Validation of the Grit Scale and the Treatment Self-Regulation Questionnaire (TSRQ) in the Mexican context
2019
espanolResumen La ausencia de instrumentos validos para medir variables relacionadas con las conductas saludables en Mexico, nos lleva al objetivo de adaptar y validar al idioma espanol hablado en Mexico la escala Grit y el cuestionario de autorregulacion del tratamiento (TSRQ) de la dieta, y explorar la relacion entre el Grit y la motivacion hacia la alimentacion saludable como evidencia de validez. 353 adultos del estado de Nuevo Leon respondieron a la escala Grit adaptada al espanol conformada por 12 items distribuidos en dos factores (consistencia del interes y perseverancia del esfuerzo) y al TSRQ adaptada al espanol compuesto por 15 items en tres factores (motivacion autonoma, motivac…
Influence of a high fat diet during adolescence on the reinforcing effects of cocaine and alcohol
2017
RESUMEN La adolescencia es un período de especial vulnerabilidad en el desarrollo del ser humano, en el que se dan grandes cambios a nivel estructural y funcional (Spear, 2000; Chambers et al., 2003). En esta etapa de gran vulnerabilidad, los jóvenes muestran trastornos de la alimentación, consumo de sustancias, búsqueda de sensaciones y conductas de riesgo (Bava and Tapert, 2010). Actualmente, el consumo excesivo de comida especialmente rica en azúcares y grasas, se ha convertido en un serio problema para nuestra sociedad, habiéndose producido un incremento en las tasas de obesidad a nivel mundial que afecta particularmente a la población adolescente. La alimentación está regulada tanto po…
Dietary acid load and renal function have varying effects on blood acid-base status and exercise performance across age and gender
2017
Diet composition influences acid-base status of the body. This may become more relevant as renal functional capacity declines with aging. We examined the effects of low (LD) versus high dietary acid load (HD) on blood acid-base status and exercise performance. Participants included 22 adolescents, 33 young adults (YA), and 33 elderly (EL), who followed a 7-day LD and HD in a randomized order. At the end of both diet periods the subjects performed a cycle ergometer test (3 × 10 min at 35%, 55%, 75%, and (except EL) until exhaustion at 100% of maximal oxygen uptake). At the beginning of and after the diet periods, blood samples were collected at rest and after all workloads. Oxygen uptake, re…
Green biotechnology for valorisation of residual biomasses in nutraceutic sector: Characterization and extraction of bioactive compounds from grape p…
2019
The grape pomace (GP) is an important by-product of winemaking, accounting for about 13-25% of the grapes processed. The aim of this work was to investigate the nutritional and antioxidant composition of GP obtained from Nero d’Avola (NA) grape, one of the most important indigenous varieties in Italy, in order to verify application in nutraceutics. Seeds and skin of the GP were studied for their nutritional and antioxidants composition, fatty acid and polyphenols profile, bioactives properties in vitro, by gravimetric, spectrophotometric and chromatographic techniques. The results showed that NAGP seeds are rich in the beneficial polyunsaturated fatty acids and that the polyphenols extracte…
Probiotics in the prevention and treatment of atopic dermatitis
2020
The use of probiotic supplements might change the composition of the intestinal flora of children, subsequently modulating the immune system's reactivity. The effects of probiotic administration for the prevention/treatment of allergic diseases and atopic dermatitis, in particular, are still so controversial that no definitive recommendation can be made at this stage. Differences in strain specificity, timing, and length of administration all contribute to diversifying the conclusions of this review.
Dietary polyphenols as antidiabetic agents: Advances and opportunities
2020
Abstract Dietary polyphenols have been widely investigated as antidiabetic agents in cell, animals, human study, and clinical trial. The number of publication (Indexed by Web of Science) on “polyphenols and diabetes” significantly increased since 2010. This review highlights the advances and opportunities of dietary polyphenols as antidiabetic agents. Dietary polyphenols prevent and manage Type 2 diabetes mellitus via the insulin‐dependent approaches, for instance, protection of pancreatic islet β‐cell, reduction of β‐cell apoptosis, promotion of β‐cell proliferation, attenuation of oxidative stress, activation of insulin signaling, and stimulation of pancreas to secrete insulin, as well as…
Gut microbiota changes in rainbow trout, Oncorhynchus mykiss (Walbaum), during organic acid feed supplementation and Yersinia ruckeri infection
2013
Gut microbiota (GM) composition of vertebrates are considered to influence health parameters including immunological parameters in the host but knowledge of these issues in fish are sparse. We have performed a 45 day experimental study elucidating effects of dietary supplementation of organic acids (Mera Cid) and immunostimulants on the GM composition of rainbow trout Oncorhynchus mykiss (Walbaum) and investigated its association with blood parameters and disease resistance (against enteric red mouth disease (ERM) caused the bacterium Yersinia ruckeri). A total of 640 fish received either 1) basic fish feed without organic acids or immunostimulants, 2) fish feed with immunostimulants (β6glu…
Comparison of Body Composition and Energy Intake of Young Female Ballet Dancers and Ordinary School Girls
2017
Abstract The aim of this study is to assess body fat level, energy and nutrient intake of adolescent ballet dancers and to compare these results with those of adolescents from ordinary school. Participants included 39 ballet dancers and 70 adolescents from ordinary school. Body composition was measured using a multi-frequency 8-polar bioelectrical impedance leg-to-hand analyser (X-Scan Plus II, Korea). Dietary intakes were assessed using a three-day estimated food record. Nutritional intake was calculated using the Nutri Survey software. Ballet dancers were slightly shorter, lighter, with less fat and fat-free mass compared to girls from ordinary school. 51.3% (95% CI 35.59 to 66.97) of bal…
Effect of Combining Impact-Aerobic and Strength Exercise, and Dietary Habits on Body Composition in Breast Cancer Survivors Treated with Aromatase In…
2023
This study examines both the effect of a twice-weekly combined exercise—1 h session of strength and 1 h session of impact-aerobic—on body composition and dietary habits after one year of treatment with aromatase inhibitors (AI) in breast cancer survivors. Overall, forty-three postmenopausal women with a BMI ≤ 35 kg/m2, breast cancer survivors treated with AI, were randomized into two groups: a control group (CG) (n = 22) and a training group (IG) (n = 21). Body composition, i.e., abdominal, visceral, and subcutaneous adipose tissue) was measured by magnetic resonance. In addition, some questionnaires were used to gather dietary data and to measure adherence to the Mediterranean diet. After …
Explanations for use of dietary- and muscle enhancing dietary supplements among university students: a national cross-sectional study.
2022
Abstract Background Use of dietary supplements (DS) and muscle enhancing dietary supplements (MEDS) is frequent among students despite the lack of evidence of effects and health risks related to consumption. We need to increase our understanding of students’ motivation, examine potential gender differences, and explore explanatory factors, to address preventive measures related to use. Therefore, this study aimed to explore the frequency of, and the reasons for, DS use among university students, as well as explanatory factors for use of MEDS. Method Male and female students from nine Norwegian universities participated in this cross-sectional study. Participants responded to questions about…
