Subsequent salvage logging, a widespread management practice conducted predominantly to recover economic capital, produces further disturbance and impacts biodiversity worldwide. Hence, naturally disturbed forests are among the most threatened habitats in the world, with consequences for their associated biodiversity. However, there are no evidence-based benchmarks for the proportion of area of naturally disturbed forests to be excluded from salvage logging to conserve biodiversity. We apply a mixed rarefaction/extrapolation approach to a global multi-taxa dataset from disturbed forests, including birds, plants, insects and fungi, to close this gap. We find that 757\% (mean +/- SD) of a naturally disturbed area of a forest needs to be left unlogged to maintain 90\% richness of its unique species, whereas retaining 50\% of a naturally disturbed forest unlogged maintains 73 +/- 12\% of its unique species richness. These values do not change with the time elapsed since disturbance but vary considerably among taxonomic groups. Salvage logging has become a common practice to gain economic returns from naturally disturbed forests, but it could have considerable negative effects on biodiversity. Here the authors use a recently developed statistical method to estimate that ca. 75\% of the naturally disturbed forest should be left unlogged to maintain 90\% of the species unique to the area.}, language = {en} } @article{PostemaHoogmanAmbrosinoetal.2021, author = {Postema, Merel C. and Hoogman, Martine and Ambrosino, Sara and Asherson, Philip and Banaschewski, Tobias and Bandeira, Cibele E. and Baranov, Alexandr and Bau, Claiton H.D. and Baumeister, Sarah and Baur-Streubel, Ramona and Bellgrove, Mark A. and Biederman, Joseph and Bralten, Janita and Brandeis, Daniel and Brem, Silvia and Buitelaar, Jan K. and Busatto, Geraldo F. and Castellanos, Francisco X. and Cercignani, Mara and Chaim-Avancini, Tiffany M. and Chantiluke, Kaylita C. and Christakou, Anastasia and Coghill, David and Conzelmann, Annette and Cubillo, Ana I. and Cupertino, Renata B. and de Zeeuw, Patrick and Doyle, Alysa E. and Durston, Sarah and Earl, Eric A. and Epstein, Jeffery N. and Ethofer, Thomas and Fair, Damien A. and Fallgatter, Andreas J. and Faraone, Stephen V. and Frodl, Thomas and Gabel, Matt C. and Gogberashvili, Tinatin and Grevet, Eugenio H. and Haavik, Jan and Harrison, Neil A. and Hartman, Catharina A. and Heslenfeld, Dirk J. and Hoekstra, Pieter J. and Hohmann, Sarah and H{\o}vik, Marie F. and Jernigan, Terry L. and Kardatzki, Bernd and Karkashadze, Georgii and Kelly, Clare and Kohls, Gregor and Konrad, Kerstin and Kuntsi, Jonna and Lazaro, Luisa and Lera-Miguel, Sara and Lesch, Klaus-Peter and Louza, Mario R. and Lundervold, Astri J. and Malpas, Charles B and Mattos, Paulo and McCarthy, Hazel and Namazova-Baranova, Leyla and Nicolau, Rosa and Nigg, Joel T. and Novotny, Stephanie E. and Oberwelland Weiss, Eileen and O'Gorman Tuura, Ruth L. and Oosterlaan, Jaap and Oranje, Bob and Paloyelis, Yannis and Pauli, Paul and Picon, Felipe A. and Plessen, Kerstin J. and Ramos-Quiroga, J.

Here, we performed the largest ever analysis of brain left-right asymmetry in ADHD, using 39 datasets of the ENIGMA consortium. Methods We analyzed asymmetry of subcortical and cerebral cortical structures in up to 1,933 people with ADHD and 1,829 unaffected controls. Asymmetry Indexes (AIs) were calculated per participant for each bilaterally paired measure, and linear mixed effects modeling was applied separately in children, adolescents, adults, and the total sample, to test exhaustively for potential associations of ADHD with structural brain asymmetries. Results There was no evidence for altered caudate nucleus asymmetry in ADHD, in contrast to prior literature. In children, there was less rightward asymmetry of the total hemispheric surface area compared to controls (t = 2.1, p = .04). Lower rightward asymmetry of medial orbitofrontal cortex surface area in ADHD (t = 2.7, p = .01) was similar to a recent finding for autism spectrum disorder. There were also some differences in cortical thickness asymmetry across age groups. In adults with ADHD, globus pallidus asymmetry was altered compared to those without ADHD. However, all effects were small (Cohen's d from -0.18 to 0.18) and would not survive study-wide correction for multiple testing. Conclusion Prior studies of altered structural brain asymmetry in ADHD were likely underpowered to detect the small effects reported here. Altered structural asymmetry is unlikely to provide a useful biomarker for ADHD, but may provide neurobiological insights into the trait.}, language = {en} } @article{WeissSebaldSchwabetal.1973, author = {Weiss, H. and Sebald, Walter and Schwab, A.

