Background: Reliable pre-surgical prediction of spreading through air spaces (STAS) in primary lung cancer is essential for precision treatment and surgical decision-making. We aimed to develop and validate a dual-delta deep-learning and radiomics model based on pretreatment computed tomography (CT) image series to predict the STAS in patients with lung cancer.

Method: Six hundred seventy-four patients with pre-surgery CT follow-up scans (with a minimum interval of two weeks) and primary lung cancer diagnosed by surgery were retrospectively recruited from three Chinese hospitals.

Non-linear modifications enhance prediction of pathological response to pre-operative PD-1 blockade in lung cancer: A longitudinal hybrid radiological model.

Major pathologic remission (MPR, residual tumor <10%) is a promising clinical endpoint for prognosis analysis in patients with lung cancer receiving pre-operative PD-1 blockade therapy. Most of the current biomarkers for predicting MPR such as PD-L1 and tumor mutation burden (TMB) need to be obtained invasively. They cannot overcome the spatiotemporal heterogeneity or provide dynamic monitoring solutions.

The sensitive and rapid detection of Ochratoxin A in foods is particularly urgent for ensuring human security due to its larger toxicity to the body. Herein, a novel competitive fluorescence colorimetric dual-mode immunosensor for detecting Ochratoxin A based on AuAg NCs-SPCN nanocomposite was designed and constructed. The synergistic effect of SPCN and AuAg NCs dramatically improved the nanozyme activity.

Co-delivery of minoxidil and tocopherol acetate ethosomes to reshape the hair Follicular Microenvironment and promote hair regeneration in androgenetic alopecia.

The most prevalent kind of hair loss is androgenic alopecia (AGA), which is characterized by hair follicle miniaturization and microenvironment dysfunction. Although topical Minoxidil (MXD) was considered to be a safe and effective treatment for AGA, excess reactive oxygen species (ROS) and lower sulfotransferase activity in the hair follicular microenvironment led to an unsatisfactory treatment of AGA. Here, we developed the ethosome (MTE) load of minoxidil and tocopherol acetate to improve the therapeutic effect of MXD on androgenic alopecia.
