(2011)The onshore distribution and abundance of the South American sea lion Otaria flavescens along the central Chilean coast was estimated during the period January-February 2007. Additionally, changes in population abundance ...
-
(2011)Objective: To determine the prevalence of voiding dysfunction (VD) in patients with persistent vulvovaginitis (PVV), and to evaluate the clinical response of PVV in the treatment of VD. Patients and Methods: Girls four ...
-
(2011)Human T-cell leukemia virus type I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a neurodegenerative disease characterized by selective loss of axons and myelin in the corticospinal tracts. This ...
-
(2011)To address elements that might uniquely characterize EGR-1 mediated signaling, the expression of two transcription factors, namely, nuclear factor kappa B (NF-κB) and activator protein-1 (AP-1) were studied. PC-3 and LNCaP ...
-
(2011)One of the capabilities developed by bacteria is the ability to gain large fragments of DNA from other bacteria or to lose portions of their own genomes. Among these exchangeable fragments are the genomic islands (GIs). ...
-
(2011)Experimental evidence shows that the mechanism of pore formation by actinoporins is a multistep process, involving binding of the water-soluble monomer to the membrane and subsequent oligomerization on the membrane surface, ...
-
(2011)Antibiotic therapy improves the outcome of severe sepsis and septic shock, however pharmacokinetic properties are altered in this scenario. Amikacin (AMK) is an option to treat community or nosocomial infections, although ...
-
(2011)During long-term potentiation (LTP), synapses undergo stable changes in synaptic strength. The molecular memory processes that maintain strength have not been identified. One hypothesis is that the complex formed by the ...
-
(Elsevier Inc., 2011)Chronic hyperandrogenism alters the peroxisome proliferator-activated receptor γ (PPARγ) pathway in the uterine tissue of prepubertal mice. The gene and protein expression of PPARγ is not modified, but the gene and protein ...
-
(2011)The skin and nails are commonly involved in rheumatic conditions, both by the primary disease and/or long-term immunosuppressive treatments. These superficial affections may also imply a worsening of the quality of life ...
-
(Taylor and Francis Inc., 2011)Several neurodegenerative diseases share a common neuropathology, primarily featuring the presence of abnormal protein inclusions in the brain containing specific misfolded proteins. Strategies to decrease the load of ...
-
(2011)Background: Human papillomavirus (HPV) and Epstein Barr virus (EBV) have been found in breast carcinomas (BCs) around the world. In this study, fifty-five BCs from Chile were analyzed for HPV and EBV presence. In addition, ...
-
Toxicological Evaluation of Realistic Emission Source Aerosols (TERESA): Introduction and overview (2011)Determining the health impacts of sources and components of fine particulate matter (PM2.5) is an important scientific goal. PM2.5 is a complex mixture of inorganic and organic constituents that are likely to differ in ...
-
(2011)Background: Oxidative stress associated with 3,3′,5-triiodo-l- thyronine (T3)-induced calorigenesis upregulates the hepatic expression of mediators of cytoprotective mechanisms. The aim of this study was to evaluate the ...
-
(2011)The stability of an apple peel polyphenol extract (APPE) with powerful antioxidant activity was evaluated under acidic conditions in vitro, and its protective effect against gastrointestinal damage was investigated in rats ...
-
(2011)Background: In preterm infants at risk for RDS, reintubation following surfactant replacement therapy and successful extubation may be associated with poor clinical outcomes. Methods: Initial extubation, reintubation, ...
-
(2011)Hsp90 is a molecular chaperone involved in the stabilization of many oncoproteins that are required for the acquisition and maintenance of the so-called six major hallmarks of cancer cells. Various strategies have, therefore, ...
-
(2011)This paper undertakes a quantitative analysis of the socioeconomic and environmental impacts of different trade agreements for Chile. A dynamic general equilibrium model is used to compare the consequences of unilateral ...
-
(2011)A decrease in the expression of E-cadherin and β-catenin, paralleling the loss of adherens junction complex, was observed in MCF7 cells exposed for longer than 48 h to 2 μM27-hydroxycholesterol (27OHC), indicating an ...
-
(2011)Ski is a negative regulator of the transforming growth factor-β and other signalling pathways. The absence of SKI in mouse fibroblasts leads to chromosome segregation defects and genomic instability, suggesting a role for ...
