Do Herbal Supplements and Probiotics Complement Antibiotics and Diet in the Management of SIBO? A Randomized Clinical Trial.

Small intestinal bacterial overgrowth (SIBO) arises from dysbiosis in the small intestine, manifesting with abdominal symptoms. This study aims to assess the efficacy of combined antibiotic therapy, herbal supplements, probiotics, and dietary modifications in SIBO management. A total of 179 SIBO-diagnosed patients underwent clinical evaluation and breath testing. Patients were categorized into hydrogen (H2-SIBO) and methane (CH4-SIBO) groups. The control group received standard antibiotic therapy and a low-FODMAP diet, while the intervention group received additional herbal antibiotics, probiotics, and prebiotics. After treatment, both groups exhibited reduced gas levels, particularly in CH4-SIBO. Clinical remission rates were higher in the intervention group, especially in CH4-SIBO cases. Logistic regression analysis showed gas concentrations at diagnosis as significant predictors of treatment success. In conclusion, adjunctive herbal supplements and probiotics did not significantly impact gas levels, but showed potential for clinical improvement, especially in CH4-SIBO.

Effect of an Immune-Boosting, Antioxidant and Anti-Inflammatory Food Supplement in Hospitalized COVID-19 Patients: A Prospective Randomized Pilot Study.

BACKGROUND: COVID-19 disease is a serious global health problem. Few treatments have been shown to reduce mortality and accelerate time to recovery. The aim of this study was to evaluate the potential effect of a food supplement (probiotics, prebiotics, vitamin D, zinc and selenium) in patients admitted with COVID-19. METHODS: A prospective randomized non-blinded clinical trial was conducted in a sample of 162 hospitalized patients diagnosed with COVID-19 recruited over eight months. All patients received standard treatment, but the intervention group (n = 67) was given one food supplement stick daily during their admission. After collecting the study variables, a statistical analysis was performed comparing the intervention and control groups and a multivariate analysis controlling for variables that could act as confounding factors. RESULTS: ROC curve analysis with an area under the curve (AUC) value of 0.840 (p < 0.001; 95%CI: 0.741-0.939) of the food supplement administration vs. recovery indicated good predictive ability. Moreover, the intervention group had a shorter duration of digestive symptoms compared with the control group: 2.6 ± 1.3 vs. 4.3 ± 2.2 days (p = 0.001); patients with non-severe disease on chest X-ray had shorter hospital stays: 8.1 ± 3.9 vs. 11.6 ± 7.4 days (p = 0.007). CONCLUSIONS: In this trial, the administration of a food supplement (Gasteel Plus®) was shown to be a protective factor in the group of patients with severe COVID-19 and allowed early recovery from digestive symptoms and a shorter hospital stay in patients with a normal-mild-moderate chest X-ray at admission (ClinicalTrials.gov number, NCT04666116).

Macronutrients and micronutrients in Spanish adult vegans (Mediterranean population).

INTRODUCTION: Objective: studies have been published in Europe comparing the mean macronutrient and micronutrient intake values of the general population with those of the vegan population, but none has been conducted in a country that mainly follows the Mediterranean diet. Therefore, the aim of this study was to carry out this comparison in Spain. Methods: a cross-sectional study of a sample of Spanish vegans was designed in 2015. To compare the distribution of nutrients with those of the general population, we used data from the Spanish Agency for Food Safety and Nutrition, which was considered to be normally distributed as it was a large population with biological parameters. All participants were asked about their dietary intake for the previous day (24 hour reminder) and the nutrients were calculated using specialized software. The distributions were compared using the Kolmogorov-Smirnov test. Results: The sample comprised 102 vegans, 67 of whom were women. The vegan population consumed more carbohydrates and fiber, less total fat (women only), fewer saturated fatty acids, and more polyunsaturated fatty acids. They had much lower cholesterol intake, lower calcium and iodine intake, higher iron and folic acid intake, and much lower intake of vitamins B12 and D. Conclusions: Spanish vegans had nutritional deficiencies compared to the general population and should therefore ensure their diet includes the necessary supplements.

