Biotransformed soybean cream as a new nutraceutical for skin care: collagen stimulation in vitro and ex vivo

Treatments that attenuate the effects of hypoestrogenism in menopausal women have been gaining visibility. This study investigated the skin response to a phytoestrogen-enriched cosmetic formulation created by incorporating a biotransformed soybean extract (BE) into a cream-like matrix. Collagen-I expression was analyzed both in vitro (fibroblast cells) and ex vivo (skin explants). The results revealed an increased amount of collagen-I both in fibroblasts and human skin when treated with BE and BE-incorporated cream. Also, this collagen-I overexpression was inhibited by PHTPP, indicating a dependence on estrogen hormone receptor beta (ERβ) signaling. Moreover, BE was not harmful to skin microbiota, showing a promising nutricosmetic potential. Thus, this work presented a fully functional cream-like formulation that was shown to be safe and effectively increase collagen-I levels both in vitro and ex vivo.

Association of sleep disturbances with sarcopenia and its defining components: the ELSA-Brasil study

Sarcopenia and sleep problems share common physiopathology. We aimed to investigate the association of sleep disturbances with sarcopenia and its defining components in Brazilian middle-aged and older adults. In this cross-sectional analysis of the second wave of the ELSA-Brasil study, we included data from 7948 participants aged 50 years and older. Muscle mass was evaluated by bioelectrical impedance analysis and muscle strength by hand-grip strength. Sarcopenia was defined according to the Foundation for the National Institutes of Health criteria. Sleep duration and insomnia complaint were self-reported. Short sleep duration was considered as ≤6 h/night and long sleep duration as >8 h/night. High risk of obstructive sleep apnea (OSA) was assessed using the STOP-Bang questionnaire. Possible confounders included socio-demographic characteristics, lifestyle, clinical comorbidities, and use of sedatives and hypnotics. The frequencies of sarcopenia, low muscle mass, and low muscle strength were 1.6, 21.1, and 4.1%, respectively. After adjustment for possible confounders, high risk of OSA was associated with low muscle mass (OR=2.17, 95%CI: 1.92-2.45). Among obese participants, high risk of OSA was associated with low muscle strength (OR=1.68, 95%CI: 1.07-2.64). However, neither short nor long sleep duration or frequent insomnia complaint were associated with sarcopenia or its defining components. In conclusion, high risk of OSA was associated with low muscle mass in the whole sample and with low muscle strength among obese participants. Future studies are needed to clarify the temporal relationship between both conditions.

Binge drinking and insomnia in students from health sciences at one university in Rio de Janeiro, Brazil

In spite of the many studies examining alcohol consumption, recent reviews have indicated that binge drinking has not been extensively studied. Furthermore, it is becoming increasingly clear that sleep is associated with many physiological functions and to drug addictions. The present study aimed to evaluate the relationship between alcohol binge drinking and insomnia in college students of health sciences. All first-year health sciences students (n=286) were evaluated in a cross-sectional study. Envelopes containing the Insomnia Severity Index (ISI), the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST), and questions capturing sociodemographic data were distributed and collected in classes. It was found that most non-drinkers were female (70.6%), although there were no sex-related differences in the number of binge drinkers (more than 5 drinks on each occasion at least once a week), allowing statistical comparison. The Mann-Whitney U test indicated that the ISI scores were significantly greater in female than male binge drinkers (P=0.014). Moderate or severe insomnia was reported by 23% of the sample, with alcohol being the most frequently associated substance. A specialized intervention was suggested by ASSIST: brief for marijuana (19.2%) and tobacco (23.3%) use, and moderate (31.5%) or intensive (1.4%) for alcohol consumers. The data highlighted the need to pay attention to the habits of college students beyond obtaining scientific information. New data suggesting the influence of genetics on insomnia may be of importance when performing additional studies on the sex differences in alcohol binge drinking.

Tumor venéreo transmissível canino com resistência quimioterápica e metástase esplênica. Relato de caso / Canine transmissible venereal tumor with chemotherapy resistance and splenic metastasis. Case report

RESUMO O Tumor Venéreo Transmissível Canino (TVTC) é uma neoplasia de células redondas que tem a particularidade de se implantar em mucosas que tenham perdido a sua integridade. Nesse local o tumor prolifera e ocasionalmente origina metástase. Em geral, o tumor responde ao tratamento com sulfato de vincristina, porém a resistência quimioterápica associada ao fenótipo tumoral tem sido documentada. Objetivou-se relatar um caso de TVTC genital de fenótipo citológico misto com metástase esplênica e o insucesso da quimioterapia com sulfato de vincristina, em uma fêmea canina, da raça Australian Cattle Dog, de cinco anos de idade. Após diagnóstico citológico e histológico, o tumor primário foi ainda caracterizado em fase de progressão e mostrou baixa expressão de moléculas do complexo principal de histocompatibilidade (MHC) (4,4 ± 2% classe I e 11 ± 4,1% classe II). A cadela foi submetida à ovariohisterectomia e esplenectomia terapêutica e não apresentou recidiva do tumor após 12 meses de acompanhamento clínico.

