Politica aparențelor, discursul prieteniei. Elaborarea convențiilor de aprovizionare a armatei ruse. Țara Românească, 1831-1832
Authors:   Institutul de Istorie „Nicolae Iorga”, Academia Română, Mateescu Bogdan
Published: May 2024

This paper deals with the way Russia and Wallachia signed a convention that regulated the supply of the Russian army, while it was stationed in the principality between 1828 and 1836. If establishing such a procedure through mutual agreement might appear as positive, the manner in which the act was validated reveals that diplomacy and reciprocity were in fact abandoned. In the end, what prevailed was the pretention on the Russian representatives to impose their will unilaterally, by breaching protocols that they themselves initiated in the winter of 1831-1832. Wallachian authorities were never notified as to who was to sign the convention on Russia’s behalf, and the principality’s legislative body (co-signer, alongside the Wallachian government) never even received a notification of Russia having signed the act. As far as we know from the Romanian archives, this did not take place, even though the convention was fully applied. Moreover, the legislative body saw itself in the rare position of not being granted a duplicate or copy of the convention, as even documents related to the matter were redrawn from its offices.
In an entire timeline of obeying orders under the guise of concluding an agreement, Wallachian lawmakers requested in vain that some formalities be respected. They asked the Russian governor to sign the convention, and later demanded the local government to hand over copies and related documents. What was supposed to be an act that would lead to the “stabilization of the country’s blessing, concluded in a joyful day for all Romanians”, was informally classified and obscured in archival files.

Authors: Cengiz Açıl Hande , Çelik Yılmaz Ayşe , Aygin Dilek
Published: May 2024

Morbid obesity is defined as having a body mass index (BMI) above 40 or having a BMI of 35 and comorbidities along with obesity. Bariatric surgeries can be grouped into three. These are restrictive surgeries, malabsorption (impairing absorption) surgeries, and both restrictive and malabsorption surgeries. In bariatric surgery, restrictive surgeries such as vertical band gastroplasty (VGB), adjustable gastric banding (AGB) surgeries, malabsorption surgeries such as biliopancreatic diversion (BPD)/duodenal switch (DS) surgeries, and both restrictive and malabsorption surgeries such as Roux-en-Y gastric bypass (RYGB) surgeries, are commonly performed. Post-bariatric surgery care should include a multidisciplinary team consisting of a surgeon, an endocrinologist, a psychiatrist, a dietitian, and a nurse specializing in bariatric surgery. Nursing care after obesity surgery is evaluated as early postoperative care (1-3 days) and late postoperative care. Close observation, careful and complete evaluation are important in the specialist nursing care of bariatric surgery patients. In bariatric surgery, patients are provided with routine post-operative nursing care such as oxygen and hemodynamic monitoring, pain management, mobilization, wound care, deep vein thrombosis prophylaxis, early and frequent ambulation, drain care, fluid balance nutrition, training, and emotional support.

La poétique de L’imitation de Jésus-Christ dans « Le torrent » d’Anne Hébert et le Journal de Saint-Denys Garneau : un élément dissonant
Authors: Plamondon Jean-François

Le présent article entend faire dialoguer le livre de piété du 16e siècle intitulé L’imitation de Jésus-Christ avec « Le torrent » d’Anne Hébert et le Journal de Saint-Denys Garneau. Si l’imaginaire des deux cousins se rencontre dans leurs oeuvres respectives, l’utilisation de L’imitation chez l’un et chez l’autre des deux écrivains pourrait bien conduire à un point de rupture, où la dissonance existentielle relèverait d’une esthétique de la « coïncidence des contraires », pour reprendre l’expression de Georges Bataille.

A excomunhão de Lutero
Authors: Wolff Elias
Published: May 2024

O artigo tem como objetivo analisar elementos históricos e teológicos na excomunhão de Lutero, perguntando sobre o sentido da sua continuidade hoje. Mostra que as controvérsias sobre as indulgências eram apenas o pano de fundo no qual Lutero propôs reformas na Igreja do seu tempo, o que não foi acatado e levou Leão X a excomungá-lo. Com o método da pesquisa de análise qualitativa da bibliografia sobre o tema proposto, o estudo aponta caminhos para uma revisão da excomunhão hoje. A conclusão é que os atuais progressos nas pesquisas históricas e teológicas, bem como no diálogo ecumênico, indicam possibilidades de reconhecer elementos da fé católica em Lutero e da fé de Lutero no documento papal que o excomunga, a Exsurge Domine. Muito da Reforma pode ser acolhida como herança comum para católicos e protestantes, possibilitando hoje um melhor entendimento da pessoa de Lutero e de suas Teses, o que cria bases para uma revisão e mesmo de declaração de nulidade da excomunhão para os dias atuais.

