Although, NPs have potential to improved plant resistance against abiotic stress, increased nutrient usage efficiency, and sustenance of agricultural production. However, reactions of NPs in soil matrices, particularly their movement, perseverance, and biogeochemical reactions in soil-plant system under heavy metals (HMs) were not well understood. Therefore, this review presents the latest research in order to clarify the molecular interactions, beneficial transformations, and detoxification processes of NPs in plants and evaluates their roles in these processes. It further aims to quantify the benefits and risks, and give future directions for NPs design and applications in environmental remediation and agriculture. NPs significantly enhanced agricultural outcomes through mechanisms such as regulating HMs uptake, boosting antioxidant enzyme activity (up to a 60% increase), altering soil properties, and optimizing physiological metabolism. NPs amendments raised crop output by 20-55% while reducing disease and nutrient leaching to 50% and 30%, respectively, and improving the soil's carbon sink by 15%. Meanwhile, green-synthesized nanomaterials offer eco-friendly alternatives in remediation through processes like adsorption, oxidation, coprecipitation, ion-exchange, photocatalysis, and nanophytoremediation, achieving 100% pollutant removal efficiency for elements like hexavalent chromium using iron NPs. However, challenges such as NPs accumulation in food chains, potential toxicity to non-target species, and physiological disruptions necessitate solutions like microbiome co-delivery and stimuli-responsive systems to balance safety and effectiveness. In order to increase the available resources and address the worldwide food safety issue, the use of NPs in agroecosystems might be a crucial step towards sustainable farming. Therefore, the influence of NPs on soil, and plant antioxidant defense systems and oxidative stress activation under HMs should be studied using molecular, physiological, and biochemical techniques. For this purpose, real-time polymerase chain reaction (RT-PCR) analysis, illumina MiSeq sequencing, pyrosequencing analysis, metagenomics, metabolomics, proteomics, and functional assays etc. could be most useful for NPs risk/benefit evaluation.

Persistent, Mobile, and Toxic (PMT) and very Persistent and very Mobile (vPvM) substances pose a significant environmental threat due to their widespread distribution, persistence, and potential toxicity. While previous studies have used reversed-phase (RP) and hydrophilic interaction liquid chromatography (HILIC) to extend analyte coverage, this study uniquely integrates a dual-chromatographic approach with multi-sorbent solid phase etration (SPE) and machine-learning-based retention time indices to rigorously minimize false positives and enhance confidence in suspect screening of PMT/vPvM substances. Two independently optimized LC methods (RP and HILIC) were applied in parallel to the same SPE extract to identify potential chromatographic blind spots. We applied this robust framework to systematically screen surface water and wastewater treatment plant (WWTP) effluent across a water catchment in Uppsala, Sweden. The RP and HILIC workflows, applied as independent chromatographic runs, identified 84 compounds after multi-stage filtering (with retention time indices (RTI) correction applied only to the RP data), with 27% and 48% uniquely detected by HILIC and RP, respectively, highlighting analytical blind spots overcome by this integrated approach. Strategic site selection, encompassing upstream rural zones, on-site sewage facilities, and major WWTP discharge points, demonstrated how local land use impacts PMT/vPvM profiles. This comprehensive method provides a powerful tool for environmental monitoring and regulatory surveillance of PMT/vPvM compounds.

Combined hypomethylating agent (HMA) plus venetoclax (Ven) therapy enables most older patients with acute myeloid leukemia (AML) to achieve clinical remission. Key objectives are now aimed at developing new triplet combinations to circumvent mechanisms of resistance and extend remission longevity and, by extension, survival. Genomically agnostic approaches combine hypomethylating agents and venetoclax (HMA-Ven) with novel agents directed at oncogenic pathways critical for leukemic cell survival, proliferation, metabolism, or differentiation. Challenges faced in the development of new HMA-Ven triplets include competition from targeted inhibitors, biological heterogeneity of AML, potential for additive toxicity, reduced efficacy from modifications to the HMA-Ven backbone, and the higher bar for success in older AML beyond the current standard of care.

