New European Discovery of Splachnum pensylvanicum (Bryophyta, Splachnaceae) in Lithuania, with Taxonomic Notes and a Review of Its World Distribution
2021
Splachnum pensylvanicum (Brid.) Grout ex H.A.Crum is recorded for the first time in Lithuania and it is its fourth discovery at a third locality in Europe. It was found for the first time in 2000 in Kamanos mire, the largest peatland complex in the northern part of this East Baltic country. Targeted investigations at this site in 2017 resulted in the discovery of 14 populations and it is apparently the largest and most abundant locality of the species in Europe. Splachnum pensylvanicum is briefly described and illustrated along with some taxonomic notes and a detailed description of its habitat requirements. The global geographical distribution of S. pensylvanicum is reviewed and mapped. It…

Functional characterization of protein variants of the human multidrug transporter ABCC2 by a novel targeted expression system in fibrosarcoma cells
2012
The multidrug resistance-associated protein 2 (MRP2/ABCC2) is involved in the efflux of endogenous and xenobiotic substrates, including several anticancer and antiviral drugs. The functional consequences of ABCC2 protein variants remain inconsistent, which may be due to shortcomings of the in vitro assays used. To study systematically the functional consequences of nonsynonymous ABCC2 variants, we used a novel “Screen and Insert” (ScIn) technology to achieve stable and highly reproducible expression of 13 ABCC2 variants in HT1080 cells. Western blotting revealed lower (30–65%) ABCC2 expression for D333G, R1174H, and R1181L as compared with wild type (WT; 100%), whereas the linked variant V1…
La construcción ideológica de la Restauración en Nueva España (1814-1816)
2020
La vuelta de Fernando VII en 1814 a la península y el golpe de Estado por el que procedió a anular la Constitución de Cádiz no supusieron, a ambos lados del Atlántico, un retorno a la situación previa a la crisis de 1808. Este trabajo examina dicho problema en el virreinato de la Nueva España desde el ámbito de los discursos para el periodo que transcurre entre 1814 y 1816. Para ello se relacionan tres perspectivas. En primer lugar, se confrontan algunos de los distintos proyectos que se plantearon dentro del absolutismo para efectuar la Restauración. Seguidamente, examinamos aquellos componentes teóricos que los intelectuales de la contrarrevolución utilizaron para legitimarla. Este proyec…

Reliģiskais simbolisms Luīzes Erdrikas romānos
2018
Šī pētījuma autors analizē, kādā veidā tiek izmantoti reliģiskie simboli Luīzes Erdrikas tetraloģijā, kas sastāv no romāniem “Mīlas Medicīna”, “Pēdas”, “Biešu Karaliene” un “Bingo Pils”. Reliģisko simbolismu analizēšana viņas romānos ļaus saprast Amerikas indiāņu sarežģīto identitātes veidošanās procesu Amerikas kolonizācijas apstākļos. Pētījuma mērķis ir analizēt, kādos veidos Erdrika izmanto reliģisko simbolismu minētajā tetraloģijā. Pētījuma metodes ir padziļinātā lasīšana, stāstījuma analīze un salīdzinošā interpretatīvā metode, balstoties uz postkoloniālās, Amerikas Indiāņu, stāstījuma analīzes un kulturvēsturiskā diskursa analīzes metodoloģijām. Šajā pētījumā izmantotās metodoloģijas …
Time trends of human papillomavirus types in invasive cervical cancer, from 1940 to 2007.
2013
Contribution over time of human papillomavirus (HPV) types in human cancers has been poorly documented. Such data is fundamental to measure current HPV vaccines impact in the years to come. We estimated the HPV type-specific distribution in a large international series of invasive cervical cancer (ICC) over 70 years prior to vaccination. Paraffin embedded ICC cases diagnosed between 1940 and 2007 were retrieved from eleven countries in Central-South America, Asia and Europe. Included countries reported to have low-medium cervical cancer screening uptake. Information on age at and year of diagnosis was collected from medical records. After histological confirmation, HPV DNA detection was per…
Changes over three decades in outcome and the prognostic influence of age-at-diagnosis in young patients with neuroblastoma: a report from the Intern…
2011
Abstract Purpose Increasing age has been an adverse risk factor in children with neuroblastoma (NB) since the 1970’s, with a 12-month age-at-diagnosis cut-off for treatment stratification. Over the last 30 years, treatment intensity for children >12 months with advanced-stage disease has increased; to investigate if this strategy has improved outcome and/or reduced the prognostic influence of age, we analysed the International Neuroblastoma Risk Group (INRG) database. Patients and methods Data from 11,037 children with NB (1974–2002) from Australia, Europe, Japan, North America. Cox modelling of event-free survival (EFS) tested if the era and prognostic significance of age-of-diagnosis, adj…
Pegylated interferon therapy in chronic hepatitis C: lights and shadows of an innovative treatment
2007
Abstract Pegylated interferon (PEG-IFN) in combination with ribavirin is the standard of treatment for chronic hepatitis C. Several viral and host factors influence the outcome of treatment, such as hepatitis C virus (HCV) genotype, baseline viral load, viral kinetics, race, body weight, advanced liver disease, HIV co-infection, and adherence to therapy. Monitoring the response of HCV to treatment during the early time points (4 weeks or 12 weeks) after initiation of therapy has emerged as a critical tool to predict sustained virologic response (SVR), defined as undetectable serum HCV RNA 24 weeks after the end of therapy. To counterbalance the influence of host and viral factors, treatment…
Prevalence of impacted teeth and supernumerary teeth by radiographic evaluation in three Latin American countries: A cross-sectional study
2021
Background Supernumerary teeth are those that exceed the usual dental formula. There are different classifications depending on their anatomical location, shape and number. The objective of this study was to determine the prevalence of impacted and supernumerary teeth in a sample of panoramic radiographs from three Latin American countries. Material and Methods A retrospective and cross-sectional study with a quantitative approach, in which the radiographic observation and analysis of 2000 panoramic radiographs, provided by different radiological centers in Peru, Colombia and Bolivia were performed. An examiner, specialized in Stomatology and Oral Surgery, carried out the radiographic analy…
