OBJECTIVEAneurysm wall enhancement (AWE) on 3D vessel wall MRI (VWMRI) has been suggested as an imaging biomarker for intracranial aneurysms (IAs) at higher risk of rupture. While computational fluid dynamics (CFD) studies have been used to investigate the association between hemodynamic forces and rupture status of IAs, the role of hemodynamic forces in unruptured IAs with AWE is poorly understood. The authors investigated the role and implications of abnormal hemodynamics related to aneurysm pathophysiology in patients with AWE in unruptured IAs.METHODSTwenty-five patients who had undergone digital subtraction angiography (DSA) and VWMRI studies from September 2016 to September 2017 were included, resulting in 22 patients with 25 IAs, 9 with and 16 without AWE. High-resolution CFD models of hemodynamics were created from DSA images. Univariate and multivariate analyses were performed to investigate the association between AWE and conventional morphological and hemodynamic parameters. Normalized MRI signal intensity was quantified and quantitatively associated with wall shear stresses (WSSs) for the entire aneurysm sac, and in regions of low, intermediate, and high WSS.RESULTSThe AWE group had lower WSS (p < 0.01) and sac-averaged velocity (p < 0.01) and larger aneurysm size (p < 0.001) and size ratio (p = 0.0251) than the non-AWE group. From multivariate analysis of both hemodynamic and morphological factors, only low WSS was found to be independently associated with AWE. Sac-averaged normalized MRI signal intensity correlated with WSS and was significantly different in regions of low WSS compared to regions of intermediate (p = 0.018) and high (p < 0.001) WSS.CONCLUSIONSThe presence of AWE was associated with morphological and hemodynamic factors related to rupture risk. Low WSS was found to be an independent predictor of AWE. Our findings support the hypothesis that low WSS in IAs with AWE may indicate a growth and remodeling process that may predispose such aneurysms to rupture; however, a causality between the two cannot be established.

OBJECTIVEThis study aimed to explore the contralesional homotopic functional plasticity in the brain of patients with unilateral temporal glioma.METHODSDemographic, neurocognitive, and resting-state functional MRI data were collected from 17 patients with temporal glioma (10 in the right lobe and 7 in the left lobe), along with 14 age- and sex-matched healthy controls. The amplitude of low-frequency fluctuation (ALFF) of the contralesional homotopic region and 2 control regions was examined. The region-of-interest–based analysis was used to determine the altered functional connectivity (FC) of the contralesional homotopic region, showing significantly different intrinsic regional brain activity between patients and controls. Partial correlation analysis was conducted to determine the association between the altered neural activity and behavioral characteristics.RESULTSCompared with controls, patients with right temporal glioma exhibited significantly increased ALFF in the contralesional homotopic hippocampus and parahippocampal region. In addition, the intrinsic regional activity in these regions was negatively correlated with the visuospatial score (r = −0.718, p = 0.045). Whole-brain FC analysis revealed significantly increased FC between the left hippocampus and parahippocampal regions and the left inferior temporal gyrus, and decreased FC between the left hippocampus and parahippocampal regions and the left inferior frontal gyrus. No significant changes were found in the 2 control regions.CONCLUSIONSContralesional homotopic regions are instrumental in the process of neural plasticity and functional compensation observed in patients with unilateral temporal glioma. The observed findings might be used to help preoperative evaluation or rehabilitation of postsurgical patients.
Single- versus 2-session Gamma Knife surgery for symptomatic midsize brain metastases: a propensity score–matched analysis
Authors: Yomo Shoji , Oda Kyota , Oguchi Kazuhiro 
Published: January 2020

