Effect of a cyanobacterial diet on the competition between rotifers: a case study in Lake Albufera of Valencia, Spain
2019
espanolBrachionus havanaensis se distribuye predominantemente en las regiones Neartica y Neotropical. Ahora se encuentra incluso en las regiones Paleartica y Oriental. Durante el verano de 2015, encontramos altas densidades (> 500 ind./l) de esta especie y bajas abundancias de Brachionus angularis en la laguna de la Albufera, donde la cianobacteria (Microcystis aeruginosa) fue dominante en la comunidad de fitoplancton. Nuestra hipotesis fue que la cianobacteria era toxica para B. angularis pero no para B. havanaensis, por lo que este ultimo superaria al primero en presencia de dicha cianobacteria. Para probar la hipotesis, realizamos experimentos de competencia entre estas dos especies de r…
Eating patterns are associated with biomarkers in a selected population of university students and employees.
2011
AbstractThe association between diet and CVD cannot be assigned to a single nutrient, but rather to a set of nutrients and non-nutrients, and eating pattern analyses have become an important tool in investigation of this relationship. Our objective was to investigate eating patterns in relation to nutrient intake and serum concentration of folate, vitamin B12 and TAG in ninety-five healthy adult participants. Dietary information was collected by an FFQ, and eating patterns were obtained by principal components analyses of thirty-three food groups. Three eating patterns were extracted, a sweet eating pattern identified by intakes of cakes, snacks, sugar-sweetened drinks and chocolates; a pru…
Genetic risk profiles for a childhood with severely overweight
2013
Summary What is already known about this subject Genome-wide association studies have identified susceptibility loci, conferring only small effects to obesity. We selected 12 from the most accepted susceptibility genes to overweight, which have been corroborated in different populations and series of thousands of adult individuals. Single-nucleotide polymorphisms variants can have a cumulative effect on common forms of obesity, to create a genetic risk score. What this study adds We concentrated on 109 single-nucleotide polymorphisms (SNPs) located in 12 loci previously reported in association to body mass index at genome-wide significant level, for individuals of European ancestry. To iden…
Influence of the storage conditions on some physicochemical and mycological parameters of honey
1994
The authors studied the changes in yeast and mould counts, pH, free and lactone acidity, colour and sugar composition undergone by honeys with water contents of 169, 188 and 220 g kg-1 on storage at refrigeration temperature (4–7°C), room temperature and 28°C for two years. Of the solid culture media assayed, honey agar and osmophilic medium fostered yeast growth while malt-extract agar and yeast-extract-malt-extract agar allowed for better development of filamentous fungi. The yeasts isolated belonged to the genera Saccharomyces, Schizosaccharomyces and Zygosaccharomyces, while filamentous moulds were of the genera Aspergillus, Penicillium, Fusarium and Alternaria. The honeys studied under…
Biosilica-Based Strategies for Treatment of Osteoporosis and Other Bone Diseases
2011
Osteoporosis is a common disease in later life, which has become a growing public health problem. This degenerative bone disease primarily affects postmenopausal women, but also men may suffer from reduced bone mineral density. The development of prophylactic treatments and medications of osteoporosis has become an urgent issue due to the increasing proportion of the elderly in the population. Apart from medical/hormonal treatments, current strategies for prophylaxis of osteoporosis are primarily based on calcium supplementation as a main constituent of bone hydroxyapatite mineral. Despite previous reports suggesting an essential role in skeletal growth and development, the significance of …
Considerations regarding the alleged association between Herbalife products and cases of hepatotoxicity: a rebuttal.
2014
We thank Dr. K Appelhans et al. for their comments [1] on our paper [2], published online first in April 2012. In our review, we aimed to draw the attention of physicians to the uncontrolled and increasingly alarming use of herbal products and dietary supplements in the general population. In fact, in Italy this phenomenon, though still limited, has rapidly increased over the last few years. Here, use of herbal medicine products has increased to 3.7 %, while in other countries consumption is higher, reaching 20 % in the UK, and 40 % in the USA. Young non-smoking women with a high level of education appear to be the most common consumers [3]. It seems that women use these products more than …
Food for flight: pre-migratory dynamics of the Lesser Kestrel Falco naumanni.
2014
Capsule The post-reproductive stage of Lesser Kestrel is crucial for migratory fuelling and survival. Aims To describe the summer pre-migratory ecology of the Lesser Kestrel in Sicily and review existing data in Southern Europe. Methods We identified the main summer roosts and then made roost counts every ten days from 2010 to 2012. We used case-sensitive modelling procedures to detect biases in counts (generalized linear mixed models), assess the annual population trends from 2005 to 2012 (TRends and Indices for Monitoring); and to model habitat preferences (generalized linear model). We sampled pellets to describe the birds’ diet during the peak month prior to migration. Results We discov…
Short-term impact of a Western diet on the physiology of the peripheral olfactory system
2016
Current feeding behaviors contribute to the epidemic levels of obesity and diabetes observed in Europe and worldwide. Both the quantity and the quality of ingested food are incriminated. Together with other sensory modalities, olfaction is involved in the control of food intake. Olfactory cues can influence eating behaviors, yet the nutritional status and diet can also alter olfactory abilities. Patients with metabolic disorders present impaired olfactory sensitivity which could in turn worsen their eating behaviors.Here we examined the short-term impact of a Western diet enriched in fat and sugar (High Fat High Sugar, HFHS) on the anatomy and physiology of the olfactory epithelium of postn…
Prevention of 7-Ketocholesterol-Induced Overproduction of Reactive Oxygen Species, Mitochondrial Dysfunction and Cell Death with Major Nutrients (Pol…
2020
The brain, which is a cholesterol-rich organ, can be subject to oxidative stress in a variety of pathophysiological conditions, age-related diseases and some rare pathologies. This can lead to the formation of 7-ketocholesterol (7KC), a toxic derivative of cholesterol mainly produced by auto-oxidation. So, preventing the neuronal toxicity of 7KC is an important issue to avoid brain damage. As there are numerous data in favor of the prevention of neurodegeneration by the Mediterranean diet, this study aimed to evaluate the potential of a series of polyphenols (resveratrol, RSV