INTRODUCCIÓN: Antecedentes: se han publicado en Europa estudios que comparan los valores medios de ingesta de macronutrientes y micronutrientes de la población general con los de la población vegana, pero ninguno se ha llevado a cabo en un país que sigue principalmente la dieta mediterránea. Por lo tanto, el objetivo de este estudio fue llevar a cabo esta comparación en España. Métodos: se diseñó un estudio transversal de una muestra de veganos españoles en 2015. Para comparar la distribución de nutrientes con los de la población general, utilizamos datos de la Agencia Española de Seguridad Alimentaria y Nutrición, considerando dichos datos como una distribución normal de parámetros biológicos al constituir una gran muestra. A todos los participantes se les preguntó sobre su ingesta dietética en el día anterior y los nutrientes se calcularon utilizando un software especializado. Las distribuciones se compararon mediante la prueba de Kolmogorov-Smirnov. RESULTADOS: La muestra comprendió 102 veganos, 67 de los cuales eran mujeres. La población vegana consumió más carbohidratos y fibra, menos grasa total (solo mujeres), menos ácidos grasos saturados y más ácidos grasos poliinsaturados. Tenían una ingesta mucho más baja de colesterol, una ingesta más baja de calcio y yodo, una mayor ingesta de hierro y ácido fólico, y una ingesta mucho más baja de vitaminas B12 y D. Conclusión: los veganos españoles tenían deficiencias nutricionales en comparación con la población general y, por lo tanto, deben asegurarse de que su dieta incluya los suplementos necesarios.

Influence of Olive Extracts on the Expression of Genes Involved in Lipid Metabolism in Medaka Fish.

Aims. To assess the possible effect of polyphenol-rich olive extracts on lipid metabolism in medaka fish by quantifying the expression of lipogenic and lipolytic genes. Materials and methods. Adult medaka fish were maintained in tanks for five days with five extracts at 0.01% in water, causing obesity through a diet rich in carbohydrates, with a control group maintained in water with a normal diet. The extracts contained polyphenols ranging between 7 and 116 mg/g (oleuropein, hydroxytyrosol) with an antioxidant power of 2-13 mmol of 2,4,6-tri(2-pyridyl)-1,3,5-triazine/100 g. After five days, the fish were sacrificed and the hepatic mRNA and its complementary DNA were extracted by reverse transcription. Complementary DNAs were quantified for three lipolytic and three lipogenic genes by real-time PCR. The relative gene expression was calculated from the amplification curves in reference to the control group. Results. The expression of genes involved in lipolysis, including peroxisome proliferator-activated receptor-±, acyl-CoA oxidase 1, and carnitine palmitoyltransferase 1, were clearly decreased in fish subjected to an obesogenic diet, and this situation could not be reversed in fish maintained with polyphenol-rich extracts. In contrast, lipogenic fatty acid synthase, acetyl-CoA carboxylase 1, and sterol regulatory element-binding protein 1 genes increased considerably with the obesogenic diet and reverted to the normal state with the olive extracts. The effect was not dependent on the total polyphenol content, the specific oleuropein or hydroxytyrosol concentration, or the antioxidant power, suggesting a synergistic effect. Conclusion. Olive polyphenols, acting as anti-lipogenic agents, have a positive effect on lipid metabolism, but their mechanism in each gene is different according to the extract, which supports synergistic mechanisms with the different proportions of polyphenols and accompanying phytochemicals in each extract.

Factors associated with moderate neonatal hyperthyrotropinemia.

BACKGROUND: Maternal iodine deficiency is related to high neonatal thyroid-stimulating hormone (TSH) values, with the threshold of 5 mIU/L recommended as an indicator of iodine nutrition status. The objective of this study was to analyse possible risk factors for increased TSH that could distort its validity as a marker of iodine status. The clinical relevance of this research question is that if the factors associated with iodine deficiency are known, iodine supplementation can be introduced in risk groups, both during pregnancy and in newborns. METHODS: A case-control study was carried out in a sample of 46,622 newborns in 2002-2015 in Spain. Of these, 45,326 had a neonatal TSH value ≥5 mIU/L. The main variable was having TSH ≥5 mIU/L and the secondary variables were: sex, gestational age, day of sample extraction and maternal origin. Associated factors were analysed through a logistic regression model, calculating the odds ratio (OR). RESULTS: The factors associated with this outcome were: male sex (OR = 1.34, 95% CI: 1.20-1.50, p<0.001), originating from an Asian/Oceanic country (OR = 0.80, 95% CI: 0.54-1.20, p = 0.536) or Europe (OR = 0.80, 95% CI: 0.66-0.96, p = 0.285) (including Spain, OR = 1) [p<0.001 for America (OR = 0.54, 95% CI: 0.44-0.68) and p = 0.025 for Africa (OR = 0.78, 95% CI: 0.62-0.97)] and fewer days from birth to sampling (OR = 0.80, 95% CI: 0.77-0.82, p<0.001). CONCLUSIONS: The risk of high neonatal TSH without congenital hypothyroidism is higher in males, decreases with a greater number of days from birth to extraction, and is dependent on maternal ethnicity but not on gestational age.

