title: Files related to a Picture-Based Language Production Experiment on Subjective Motion in Mandarin

description: The dataset contains anonymized responses from a picture-based language production experiment designed to investigate subjective motion in Mandarin. One hundred native speakers of Mandarin produced spatial descriptions of picture stimuli representing different entity types and perspectives. The data provide empirical evidence for examining construal operations, aspectual choices, and experiential motivations in language production.

title: The genus Streblocera Westwood (Hymenoptera: Braconidae: Euphorinae) from India, with descriptions of 9 new species

description: This dataset contains the digitized treatments in Plazi based on the original journal article Shamim, Mohammad, O, Published (2013): The genus Streblocera Westwood (Hymenoptera: Braconidae: Euphorinae) from India, with descriptions of 9 new species. Turkish Journal of Zoology 37 (4): 385-405, DOI: 10.3906/zoo-1207-36, URL: http://dx.doi.org/10.3906/zoo-1207-36Abstract: Nine new species of the subgenus Eutanycerus of the genus Streblocera Westwood are described. These are: Streblocera (Eutanycerus) achterbergi sp. nov., S. (E.) aurrayyus sp. nov., S. (E.) etawahiana sp. nov., S. (E.) hayati sp. nov., S. (E.) kanpurensis sp. nov., S. (E.) levipleuron sp. nov., S. (E.) sharifi sp. nov., S. (E.) shawi sp. nov., and S. (E.) shujauddini sp. nov. This genus was previously recorded from India based on a species identified as S. macroscapa (Ruthe). However, the available specimens in the Department of Zoology at Aligarh Muslim University do not permit a definite confirmation of the species. A key to the Indian species of Streblocera (Eutanycerus) is given.

title: <b>In Vitro Fermentation Characteristics of Fructo</b><b>-</b><b>oligosaccharides and Their Effects on Reproductive Performance and Associated Metabolic Syndromes in Peripartum Sows</b>

description: Sows face peripartum metabolic syndrome (PPMS), characterized by inflammation, oxidative stress, and insulin resistance, driven by gut microbiota dysbiosis. This study aimed to evaluate fructo-oligosaccharides (FOS) as a nutritional intervention to modulate gut microbiota and alleviate PPMS, improving reproductive efficiency. <b>Methods</b>: In vitro fermentation assessed FOS fermentability (gas kinetics, short-chain fatty acids [SCFAs]), while a randomized trial (n = 60 sows) evaluated 10 g/day FOS from gestational day (GD) 90 to farrowing. Key outcomes included reproductive performance, PPMS biomarkers (inflammatory/oxidative stress markers), and gut microbiota via 16S rRNA sequencing. Results: In vitro, FOS promoted sustained butyrate production (14.3±1.2 mM) and a biphasic gas profile aligning with distal gut transit. In sows, FOS reduced lactational backfat loss by 23% (P &lt; 0.05) and shortened weaning-to-estrus interval by 1.8 days (P &lt; 0.05). Fecal lipopolysaccharide (LPS,↓48% at GD109, P &lt; 0.001) and plasma reactive oxygen species (ROS,↓41% at lactation day 3, P &lt; 0.01) were attenuated, with increased immunoglobulin G (IgG,↑33% at GD109, P &lt; 0.001). Microbiota analysis showed enriched butyrate producers (Roseburia, Treponema) and a lower Firmicutes/Bacteroidota ratio (1.9–2.7-fold, P &lt; 0.01), preserving community structure. <b>Conclusions:</b> Late-gestation FOS supplementation mitigates PPMS by enhancing gut-derived SCFAs, reducing inflammation/oxidative stress, and improving reproductive cyclicity, offering a precision nutrition strategy for sustainable swine production.