Brain age has limited utility as a biomarker for capturing fluid cognition in older individuals
Authors: Tetereva Alina , Pat Narun
Published: May 2024

One well-known biomarker candidate that supposedly helps capture fluid cognition is Brain Age, or a predicted value based on machine-learning models built to predict chronological age from brain MRI. To formally evaluate the utility of Brain Age for capturing fluid cognition, we built 26 age-prediction models for Brain Age based on different combinations of MRI modalities, using the Human Connectome Project in Aging (n=504, 36–100 years old). First, based on commonality analyses, we found a large overlap between Brain Age and chronological age: Brain Age could uniquely add only around 1.6% in explaining variation in fluid cognition over and above chronological age. Second, the age-prediction models that performed better at predicting chronological age did NOT necessarily create better Brain Age for capturing fluid cognition over and above chronological age. Instead, better-performing age-prediction models created Brain Age that overlapped larger with chronological age, up to around 29% out of 32%, in explaining fluid cognition. Third, Brain Age missed around 11% of the total variation in fluid cognition that could have been explained by the brain variation. That is, directly predicting fluid cognition from brain MRI data (instead of relying on Brain Age and chronological age) could lead to around a 1/3-time improvement of the total variation explained. Accordingly, we demonstrated the limited utility of Brain Age as a biomarker for fluid cognition and made some suggestions to ensure the utility of Brain Age in explaining fluid cognition and other phenotypes of interest.
Alasemenia, the earliest ovule with three wings and without cupule
Authors: Wang Deming , Yang Jiangnan , Liu Le , Zhou Yi , Xu Peng , Qin Min , Huang Pu
Published: May 2024

The ovules or seeds (fertilized ovules) with wings are widespread and especially important for wind dispersal. However, the earliest ovules in the Famennian of the Late Devonian are rarely known about the dispersal syndrome and usually surrounded by a cupule. From Xinhang, Anhui, China, we now report a new taxon of Famennian ovules, Alasemenia tria gen. et sp. nov. Each ovule of this taxon possesses three integumentary wings evidently extending outwards, folding inwards along abaxial side and enclosing most part of nucellus. The ovule is borne terminally on smooth dichotomous branches and lacks a cupule. Alasemenia suggests that the integuments of the earliest ovules without a cupule evolved functions in probable photosynthetic nutrition and wind dispersal. It indicates that the seed wing originated earlier than other wind dispersal mechanisms such as seed plume and pappus, and that three- or four-winged seeds were followed by seeds with less wings. Mathematical analysis shows that three-winged seeds are more adapted to wind dispersal than seeds with one, two or four wings under the same condition.

Somatic genetic heterogeneity resulting from post-zygotic DNA mutations is widespread in human tissues and can cause diseases, however few studies have investigated its role in neurodegenerative processes such as Alzheimer’s Disease (AD). Here we report the selective enrichment of microglia clones carrying pathogenic variants, that are not present in neuronal, glia/stromal cells, or blood, from patients with AD in comparison to age-matched controls. Notably, microglia-specific AD-associated variants preferentially target the MAPK pathway, including recurrent CBL ring-domain mutations. These variants activate ERK and drive a microglia transcriptional program characterized by a strong neuro-inflammatory response, both
in vitro
and in patients. Although the natural history of AD-associated microglial clones is difficult to establish in human, microglial expression of a MAPK pathway activating variant was previously shown to cause neurodegeneration in mice, suggesting that AD-associated neuroinflammatory microglial clones may contribute to the neurodegenerative process in patients.
CircCamsap1 is dispensable for male fertility in mice
Authors: Zhang Shu , Li Haojie , Jiang Wei , Chen Xia , Zhou Han , Wang Chang , Kong Hao , Shi Yichao , Shi Xiaodan
Published: May 2024

Background

Circular RNAs (circRNAs) are a large class of RNAs present in mammals. Among these, circCamsap1 is a well-acknowledged circRNA with significant implications, particularly in the development and progression of diverse tumors. However, the potential consequences of circCamsap1 depletion in vivo on male reproduction are yet to be thoroughly investigated.