Screening Tool to Determine Risk of Having Muscle Dysmorphia Symptoms in Men Who Engage in Weight Training at a Gym.

OBJECTIVE: Although 2 screening tests exist for having a high risk of muscle dysmorphia (MD) symptoms, they both require a long time to apply. Accordingly, we proposed the construction, validation, and implementation of such a test in a mobile application using easy-to-measure factors associated with MD. DESIGN: Cross-sectional observational study. SETTING: Gyms in Alicante (Spain) during 2013 to 2014. PARTICIPANTS: One hundred forty-one men who engaged in weight training. ASSESSMENT OF RISK FACTORS: The variables are as follows: age, educational level, income, buys own food, physical activity per week, daily meals, importance of nutrition, special nutrition, guilt about dietary nonadherence, supplements, and body mass index (BMI). A points system was constructed through a binary logistic regression model to predict a high risk of MD symptoms by testing all possible combinations of secondary variables (5035). The system was validated using bootstrapping and implemented in a mobile application. MAIN OUTCOME MEASURES: High risk of having MD symptoms (Muscle Appearance Satisfaction Scale). RESULTS: Of the 141 participants, 45 had a high risk of MD symptoms [31.9%, 95% confidence interval (CI), 24.2%-39.6%]. The logistic regression model combination providing the largest area under the receiver operating characteristic curve (0.76) included the following: age [odds ratio (OR) = 0.90; 95% CI, 0.84-0.97, P = 0.007], guilt about dietary nonadherence (OR = 2.46; 95% CI, 1.06-5.73, P = 0.037), energy supplements (OR = 3.60; 95% CI, 1.54-8.44, P = 0.003), and BMI (OR = 1.33, 95% CI, 1.12-1.57, P < 0.001). The points system was validated through 1000 bootstrap samples. CONCLUSIONS: A quick, easy-to-use, 4-factor test that could serve as a screening tool for a high risk of MD symptoms has been constructed, validated, and implemented in a mobile application.

Percepción de embarazadas y matronas acerca de los consejos nutricionales durante la gestación / Pregnant’s and midwives perception about nutrional councils during pregnancy

Introducción: el estado nutricional previo de la embarazada, la adecuada ganancia de peso y la ingesta de ciertos nutrientes pueden tener una influencia importante tanto para la madre como para el recién nacido, a corto y largo plazo. Las recomendaciones de la Organización Mundial de la Salud son transmitidas durante el control del embarazo por la matrona. Objetivos: analizar los principales estudios sobre la percepción de las embarazadas acerca de los consejos nutricionales recibidos e identificar las estrategias utilizadas por las matronas para su implementación. Metodología: búsqueda bibliográfica sobre embarazadas de bajo riesgo controladas por matronas y que reciben consejos nutricionales realizada en WOS, CINHAL y PubMed. Se utilizaron los descriptores: pregnancy, pregnant, midwife, counselling, nutrition y sus diferentes combinaciones. Los criterios de inclusión fueron artículos originales y revisiones en inglés, español o portugués de los últimos diez años y disponibles en texto completo. Resultados: se encontraron 184 referencias. Solo 11 tratan el tema abordado. Existen múltiples artículos con consejos nutricionales en el embarazo, pero muy pocos que incluyan estrategias educativas implementadas por las matronas que aborden recomendaciones dietéticonutricionales y su utilidad. Conclusión: existen escasos estudios que investiguen los conocimientos que las matronas tienen sobre nutrición en el embarazo y los consejos que aportan sobre el tema. Igualmente sucede con los trabajos que estudian la percepción que tienen las gestantes sobre los consejos nutricionales recibidos (AU)

