The therapeutic role of Coccinia grandis in flavor-enhancing high-lipid diet-induced chronic kidney disease: a dual role of NF-kB and TGF-β/smad in renal fibrosis.

Background: Coccinia grandis (CG), a plant used as traditional medicine, possesses antioxidant, anti-inflammatory, and anti-fibrotic activities. Chronic kidney disease (CKD) and renal fibrosis are public health issues, further promoted by monosodium glutamate in high-lipid diets (MH) via oxidative stress and inflammation. CG could potentially alleviate MH-induced CKD by modulating cell signaling.

Criticality and Magnetic Phases of Ising Shastry-Sutherland Candidate Holmium Tetraboride.

Frustrated magnetic systems arising in geometrically constrained lattices represent rich platforms for exploring unconventional phases of matter, including fractional magnetization plateaus, incommensurate orders and complex domain dynamics. However, determining the microscopic spin configurations that stabilize such phases is a key challenge, especially when in-plane and out-of-plane spin components coexist and compete. Here, we combine neutron scattering and magnetic susceptibility experiments with simulations to investigate the emergence of field-induced fractional plateaus and the related criticality in a frustrated magnet holmium tetraboride (HoB) that represents the family of rare earth tetraborides that crystalize in a Shastry-Sutherland lattice in the ab plane.

Putrescine modulates alternative splicing of gonadotropin hormone-releasing hormone (GnRH) through differential regulation of splicing factors.

Adsorption-Site- and Orientation-Dependent Magnetism of a Molecular Switch on Pb(100).

Tin phthalocyanine (SnPc) has been studied on superconducting Pb(100) using scanning tunneling microscopy and spectroscopy. Isolated molecules adsorb with their Sn ion below (SnPc↓) or above (SnPc↑) the molecular plane. These geometries lead to different adsorption sites, molecular orientations, and energies of the frontier orbitals.

Quantum quench dynamics of geometrically frustrated Ising models.

Geometric frustration in two-dimensional Ising models allows for a wealth of exotic universal behavior, both Ising and non-Ising, in the presence of quantum fluctuations. In particular, the triangular antiferromagnet and Villain model in a transverse field can be understood through distinct XY pseudospins, but have qualitatively similar phase diagrams including a quantum phase transition in the (2+1)-dimensional XY universality class. While the quantum dynamics of modestly-sized systems can be simulated classically using tensor-based methods, these methods become infeasible for larger lattices.

Where do the pyrene molecules reside within the surface active ionic liquid micelles in presence of sodium alginate?

Pyrene fluorescence in aqueous solutions of two surface active ionic liquids, namely, 1-decyl-3-methylimidazolium chloride, and 1-hexadecyl-3-methylimidazolium chloride was investigated in presence of a biopolymer sodium alginate. The principal objective of this study was to explore the influence of the length of the hydrocarbon tails of these surface active ionic liquids on the possible location of the probe (pyrene) molecules in presence of the additive. While an abrupt decrease in the values of the ratio of the intensity of the first vibronic band to that of the third band of pyrene emission spectrum with concentration was observed for 1-hexadecyl-3-methylimidazolium chloride in presence of sodium alginate like the polymer-free case reported earlier, there was a peculiar reversal for 1-decyl-3-methylimidazolium chloride + sodium alginate.

Adipocytes Promote Endometrial Cancer Progression Through Activation of the SIRT1-HMMR Signaling Axis.

Adipocyte is a predominant component of the omental adipose tissue that influences the tumor microenvironment and increases the risk of endometrial cancer progression (EC), however, little is known about the underlying mechanism. In this study, using a co-culture model, we found that the adipocyte-EC cell interaction promoted SIRT1 signaling in vitro and in vivo xenograft mice models. Furthermore, immunostaining of SIRT1 protein showed significantly higher expression of SIRT1 in endometrial cancer patients than in normal endometria.

The present study firstly highlights the age-specific variation in the polyamine and their corresponding biosynthetic enzymes in the ovary during aging, and further, the study focuses on the effect of polyamines, putrescine, and agmatine, in young female mice.

Structure of higher-order interactions in social-ecological networks through Q-analysis of their neighbourhood and clique complex.

This paper studies higher-order interactions in social-ecological networks, which formally represent interactions within the social and ecological units of an ecosystem. Many real-world social ecosystems exhibit not only pairwise interactions but also higher-order interactions among their units. Therefore, the conventional graph-theoretic description of networks falls short of capturing these higher-order interactions due to the inherent limitations of the graph definition.
