Drawing from job-demands resources theory and conservation of resources theory, this study examines the effect of performance pressure on interpersonal citizenship behavior through exhaustion. We also explore the extent to which receiving help mitigates the exhaustion caused by performance pressure. In a critical incident design of employees from various industries ( = 268), performance pressure was positively associated with exhaustion. Subsequently, employee exhaustion decreased the tendency to perform acts of interpersonal citizenship. The relationship between performance pressure and exhaustion was weakened among employees who had received help from their colleagues. Thus, these results, supported by moderated mediation analyses, suggest that receiving help can mitigate the deleterious effects of performance pressure on interpersonal citizenship behavior through exhaustion. Implications for research and practice are discussed.

Purpose: Atrial fibrillation (AF) is the most common chronic cardiac arrhythmia that increases the risk of stroke, primarily due to thrombus formation in the left atrial appendage (LAA). Left atrial appendage occlusion (LAAO) devices offer an alternative to oral anticoagulation for stroke prevention. However, the complex and variable anatomy of the LAA presents significant challenges to device design and deployment.

Purpose: To quantify the separation between maternal blood cell-free (cf)DNA markers in preeclampsia and unaffected pregnancies and compare with existing markers. This approach has not been used in previous studies.
Methods: Comprehensive systematic literature search of PubMed to identify studies measuring total cfDNA, fetal cf(f)DNA or the fetal fraction (FF) in pregnant women.

Partial stenosis of the renal artery causes renovascular hypertension (RVH) and is accompanied by chronic renal ischemia, resulting in irreversible kidney damage. Revascularization constitutes the most efficient therapy for normalizing blood pressure (BP) and has significant benefits for renal function; however, the tissue damage caused by chronic hypoxia is not fully reversed. Mesenchymal stem cells (MSCs) have produced discrete results in minimizing RVH and renal tissue and functional improvements since the obstruction persists.

The Laser Interferometer Space Antenna (LISA) mission is designed to detect space gravitational wave sources in the millihertz band. A critical factor in the success of this mission is the residual acceleration noise metric of the internal test mass (TM) within the ultra-precise inertial sensors. Existing studies indicate that the coupling effects of residual gas and temperature gradient fluctuations significantly influence this metric, primarily manifesting as the radiometer effect and the outgassing effect.

Background: Conventional treatments for cardiometabolic diseases face limitations related to cost, efficacy, and side effects. Hibiscus sabdariffa (HS) is a common food product and a potential alternative. However, previous studies have shown inconsistent results and lacked assessments of result certainty, intervention safety, and subgroup analysis credibility.
