Self-organised pattern formation increases local diversity in metacommunities.

Ecol Lett 2021 Sep 23. Epub 2021 Sep 23.

Institute of Biochemistry and Biology, University of Potsdam, Potsdam, Germany.

Self-organised formation of spatial patterns is known from a variety of different ecosystems, yet little is known about how these patterns affect the diversity of communities. Here, we use a food chain model in which autotroph diversity is described by a continuous distribution of a trait that affects both growth and defence against heterotrophs. On isolated patches, diversity is always lost over time due to stabilising selection, and the local communities settle on one of two alternative stable community states that are characterised by a dominance of either defended or undefended species.

The Effects of Intensive Neurorehabilitation on Sequence Effect in Parkinson's Disease Patients With and Without Freezing of Gait.

Front Neurol 2021 7;12:723468. Epub 2021 Sep 7.

Movement Analysis Research Unit, IRCCS Mondino Foundation, Pavia, Italy.

The sequence effect (SE), defined as a reduction in amplitude of repetitive movements, is a common clinical feature of Parkinson's disease (PD) and is supposed to be a major contributor to freezing of gait (FOG). During walking, SE manifests as a step-by-step reduction in step length when approaching a turning point or gait destination, resulting in the so-called destination sequence effect (dSE). Previous studies explored the therapeutic effects of several strategies on SE, but none of them evaluated the role of an intensive rehabilitative program. Read More

J Inorg Biochem 2021 Aug 27;225:111593. Epub 2021 Aug 27.

Department of Chemistry and Biochemistry, University of North Carolina at Greensboro, Greensboro, NC 27402, USA. Electronic address:

In this study on model compounds for the resting oxidized state of the iron‑copper binuclear center in cytochrome c oxidase (CcO), we describe the synthesis of a new μ-oxo-heme/Cu complex, [(TPP)Fe-O-Cu(tmpa)][B(CF)] (2) {TPP: tetraphenyl porphyrinate(2-); TMPA: tris(2-pyridylmethylamine)}, as well as two protonation events for three μ-oxo-heme/Cu complexes with varying peripheral substituents on the heme site. The addition of increasing amounts of strong acid to these μ-oxo-heme/Cu systems successively led to the generation of the corresponding μ-hydroxo, μ-aquo, and the dissociated complexes. The heme/Cu assemblies bridged through a water ligand are reported here for the first time and the H NMR and F NMR spectral properties are consistent with antiferromagnetically coupled high-spin iron(III) and copper(II) centers.
