Abstract

Introduction: Increased urinary podocalyxin, a surrogate marker of podocyte detachment, has been shown in preeclampsia and eclampsia, but there is a paucity of data of the effect of normal pregnancy on its urinary excretion. We aimed to describe these changes in this pilot study.

Methods: Urine podocalyxin levels were measured in 115 pregnant women. Of these, 12 women were in the second trimester of gestation, 57 in the third trimester and 46 women were in labor.

Results: The median [IQR] urinary podocalyxin levels were 0.81 [0.27, 3.68], 0.92 [0.44, 5.49] and 64.7 [30.5, 106.3] ng/mg creatinine in the second trimester, third trimester, and during labor, respectively (p<0.0001). Patients with hematuria during labor had higher levels of urinary podocalyxin (128.6 [79.8, 169.6] ng/mg creatinine. There was a moderate correlation between gestational age and urinary podocalyxin levels (r=0.63, p<0.0001).

Conclusion: Urinary podocalyxin levels were low in normal pregnancies and increased significantly during labor and with hematuria.

Published: May 2022

In this study the as-deposited and heat treated at 423K of conductive blende graphene oxide (GO) / poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) thin films was prepared with different PEDOT:PSS concentration (0, 0.25, 0.5, 0.75 and 1.0)wt% on pre-cleaned glass substrate by spin coating technique. The energy dispersive X-ray Analysis (EDX) show the existence of higher amount of carbon and oxygen related to hydroxyl and carbonyl groups. X-ray diffraction (XRD) analysis of the as-deposited and annealed GO/PEDOT:PSS thin films blend indicated that the film prepared show broad peak around 8.24 corresponding to the (001) level refers to GO, this peak shifted to the lower 2θ with increasing PEDOT:PSS concentration. These results of Fourier transform infrared spectroscopy (FTIR) support the EDX measurement and confirm all the bonds of mixed compounds before and after annealing process. UV-visible spectra of the GO was registered for investigation the peak at ~ 224 nm along with the shoulder at ~ 260 nm. After blending ,there are a small shifts in the peaks locations toward the red shift wavelength with increase the concentrations of PEDOT:PSS, while after heat the peaks locations shift toward the blue shift wavelength.

Published: May 2022

Iraqi western desert is characterized by a widespread karst phenomenon and caves. Euphrates formation (Lower Miocene) includes enormous sinkholes and cavities within carbonate rocks that usually cause severe damages to any kind of engineering facilities built over it. 3D resistivity imaging techniques were used in detecting this kind of cavities in complicated lithology. The 3D view was fulfilled by collating seven 2D imaging lines. The 2D imaging survey was carried out by Dipole-dipole array with (n) factor and electrode spacing (a) of 6 and 2m respectively. The horizontal slices of the 3D models give a good subsurface picture. There are many caves in all directions (x, y, z). They reveal many small caves near the surface. These caves are clearly shown as points with highly variable resistivity values in slices of depths 0.80 m, 1.72 m, 2.78 m, and 3.99 m. The comparison between standard Least-square and robust constrain methods appeared that the inverse model produced by the robust constrain method has sharper and straighter boundaries. The results of both the two-dimensional and the three-dimensional resistive imaging models deal with almost the same spread of subsurface caves in the study area and show a high amount in number, especially in the upper part, white in color oolitic limestone, the second member of Euphrates Formation, of 3.8-8m depth. 2D and 3D resistivity imaging values have Standard Roof-mean square (RMS) error for large inverted models, this confirms that the study area is of high inhomogeneity. This heterogeneity resulted in a large variation in the resistivity of the rock component in addition to the large spread of caves near the surface.
Comparison Different Estimation Method for Reliability Function of Rayleigh Distribution Based On Fuzzy Lifetime Data
Authors: Taha Taha Anwar , Salman Abbas Najim 
Published: May 2022

In this study, we present different methods of estimating fuzzy reliability of a two-parameter Rayleigh distribution via the maximum likelihood estimator, median first-order statistics estimator, quartile estimator, L-moment estimator, and mixed Thompson-type estimator. The mean-square error MSE as a measurement for comparing the considered methods using simulation through different values for the parameters and unalike sample sizes is used. The results of simulation show that the fuzziness values are better than the real values for all sample sizes, as well as the fuzzy reliability at the estimation of the Maximum likelihood Method, and Mixed Thompson Method perform better than the other methods in the sense of MSE, so that we recommend to use this type of estimation.

Background:
There are a limited data examining the effects of prior hemorrhage on outcomes after stereotactic radiosurgery (SRS). The goal of this study was to identify risk factors for arteriovenous malformation (AVM) rupture and compare outcomes, including post-SRS hemorrhage, between patients presenting with ruptured and unruptured AVMs.

