This study investigates the evolutionary game dynamics of medical knowledge sharing (KS) among Chinese hospitals under government regulation, focusing on the strategic interactions between general hospitals, community health service centers, and governmental bodies. Leveraging evolutionary game theo...

Introduction China’s progress towards achieving Sustainable Development Goals for maternal health is largely attributed to a reduction in maternal mortality rates, driven by increased in-hospital delivery services utilisation. However, recent reductions in the number of obstetric hospitals have rais...

BackgroundMenopause is a significant phase in a woman’s life and is characterized by the cessation of ovarian function and a decline in endogenous ovarian hormone levels. This hormonal transition is often accompanied by debilitating symptoms, such as hot flushes, which can significantly impair quali...

A two-dimensional calibration technique is proposed to correct the spatial nonuniformity in infrared imaging systems adapting to different integration time and time-varying offset with one-time calibration. Differing from traditional calibration-based nonuniformity correction, this method calibrates...

ObjectiveTo evaluate the therapeutic efficacy of Shanling Jiangzhi Tea (SLJZ) on hyperuricemia (HUA) mice and to investigate its mechanism.MethodsA HUA mouse model was established using a combination of uric acid (UA)and potassium oxonate. Following SLJZ intervention, changes in body weight were mon...

Background/ObjectiveThe development of population-specific reference intervals (RIs) for serum vitamin B6 (B6) in Chinese pediatric populations has not been established. Current clinical practice relies on international thresholds, but diagnostic sensitivity with domestic biochemical profiles remain...

A novel high birefringence gold-coated photonic crystal fiber (PCF) polarization filter based on surface plasmon resonance is proposed. The six elliptical holes arranged in a specific mode surrounding the core are utilized to gain high birefringence, and gold is coated inside the air holes to genera...

A metal-filled photonic crystal fiber (PCF) polarization filter based on surface plasmon resonance (SPR) is proposed and designed. The structure of the cross-section of a PCF is composed of a hexagonal lattice of air holes, in which an air hole is selectively filled with metal. We realize the polari...

ABSTRACT Sternorrhyncha, a suborder of Hemiptera, comprises sap‐feeding insects with piercing‐sucking mouthparts, most of which are important agricultural and forestry pests, including aphids, psyllids, whiteflies, and scale insects. While the mitochondrial genome is a highly accessible molecular so...

Abstract Severe convective weather events, such as heavy rainfall and flooding, are serious threats to human society. However, accurate nowcasting of these events using radar remains challenging due to the complex dynamics and nonlinear physical processes involved. Moreover, existing radar echo extr...

Over the past decades, the incidence and modality of invasive fungal infections have been significantly underestimated. And the limited availability of clinically effective antifungals further underscores the need for novel therapeutic agents. In this study, a series of novel 8-hydroxyquinolin-5-yli...

IntroductionThis study aimed to develop a human acellular amniotic membrane (HAAM) scaffold suitable for corneal endothelial transplantation. The HAAM was engineered using sequential chemical treatments and physical agitation to remove cellular components while preserving the extracellular matrix st...

IntroductionNon-alcoholic fatty liver disease (MASLD) is a common liver condition with a global prevalence of approximately 25%, often associated with overweight, obesity, and abnormalities in glucose and lipid metabolism. Its histological hallmark is hepatic steatosis. Non-alcoholic steatohepatitis...

BackgroundThe African swine fever virus (ASFV) is a highly pathogenic double-stranded DNA virus that poses a significant threat to the global swine industry. Although the CD2v protein encoded by ASFV is a key factor in viral immune evasion and pathogenicity, the mechanism underlying its interaction...
