Clinical application of photoacoustic imaging for cervical precursor lesion detection.

Article Synopsis
- - Early diagnosis of cervical precursor lesions is crucial for preventing cervical cancer, and while colposcopy is commonly used, it has low accuracy and consistency, prompting the exploration of alternative diagnostic techniques.
- - This study investigated the use of photoacoustic (PA) imaging to enhance early detection of severe cervical lesions by examining 21 surgical patients and 114 outpatients at a colposcopy clinic, assessing PA findings against pathological results.
- - Results showed that PA imaging effectively identified dense angiogenesis in severe lesions, leading to a high detection rate (positive predictive value of 84.5% and negative predictive value of 82.1%), suggesting it could improve the accuracy of cervical cancer diagnostics.
Background: The prevalence and risk factors of postpartum posttraumatic stress disorder reported by population-based studies have significantly varied and the data are all collected from regional populations in Mainland China.
Aims: To utilize published data to estimate the overall prevalence of postpartum posttraumatic stress disorder and its determinants in Mainland China.
Methods: Comprehensively electronic searches were performed across six English databases and three Chinese databases.
μ-Oxo-Hypervalent-Iodine-Catalyzed Oxidative C-H Amination for Synthesis of Benzolactam Derivatives.

Benzolactams have unique biological activity and high utility in the synthesis of valuable compounds with direct applicability to oxindole alkaloids and antibacterial agents. Despite recent advances in organic chemistry and the growing number of reported methods for synthesizing benzolactams, their preparation still requires a multistep process. C-H amination reactions can convert aromatic C(sp)-H bonds directly to C(sp)-N bonds, and this direct approach to C-N bond formation offers effective access to benzolactams.
