Changes in surface EMG assessed by discrete wavelet transform during maximal isometric voluntary contractions following supramaximal cycling
(CIENCIAS, 2013)To better understand characteristics of neuromuscular fatigue in supramaximal cycling exercise, this study examined changes in surface electromyography (sEMG) frequency during maximal voluntary isometric contractions (MVC) ... -
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 ... -
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 ... -
Comparative study of mouthparts of three species of horse flies of the tribe Pangoniini of Chilean distribution (Diptera: Tabanidae)
(CIENCIAS, 2004)Mouthparts of 3 species representing Esenbeckia Rondani, Protodasyapha Enderlein, and Veprius Rondani of the tribe Pangoniini were examined by scanning electron microscopy (SEM), and their structures are herein described. ... -
Complete genome sequence of the salmonella enterica serovar enteritidis bacteriophages fSE1C and fSE4C isolated from food matrices
(CIENCIAS, 2017)Salmonella enterica serovar Enteritidis is one of the most common causes of Salmonellosis worldwide. Utilization of bacteriophages as prophylactic agents is a practical solution to prevent Salmonellosis in ready-to-eat ... -
Biofilm formation of mucosa-associated methanoarchaeal strains
(CIENCIAS, 2014)Although in nature most microorganisms are known to occur predominantly in consortia or biofilms, data on archaeal biofilm formation are in general scarce. Here, the ability of three methanoarchaeal strains, Methanobrevibacter ... -
Biogeographic origin and thermal acclimation interact to determine survival and hsp90 expression in Drosophila species submitted to thermal stress
(CIENCIAS, 2012)The relationship between thermal tolerance and environmental conditions has been extensively studied in Drosophila. However, comparisons of thermal tolerance of laboratory-bred flies derived from distinct geographic locations ... -
Bidding behavior in the Chilean electricity market
(HUMANIDADES, 2015)Contracts in power markets are usually obscure. From recently public auctions of long-term supply contracts we can obtain information on how contract prices are determined. To understand generators' bidding behavior, this ... -
Beef production from dairy bulls under two different production systems and its effect on the fatty acid profile and beef quality.
(CIENCIAS, 2014)Bulls in dairy production are usually slaughtered at an early age to avoid production problems and unnecessary costs. However, the animals could be a source of additional income and better quality meat. The objective of ... -
Can an LED-laser hybrid light help to decrease hydrogen peroxide concentration while maintaining effectiveness in teeth bleaching?
(CIENCIAS, 2015)The aim of this study was to compare the bleaching efficacy of 35% hydrogen peroxide and 15% hydrogen peroxide with nitrogen-doped titanium dioxide catalysed by an LED-laser hybrid light. We studied 70 patients randomized ... -
Caloric restriction and aging stem cells: The stick and the carrot?
(CIENCIAS, 2014)Adult tissue stem cells have the ability to adjust to environmental changes and affect also the proliferation of neighboring cells, with important consequences on tissue maintenance and regeneration. Stem cell renewal and ... -
Azadinium poporum from the Argentine Continental Shelf, Southwestern Atlantic, produces azaspiracid-2 and azaspiracid-2 phosphate
(CIENCIAS, 2016)The marine dinophycean genus Azadinium has been identified as the primary source of azaspiracids (AZA), a group of lipophilic phycotoxins known to accumulate in shellfish. Blooms of Azadinium in the southern Atlantic off ... -
Biceps Brachii Muscle Innervation Zone Location in Healthy Subjects Using High-Density Surface Electromyography.
(CIENCIAS, 2011)Entre las secuelas de lesiones del Sistema Nervioso Central se encuentra la espasticidad, la cual es de difícil manejo terapéutico. Los tratamientos actuales de la espasticidad consideran la administración de la toxina ... -
Bursting the unfolded protein response accelerates axonal regeneration
(CIENCIAS, 2016)Peripheral neuropathies refer to a group of conditions in which the peripheral nervous system (PNS) is damaged. These pathological state are are associated with weakness, pain, and loss of motor and sensory control. More ... -
Antifungal activity of low molecular weight chitosan against clinical isolates of Candida spp.
(CIENCIAS, 2010)Chitosan is a natural polymer derived from chitin, a structural component of fungi, insects and shrimp, which exerts antimicrobial effects against bacteria and fungi. The aim of this study was to investigate the in vitro ... -
