Syntactic change and the rise of transitivity : the case of the Polish and Ukrainian -no/-to construction

Artykuł przedstawia analizę różnic w rozwoju form predykatów z wykładnikami strony biernej w rodzaju nijakim -no/-to w języku polskim i ukraińskim. Przybranie cech tranzytywnych przez te formy czasownikowe łączy się tu ze zmianami w obrębie morfologii strony gramatycznej w obu językach. Pomimo powierzchniowych podobieństw różnice w dystrybucji konstrukcji z czasownikami zakończonymi na -no/-to we współczesnym języku polskim i ukraińskim wskazują, że gramatykalizacja morfemu strony biernej przebiegła według różnych scenariuszy w obu językach, implikujących zróżnicowanie w strukturze frazy czasownikowej vP, a także powstanie nowych możliwości przypisania cechy biernika.This paper analyzes the historical divergence of predicates marked with old passive neuter -no/-to in Polish and Ukrainian. It is argued that the locus of change leading to the rise of the transitivity property involved a rearrangement of morphologically-eroded voice morphology. Despite the surface similarity of the Polish and Ukrainian constructions, their divergent distribution in the modern languages indicates that grammaticalization of the old passive morpheme proceeded along different pathways, implicating the internal structure of vP, and creating new accusative case-assigning possibilities

Modalities of case assignment: The view from Lithuanian

This paper assesses two competing modalities for the assignment of morphological case. Arguments are provided from Lithuanian against the configurational strategy of Dependent Case (Marantz 1991, Baker 2015) and in favor of case assignment by functional heads (Chomsky 2000, 2001). The first argument comes from a series of Transitive Impersonal constructions in which accusative appears independently, in the absence of a higher, nominative-marked argument, so long as the predicate is two-place and caused, implicating v-Cause as the source of accusative. Further evidence for this analysis comes from the Inferential Evidential, an oblique-subject construction. While the Dependent Case strategy states that nominative automatically shifts to the object if not assigned to the subject, nominative objects are exceedingly rare in the Inferential Evidential, a fact that is entirely consistent with the local, feature-based theory of case advanced in this paper, which relates the appearance of nominative to the Agree relation with Tense

A New Argument for the Lexical Underspecification of Causers

This article shows how a systematic impersonalization alternation in Russian provides additional evidence for underspecification in argument structure. In the case of a large class of lexically causative verbs, the causer is realized either as a volitional Agent in the nominative case or as an oblique-marked, nonvolitional causer, depending on how the event is construed. A causative theory of accusative is advanced, according to which the mere presence of external causation is a sufficient condition for accusative licensing, including those cases that lack an external argument altogether. The analysis is extended to explain accusative preservation in the Icelandic “fate accusative” construction

Pioglitazone, Vitamin E, or Placebo for Nonalcoholic Steatohepatitis

Background Nonalcoholic steatohepatitis is a common liver disease that can progress to cirrhosis. Currently, there is no established treatment for this disease. Methods We randomly assigned 247 adults with nonalcoholic steatohepatitis and without diabetes to receive pioglitazone at a dose of 30 mg daily (80 subjects), vitamin E at a dose of 800 IU daily (84 subjects), or placebo (83 subjects), for 96 weeks. The primary outcome was an improvement in histologic features of nonalcoholic steatohepatitis, as assessed with the use of a composite of standardized scores for steatosis, lobular inflammation, hepatocellular ballooning, and fibrosis. Given the two planned primary comparisons, P values of less than 0.025 were considered to indicate statistical significance. Results Vitamin E therapy, as compared with placebo, was associated with a significantly higher rate of improvement in nonalcoholic steatohepatitis (43% vs. 19%, P=0.001), but the difference in the rate of improvement with pioglitazone as compared with placebo was not significant (34% and 19%, respectively; P=0.04). Serum alanine and aspartate aminotransferase levels were reduced with vitamin E and with pioglitazone, as compared with placebo (P Conclusions Vitamin E was superior to placebo for the treatment of nonalcoholic steatohepatitis in adults without diabetes. There was no benefit of pioglitazone over placebo for the primary outcome; however, significant benefits of pioglitazone were observed for some of the secondary outcomes.

