Background: While immunotherapy has revolutionized oncological management, its efficacy in lung cancer patients with liver metastases remains limited, potentially due to the unique immunosuppressive microenvironment of the liver. Local liver treatment has been shown to enhance the immunotherapy response, and high-intensity focused ultrasound (HIFU), a minimally invasive local treatment, has demonstrated promising results in combination with immunotherapy. However, clinical data regarding HIFU in lung cancer with liver metastases are limited.

Article Synopsis
  • Gastric cancer has a high global mortality rate (70%) and involves immune checkpoints like PD-1 and PD-L1, which are important in its progression.
  • Solamargine, derived from traditional Chinese medicine, shows potential in suppressing various cancers, but its specific impact on PD-L1 in gastric cancer was unclear.
  • The study found that solamargine inhibits gastric cancer cell growth and metastasis by downregulating STAT3 signaling and reducing PD-L1 expression, suggesting it could be a promising treatment strategy for gastric cancer.

The novel grading system developed by the International Association for the Study of Lung Cancer (IASLC) for clinical stage IA lung adenocarcinomas has demonstrated remarkable prognostic capabilities. Notably, tumors classified as grade 3 have been associated with poor prognostic outcomes, thereby playing a crucial role in the formulation of personalized surgical strategies. The objective of this study is to develop a radiomics nomogram that utilizes the optimal volume of interest (VOI) derived from high-resolution CT (HRCT) scans to accurately predict the presence of grade 3 tumors in patients with clinical IA lung adenocarcinomas.

Article Synopsis
  • - Drug-related problems (DRPs) in critically ill patients can lead to higher mortality rates, but the involvement of critical care pharmacists (CCPs) in medical teams improves healthcare quality and reduces these risks.
  • - Research shows that CCPs can effectively evaluate medication orders, minimize adverse drug events, and decrease hospital stays, proving to be more efficient in medication reconciliation than physicians.
  • - Despite these advantages, there's a lack of clear guidelines for CCP roles; establishing a structured workflow is needed for better integration into patient care, with proactive involvement in all phases of medication management, from pre-round evaluations to post-ICU follow-up.

Electronic address:

Aims: The dysregulated Wnt/β-Catenin signaling pathway leads to occurrence of various diseases, and abnormal activation of β-Catenin is a major characteristic of human HCC. FZD7 is a positive regulator of the Wnt/β-catenin signaling pathway, and its upregulation is related to increase of β-catenin expression and carcinogenesis in human HCC. However, mechanisms underlying FZD7 upregulation in HCC remain elusive.

The mechanism of the interaction between the signaling molecule hydrogen sulfide (HS) and mitochondria and its related diseases is difficult to elusive. Thus it is urgent to develop effective methods and tools to visualize HS in mitochondria and in vivo. In this work, a robust mitochondrial-targeting NIR fluorescence "turn-on" fluorescent probe, NIR1, was reported, by adopting a Changsha-OH near-infrared (NIR) dye as the NIR fluorophore, a 2,4-dinitrophenyl (DNB) moiety as both the responsive site of the HS and the fluorescence quenching group of the NIR fluorophore, and an oxygen onium ion site as the mitochondria-targeting group, for the detection and analysis of HS in living Raw 264.

Disulfide-Rich Self-Assembling Peptides Based on Aromatic Amino Acid.

Small

January 2025

The Affiliated XiangTan Central Hospital of Hunan University, School of Biomedical Sciences, Hunan University, Changsha, Hunan, 410082, P. R. China.

Article Synopsis
  • Aromatic residues in peptides significantly influence self-assembly through interactions such as π-π stacking and hydrophobic forces, but there is limited research on the effects of single aromatic amino acids in this process.
  • This study examines how different aromatic amino acids affect the folding, self-assembly properties, and rheological behaviors of disulfide-rich peptides, revealing that these interactions play a key role in their critical aggregation concentration (CAC).
  • Additionally, the biocompatibility of the resulting hydrogels is tested for potential use in 3D cell cultures, showing that the F1-ox hydrogel supports cell viability and nutrient exchange due to its porous structure.
