Erträge von Winterweizen in einem Agroforstsystem zur Energieholzgewinnung im ökologischen Landbau
The study is part of the research project "Development and testing of an agroforestry system combining organic agriculture and short rotation coppice". Cooperation partners are the Bavarian State Institute for Agriculture (LfL) and the Bavarian State Institute of Forestry (LWF). The two experimental sites are located in the northern
Munich gravel plain near Freising and in the southern part of the Franconian Jurassic near Kaisheim. Aim of the study was to compare the yield of agricultural crops in an
alley cropping system for woody biomass production with a standard cultivation without trees on the field. A positive effect of periodically harvested tree stripes on the
yield of the agricultural crops is expected. First results show that there were no significant differences in the overall marketable yield of winter wheat in the
agroforestry system compared to the reference site without trees. The spatial distribution of the yield, however, differed significantly. In close proximity to the tree
stripes a significant reduction of the marketable yield could be measured. These lower yields were equalized by higher yields in bigger distances of the tree stripes
Schnellwachsende Gehölze zur Energiegewinnung im ökologischen Landbau - Etablierung und Wuchsleistung verschiedener Baumarten
So far there is only little experience with the cultivation of coppicing fast-growing tree species in German organic agriculture. The research project investigated the establishment and the performance of different tree species - black alder (Alnus glutinosa), grey alder (Alnus incana) and two hybrid poplar clones ('Max 1', 'Max 3') under organic conditions. Various strategies to reduce weed competition were examined. Different undersown crops (Medicago lupulina, Trifolium repens, Camelina sativa, Secale cereale) and a self-degradable mulch membrane were compared with an untreated control. The two experimental sites are located in Southern Bavaria (Germany). All tree species could be successfully established on both experimental sites. The results show that during the first three years the trees on self-degradable mulch membrane growd best, and reached the lowest heigth on black medic.
A recommendation regarding choice of tree species and strategies of establishment can be given after tree harvest and after an economic evaluation
Libraries as Journal Publishers
Increasing library involvement in journal hosting and publishing is an important topic for serialists. This installment of "The Balance Point" column presents articles that offer descriptions and analyses of the current state of ideas and activities related to libraries as publishers. Featured authors discuss the publishing and journal hosting tasks libraries can perform, programs and activities related to journal hosting, titles hosted, challenges, next steps and the benefits or drawbacks foreseen in the current paths of the libraries they represent
Entwicklung und Erprobung eines Agroforstsystems im ökologischen Landbau zur Energieholzgewinnung
Das Projekt „Entwicklung und Erprobung eines Agroforstsystems im ökologischen Landbau zur Energieholzgewinnung“ ist eine Kooperation der beiden bayerischen Landesanstalten für Landwirtschaft (LfL) und für Wald und Forstwirtschaft (LWF). Die Versuchsstandorte liegen in der nördlichen Münchener Ebene bei Freising und im südlichen Frankenjura in der Nähe von Kaisheim. Die zentrale Frage des Projektes ist, welche Erträge und Qualitäten die landwirtschaftlichen Feldfrüchte in einem Agroforstsystem im Vergleich zur herkömmlichen Bewirtschaftung ohne Bäume auf dem Acker liefern. Es wird eine positive Wirkung von Baumstreifen im Kurzumtrieb auf den Ertrag der dazwischen liegenden landwirtschaftlichen Kulturen erwartet. Außerdem wird untersucht, ob in einem Agroforstsystem die gesamte Biomasseerzeugung im Vergleich zur reinen landwirtschaftlichen Nutzung nachhaltig höher ist. Die möglichst effiziente Etablierung von schnellwachsenden Baumarten auf Flächen des Ökolandbaus ist eine weitere Fragestellung des Projekts. Erste Beobachtungen unterschiedlicher Begründungsverfahren und zum Leistungsvergleich verschiedener Hybrid-Pappelklone mit heimischen Baumarten werden vorgestellt
Benzylglucosinolate Derived Isothiocyanate from Tropaeolum majus Reduces Gluconeogenic Gene and Protein Expression in Human Cells
Nasturtium (Tropaeolum majus L.) contains high concentrations of
benzylglcosinolate. We found that a hydrolysis product of benzyl
glucosinolate—the benzyl isothiocyanate (BITC)—modulates the intracellular
localization of the transcription factor Forkhead box O 1 (FOXO1). FoxO
transcription factors can antagonize insulin effects and trigger a variety of
cellular processes involved in tumor suppression, longevity, development and
metabolism. The current study evaluated the ability of BITC—extracted as
intact glucosinolate from nasturtium and hydrolyzed with myrosinase—to
modulate i) the insulin-signaling pathway, ii) the intracellular localization
of FOXO1 and, iii) the expression of proteins involved in gluconeogenesis,
antioxidant response and detoxification. Stably transfected human osteosarcoma
cells (U-2 OS) with constitutive expression of FOXO1 protein labeled with GFP
(green fluorescent protein) were used to evaluate the effect of BITC on FOXO1.
Human hepatoma HepG2 cell cultures were selected to evaluate the effect on
gluconeogenic, antioxidant and detoxification genes and protein expression.
BITC reduced the phosphorylation of protein kinase B (AKT/PKB) and FOXO1;
promoted FOXO1 translocation from cytoplasm into the nucleus antagonizing the
insulin effect; was able to down-regulate the gene and protein expression of
gluconeogenic enzymes; and induced the gene expression of antioxidant and
detoxification enzymes. Knockdown analyses with specific siRNAs showed that
the expression of gluconeogenic genes was dependent on nuclear factor
(erythroid derived)-like2 (NRF2) and independent of FOXO1, AKT and NAD-
dependent deacetylase sirtuin-1 (SIRT1). The current study provides evidence
that BITC might have a role in type 2 diabetes T2D by reducing hepatic glucose
production and increasing antioxidant resistance

Functional network resilience to pathology in presymptomatic genetic frontotemporal dementia
© 2019 The Authors. Published by Elsevier Inc. This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/)The presymptomatic phase of neurodegenerative diseases are characterized by structural brain changes without significant clinical features. We set out to investigate the contribution of functional network resilience to preserved cognition in presymptomatic genetic frontotemporal dementia. We studied 172 people from families carrying genetic abnormalities in C9orf72, MAPT, or PGRN. Networks were extracted from functional MRI data and assessed using graph theoretical analysis. We found that despite loss of both brain volume and functional connections, there is maintenance of an efficient topological organization of the brain's functional network in the years leading up to the estimated age of frontotemporal dementia symptom onset. After this point, functional network efficiency declines markedly. Reduction in connectedness was most marked in highly connected hub regions. Measures of topological efficiency of the brain's functional network and organization predicted cognitive dysfunction in domains related to symptomatic frontotemporal dementia and connectivity correlated with brain volume loss in frontotemporal dementia. We propose that maintaining the efficient organization of the brain's functional network supports cognitive health even as atrophy and connectivity decline presymptomatically.This work was funded by the UK Medical Research Council, the Italian Ministry of Health, and the Canadian Institutes of Health Research as part of a Centres of Excellence in Neurodegeneration grant [grant number CoEN015].
