Infection and exposure to vector-borne pathogens in rural dogs and their ticks, Uganda
(CIENCIAS, 2015)Background: In rural parts of Africa, dogs live in close association with humans and livestock, roam freely, and usually do not receive prophylactic measures. Thus, they are a source of infectious disease for humans and ... -
Recent changes in total ice volume on Volcan Villarrica, Southern Chile
(CIENCIAS, 2015)Results obtained by the first intensive airborne surveys carried out at Volcan Villarrica (39 degrees S) in Southern Chile, are presented. These campaigns included the use of a scanner laser system, for detecting the glacier ... -
Characterization of bacterial, archaeal and eukaryote symbionts from antarctic sponges reveals a high diversity at a three-domain level and a particular signature for this ecosystem
(CIENCIAS, 2015)Sponge-associated microbial communities include members from the three domains of life. In the case of bacteria, they are diverse, host specific and different from the surrounding seawater. However, little is known about ... -
Can repair increase the longevity of composite resins? Results of a 10-year clinical trial
(CIENCIAS, 2015)Objectives: The aim of this double-blind clinical trial was to assess the longevity of repairs to localized clinical defects in composite resin restorations that were initially planned to be treated with a restoration ... -
Sealing Composite With Defective Margins, Good Care or Over Treatment? Results of a 10-year Clinical Trial
(CIENCIAS, 2015)PURPOSE: The objective of this study was to clinically evaluate sealed composite restorations after 10 years and compare their behavior with respect to controls. METHODS AND MATERIALS: The cohort consisted of 20 patients ... -
Phylogeny of Sarocladium (Hypocreales)
(CIENCIAS, 2015)The circumscription of the genus Acremonium (Hypocreales) was recently reviewed on the basis of a DNA phylogenetic study. Several species were subsequently transferred to Sarocladium, but the relationships between both ... -
Clinical, imaging and genetic analysis of double bilateral radix entomolaris
(CIENCIAS, 2015)Background: Anatomy describes that first mandibular molars have two roots: 1 mesial, with 2 root canals, and 1 distal, with 1 root canal. The presence of three roots in these teeth is uncommon. Root anatomical variations ... -
MUC1/SEC and MUC1/Y overexpression is associated with inflammation in Sjogren's syndrome
(CIENCIAS, 2015)Objectives: To evaluate the expression and localization of MUC1/SEC and MUC1/Y isoforms in labial salivary glands (LSG) from Sjögren's syndrome patients (SS patients), as well as their in vitro expression induced by ... -
Identification of Thiotetronic Acid Antibiotic Biosynthetic Pathways by Target-directed Genome Mining
(CIENCIAS, 2015)Recent genome sequencing efforts have led to the rapid accumulation of uncharacterized or "orphaned" secondary metabolic biosynthesis gene clusters (BGCs) in public databases. This increase in DNA-sequenced big data has ... -
Colonización por dermatofitos en cuyes (Cavia porcellus) mantenidos en tiendas de mascotas: Primer reporte en Santiago de Chile
(CIENCIAS, 2015)Antecedentes: Los dermatofitos son hongos patógenos que pueden formar parte de la microbiota de mamíferos como perros, gatos y roedores, que pueden ser fuente y vehículo de transmisión a otros hospederos, incluyendo al ... -
Recombinant lactic acid bacteria as delivery vectors of heterologous antigens: the future of vaccination?
(CIENCIAS, 2015)Lactic acid bacteria (LABs) are good candidates for the development of new oral vaccines and are attractive alternatives to attenuated pathogens. This review focuses on the use of wild-type and recombinant lactococci and ... -
Human Infections with Pseudoterranova cattani Nematodes, Chile
(CIENCIAS, 2015)To the Editor: Anisakidosis is an emerging foodborne zoonosis caused by nematode larvae of the Anisakinae subfamily, which includes the genera Anisakis, Pseudoterranova, and Contracecum (1). In natural cycles, anisakid ... -
Extensive Identification of Bacterial Riboflavin Transporters and Their Distribution across Bacterial Species
(CIENCIAS, 2015)Riboflavin, the precursor for the cofactors flavin mononucleotide (FMN) and flavin adenine dinucleotide, is an essential metabolite in all organisms. While the functions for de novo riboflavin biosynthesis and riboflavin ... -
Déficit adquirido de factor X en leucemia mielomonocítica crónica: reporte de un caso
(CIENCIAS, 2015)Se han descrito múltiples síndromes hemorragíparos asociados a patologías hemato-oncológicas. Algunos casos son clásicos y característicos como la coagulopatía asociada a la leucemia promielocítica aguda1, y otros se pueden ... -
Eukaryotic picophytoplankton community response to copper enrichment in a metal-perturbed coastal environment
(CIENCIAS, 2015)Copper is an essential micronutrient, especially for photosynthetic organisms, but can be toxic at high concentrations. In the past years, coastal waters have been exposed to an increase in copper concentration due to ... -
Intratask Variability As a Correlate for DRD4 and SLC6A3 Variants: A Pilot Study in ADHD
(CIENCIAS, 2015)Behavioral variability may be an ADHD key feature. Currently used ex-Gaussian/Fast Fourier Transform analyses characterize general distribution and oscillatory/rhythmic components of performance but are unable to demonstrate ... -