Selective incorporation of radioactive amino acids by eilher mitochondrial protein synthesis when the cytoplasmic one is blocked or by the cytoplasmic protein synthesis, when the mitochondrial one is blocked, indicates that one cytochrome b polypeptide (mw 32 000) and one to three cytochrome aa3 polypeptides (mw 36 000, 28 000 and 18 000) are mitochondrial translation products, the other cytochrome b and cytochrome aa3 polypeptides cytoplasmic translation products. The delayed appearance of labeling in the cytochrome b and cytochrome aa3 polypeptides compared to the average cell protein after a pulse of <~H leueine revealed that these polypeptides are derived from separate pools of precursor polypeptides. The pool sizes range from 2 p. cent to 25 p. cent of the amount of the corresponding polypeptide present in the cytochromes. The 32 000 molecular weight polypeptide of cytochrome band at least the 18 000 molecular weight polypeptide of cytochrome aa\(_3\) are mitochondrial translation products as well in the fungus Neurospora crassa as in the insect Locusta migratoria.

However, the origin of these cells causes major problems: availability and standardization of the graft. Therefore, the generation of unlimited numbers of DA neurons from various types of stem or progenitor cells has been brought into focus. A source for DA neurons might be conditionally immortalized progenitor cells. The temperature-sensitive immortalized cell line CSM14.1 derived from the mesencephalon of an embryonic rat has been used successfully for transplantation experiments. This cell line was analyzed by unbiased stereology of cell type specific marker proteins and 2D-gel electrophoresis followed by mass spectrometry to characterize the differentially expressed proteome. Undifferentiated CSM14.1 cells only expressed the stem cell marker nestin, whereas differentiated cells expressed GFAP or NeuN and tyrosine hydroxylase. An increase of the latter cells during differentiation could be shown. By using proteomics an explanation on the protein level was found for the observed changes in cell morphology during differentiation, when CSM14.1 cells possessed the morphology of multipolar neurons. The results obtained in this study confirm the suitability of CSM14.1 cells as an in vitro model for the study of neuronal and dopaminergic differentiation in rats.}, language = {en} } @article{RodriguesWeissHewigetal.2021, author = {Rodrigues, Johannes and Weiß, Martin and Hewig, Johannes and Allen, John J.

As a result, many methods are being reconsidered, and researchers' degrees of freedom in these methods are being discussed as a potential source of inconsistencies across studies. New Method: With the aim of addressing these subjectivity issues, we have been working on a tutorial-like EEG (pre-)processing pipeline to achieve an automated method based on the semi-automated analysis proposed by Delorme and Makeig. Results: Two scripts are presented and explained step-by-step to perform basic, informed ERP and frequency-domain analyses, including data export to statistical programs and visual representations of the data. The open-source software EEGlab in MATLAB is used as the data handling platform, but scripts based on code provided by Mike Cohen (2014) are also included. Comparison with existing methods: This accompanying tutorial-like article explains and shows how the processing of our automated pipeline affects the data and addresses, especially beginners in EEG-analysis, as other (pre)-processing chains are mostly targeting rather informed users in specialized areas or only parts of a complete procedure. In this context, we compared our pipeline with a selection of existing approaches. Conclusion: The need for standardization and replication is evident, yet it is equally important to control the plausibility of the suggested solution by data exploration. Here, we provide the community with a tool to enhance the understanding and capability of EEG-analysis. We aim to contribute to comprehensive and reliable analyses for neuro-scientific research.}, language = {en} }