Methods

The presence of circCamsap1 in the mouse testes was confirmed, and gene expression analysis was performed using reverse transcription quantitative polymerase chain reaction. CircCamsap1 knockout mice were generated utilizing the CRISPR/Cas9 system. Phenotypic analysis of both the testes and epididymis was conducted using histological and immunofluorescence staining. Additionally, fertility and sperm motility were assessed.

Results

Here, we successfully established a circCamsap1 knockout mouse model without affecting the expression of parental gene. Surprisingly, male mice lacking circCamsap1 (circCamsap1−/−) exhibited normal fertility, with no discernible differences in testicular and epididymal histology, spermatogenesis, sperm counts or sperm motility compared to circCamsap1+/+ mice. These findings suggest that circCamsap1 may not play an essential role in physiological spermatogenesis. Nonetheless, this result also underscores the complexity of circRNA function in male reproductive biology. Therefore, further research is necessary to elucidate the precise roles of other circRNAs in regulating male fertility.

Endoglycosidase and Glycoamidase Release of N‐Linked Glycans
Authors: Freeze Hudson H. , Kranz Christian
Published: November 2010

Nearly all proteins entering the lumen of the endoplasmic reticulum (ER) become glycosylated en route to a cellular organelle, the plasma membrane, or the extracellular space. Many glycans can be attached to proteins, but the most common are the N‐linked glycans (oligosaccharides). These chains are added very soon after a protein enters the ER, but they undergo extensive remodeling (processing), especially in the Golgi. Processing changes the sensitivity of the N‐glycan to enzymes that cleave entire sugar chains or individual monosaccharides, which also changes the migration of the protein on SDS gels. These changes can be used to indicate when a protein has passed a particular subcellular location. This unit details some of the methods used to track a protein as it trafficks from the ER to the Golgi toward its final location. Curr. Protoc.

Analysis of Protein Prenylation In Vitro and In Vivo Using Functionalized Phosphoisoprenoids
Authors: Nguyen Uyen T.T. , Wu Yaowen , Goodall Andrew , Alexandrov Kirill
Published: November 2010

Post‐translational modifications (PTMs) expand the number of protein isoforms in eukaryotic proteome by orders of magnitude. Protein modification with isoprenoid lipids is a common PTM affecting hundreds of proteins controlling the transport of information and materials into, through, and out of the eukaryotic cell. In this modification, a soluble phosphoisoprenoid such as farnesyl (C15) or geranylgeranyl (C20) pyrophosphate moiety is recruited by one of three protein prenyltransferases to covalently modify a C‐terminal cysteine(s) in a target protein. The three mammalian prenyltransferases are farnesyltransferase (FTase), geranylgeranyltransferase type I (GGTase I), and Rab geranylgeranyl transferase (also termed geranylgeranyltransferase type II ‐ GGTase II). In this unit, synthetic isoprenoids conjugated to either a fluorophore or biotin group are used to assay the activity of protein prenyltransferases in vitro or to affinity tag prenylatable proteins in cell lysates. These protocols and their modifications can be used to study the mechanisms of protein prenylation, identify prenylation targets, and characterize inhibitors of protein prenyltransferases in vitro and in vivo.

Published: November 2010

Mass spectrometry is an indispensable tool for peptide and protein analysis owing to its speed, sensitivity, and versatility. It can be used to determine amino acid sequences of peptides, and to characterize a wide variety of post‐translational modifications such as phosphorylation and glycosylation. Mass spectrometry can also be used to determine absolute and relative protein quantities, and can identify and quantify thousands of proteins from complex samples, which makes it an extremely powerful tool for systems biology studies. The main goals of this unit are to familiarize peptide and protein chemists and biologists with the types of mass spectrometers that are appropriate for the majority of their analytical needs, to describe the kinds of experiments that can be performed with these instruments on a routine basis, and to discuss the kinds of information that these experiments provide.

Moral disengagement in self‐reported and peer‐nominated school bullying
Authors: Obermann Marie‐Louise
Published: November 2010

This study examined the relation between moral disengagement and different self‐reported and peer‐nominated positions in school bullying. The aims of this study were to (1) investigate moral disengagement among children for whom self‐reported and peer‐nominated bully status diverged and (2) compare levels of disengagement among self‐reported and peer‐nominated pure bullies, pure victims, bully–victims, and children not involved in bullying. A sample of 739 Danish sixth grade and seventh grade children (mean age 12.6) was included in the study. Moral disengagement was measured using a Danish version of the Moral Disengagement Scale and bullying was measured using both self‐reports and peer nominations. Results revealed that both self‐reported and peer‐nominated bullying were related to moral disengagement, and that both pure bullies and bully–victims displayed higher moral disengagement than outsiders. Discrepancies between self‐reported and peer‐nominated bullying involvement indicates that a person's social reputation has a stronger association with moral disengagement than so far expected. Implications are discussed, highlighting the importance of further research and theory development. Aggr. Behav. 37:133–144, 2011. © 2010 Wiley‐Liss, Inc.

