Background: Vertebral Hounsfield unit (HU) were regarded as a new way to predict fragility fracture. However, HU values were measured in a single plane, which is not accurate for the entire vertebral body. This study aimed to create a new CT-based metric for assessing bone mineral density, three-dimensional Hounsfield unit value (3D-HU), and to evaluate its effect in independently predicting new vertebral fracture (NVF) after percutaneous vertebral augmentation (PVA) in postmenopausal women.

In this paper, we introduce a novel method of Filtering and Serializing Spatial Information to tackle uncalibrated photometric stereo tasks, termed FSSI-PS. Photometric stereo aims to recover surface normals from images with varying lighting and is crucial for tasks like 3D reconstruction and defect detection. Current methods in complex surface reconstruction are costly and inaccurate due to redundant feature representations from GCN or Transformer modules, caused by the weak global information extraction capability of GCNs or the large computational cost of Transformers.

Stimuli-responsive camouflage systems with printable architectures and long-term stability are of paramount importance in advanced military applications. In such adaptive camouflage devices, the stimulus-responsive layer that modulates chromatic properties plays a pivotal role. A critical challenge in electrothermal-actuated camouflage systems lies in mitigating the aggregation and enhancing the temporal stability of solution-processed silver nanowires (AgNWs) employed as the active stimulus layer.

In recent years, the relationship between the immunosuppressive niche of the bone marrow and therapy resistance in acute myeloid leukemia (AML) has become a research focus. The abnormal number and function of immunosuppressive cells, including regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs), along with the dysfunction and exhaustion of immunological effector cells, including cytotoxic T lymphocytes (CTLs), dendritic cells (DCs) and natural killer cells (NKs), can induce immune escape of leukemia cells and are closely linked to therapy resistance in leukemia. This article reviews the research progress on the relationship between immune cells in the marrow microenvironment and chemoresistance in AML, aiming to provide new ideas for the immunotherapy of AML.

There are few in vitro models available to study microglial physiology in a homeostatic context. Recent approaches include the human induced pluripotent stem cell model, but these can be challenging for large-scale assays and may lead to batch variability. To advance our understanding of microglial biology while enabling scalability for high-throughput assays, we developed an inducible immortalized murine microglial cell line using a tetracycline expression system.

A PhPO-modulated β-selective Kdo glycosidation approach is developed for the stereoselective synthesis of β-Kdo glycosides. With the readily available per--acetylated Kdo ynenoate as the donor, the glycosylation with a series of alcohols in the presence of PhPAuOTf and PhPO in toluene at low temperatures afforded the desired Kdo glycosides with good to excellent β-selectivities. Furthermore, the PhPO-modulated approach was effectively applied to the synthesis of β-(2→4)- and β-(2→8)-linked Kdo-Kdo disaccharides for further biological studies.
