Shape-sensing robotic-assisted bronchoscopy combined with cone-beam computed tomography-guided cryoablation for malignant lung tumors.

Introduction: For malignant lung tumor patients who are poor surgical candidates, transbronchial cryoablation is a promising alternative treatment method and is safer than percutaneous cryoablation. This case report presents the initial clinical experience of shape-sensing robotic-assisted bronchoscopy (ssRAB) combined with cone-beam computed tomography (CBCT)-guided cryoablation for malignant lung tumor patients.

Case Presentation: Transbronchial cryoablation was performed in six patients.

Deep learning for detection and diagnosis of intrathoracic lymphadenopathy from endobronchial ultrasound multimodal videos: A multi-center study.

Convex probe endobronchial ultrasound (CP-EBUS) ultrasonographic features are important for diagnosing intrathoracic lymphadenopathy. Conventional methods for CP-EBUS imaging analysis rely heavily on physician expertise. To overcome this obstacle, we propose a deep learning-aided diagnostic system (AI-CEMA) to automatically select representative images, identify lymph nodes (LNs), and differentiate benign from malignant LNs based on CP-EBUS multimodal videos.

Background: Electromagnetic navigation bronchoscopy (ENB) and shape-sensing robotic-assisted bronchoscopy (ssRAB) are the two dominant bronchoscopic technologies for the diagnosis of peripheral pulmonary nodules (PPNs). However, data directly comparing ENB and ssRAB are limited. We designed a randomized controlled trial to compare the diagnostic performance of these two technologies.

Comparative Analysis of Natural vs Artificial Mn4Ca-clusters: Structural Insights into O-O Bond Formation in Photosystem II.

The oxygen-evolving center (OEC) of photosystem II (PSII) is a unique Mn4CaO5-cluster that catalyzes the water-splitting reaction to produce electrons, protons, and dioxygen. Recently, the detailed structures of the OEC in different S-states have been revealed by X-ray free electron laser (XFEL). To facilitate understanding the structure-function relationship of the OEC, a series of artificial Mn4CaO4-clusters have been synthesized, which closely mimic the main metal-oxide core and peripheral ligands, as well as the redox properties of the OEC.

To guide intraoperative R-EBUS probe manipulation, we aimed to simulate R-EBUS images of PPLs from preoperative computed tomography (CT) data using deep learning.

Efficacy and safety of bevacizumab and platinum‑based chemotherapy as neoadjuvant regimen for stage‑IIIA non‑squamous non‑small cell lung cancer: A retrospective study.

Bevacizumab plus platinum-based chemotherapy provides modest benefits in non-squamous non-small cell lung cancer (NSCLC), while its application as a neoadjuvant regimen has yet to be validated. The present study aimed to assess the efficacy of neoadjuvant bevacizumab plus platinum-based chemotherapy in patients with stage-IIIA non-squamous NSCLC. Data from 110 patients with stage-IIIA non-squamous NSCLC with negative driver genes, who received neoadjuvant bevacizumab plus platinum-based chemotherapy (n=50) or neoadjuvant platinum-based chemotherapy alone (n=60), and tumor resection, were retrospectively reviewed in the current study.

Synthetic MnCeO-Cluster Mimicking the Oxygen-Evolving Center in Photosynthesis.

The photosynthetic oxygen-evolving center (OEC) is a unique MnCaO-cluster that catalyses water splitting into electrons, protons, and dioxygen. Precisely structural and functional mimicking of the OEC is a long-standing challenge and pressingly needed for understanding the structure-function relationship and catalytic mechanism of O-O bond formation. Herein we report two simple and robust artificial MnCeO-complexes that display a remarkable structural similarity to the OEC in regarding of the ten-atom core (five metal ions and five oxygen bridges) and the alkyl carboxylate peripheral ligands.

Effects of paternal ionizing radiation exposure on fertility and offspring's health.

Purpose: The intergenerational effects of ionizing radiation remain controversial. Extensive insights have been revealed for DNA mutations and cancer incidence in progeny, yet many of these results were obtained by immediate post-radiation mating. However, conception at short times after radiation exposure is likely to be avoided.

Mimicking the Oxygen-Evolving Center in Photosynthesis.

The oxygen-evolving center (OEC) in photosystem II (PSII) of oxygenic photosynthetic organisms is a unique heterometallic-oxide MnCaO-cluster that catalyzes water splitting into electrons, protons, and molecular oxygen through a five-state cycle (S,  = 0 ~ 4). It serves as the blueprint for the developing of the man-made water-splitting catalysts to generate solar fuel in artificial photosynthesis. Understanding the structure-function relationship of this natural catalyst is a great challenge and a long-standing issue, which is severely restricted by the lack of a precise chemical model for this heterometallic-oxide cluster.