The biocompatibility of undoped and n‐type silicon nanowires (SiNWs), synthesized by metal‐catalyzed chemical vapor deposition, was investigated in vitro, and compared with that for SiO2‐coated silicon wafers. In cell interaction studies, L929 mouse fibroblast cells were used, in which MTT assay, AO/PI dye staining, cell proliferation/growth, and changes in cell adhesion/morphology on the surfaces were applied and investigated. Heamocompatibility of these materials were also tested. No significant cytotoxic effects were observed for either the undoped or for the n‐type phosphorus‐doped SiNWs. The cells on the nanowires exhibit high viability, normal nuclear, and morphological structure. They have shown no considerable negative blood response with respect to the control.

Bulk heterojunction solar cells based on blends of poly(3‐hexylthiophene) (P3HT) and phenyl‐C61‐butyric acid methyl ester (PC61BM) are fabricated using self‐assembled P3HT nanowires in a marginal solvent without post‐treatments. The interconnected network structures of self‐organized P3HT nanowires create continuous percolation pathways through the active layer and contribute to enhanced carrier mobility. The morphology and photovoltaic properties are studied as a function of ageing time of the P3HT precursor solution. Optimal photovoltaic properties are found at 60 h ageing time, which increases both light absorption and charge balance. Multilayered solar cells with a compositionally graded structure are fabriacted using preformed P3HT nanowires by inserting a pure P3HT donor phase onto the hole‐collecting electrode. Applying optimized annealing conditions to the P3HT buffer layer achieves an enhanced hole mobility and a power conversion efficiency of 3.94%. The introduction of a compositionally graded device structure, which contains a P3HT‐only region, reduces charge recombination and electron injection to the indium tin oxide (ITO) electrode and enhances the device properties. These results demonstrate that preformed semiconductor nanowires and compositionally graded structures constitute a promising approach to the control of bulk heterojunction morphology and charge‐carrier mobility.
Immobilized copper catalyst for atom transfer radical addition and polymerization
Authors: Wang Lin , Yan Xinhua , Fu Zhifeng , Dai Yun , Shi Yan
Published: November 2010

A novel multidentate amine grafted on silica gel and magnetic microsphere was prepared. Its chemical structure was confirmed by C13 NMR, XPS and FTIR, and the nitrogen content was determined by elemental analysis. It was also used as a ligand for CuCl and successfully catalyzed the atom transfer radical addition of both carbon tetrachloride (CCl4) to methyl methacrylate and methyl trichloroacetate to styrene, repeatedly. The conversion and purity of the product were determined through gas chromatography and 1H NMR, respectively. The immobilized copper catalyst complex was also used in atom transfer radical polymerization of styrene initiated by 1,1,1,3‐tetrachloro‐3‐phenylpropane and methyl methacrylate initiated by methyl 2‐methyl‐2,4,4,4‐tetrachlorobutyrate, respectively. Although the polymerization took place successfully, it did not proceed in a controlled fashion. Copyright © 2010 John Wiley & Sons, Ltd.
Nanoparticle emissions from biofuelled vehicles—their characteristics and impact on the number‐based regulation of atmospheric particles
Authors: Kumar Prashant , Robins Alan , ApSimon Helen
Published: November 2010

The transport sector is the dominant source of nanoparticles in the urban atmosphere. It is also responsible for about 20–25% of current global CO2 emissions, a figure that is expected to grow to about 30–50% by 2050 (Fuglestvedt et al., 2008). One option to counter this trend and contribute to the attainment of carbon emission reduction targets is the use of biofuels in road vehicles. This leads to a reduction in CO, CO2 and particle mass emissions, though particle number emissions may increase. This article discusses the potential impact of the particle number concentrations derived from biofuel vehicles on existing regulatory concerns over atmospheric nanoparticles.

