Network dynamics in post-stroke cognitive impairment: insights from effective connectivity analysis.
Brain Imaging Behav
January 2025
Department of Radiology, Zhongnan Hospital of Wuhan University, Wuchang, Wuhan, Hubei, 430071, China.
This study investigates post-stroke cognitive impairment (PSCI) by utilizing spectral dynamic causal modeling (spDCM) to examine changes in effective connectivity (EC) within the default mode, executive control, dorsal attention, and salience networks. Forty-one PSCI patients and 41 demographically matched healthy controls underwent 3D-T1WI and resting-state functional magnetic resonance imaging on a 3.0T MRI.

Diatom blooms are a global ecological perturbation that releases algal organic matter (AOM), significantly affecting coastal ecosystems by altering microbial community dynamics. AOM, derived from algal cell lysis, may serve as a nutrient source influencing protistan communities. However, the effects of AOM on protistan ecology, including the community structure and assembly processes, remain largely unexplored in coastal sediments.

Department of Grain Science and Industry, Kansas State University, Manhattan, KS 66506, USA. Electronic address:
Food allergens are defined by their stability during digestion, with allergenicity largely influenced by resistance to enzymatic hydrolysis. Ovalbumin (OVA), a major egg protein, is a significant contributor to food allergies, particularly in children. Our previous work demonstrated that high hydrostatic pressure (HHP) treatment reduces OVA allergenicity by disrupting conformational epitopes and altering its structure.

Large-scale plastic wastes annually inevitably induce co-pollution of microplastics (MPs) and novel brominated flame retardants (NBFRs), while gaps remain concerning their effect on terrestrial function. We investigated the impact of polylactic acid (PLA) or polyethylene (PE) MPs after aging in soil-earthworm microcosms under decabromodiphenyl ethane (DBDPE) contamination. MPs altered the food (i.

Municipal solid waste (MSW) landfills represent underexplored microbial ecosystems. Landfills contain variable amounts of antibiotic and construction and demolition (C&D) wastes, which have the potential to alter microbial metabolism due to biocidal or redox active components, and these effects are largely underexplored. To circumvent the challenge of MSW heterogeneity, we conducted a 65-day time series study on simulated MSW microcosms to assess microbiome changes using 16S rRNA sequencing in response to 1) Fe(OH)3 and 2) Na2SO4 to represent redox active components of C&D waste as well as 3) antibiotics.
