Efectos de los coadyuvantes tecnológicos y técnicas sobre la extractabilidad e índices de calidad del aceite de oliva

This study was conducted to investigate the effects of processing aids and techniques such as talcum powder (2% w/w), calcium carbonate (2% w/w), warm water dipping (45 °C), combined treatment (warm water dipping+2% calcium carbonate) and control (without adding processing aid) on extractability and quality of ‘Tarom 7’ olive oil as randomized complete block design with three replicates. The results showed that there were no significant differences in the carotenoid content, K232, fatty acid profile or the Cox’s value in the oil obtained from untreated and treated fruits with processing aids. The highest chlorophyll content (0.84 mg/kg), total phenolic content (236.94 mg/kg), paste extractability (8.5%) and the lowest peroxide values (0.32 meqO2/kg), K270 (0.38) were obtained from the oil extracted with 2% talc powder. According to the results, it can be suggested that the 2% talc powder treatment could have a positive effect on olive oil quality and paste extractability.Este estudio se llevó a cabo para investigar los efectos de los coadyuvantes del procesamiento y técnicas, como talco (2 % p/p), carbonato de calcio (2 % p/p), inmersión en agua tibia (45 °C), tratamiento combinado (inmersión en agua tibia + carbonato de calcio al 2%) y control (sin adición de coadyuvante) sobre la extractabilidad y calidad del aceite de oliva ‘Tarom 7’ en un diseño de bloques completos al azar con tres repeticiones. Los resultados mostraron que no hubo diferencias significativas en el contenido de carotenoides, K232, perfil de ácidos grasos y el valor de Cox del aceite obtenido de frutos no tratados y tratados con coadyuvantes de procesamiento. El mayor contenido de clorofila (0,84 mg/kg), contenido de fenoles totales (236,94 mg/kg), extractabilidad de la pasta (8,5%) y los valores más bajos de peróxidos (0,32 meqO2/kg) y K270 (0,38) se obtuvieron para el aceite extraído con 2 % de talco. De acuerdo con los resultados, se puede sugerir que el tratamiento con talco al 2% podría tener un efecto positivo sobre la calidad del aceite de oliva y la extractabilidad de la pasta. &nbsp

The Health Initiative Program for Kids (HIP Kids): Effects of a 1-Year Multidisciplinary Lifestyle Intervention on Adiposity and Quality of Life in Obese Children and Adolescents -- A Longitudinal Pilot Intervention Study

BACKGROUND: Though recent data suggest that multidisciplinary outpatient interventions can have a positive effect on childhood obesity, it is still unclear which program components are most beneficial and how they affect quality of life (QoL). The aim of this study was to determine if a 1-year multidisciplinary, family-centered outpatient intervention based on social cognitive theory would be effective in (i) preventing further increases in BMI and BMI z-score, and (ii) improving QoL in obese children and adolescents. METHODS: Obese children and adolescents 8-17 years of age and their families participated in this 1-year longitudinal pilot intervention study. The intervention consisted of fifteen 90-minute educational sessions led by a dietitian, exercise specialist, and social worker. Anthropometric measures, body composition, and QoL (Pediatric Quality of Life Inventory 4.0), were assessed at baseline, 3 months, and 12 months. Laboratory values were measured at baseline and 12 months. The primary outcome measures were change in BMI and BMI z-score, secondary outcome measures included change in QoL and body composition. A paired sample t-test was used to assess within-group differences and 95% confidence intervals were reported for the mean differences. RESULTS: 42 obese children and adolescents (21 girls) completed the 1-year intervention (mean age 12.8 ± 3.14 years). Mean baseline BMI was 31.96 ± 5.94 kg/m(2) and BMI z-score was +2.19 ± 0.34. Baseline QoL (self-assessments and parental assessments) was impaired: mean baseline scores were 74.5 ± 16.5 and 63.7 ± 19.4 for physical functioning and 69.0 ± 14.9 and 64.0 ± 18.3 for emotional functioning, respectively. At 12 months, BMI z-score had decreased (-0.07 ± 0.11, 95% CI: -0.11 to -0.04). BMI (0.80 ± 1.57 kg/m(2), 95% CI 0.31 to 1.29) and fat-free mass (4.02 ± 6.27 kg, 95% CI 1.90 to 6.14) increased, but % body fat and waist circumference did not. Both the parent-reported physical (11.3 ± 19.2, 95% CI 4.7 to 17.9) and emotional (7.7 ± 15.7, 95% CI 2.3 to 13.0) functioning QoL scores and the children\u27s self-reported physical (5.3 ± 17.1, 95% CI 0.5 to 11.1) and emotional (7.9 ± 14.3, 95% CI 3.2 to 12.7) functioning scores significantly improved. CONCLUSIONS: Following a 1-year intervention, the participants\u27 BMI z-scores and QoL improved, while other adiposity-related measures of body composition remained unchanged.

