Mass-spectrometry-based quantitative proteomic analysis reveals that methylglyoxal and carnosine influence oxidative stress and RNA-processing associated proteins in renal proximal tubule epithelial cells.

Background: Tubular injury triggered by hyperglycemia is an important pathological characteristic in diabetic nephropathy (DN). Accumulated advanced glycation end products and their precursor methylglyoxal (MGO), contribute to the development of DN. Carnosine has been shown to prevent the development of DN but the underlying mechanism still needs to be studied in depth.

iRGD-TRP-PK1-modified red blood cell membrane vesicles as a new chemotherapeutic drug delivery and targeting system in head and neck cancer.

Therefore, a targeted delivery system that can transport the drug to the pathological site while minimizing damage to healthy tissues is urgently needed.

Robust ferromagnetism in wafer-scale FeGaTe above room-temperature.

The discovery of ferromagnetism in van der Waals (vdW) materials has enriched the understanding of two-dimensional (2D) magnetic orders and opened new avenues for fundamental physics research and next generation spintronics.

Tunable Anomalous Hall Effect in a Kagomé Ferromagnetic Weyl Semimetal.

Emerging from the intricate interplay of topology and magnetism, the giant anomalous Hall effect (AHE) is the most known topological property of the recently discovered kagomé ferromagnetic Weyl semimetal CoSnS with the magnetic Co atoms arranged on a kagomé lattice. Here it is reported that the AHE in CoSnS can be fine-tuned by an applied magnetic field orientated within ≈2° of the kagomé plane, while beyond this regime, it stays unchanged. Particularly, it can vanish in magnetic fields parallel to the kagomé plane and even decrease in magnetic fields collinear with the spin direction.

The NRF2-CARM1 axis links glucose sensing to transcriptional and epigenetic regulation of the pentose phosphate pathway in gastric cancer.

Cancer cells autonomously alter metabolic pathways in response to dynamic nutrient conditions in the microenvironment to maintain cell survival and proliferation. A better understanding of these adaptive alterations may reveal the vulnerabilities of cancer cells. Here, we demonstrate that coactivator-associated arginine methyltransferase 1 (CARM1) is frequently overexpressed in gastric cancer and predicts poor prognosis of patients with this cancer.

Outcomes and complications of hemodialysis in patients with renal cancer following bilateral nephrectomy.

Objectives: The management of patients undergoing bilateral nephrectomy for renal cancer presents significant challenges, particularly in addressing hypotension, anemia, and tumor recurrence during hemodialysis.

In the presented case, post-nephrectomy, the patient experienced frequent hypotension and anemia during dialysis, improving with erythropoietin-stimulating agents and subsequently with rosuvastatin.

Strong interlayer magnetic exchange coupling in LaNiO revealed by inelastic neutron scattering.

After several decades of studies of high-temperature superconductivity, there is no compelling theory for the mechanism yet; however, the spin fluctuations have been widely believed to play a crucial role in forming the superconducting Cooper pairs. The recent discovery of high-temperature superconductivity near 80 K in the bilayer nickelate LaNiO under pressure provides a new platform to elucidate the origins of high-temperature superconductivity. We perform elastic and inelastic neutron scattering studies on a polycrystalline sample of LaNiO at ambient pressure.

Observation of In-Gap States in a Two-Dimensional CrI/NbSe Heterostructure.

Low-dimensional magnetic structures coupled with superconductors are promising platforms for realizing Majorana zero modes, which have potential applications in topological quantum computing. Here, we report a two-dimensional (2D) magnetic-superconducting heterostructure consisting of single-layer chromium diiodide (CrI) on a niobium diselenide (NbSe) superconductor. Single-layer CrI nanosheets, which hold antiferromagnetic (AFM) ground states by our first-principles calculations, were epitaxially grown on the layered NbSe substrate.
