HOMO Energy-Level Lifting in p-Type O-Doped Graphenoids: Synthesis of Electrochromic Alkoxy-Decorated Xanthenoxanthenes

Abstract A series of novel O-doped polycyclic aromatic hydrocarbons, bearing a different number of electron-donating alkoxy substituents, has been prepared using a novel copper-promoted anaerobic protocol for the cyclisation of highly electron rich peri-xanthenoxanthene molecular modules. The effect of the number and position of the alkoxy substituents on the optoelectronic properties has thus been investigated, unveiling p-type semiconducting properties. All molecules displayed a significant colour change upon oxidation, suggesting that these compounds can be used to devise chromogenic materials to engineer electrochromic devices

SUN-PO316: Impact of Protein Intake and High-Fat Diet on Muscle Protein Synthesis and Lipid Infiltration in Relation to Aging in Rats

Part of special issue: Abstracts of the 41st ESPEN Congress, Krakow, Poland, 31 August–3 September, 2019International audienceRationale: Ectopic lipid deposition impairs muscle anabolic responseespecially during aging. We hypothesized that the anabolic efficiencyof dietary protein in skeletal muscle might be affected by high-fat diet.The objective of the study was to investigate muscle protein synthesisin response totwolevels of protein intake combined totwo levels of fatintake. Methods: Two groups of sixty adult and forty-nine old male Wistarrats were randomly divided into four groups: isocaloric standard diet (12% protein, 14% lipid, as STD12); isocaloric standard (high-protein)diet (25% protein, 14% lipid, STD25); hypercaloric high-fat (normal-protein) diet (12% protein, 45% lipid, HFD12); and hypercaloric high-fat (high-protein) diet (25% protein, 45% lipid, HFD25). The nutritionalintervention lasted 10 weeks. The fractional synthesis (FSR) andabsolute synthesis rates (ASR) of mixed muscle proteins werecalculated using isotopically labelled13C-Valine incorporation intibialis anterior (TA). Muscle lipid content was assessed usingchromatography method. Results: Rats in the high-fat diet groups self-limited their food intake,so that energy intake was not different among the groups. Regardlessof dietary intervention, TAweight was lower in old groups compared totheir adult counterparts (all p values Conclusions: Aging is characterized by reduced muscleweight despiteincreased FSR, suggesting specific alterations in the nutritionalregulation of muscle protein turnover. In isocaloric conditions, higherprotein intake modulates muscle lipid infiltration, without improvingage-related anabolic resistance in old rats fed a high-fat diet

El ambiente entre representación y ecología - Un estudio de caso en Guatemala, siglo XIX The environment: between representation and ecology - A case study of Guatemala, 19th century

<abstract language="por">A Guatemala - onde a cultura do café assumiu papel relevante - foi alvo de intensa idealização de sua natureza, ao mesmo tempo em que foi exaltada como uma nação essencialmente agrícola. Tais imagens se construíram tanto sobre bases naturais como sobre representa ções sociais e históricas. Muitos estudos apontam a existência de duas macro-regiões homogêneas no seu território. Entretanto, cada uma delas apresenta uma composição ecológica muito mais variada do que se supõe tradicionalmente, o que se configura como um dos principais fatores de compreensão da constituição histórica das regiões de plantio do café naquele país.<br>Guatemala - where the culture of coffee became relevant - was the target of intense idealization of its nature, at the same time that it was exalted as an essentially agricultural nation. Such images were built upon natural bases as well as upon social and historical representations. Many studies point to the existence of two homogeneous macroregions in the territory. However, each one of them presents an ecological composition much more varied than is traditionally supposed, which is one of the main factors for understanding the historical constitution of coffee plantation regions in that country
