Liquid Hopfield model: Retrieval and localization in multicomponent liquid mixtures.
Proc Natl Acad Sci U S A
November 2024
Article Synopsis
- Biological mixtures like cellular cytoplasm consist of various components that lead to the formation of organized structures, such as liquid phases with specific compositions.
- A new model called the liquid Hopfield model is introduced to understand how these multicomponent liquids can achieve desired compositions through certain interactions.
- The study reveals that nonlinear repulsive interactions are essential for retrieving these structures, highlighting a balance between the ability to retrieve target compositions and the tendency of mixtures to simplify into fewer components at low temperatures.
Thanks to an environmentally friendly physical treatment of high purity graphite, a good control of the structure of graphene nanoparticles (GNPs) has been obtained with the production of stable and reproducible GNPs water dispersions. The preparation protocol entailed ball-milling of synthetic graphite followed by sonication in water and centrifugation/separation procedures. This way, two different GNPs samples with slightly different structural characteristics were harvested: TOP60, showing an average lateral size of the graphene layers
Article Synopsis
- The axillofemoral bypass is primarily used to address specific aortoiliac blockages, though it can also be done in reverse for occlusive arterial disease.
- The study reports a successful hybrid treatment for a para-anastomotic aortic arch pseudoaneurysm involving bilateral femoroaxillary bypasses, thromboexclusion of all supra-aortic trunks, and the use of an endograft to cover the aortic arch.
Cardiogenic shock with acute hemodynamic decompensation may be one of the most serious risks in patients affected by ventricular tachycardia (VT). Its proper identification may have important implications in terms of pharmacological management, as might procedural planning in case of patients undergoing catheter ablation. We describe a case series of patients with provisional strategies for circulatory support in VT ablation, including the use of venoarterial extracorporeal membrane oxygenation (VA-ECMO) and vascular accesses in the electrophysiology lab but no initial ECMO activation due to an estimated intermediate pre-procedural risk from the case-series population.

- - Hepatocellular carcinoma (HCC) is a major form of liver cancer, with early-stage treatment options like surgery and transplantation, while advanced stages often require systemic therapies that can have significant side effects.
- - The study investigates the effects of delta-tocotrienol (δ-TT) on HCC cells, particularly its role in inducing apoptosis, oxidative stress, and autophagy mechanisms within the HepG2 cell line.
- - Findings suggest that δ-TT promotes cell death in HCC by inducing mitochondrial dysfunction and selective autophagy, which could be harnessed as a new treatment strategy for advanced HCC.
