Super-resolution CT-based intratumoral and peritumoral radiomics analysis for trinary classification of PD-L1 status in lung adenocarcinoma ≥ 1 cm

<title>Abstract</title> Objectives To explore the potential of super-resolution CT-based intratumoral and peritumoral radiomics analysis for the trinary classification of PD-L1 status in lung adenocarcinoma with a diameter of ≥ 1cm, aiming to enhance the accuracy of PD-L1 status...

Cumulative body mass index burden from childhood to mid-adulthood in relation to subclinical cardiovascular outcomes: The potential mediating role of cardiovascular risk factors

The associations of long-term body mass index (BMI) exposure, including both cumulative burden and increasing trends from childhood to adulthood, with subclinical cardiovascular outcomes remain incompletely understood, especially across distinct life stages. This study aimed to e...

Energy-Transfer-Driven[2 + 2] Cycloaddition: Synthesisof Cyclobutane-Fused Tetracycles from Indenes and Maleimides

Abstract Molecular skeletons containing fused cyclobutane rings are of significant value in drug discovery as they can increase the fraction of sp3 carbons (Fsp3) and impart conformational rigidity. Herein, we report a visible-light photocatalytic strategy for the intermolecular...

Latent profile analysis of postpartum depression symptoms and its associations with weight stigma and eating behaviors among postpartum women in China

Abstract Background Postpartum depression (PPD) represents a significant maternal health challenge with diverse symptom manifestations. Traditional analytical approaches that treat postpartum women as a homogeneous group may obscure distinct symptom patterns, limiting the develop...

Spectral-habitat analysis and perfusion fingerprinting on contrast-enhanced ultrasound for characterizing tumor perfusion in breast lesions

To develop a short-time Fourier transform (STFT)-based perfusion fingerprinting method combined with spectral-habitat analysis for characterizing pixel-wise perfusion heterogeneity on contrast-enhanced ultrasound (CEUS) and to evaluate its ability to differentiate benign and mali...

Establishing the role of ZBTB20 mutations in GnRH deficiency and impaired neurogenesis in the subventricular zone: a human cohort and animal model study

Background Congenital hypogonadotropic hypogonadism (CHH) arises from defective development or dysfunction of GnRH neurons. Olfactory bulb (OB) malformations frequently accompany CHH, a condition termed Kallmann syndrome (KS). Nevertheless, approximately 50% of CHH cases remain g...