Agreement Between Magnetic Resonance Imaging Proton Density Fat Fraction Measurements and Pathologist-assigned Steatosis Grades of Liver Biopsies from Adults with Nonalcoholic Steatohepatitis

Background & Aims We assessed the diagnostic performance of magnetic resonance imaging (MRI) proton density fat fraction (PDFF) in grading hepatic steatosis and change in hepatic steatosis in adults with nonalcoholic steatohepatitis (NASH) in a multi-center study, using central histology as reference. Methods We collected data from 113 adults with NASH participating in a multi-center, randomized, double-masked, placebo-controlled, phase 2b trial to compare the efficacy cross-sectionally and longitudinally of obeticholic acid vs placebo. Hepatic steatosis was assessed at baseline and after 72 weeks of obeticholic acid or placebo by liver biopsy and MRI (scanners from different manufacturers, at 1.5T or 3T). We compared steatosis estimates by PDFF vs histology. Histologic steatosis grade was scored in consensus by a pathology committee. Cross-validated receiver operating characteristic (ROC) analyses were performed. Results At baseline, 34% of subjects had steatosis grade 0 or 1, 39% had steatosis grade 2, and 27% had steatosis grade 3; corresponding mean PDFF values were 9.8%±3.7%, 18.1%±4.3%, and 30.1%±8.1%. PDFF classified steatosis grade 0–1 vs 2–3 with an area under the ROC curve (AUROC) of 0.95 (95% CI, 0.91–0.98), and grade 0–2 vs grade 3 steatosis with an AUROC of 0.96 (95% CI, 0.93–0.99). PDFF cut-off values at 90% specificity were 16.3% for grades 2–3 and 21.7% for grade 3, with corresponding sensitivities of 83% and 84%. After 72 weeks' of obeticholic vs placebo, 42% of subjects had a reduced steatosis grade (mean reduction in PDFF from baseline of 7.4%±8.7%), 49% had no change in steatosis grade (mean increase in PDFF from baseline of 0.3%±6.3%), and 9% had an increased steatosis grade (mean increase in PDFF from baseline of 7.7%±6.0%). PDFF change identified subjects with reduced steatosis grade with an AUROC of 0.81 (95% CI, 0.71–0.91) and increased steatosis grade with an AUROC of 0.81 (95% CI, 0.63–0.99). A PDFF reduction of 5.15% identified subjects with reduced steatosis grade with 90% specificity and 58% sensitivity, whereas a PDFF increase of 5.6% identified those with increased steatosis grade with 90% specificity and 57% sensitivity. Conclusions Based on data from a phase 2 randomized controlled trial of adults with NASH, PDFF estimated by MRI scanners of different field strength and at different sites, accurately classifies grades and changes in hepatic steatosis when histologic analysis of biopsies is used as a reference

Clinically Actionable Hypercholesterolemia and Hypertriglyceridemia in Children with Nonalcoholic Fatty Liver Disease

OBJECTIVE: To determine the percentage of children with nonalcoholic fatty liver disease (NAFLD) in whom intervention for low-density lipoprotein cholesterol or triglycerides was indicated based on National Heart, Lung, and Blood Institute guidelines. STUDY DESIGN: This multicenter, longitudinal cohort study included children with NAFLD enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Nonalcoholic Steatohepatitis Clinical Research Network. Fasting lipid profiles were obtained at diagnosis. Standardized dietary recommendations were provided. After 1 year, lipid profiles were repeated and interpreted according to National Heart, Lung, and Blood Institute Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction. Main outcomes were meeting criteria for clinically actionable dyslipidemia at baseline, and either achieving lipid goal at follow-up or meeting criteria for ongoing intervention. RESULTS: There were 585 participants, with a mean age of 12.8 years. The prevalence of children warranting intervention for low-density lipoprotein cholesterol at baseline was 14%. After 1 year of recommended dietary changes, 51% achieved goal low-density lipoprotein cholesterol, 27% qualified for enhanced dietary and lifestyle modifications, and 22% met criteria for pharmacologic intervention. Elevated triglycerides were more prevalent, with 51% meeting criteria for intervention. At 1 year, 25% achieved goal triglycerides with diet and lifestyle changes, 38% met criteria for advanced dietary modifications, and 37% qualified for antihyperlipidemic medications. CONCLUSIONS: More than one-half of children with NAFLD met intervention thresholds for dyslipidemia. Based on the burden of clinically relevant dyslipidemia, lipid screening in children with NAFLD is warranted. Clinicians caring for children with NAFLD should be familiar with lipid management

