AbstractGalician presents an intriguing case of opaque phonologically-conditioned definite article allomorphy (PCA). Though Galician features in the general literature on PCA (Nevins 2011), there is a surprising lack of synchronic theoretical discussion of this specific pattern. The data appears to require allomorph selection arranged in a system of Priority (Mascaró 2005; Bonet et al. 2003; 2007). The pattern involves opaque segment ‘deletion’ and resyllabification, where segment deletion counterbleeds allomorph insertion along with morphologically-specific segmental changes. A Strict CV representational reanalysis is proposed in which there is no true allomorphy (no selection between competing underlying morphemes). All the forms are generated from a single underlying form, thereby undercutting PRIORITY.

Цель. Установить влияние неспецифического адреноблокатора карведилола на редокс-статус низкомолекулярных аминотиолов (цистеин, гомоцистеин, глутатион) в плазме крови при моделировании глобальной ишемии головного мозга у крыс. Методика. Нами была использована модель глобальной ишемии (пережатие общих сонных артерий с геморрагией длительностью 15 мин). Препарат вводили за 1 ч до операции. Уровни аминотиолов измеряли через 40 мин после начала реперфузии. Анализ уровня аминотиолов проводили методом жидкостной хроматографии. Результаты. Установлено, что у крыс, не подвергавшихся ишемии, карведилол в дозе 10 мг/кг вызывает рост редокс-статуса цистеина и глутатиона (в 3 и 3,5 раза соответственно по сравнению с контролем, p = 0,04 и p = 0,008) за счет увеличения их восстановленных форм. При ишемии данного эффекта не наблюдалось. Редокс-статус у крыс с ишемией на фоне карведилола (Цис = 0,85 ± 0,14%, Глн = 1,8 ± 0,7%, Гцис = 1,1 ± 0,8%) оставался таким же низким, как и у крыс с ишемией без введения карведилола (р > 0,8). Заключение. Полученный результат демонстрирует, что в условиях ишемии головного мозга карведилол не оказывает эффекта на гомеостаз аминотиолов плазмы крови, несмотря на выраженный антиоксидантный эффект в нормальных условиях. Aim. Effect of a nonspecific adrenergic antagonist carvedilol on the redox status of plasma low-molecular-weight aminothiols (cysteine, homocysteine, glutathione) was studied in rats with global cerebral ischemia (occlusion of common carotid arteries with hemorrhage). Methods. A model of global ischemia (occlusion of common carotid arteries with 15-min hemorrhage) was used. The drugs were administered one hour before the operation. Aminothiol levels were measured by HPLC with UV detection at 40 minutes after the onset of reperfusion. Results. Carvedilol 10 mg/kg increased the redox status of cysteine and glutathione in rats not exposed to ischemia (3 and 3.5 times, respectively, compared with the control, p = 0.04 and p = 0.008, respectively) but not of homocysteine, by increasing their reduced forms. However, this effect was not observed in ischemia. In rats with ischemia treated with carvedilol, the redox status (Cys = 0.85 ± 0.14%, GSH = 1.8 ± 0.7%, Hcys = 1.1 ± 0.8%) remained low similar to that in rats with ischemia not treated with carvedilol (p >0.8, 0.8, and 0.9, respectively). Conclusion. Carvedilol did not affect the homeostasis of blood plasma thiols in cerebral ischemia despite the pronounced antioxidant effect under the normal conditions.

Ischemic stroke (IS) and type 2 diabetes mellitus are factors that affect the homeostasis of low-molecularweight aminothiols (cysteine, homocysteine, glutathione etc.). It has already been shown that IS in the acute period led to a decrease a level of reduced forms of aminothiols, but it is not clear whether type 2 diabetes mellitus has a noticeable effect there. Objective: to reveal the features of homeostasis of aminothiols in patients with type 2 diabetes mellitus in acute IS. Material and methods. The study involved 76 patients with primary middle cerebral artery IS in the first 10–24 hours after development of neurological symptoms. Group 1 included 15 patients with IS and type 2 diabetes mellitus, group 2 — 61 patients with IS and stress hyperglycemia. Their total plasma levels of cysteine, homocysteine, and glutathione, their reduced forms, and redox status were determined at admission (in the first 24 hours after IS). Results. There was a decrease in the level of total glutathione level (1.27 vs. 1.65 μM, p = 0.021), as well as its reduced form (0.03 vs. 0.04 μM, p = 0.007) in patients with IS and type 2 diabetes mellitus. Patients with type 2 diabetes mellitus who had a low redox status of homocysteine (0.65–1.2%) and glutathione (0.7–2.0%) were also characterized by a decrease in total glutathione level (p = 0.02; p = 0.03). Conclusion. Thus, type 2 diabetes mellitus is associated with a decrease in the level of total glutathione in acute IS. Probably, type 2 diabetes mellitus is characterized by a particular relationship between the metabolism of homocysteine, glutathione and glucose. Therefore, the search for homocysteine-dependent approaches to correct glutathione metabolism in type 2 diabetes mellitus may be of interest as an adjuvant therapy for IS.