Methods:
A retrospective review of consecutive patients undergoing SRS for intracranial AVMs between 2009 and 2019 at our institution was conducted. Chi-square and multivariable logistic regression analyses were utilized to identify patient and AVM factors associated with AVM rupture at presentation and outcomes after SRS including the development of recurrent hemorrhage in both ruptured and unruptured groups.

Results:
Of 210 consecutive patients with intracranial AVMs treated with SRS, 73 patients (34.8%) presented with AVM rupture. Factors associated with AVM rupture included smaller AVM diameter, deep venous drainage, cerebellar location, and the presence of intranidal aneurysms (P < 0.05). In 188 patients with adequate follow-up time (mean 42.7 months), the overall post-SRS hemorrhage rate was 8.5% and was not significantly different between ruptured and unruptured groups (10.3 vs. 7.5%, P = 0.51). There were no significant differences in obliteration rate, time to obliteration, or adverse effects requiring surgery or steroids between unruptured and ruptured groups.

Conclusion:
Smaller AVM size, deep venous drainage, and associated intranidal aneurysms were associated with rupture at presentation. AVM rupture at presentation was not associated with an increased risk of recurrent hemorrhage or other complication after SRS when compared to unruptured AVM presentation. Obliteration rates were similar between ruptured and unruptured groups.

В статье рассмотрены возможности использования сапропеля и торфа в биологическом земледелии Чувашской Республики. Использование сапропеля увеличивает урожайность клубней картофеля в светло-серой лесной почве в 2,5 раза при внесении 50 т/га, и более, чем в два раза при внесении 30 т/га. При этом качество картофеля улучшается – содержание крахмала в клубнях картофеля существенно возрастает.
The article considers the possibilities of using sapropel and peat in biological agriculture of the Chuvash Republic. The use of sapropel increases the yield of potato tubers in light gray forest soil by 2.5 times when applying 50 t/ha, and more than twice when applying 30 t/ha. At the same time, the quality of potatoes improves – the starch content in potato tubers increases significantly.
Les considérations onto-gnoséologiques de Marr du point de vue de la méthodologie pragmatico-fonctionnelle
Authors: Leščak Oleg , Sitko Jurij , Simonato Elena , Sériot Patrick 
Published: May 2022

Les conceptions ontologiques de N. Marr ne s'accordaient pas vraiment avec ses conceptions gnoséologiques, ni ces dernières avec sa méthode de recherche. L'analyse pragmatico-fonctionnelle de la philosophie du langage de Marr permet de faire apparaître des échos des théories de W. von Humboldt, de H. Steinthal, des néo-platoniciens russes, de même que des fondateurs du fonctionnalisme et du pragmatisme en linguistique : A. Potebnja, H. Schuchardt, E. Cassirer, J. Baudouin de Courtenay, F. de Saussure, L. Ščerba, V. Mathesius, N. Troubetzkoy, etc. On a pu ainsi mettre en évidence certaines positions-clés de la philosophie du langage chez Marr :
Dans son ontologie : un psychosociologisme métaphysique (« de classe »), un dualisme transcendental, une combinaison de réalisme socio-économique et d'idéalisme ethno-sociologique, un activisme historique, un téléologisme objectif et un préformisme socio-ethnique, un organicisme, un émergentisme, un globalisme prospectif, un pluralisme et un empirisme rétrospectifs, un verbalisme, un sémanticisme, un aposteriorisme linguo-génétique et un antinaturalisme.
Dans sa gnoséologie : un objectivisme et un maximalisme, un phénoménologisme, un eïdétisme, une approche explicative, un herméneutisme, un diachronisme dynamique, un holisme, un anti-scientisme, anti-rationalisme et antiintellectualisme, un factualisme naturaliste.
Des deux points de vue, les conceptions de Marr sont totalement éclectiques. Une bonne partie des malentendus suscités par les jugements sur Marr proviennent de la non-compréhension de ses conceptions méthodologiques et de la tentative de les interpréter à partir de positions scientifiques, et non philosophico-méthodologiques. Marr n'était pas un linguiste, mais un philosophe du langage.
Actualité de Marr, ou permanence de l’utopie
Authors: Slodzian Monique 
Published: May 2022