OBJECTIVETwo-session Gamma Knife surgery (GKS) has recently been demonstrated to be an effective and less-invasive alternative for large brain metastases not treatable by microsurgical resection. This raises the clinical question of whether the 2-session GKS strategy further improves treatment outcomes for patients with symptomatic midsize brain metastases (2–10 cm3) as compared to single-session GKS. The present study aimed to compare the local therapeutic effects and toxicities of single-session and 2-session GKS for treating these lesions.METHODSPatients with focal neurological deficits attributable to midsize brain metastases who underwent upfront GKS during the period from 2010 to 2018 were retrospectively identified from an institutional database. Patients for whom both post-GKS imaging studies and neurological evaluations from outpatient visits were available were eligible. Using propensity score–matching (PSM) analysis, unique matched pairs which had a similar likelihood of receiving 2-session GKS were generated. The main outcome measure was a composite of imaging and/or neurological worsening of the lesion of interest. Functional improvement and overall survival (OS) were also compared between the 2 treatment arms.RESULTSIn total, 219 cancer patients with 252 symptomatic midsize brain metastases were eligible. Of these 252 tumors, 176 and 76 were treated with single- and 2-session GKS, respectively. After PSM, 68 pairs of tumors were obtained. The Gray test showed that 2-session GKS achieved a longer local progression–free interval than single-session GKS (1-year local control rate: 84% vs 53%; HR 0.31, 95% CI 0.16–0.63, p = 0.001). Two-session GKS was also associated with greater functional improvement in KPS scores (mean 18.3 ± 14.6 vs 12.8 ± 14.1, p = 0.040). The median OS did not differ significantly between single- and 2-session GKS (15.6 vs 24.7 months; HR 0.69, 95% CI 0.44–1.10, p = 0.11).CONCLUSIONSTwo-session GKS achieved more durable local tumor control and greater functional improvement than single-session GKS for patients with symptomatic midsize brain metastases, although there was no OS advantage.

Unfavourable environmental state of the reclaimed land requires to revise common methods of determining reclamation modes. Reclamation regimes should be chosen as part of complex facilities, depending on different physical, geographical and climatic conditions where the reclaimed land is located. This can be done by building catenary-facies models of watersheds. In our research we applied computer-based simulation methods of the functioning of the watershed facies catenas. The methods to be applied are based on the calculation of the moisture transfer processes by solving the differential equation of two-dimensional moisture movement in the soils and subsoils of the zones of aeration and complete saturation. The paper presents a catenary-facies model, its operation under natural conditions taking into account hydrotechnical ameliorations. The model allows to make forecast calculations of water regimes and of the watersheds facies productivity. We have developed a method of justification of environmental reclamation regimes by simulation of watershed facies catenas. Watershed facies have been classified according to their hydrothermal coefficient and the humidity ratio within watersheds of the forest-steppe zone of the Republic of Bashkortostan. There was revealed the integral dependence of relative crop capacity on soil washability of facies catenas. As a part of the study, there were found environmentally friendly meliorative regimes available for the conditions of the forest-steppe zone. The use of these regimes contributes to the minimum soil washability and the maximum crop capacity.

Syntactic and aspectual functions of Latvian verbal prefixes in Livonian
Authors: Jantunen Santra 
Published: January 2020

This paper presents an analysis of an assumed contact-induced change in the Livonian modes of expressing perfective aspect: the adoption of Latvian-origin verbal prefixes expressing perfective aspect. The main objective of this article is to determine whether long-standing contact between Livonian and Latvian has led to the introduction of verbal prefixes as both pure lexical elements and, in parallel, as markers of grammatical functions that distinguish Livonian from its closest cognate languages. The current study is based on the data derived from unpublished recordings and published written material representing spoken Livonian, already extinct as a first language in the traditional speech area.
There are a total of eleven Latvian-origin verbal prefixes in Livonian, a language which usually does not display this category. The prefixes are as follows: aiz-, ap-, at-, ie-, iz-, nuo-, pa-, pie-, pōr-, sa-, and uz-. In Latvian, most of these items can be used as bound verbal prefixes and also prepositions marking adverbial functions. In Livonian, these prefixes can be combined with both Livonian and Latvian verbs but, as a rule – except for pa- – they do not occur as prepositions. The frequency of their occurrence in the data varies considerably and, presumably, corresponds to the degree that a given prefix may derive perfective verbs. In fact, verbal prefixation can be considered, to some extent, a means for expressing perfective aspect in Livonian, thereby adding a secondary strategy to the inherent Finnic way of expressing aspectual oppositions, namely the object case alternation and verbal particles.
Mutual contacts and lexical relations among the Finnic varieties of western Ingria and northeastern Estonia
Authors: Björklöf Sofia 
Published: January 2020

