Chloroterpenes and other organochlorines in Baltic, Finnish and Arctic wildlife

1991

Abstract Chloroterpene mixtures were analyzed as toxaphene (TOX) in Baltic, Finnish and Arctic fish, seal and bird samples together with DDT residues, hexachlorocyclohexanes (HCH), hexachlorobenzene (HCBz), chlordanes, hexachloronaphthalenes (HxCN), PCBs, PCDDs and PCDFs. TOX was found to be the most globally (evenly) distributed organochlorine compound in Scandinavia, thus far. TOX seemed to bioaccumulate significantly in fish but not in predatory birds in Finland.

Willingness of Student to Favour the Protection of Endangered Species in a Trade-off Conflict in Finland

1994

Abstract This paper explores the willingness of Finnish students to favour protection of endangered species in a hypothetical trade-off conflict, where conservation would cause an increase in the household energy cost. The most striking result was the very distinct preference of species which the students felt worth protecting. The students favoured species which are well known, taxonomically close to man and actually endangered. Major differences occurred among students due to sex, educational institute, nature-related activity groups, as well as knowledge of nature and conservation issues.

Analysis of the TK enzyme complex induced by HSV types 1 and 2 by means of isoelectric focusing and polyacrylamide gel electrophoresis.

1982

Recently we have described that the Herpes simplex virus (HSV)-induced thymidine kinase (TK) induces AMP- and ADP-dThd-5'-phosphotransferase activities. We now demonstrate the heterogeneity of the described activities in isoelectric focusing experiments and polyacrylamide gel electrophoresis. A TK--mutant of HSV type 1 fails to induce these activities. The activities of the type 1 enzyme complex was neutralized by an anti-HSV-serum. The TK-enzyme complex expressed in LTK--cells transformed to a TK+-phenotype by sheared HSV-1 DNA was compared with the wild type TK complex in isoelectric focusing experiments. Additionally we demonstrate that the HSV type 1 enzyme complex has thymidylate kinas…

Mutant Plasticity Related Gene 1 (PRG1) acts as a potential modifier in SCN1A related epilepsy

2018

ABSTRACTPlasticity related gene 1 encodes a cerebral neuron-specific synaptic transmembrane protein that modulates hippocampal excitatory transmission on glutamatergic neurons. In mice, homozygous Prg1-deficiency results in juvenile epilepsy. Screening a cohort of 18 patients with infantile spasms (West syndrome), we identified one patient with a heterozygous mutation in the highly conserved third extracellular phosphatase domain (p.T299S). The functional relevance of this mutation was verified by in-utero electroporation of a mutant Prg1 construct into neurons of Prg1-knockout embryos, and the subsequent inability of hippocampal neurons to rescue the knockout phenotype on the single cell l…

Combined Bacteriophage and Antibiotic Treatment Prevents Pseudomonas aeruginosa Infection of Wild Type and cftr- Epithelial Cells

2020

International audience; With the increase of infections due to multidrug resistant bacterial pathogens and the shortage of antimicrobial molecules with novel targets, interest in bacteriophages as a therapeutic option has regained much attraction. Before the launch of future clinical trials, in vitro studies are required to better evaluate the efficacies and potential pitfalls of such therapies. Here we studied in an ex vivo human airway epithelial cell line model the efficacy of phage and ciprofloxacin alone and in combination to treat infection by Pseudomonas aeruginosa. The Calu-3 cell line and the isogenic CFTR knock down cell line (cftr-) infected apically with P. aeruginosa strain PAO…

Tradizioni etnofarmacobotaniche in alcune comunità rurali dei Monti di Trapani (Sicilia occidentale)

2014

Ethnopharmacobotanical traditions in some rural communities of Trapani Mountains (West-Sicily). – The results refer an ethnopharmacobotanical study carried out in the territories of Valderice, Busto Palizzolo, Custonaci and San Vito Lo Capo, in the Trapani Mountains. There are 155 plants used in etno-medicine. The etnofarmacobotanical use of spontaneous and cultivated taxa represents an ecosystem services provided by biodiversity in the traditional agricultural systems of this area.

Eupelmus spermophilus Silvestri (Hymenoptera: Chalcidoidea), an Indigenous Olive Seed Wasp Potentially Harmful to Olive Growing in the Western Cape, …

2021

The objectives of this study were the specific taxonomic confirmation of the main olive seed wasp (OSW) attacking commercial olives in the Western Cape, to investigate monitoring methods and seasonal occurrence of OSW, to determine the potential economic damage of infestations, and to ascertain the geographic distribution of OSW in the regions where olives are cultivated in the Western Cape. Morphological and molecular methods were used to identify all the species obtained from cultivated olives at two trial sites near Stellenbosch and Agter-Paarl. Eupelmus spermophilus Silvestri (Hymenoptera: Chalcidoidea) was by far the most frequent and widespread olive seed wasp. Monitoring with yellow …

On the interpretability and computational reliability of frequency-domain Granger causality

2017

This Correspondence article is a comment which directly relates to the paper “A study of problems encountered in Granger causality analysis from a neuroscience perspective” (Stokes and Purdon, 2017). We agree that interpretation issues of Granger causality (GC) in neuroscience exist, partially due to the historically unfortunate use of the name “causality”, as described in previous literature. On the other hand, we think that Stokes and Purdon use a formulation of GC which is outdated (albeit still used) and do not fully account for the potential of the different frequency-domain versions of GC; in doing so, their paper dismisses GC measures based on a suboptimal use of them. Furthermore, s…

Climate change effects on trematodiases, with emphasis on zoonotic fascioliasis and schistosomiasis.

2009

The capacity of climatic conditions to modulate the extent and intensity of parasitism is well known since long ago. Concerning helminths, among the numerous environmental modifications giving rise to changes in infections, climate variables appear as those showing a greater influence, so that climate change may be expected to have an important impact on the diseases they cause. However, the confirmation of the impact of climate change on helminthiases has been reached very recently. Only shortly before, helminthiases were still noted as infectious diseases scarcely affected by climate change, when compared to diseases caused by microorganisms in general (viruses, bacteriae, protozoans). Th…