Medium-Term Complications Associated With Coronary Artery Aneurysms After Kawasaki Disease: A Study From the International Kawasaki Disease Registry.

Background Coronary artery aneurysms (CAAs) may occur after Kawasaki disease (KD) and lead to important morbidity and mortality. As CAA in patients with KD are rare and heterogeneous lesions, prognostication and risk stratification are difficult. We sought to derive the cumulative risk and associated factors for cardiovascular complications in patients with CAAs after KD. Methods and Results A 34-institution international registry of 1651 patients with KD who had CAAs (maximum CA

Study of Todebin dam reservoir in Zanjan province in order to aquaculture possibility

The Todebin dam reservoir has been constructed in central part of Abhar in the Zanjan province which has been studied with aquaculture purpose. This study was conducted on biotic and abiotic factors. The plankton, benthos and fishes were identified and the parasitology and bacteriology studies were performed on the lake fishes. Then the fisheries potential of the lake was calculated in respect of final fish farming amount and the fish releasing. The results showed the Bacillariophyta was dominated ِduring the study. the highest abundance of phytoplankton was between 2.1 and 12.5 million cells.l^-1 in the upper layer of lake as compared with the lower layer. The genus Cyclotella and Dinobryon belong to phytoplankton and Keratella and Polyathera belong to zooplankton were dominanted abundance. The mean biomass of benthos was varied from 5.5 to 29.5 g.m -2 and the Chironomidae had the most abundance. The ichtiology survey showed the presence of four cultured species and the Goldfish. The hydro-chemical results indicated no restriction for aquaculture activity. The oxygen average was more than 8 mg/l. The average of phosphate, nitrogen and hardness were measured 0.09±0.04, 2±0.8 and 237±94.5 mg/l., respectively. For the most hydrochemical factores, the values were significantly different between upper and bottom layers of the lake. The oxygen production and Chl-a amount were measured about 0.73 mg/l. and 7/03 µg/l., respectively. According to climatic restrictions, the cold fish culture is preferred than to culture of warm fishes. While the natural capacity of the lake was about 5 tones to warm fish culture, the fish production of trout was estimated about 40 tones. This volume will be available during four months periods and twice a year

The incidence of major cardiovascular events relied coronary vessels after angioplasty and stent types complications

Background: Cardiovascular diseases alone have become the leading cause of death worldwide. One of the treatment methods cardiovascular disease is angioplasty. This study aimed to investigate the clinical results after coronary artery angioplasty, based on the incidence of major cardiovascular events with emphasis on stent types. Methods: In this retrospective cross-sectional study, the prevalence of risk factors (age, history of previous illness and previous surgery) was assessed by using a case file for patients undergoing coronary angioplasty and stent placement during the years 2006 to 2016 and found during the follow-up. The place of the study was the Imam Ali Hospital's educational center affiliated to Kermanshah University of Medical Sciences, Iran, from July to September 2017. Results: In this study, 1188 patients undergone to stent containing 909 non-drug stents, 504 sirolimus-eluting stents and 316 paclitaxel-eluting stents. Patients were followed-up one to five years. During follow-up, 98 patients involved major cardiovascular events, six cases involved with death and 91 patients involved with myocardial infarction. 1729 of patients undergone angioplasty and during follow-up, 91 patients had stent restenosis. In this study stent restenosis showed the highest correlation with the incidence of major cardiovascular events. With a view to stent type in lesions with stent restenosis, 61.7 was in non-drug stent, 23.5 was in paclitaxel-eluting stent and 14.8 was in sirolimus-eluting stent. This study also showed that despite the superiority of sirolimus-stained stents, there was no difference between paclitaxel-stained stents and non-drug stents in clinical outcomes and restenosis. Conclusion: The results showed that the syringes impregnated with sirolimus have better quality. Also, stents that have a smaller diameter or need dilatation in the procedure have a worse prognosis and cause more complications in the patient. © 2018, Tehran University of Medical Sciences.