Background: Women’s nutritional status, the suitable profit of weight and the ingestion of certain nutrients may have an important influence in health both for the mother and newborn in a short and long term. World Health Organization gives a number of nutritional recommendations which are transmitted during the pregnant women antenatal care by their midwives. Objectives: To analyze the main studies on the understanding of the pregnant women about the nutritional received councils and to identify the strategies used by the midwives for theirs implementation. Methodology: Literature review for low risk pregnant’s conducted by midwives and receiving nutritional councils in Web of Science (WOS), CINAHL and PubMed. Using descriptors such as: pregnancy, pregnant, midwife, counselling, nutrition and their different combinations. The criteria incorporation was original article and review written in English, Spanish or Portuguese of last ten years and available in complete. Results: 184 references were found. Finally, only 11 focused on the issue addressed. There are multiple items with nutritional advice in pregnancy but a few that include educational strategies implemented by midwives to address dietary and nutritional recommendations and usefulness. Conclusion: Only a few studies researchs the midwives’ knowledge about nutrition in pregnancy and the councils that they transmit to pregnants. In the same way, not many papers treats the pregnant perception about nutritional councils (AU)

Protection by polyphenol extract from olive stones against apoptosis produced by oxidative stress in human neuroblastoma cells

OBJECTIVE: We evaluated the protective activity of an extract from a by-product such as olive stones, through its ability to inhibit H202 induced apoptosis in the SH-SY5Y human neuroblastoma cell line. MATERIAL AND METHODS: To such end, 20,000 cells/well were cultivated and differentiation with retinoic acid was initiated. Once the cells were differentiated, apoptosis was induced with and without H2O2 extract. Finally, cDNA extraction was performed, and pro-apoptotic genes Bax and anti-apoptotic genes Bcl-2 were analyzed. Quantification of the gene expression was performed using the GAPDH gene marker. RESULTS: Cell viability with the extract is 97.6% (SD 5.7) with 10 mg/l and 62.8% (SD 1.2) to 50 mg/l, using 10 mg/l for the biomarker assay. The retinoic acid differentiated SH-S cell line (10 µM) shows a clear apoptosis when treated with H2O2 150 µM, with a Bax/Bcl-2 ratio of 3.75 (SD 0.80) in contrast to the differentiated control cells subjected to H2O2 and with extract, which have the same ratio of 1.02 (SD 0.01-0.03). CONCLUSION: The olive stone extract shows anti-apoptotic activity in the provoked cell death of SH-SY5Y human neuroblastoma cells in their normal state, defending them from oxidative stress which produces a significant increase in the apoptotic gene ratio in contrast to anti-apoptotic genes (Bax/Bcl-2).

Indicators of success in the dietary management of overweight and obesity: weight, body fat loss and quality / Indicadores de éxito en el tratamiento dietético del sobrepeso y la obesidad: pérdida de peso, grasa corporal y calidad de pérdida

Concepts: %WL: Percentage of weight loss; %FL: Percentage of fat loss. Objective: evaluate which unit of measurement for weight loss could determine the success or failure of dietary treatment for overweight and obesity. Method: 4,625 consultations carried out on 616 patients in the southeast of Spain from 2006 to 2012. All of the patients were over 25 years of age and suffered from overweight or obesity. The consultations were carried out every fortnight, using the Mediterranean or low-calorie diet. The patients were divided into four groups according to their %WL and %FL. Results: most of the sample consisted of: women; participants between 25-45 years of age; attended consultations for over a month and a half; obese. 80% of the patients obtained a %FL ≥ 5% (15.5 ± 12.8). The groups with a higher %FL obtained significant differences in weight loss (22.6 vs 11.2%, p = 0.000). The multinomial analysis shows significant differences between the groups with the highest %FL and the lowest %WL and %FL: sex (p = 0.006 vs p = 0.005), BMI (p = 0.010 vs p = 0.003) and attendance (p = 0.000 vs p = 0.000). Conclusion: the patients who lost < 5% of fat had higher initial parameters (percentage of weight and fat); most of the sample lost ≥ 5% of fat. This means that the method of personalised dietary treatment results in a high fat loss; fat is an indicator of the quality loss obtained. Recommendations: use the measurement of fat as a complementary unit of measurement to weight loss; establish a limit of 5% to evaluate such loss; and increase this type of research in any method of weight loss (AU)

