Deep imaging of LepR stromal cells in optically cleared murine bone hemisections.
Bone Res
January 2025
National Institute of Biological Sciences, Beijing (NIBS), 102206, Beijing, China.
Tissue clearing combined with high-resolution confocal imaging is a cutting-edge approach for dissecting the three-dimensional (3D) architecture of tissues and deciphering cellular spatial interactions under physiological and pathological conditions. Deciphering the spatial interaction of leptin receptor-expressing (LepR) stromal cells with other compartments in the bone marrow is crucial for a deeper understanding of the stem cell niche and the skeletal tissue. In this study, we introduce an optimized protocol for the 3D analysis of skeletal tissues, enabling the visualization of hematopoietic and stromal cells, especially LepR stromal cells, within optically cleared bone hemisections.

Department of Radiology, Changhai Hospital, Naval Medical University, Changhai Road 168, Shanghai 200433, China. Electronic address:
Background: Lysosomes, as an indispensable subcellular organelle have numerous physiological functions closely associated with HS and viscosity, and accurate assessment of HS/viscosity fluctuations in lysosomes is essential for gaining a comprehensive understanding of lysosome-related physiological activities and pathological processes. The previous single-response fluorescent probes for either HS or viscosity alone have the potential to generate "false positive" signals in a complex biological environment. In contrast, dual-locked probes can simultaneously respond to multiple targets simultaneously, which could effectively eliminate this defect.

Background: Amplified imaging of microRNA (miRNA) in cancer cells is essential for understanding of the underlying pathological process. Synthetic catalytic DNA circuits represent pivotal tools for miRNA imaging. However, most existing catalytic DNA circuits can not achieve the reactant recycling operation in cells and in vivo.

Environ Res
January 2025
School of Remote Sensing & Geomatics Engineering, Nanjing University of Information Science & Technology, No.219, Ningliu Road, Nanjing, 210044, Jiangsu, China.
Heat extremes become increasingly frequent and severe, posing adverse risks to public health and environment. Previous research on extreme heat mostly used meteorological observations or reanalysis data, which cannot well capture detailed spatial patterns. This study developed a seamless air temperature (T) dataset from remote sensing data to characterize the spatio-temporal variations of heat extremes in the Yangtze River Delta (YRD) from 2001 to 2023.

Department of Epidemiology, Faculty of Medicine, Prince of Songkla University, Hat Yai, Thailand. Electronic address:
The growing issue of drug resistance, particularly multidrug-resistant TB (MDR-TB), has exacerbated this problem. The rise of drug resistance TB is a severe global health concern. In Thailand, a persistent community outbreak of primary MDR-TB has been confirmed in the Tha Maka district of Kanchanaburi province, with an increasing prevalence of MDR-TB among newly diagnosed pulmonary tuberculosis cases.