ABSTRACT The canine transmissible venereal tumor is a type of round cell cancer that have the particularity of implanting in mucous tissue, when they lose their integrity, at which point the tumour proliferates and may even develop metastases. The tumor typically responds well to vincristine sulfate chemotherapy, although there are cases of resistance to the drug correlated with the tumoral phenotype. We describe herein a genital mixed TVTC case with metastases at spleen and failure at vincristine sulfate chemotherapeutic treatment in a five years old Australian Cattle Dog female. After the cytological, histological and cytogenetic diagnostic, the primary tumor was still characterized in progression phase and showed low major histocompatibility complex expression MHC (4,4 ± 2% class I e 11 ± 4,1% class II. The dog underwent therapeutic splenectomy and ovariohysterectomy and did not present tumor recurrence within 12 months of clinical follow-up.

Avaliação proteica do humor aquoso de equinos / Evaluation of equine aqueous humor protein

A avaliação proteica do humor aquoso (HA) pode ser utilizada como método diagnóstico nas uveítes. Entretanto, estudos sobre as proteínas nesse fluido, em equinos hígidos, são escassos e apresentam variações conforme a metodologia empregada. Dessa forma, objetivou-se realizar a análise proteica e citológica do HA nessa espécie, bem como verificar sua correlação com as proteínas plasmáticas. Foram avaliados 13 equinos adultos (26 olhos), sem raça definida, machos ou fêmeas. Mediante aqueocentese, foi coletado 0,5 mL de humor aquoso de cada olho. Cada amostra foi encaminhada para quantificação proteica pelo método de Bradford modificado e pela eletroforese em gel de poliacrilamida - dodecil sulfato de sódio (SDS-PAGE), bem como para avaliação citológica. Por meio de venopunção, coletou-se sangue para determinação da concentração de proteínas séricas. Treze olhos (50% das amostras) apresentaram valor proteico médio de 40,3 mg/dL±6,45 e a eletroforese demonstrou presença de proteínas de massas mais elevadas que 43 KDa. Houve ausência de células em 96,15% das amostras (25 olhos). Equinos hígidos apresentaram baixa concentração de proteínas no HA. Já a correlação entre proteína no humor aquoso/proteína plasmática total foi de 0,56%.(AU)

Evaluation of equine aqueous humor (AH) proteins can help the diagnosis of uveitis. However, studies on proteins in this fluid in healthy horses are scarce and present variations according to the methodology employed. This study aimed to perform protein analysis and cytology of equine aqueous humor of healthy horses and verify its correlation with plasmatic proteins. Thirteen adult horses (26 eyes), mixed breed, male or female were evaluated. A volume of 0.5 mL of aqueous humor was collected through aqueocentesis from both eyes. The samples were submitted to protein quantification by modified Bradford method and to sodium dodecyl sulphate - polyacrylamide gel electrophoresis (SDS-PAGE), and to cytological evaluation. Blood was collected for determination of plasmatic protein concentration. Thirteen eyes (50% of the samples) had values larger than zero by the Bradford method, with an average of 40.3 mg/dl±6.45. Electrophoresis showed presence of higher masses of proteins (43 KDa). There were no cells in 96.15% of the samples (25 eyes). Healthy equines presented low protein concentration in the HA. The ratio between protein concentration in the aqueous humor / total plasma protein of 0.56%.(AU)

Effect of hydrocooling, packaging, and cold storage on the post-harvest quality of peppermint (Mentha piperita L. ) / Efeito do hidroresfriamento e embalagem sobre hortelã-pimenta fresca armazenada em temperatura ambiente e ambiente refrigerado

ABSTRACT The purpose of this study was to assess the effects of hydrocooling and polyethylene terephthalate (PET) perforated and non-perforated packaging on post-harvest quality of peppermint (Mentha piperita L.) leaves stored at 5 and 25ºC. The experiments were conducted using a subdivided parcel layout in a completely randomized design with four replicates. Each parcel used a 2x3 layout (two hydrocooling treatments and three packaging treatments) with subparcels for storage time. The shelf life, chlorophyll content, mass loss (ML), relative water content (RWC), total soluble sugars (TSS), reducing sugars (Red), non-reducing sugars (NRed) and starch of the leaves were determined. Cold storage increased the shelf life of the peppermint by up to 64 times (>15 days). Hydrocooling increased the RWC of the leaves. Plastic packaging was effective in maintaining the RWC. Unperforated packages more effectively prevented ML in the peppermint leaves and prevented the leaves from wilting for a longer period of time. The chlorophyll content of the leaves varied according to the treatment. The soluble sugars and starch levels varied according to RWC. Hydrocooling with the use of non-perforated plastic packages was the most effective method for maintaining the postharvest quality of the peppermint.