Conceptos: %WL: Porcentaje de pérdida de peso; %FL: Percentage of fat loss. Objetivo: evaluar qué unidad de medida en la pérdida podría determinar el éxito o fracaso del tratamiento dietético en el sobrepeso y obesidad. Método: 4.625 consultas se llevaron a cabo con 616 pacientes mayores de 25 años con sobrepeso y obesidad, en el sur-este de España, durante los años 2006-12. Las consultas se realizaban quincenalmente, se utilizó la dieta mediterránea e hipo-calórica. Se formaron cuatro grupos en función del menor o mayor %WL y %FL. Resultados: la mayoría de la muestra está formada por: mujeres; participantes entre 25-45 años; asistentes a más de mes y medio; obesos. El 80% de los pacientes obtienen un %FL ≥ 5% (15,5±12,8). Los grupos con mayor %FL obtiene diferencias significativas en la pérdida (22,6 vs 11,2%, p=0,000). El análisis multinomial, destaca diferencias significativas cuando se compara los grupos de mayor %FL con el menor %WL y %FL: en el sexo (p=0.006 vs p=0.005), IMC (p=0.010 vs p=0.003) y asistencia (p=0.000 vs p=0.000). Conclusión: los pacientes que pierden < 5% de grasa, muestran parámetros iniciales mayores (Porcentaje de peso y grasa); la mayoría de la muestra pierde ≥ 5% de grasa, por lo que el tratamiento dietético individualizado es un método que obtiene una elevada pérdida de grasa; la grasa es un indicador de la calidad de la pérdida obtenida. Se recomienda: la medición de la grasa como unidad de medida complementaria al peso; establecer el límite del 5% para evaluar dicha pérdida; y aumentar la investigación en esta línea en cualquier método de pérdida (AU)

Anti-adipogenic activity of an olive seed extract in mouse fibroblasts.

UNLABELLED: The administration of different polyphenols protects against increased body weight and fat accumulation. The aim of the study was to determine the anti-adipogenic activity of an olive-seed polyphenolic extract, by means of mouse fibroblast cell line 3T3-L1 adipocyte differentiation. MATERIAL AND METHODS: Cells were incubated and differentiated (6000 cells/cup) in the presence of olive-seed extract at 10 and 50 mg/l biosecure concentrations of polyphenols, and with no extract in the control sample. After 5 to 7 days mature adipocytes are formed. The fat clusters are quantified by means of red-oil staining, 490 nm absorbance, and the expression of the leptin and PPARg genes, and then compared to the values obtained in the cultures before and after adipocyte differentiation. RESULTS: The control samples, with no extract, presented an accumulation of fat of 100%. By contrast, the addition of 50 mg/l of olive-seed extract polyphenols resulted in a 50% accumulation of fat, similar to that of the non-differentiated cells. A 10 mg/l extract concentration had no effect. Anti-adipogenic activity is thus confirmed, as the expression of the PPARg and leptin genes is reduced in adipocyte differentiation in the presence of extract at 50 mg/l. In conclusion, both the formation of fatty substances characteristic of adipogenesis, and the expression of the adipogenic PPARg and leptin genes are found to be inhibited by the prior addition of olive-seed extract polyphenols at a 50 mg/l concentration.

La administración de diferentes polifenoles protege contra el incremento de peso y la acumulación de grasa. Objetivo: comprobar la actividad anti-adipogénica de un extracto polifenólico de huesos de aceituna, utilizando la diferenciación a adipocitos de la línea celular 3T3-L1 de fibroblastos de ratón. Material y métodos: se cultivan y diferencian las células (6.000 células/pocillo) en presencia del extracto de huesos de aceitunas a 10 y 50 mg/l de polifenoles, concentraciones bioseguras, y sin extracto como control. A los 5-7 días se forman los adipocitos maduros. Se cuantifican los cúmulos de grasa formados mediante tinción con Oil- Red y medida de la absorbancia a 490 nm y la expresión de los genes de leptina y PPARg, relacionándolos con los valores en los cultivos antes y después de diferenciarse a adipocitos. Resultados: las muestras control, sin extracto, se consideran el 100% de acumulación de grasas. En contraste, la adición de 50 mg/l de extracto de polifenoles de huesos de aceituna muestra un cúmulo de grasa de alrededor del 50%, semejante a las células no diferenciadas. Con 10 mg/l de extracto no se muestra efecto. Se confirma la actividad antiadipogénica, observándose disminución en la expresión de los genes PPARg y de leptina en la diferenciación a adipocitos en presencia del extracto a 50 mg/l. En conclusión, la formación de los cuerpos grasos característicos de la adipogénesis queda inhibida previa adición de 50 mg/l de polifenoles de extracto de huesos de aceituna, así como la expresión de los genes adipogénicos PPARg y de leptina.

