Abstract

An EMS (ethy methanesulfonate)-induced lethal etiolated (le) mutant obtained from the rice variety Zhongjian 100 was characterized by lethal etiolated phenotypes, with significantly reduced levels of chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids. Additionally, the mutant displayed a significantly decreased number of chloroplast grana, along with irregular and less-stacked grana lamellae. The le mutant showed markedly diminished root length, root surface area, and root volume compared with the wild type. It also exhibited significantly lower catalase activity and total protein content, while peroxidase activity was significantly higher. Using the map-based cloning method, we successfully mapped the LE gene to a 48-kb interval between markers RM16107 and RM16110 on rice chromosome 3. A mutation (from T to C) was identified at nucleotide position 692 bp of LOC_Os03g59640 (ChlD), resulting in a change from leucine to proline. By crossing HM133 (a pale green mutant with a single-base substitution of A for G in exon 10 of ChlD subunit) with a heterozygous line of le (LEle), we obtained two plant lines heterozygous at both the LE and HM133 loci. Among 15 transgenic plants, 3 complementation lines displayed normal leaf color with significantly higher total chlorophyll, chlorophyll a, and chlorophyll b contents. The mutation in le led to a lethal etiolated phenotype, which has not been observed in other ChlD mutants. The mutation in the AAA+ domain of ChlD disrupted the interaction of ChlDle with ChlI as demonstrated by a yeast two-hybrid assay, leading to the loss of ChlD function and hindering chlorophyll synthesis and chloroplast development. Consequently, this disruption is responsible for the lethal etiolated phenotype in the mutant.

Abstract

Recent development of college students' ideological and political education from the perspective of Chinese cultural self-confidence is studied in this paper. Educational institutions should not unilaterally strengthen the dissemination of online ideological and political education information, but should pay attention to the two-way integration of online education and offline practice. Due to the various reasons, many civilizations in the world that were once extremely brilliant in history have been lost in the long river of history. Only the Chinese civilization has been continuous and has become the only civilization in the history of world civilization that has not been interrupted. This paper gives the new ideas regarding the ideological and political education from the perspective of Chinese cultural self-confidence.

Abstract

The aim of this study was to test whether optical coherence tomographic (OCT) guidance would provide additional useful information beyond that obtained by angiography and lead to a shift in reperfusion strategy and improved clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) with early infarct artery patency. Angiography is limited in assessing the underlying pathophysiological mechanisms of the culprit lesion. EROSION III (Optical Coherence Tomography–Guided Reperfusion in ST-Segment Elevation Myocardial Infarction With Early Infarct Artery Patency) is an open-label, prospective, multicenter, randomized, controlled study approved by the ethics committees of participating centers. Patients with STEMI who had angiographic diameter stenosis ≤ 70% and TIMI (Thrombolysis In Myocardial Infarction) flow grade 3 at presentation or after antegrade blood flow restoration were recruited and randomized to either OCT guidance or angiographic guidance. The primary efficacy endpoint was the rate of stent implantation. Among 246 randomized patients, 226 (91.9%) constituted the per protocol set (112 with OCT guidance and 114 with angiographic guidance). The median diameter stenosis was 54.0% (IQR: 48.0%-61.0%) in the OCT guidance group and 53.5% (IQR: 43.8%-64.0%) in the angiographic guidance group (P = 0.57) before randomization. Stent implantation was performed in 49 of 112 patients (43.8%) in the OCT group and 67 of 114 patients (58.8%) in the angiographic group (P = 0.024), demonstrating a 15% reduction in stent implantation with OCT guidance. In patients treated with stent implantation, OCT guidance was associated with a favorable result with lower residual angiographic diameter stenosis (8.7% ± 3.7% vs 11.8% ± 4.6% in the angiographic guidance group; P < 0.001). Two patients (1 cardiac death, 1 stable angina) met the primary safety endpoint in the OCT guidance group, as did 3 patients (3 cardiac deaths) in the angiographic guidance group (1.8% vs 2.6%; P = 0.67). Reinfarction was not observed in either group. At 1 year, the rates of predefined cardiocerebrovascular events were comparable between the groups (11.6% after OCT guidance vs 9.6% after angiographic guidance; P = 0.66). In patients with STEMI with early infarct artery patency, OCT guidance compared with angiographic guidance of reperfusion was associated with less stent implantation during primary percutaneous coronary intervention. These favorable results indicate the value of OCT imaging in optimizing the reperfusion strategy of patients with STEMI.
