This approach combines effective matrix removal in silicate rock samples through the formation of insoluble fluorides during microwave-assisted digestion and the volatilization of silicon as SiF₄ with the capability of ICP-MS to quantify target isotopes at very low signal intensities (10-100 cps) using optimized acquisition parameters. Moreover, the ability to perform ICP-MS measurements at such low signal intensities also enables matrix reduction in other sample types, such as ores, through simple dilution while maintaining sufficient analytical sensitivity. Since proposed strategy employs fast microwave dissolution of PGEs together with their reliable and accurate determination, without the need for complex and time-consuming matrix-separation procedures such as ion-exchange chromatography or tellurium co-precipitation, the analytical workflow is significantly simplified, and the overall analysis time is reduced several-fold compared with conventional methods. At the same time, detection and quantitation limits are below 0.1 and 0.5 ng/g, respectively, for all analytes except Pd, for which the corresponding limits are 0.18 and 0.9 ng/g, enabling the determination of PGEs in variety rock types. The new method was verified using six rocks certified reference materials (CRMs) MUH-1 (harzburgite), NCS-DC73354/GBW07290 (peridotite), OKUM (komatiite), and UMT-1 (ultramafic ore tailings), WMS-1a (massive sulfide) and NCS-DC73356/GBW07292 (chromitite).

Unlike conventional metal-oxide gas sensors operating at elevated temperatures, the formation of a p-n heterojunction between p-type Ag₂O and n-type ZnO facilitates efficient charge separation and significantly lowers the activation energy for acetone oxidation, enabling enhanced sensing at ambient conditions. The structural and morphological properties were characterized by X-ray diffraction, FESEM, XPS, and FTIR. The sensing performance was achieved by coating the modified fiber cladding with ZnO@Ag₂O, where evanescent-field interaction and adsorption-induced optical property changes govern the sensing mechanism, as validated by COMSOL Multiphysics simulations. The flower-like morphology provides a larger surface area and abundant active sites, resulting in superior sensing performance compared to pristine ZnO nps. The performance parameters of the developed sensor include a sensitivity of 11.37/ppm, a limit of detection of 0.85 ppm, and response and recovery times of 14 s and 60 s, respectively, compared to pristine ZnO nps.

Although neuroscience implicates coordinated prefrontal cognitive control and hippocampal-temporal systems in conflict resolution and semantic memory updating, direct neural evidence of their interaction during conceptual change remains limited.

Learners exhibited greater conceptual change success during weak than radical restructuring, with enhanced BOLD activation in the superior, middle, and inferior frontal gyri (SFG, MFG, IFG), Hippocampus (HIP), and Superior Temporal Gyrus (STG) during successful versus unsuccessful conceptual change.

Ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) analysis was conducted to tentatively annotate and characterize the phytochemicals present in this plant extract. The in vitro anti-inflammatory activity was investigated by inhibiting BSA denaturation. Acute and sub-acute toxicity were evaluated orally in Albino mice, and anti-inflammatory and analgesic properties were assessed in Wistar rats. Molecular docking was performed to investigate interactions between the tentatively identified compounds and relevant therapeutic targets, while ADMET (absorption, distribution, metabolism, excretion, and toxicity) predictions were used to assess their pharmacokinetic properties and potential toxicity.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The CrE yielded 19.11 ± 1.07% and was rich in polyphenols (244.65 ± 2.36 μg GAE/mg CrE) and flavonoids (41.45 ± 0.38 μg QE/mg CrE). The results of UHPLC-HRMS analysis showed twenty tentatively identified compounds, including flavonoids and their derivatives (luteolin, naringenin, etc.), phenolic acid (chlorogenic acid), iridoid glycoside (harpagide), phenylethanoid glycosides (teucrioside, verbascoside and poliumoside), triterpenoids (maslinic acid) and a cyclitol and cyclohexanecarboxylic acid (quinic acid). In vitro assays demonstrated a significant anti-inflammatory activity with an IC&lt;sub&gt;50&lt;/sub&gt; of 437.80 ± 21.11 μg/mL. In vivo studies demonstrated that the CrE did not exhibit any acute or sub-acute toxicity effects in the tested animals.

Uterine morphology, embryo loss rate, blood viscosity, and histopathology (H&E staining, immunohistochemistry, immunofluorescence) were assessed. Angiogenic (VEGFA, p-VEGFR2, HIF-1α) and receptivity markers (Integrin β3, LIF, HOXA11) were evaluated by western blot and RT-qPCR. UPLC-Q-TOF-MS/MS was used to identify components distributed in blood and uterus. Molecular docking and molecular dynamics were performed to predict potential binding affinity between core bioactive components and vascular-related target proteins. Zebrafish models (vascular injury, erythrocyte injury and hemorrhage) were utilized to observe pro-angiogenic and hemostatic effects of JAD.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;JAD reduced embryo loss, restored uterine microvascularization (CD31, α-SMA) and improved hemorheology in rats. These phenotypic changes coincided with elevated VEGFA/p-VEGFR2, suppressed HIF-1α and greater placental angiogenesis. Meanwhile, higher pinopod density and upregulated Integrin β3, LIF, and HOXA11 collectively indicated improved endometrial receptivity after treatment. Molecular docking and molecular dynamics simulations predicted stable binding interactions between 19 major bioactive components of JAD and target proteins FLT1 and VWF. In zebrafish, JAD (12.5-200 μg/mL) and its representative constituents (e.g., adenosine, ferulic acid) stimulated angiogenesis and erythropoiesis while mitigating hemorrhage, correlating with elevated VEGFA/p-VEGFR2 protein and vascular-related mRNA levels (vwf, vegfa, flt1, kdr, kdrl).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;The anti-abortive effects of JAD are associated with the restoration of uterine vascular homeostasis, endometrial receptivity and hemodynamics.