Factores de riesgo nutricionales para dismorfia muscular en usuarios de sala de musculación / Nutritional risk factors to users in dysmorphia muscular strength of room

Objetivo: Se muestra un estudio novedoso en el cual se han analizado la prevalencia y el tipo de suplementos consumidos entre usuarios de gimnasio de la provincia de Alicante que padecen dismorfia muscular (DM). Metodología: Se analizaron gimnastas de varias salas de musculación de Alicante (zona urbana del sureste español), donde se recogieron las medidas de 141 varones de edad comprendida entre 18-45 años, que persiguen el aumento de su masa muscular. Se tuvieron en cuenta el IMC (kg/m2 ), si consumían suplementos y que tipos. Y se ha determinado si padecían o no DM, a través de la Escala de satisfacción muscular. Resultados: La muestra está constituida por 141 varones, de los cuales 45 son DM y 96 no lo son. Un 89,9% y un 71,9% consumen o han consumido suplementos respectivamente. El consumo de los suplementos: proteínas, hidratos de carbono y creatina han resultado significativamente mayores entre los DM (p=0,007, p=0,016 y p=0,016 respectivamente). Los resultados del test Kidmed no han resultado significativos según el test Chi-cuadrado, pero con un porcentaje de dieta mediterránea superior en el grupo de los que padecen DM. Según el análisis multivariante son factores de riesgo el consumo de suplementos con una OR = 3.4 (IC95% = 1.1-10.9; p=0,041), el estar en sobrepeso con una OR = 20.9 (IC95% = 2.2-195.6; p=0,008) y ser obesos con OR = 15.5 (IC95% = 1.6-145.8; p=0,017). Conclusión: La prevalencia de consumo de suplementos tanto en DM como en no DM ha dado valores relativamente altos con respecto a la mayoría de estudios. Los suplementos mas consumidos fueron proteínas, creatina e hidratos de carbono. El riesgo de padecer DM aumenta con el grado de obesidad y el grado en que se consumen suplementos (AU)

Objective: To analyze the prevalence and diet supplements used among gym users with muscle dysmorphia (MD) in the province of Alicante. Methodology: Several gymnasts weights-lift rooms of the urban area of Alicante were analyzed, collecting measurements of 141 (18-45 years of age) males that pursue an increase in their muscle mass. BMI (kg/m2 ), type and consume of diet supplements have been checked; and has been determined whether or not the presence of DM through the muscle scale satisfaction. Results: The sample consisted of 141 men, of whom 45 are with MD and 96 not. 89.9% and 71.9% use or have used diet supplements respectively. The consumption of supplements: proteins, carbohydrates and creatine have been significantly higher in MD´s users (p=0.007, p=0.016 and p=0.016 respectively). The Kidmed´s test results have not been significant according to the Chi-square test, but with a higher percentage of the Mediterranean diet in the group of those with DM.

Según el análisis multivariante son factores de riesgo el consumo de suplementos con una OR = 3.4 (IC95% = 1.1-10.9; p=0,041), el estar en sobrepeso con una OR = 20.9 (IC95% = 2.2-195.6; p=0,008) y ser obesos con OR = 15.5 (IC95% = 1.6-145.8; p=0,017). Conclusión: La prevalencia de consumo de suplementos tanto en DM como en no DM ha dado valores relativamente altos con respecto a la mayoría de estudios. Los suplementos mas consumidos fueron proteínas, creatina e hidratos de carbono. El riesgo de padecer DM aumenta con el grado de obesidad y el grado en que se consumen suplementos.

[Effect on zebrafish neurodevelopment and neuroprotection of a polyphenolic extract olive seeds]. / Efecto sobre el neurodesarrollo y neuroprotección en pez cebra de un extracto polifenólico de huesos de aceituna.