Haptoglobin 2 Allele is Associated With Histologic Response to Vitamin E in Subjects With Nonalcoholic Steatohepatitis

Background: Haptoglobin (Hp) genotype has been linked to oxidative stress and response to vitamin E (VitE) in patients with dyslipidemia. Its effect on histological response to VitE in nonalcoholic steatohepatitis (NASH) is unknown. Goals: Our objective was to determine if Hp genotype associates with response to VitE in patients with NASH. Study: A post hoc analysis of 228 patients receiving VitE or placebo in two clinical trials was performed. Regression analysis was used to assess the effect of VitE versus placebo, by Hp genotype (1–1, 2–1, or 2–2), on histologic features and laboratory markers of liver disease, comparing baseline to end of treatment values. An interaction term was included in the regression models to assess differential treatment effect across Hp genotype. Results: Hp 2–2 patients treated with VitE versus placebo showed significant histologic improvement (51% versus 20%, OR=4·2, p=0·006), resolution of steatohepatitis (44% versus 12%, OR=6.2, p=0·009), decrease in NAFLD Activity Score (NAS) (−2·2 versus −0·6, p=0·001), and decrease in liver enzymes alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and γ-glutamyl transpeptidase. Hp 2–1 patients on VitE versus placebo showed improved resolution of steatohepatitis, NAS and liver enzymes. Hp 1–1 patients showed no significant improvement in histology or liver enzymes. VitE had no effect on fibrosis stage in any group. Regression analysis showed incremental benefit of having Hp 2–2 or 2–1 versus 1–1 for all liver enzymes. Conclusion: Hp 2 allele is associated with greater histological and biological improvement in NASH with VitE treatment compared to the Hp 1 allele

Unity in defence: honeybee workers exhibit conserved molecular responses to diverse pathogens

This is the final version of the article. Available from the publisher via the DOI in this record.Background: Organisms typically face infection by diverse pathogens, and hosts are thought to have developed specific responses to each type of pathogen they encounter. The advent of transcriptomics now makes it possible to test this hypothesis and compare host gene expression responses to multiple pathogens at a genome-wide scale. Here, we performed a meta-analysis of multiple published and new transcriptomes using a newly developed bioinformatics approach that filters genes based on their expression profile across datasets. Thereby, we identified common and unique molecular responses of a model host species, the honey bee (Apis mellifera), to its major pathogens and parasites: the Microsporidia Nosema apis and Nosema ceranae, RNA viruses, and the ectoparasitic mite Varroa destructor, which transmits viruses. Results: We identified a common suite of genes and conserved molecular pathways that respond to all investigated pathogens, a result that suggests a commonality in response mechanisms to diverse pathogens. We found that genes differentially expressed after infection exhibit a higher evolutionary rate than non-differentially expressed genes. Using our new bioinformatics approach, we unveiled additional pathogen-specific responses of honey bees; we found that apoptosis appeared to be an important response following microsporidian infection, while genes from the immune signalling pathways, Toll and Imd, were differentially expressed after Varroa/virus infection. Finally, we applied our bioinformatics approach and generated a gene co-expression network to identify highly connected (hub) genes that may represent important mediators and regulators of anti-pathogen responses. Conclusions: Our meta-analysis generated a comprehensive overview of the host metabolic and other biological processes that mediate interactions between insects and their pathogens. We identified key host genes and pathways that respond to phylogenetically diverse pathogens, representing an important source for future functional studies as well as offering new routes to identify or generate pathogen resilient honey bee stocks. The statistical and bioinformatics approaches that were developed for this study are broadly applicable to synthesize information across transcriptomic datasets. These approaches will likely have utility in addressing a variety of biological questions.This article is a joint effort of the working group TRANSBEE and an outcome of two workshops kindly supported by sDiv, the Synthesis Centre for Biodiversity Sciences within the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig, funded by the German Science Foundation (FZT 118).
