The History of the Discovery of Vitamin K

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 3, September 2026.
ABSTRACT Vitamin K was discovered during the 1930s when a strange haemorrhagic disorder was observed in chickens fed a cholesterol‐free diet. A fat‐soluble agent, present in green leafy vegetables and hog liver, was able to restore haemostasis in the chickens.

On the History of Hepatic Vein Catheterization

Liver International, Volume 46, Issue 9, September 2026.
ABSTRACT Hepatic vein catheterization (HVC) in man was first performed 80 years ago in the wake of right‐sided heart catheterization. Several new methods, recognitions and concepts followed, especially the indirect Fick‐method for determination of splanchnic blood flow. Five years passed before pressure measurements were performed and routine HVCs were

MEOX1 Coordinates Autocrine‐Paracrine Programs via SPHK1/S1P to Promote Lymph Node Metastasis in Ovarian Cancer

Advanced Science, Volume 13, Issue 43, 3 August 2026.
In ovarian cancer, MEOX1 activates the SPHK1/S1P pathway to promote both tumor progression and tumor–stroma crosstalk. MEOX1‐dependent signaling drives CAF activation, enhances VEGF‐C expression, and stimulates lymphangiogenesis, ultimately facilitating lymph node metastasis.

Asymmetrically Coordinated Dual‐Atom Manganese Contrast Agents Enabling High‐Efficiency T1 Enhanced MRI for Precise Tumor Visualization

Advanced Science, Volume 13, Issue 43, 3 August 2026.
A novel dual‐atom manganese MRI contrast agent (Mn‐BN) with a unique asymmetric coordination geometry provided a promising platform for sensitive and specific tumor imaging. In mice model, Mn‐BN nanoparticles precisely functioned as both a primary tumor‐specific enhancer in subcutaneous models and a hepatocyte‐specific agent in liver metastases models ...

Triple‐Negative Breast Cancer Cells Utilize IL8 and CXCL1 to Suppress NK Cells’ Function and Facilitate Cancer Metastasis

Advanced Science, Volume 13, Issue 44, 7 August 2026.
Triple‐negative breast cancer (TNBC) cells evade natural killer (NK) cell immunity by secreting IL8 and CXCL1. These chemokines suppress NK cells’ function via CXCR1/2 and enhance cancer cells’ survival through PD‐L1 upregulation and BCL‐2 anti‐apoptotic signaling.