OBJECTIVE: To determine the effect of a polyphenolic extract from olive pit on the development of the nervous system as well as its effect on pain induced by the neurotoxin kainic acid, taking the zebrafish as the animal model. MATERIAL AND METHODS: We analyse the effect of the extract at the maximum tolerated dose (100 mg/ml of polyphenols) on the cholinergic activity in zebrafish larvae (72 hours post-fertilization). Only fecundated eggs with no abnormalities are used. 6 eggs/bowl are incubated in a 24 bowls microplate in 2 ml of water with DMSO (0.1%) at 26 ± 1º C: a) neurodevelopment: water (control) and 100 mg/ml of extract, as an essay; b) neuroprotection: water and kainic acid (100 µM) (control) and 100 mg/ml of extract (essay). All incubations are in triplicate. After 72 h, incubations are examined and checked for any abnormalities. Larvae are homogenized and acetyl cholinesterase activity and protein concentration in supernatants is quantified. RESULTS: The quantity of protein and the morphologic appreciation is similar in all the essays, showing a standard development. Acetyl cholinesterase in fish larvae, with the polyphenolic extract is 162.2% (SD 44.2) compared to controls (100% of activity) (p < 0.01). Fish larvae treated with kainic acid and polyphenolic acid show 140.1% (SD 22.0) of activity, compared to those only incubated with the neurotoxin (100%) (p < 0.05). CONCLUSION: Polyphenols extracted from olive pit produce an increase in the cholinergic activity during the larvae neurodevelopment in the zebrafish as well as protection against the neurotoxin kainic acid.

Objetivo: Determinar el efecto de un extracto polifenólico de hueso de oliva en el desarrollo del sistema nervioso y frente al daño inducido mediante la neurotoxina ácido kaínico, utilizando como modelo animal el pez cebra. Material y métodos: Se analiza el efecto del extracto a la máxima dosis tolerada (100 mg/ml de polifenoles) sobre la actividad colinérgica en larvas de pez cebra (72 horas post-fertilización). Se utilizan únicamente huevos fecundados sin anomalías. Se incuban 6 huevos/pocillo en microplaca de 24 pocillos en 2 ml de agua con DMSO (0,1%) a 26 ± 1º C: a) neurodesarrollo: agua (control) y con 100 mg/ml de extracto, como ensayo; b) neuroprotección: agua y ácido kaínico (100 M) (control) y con 100 mg/ml de extracto (ensayo). Todas las incubaciones por triplicado. A las 72 h se examinan y verifica ausencia de anomalías. Las larvas se homogeneizan y en los sobrenadantes se cuantifica actividad acetilnolinesterasa y concentración proteínas. Resultados: La cantidad de proteína y apreciación morfológica es análoga en todos los ensayos, indicando mismo desarrollo. La acetilcolinesterasa en las larvas de pez, con el extracto polifenólico es del 162,2%(SD 44,2) respecto a controles (100% de actividad) (p < 0,01). Las larvas de pez tratadas con ácido kaínico y extracto polifenólico presentan el 140,1% (SD 22,0) de actividad, respecto a las incubadas únicamente con la neurotoxina (100%) (p < 0,05). Conclusión: Los polifenoles extraídos de los huesos de aceituna producen incremento de actividad colinérgica durante el neurodesarrollo larvario en el pez cebra y protección frente a la neurotoxina ácido kaínico.

[Anti-inflammatory activity of olive seed polyphenolic extract in the THP1-XBLUE-CD14 human monocytes cell line]. / Actividad antiinflamatoria de un extracto polifenólico de hueso de olivas en la línea celular de monocitos humanos THP1-XBLUE-CD14.

UNLABELLED: The aim of this study was to assess the anti-inflammatory activity of a polyphenolic extract from olive pits. MATERIAL AND METHODS: The THP1-XBlue-CD14 (invivogen) cellular line, 80,000 cells/well, was incubated and inflammation (activation of NF-kb) was produced with 0.1 mg/mL of LPS (lipopolysaccharide from E. coli) for 24 hours. We assessed the presence of the extract (10 and 50 mg/L, biologically safe concentrations) for 2 hours at 37º C, before (preventive effect) and after (therapeutic effect) the proinflammatory activation, and the activity of alkaline phosphatase, which is expressed under the control of the NF-kb transcriptional factor, was quantified by colorimetry. The percentage of activity of NF-kb as preventive effect and therapeutic effect was assessed by comparing it to control cultures of cells with LPS and without extract, which are considered 100% of NF-kb. RESULTS: The preventive anti-inflammatory capacity of the extract at 50 mg/L was 25.5% (95% CI: 16.8-34.2) and the therapeutic effect 34.9% (95% CI: 25.3-44.4) for the same concentration, without any significant activity at 10 mg/L. CONCLUSION: An activity of polyphenols extracted from olive pits is shown, both in preventing inflammation and therapeutically eliminating inflammation through inhibition of NF-kB factor previously activated by LPS at concentrations of 50 mg/L of polyphenols, which previously haven been shown to be safe.