Cancers, such as cervical carcinoma, are one of the most significant diseases affecting human health and histone deacetylases (HDACs) are striking targets in current antitumor drug development. Compared to pan-HDAC inhibitors with potential toxicity, the development of selective HDAC6 inhibitors (sHDAC6is) is a major research focus. In this study, a series of derivatives bearing an aroylpyrrole core were designed and synthesized using a scaffold-hopping strategy. Among these, the best compound 4-benzoyl-1-(4-fluorobenzyl)-N-(7-(hydroxyamino)-7-oxoheptyl)-1H-pyrrole-2-carboxamide (10g) inhibited HDAC6 with an IC50 of 3.9 nM and superior selectivity over HDAC1 compared to ACY-1215. In vitro, these aroylpyrroles demonstrated promising antiproliferative activities against Hela and SiHa tumor cells. 10g also showed superior metabolic stability compared to ACY-1215 in a microsomal stability study. In summary, this work highlighted the therapeutic potential of aroylpyrrole-based sHDAC6 inhibitors and provided a valuable lead compound in treating cervical cancer.

Herbal medicine has historically played an important role in healthcare in Ethiopia. However, its use in prehospital settings, where individuals self-administer herbal remedies before seeking formal healthcare, is not well understood. There is limited evidence of its prevalence, factors associated with its use, and potential safety implications. Therefore, this study aimed to assess the prevalence of prehospital herbal medicine use, identify determinants, and explore potential safety risks among patients admitted to Jimma Medical Center (JMC) in Southwestern Ethiopia. A hospital-based cross-sectional study was conducted among 217 patients admitted to the medical wards of Jimma Medical Center (JMC) between June and September 2021. Data were collected using a pretested, structured questionnaire. And a literature review was conducted to evaluate the potential toxicity and herb-drug interactions associated with the herbal medicines used by the patients. The data were analyzed using SPSS version 21. Descriptive statistics were used to summarize the findings, while bivariate and multivariate logistic regression analyses were employed to identify factors associated with pre-hospital herbal medicine use. A P-value < 0.05 was considered statistically significant. The prevalence of prehospital herbal medicine use was 34%. Most patients (78.7%) did not inform healthcare providers about their herbal use. Additionally, prehospital herbal medicine usage is influenced by age (AOR = 0.281, 95% CI: 0.115-0.683), secondary educational level (AOR = 2.7, 95% CI: 1.101-6.485), and lack of insurance coverage (AOR = 2.1, 95% CI: 1.083-4.004). This indicates that demographic, socioeconomic, and cultural factors jointly influence prehospital herbal medicine use. The study also found that Ocimum gratissimum, Ruta chalepensis, Croton macrostachyus, Zingiber officinale, Eucalyptus globulus, Echinops kebericho, and Carica papaya were the most utilized herbal medicines in the studied area. Furthermore, the literature review revealed potential herb-drug interactions and toxicity risks, especially with Zingiber officinale, Carica papaya, Eucalyptus globulus, and Ruta chalepensis. Prehospital use of herbal medicines was relatively high and often undisclosed to healthcare providers, raising safety concerns due to potential toxicities and herb-drug interactions. Age, education, and insurance status significantly influenced herbal medicine use. These findings emphasize the need for healthcare providers to proactively inquire about herbal medicine use during patient assessments, as well as for community awareness programs promoting the safe use of herbal remedies.

What do emerging PFAS tell us that the classic ones did not? Insights from in vitro assays.

Lymphoma is a malignant tumor caused by abnormal proliferation of lymphocytes in the lymphatic system. Conventional treatments for lymphoma often have limitations, and new therapeutic strategies need to be explored. Realgar is an ancient Chinese medicine that has been used for centuries to treat a variety of ailments due to its therapeutic potential for various diseases, including cancer. However, it is a time-consuming waste and has a low absorption rate in the gastrointestinal tract, so it has the disadvantages of oral dose, potential toxicity, and low bioavailability. Recently, the development of nanotechnology has promoted the nanization of realgar particles, which have better physicochemical properties and higher bioavailability. The antitumor activity of Realgar nanoparticles against lymphoma has been demonstrated in preclinical studies. Realgar nanoparticles exhibit cytotoxic effects by inducing apoptosis and inhibiting the growth and proliferation of lymphoma cells. Moreover, these nanoparticles exert immunomodulatory effects by enhancing the activity of immune cells and promoting the cytotoxicity of T lymphocytes against lymphoma cells. Additionally, realgar nanoparticles have been shown to inhibit tumor angiogenesis, thereby restricting the blood supply and nutrient availability to lymphoma cells as exhibited in this patent comprehensive review. Despite promising preclinical data, further research on the role and mechanism of realgar nanoparticles in the treatment of lymphoma remains to be studied. Moreover, the translation of these findings into clinical practice requires rigorous evaluation through well-designed clinical trials. Realgar nanoparticles hold great potential as a novel therapeutic approach for lymphoma, and their development may contribute to the advancement of precision medicine in the field of oncology.
