Isovolumic relaxation intraventricular pressure difference predicts elevated left ventricular end-diastolic pressure in patients with coronary artery disease.

Current guideline for evaluating diastolic function requires multiple parameters to identify patients with elevated left ventricular end-diastolic pressure (LVEDP). However, the intermediate result still exists and may cause LVEDP undetermined. Previous studies have shown intraventricular pressure difference (IVPDs) are required for normal LV filling, but the relationship between IVPDs and LVEDP is unknown.

Biventricular function after Ebstein anomaly repair from a single-center echocardiography study.

Objective: We aimed to examine biventricular remodeling and function after Ebstein anomaly (EbA) surgical correction using echocardiographic techniques, particularly, the relations between the biventricular changes and the EbA types.

Methods: From April 2015 to August 2022, 110 patients with EbA were included in this retrospective study based on the Carpentier classification. Echocardiography assessments during the preoperative, early, and mid-term postoperative periods were performed.

Identifying cadmium and lead co-accumulation from living rice blade spectrum.

Neither cadmium (Cd) nor lead (Pb) is necessary for crop growth, but they both can accumulate in soil and crop tissues, resulting in land degradation and crop reduction. Few researchers have explored how to detect Cd-Pb co-accumulation in leaves using proximal sensing techniques, especially by low-cost, easy-to-use leaf clips that capture hyperspectral reflections at suitable foliar positions. In this study, a hyperspectral imager was employed to collect images of the rice canopy from a designed greenhouse experiment that included 16 pretreatments of Cd-Pb co-accumulation, followed by spectral extractions from 3 foliar positions: the blade root, the middle of the leaf, and the leaf apex.

Development of the Social Media Engagement Scale for Adolescents.

This study aimed to develop the Social Media Engagement Scale for Adolescents (SMES-A), and evaluate its reliability and validity. The initial items were collected via open-ended questions, a literature review, and suggestions from psychological experts. A total valid sample of 2519 adolescents participated in this study.

Vegetation net primary productivity and its response to climate change during 2001-2008 in the Tibetan Plateau.

Alpine ecosystems are highly sensitive to global climate changes. The Tibetan Plateau is one of the areas that are most sensitive to global climate change. Increases in temperature and changes in precipitation can impact the plateau's ecosystem productivity.

A primary pericardial undifferentiated sarcoma invading the right atrium and superior vena cava.

Primary undifferentiated cardiac sarcomas are rare. The literature demonstrated that 81% of primary cardiac undifferentiated sarcomas arose in the left atrium. We reported herein a case of 56-year-old male farmer with a primary pericardial undifferentiated sarcoma, which was revealed only on echocardiography but not computed tomography.
