Authors: Noskoski Luís Eduardo Carvalho , Costa Nilson Luiz da , Oliveira Gabriel Nunes de , Dalcin Menigui Spanevello , Mabetana Kima Paulo Frederico 
Published: May 2024

Desde sua institucionalização, o Programa Nacional de Fortalecimento da Agricultura Familiar (PRONAF), se consolidou como o principal instrumento de política pública de apoio à agricultura familiar brasileira, possibilitando aos pequenos produtores investimentos, aumentando o volume produzido e os inserindo em mercados locais, regionais e globais. Além disso, o PRONAF é uma das políticas agrícolas mais pesquisadas no Brasil. Assim, o presente estudo tem como objetivo investigar o que vem sendo mostrado pelas pesquisas atuais sobre o PRONAF e como as políticas de financiamento do programa estão sendo efetivamente implementadas pelos agricultores familiares no estado do Rio Grande do Sul. A pesquisa foi realizada a partir da revisão sistemática da literatura na base de dados do Portal de Periódicos Capes, Scielo e Scopus, com recorte temporal dos últimos cinco anos, permitindo catalogar 13 artigos recentes discorrendo sobre o tema. A análise do PRONAF no estado do Rio Grande do Sul revelou sua atual tendência de financiar tanto a diversificação das produções quanto a expansão de monoculturas na agricultura familiar. Contudo, observou-se uma predominância do financiamento para a produção de commodities, o que embora beneficie alguns agricultores familiares, não atende adequadamente à heterogeneidade da classe produtora. Conclui-se que uma readequação da política pública é necessária para garantir benefícios equitativos a todos os agricultores familiares, destacando a necessidade de políticas que promovam a diversificação dos mercados para fortalecer os agricultores não inseridos nos mercados globais.

AbstractRecent advancements in the integration of nanoscale, single‐crystalline semiconductor ‘X’ on substrate ‘Y’ (XoY) for use in transistor and sensor applications are presented. XoY is a generic materials framework for enabling the fabrication of various novel devices, without the constraints of the original growth substrates. Two specific XoY process schemes, along with their associated materials, device and applications are presented. In one example, the layer transfer of ultrathin III–V semiconductors with thicknesses of just a few nanometers on Si substrates is explored for use as energy‐efficient electronics, with the fabricated devices exhibiting excellent electrical properties. In the second example, contact printing of nanowire‐arrays on thin, bendable substrates for use as artificial electronic‐skin is presented. Here, the devices are capable of conformably covering any surface, and providing a real‐time, two‐dimensional mapping of external stimuli for the realization of smart functional surfaces. This work is an example of the emerging field of “translational nanotechnology” as it bridges basic science of nanomaterials with practical applications.
Residual activity and proteasomal degradation of p.Ser298Pro sulfamidase identified in patients with a mild clinical phenotype of Sanfilippo A syndrome

Published: June 2011

AbstractMucopolysaccharidosis type IIIA (MPS IIIA, Sanfilippo syndrome) is a fatal inherited lysosomal storage disease accompanied by progressive neurologic degeneration. The gene underlying MPS IIIA, SGSH, encodes a lysosomal enzyme, N‐sulfoglucosamine sulfohydrolase (sulfamidase). Mutational analysis of a large cohort of MPS IIIA patients showed a correlation of the missense mutation p.Ser298Pro and a slowly progressive course of the disease. We report here on the expression of the mutant p.Ser298Pro sulfamidase in BHK cells retaining low residual activity. Pulse‐chase experiments showed that rapid degradation is responsible for the low steady state level of the mutant protein. Processing and secretion of p.Ser298Pro sulfamidase suggests that small amounts of the newly synthesized enzyme are transported to lysosomes. Most of the mutant sulfamidase exits the endoplasmic reticulum for proteasomal degradation. The ability to predict the clinical course of MPS IIIA in patients with the p.Ser298Pro mutation, as well as the residual enzymatic activity, and the reduced stability of the mutant sulfamidase suggest that this subgroup of patients is especially well suited to early sulfamidase replacement therapy or treatment with selective pharmacological chaperones. © 2011 Wiley‐Liss, Inc.
Polymerization shrinkage, stress, and degree of conversion in silorane‐ and dimethacrylate‐based dental composites
Authors: Xiong Jie , Sun Xiang , Li Yuncong , Chen Jihua 
Published: June 2011

