Old Venetan varieties display different forms of third person subject pronouns. In particular, the reduced monosyllabic and asyllabic forms are stronglyrelated to the expletive subject function. Even if the reduced forms do not have the same distribution of subject clitics in Modern Venetan, it can be argued that these forms have become clitics before the other pronouns. The article takes into consideration the syntax of expletive subjects in Old Venetan in relation to the rise of subject clitics in these varieties.

It was found that ischemic stroke (IS) results in decreased levels of a number of reduced forms of low molecular weight aminothiols (LMWTs). The study was aimed to assess the impact of type 2 diabetes mellitus (Т2D) on the total content, reduced forms and redox status of LMWTs in patients with IS. A total of 175 patients with IS in the internal carotid artery basin (the average age was 62 (55–69)) years) were assessed, who were admitted to the Center within the first 10–24 h since the onset of neurological disorder. The index group included 68 patients with IS and T2D (males made up 41.2%). The comparison group consisted of 107 patients with IS and stress hyperglycemia (males made up 57%), and the control group included 31 non-diabetic patients with chronic cerebrovascular disease (CCVD) (males made up 54.8%). The admission plasma levels of LMWTs were assessed by liquid chromatography in all patients. It was found, that IS in patients with T2D was associated with the rapid decrease in total cysteine (tCys), total glutathione (tGSH), total homocysteine (tHcy), reduced glutathione (rGSH), and glutathione redox status (GSH RS), along with the increase in cysteine redox status (Cys RS) and homocysteine redox status (Hcy RS). In contrast to patients with stress hyperglycemia developing during the acute period of IS, patients with T2D had lower tCys, tGSH, and tHcy levels. Thus, GSH RS of 4.06% or lower in the first 24 hours after the IS in patients with T2D was a predictor of poor functional outcome (mRS score was 3 or more 3 weeks after IS).

Fruits are excellent sources of essential vitamins and health-boosting minerals. Recently, regulation of fruit ripening by both internal and external cues for the improvement of fruit quality and shelf life has received considerable attention. Rosmarinic acid (RA) is a kind of natural plant-derived polyphenol, widely used in the drug therapy and food industry due to its distinct physiological functions. However, the role of RA in plant growth and development, especially at the postharvest period of fruits, remains largely unknown. Here, we demonstrated that postharvest RA treatment delayed the ripening in tomato fruits. Exogenous application of RA decreased ripening-associated ethylene production and inhibited the fruit color change from green to red based on the decline in lycopene accumulation. We also found that the degradation of sucrose and malic acid during ripening was significantly suppressed in RA-treated tomato fruits. The results of metabolite profiling showed that RA application promoted the accumulation of multiple amino acids in tomato fruits, such as aspartic acid, serine, tyrosine, and proline. Meanwhile, RA application also strengthened the antioxidant system by increasing both the activity of antioxidant enzymes and the contents of reduced forms of antioxidants. These findings not only unveiled a novel function of RA in fruit ripening, but also indicated an attractive strategy to manage and improve shelf life, flavor, and sensory evolution of tomato fruits.

This article analyses the factors influencing the process of input-intake conversion and focuses on the effect of “reduced forms” on English as a Second Language (ESL) learners’ listening comprehension. The Input Hypothesis, the Noticing Hypothesis, the input-intake relationship, and the factors influencing the input-intake relationship are critically reviewed and analyzed. The empirical study of Brown and Hilferty [1] is reviewed and discussed to show reduced forms’ influence on ESL learners’ listening comprehension. The results prove that integrating reduced forms into ESL lessons is both necessary and meaningful for improving students’ listening comprehension ability.

AbstractBats are renowned for their sophisticated echolocation. However, recent research has indicated that bats may be less reliant on echolocation than has long been assumed. To test the hypothesis that bats reduce their use of echolocation to avoid eavesdropping by conspecifics, we deployed miniature tags that recorded ultrasound and accelerations on 10 wild hoary bats (Lasiurus cinereus) for one or two nights. This resulted in 997 10-s recordings. Bats switched between periods predominated by their typical high-intensity echolocation, or periods predominated by micro calls (unusually short, quiet calls), or no detectable calls (“silence”). Periods of high-intensity echolocation included high rates of feeding buzzes, whereas periods of micro calls and silence included high rates of social interactions with other bats. Bats switched back to high-intensity echolocation during actual social interactions. These data support the hypothesis that bats use reduced forms of echolocation and fly in silence to avoid eavesdropping from conspecifics, perhaps in the context of mating-related behavior. They also provide the strongest demonstration to date that bats fly for extended periods of time without the use of echolocation.