Prenant appui sur des travaux récents, le présent article tente de questionner les interprétations successives de l'œuvre de Marr qui, selon nous, obscurcissent la compréhension du phénomène en son temps - le succès du marrisme résistera en effet silencieusement à l'anathème lancé en 1950 - et dissimulent son impact sur la durée. Il nous paraît en effet essentiel d'en montrer la résurgence actuelle sous d'autres formes et d'autres signatures.
La première partie s'attachera à repenser les influences philosophiques et linguistiques qui font du premier Marr un savant de son temps. La preuve de cette conformité est à trouver dans le consensus philosophique et idéologique qui règle le discours de ses contemporains les plus éminents dans le monde des sciences humaines et sociales, au-delà des frontières de la Russie. L'explicitation du consensus bâti sur l'héritage de la philosophie allemande (Leibniz, Kant, Hegel en particulier) devrait fournir des clés pour mieux comprendre pourquoi les idées de Marr ont continué de travailler la linguistique soviétique au-delà des années cinquante. Cela concerne le post-marrisme, bien étudié par ailleurs.
La deuxième partie s'attachera à étudier la conversion de Marr au marxisme-léninisme à travers la lecture de Engels et l'émergence de sa Nouvelle Théorie du langage, souvent présentée comme résultant d'une fracture idéologique. Nous verrons en quoi cet événement lui-même, abstraction faite de la conjoncture politique immédiate, peut être pensé dans la continuité avec la première période et dans quelle mesure le sociologisme et le logicisme caractéristiques de la linguistique soviétique des années soixante à quatre-vingt en constituent l'héritage. Dernière question : l'utopisme qui inspire aujourd'hui la furie ontologisante autour du Web mondial, et auquel participent directement des héritiers de Marr, ne donne-t-elle pas à ce dernier une actualité inattendue ? Il s'agira ici d'un néo-marrisme auquel la techno-science fournit un cadre propice.
La théorie linguistique de Hermann Paul : une conception «pragmatico-sémantique» de la syntaxe à la fin du 19e siècle.
Authors: Vanneufville Monique 
Published: May 2022

Dans ses Prinzipien der Sprachgeschichte de 1880, Hermann Paul, philologue allemand néo-grammairien (Junggrammatiker, 1846-1921), affirme un seul principe, communicatif, donc pragmatique, à l’origine de la langue et de son évolution historique des formes simples aux formes composées. Les actes langagiers entre individus sont source de changements progressifs. Ce principe historique général et universel concerne tous les éléments du langage et donc aussi la syntaxe de toutes les langues.
Si l’analyse paulienne de la phrase en sujet «psychologique», comme point de départ de la pensée, et prédicat «psychologique», comme aboutissement ou but de cette même pensée, renoue avec la sémiotique de tradition empiriste de la Popularphilosophie, et, au-delà d’elle ou à travers elle, avec le modèle encore plus ancien d’Aristote, modèle recouvert par le transcendantalisme kantien, l’analyse «psychologique» de Paul, reprise par le Suisse Sechehaye, élève de Saussure, en même temps qu’elle signe la rupture avec le modèle «logique» de la Grammaire de Port-Royal, annonce la linguistique moderne avec ses théories de l’énonciation et des actes de langage. De ce point de vue, les Principes pourraient bien représenter un passage obligé de l’histoire de la linguistique.
La psychanalyse en Russie dans les années 1920 et la notion de Sujet
Authors: Zarubina Tatiana 
Published: May 2022

L’histoire de la psychanalyse en Russie-URSS est un phénomène intéressant et étonnant en même temps. Les opinions sur cette histoire sont diverses, mais la plupart des scientifiques en Russie et en Occident pensent que la psychanalyse en Russie a disparu dans les années 1930 sous la pression idéologique et politique. Cet article avance au contraire l'hypothèse que sa disparition est le résultat d'une incompatibilité conceptuelle des représentations du Sujet.
Dans les années 1920 la psychanalyse en Russie est très répandue, mais elle connaît une scission : d’un côté continue à exister une psychanalyse clinique qui, sous la pression pratique et utilitaire («refonte de l’homme») de personnages officiels, se développe en pédologie ; de l’autre côté, apparaît le «freudisme», qui suscite des discussions intenses dans les sciences humaines. Le freudisme (c’est ainsi que la psychanalyse a été qualifiée en URSS, par analogie avec le «marxisme») a été compris comme la promesse, scientifiquement fondée, d’une refonte réelle (non littéraire) de l’homme sur la base d’une modification de sa conscience. Un autre trait particulier de la psychanalyse (ou plutôt du freudisme) des années 1920 en Russie est son alliance avec la réflexologie d’un côté (V. Bexterev, A. Zalkind) et avec le marxisme de l’autre (A. Lurija, B. Fridman).

Published: May 2022

OBJECTIVE
Piriform cortex (PC) is one of the critical structures in the epileptogenesis of mesial temporal lobe epilepsy (mTLE), but its role is poorly understood. The authors examined the utility of apparent diffusion coefficient (ADC; an MR-based marker of tissue pathology) of the PC as a predictor of seizure outcome in patients with mTLE undergoing MR-guided laser interstitial thermal therapy (MRgLITT).