RESUMO O trabalho objetivou avaliar os efeitos do hidroresfriamento e da embalagem de politereftalato de etileno (PET) perfurada e não perfurada na qualidade pós-colheita de folhas de hortelã pimenta (Mentha piperita L.) armazenadas em temperatura ambiente e sob refrigeração. Os experimentos foram instalados seguindo o esquema de parcela subdividida, tendo na parcela o esquema fatorial 2x2 (dois tratamentos envolvendo hidroresfriamento e dois tratamentos envolvendo embalagens) e nas subparcelas os tempos de armazenamento no delineamento inteiramente casualizado com quatro repetições. Foi determinada a vida de prateleira, os teores de clorofila, a perda de massa fresca (PM), o teor relativo de água (TRA), os teores de açúcares solúveis totais (AST), redutores (RED), não redutores (NRED) e amido das folhas. O armazenamento refrigerado aumentou em até 64 vezes (>15 dias) a vida de prateleira de hortelã-pimenta. O hidroresfriamento aumentou o TRA das folhas. A embalagem plástica foi efetiva no aumento da vida de prateleira de hortelã-pimenta sendo eficiente na manutenção dos TRA das folhas. A embalagem não perfurada foi mais eficiente na prevenção da PM. O teor de clorofila das folhas variou de acordo com o tratamento. AST, RED, NRED e amido variaram de acordo com TRA nas folhas. O hidroresfriamento juntamente com utilização de embalagem não perfurada foi o método mais eficiente na manutenção da qualidade pós-colheita de hortelã-pimenta.

Epidural levobupivacaine alone or combined with different morphine doses in bitches under continuous propofol infusion / Levobupivacaína isolada ou associada à morfina em diferentes doses pela via peridural em cadelas sob infusão contínua de propofol

The aim of this study was to assess the cardiopulmonary, analgesic, adverse effects, serum concentration of cortisol and plasma levels of levobupivacaine and morphine in bitches undergoing propofol anesthesia and epidural analgesia with levobupivacaine alone or combined with morphine. This was a randomized 'blinded' prospective clinical study using 32 adult bitches weighing 9.8±4.1kg that were admitted for elective ovariohysterectomy. Twenty minutes after administration of acepromazine and midazolam, anesthesia was induced with propofol (4mg kg-1) and maintained by a continuous rate infusion (CRI). Each animal was randomly assigned to one of four epidural groups: GL = levobupivacaine alone (0.33mg kg-1); GLM0.1 = levobupivacaine and morphine (0.1mg kg-1); GLM0.15 = levobupivacaine and morphine (0.15mg kg-1); and GLM0.2 = levobupivacaine and morphine (0.2mg kg-1)...

Objetivou-se avaliar os efeitos cardiovasculares, analgésico, adversos, a concentração sérica de cortisol e os níveis plasmáticos de levobupivacaína e morfina em cadelas submetidas à infusão contínua de propofol e analgesia peridural com levobupivacaína isolada ou associada à morfina. Para tanto, realizou-se um estudo clínico prospectivo randomizado com 32 cadelas adultas pesando 9,8 ± 4,1kg, que foram submetidas à ovário-histerectomia eletiva. Vinte minutos após a administração de acepromazina e midazolam, os animais foram induzidos com propofol (4mg/kg) e mantidos por uma infusão contínua (CRI) do mesmo fármaco. Cada animal foi alocado aleatoriamente em um dos quatro grupos: GL = levobupivacaína isolada (0,33mg/kg); GLM0,1 = levobupivacaína + morfina (0,1mg/kg); GLM0,15 = levobupivacaína + morfina (0,15mg/kg) e GLM0,2 = levobupivacaína + morfina (0,2mg/kg)...

Potencial de óleos essenciais de plantas medicinais no controle de fitopatógenos / Potential of essential oils from medicinal plants to control plant pathogens

Além do valor como recurso terapêutico, plantas medicinais também possuem potencial para serem utilizadas como fonte de princípios ativos contra fitopatógenos. O objetivo deste trabalho foi avaliar o efeito de óleos essenciais das espécies medicinais Baccharis dracunculifolia (alecrim-do-campo), Schinus terebinthifolius (aroeirinha) e Porophyllum ruderale (arnica-brasileira) sobre o crescimento dos fungos fitopatogênicos Fusarium oxysporum f. sp. phaseoli (Fop), F. solani f. sp. phaseoli (Fsp), Sclerotinia sclerotiorum (Ss), S. minor (Sm), Rhizoctonia solani (Rs), Sclerotium rolfsii (Sr) e Macrophomina phaseolina (Mp). Avaliou-se em placas de Petri o crescimento radial desses fungos em meio batata-dextrose-ágar (BDA) com cinco concentrações (0, 250, 500, 1000 e 3000 mg L-1) dos óleos essenciais. Discos de micélio (5 mm de diâmetro) de cada fungo em crescimento foram transferidos para placas de Petri que foram mantidas a 23°C no escuro por 48 horas. O óleo essencial de alecrim-do-campo foi o mais eficiente na redução do crescimento micelial de todos os fungos, com inibição completa quando se utilizou a concentração de 3000 mg L-1. A redução de crescimento variou de 29% (Fs) a 80% (Rs) a 250 mg L-1 do óleo essencial de alecrim-do-campo; a 500 mg L-1, variou de 29% (Fs) a 98% (Sr); e a 1000 mg L-1, de 41% (Fs) a 100% (Sr). A redução do crescimento dos fungos pelo óleo de aroeirinha na concentração de 3000 mg L-1 variou de 27% (Fsp) a 74% (Rs). Nessa concentração, o óleo de arnica-brasileira reduziu o crecimento micelial de Ss em 72%, o de Rs em 80% e o de Mp em 82%, sem efeitos significativos sobre o crescimento micelial de Fsp e Fop. Conclui-se que os óleos essenciais de alecrim-do-campo, aroeirinha e arnica-brasileira possuem potencial para o controle dos fungos fitopatogênicos estudados, com destaque para o óleo de alecrim-do-campo.

