A new species of the genus Neoperla, N. donglaii sp. nov., is described from Yunnan Province of southwestern China. The new species is assigned to the N. lushana-complex of the N. (Formosita) subgenus due to the presence of paired, ventral spiny lobes of the aedeagus. The new species was compared with related species in the subgenus. Neoperla hamata Jewett, 1975 and N. idella Stark & Sivec, 2008 are newly recorded for China and N. quadrata Wu & Claassen, 1934 specifically from Yunnan Province, China. Neoperla quadrata had not been collected for 90 years.

Stability analysis of an expansive soil slope under heavy rainfall conditions with different anchor reinforcements.
Sci Rep

Department of Geotechnical Engineering, School of Civil Engineering, Tongji University, Shanghai, 200000, China.
This study investigates the vulnerability of expansive soil slopes to destabilization and damage, particularly under intense rainfall, due to their heightened sensitivity to moisture. Focusing on a project in Yunnan Province, numerical simulation software is employed to address slope stability challenges. Meanwhile, the soil mechanical parameters of this study were acquired through experimentation.

Objective: Electroacupuncture has been shown to play a neuroprotective role following ischemic stroke, but the underlying mechanism remains poorly understood. Ferroptosis has been shown to play a key role in the injury process. In the present study, we wanted to explore whether electroacupuncture could inhibit ferroptosis by promoting nuclear factor erythroid-2-related factor 2 (Nrf2) nuclear translocation.

Background: Left ventricular (LV) myocardial contraction patterns can be assessed using LV mechanical dispersion (LVMD), a parameter closely associated with electrical activation patterns. Despite its potential clinical significance, limited research has been conducted on LVMD following myocardial infarction (MI). This study aims to evaluate the predictive value of cardiac magnetic resonance (CMR)-derived LVMD for adverse clinical outcomes and to explore its correlation with myocardial scar heterogeneity.

Changes in water, energy, and food (WEF) trade patterns may reshape water circulation patterns, leading to potential water supply and demand risks. Analysis of virtual water risk transmission characteristics and driving factors from the perspective of WEF trade is highly important for alleviating the risk of water shortages and promoting the efficient use of resources. In this paper, a set of methods for quantifying risk transmission values is constructed on the basis of China's interregional input-output model, and the key paths of interregional virtual water risk transmission caused by WEF trade are identified using innovative methods.