“On the Augment of Late Egyptian Verb Forms” -- It is shown that the augment which is characteristic of certain nominal verb forms of Late Egyptian – and survives in a few traces up until Coptic – contains none of those vowels that were regularly admitted at the beginning of Egyptian words. Rather, it must continue a wordinternal vowel /ǝ/ that moved into the initial position by a misdivision of the proclitic definite article, which frequently preceded participles and relative forms in speech. The same vowel [ǝ] occurred as an epenthetic sound before the preposition ‹r› /r/ ~ [ǝr], from which only ǝ remained after its consonantal body got lost. These phonetic insights prove that the Late Egyptian augment cannot derive from the Old Egyptian augment, as has been contended, but is a genuine innovation of Late Egyptian. Finally, the rise of unetymological initial vowels in various other nouns such as ⲉϭⲱϣ (“Nubian”) and ⲉϩⲟⲟⲩ (Bohairic for “day”) is explained.

Gender Agreement

We assessed monolingual Spanish and bilingual Spanish-Basque toddlers’ sensitivity to gender agreement in correct vs. incorrect Spanish noun phrases (definite article + noun), using a spontaneous preference listening paradigm. Monolingual Spanish-learning toddlers exhibited a tendency to listen longer to the grammatically correct phrases (e.g., la casa; “the house”), as opposed to the incorrect ones (e.g., * el casa). This listening preference toward correct phrases is in line with earlier results obtained from French monolingual 18-month-olds (van Heugten & Christophe, 2015). Bilingual toddlers in the current study, however, tended to listen longer to the incorrect phrases. Basque was not a source of interference in the bilingual toddler’s input as Basque does not instantiate grammatical gender agreement. Overall, our results suggest that both monolingual and bilingual toddlers can distinguish between the correct and incorrect phrases by 18 months of age; however, monolinguals and bilinguals allocate their attention differently when processing grammatically incorrect forms.

This article investigates the contact-induced reorganization of the possessive system in the Gallo-Romance dialects spoken from around the 12th century in the villages of Celle and Faeto in North Apulia and Guardia Piemontese in North-West Calabria. Gallo-Romance possessives exclude the article in the prenominal position, whereas in the Southern Italian dialects, possessives follow the noun preceded by the definite article. This original contrast is no longer visible in the varieties of Celle, Faeto and Guardia which changed the original prenominal position to the postnominal position combining with the article, except with kinship terms, preserving the original prenominal position. At the heart of contact phenomena, there are bilingualism and transfer mechanisms between the languages included in the complex knowledge of the speaker, suggesting a test bed for the treatment of language variation and parameterization. We propose an account of morpho-syntactic and interpretive properties of possessives, making use of the insights from the comparison of contact systems with prenominal (Franco-Provençal and Occitan varieties) and postnominal (Southern Italian dialects) possessives. The final part examines the distribution of possessives, tracing it back to the definiteness properties of DP and proposes a phasal treatment based on syntactic and interpretive constraints.

The problem of identifying correlations between catalytic and electrocatalytic processes is one of the fundamental problems of catalysis among “simple” organic substances, and the oxidation of CO and rCO2 is of great interest, since CO and CO2 are considered in pairs both during catalytic and electrocatalytic transformations. In the case of electrocatalysis, this analysis is important in the study of fuel cells. In this paper, we studied the correlation between the oxidation of reduced forms of CO2 (rCO2) under potentiodynamic-galvanoctatic electrochemical and open-circuit conditions of measurements on polycrystalline (pc)Pt in H2CO3. Periodic oscillations are revealed at the oxidation of Had and rCO2 on (pc)Pt. Quantum chemical calculations were carried out on the Pt13 cluster in order to identify the mechanisms of the rCO2 oxidation reaction. The correspondence in the energy parameters of the oxidation process of rCO2 under open-circuit conditions and electrochemical conditions is shown. The preliminary analysis of the system using density functional (DFT) calculations is carried out and the most stable systems that are based on Pt13 are found, namely rOH-Pt13-(CO)n, rOH-Pt13-(COH) and rOH-Pt13-(rCOOH). OH• species was chosen as the most likely candidate for the role of the oxidant for rCO2. Preliminary calculations for the expected reactions were carried out, and the optimal PES is revealed.
