To explore the influence of self-efficacy on mathematics learning ability, 311 boys and girls from the same grade in a middle school were investigated. We designed an Mathematics Self-Efficacy Scale from Schwarzer General Self-Efficacy (SGSE), and analyzed the differences about all the respondents’...

Abstract Non-Technical Summary As cities like Beijing expand rapidly, green and blue spaces (GBS)—essential for ecosystem services (ESs) such as clean air, flood control, and recreation—are increasingly threatened. This 20-year study examines how urban expansion and policy interventions have shaped...

This study partitioned evapotranspiration (ET) into vegetation transpiration (T) and soil evaporation (E) across three alpine ecosystems in the Qinghai Lake Basin, China, from 2019 to 2021 using a soil–plant-atmosphere continuum (SPAC) model. The model’s effectiveness was validated by its consistenc...

The impacts of drought stress on crop yield and quality are substantial. Drought priming during the early growth stage of plants has been shown to improve tolerance to drought stress during the reproductive stage, although its effects on grain quality remain elusive. This study investigated the infl...

Potato (Solanum tuberosum L.) is the third most important food crop worldwide after wheat and rice in terms of human consumption. A critical domestication trait for potato was the decrease of toxic steroidal glycoalkaloids (SGAs) in tuber flesh. Here, we used a diploid F2 segregating population deri...

ABSTRACT The distribution and abundance of species are crucial components of their population ecology and serve as the foundation for effective conservation efforts. However, baseline data may be insufficient in areas where surveys have been inadequately conducted, complicating the implementation of...

A preliminary screening for garlic viruses in garlic plants in Hunan, China, using existing monoplex (simplex) reverse transcription-polymerase chain reaction (RT-PCR) procedures detected four viruses/virus groups. These viruses/virus groups were Onion yellow dwarf virus (OYDV), Leek yellow stripe v...

Heatstroke (HS)-induced acute lung injury (ALI) has high morbidity and mortality with no specific therapies. Ferroptosis, a form of programmed cell death driven by lipid peroxidation due to reduced Glutathione Peroxidase 4 (GPX4) activity, is closely linked to HS-induced ALI. This study investigated...

ABSTRACT Background To assess whether changes in TP53 mutations and copy number alterations (CNA) in plasma circulating tumor DNA (ctDNA) can predict treatment response and prognosis in platinum‐resistant recurrent ovarian cancer (PROC) patients. Methods Fifty‐seven PROC patients were recruited. For...

IntroductionFew studies have focused on the optimal cycles of neoadjuvant chemoimmunotherapy (NCI). This study introduced minimal residual disease (MRD) based on circulating tumor DNA (ctDNA), and investigated the association between ctDNA-MRD and NCI cycles and pathological response.Materials and m...

Hybridization, which allows for gene flow between crops, is difficult between maize and Zea perennis. In this study, we aim to initiate and study gene flow between maize and Z. perennis via a special aneuploid plant (MDT) derived from an interspecific hybrid of the two species. The chromosome consti...
