Purpose: To retrospectively investigate clinical and computed tomographic (CT) features of transient part-solid nodules (PSNs) initially detected at screening thin-section CT for lung cancer and to determine predictive factors that may differentiate transient PSNs from persistent PSNs. Materials and Methods: This study was approved by the institutional review board. From January 2006 to August 2008, 93 individuals with 126 PSNs were identified from among 16 777 individuals who underwent chest CT. Clinical features and CT characteristics of PSNs were reviewed, and clinical and thin-section CT features were compared between transient and persistent PSNs. To identify predictive factors of transient PSNs and evaluate predictive performance, logistic regression analysis and C statistic analysis were performed. Results: Eighty-eight (69.8%) of 126 PSNs were transient. Between transient and persistent PSNs, there were significant differences (P<.05) in patient age, patient sex, risk of lung cancer, presence of eosinophilia, mode of detection, lesion size, lesion multiplicity, size of solid portion, and lesion border. Multivariate analysis revealed that young patient age, detection of the lesion at follow-up, blood eosinophilia, lesion multiplicity, large solid portion, and ill-defined border were significant (P<.05) independent predictors of transient PSNs. The performance in the discrimination of transient PSNs from persistent PSNs of the logistic regression model that incorporated both clinical and thin-section CT features was significantly higher than the performance of the models that incorporated clinical features or thin-section CT features alone. Conclusion: A substantial proportion of PSNs detected at screening CT were transient. Transient PSNs could be predicted with high accuracy by using the features of young patient age, detection of the PSN at follow-up, blood eosinophilia, lesion multiplicity, large solid portion, and ill-defined lesion border.

Summary: This paper proposes a remote monitoring technology to observe a patient's condition in real time, addressing the inconvenience of daily observation required in free flap surgery. The camera system captures images of the surgical site every 2 seconds and transmits them to the attending physician or nurse via Wi-Fi. Results show that high-quality images are obtained without any storage errors during the shooting process.

Rational design of double perovskite La2Ni0.5Co0.5MnO6 decorated polyaniline array on MoO3 nanobelts with strong heterointerface boosting oxygen evolution reaction and urea oxidation

Velusamy Maheskumar, Karunamoorthy Saravanakumar, Jagan Govindan, Chang Min Park

Summary: The design and implementation of a novel heterostructure interface of La2Ni0.5Co0.5MnO6 nanoparticles and MoO3 nanobelt array-supported amorphous polyaniline (PANI; MoO3/P) have been developed for efficient oxygen evolution reaction (OER) and urea electrooxidation reaction (UOR). The optimized La2Ni0.5Co0.5MnO6@MoO3/P (LMP-30) showed excellent electrocatalytic performance with low overpotentials of 300 mV at 10 mA cm-2 (vs RHE) for OER and 0.48 V at 50 mA cm-2 (vs Hg/HgO) for UOR, as well as enhanced stability after 12-hour testing. This improved performance is attributed to the distinctive hierarchical nanostructure, offering synergistic effects on electrical characteristics and an electrochemically active surface area. Furthermore, the LNCM nanoparticles on the MoO3/P nanobelts provide more electrocatalytic active sites, efficient charge transport capacity, improved electrical properties, and strong electronic contacts.
