November 2024

Department of Health Technology and Informatics, The Hong Kong Polytechnic University, Kowloon, Hong Kong SAR; Research Institute for Smart Aging, The Hong Kong Polytechnic University, Kowloon, Hong Kong SAR. Electronic address:

Purpose: To present a 2-stage framework that robustly extracts and maps reliable lung ventilation surrogates based on subregional respiratory dynamics (SRDs) measured from 4-dimensional computed tomography (4DCT) images, with comprehensive consideration of spatial and temporal heterogeneity in the ventilation process over the respiratory cycle.

Methods And Materials: We retrospectively analyzed 3 subject cohorts from the Ventilation and Medical Pulmonary Image Registration Evaluation challenge containing 4DCT and reference ventilation imaging (RefVI) scans. Lung subregions were partitioned on the 4DCT end-of-exhale base phase using anatomically constrained simple linear iterative clustering, whereas sliding-preserved interphase image registrations were performed between the base and other phases.

Lung cancer is the leading factor of cancer-related death in the worldwide. Hexavalent chromium [Cr(VI)] is a potential carcinogen for inducing lung cancers. To understand new mechanism of Cr(VI)-induced tumorigenesis and cancer development, we identified that PDK1 expression levels were greatly increased in chromium-transformed cells (Cr-T) compared to the parental BEAS-2B (B2B) cells by proteomic profiling and Western blotting; PDK1 levels were also induced in lung cancer cell lines and in lung samples of mice exposed to Cr(VI).

Riboflavin kinase binds and activates inducible nitric oxide synthase to reprogram macrophage polarization.

Redox Biol

December 2024

Department of Health Management Centre & Institute of Health Management, Sichuan Provincial People's Hospital, University of Electronic Science and Technology of China, Chengdu, 610000, China. Electronic address:

Riboflavin kinase (RFK) is essential in riboflavin metabolism, converting riboflavin to flavin mononucleotide (FMN), which is further processed to flavin adenine dinucleotide (FAD). While RFK enhances macrophage phagocytosis of Listeria monocytogenes, its role in macrophage polarization is not well understood. Our study reveals that RFK deficiency impairs M(IFN-γ) and promotes M(IL-4) polarization, both in vitro and in vivo.

Assessing the intracranial metabolic score as a novel prognostic tool in primary CNS lymphoma with end of induction-chemotherapy F-FDG PET/CT and PET/MR.

Cancer Imaging

November 2024

Department of Nuclear Medicine, State Key Laboratory of Oncology in South China, Collaborative Innovation Center of Cancer Medicine, Sun Yat-Sen University Cancer Center, Guangzhou, 510060, China.

Article Synopsis
  • This study investigates the prognostic value of a new scoring system called the intracranial metabolic score (IMS) in patients with primary central nervous system lymphoma (PCNSL) who undergo end-of-therapy imaging using F-FDG PET/CT and PET/MR.
  • The IMS is based on the metabolism of normal brain structures and was shown to outperform the traditional Deauville score (DS) in predicting progression-free survival (PFS) and overall survival (OS).
  • Results from the study suggest that a higher IMS score is associated with worse patient outcomes, confirming the IMS as a valuable prognostic tool for assessing PCNSL treatment effectiveness.

Department of Laboratory Medicine, Chongqing General Hospital, School of Medicine, Chongqing University, Chongqing, 401147, People's Republic of China; College of Life Science and Laboratory Medicine, Kunming Medical University, Kunming, Yunnan, 650050, People's Republic of China. Electronic address:

Conventional point-of-care lateral flow immunoassays are characterized by an antibody-tagged probe irregular coupling that can limit sensitivity and require a long assay's time. We synthesized polyethylene glycol-modified selenium nanoparticles (PEG-SeNPs) by template method and developed a strategy to set antibody probes targeted and orderly by using PEG-SeNPs. Synthesized PEG-SeNPs with high stability could immobilize antibodies in the "stand-up" orientation, resulting in a faster detection time of less than 1 min by direct observer visualization without instruments or equipment.
