Silicosis, a severe occupational chronic pneumonia, results from prolonged exposure to high concentrations of crystalline SiO in occupational environments. The inhaled SiO particles recruit and activate alveolar macrophages (AMs), leading to hypoxia within the AMs that causes a series of biological changes in AMs. These changes include morphological alterations, inflammatory responses, cell death, and secretion of fibrosis-associated cytokines, inducing silicosis fibrosis.

Background: Lung cancer, particularly non-small cell lung cancer (NSCLC), accounts for about 85% of all lung cancer cases and remains a major global health challenge. Traditional diagnostic methods, such as chest X-rays and low-dose CT scans, have limitations, including high false-positive rates, radiation risks, and the invasiveness of tissue biopsies. This study aims to develop a non-invasive liquid biopsy approach for early NSCLC diagnosis.

Terahertz metamaterials exhibit significant potential for applications in electromagnetic ultrafast response, wavefront modulation, and electromagnetic wave transmission. However, the transmission properties of these metamaterials remain fixed once the structure and materials of the device are established, which severely limits their modulation capability and operational range. In this study, a terahertz wave device that enables absorption/reflection bi-directional modulation was designed based on the property that the conductivity of GaAs can be modulated by pumping light.

Objectives: The use of risk analytics indices alongside clinical factors has potential to assist clinicians in identifying children at high risk for extubation failure (EF). We investigated the association of two physiologic risk analytics indices with EF in children receiving mechanical ventilation (MV) after cardiac surgery: the probability of inadequate oxygen delivery (ID o2 ) and inadequate ventilation of carbon dioxide index (IV co2 ). A secondary aim was to evaluate clinical factors associated with EF.

Inhibition of autophagy has been considered as a promising strategy for tumor therapy, discovery of small-molecule autophagy inhibitors suitable for clinical use would be of great significance. Since cysteine protease ATG4B plays a key role in the autophagy machinery by processing pro-LC3 and lipidated LC3 to drive the autophagy progress, inhibition of ATG4B may serve as a potential therapeutic strategy. We previously found that copper ions instead of other ions efficiently inhibited ATG4B activity, which was more potent than other ATG4B inhibitors reported.

Silicosis, a chronic lung disease, results from prolonged inhalation of silica dust (SiO) in occupational environments, and its pathogenesis remains incompletely elucidated. Studies have shown that alveolar macrophages (AMs) play a pivotal role in its development. These AMs phagocytose the inhaled SiO, which leads to morphological, structural, and functional abnormalities that result in lung fibrosis.

Probiotics emerges as a promising option for ulcerative colitis (UC) treatment, but its application remains challenging due to insufficient colon-targeted delivery efficiency and survival against the inflammation-associated intestinal oxidative stress. To address these issues, here we report a supramolecular liposome-microgel complex (SLMC) incorporated with Bacillus subtilis spores (BSSs) and dexamethasone (DEX) for orally-deliverable probiotic UC therapy. Specifically, BSSs and cholesterols were conjugated with gelatin via diselenide ligation to prepare microgels, followed by supramolecular complexation with UC-targeted DEX-loaded liposome via microfluidic engineering.

Lung cancer screening with computed tomography (CT) scans can effectively improve the survival rate through the early detection of lung cancer, which typically identified in the form of pulmonary nodules. Multiple sequential CT images are helpful to determine nodule malignancy and play a significant role to detect lung cancers. It is crucial to develop effective lung cancer classification algorithms to achieve accurate results from multiple images without nodule location annotations, which can free radiologists from the burden of labeling nodule locations before predicting malignancy.

To date, cyclodextrins (CDs) and their derivatives are recognized as highly effective chiral selectors in electrophoresis for enantiomer separation due to their numerous advantages. In this study, three amino-β-CD derivatives, including NH-β-CD-5 (Mono-(6-(tetraethylenepentamine)-6-deoxy)-beta-Cyclodextrin), NH-β-CD-3 (mono-(6-(diethylenetriamine)-6-deoxy)-β-Cyclodextrin), and NH-β-CD-1 (6-Monodeoxy-6-monoamino-beta-cyclodextrine) with varying amino substituent chain lengths were employed as chiral selectors in capillary electrophoresis (CE) to examine their chiral selectivity in the separation of five dansylated amino acid enantiomers, namely Dns-DL-Val, Dns-DL-Leu, Dns-DL-Thr, Dns-DL-Phe, and Dns-DL-Ser, as the chain length of the substituent group significantly impacts separation performance. Among the three amino-β-CD derivatives, NH-β-CD-5 exhibited superior performance by separating four dansylated amino acid enantiomers, whereas NH-β-CD-3 and NH-β-CD-1 separated only two and one enantiomers, respectively.

Most patients with colorectal cancer do not achieve durable clinical benefits from immunotherapy, underscoring the existence of alternative immunosuppressive mechanisms. Here we found that activation of the lactate receptor HCAR1 signaling pathway induced the expression of chemokines CCL2 and CCL7 in colorectal tumor cells, leading to the recruitment of immunosuppressive CCR2 polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) to the tumor microenvironment. Ablation of Hcar1 in mice with colorectal tumors significantly decreased the abundance of tumor-infiltrating CCR2 PMN-MDSCs, enhanced the activation of CD8 T cells and, consequently, reduced tumor burden.

Tuberculosis (TB) is notoriously difficult to treat, likely due to the complex host-pathogen interactions driven by pathogen heterogeneity. An understudied area of TB pathogenesis is host responses to bacteria (Mtb) that are limited in zinc ions. This distinct population resides in necrotic granulomas and sputum and could be the key player in tuberculosis pathogenicity.