Published: November 2010

The structures of small, robust metal clusters on a solid support were determined by a combination of spectroscopic and microscopic methods: extended X‐ray absorption fine structure (EXAFS) spectroscopy, scanning transmission electron microscopy (STEM), and aberration‐corrected STEM. The samples were synthesized from [Os3(CO)12] on MgO powder to provide supported clusters intended to be triosmium. The results demonstrate that the supported clusters are robust in the absence of oxidants. Conventional high‐angle annular dark‐field (HAADF) STEM images demonstrate a high degree of uniformity of the clusters, with root‐mean‐square (rms) radii of 2.03±0.06 Å. The EXAFS OsOs coordination number of 2.1±0.4 confirms the presence of triosmium clusters on average and correspondingly determines an average rms cluster radius of 2.02±0.04 Å. The high‐resolution STEM images show the individual Os atoms in the clusters, confirming the triangular structures of their frames and determining OsOs distances of 2.80±0.14 Å, matching the EXAFS value of 2.89±0.06 Å. IR and EXAFS spectra demonstrate the presence of CO ligands on the clusters. This set of techniques is recommended as optimal for detailed and reliable structural characterization of supported clusters.
Study on corrosion rate of carbon steel pipe under turbulent flow conditions
Authors: Slaimana Qasim J. M. , Hasan Basim O.
Published: November 2010

The effect of time (or corrosion products formation) on corrosion rate of carbon steel pipe in aerated 0.1 N NaCl solution under turbulent flow conditions was investigated. Tests were conducted using electrochemical polarisation technique by determining the limiting current density of oxygen reduction in Reynolds number (Re) range of 15 000 to 113 000 and temperature range of 30–60°C. The effect of corrosion products formation on the friction factor increase was studied and discussed. Empirical correlations for limiting current density as a function of Re were obtained at various solution temperatures for clean surface and for corroded surface. It was found that formation of corrosion products with time decreases the corrosion rate at low Re and temperature, while it increases the corrosion rate at high Re and temperature. As the corrosion products formed the surface roughness increased leading to increase the friction factor depending on temperature, Re, and corrosion rate.

On a analysé l'effet du temps (ou la formation de produits de corrosion) sur la vitesse de corrosion d'un tuyau d'acier au carbone dans une solution 0.1 N NaCl aérée dans des conditions d'écoulement turbulent. Des essais ont été réalisés à l'aide de la technique de polarisation électrochimique en déterminant la densité de courant limité de la réduction de l'oxygène dans l'écart de nombres de Reynolds de 15000 à 113000 et dans l'échelle de température de 30°C à 60°C. L'effet de la formation de produits de corrosion sur l'augmentation du facteur de frottement a été étudié et discuté. Les corrélations empiriques pour la densité de courant limité comme fonction du nombre de Reynolds ont été obtenues à diverses températures de solution pour une surface propre et une surface corrodée. On a découvert que la formation de produits de corrosion avec le temps réduit la vitesse de corrosion à une température et un nombre de Reynolds bas tout en augmentant la vitesse de corrosion à une température et nombre de Reynolds élevés. Pendant que les produits de corrosion se formaient, la rugosité de la surface augmentait, ce qui a mené à une augmentation du facteur de frottement selon la température, le nombre de Reynolds et la vitesse de corrosion. © 2010 Canadian Society for Chemical Engineering
A framework for modeling and supporting data transformation services over data and knowledge grids with real‐time bound constraints
Authors: Cuzzocrea A.
Published: November 2010

Data and Knowledge Gridsrepresent emerging and attracting application scenarios forGrid Computing, and pose novel and previously unrecognized challenges to the research community. Basically, Data and Knowledge Grids are found on high‐performanceGrid infrastructures, and add to the latter meaningful data‐ and knowledge‐oriented abstractions and metaphors that perfectly marry with innovative requirements of modern complexIntelligent Information Systems. To this end,Service‐oriented Architectures and Paradigmsare the most popular for Grids, and on the whole represent an active and widely recognized area of Grid Computing research. In this paper, we introduce the so‐calledGrid‐based RTSOA frameworks, which essentially combine Grid Computing withreal‐timeservice management and execution paradigms, and place emphasis for novel research perspectives in data‐intensivee‐science Grid applications onreal‐time bound constraints. Grid‐based RTSOA frameworks are then specialized to the particular context ofData Transformationservices over Grids, which play a relevant role for both Data and Knowledge Grids. Finally, we complete the main contribution of this paper with a rigorous theoretical model for efficiently supporting Grid‐based RTSOA frameworks, with particular emphasis on the context of Data Transformation services over Grids, along with its comprehensive experimental assessment and analysis.
