TL;DR: This study suggests that attentional and executive impairment, as well as depression and anxiety, may play a critical role in the development of poststroke fatigue (PSF) following minor infarcts.
Abstract: Objective: To explore the potential relationship between fatigue following strokes and poststroke mood, cognitive dysfunction, disability, and infarct site and to determine the predictive factors in the development of poststroke fatigue (PSF) following minor infarcts. Methods: Ninety-nine functionally active patients aged less than 70 years with a first, nondisabling stroke (NIH Stroke Scale score ≤6 in acute phase and ≤3 after 6 months, modified Rankin Scale score ≤1 at 6 months) were assessed during the acute phase and then at 6 (T1) and 12 months (T2) after their stroke. Scores in the Fatigue Assessment Inventory were described and correlated to age, gender, neurologic and functional impairment, lesion site, mood scores, neuropsychological data, laboratory data, and quality of life at T1 and T2 using a multivariate logistic regression analysis in order to determine which variables recorded at T1 best predicted fatigue at T2. Result: As many as 30.5% of the patients at T1 and 34.7% at T2 (11.6% new cases between T1 and T2) reported fatigue. At both 6 and 12 months, there was a significant association between fatigue and a reduction in professional activity. Attentional-executive impairment, depression, and anxiety levels remained associated with PSF throughout this time period, underlining the critical role of these variables in the genesis of PSF. There was no significant association between the lesion site and PSF. Conclusion: This study suggests that attentional and executive impairment, as well as depression and anxiety, may play a critical role in the development of PSF.

TL;DR: A glass-forming supramolecular material that is based on a trifunctional low-molecular-weight monomer ((UPyU)3TMP), whose properties are governed by its cross-linked architecture and the large content of the binding motif, exhibits a high stiffness and offers excellent coating and adhesive properties.
Abstract: The reversible and dynamic nature of non-covalent interactions between the constituting building blocks renders many supramolecular polymers stimuli-responsive. This was previously exploited to create thermally and optically healable polymers, but it proved challenging to achieve high stiffness and good healability. Here we present a glass-forming supramolecular material that is based on a trifunctional low-molecular-weight monomer ((UPyU)3TMP). Carrying three ureido-4-pyrimidinone (UPy) groups, (UPyU)3TMP forms a dynamic supramolecular polymer network, whose properties are governed by its cross-linked architecture and the large content of the binding motif. This design promotes the formation of a disordered glass, which, in spite of the low molecular weight of the building block, displays typical polymeric behaviour. The material exhibits a high stiffness and offers excellent coating and adhesive properties. On account of reversible dissociation and the formation of a low-viscosity liquid upon irradiation with ultraviolet light, rapid optical healing as well as (de)bonding on demand is possible.

TL;DR: In this article, a detailed geomorphic map (1:1000) of all forms related to debris flows as well as on tree-ring series from 401 heavily affected trees (Larix decidua mill and Picea abies (L.) Karst) growing in or next to deposits are reconstructed.

TL;DR: Interestingly, induction of PR‐Q and PAR‐1 by soluble sugars was essentially restricted to fully expanded leaves and was independent of plant age, hinting to the possibility of salicylic acid‐independent defense reactions of plants against pathogens by induction of a set of PR proteins in source leaves.

TL;DR: This review focuses on the defense reactions associated with SAR, such as the production of so-called pathogenesis-related proteins or the buildup of histological barriers, as well as various natural and synthetic signal compounds.
Abstract: The defense of plants against infectious microorganisms involves constitutive barriers as well as reactions induced upon contact with potential pathogens. Systemic acquired resistance (SAR) is characterized by an activation of a broad spectrum of host defense mechanisms, locally at the site of the initial pathogen attack as well as systemically, in tissues untouched by the pathogen. SAR can provide resistance against widely diverse organisms such as fungi, bacteria, and viruses. Induced defense reactions associated with SAR involve both biochemical and cytological changes, and depend on the production of a signal that is translocated to other parts of the plant, where it triggers resistance. This review focuses on the defense reactions associated with SAR, such as the production of so-called pathogenesis-related proteins or the buildup of histological barriers, as well as various natural and synthetic signal compounds.
