INTRODUCTION This study seeks to describe the predictive value of the signal intensity ratio (SIR) in magnetic resonance imaging-turbo inversion recovery magnitude (MRI-TIRM) in patients with Graves' orbitopathy (GO) with regard to predictability of therapy response. METHODS Included in this prospective pilot study were 36 consecutive patients with GO and(More)
BACKGROUND AND AIMS Plasticity in structural and functional traits related to water balance may determine plant performance and survival in ecosystems characterized by water limitation or high levels of rainfall variability, particularly in perennial herbaceous species with long generation cycles. This paper addresses whether and the extent to which several(More)
Analyses of tree-ring anatomical features showed to be more sensitive to specific intra-seasonal environmental factors than tree-ring width in Tectona grandis and Pinus caribaea growing in a subtropical region. Earlywood vessels (EWV) and intra-annual density fluctuations (IADFs) in tree rings are influenced by intra-seasonal environmental factors, as have(More)
Quantitative wood anatomy analyzes the variability of xylem anatomical features in trees, shrubs, and herbaceous species to address research questions related to plant functioning, growth, and environment. Among the more frequently considered anatomical features are lumen dimensions and wall thickness of conducting cells, fibers, and several ray properties.(More)
This study provides new data and an alternative framework to the debate of tree carbon economy in a context of increasing stress. For long-living trees, the resilience in times of stress is directly linked to the amount of accessible reserves. Despite the simplicity of this principle, the understanding of how carbon reserves limit growth and/or induce(More)
Phloem osmolality and its components are involved in basic cell metabolism, cell growth, and in various physiological processes including the ability of living cells to withstand drought and frost. Osmolality and sugar composition responses to environmental stresses have been extensively studied for leaves, but less for the secondary phloem of plant stems(More)
Growth of herbaceous plants responds sensitively and rapidly to climate variability. Yet, little is known regarding how climate warming influences the growth of herbaceous plants, particularly in semi-arid sites. This contrasts with widely reported tree growth decline and even mortality in response to severe water deficits due to climate warming around the(More)
The most promising and representative earlywood vessel parameters were identified for dendroecological applications in oak. Recent improvements of methods used in tree-ring and quantitative wood anatomical studies have helped to widen the selection of parameters which contain environmental information. In the present study, we identified the most promising(More)
Dendroecological research uses information stored in tree rings to understand how single trees and even entire forest ecosystems responded to environmental changes and to finally reconstruct such changes. This is done by analyzing growth variations back in time and correlating various plant-specific parameters to (for example) temperature records.(More)
