Metabolomic and Proteomic Analyses Unveil That Polyethylene Glycol-Polycaprolactone-Loaded Curcumin Nanoparticles Induce Mitochondrial Dysfunction and Metabolic Reprogramming to Suppress Melanoma Growth.

Melanoma is highly dependent on cellular metabolism, but current treatments show limited effectiveness. Despite the promising antitumor properties of curcumin, its clinical utility is limited by its poor bioavailability and potential systemic toxicity. To address these challenges, we formulated curcumin-loaded polyethylene glycol-polycaprolactone (PEG-PCL) nanoparticles, denoted as PEG-PCL@Cur.

A Unique Approach: Biomimetic Graphdiyne-Based Nanoplatform to Treat Prostate Cancer by Combining Cuproptosis and Enhanced Chemodynamic Therapy.

Purpose: Current treatment approaches for Prostate cancer (PCa) often come with debilitating side effects and limited therapeutic outcomes. There is urgent need for an alternative effective and safe treatment for PCa.

Methods: We developed a nanoplatform to target prostate cancer cells based on graphdiyne (GDY) and a copper-based metal-organic framework (GDY-CuMOF), that carries the chemotherapy drug doxorubicin (DOX) for cancer treatment.

Laser Linewidth Analysis and Filtering/Fitting Algorithms for Improved TDLAS-Based Optical Gas Sensor.

Tunable Diode Laser Absorption Spectroscopy (TDLAS) has been widely applied in in situ and real-time monitoring of trace gas concentrations. In this paper, an advanced TDLAS-based optical gas sensing system with laser linewidth analysis and filtering/fitting algorithms is proposed and experimentally demonstrated. The linewidth of the laser pulse spectrum is innovatively considered and analyzed in the harmonic detection of the TDLAS model.
