Deploying Genome Editing Tools for Dissecting the Biology of Nut Trees
2019
Walnuts are among the most important nut crops grown in temperate regions of the world. Commercial production in California, and increasingly worldwide, relies on only few clonally grafted scion genotypes, particularly “Chandler,” and more recently clonally propagated disease-resistant rootstocks. Diseases, nematodes, insect pests, abiotic stresses, and other nutritional and environmental factors, can reduce walnut productivity and quality, affecting grower profitability. The California Walnut Breeding Program at UC Davis has developed and released scion cultivars and rootstocks to help address some of these problems. Sequencing of the walnut genome is expected to speed walnut breeding by f…
Metabolic Impacts of Confinement during the COVID-19 Pandemic Due to Modified Diet and Physical Activity Habits
2020
While the detrimental effects of a chronic positive energy balance due to a sedentary lifestyle have been well established, the impacts of a short period of abruptly reduced physical activity and overeating arising from strict confinement due to the COVID-19 pandemic will soon start to emerge. To reasonably anticipate major consequences according to the available evidence, we hereby review the literature for studies that have explored the health impacts of several weeks of a reduction in physical activity and daily step-count combined with modified eating habits. These studies identify as main metabolic consequences increases in insulin resistance, total body fat, abdominal fat and inflamma…
Anti-proliferative effect of main dietary phytosterols and β-cryptoxanthin alone or combined in human colon cancer Caco-2 cells through cytosolic Ca+…
2015
β-cryptoxanthin (β-Cx) and phytosterols (Ps) have potential against different cancer types, including colon cancer. However, their combined action has not been reported so far. Human colon cancer Caco-2 cells were treated 24 h with β-Cx and/or main dietary Ps (β-sitosterol, campesterol and stigmasterol), alone or in combination, at concentrations compatible with physiological human serum levels. A decrease in cell viability due to apoptosis (rise in sub-G1 population and exposure of membrane phosphatidylserine) was accompanied with dephosphorylation of BAD, mitochondrial depolarization and caspase 3-dependent PARP cleavage, with intracellular Ca2+ influx and increase of RONS levels as initi…
Aesthetics of Nutrition, Ethics of Animality: the Packaging of Vegan and Vegetarian Products in the Italian Organised Distribution Market
2018
The topic of this paper concerns the packaging of vegan and vegetarian products in the Italian organised distribution market. Large-scale organised distribution and vegetarianism's choice of packaging is related to current dietary trends which, as is often the case with eating choices and habits, intertwine as they massively spread. Which are the visual and verbal strategies that are adopted to give meaning, in the Italian culinary landscape, to vegan and vegetarian foods sold through large-scale distribution? The aim is to outline, through the methodology of Semiotics, the sensorial mechanisms and cultural grids that shape this food universe, and the way it interacts with other categories …
Lifetime total and beverage specific - alcohol intake and prostate cancer risk: a case-control study
2004
Abstract Background We investigated lifetime alcohol consumption and prostate cancer risk in a case-control study conducted in Buffalo, NY (1998–2001). Methods The study included 88 men, aged 45 to 85 years with incident, histologically-confirmed prostate cancer and 272 controls. We conducted extensive in-person interviews regarding lifetime alcohol consumption and other epidemiologic data. Results Prostate cancer risk was not associated with lifetime intake of total and beverage specific ethanol. In addition we found no association with number of drinks per day (average drinks per day over the lifetime) or drinks per drinking day (average drinks per day on drinking days only over the lifet…
Absence Ochratoxin A in soy sauce
2004
A method is described for the determination of ochratoxin A (OTA) in soy sauce using phosphate-buffered saline (PBS) extraction, an immunoaffinity clean-up, a liquid chromatographic determination with fluorescence detection (LC-FD) and confirmation with LC-FD after methylation of OTA. Recoveries of OTA spiked to soy sauce samples at 0.25 ng/ml level were 90% with relative standard deviations of 4%. The limit of detection was 0.01 ng/ml for OTA using the proposed method. Furthermore, the proposed method was applied to 60 soy sauce samples from China and Japan and none of them were found to contain OTA.
BMI-BFMNU: A structural index linked to fat mass
2021
Abstract Introduction: Body mass index (BMI) provides little information on body composition. For example, two people with the same BMI might have different body compositions. In this sense, the development of a new BMI able to provide body composition information is of clinical and scientific interest. The aim of the study was to suggest a new modified BMI formula. Material and Methods: A total of 108 subject, females 56 and males 52, 0-73 years old, in various physiopathological conditions were evaluated. Data were collected and processed by a program that through anthropometric measurements calculates classic BMI, volume, surface, V/S (that we can defined like a body-thickness “pse…
Estudio del estado nutricional de estudiantes de educación primaria y secundaria de la provincia de Valencia y su relación con la adherencia a la Die…
2014
Introducción: La obesidad infantil está alcanzando cifras muy elevadas entre la población infantil española favoreciendo la obesidad en la edad adulta. El objetivo del presente estudio es conocer el estado nutricional de estudiantes de seis colegios de la provincia de Valencia y su grado de adhesión a la Dieta Mediterránea (DM).Material y métodos: Estudio transversal en el que participaron 777 estudiantes, 49,9% eran chicos y 50,1% chicas con edades comprendidas entre 8 y 16 años. Se determinó el peso y la altura de cada participante y se calculó el Índice de Masa Corporal (IMC). A partir del IMC se calculó el Z-score. Para determinar el grado de adhesión a la DM se utilizó el test KidMed.R…
Mirando hacia atrás para vislumbrar el futuro de la Revista Española de Nutrición Humana y Dietética: líneas estratégicas 2017
2016
Se realiza una valoración de los logros alcanzados por la revista RENHyD en estos últimos años, así como por aquellas acciones desarrolladas que han conllevado resultados no satisfactorios. Las lecciones aprendidas, en este recorrido, han ayudado a definir las líneas estratégicas a desarrollar en este próximo año. Estas líneas que se presentan tienen por finalidad incrementar la calidad formal de la revista de acuerdo con los estándares internacionales, lo cual posibilitará la indexación en más bases de datos bibliográficas de ámbito internacional.