METHODS
A total of 33 patients diagnosed with mTLE who underwent MRgLITT at the authors’ institution were included in the study. The 6-month postoperative seizure outcomes were classified using the International League Against Epilepsy (ILAE) system as good (complete seizure freedom, ILAE class I) and poor (seizure present, ILAE classes II–VI). The PC and ablation volumes were manually segmented from both the preoperative and intraoperative MRI sequences, respectively. The mean ADC intensities of 1) preablation PC; 2) total ablation volume; 3) ablated portion of PC; and 4) postablation residual PC were calculated and compared between good and poor outcome groups. Additionally, the preoperative PC volumes and proportion of PC volume ablated were examined and compared between the subjects in the two outcome groups.

RESULTS
The mean age at surgery was 36.5 ± 3.0 years, and the mean follow-up duration was 1.9 ± 0.2 years. Thirteen patients (39.4%) had a good outcome. The proportion of PC ablated was significantly associated with seizure outcome (10.16 vs 3.30, p < 0.05). After accounting for the variability in diffusion tensor imaging acquisition parameters, patients with good outcome had a significantly higher mean ADC of the preablation PC (0.3770 vs −0.0108, p < 0.05) and the postoperative residual PC (0.4197 vs 0.0309, p < 0.05) regions compared to those with poor outcomes. No significant differences in ADC of the ablated portion of PC were observed (0.2758 vs −0.4628, p = 0.12) after performing multivariate analysis.

CONCLUSIONS
A higher proportion of PC ablated was associated with complete seizure freedom. Preoperative and postoperative residual ADC measures of PC were significantly higher in the good seizure outcome group in patients with mTLE who underwent MRgLITT, suggesting that ADC analysis can assist with postablation outcome prediction and patient stratification.

OBJECTIVE
A recent comparative analysis between neurosurgical and endovascular treatments for craniocervical junction (CCJ) arteriovenous fistulas (AVFs) revealed better treatment outcomes in the neurosurgery group than in the endovascular group. This finding was attributed to the higher than expected rate of ischemic complications in the endovascular group than in the neurosurgery group (26% vs 7.7%, p = 0.037). The aim of the present study was to describe ischemic complications associated with treatments for CCJ AVFs.

METHODS
This descriptive study was authorized by the Neurospinal Society of Japan. Data from 97 consecutive patients with CCJ AVFs who underwent neurosurgical (n = 78) or endovascular (n = 19) treatment between 2009 and 2019 were collected from 29 centers. The primary endpoints were details on ischemic complications and their risk factors. Secondary endpoints were details on other complications.

RESULTS
Among all major complications, ischemic complications were the most common (11% of 97 patients), followed by hemorrhagic complications (7.2%), hydrocephalus (2.1%), and CSF leakage (2.1%). Ischemic complications included 8 spinal, 2 brainstem, and 1 cerebellar infarctions. Iatrogenic occlusion of the anterior or posterior spinal artery from the radiculomedullary or radiculopial arteries caused these complications. Ischemic complications resulted in neurological deficits, including motor paresis, sensory disturbances, and brainstem dysfunction. The modified Rankin Scale score was 3 or higher in 36% of patients with ischemic complications at the final follow-up of 23 months. Risk factors associated with ischemic complications were endovascular treatment (OR 4.3, 95% CI 1.1–16) and spinal feeding arteries (OR 3.8, 95% CI 1.03–14). Most of the other complications were addressed by additional treatment without permanent neurological deficits.

CONCLUSIONS
Among ischemic complications associated with treatments for CCJ AVFs, spinal infarctions were the most common and were mostly attributed to endovascular procedures for CCJ AVFs fed by spinal arteries. These results support the use of neurosurgery as the first-line treatment for CCJ AVFs.

Published: May 2022

Background: Despite tremendous advances in the treatment and management of stroke, restoring motor and functional outcomes after stroke continues to be a major clinical challenge. Given the wide range of approaches used in motor rehabilitation, several commentaries have highlighted the lack of a clear scientific basis for different interventions as one critical factor that has led to suboptimal study outcomes. Objective: To understand the content of current therapeutic interventions in terms of their active ingredients. Methods: We conducted an analysis of randomized controlled trials in stroke rehabilitation over a 2-year period from 2019-2020. Results: There were three primary findings: (i) consistent with prior reports, most studies did not provide an explicit rationale for why the treatment would be expected to work, (ii) most therapeutic interventions mentioned multiple active ingredients and there was not a close correspondence between the active ingredients mentioned versus the active ingredients measured in the study, and (iii) multimodal approaches that involved more than one therapeutic approach tended to be combined in an ad-hoc fashion, indicating the lack of a targeted approach. Conclusion: These results highlight the need for strengthening cross-disciplinary connections between basic science and clinical studies, and the need for structured development and testing of therapeutic approaches to find more effective treatment interventions.