Objective. Aminothiols (glutathione (GSH), cysteinylglycine (CG)) may play an important role in the pathogenesis of coronavirus disease 2019 (COVID-19), but the possible association of these indicators with the severity of COVID-19 has not yet been investigated. Methods. The total content ( t ) and reduced forms ( r ) of aminothiols were determined in patients with COVID-19 ( n = 59 ) on admission. Lung injury was characterized by computed tomography (CT) findings in accordance with the CT0-4 classification. Results. Low tGSH level was associated with the risk of severe COVID-19 ( tGSH ≤ 1.5   μ M , mild vs. moderate/severe: risk   ratio   RR = 3.09 , p = 0.007 ) and degree of lung damage ( tGSH ≤ 1.8   μ M , CT < 2 vs. CT ≥ 2 : RR = 2.14 , p = 0.0094 ). The rGSH level showed a negative association with D-dimer levels ( ρ = − 0.599 , p = 0.014 ). Low rCG level was also associated with the risk of lung damage ( rCG ≤ 1.3   μ M , CT < 2 vs. CT ≥ 2 : RR = 2.28 , p = 0.001 ). Levels of rCG ( ρ = − 0.339 , p = 0.012 ) and especially tCG ( ρ = − 0.551 , p = 0.004 ) were negatively associated with platelet count. In addition, a significant relationship was found between the advanced oxidation protein product level and tGSH in patients with moderate or severe but not in patients with mild COVID-19. Conclusion. Thus, tGSH and rCG can be seen as potential markers for the risk of severe COVID-19. GSH appears to be an important factor to oxidative damage prevention as infection progresses. This suggests the potential clinical efficacy of correcting glutathione metabolism as an adjunct therapy for COVID-19.

The paper considers natural-climatic and anthropogenic factors that determine differences in the self-purification capacity of the Sevastopol Bay ecosystems (its western, central, eastern parts and the Yuzhnaya Bay) in relation to the reduced nitrogen forms (ammonium and nitrites) by calculating the assimilation capacity. The authors took into account the intensity of the input sources of the studied forms of nitrogen, the rate of excretion from the ecosystem, the dynamic situation in the studied water areas and in the entire bay as well as the location of recreational facilities. For the first time, the factors were assessed that provide additional input of reduced forms of nitrogen associated with hypoxia during summer water stratification in local deepened areas in the upper bottom sediment layer, taking into account their particle size distribution. Further, the authors considered accumulation of organic matter and its destruction due to oxidized nitrogen forms and formation of reduced forms thereof. The currents in the central and southern parts of the Sevastopol Bay were calculated using a hydrodynamic model. The calculation results correspond to the current system in the mentioned water areas of the bay according to in situ data at different wind situations in the region. According to the calculations, it is possible that under certain hydrometeorological situations additional amount of ammonium and nitrites would flow from the Yuzhnaya Bay into the central part of the Sevastopol Bay.

The process of catalytic hydrogenation of furfural diethyl acetal to ethyl furfuryl ether on the different catalysts (palladium, palladium-rhenium and copper-ruthenium on Sibunit in reduced forms) was studied. It was found that hydrogenation of the furan ring with the formation of THF diethyl acetal occurs on all the catalysts. Ethyl furfuryl ether becomes the main product while carrying on the second hydrogenation cycle on spent palladium catalyst (yield and selectivity up to 55 % and 85 %, respectively)

Basic sentences in Maōri have VSO constituent ordering, but the nominative argument can precede the verb in constructions that have sentence-initial Topics, Focused constituents, or negatives. In the constructions with pre-verbal nominatives there are restrictions on the tense-denoting particles that may be present. This chapter proposes that, except in the case of subject Topics, when a nominative expression precedes the verb of which it is an argument, it has raised to Spec, Fin/T within a CP domain where it is c-commanded by higher Tense. The structural analysis is developed in the terms of a cartographic approach, drawing in particular on proposals of Belletti (2015) as to reduced forms of cleft CPs and separating out distinctions in the locations of splits and hybrids involving Force and Finiteness in the left periphery.