In addition to their value as therapeutic resources, medicinal plants also have the potential to be used as a source of alternative compounds against plant pathogens. The objective of this study was to evaluate the effect of essential oils extracted from the medicinal species Baccharis dracunculifolia, Schinus terebinthifolius and Porophyllum ruderale on the growth of the fungal plant pathogens Fusarium oxysporum f. sp. phaseoli (Fop), F. solani f. sp. phaseoli (Fsp), Sclerotinia sclerotiorum (Ss), S. minor (Sm), Rhizoctonia solani (Rs), Sclerotium rolfsii (Sr) and Macrophomina phaseolina (Mp). The radial mycelial growth of the fungi was evaluated on potato dextrose agar (PDA) in Petri dishes with five concentrations (0, 250, 500, 1000 and 3000 μL L-1) of the essential oils. Mycelial discs (5 mm diameter) of the growing colonies of each fungus were transferred to Petri dishes, which were maintained at 23 °C in the dark for 48 hours. The essential oil of B. dracunculifolia was the most effective oil in the reduction of the mycelial growth of all fungi. It completely inhibited their growth at 3000 mg L-1. At 250 mg L-1, the growth reduction caused by the oil of B. dracunculifolia varied from 29% (Fs) to 80% (Rs); at 500 mg L-1, it varied from 29% (Fs) to 98% (Sr); and at 1000 mg L-1, it varied from 41% (Fs) to 100% (Sr). The reduction of the mycelial growth caused by the oil of S. terebinthifolius at 3000 mg L-1 varied from 27% (Fsp) to 74% (Rs). At this concentration, the oil of P. ruderale reduced the mycelial growth of Ss by 72%, of Rs by 80% and of Mp by 82%, without significant effects on the mycelial growth of Fsp and Fop. We conclude that the essential oils of B. dracunculifolia, S. terebinthifolius and P. ruderale have the potential to be used to control the plant pathogens tested, especially the oil of B. dracunculifolia.

Classical and recent advances in the treatment of inflammatory bowel diseases

Crohn's disease (CD) and ulcerative colitis (UC) are intestinal disorders that comprise the inflammatory bowel diseases (IBD). These disorders have a significant effect on the quality of life of affected patients and the increasing number of IBD cases worldwide is a growing concern. Because of the overall burden of IBD and its multifactorial etiology, efforts have been made to improve the medical management of these inflammatory conditions. The classical therapeutic strategies aim to control the exacerbated host immune response with aminosalicylates, antibiotics, corticosteroids, thiopurines, methotrexate and anti-tumor necrosis factor (TNF) biological agents. Although successful in the treatment of several CD or UC conditions, these drugs have limited effectiveness, and variable responses may culminate in unpredictable outcomes. The ideal therapy should reduce inflammation without inducing immunosuppression, and remains a challenge to health care personnel. Recently, a number of additional approaches to IBD therapy, such as new target molecules for biological agents and cellular therapy, have shown promising results. A deeper understanding of IBD pathogenesis and the availability of novel therapies are needed to improve therapeutic success. This review describes the overall key features of therapies currently employed in clinical practice as well as novel and future alternative IBD treatment methods.

Performance of lactating crossbred cows on pasture supplemented with conventional urea or slow release urea / Desempenho de vacas mestiças lactantes em pasto suplementadas com ureia convencional ou ureia de liberação lenta

The effect of using conventional urea (CU) or slow release urea (SRU) was evaluated by replacing soybean meal (SBM) in concentrated supplements in levels of 2, 4 or 6% (dry matter basis) on productive performance of crossbred Holstein x Zebu lactating dairy cows (499±61kg body weight and 167 days of lactation) grazing on elephant grass (11.5% CP and 60% NDF) under rotational grazing during the rainy season. A supplement control (no urea) was used containing SBM as a protein source. A total of 21 cows were distributed an incomplete randomized block design with three periods of 21 days each (14 days of adaptation and seven days of collection). The animals entered the paddocks with a pasture height of 110-120cm and left when the grass reached the height of 40-50cm. The concentrated isonitrogenous supplements (24% crude protein, dry matter basis) were provided in the amount of 3.2kg/cow/day (fed basis). There was no effect (P>0.05) on source of crude protein (SBM vs source NPN), source NPN, level of NPN, interaction between source NPN and level of NPN on milk production (10.0kg/day), fat milk production corrected to 3.5% (10.7kg/day), levels of fat (4.01%), protein (3.66%), lactose (4.16%), total solids (12.86%) and non-fat solids (8.60%) in milk. The replacement of CU by SRU does not promote improvement in the productive performance of crossbred dairy cows grazing on elephant grass during the rainy season. Urea (CU or SRU) can be included in up to 6% of the DM concentrated supplements, replacing SBM, without affecting the productive performance of crossbred cows (Holstein x Zebu) in pasture during the rainy season...

