title: raw data-Eimeria tenella can promote secondary EPEC infection in hosts by increasing the chicken TGF-β1.zip

description: Previous studies demonstrated that <i>Eimeria tenella</i> induced severe secondary bacterial infections in chicks, exacerbating disease progression and causing greater economic losses. It was well known that transforming growth factor-β1 (TGF-β1) influenced cytoskeletal architecture, serving as a key factor for bacterial adhesion to host cells. In this study, both a primary chicken embryonic cecal epithelial cell (PCEC) infection model and an in vivo chicken infection model were established. The role of TGF-β1 in <i>E. tenella</i>-induced secondary infection by enteropathogenic <i>Escherichia coli</i> (EPEC) was investigated through analyses of host physiological, pathological, and transcriptional changes, as well as cellular structural alterations. Infection with <i>E. tenella</i> significantly enhanced TGF-β1 secretion by PCECs and increased EPEC adhesion. Exogenous administration of chicken TGF-β1 led to pronounced cytoskeletal remodeling in PCECs, and EPEC adhesion was dose-dependently increased following TGF-β1 treatment. Transcriptomic analysis of cecal tissue revealed significant changes in TGF-β1–associated genes, including <i>INHBA</i>, <i>LEFTY1</i>, <i>IFNG</i>, and <i>ROCK1</i>, indicating host regulatory responses at the genetic level to <i>E. tenella</i> infection that may contribute to elevated TGF-β1 secretion. These findings suggested that <i>E. tenella</i> promoted pathogenic adhesion via TGF-β1–mediated cytoskeletal modifications in host cells. The study provided a mechanistic basis for the role of TGF-β1 in facilitating secondary pathogen infections during <i>E. tenella</i> infection and identified potential molecular targets for the development of anti-secondary infection therapeutics.

title: Global Assessment of Agrivoltaics Systems Potential for Major Cropping Systems

description: The dataset and codes support the research presented in the manuscript "Global Assessment of Agrivoltaic Systems Potential for Major Cropping Systems" (Karimzadeh et al., 2025). It includes MATLAB scripts and processed data for evaluating the Daily Light Integral (DLI) and precipitation during the crop calendars of wheat, maize, rice, and soybean at the global scale.

The analysis is based on daily solar radiation and precipitation data from 2014 to 2023. Scripts (wheat_zenodo.m, maize_zenodo.m, rice_zenodo.m, and soybean_zenodo.m) are provided to reproduce the DLI and precipitation datasets. The all4crops_final.m script loads the combined results and generates the figures used in the publication.

Contents:





MATLAB scripts for each crop




Pre-processed DLI and precipitation data (stored in DLI_prec_results)




Main script for figure reproduction



Recommended Use:Run all4crops_final.m after ensuring that the DLI_prec_results folder is accessible in your MATLAB path.

description: This dataset contains georeferenced information on large and most smaller dams and reservoirs in Switzerland, including dam names, coordinates, years of construction, and maximum reservoir volumes. It was created as part of a bachelor's thesis at ETH Zurich in the Chair of Hydrology and Water Resources Management. Created to support spatial analyses of river fragmentation and hydrological regulation, the dataset merges official sources with new information on dam locations and provides a basis for further hydrological and ecological studies.

title: IODP Expedition 403 Per-fluorocarbon tracers (PFT)

description: Perfluorocarbon tracers (PFT) can be used to quantify the amount of core contamination due to drilling fluid. PFT is continuously pumped into the stream of drilling fluid to maintain a consistent concentration. Core subsamples are then measured in triplicate using µECD gas chromatography. Measured levels of PFT of the core outer surface, the outer core surface after undergoing a decontamination procedure, and the inner core are then compared to determine the degree of contamination.
