Genomic DNA was extracted, and all exons of PAX9 (Exons 1,2, 3, and 4) and MSX1 (Exons 1 and 2) were amplified using PCR. The Sanger sequencing technique was used to detect genetic variants, which were analyzed for their clinical significance and evolutionary conservation.

The combustion of fossil-based fuels poses serious risks to both the environment and human health due to the release of greenhouse gases. This study aimed to assess the fatty acid methyl ester (FAME) composition, viscosity, acid number, and chemical metal elements present in algal biodiesel produced through a transesterification bioprocess. Nanoparticles (NPs) offer a promising solution to current challenges in biomass utilization. Their advantages include high selectivity, energy efficiency, effective time management, and reduced costs. Biodiesel conversion yield, along with its physical and chemical properties, was analyzed using GC-MS and a multi-element oil analyzer. The highest conversion yield of 98.9% was achieved using a mixed catalyst-nanocatalyst system (NaOH + CaO + ZnO) under optimal conditions: a 1:4 oil-to-methanol volumetric ratio, 1.0% catalyst concentration, reaction temperature of 40°C, and stirring speed of 320 rpm. A significant difference was observed in the viscosity and acid value between biodiesel produced using a single catalyst and that produced using catalyst mixtures. Furthermore, the concentrations of chemical metal elements (Na, Ca, Mg, Cu, Fe, Zn, Ag, Al, P, Pb, B, Cr, Mn, Sn, Mo, Si, Ba, Ni, Ti, and V) were lower in biodiesel derived from mixed nanocatalyst-catalyst combinations (NaOH + ZnO, NaOH + CaO, and NaOH + CaO + ZnO) compared to the single-catalyst system (NaOH). Overall, biodiesel produced using the combined catalyst and nanocatalyst approach exhibited reduced metal element content and superior yield compared to biodiesel obtained using a single catalyst.

This study aimed to investigate the effects of administering different doses of Xamoterol, a partial β1-adrenergic agonist, directly into the NAc shell, to understand its impact on anxiety-related processes and the retrieval of emotional memory. Forty adult male Wistar rats were bilaterally implanted with cannulas targeting the NAc shell. The rats received intra-accumbal Xamoterol at doses of 0.01, 0.1, or 1 μg/1 μl (saline). Five minutes after drug administration, anxiety-like behavior was tested using the Elevated Plus Maze (EPM). Twenty-four hours later, an EPM retention test was conducted to assess emotional memory retrieval. In addition, an open-field test was used to measure spontaneous locomotor activity. One-way ANOVA results showed that intra-accumbal Xamoterol (0.1 and 1 μg) significantly decreased anxiety-like behavior on the EPM. Conversely, head-dipping behavior (a risk assessment measure) was significantly increased at 0.01 and 0.1 μg doses of Xamoterol, which can be interpreted as an anxiolytic effect. Furthermore, higher doses of Xamoterol (0.1 and 1 μg) led to better emotional memory performance compared to the control group.

In this study, we successfully fabricated a novel two-dimensional (2D) covalent organic framework (COF) nanomaterial. This COF was loaded with tamoxifen (TMX) and surface-modified with folic acid (FA) to achieve effective targeting for breast cancer therapy. The resulting construct, TMX@COF-FA, was characterized using PXRD, FTIR, ¹³C NMR, CHNS analysis, BET surface area analysis, TGA, UV-Vis spectroscopy, SEM, and EDX analysis. The COF carrier demonstrated a high drug encapsulation efficiency of approximately 82%. Furthermore, it exhibited a pH-responsive drug release profile, with a significantly higher release rate at pH 5.4 compared to pH 7.4, which is ideal for the acidic tumor microenvironment. Cell viability studies revealed that TMX@COF-FA induced about 90% cell death in MCF-7 breast cancer cells, while showing minimal cytotoxicity in L929 fibroblast cells. The mechanism of cell death was investigated using AO/EtBr dual staining, ROS detection assays, flow cytometry (FACS), and qRT-PCR. Collectively, our findings demonstrate that the FA-conjugated COF can efficiently deliver TMX to MCF-7 cells via folate receptor-mediated endocytosis, leading to potent cancer cell destruction. This study underscores the potential of functionalized COFs as promising targeted drug delivery platforms for breast cancer treatment.</p>","PeriodicalId":520584,"journal":{"name":"Cellular and molecular biology (Noisy-le-Grand, France)","volume":"72 1","pages":"24-32"},"PeriodicalIF":0.0,"publicationDate":"2026-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146184136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