Avaliou-se o efeito da utilização de ureia convencional (UC) ou de ureia de liberação lenta (ULL) em suplementos concentrados, nos níveis de 2, 4 ou 6% (base da matéria seca), em substituição ao farelo de soja, sobre o desempenho produtivo de vacas mestiças Holandês x Zebu (499±61kg de peso corporal e 167 dias de lactação) mantidas em pastos de capim-elefante (11,5% de proteína bruta e 60% de FDNcp), sob lotação intermitente, no período das chuvas. Um suplemento controle (sem ureia) foi utilizado contendo farelo de soja como fonte proteica. Foram utilizadas 21 vacas, distribuídas em delineamento em blocos incompletos balanceados, com três períodos de 21 dias cada (14 dias de adaptação e sete dias de coleta). Os animais entraram nos piquetes com altura do pasto de 110-120cm e saíram quando atingiram altura de 40-50cm. Os suplementos concentrados isonitrogenados (24% de proteína bruta, base da matéria seca) foram fornecidos na quantidade de 3,2kg/vaca/dia (base da matéria natural). Não houve efeito (P>0,05) de fonte de proteína bruta (farelo de soja vs. fonte de NNP), de interação entre fonte de NNP (UC vs. ULL) e nível de NNP (2, 4 e 6% na MS do suplemento), de fonte de NNP e de nível de NNP e sobre a produção de leite (10,0kg/dia), produção de leite corrigida para 3,5% de gordura (10,7kg/dia), teores de gordura (4,01%), proteína (3,66%), lactose (4,16%), extrato seco total (12,86%) e extrato seco desengordurado (8,60%) no leite. A substituição da ureia convencional pela ULL não promove melhoria no desempenho produtivo de vacas leiteiras mestiças em pastagem de capim-elefante, no período das chuvas. A ureia (convencional ou de liberação lenta) pode ser incluída em até 6% na MS de suplementos concentrados, em substituição ao farelo de soja, sem afetar o desempenho produtivo de vacas mestiças (Holandês x Zebu) em pastagem, no período das chuvas...

Evaluación de un programa de entrega de frutas con educación nutricional en escuelas públicas rurales de la Región Metropolitana, Chile / Evaluation of a fruits delivery program with nutrition education in rural public schools from the Metropolitan Region, Chile

The objective of this study was to assess the delivery of fruits with nutrition education in rural schools measuring its impact on food knowledge, food consumption and children nutritional status. A longitudinal quasi-experimental study of one year was carried out in an experimental group with delivery of fruits plus nutrition education, compared with a control group. Subjects were 784 school children (preschool to 8th grade) in 5 basic schools in María Pinto and 192 in the control group in Curacaví. Nutritional status, food knowledge, food consumption, the amount of fruit distributed and customer satisfaction were evaluated. Results showed that 85% of preschool to 2nd grade and 68.2% 3th to 8th grade children reported to consume fruit as a snack at least 3 times perweek. In children from 3th to 8th grade dairy consumption (more than 2 times per day) increased from 62% to 74%, respectively (p<0.01). Consumption of fruit more than 2 times per day increased to 34.9%, and legumes intake more than twice per week increased 37.7% to 51.7% (p<0.0001). In preschool from 57.6% to 76.2% and vegetables consumption more than 2 times per day increased from 26.8% to 2nd grade children there was a significant increase in healthy food knowledge in the period of the intervention (p<0.0001), while in children from 3th to 8th grade there was a significant improvement in consumption of fish and dairy food (p<0.0001). In the control group there were no changes either in food knowledge or in fruit consumption, and no changes in nutritional status were observed in both groups. In conclusion, the success of the program resides in the improvement of food knowledge and fruit consumption as a protective factor. To achieve an impact in nutritional status is necessary the long-term continuity of the program.

