The author, writer and filmmaker Neil Hollander has been having a successful career for more than three decades. He's been author of several books for kids and more books that serve as a manuals for surviving on open sea. With his latest books Hollander has been advocating for world peace and bringing closer to the public the horrific life of people living under military regime in Burma. He is also active as a public speaker covering these and similar subjects. As a filmmaker Hollander started his career back in 70's when together with Harald Mertes went on a voyage around the Ocean on a sailing boat, Spending three years on this trip he visited many places and learned many things about life on sea. Later he documented these finding in his book, which he also used as a screenplay for his awarded documentary film The Last Sailors: The Final Days of Working Sail. The film is hosted by Orson Welles who in this classic documentary film tells the story of the men who, with their ancient craft, still harness the wind and the sea for their livelihood. The film includes stories from people living all over the world, including countries like Egypt, Bangladesh, Indonesia, Brazil, Costa Rica and other places. Hollander is artist that is best known for his exhibitions hosted in collaboration with some world-recognized museums and art schools. In his career he has worked with the Smithsonian, the Deutsches Museum and the Jim Thompson House in Bangkok. Lately his project are publicly visible at his portfolio at Rhode Island School of Design (RISD). Projects worth mentioning as one of the best in his portfolio include Hollander's Nobel Voices, Neil Hollander Burma A Human Tragedy, Birds of Passage, H for Hunger, to name a few.

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

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.

International audience ; Although nuclear energy forms an important and controversial part of polar history, its uses and misuses have so far received little attention from professional historians. Especially mobile nuclear reactors, as deployed for instance on the Antarctic continent, played an important role in the conquest of the polar regions. The Antarctic case presented here allows to illustrate the large diversity of issues involved in the American mobile nuclear reactor programme, ranging from economic considerations, over military strategy, to environmental and health concerns. During several decades, mobile nuclear power reactors were considered a cheap and clean solution, yet as this essay shows, history proved otherwise. None of the economic targets were met and in the case of the Antarctic reactor, repeated failures and even radioactive leakages lead finally to the shutdown of the whole programme. ; Même si l'énergie nucléaire joue un rôle important et controversé dans l'histoire polaire, son usage et son mésusage ont reçu très peu d'attention de la part des historiens. Les réacteurs nucléaires mobiles en particulier, tels qu'ils ont été mis en oeuvre sur le continent antarctique, ont occupé une fonction cruciale dans la conquête des régions polaires. Le cas antarctique présenté ici permet d'illustrer la grande diversité des éléments invoqués dans le programme étatsunien de réacteurs nucléaires mobiles, allant de considérations économiques, en passant par la stratégie militaire, à des inquiétudes environnementales et de santé publique. Pendant plusieurs décennies, les réacteurs nucléaires mobiles ont été considérés une solution peu couteuse et propre, mais comme nous allons arguer ci-dessous, l'histoire en a voulu autrement. Aucun des objectifs économiques ne fut atteint et dans le cas du réacteur en Antarctique, de nombreuses coupures et même des fuites radioactives ont amené enfin à l'abandon du programme.

The writings of the Indian Diaspora have received a great deal of attention and critical acclaim throughout the world. Rohinton Mistry is a well renowned author in the contemporary commonwealth literature and occupies a significant place among the writers of Indian Diaspora. Even though he is settled in Canada; it is his upbringing in Mumbai that reflects in all his writings. The distinct Mumbai culture, particularly the Parsee way of life, the people of the city and even the politics of India are major themes in his novels. Rohinton Mistry as a writer of Diaspora has carved a niche for himself. His works such as: "Tales from Firozsha Baag", "Such A Long Journey", "A Fine Balance" and "Family Matters";mark a new kind of writing, resulting from a fragmented, splintered world. As a Diasporic Parsi writer, very sensitively he has recalled his community's journey through time and history with a sense of loss and nostalgia. His books portray diverse facets of Indian socioeconomic life; as well as Parsi Zoroastrian life, customs, and religion. Many of his writings are markedly "Indo-nostalgic". Rohinton Mistry through his Diasporic discourse has well depicted his ancestral background, his community's engaged situation in a metropolis like Bombay and his deep attachment with and nostalgia for a world gone by. In this paper an attempt has been made to delineate diasporic discourse in the works of Rohinton Mistry. Although he is obsessed with the colonial and postcolonial experiences in India, we can find some traces of Canada in his literature. His characters dream of being integrated into, and accepted by, Canadian society on the one hand and on the other hand, these same characters are torn by an insatiable desire to be true to their native culture; to honor and cherish their own, distinct cultural identity.