The aim of this article is 1) to describe the historical language contact situation between the genetically closely related Finnic varieties of western Ingria, 2) to give examples of the numerous loanwords originating from mutual contacts among local Finnic varieties as well as areal diffusion, and 3) to discuss the method of investigating contacts and borrowing among closely related varieties. The data are taken from old dialectal materials published in vocabularies and dictionaries as well as preserved in archives. The words that are analysed and discussed etymologically in more detail are drawn from Vote, Ingrian, and Estonian. Although it is often difficult to confirm the direction of borrowing among closely related varieties, I seek to determine the direction of diffusion in the varieties whose development cannot be described merely in terms of a traditional binary family tree model. Examples of mutual borrowing between Vote, Ingrian, Estonian, and Finnish are presented. Estonian loanwords in Vote and Ingrian can usually be recognised by their distribution. Most vocabulary originating as loans (in Vote, Ingrian, and Estonian) has been borrowed from Finnish. Loans in both Vote and Estonian often have a distribution not only in Ingrian but also in Finnish. Because of the phonetic similarity of these varieties, the donor variety usually cannot be defined. Vote loanwords occur only sporadically in Ingrian and Estonian: they may also form a substratum.
The speakers of Finnic varieties in western Ingria used to live in old rural communities with long-term multilingualism, villages with a mixed population, and vague language boundaries. The arrival of new inhabitants from the countries, which ruled this area and the foundation of St. Petersburg in 1703 changed the ethnographic balance between different peoples in Ingria. This increased linguistic diversity and altered the hierarchy of the languages leading gradually to accelerating language and identity shift of the local peoples of Ingria.
Venäjän kielen vaikutus tverinkarjalan murteiden äännejärjestelmään
Authors: Novak Irina 
Published: January 2020

Tverinkarjala kuuluu varsinaiskarjalan eteläisiin murteisiin ja jakautuu kolmeen alamurteeseen: Tolmatšun, Vesjegonskin ja Djoržan jo sammuneeseen alamurteeseen. Tverinkarjalaiset ovat asuneet jo neljä vuosisataa venäläisten keskuudessa ja puhuneet venäjää pitkään. Venäjän kieli on vaikuttanut huomattavasti tverinkarjalan äännejärjestelmään sen kehityksen eri vaiheissa. Tästä johtuvat muutamat alamurteita toisistaan erottavat piirteet. Venäjän vaikutusta tverinkarjalan äännejärjestelmään on sekä vokaali- että konsonanttijärjestelmässä. 1) vokaalijärjestelmässä: pitkien uu-, yy-vokaalien ja u-, y-loppuisten diftongien jälkikomponenttien redusoituminen; sekundaaristen pitkien vokaalien esiintyminen; väljenevien diftongien fonemaattiset erot; Djoržan alamurteessa loppu- ja sisäheitto; 2) konsonanttijärjestelmässä: f- ja c-konsonanttifoneemien esiintyminen; sibilanttien distribuutio; geminaattojen kk, tt, pp, čč reduktio l-, r-, n-konsonanttien jäljessä; runsas liudentuminen ja kvalitatiivisen astevaihtelun epäproduktiivisuus.
Rajakarjalaismurteiden refleksiiviverbeistä
Authors: Koivisto Vesa 
Published: January 2020

Artikkeli käsittelee rajakarjalaismurteiden refleksiiviverbejä. Rajakarjalaismurteet ovat karjalan kielen suomenvaikutteinen alamurteisto. Artikkelin aineistona on n. 120 nauhatunnin laajuinen tekstimuotoinen Raja-Karjalan korpus. Käsiteltäviä refleksiiviverbien tyyppejä ovat refleksiivijohdokset sekä refleksiivitaivutus. Molempia tavataan niin karjalassa kuin suomessakin (refleksiivitaivutusta tosin vain suomen itämurteissa). Rajakarjalaismurteiden refleksiivitaivutus osoittautuu samankaltaiseksi kuin karjalan saarekemurteissa (ns. tytärkarjalaisissa murteissa) Sisä-Venäjällä, joskin se on paradigmaltaan vajaampi ja esiintymiseltään harvempi. Rajakarjalaismurteiden refleksiivijohdoksissa puolestaan tavataan joitakin karjalalle vanhastaan tuntemattomia morfologisia tyyppejä, jotka ovat selvää suomen kielen vaikutusta. Artikkelin aineistossa näkyy lisäksi rajakarjalaismurteille ominainen karjalan kahden päämurteen, varsinaiskarjalan ja livvinkarjalan, sekoittuneisuus.