El objetivo de la presente investigación fue evaluar la entrega de fruta, con educación nutricional en escuelas básicas rurales midiendo su impacto en conocimiento, consumo y estado nutricional de los niños. Para ello se realizó un estudio cuasi-experimental, de seguimiento longitudinal de un año de duración en niños intervenidos con educación nutricional y entrega de frutas, comparados con un grupo control. La muestra fue de 784 niños de prekinder a 8° básico de 5 escuelas de María Pinto y 192 de una escuela control en Curacaví. Se evaluó el estado nutricional, consumo de alimentos seleccionados, conocimientos sobre alimentación saludable y consumo de la fruta entregada y satisfacción de usuarios. Resultados: el 85% de los niños de prekinder a 2° básico y el 68,2% de 3° a 8° básico reportaron consumir fruta de colación 3 días a la semana. En niños de 3° a 8° básico aumentó el consumo en 2 o más porciones al día de lácteos, de 62% a 74% (p<0,01). El consumo diario de 2 o más frutas aumentó de 57,6% a 76,2% y de 2 o más porciones de verduras de 26,8% a 34,9% y las legumbres 2 o más veces por semana aumentaron de 37,7% a 51,7% (p<0,0001). Hubo un aumento significativo en el conocimiento de una alimentación saludable entre el inicio y final (p<0,0001) en niños de prekinder a 2° básico; en los de 3° a 8° básico el cambio fue significativo en pescados y lácteos (p<0,0001). El grupo control no presentó cambios en el conocimiento ni consumo (p>0,1). No hubo cambios significativos en el estado nutricional del grupo intervenido ni del control. Se concluye que el programa fue exitoso ya que se cumplió el propósito de aumentar el conocimiento y consumo de fruta como un factor protector de la salud y que para lograr impacto en el estado nutricional se requiere darle continuidad en el tiempo.

Association among genetic predisposition, gut microbiota, and host immune response in the etiopathogenesis of inflammatory bowel disease

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is a chronic disorder that affects thousands of people around the world. These diseases are characterized by exacerbated uncontrolled intestinal inflammation that leads to poor quality of life in affected patients. Although the exact cause of IBD still remains unknown, compelling evidence suggests that the interplay among immune deregulation, environmental factors, and genetic polymorphisms contributes to the multifactorial nature of the disease. Therefore, in this review we present classical and novel findings regarding IBD etiopathogenesis. Considering the genetic causes of the diseases, alterations in about 100 genes or allelic variants, most of them in components of the immune system, have been related to IBD susceptibility. Dysbiosis of the intestinal microbiota also plays a role in the initiation or perpetuation of gut inflammation, which develops under altered or impaired immune responses. In this context, unbalanced innate and especially adaptive immunity has been considered one of the major contributing factors to IBD development, with the involvement of the Th1, Th2, and Th17 effector population in addition to impaired regulatory responses in CD or UC. Finally, an understanding of the interplay among pathogenic triggers of IBD will improve knowledge about the immunological mechanisms of gut inflammation, thus providing novel tools for IBD control.

Comparação entre as medidas morfométricas de equinos Mangalarga Marchador de marcha batida e marcha picada / Comparison between the morphometric measures of Mangalarga Marchador horses of batida marcha and picada marcha

The present study aimed to compare the morphometric measurements of Mangalarga Marchador horses of batida and picada marcha. Twenty-two linear and eight angular measurements of 222 males (130 of batida marcha and 92 of picada marcha) and 266 females (168 of batida marcha and 98 picada marcha) were compared in a completely randomized design, consisting of two treatments: horses of batida and picada marcha. The results were submitted to analysis of variance and means were compared by Fisher test (P<0.05). It was concluded that most of the measures of Mangalarga Marchador horses of batida and picada marcha have similar values, however, there are differences between some angles of members...

Estudo Etnobotânico de plantas medicinais utilizadas pela Comunidade do Sisal no município de Catu, Bahia, Brasil / Ethnobotanical study of medicinal plants used by the Sisal Community in the city of Catu, Bahia, Brazil

A utilização de plantas medicinais é instintiva nos animais, visto que alguns destes buscam raízes, cascas, folhas ou frutos na tentativa de resolver seus males. O homem, por sua vez, aprendeu a utilizar estas informações empiricamente para fazer uso destes vegetais. A medicina popular é uma importante alternativa, provavelmente, a mais usada para a cura de doenças por parte de populações indígenas, quilombolas ou rurais. A Etnobotânica, por sua vez, encarrega-se de estudar e interpretar essa relação dos homens com o mundo vegetal. Devido ao seu grande potencial biológico e cultural, o Brasil apresenta uma infinidade de conhecimentos tradicionais e espécies vegetais importantes, o que torna esse país uma grande fonte de pesquisa na área. Visando avaliar o conhecimento tradicional da população rural do Sisal, Catu/Bahia, relacionado ao uso de plantas medicinais, este trabalho iniciou-se em julho de 2009, constando de entrevistas semi-estruturadas e estruturadas, gravações, registros fotográficos, coleta do material botânico indicado nas entrevistas com os informantes, tratamento do material coletado e incorporação ao Herbário da Universidade do Estado da Bahia (HUNEB). Foram identificadas e coletadas 54 espécies distribuídas em 46 gêneros e 28 famílias, sendo Lamiacaeae e Asteraceae as mais representativas. A maioria das plantas é constituída de ervas e cultivada nos quintais dos moradores. O estudo revelou que a comunidade apresenta uma medicina popular bastante rica, com grande diversidade de espécies vegetais e usos por parte da população.

