Luminescent Properties and Cytotoxic Activity of 2-phenylbenzoxazole Fluorosulfate Derivatives.

The synthesis of 2-phenylbenzoxazole fluorosulfate derivatives was carried out using the SuFEx reaction. To study the anticancer properties of the obtained compounds, the cell lines PC-3 (obtained from prostate adenocarcinoma), BT-474, and MCF-7 (both obtained from breast carcinoma) were used. The cytotoxicity on murine 3T3L1 embryonic was also investigated.

Electric activity of the adult European river lamprey.

Lampreys possess electroreceptors distributed across their body surface, yet the only previously documented electric signals in these animals were ventilatory myograms, hypothesized to enable short-range electrolocation. Here, we report the discovery of biphasic, spike-like electric signals in free-swimming lampreys, recorded in both moving and immobile individuals. These signals exhibited amplitudes several dozen times greater than ventilatory signals, with durations approximately half as long.

Anisotropic Vanadium Dioxide Nanogratings by Direct Laser-Induced Periodic Surface Structuring (LIPSS).

Thermochromic vanadium dioxide (VO) films have attracted enormous attention in the past decade owing to their high potential in active optical filters, sensors, anevices. VO patterned at the micro- and nanoscale is an evident route toward next-generation devices justifying the need for scalable, straightforward, and high-performing nanofabrication technologies being easily applied for this material. Herein, precise and nondestructive femtosecond laser nanopatterning of the VO films in both direct ablation and plasmon-assisted self-organization regimes is reported under ambient conditions.

Co-ligand tuning of MOF structural anisotropy for giant optical birefringence.

The control of the structural anisotropy of metal-organic frameworks (MOFs) by tuning their co-ligand composition to enhance the birefringence properties is demonstrated. A set of Cd-based MOFs with three co-ligands and HTCPB were synthesised. We experimentally revealed the evolution of the MOF structural anisotropy and birefringence, which was equal to maximal Δ = 0.

Molecular Profiling and FTIR Characterization of Wheat Germ Oil, Supported by the Screening of Its Anti-Inflammatory and Cytotoxic Properties.

Wheat germ oil (WGO), derived from the nutrient-dense germ of wheat kernels, is a functional bioactive product, known for its rich composition of essential fatty acids, sterols, tocopherols, and polyphenols. This study aimed to comprehensively profile the molecular and therapeutic properties of WGO, focusing on its antioxidant, cytotoxic, and anti-inflammatory activity. Using advanced analytical techniques such as gas chromatography-mass spectrometry (GC-MS), Fourier Transform Infrared (FTIR) spectroscopy, and fluorescence analysis, WGO was shown to contain high levels of linoleic acid (45.
