What does the translator do when she takes a moment? : scriptlog-aided analysis of long pauses and dictionary use in a translation process

2010

Käännösprosessin tutkiminen on viime vuosina siirtynyt yhä enemmän lopputekstin tutkimisesta itse prosessin eri osien ja piirteiden tutkimukseen. Tauot ovat yksi tämän prosessin eniten tutkituista piirteistä, mutta tähän asti tutkimukset ovat keskittyneet lähinnä kahden tai maksimissaan viiden sekunnin pituisten taukojen analysointiin. Tämän tutkielman tavoitteena on selvittää, millaista informaatiota käännösprosessin kulusta ja sisällöstä sekä sen kääntäjäkohtaisuudesta saadaan ottamalla tutkimuskohteeksi aiempia tutkimuksia pidemmät tauot sekä sanakirjojen käyttö käännösprosessin aikana. Tämän tutkielman aineisto kerättiin hyödyntämällä tietokoneohjelmaa nimeltä Scriptlog, joka tallentaa …

Viruses are ancient parasites that have influenced the evolution of contemporary and archaic forms of life

Data from: Virus epidemics can lead to a population-wide spread of intragenomic parasites in a previously parasite-free asexual population

2014

In a recent issue of Molecular Ecology the role of intragenomic parasites in maintaining sexual reproduction was both experimentally evaluated by Kraaijeveld et al. and discussed by Crespi and Schwander. The prevalence of sex is difficult to explain, due to its costs when compared with asexual reproduction. Yet, as reviewed by Crespi and Schwander, sex can be favorable in the presence of proliferating transposons. Transposons are similar to mutations, in that their integration to non-neutral loci is likely to have deleterious effects, and sexual recombination provides a potential mechanism to confine their accumulation.

Norovirus infections and seroprevalence of genotype gii.4-specific antibodies in a spanish population

2015

Genotype II.4 noroviruses (NoVs) are a leading cause of epidemic acute gastroenteritis in children and adults worldwide. The prevalence of different NoV genotypes causing outbreaks and sporadic cases of acute gastroenteritis in the region of Valencia, Spain, during a 4-year period (2008–11) was investigated. NoVs were detected in 42 out of 55 (76.3%) outbreaks and in 26 out of 332 (7.8%) sporadic cases of acute gastroenteritis. Genogroup GII strains were predominant in outbreaks and sporadic cases. Different genotype GII.4 variants were found (Yerseke_2006a, Den Haag_2006b, Apeldoorn_2007, and New Orleans_2009), with the latter variant detected most frequently (35.3%). A recombinant P domai…

Macrolides May Prevent Severe Acute Respiratory Syndrome Coronavirus 2 Entry into Cells: A Quantitative Structure Activity Relationship Study and Exp…

2021

The global pandemic caused by the emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is threatening the health and economic systems worldwide. Despite the enormous efforts of scientists and clinicians around the world, there is still no drug or vaccine available worldwide for the treatment and prevention of the infection. A rapid strategy for the identification of new treatments is based on repurposing existing clinically approved drugs that show antiviral activity against SARS-CoV-2 infection. In this study, after developing a quantitative structure activity relationship analysis based on molecular topology, several macrolide antibiotics are identified as promising SARS-…

Generation of multifunctional murine monoclonal antibodies specifically directed to the VP1unique region protein of human parvovirus B19.

2007

Little is known about the VP1unique region (VP1u), a part of one major capsid protein of human parvovirus B19 (B19), concerning its involvement in viral replication and infection cycle. Showing a phospholipase A2 (PLA2)-like activity, which is discussed to be necessary for viral release from host cell, its precise function remains unclear. The purpose of this study was to generate multifunctional monoclonal antibodies (mabs) for different applications that may be useful in investigating VP1u's relevance. To establish antiVP1u antibodies, spleen cells from Balb/c mice immunized with purified recombinant viral protein were used for generating antibody-producing hybridoma cell lines. Usability…

Screening for inhibitors of HIV gp120-CD4 binding using an enzyme-linked immunoabsorbent assay.

1993

Binding of the HIV-1 major viral surface glycoprotein, gp120, to the major cell receptor, CD4, is essential for HIV infection of the target cell and syncytium formation. An enzyme-linked immunoassay using solid phase CD4 was used to quantitate the binding of HIV-1 gp120 to CD4, and to assess the activity and mechanism of action of putative inhibitors of that reaction. Monoclonal antibodies to the gp120 binding site on CD4 (e.g., Leu3a) blocked gp120 binding, while monoclonal antibodies to other portions of CD4 (e.g. OKT4) did not. Both aurintricarboxylic acid and sulfonated polysaccharides (e.g., dextran sulfate) blocked CD4-gp120 interactions by binding to the CD4 component. Human polyclon…

Short synthetic CDR-peptides forming the antibody combining site of the monoclonal antibody against RNA bacteriophage fr neutralize the phage activit…

1996

The construction of a mouse hybridoma FRS2 secreting neutralizing monoclonal antibody specific for RNA bacteriophages fr, MS2 and GA is reported. The genes encoding the variable domains of the monoclonal antibody FRS2 heavy and light chains were cloned and sequenced and the corresponding complementarity determining region (CDR) peptides were chemically synthesized. The CDR-peptides were tested for their ability to neutralize the activity of RNA phage fr and related RNA phages MS2 and GA. The CDR-derived peptides H2, L2 and L3 interacted with the fr phage particles and neutralized fr phage activity. Two of these peptides-H2 and L3 also had the ability to neutralize partly the activity of rel…

Conformational and linear epitopes on virus-like particles of human papillomavirus type 33 identified by monoclonal antibodies to the minor capsid pr…

1995

The organization of epitopes on the minor capsid protein L2 of human papillomavirus (HPV) type 33 has been analysed using three monoclonal antibodies (MAbs) generated against a large fragment of the L2 protein (amino acids 82-259) expressed as a glutathione S-transferase fusion protein. The topology of the L2 epitopes has been investigated with respect to the structure of HPV-33 virus-like particles (VLPs). Two of the MAbs reacted with linear epitopes which were mapped to amino acids 153-160 and 163-170, respectively. These epitopes were accessible in denatured but not in native VLPs consisting of L1 and L2, suggesting an internal location. The third antibody was unable to detect denatured …

Current Concepts in Therapy of Chronic Rhinosinusitis and Nasal Polyposis

2004

The exact pathophysiological mechanisms leading to chronic rhinosinusitis (CRS) still to a large extent remain obscure. However, recently there has been some progress in elucidating the etiology of nasal polyposis, especially regarding tissue eosinophilia as well as the role of aspirin intolerance and eicosanoid mediators. Endonasal sinus surgery has evolved to be the treatment of choice in CRS and nasal polyposis in all cases where conservative treatment has failed or resulted in only a partial or temporary relief. Today, state of the art in surgical technique includes the ability to combine microscopic and endoscopic procedures. Regardless of technical advances like powered instrumentatio…
