Honeybee health in South America
(CIENCIAS, 2016)
Honeybees are essential components to modern agriculture and economy. However, a continuous increase in cases of colony losses and colony depopulation are being reported worldwide. This critical situation has put the fragile ...
A Novel Method to Predict Genomic Islands Based on Mean Shift Clustering Algorithm
(CIENCIAS, 2016)
Genomic Islands (GIs) are regions of bacterial genomes that are acquired from other organisms by the phenomenon of horizontal transfer. These regions are often responsible for many important acquired adaptations of the ...
New and interesting chaetothyrialean fungi from Spain
(CIENCIAS, 2016)
In the course of taxonomic studies on saprobic microfungi from Spain, several slow-growing, dematiaceous hyphomycetes were isolated from soil, submerged plant material and river sediments. Sixteen of these strains were ...
Mitochondria in the Aging Muscles of Flies and Mice: New Perspectives for Old Characters
(CIENCIAS, 2016)
Sarcopenia is the loss of muscle mass accompanied by a decrease in muscle strength and resistance and is the main cause of disability among the elderly. Muscle loss begins long before there is any clear physical impact in ...
Influence of lipopolysaccharide outer-core in the intrinsic resistance to antimicrobial peptides and virulence in Edwardsiella ictaluri
(CIENCIAS, 2016)
The genus Edwardsiella consists of bacteria with an intrinsic resistance to cyclic cationic antimicrobial peptides (CAMPs). Edwardsiella ictaluri, a pathogen of the catfish (Ictalurus punctatus) and the causative agent of ...
Commentary: XBP-1 Is a Cell-Nonautonomous Regulator of Stress Resistance and Longevity
(CIENCIAS, 2016)
The life expectancy in the world's population is increasing, highlighting the need of better understanding of the cellular and molecular pathways that drive the aging process. Because aging is the major risk factor to ...
Frecuencia de displasia epitelial y carcinoma escamoso en mucosa oral y orofaríngea en Chile, entre los años 1990 y 2009
(CIENCIAS, 2016)
Background: Oral cancer in Chile corresponds approximately to 1.6% of all cancer cases. There are few studies about oral epithelial dysplasia and oral squamous cell carcinoma in the Chilean population. Aim: To determine ...
Molecular detection of vector-borne pathogens in wild and domestic carnivores and their ticks at the human-wildlife interface
(CIENCIAS, 2016)
Urbanization of natural areas is considered one of the causes of the current apparent emergence of infectious diseases. Carnivores are among the species that adapt well to urban and periurban environments, facilitating ...
Impact of Dietary Lipids on Colonic Function and Microbiota: An Experimental Approach Involving Orlistat-Induced Fat Malabsorption in Human Volunteers
(CIENCIAS, 2016)
OBJECTIVES: High-fat diets alter gut microbiota and barrier function, inducing metabolic endotoxemia and low-grade inflammation. Whether these effects are due to the high dietary lipid content or to the concomitant decrease ...
Variation in coastal Antarctic microbial community composition at sub-mesoscale: spatial distance or environmental filtering?
(CIENCIAS, 2016)
Spatial environmental heterogeneity influences diversity of organisms at different scales. Environmental filtering suggests that local environmental conditions provide habitat-specific scenarios for niche requirements, ...