AbstractTo compare two kind of resin‐based dental composites, the polymerization shrinkage, contraction stress (CS), and degree of conversion (DC) of four dimethacrylate‐based and one silorane‐based composite were investigated. To determine shrinkage, the composites were packed, respectively, into a cylindrical cavity in human teeth and imaged using X‐ray microcomputed tomography to determine the precise volume before and 30 min after photopolymerization. To determine CS, the sample was applied in a similarly sized cylinder in a universal testing machine and monitored for 30 min. FTIR spectroscopy was used to determine DC. The volumetric shrinkage (range: 1.1–3.1%) and maximum CS (range: 1.2–3.5 MPa) differed significantly among the tested composites but not the final DC (range: 62.3–69.1%). The silorane‐based composite displayed the lowest volumetric shrinkage and CS of all composites. No correlation was observed between the stress and volumetric shrinkage values of the dimethacrylate‐based composites. A moderate correlation was found between stress and DC (r = 0.836), which was significant at 20 and 40 s. The silorane‐based composite exhibited superior shrinkage behavior compared with conventional dimethacrylate composites with comparable polymerization kinetics. The CS was dependent on multiple variables, including the volumetric shrinkage, DC, and curing rate. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Organocatalytic Approach for the Syntheses of Corynantheidol, Dihydrocorynantheol, Protoemetinol, Protoemetine, and Mitragynine
Authors: Sun Xuefeng , Ma Dawei 
Published: June 2011

AbstractO‐Trimethylsilyl (TMS)‐protected diphenylprolinol‐catalyzed Michael addition of a functionalized alkylidene malonate and n‐butanal affords an aldehyde. This adduct can serve as the common intermediate for the assembly of secologanin tryptamine and dopamine alkaloids; this is demonstrated by the total syntheses of corynantheidol, dihydrocorynantheol, protoemetinol, and protoemetine, and the formal synthesis of mitragynine. The key steps include reductive amination of this aldehyde with tryptamine, condensation of this aldehyde with 4‐methoxytryptamine, condensation of dimethoxyphenethylamine with a lactone derived from this aldehyde, and subsequent Bischler–Napieralski cyclization and reduction.
The resource footprint of biobased products: a key issue in the sustainable development of biorefineries

Published: June 2011

AbstractThe multifunctionality of bioresources is a major opportunity for the future; it offers the ability to replace fossil‐related market demands in a carbon neutral way. However, the switchover to a biobased economy faces two main challenges in comparison with the current fossil‐based situation: biofeedstock requires an intensive cultivation step and furthermore there is a certain competition with the food chain which limits the amount of land available for new markets. So whilst biomass is seen as a ‘renewable’ resource, it is definitely not ‘gratuite’, inducing the need of an efficient cultivation and valorization. In this paper, a case study is executed to highlight that biorefining feedstock into a wide range of products is a thermodynamically efficient (81.1%) way of processing all molecules of the bioresources for specific purposes in different segments of the market demand. On the other hand, it is demonstrated in the second part of the paper that replacing fossils requires a certain amount of inputs from the Earth's crust causing additional thermodynamic losses in the production chain (15.3% efficient), which are quantified based on the resource footprint of the Cumulative Exergy Extracted from the Natural Environment (CEENE) methodology. A scenario assessment demonstrates the resulting tradeoff between the carbon footprint of bioproducts and the land, water, and minerals footprint; in the case study executed, 27% fossil resources are saved at the cost of 93% extra land, water and mineral input from the natural environment. © 2011 Society of Chemical Industry and John Wiley & Sons, Ltd
Polyphenolic Glycosides and Aglycones Utilize Opposing Pathways To Selectively Remodel and Inactivate Toxic Oligomers of Amyloid β