The use of medicinal plants is instinctive in animals, since some of these seek roots, bark, leaves or fruits in an attempt to cure their diseases. Man, in turn, learned to use this information on the use of these plants empirically. Folk medicine is an important alternative, probably the most used to cure diseases by indigenous peoples, Afro-descendants and rural populations. Ethnobotany, in turn, undertakes to study and interpret the relationship of men with the plant world. Because of its great biological and cultural potential, Brazil has a wealth of traditional knowledge and important plant species, what makes this country a great source of research in the area. To evaluate the traditional knowledge of the rural population of Sisal, city of Catu, state of Bahia, Brazil, related to use of medicinal plants, this work began in July 2009, consisting of semi-structured and structured interviews, recordings, photographs, collection of botanical material indicated in the interviews with informants, treatment of the collected material and incorporation into the Herbarium of the University of Bahia (HUNEB). We identified and collected 54 species in 46 genera and 28 families, being Asteraceae and Lamiacaeae the most representative. Most plants are herbs grown in the backyards of the residents. The study revealed that the community has a very rich folk medicine, with a great diversity of plant species and uses by the population.

Aproveitamento de soro lácteo na formulação de bebidas com frutas e hortaliças / The use of whey in the formulation of beverages with fruits and vegetables

O uso do soro lácteo como complemento na formulação de alimentos visando ao seu aproveitamento é uma alternativa para a obtenção de novos produtos. Neste trabalho, desenvolveram-se bebidas à base de soro oriundo de queijo coalho tipo A com frutas e hortaliças. Na formulação das bebidas, utilizaram-se diferentes proporções entre soro lácteo, frutas e hortaliças, com adição de 10% de açúcar. Seis bebidas foram formuladas e submetidas a um teste de preferência, e as três primeiras colocadas foram submetidas a um teste de aceitação sensorial. As três preferidas foram as bebidas sabor graviola, morango e goiaba. A bebida sabor graviola obteve aceitação com as melhores notas nos atributos sensoriais cor, sabor, aparência e qualidade global, seguida pela formulação de sabor morango, mas sem diferença significativa (P>0,05). A bebida sabor goiaba teve o diferencial no atributo odor e superou as bebidas sabor graviola e morango (P<0,05). Conclui-se que é viável a elaboração de bebidas à base de soro de queijo coalho com frutas.

Comercialização de plantas medicinais no contexto da cadeia produtiva em Minas Gerais / Commercialization of medicinal plants in the context of the productive chain in Minas Gerais

A Política Nacional de Práticas Integrativas e Complementares no Sistema Único de Saúde (SUS) contribuiu para o incremento do uso e conhecimento das plantas medicinais brasileiras, incentivando e respaldando o cultivo por agricultores familiares e a inserção no mercado. O Programa de Desenvolvimento de Plantas Medicinais prioriza ações em toda a cadeia produtiva do cultivo à distribuição. O conhecimento da demanda e dos padrões de qualidade adequados permite que distribuidores e consumidores possam tomar decisões sobre a aquisição e oferta dos produtos medicinais. Entretanto, há carência de informações e tecnologias na cadeia produtiva, o que desfavorece o seu pleno desenvolvimento, condizente com o potencial de geração de renda e promoção da saúde. O objetivo deste trabalho foi identificar e analisar o padrão atual de obtenção e comercialização de plantas medicinais no Mercado Central de Belo Horizonte. Foram realizadas entrevistas semi-estruturadas com amostra representativa de 9 comerciantes das 23 lojas de plantas medicinais do Mercado Central, de acordo com o critério de acessibilidade descrito por Berquó. Os resultados demonstraram a precariedade desse setor quanto à obtenção das plantas medicinais, principalmente pela falta de conhecimento e informações na aquisição e venda dos produtos pelos consumidores e vendedores, respectivamente.

The National Politic Integrative and complementary Practices in Health System (SUS) contributed to the increased use and knowledge of Brazilian medicinal plants, which encourages and supports the growing of family farmers and their integration in efficient markets. The Program for the Development of Medicinal Plants prioritizes actions in the entire production chain from cultivation to distribution. Knowledge of demand and adequate quality standards allows distributors and consumers to make decisions on the acquisition and supply of medicinal products. However, there is a lack of information and technologies in this supply chain, which discourages its full development, consistent with the potential for income generation and health promotion presents. The objective of this study was to identify and analyze current patterns of production and marketing of medicinal plants in the Central Market of Belo Horizonte. We conducted semi-structured interviews with nine of the 23 stores trades of medicinal plants from the Central Market. Results showed the precarious nature of this sector in obtaining medicinal plants, mainly by lack of knowledge and information in the purchase and sale of products by consumers and sellers, respectively.

Cestodes Diphyllobothriidea parasitizing blackfin goosefish, Lophius gastrophysus Miranda-Ribeiro, 1915 / Cestoides Diphyllobothriidea parasitos de peixe sapo-pescador, Lophius gastrophysus Miranda-Ribeiro, 1915

Entre os meses de março de 2000 e dezembro de 2005, 87 espécimes de L. gastrophysus foram obtidos de supermercados e empresas de exportação localizadas nos municipios de Cabo Frio, Niteroi, Duque de Caxias e Rio de Janeiro. Os peixes foram necropsiados, filetados e seus órgãos investigados para presença de helmintos. Dois espécimes (2,3 por cento) estavam parasitados por plerocecoides de Diphyllobothrium Cobbold, 1858 na cavidade abdominal e serosa do intestino, com intensidade média de um parasito por peixe e abundância média de 0,02, mostrando baixo potencial infectivo. Este é o primeiro registro de plerocercoides de Diphyllobothrium sp. no peixe sapo-pescador.

