Semaphorin 3A (Sema3A) is a cell-secreted protein that participates in the axonal guidance pathways. Sema3A acts as a canonical repulsive axon guidance molecule, inhibiting CNS regenerative axonal growth and propagation. Therefore, interfering with Sema3A signaling is proposed as a therapeutic target for achieving functional recovery after CNS injuries. It has been shown that Sema3A adheres to the proteoglycan component of the extracellular matrix (ECM) and selectively binds to heparin and chondroitin sulfate-E (CS-E) glycosaminoglycans (GAGs). We hypothesize that the biologically relevant interaction between Sema3A and GAGs takes place at Sema3A C-terminal polybasic region (SCT). The aims of this study were to characterize the interaction of the whole Sema3A C-terminal polybasic region (Sema3A 725–771) with GAGs and to investigate the disruption of this interaction by small molecules. Recombinant Sema3A basic domain was produced and we used a combination of biophysical techniques (NMR, SPR, and heparin affinity chromatography) to gain insight into the interaction of the Sema3A C-terminal domain with GAGs. The results demonstrate that SCT is an intrinsically disordered region, which confirms that SCT binds to GAGs and helps to identify the specific residues involved in the interaction. NMR studies, supported by molecular dynamics simulations, show that a new peptoid molecule (CSIC02) may disrupt the interaction between SCT and heparin. Our structural study paves the way toward the design of new molecules targeting these protein–GAG interactions with potential therapeutic applications. ; This work was funded by the European Union Seventh Framework Programme (FP7/2007–2013) under Project VISION, grant No. 304884, the Spanish Ministry of Science and Innovation/Spanish Research Agency (MCI/AEI/FEDER, RTI2018–096182-B-I00) and AGAUR (2017 SGR 208). ; Peer reviewed

Resumo O artigo procura fazer um duplo balanço da Semana de Arte Moderna e da Independência. Mais do que isso, pretende explorar livremente a relação entre os dois acontecimentos, em uma perspectiva que já pode ser chamada de longa duração. Para realizar o balanço, são utilizados como materiais especialmente trabalhos sobre o pensamento político e social brasileiro. Procura-se, sobretudo, esboçar uma interpretação do modernismo brasileiro, na qual é ressaltado, em dissonância com o que pode ser chamado de uma espécie de sensibilidade sobre 1922 que tem ganhado força, seu caráter fundamentalmente democrático. De maneira complementar, para que o argumento ganhe corpo, mobiliza-se uma interpretação da Independência, identificada com Caio Prado Júnior e Florestan Fernandes, que chama a atenção para as deficiências democráticas de 1822, que marcam o país desde então. Relaciona-se, a partir daí, em sentido oposto, a orientação democrática de 1922.

Although a pathway (Cα-oxidation) for shortening the hydrocarbon chain of saturated fatty acids has already been reported for the UPO from Marasmius rotula (MroUPO), it turned out that rCciUPO and AaeUPO shorten the chain length of both saturated and unsaturated fatty acids in a different way. Thus, the reaction sequence does not necessarily start at the Cα-carbon (adjacent to the carboxyl group), as in the case of MroUPO, but proceeds through the subterminal (ω-1 and ω-2) carbons of the chain via several oxygenations. This new type of shortening leads to the formation of a dicarboxylic fatty acid reduced in size by two carbon atoms in the first step, which can subsequently be further shortened, carbon by carbon, by the UPO Cα-oxidation mechanism.

At the end of the 1870s, the oppressive policies of the Argentine State were intensified towards the indigenous people linked to the Southern Border, visible in the punitive expeditions of 1878-1879. In the case of theranqueles, located in the centralPampa, these actions were part of previous strategies of attrition, carried out by the military commanders ofSan LuisandCórdobathrough the diplomatic channel, softening campaigns and co-optation of contingents who, both forced and voluntarily, migrated to the fortsVilla MercedesandSarmiento. From a line of investigation that seeks to reconstruct the itineraries of theranquelessubmitted in the aforementioned context, the article characterizes the imprisonment of the indigenous people taken by the 3rd Expeditionary Division (April-August 1879) under the leadership of Colonel Eduardo Racedo. Its purpose is to describe their living conditions while they were in thePitral Lauquencamp (nearPoitagué), understanding that it simultaneously acted as a place of concentration and distribution of prisoners. ; Al terminar la década de 1870 se intensificaron las políticas opresivas del Estado argentino para con los indígenas ligados a la Frontera Sur, visibles en las expediciones punitivas de 1878-1879. En el caso de los ranqueles, situados en la pampa central, estas acciones se enmarcan en estrategias previas de desgaste ejecutadas por los mandos militares de San Luis y Córdoba a través de la vía diplomática, las campañas de ablandamiento y cooptación de contingentes que migrabande manera forzaday por presentación a los fuertes Villa Mercedes y Sarmiento. Desde una línea de investigación que busca reconstruir los itinerarios de los ranqueles sometidos en ese contexto, el artículo caracteriza elaprisionamiento de los indígenas tomados por la 3aDivisión Expedicionaria (abril-agosto de 1879) bajo el liderazgo del coronel Eduardo Racedo. Su finalidad es describir sus condiciones de vida mientras estuvieron depositados en el campamento Pitral Lauquen (cercano a Poitagué), lugar de concentración y distribución de prisioneros.