AbstractSubstantial evidence suggests that soluble prefibrillar oligomers of the Aβ42 peptide associated with Alzheimer's disease are the most cytotoxic aggregated Aβ isoform. Limited previous work has revealed that aromatic compounds capable of remodeling Aβ oligomers into nontoxic conformers typically do so by converting them into off‐pathway aggregates instead of dissociating them into monomers. Towards identifying small‐molecule antagonists capable of selectively dissociating toxic Aβ oligomers into soluble peptide at substoichiometric concentrations, we have investigated the pathways used by polyphenol aglycones and their glycosides to remodel Aβ soluble oligomers. We find that eleven polyphenol aglycones of variable size and structure utilize the same remodeling pathway whereby Aβ oligomers are rapidly converted into large, off‐pathway aggregates. Strikingly, we find that glycosides of these polyphenols all utilize a distinct remodeling pathway in which Aβ oligomers are rapidly dissociated into soluble, disaggregated peptide. This disaggregation activity is a synergistic combination of the aglycone and glycone moieties because combinations of polyphenols and sugars fail to disaggregate Aβ oligomers. We also find that polyphenolic glycosides and aglycones use the same opposing pathways to remodel Aβ fibrils. Importantly, both classes of polyphenols fail to remodel nontoxic Aβ oligomers (which are indistinguishable in size and morphology to Aβ soluble oligomers) or promote aggregation of freshly disaggregated Aβ peptide; thus revealing that they are specific for remodeling toxic Aβ conformers. We expect that these and related small molecules will be powerful chemical probes for investigating the conformational and cellular underpinnings of Aβ‐mediated toxicity.
Sequence‐Controlled Oligomers Fold into Nanosolenoids and Impart Unusual Optical Properties

AbstractControlled syntheses give unique block oligomers with alternating flexible ethylene glycol and rigid perylenetetracarboxylic diimide (PDI) units. The number of rigid units vary from n=1 to 10. PDI units were stitched together by using efficient phosphoramidite chemistry. The resulting oligomers undergo folding in most solvents, including chloroform. In their ground state, these folded oligomers were characterized by using Fourier transform ion cyclotron resonance mass spectrometry (FTICR‐MS), NMR spectroscopy, and electronic absorption spectroscopy. FTICR‐MS revealed the exact masses of these sequence‐controlled oligomers, which confirmed the chemical composition and validated the synthetic strategy. The NMR neighboring ring‐current effect (NRE) indicates the formation of cofacial π stacks; the stacked aromatic rings have nearly coaxial alignment akin to a nanosoleniod. Nanosolenoidal shielding in π stacks causes all aromatic protons to shift upfield, whereas NOE in a cyclic hetero‐chromophoric dimer supports a rotated, cofacial π‐stacking orientation separated by about 3.5 Å. Electron–phonon coupling is much stronger than excitonic coupling in these self‐folded PDI oligomers; thus, Franck–Condon factors dictate the observed spectral features in visible spectra. The absorbance spectrum exhibits weak hypochromism due to π stacking with increasing stacking units n. Finally, ab initio calculations support the experimental observations, indicating 3.5 Å cofacial spacing in which one molecule is rotated 30° from the eclipsed orientation and higher oligomers can adopt, without a compensating energy penalty, either the right/left‐handed helices or the 1,3‐eclipsed structures. Both theory and experiments validate the nano‐π‐solenoids and their novel photophysical properties.

Eutrophierung der Ostsee. Meeresverschmutzung und Meeresschutz
Authors: Nausch Günther 
Published: June 2011

AbstractDie Eutrophierung, d.h. die erhöhte Versorgung mit den Pflanzennährstoffen Stickstoff und Phosphor durch menschliche Aktivitäten in den Einzugsgebieten und ihre nachteiligen Folgen ist nach wie vor eines der wesentlichsten Probleme der Ostsee. Im Zeitraum 2001–2006 wurden im Mittel 30000 t Phosphor und 841000 t Stickstoff je Jahr eingetragen. Dies entspricht einer Zunahme der Phosphorbelastung in den letzten 100 Jahren um das 8fache, die Stickstoffbelastung hat sich im gleichen Zeitraum vervierfacht, was auch zu einer deutlichen Erhöhung der Nährstoffkonzentrationen in der Ostsee geführt hat. Der vorliegende Artikel beschreibt den gegenwärtigen Eutrophierungszustand der Ostsee sowie Schutz‐ und Sanierungsmaßnahmen, die das Ziel haben, das ökologische Gleichgewicht der Ostsee wiederherzustellen.

AbstractStrychnin, eines der giftigsten Alkaloide, hat Wissenschaftler seit seiner ersten Isolierung im Jahr 1818 fasziniert. Es dauerte über 130 Jahre bis die chemische Struktur zweifelsfrei gesichert werden konnte und weitere 7 Jahre bis zur ersten Totalsynthese durch Robert B. Woodward. Auch heute noch werden neue Synthesestrategien für diese faszinierend komplexe Verbindung entwickelt. Einige chemische Aspekte und persönliche Erfahrungen bei der Synthese Nr. 17 von 2010 werden berichtet.