Potencial alelopático de extratos aquosos de Melissa officinalis L. e Mentha x villosa L. na germinação e vigor de sementes de Plantago major L. / Allelopathic effect of extracts of Melissa officinallis L. and Mentha x villosa L. on seed germination and vigor of Plantago major L.

O objetivo do trabalho foi avaliar o efeito dos extratos aquosos de hortelã e melissa na germinação e vigor de sementes de tanchagem. O experimento foi conduzido no Departamento de Fitotecnia da Universidade Federal de Viçosa, no mês de abril de 2011. O delineamento utilizado foi o inteiramente casualizado com cinco tratamentos (testemunha, 25 por cento, 50 por cento, 75 por cento e 100 por cento do extrato aquoso de hortelã e melissa) e quatro repetições. Os extratos foram preparados utilizando a parte aérea das plantas, na proporção de 100g de planta para 1 L de água destilada. Foram utilizadas 50 sementes de tanchagem em cada caixa gerbox, previamente umedecido com os extratos aquosos (correspondentes aos tratamentos), estas foram levadas para germinar em câmara de germinação, em temperatura de 20°C, fotoperíodo de 16 horas luz e 8 horas escuro, por 14 dias. Durante esse tempo foram feitas às contagens diárias das sementes germinadas para calcular o índice de velocidade de germinação e ao final dos 14 dias foi calculada a porcentagem de germinação. Sementes de tanchagem não submetidas aos extratos aquosos de melissa e hortelã apresentaram-se mais vigorosas quando comparado com as concentrações, evidenciando o potencial alelopático de melissa e hortelã sobre a sua qualidade fisiológica.

The aim of this work was to evaluate the effect of aqueous extracts of Melissa officinallis and Mentha x villosa for the germination and vigor of Plantago major seeds. The experiment was conducted at the Plant Science Department, Federal University of Viçosa, in April 2011. The design was a completely randomized design with five treatments (control, 25 percent, 50 percent, 75 percent and 100 percent of the aqueous extract of Mentha x villosa and Melissa Officinallis) and four replications. The extracts were prepared utulizando the shoots of plants at the rate of 100g of plant to 1 L of distilled water. We used 50 Plantago major seeds in each box incubator and these were subsequently placed in a germination chamber. 14 days during the counting of germinated seeds per day to calculate the index of germination speed and the end of 14 days was the germination percentage. Plantago major seeds not subjected to aqueous extracts of lemon balm and mint showed higher values in the variables studied when compared to other concentrations, showing the allelopathic potencial of Melissa officinallis and Mentha x villosa on the development of plantain, determined by germinating.

Efeito das tinturas de café torrado e moído nos níveis séricos de colesterol, triglicerídeos e glicose em ratos diabéticos / Effect of tincture of ground roasted coffee on plasma levels of cholesterol, triglycerides and glucose in diabetic rats

O consumo de café tem sido associado ao menor risco de diabetes tipo 2 (DM2). Evidências epidemiológicas sugerem que o alto consumo de café pode reduzir o risco de diabetes mellitus. O presente trabalho teve como objetivo avaliar o efeito de tinturas de café torrado e moído nos níveis plasmáticos de colesterol, trigliceróis e glicose em ratos diabéticos. A indução do diabetes foi realizada através da administração intraperitoneal de aloxano e as tinturas foram elaboradas utilizando café torrado e moído. Após 30 dias de tratamento, foram realizadas determinações bioquímicas. As tinturas de café solúvel promoveram aumento nos níveis de colesterol e as percentagens de redução das concentrações de glicose e triacilglicerídeo variaram entre 20 e 24% e entre 51 a 57%, respectivamente. A partir dos resultados obtidos, concluiu-se que os tratamentos com o café solúvel sustentam a hipótese de que o café está associado ao menor risco de DM2.

The consumption of coffee has been associated with a lower risk of type 2 diabetes (DM). Epidemiological evidence suggests that high consumption of coffee may reduce the risk of diabetes. The aim of this study was to assess the effects of a tincture (hydroethanolic extract) of roasted and ground coffee on plasma levels of cholesterol, triglycerides and glucose in diabetic rats. The diabetes was induced by intraperitoneal administration of alloxan. The induced diabetic rats were then treated for 30 days by gavage with various doses of the coffee tincture. After the treatment, biochemical blood tests were carried out on the rats. The coffee tincture provoked moderately increased levels of cholesterol, but the concentrations of glucose and triglycerides were reduced by 20-24% and 51-57%, respectively. From these results, it was concluded that the treatment with coffee extract supports the hypothesis that coffee is associated with a lower risk of type 2 DM.
