The most tested compounds of the RENISUS plants in clinical trials were curcumin and soy isoflavone. In this review, we selected studies in advanced stages that highlight plants' value in optimizing antioxidant status; however, even with high-quality studies, it is not prudent to overstate the clinical efficacy of these plants.

Hepato- and cardioprotective effects of Baccharis trimera (Less.) DC. against multiple risk factors for chronic noncommunicable diseases.

Cardiovascular diseases are associated with high morbidity and mortality worldwide and have several risk factors, including dyslipidemia, smoking, and hypertension. Studies have evaluated isolated risk factors in experimental models of cardiovascular disease, but few preclinical studies have assessed associations between multiple risk factors. In the present study, hypertensive Wistar rats (Goldblatt 2K1C model) received a 0.5% cholesterol diet and were exposed to tobacco smoke for 8 weeks. During the last 4 weeks, the animals were treated with vehicle, an ethanol-soluble fraction of B. trimera (30, 100, and 300 mg/kg), or simvastatin + enalapril. A group of normotensive, non-dyslipidemic, and non-smoking rats was treated with vehicle. The levels of aspartate aminotransferase, alanine aminotransferase, urea, creatinine, and hepatic and fecal lipids, blood pressure, and mesenteric arterial bed reactivity were evaluated. Cardiac, hepatic, and renal histopathology and tecidual redox state were also investigated. Untreated animals exhibited significant changes in blood pressure, lipid profile, and biomarkers of heart, liver, and kidney damage. Treatment with B. trimera reversed these changes, with effects that were similar to simvastatin + enalapril. These findings suggest that B. trimera may be promising for the treatment of cardiovascular and hepatic disorders, especially disorders that are associated with multiple risk factors.
