[Effects of corn straw biochar on process, nutrient content, and CO emissions of corn straw decomposition].

Article Synopsis
- Biochar, a carbon-rich and alkaline substance with a porous structure, was studied for its effects on corn straw composting through a 90-day experiment with varying biochar concentrations (0%, 5%, 10%, and 20%).
- The addition of biochar notably accelerated temperature increases and facilitated straw decomposition, enhancing microbial activity by increasing pH and electrical conductivity in the composting environment.
- While nitrogen levels remained unchanged, biochar significantly boosted phosphorus and potassium content in the compost, and improved carbon dioxide emissions during the composting process, indicating better organic matter breakdown by microbes.

Objective: To explore the working mechanism and age-related change of the conflict processing system of the frontal cortex.
Methods: Fifteen normal elderly people and 15 youth were performed a modified Eriksen flanker paradigm, while event-related potential (ERPs), which include 32 systerm electroencephalography, reaction time and correct rate were recorded.
Results: The elderly group showed a distinct effect of reaction time and effect of conflict in the respond level compared with the youth group.
The activities of transcription factors (TFs) require interactions with specific DNA sequences and other regulatory proteins. To detect such interactions in Arabidopsis, we developed a high-throughput screening system with a Gateway-compatible Gal4-AD-TF library of 1589 Arabidopsis TFs, which can be easily screened by mating-based yeast-one-hybrid (Y1H) and yeast-two-hybrid (Y2H) methods. The efficiency of the system was validated by examining two well-characterized TF-DNA and TF-protein interactions: the CHE-CCA1 promoter interaction by Y1H and NPR1-TGAs interactions by Y2H.

Methods: The participants underwent a comprehensive in-person evaluation including detailed neuropsychological testing, Hospital Anxiety and Depression Scale and special questionnaires for movement and sleep disorders.
Results: The overall prevalence of cognitive impairment, extrapyramidal diseases was 32.
