Here, we evaluated the profiles of antibiotic resistome in multiple media on Inexpressible Island, Terra Nova Bay, Antarctica. Average concentrations of ARGs in intracellular DNA (iARGs) among water (3.98 × 10<sup>6</sup> copies/L), soil (3.41 × 10<sup>7</sup> copies/kg), and penguin guano (7.04 × 10<sup>7</sup> copies/kg) were higher than those of ARGs in extracellular DNA (eARGs) among water (1.99 × 10<sup>4</sup> copies/L), soil (1.75 × 10<sup>6</sup> copies/kg), and penguin guano (8.02 × 10<sup>6</sup> copies/kg). It was indicated that the transmission of ARGs across different media occurs with around 77.8% of iARGs from soil and 86.7% of iARGs from penguins observed in water, and 80.7% of iARGs and 56.7% of eARGs from penguins found in soil. Annual inputs of ARGs from Adélie penguins on Inexpressible Island have increased since 1983. Bacitracin, multidrug, and aminoglycoside resistance genes were the main ARGs among water, soil, and penguin guano. Primary medium-risk ARGs associated with human pathogenic bacteria were multidrug resistance genes, and main low-risk ARGs associated with mobile genetic elements (MGEs) were aminoglycoside resistance genes. Antibiotic-resistant bacteria (ARB) from soil and penguins were more phylogenetically related to aquatic antibiotic-resistant mesophiles than aquatic antibiotic-resistant psychrophiles. MGEs, ARB, bacterial diversities, antibiotics, and metals could explain total ARGs between water and soil. Intracellular MGEs were the most significant in-situ driver of iARGs in water, reflecting that horizontal gene transfer could facilitate the spread of ARGs in water. Penguins were important ex-situ drivers of environmental antibiotic resistome, which was linked with risky ARGs between water and soil. These findings highlight the major roles of natural drivers (e.g., MGEs and penguins) in shaping environmental antibiotic resistome in polar areas, improving our understanding of the evolution of environmental microbiome.</div></div>","PeriodicalId":34602,"journal":{"name":"Fundamental Research","volume":"5 1","pages":"Pages 269-281"},"PeriodicalIF":6.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47034287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The eastern margin of the Tibetan plateau (TP) has been an important passageway for south‒north migration of agricultural groups since the late Neolithic. Prehistoric farmers began to occupy the northeastern Tibetan plateau (NETP) and the area of modern Yunnan Province (YNP), on the southeastern margin of the TP, from ∼5200 BP and ∼4600 BP, respectively. This occupation was potentially closely linked to climatic and environmental changes; however, the spatiotemporal pattern of moisture variations between these two regions, and its possible impact on human settlement and the migration of farming communities along the eastern margin of the TP during the late Neolithic and Bronze Age, are unclear. In the present study, well-dated sedimentary records with unambiguous indicators of humidity variations from the NETP and YNP were integrated, along with radiocarbon dates from human and animal bones and the remains of crop plants from archaeological sites in this region. The results indicate a long-term, out-of-phase relationship of moisture variations between the NETP and YNP during the middle to late Holocene. A mid-late Holocene increase in humidity on the NETP facilitated the development of agropastoral societies during the period of ∼5200‒2200 BP. However, pronounced cooling from ∼5000 BP forced the southward dispersal of millet farming groups along the eastern margin of the TP during the fifth millennium BP. Decreasing moisture in YNP promoted the expansion of an open landscape, which affected the development of agriculture during the period of ∼4600‒2200 BP. Our results suggest that changes in moisture affected the development of prehistoric agriculture in the northeastern and southeastern marginal areas of the TP in different ways, implying that the development of prehistoric human society largely depended on the regional climatic conditions.</div></div>","PeriodicalId":34602,"journal":{"name":"Fundamental Research","volume":"5 1","pages":"Pages 241-248"},"PeriodicalIF":6.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43215674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in-depth studies of the neural mechanisms of anesthetics are warranted. Hippocampal CA1 plays an important role during anesthesia. Currently, a high spatiotemporal resolution microdevice technology for the accurate detection of deep brain nuclei is lacking. In this research, four-shank 32-channel implantable microelectrode arrays (MEAs) were developed for the real-time recording of single-cell level neural information in rat hippocampal CA1. Platinum nanoparticles were modified onto the microelectrodes to substantially enhance the electrical properties of the microelectrode arrays. The modified MEAs exhibited low impedance (11.5 ± 1 kΩ) and small phase delay (-18.5° ± 2.54°), which enabled the MEAs to record single-cell level neural information with a high signal-to-noise ratio. The MEAs were implanted into the CA1 nuclei of the anesthetized rats, and the electrophysiological signals were recorded under different degrees of anesthesia mediated by low-dose concentrations of isoflurane. The recorded signals were analyzed in depth. Isoflurane caused an inhibition of spike firing rate in hippocampal CA1 neurons, while inducing low-frequency oscillations in CA1, thus enhancing the low-frequency power of local field potentials. In this manner, the spike firing rate and the power of local field potentials in CA1 could characterize the degree of isoflurane anesthesia.

It presents a novel artificial intelligence (AI) model for the diagnosis of cervical lesions through colposcopy images using a Dense-U-Net image semantic segmentation algorithm. The Dense-U-Net model was created by applying the methods of “deepening the network structure,” “applying dropout” and “max pooling.” Moreover, image-based and population-based diagnostic performances of the AI algorithm and physicians with different levels of specialist experience were compared.

The diagnostic accuracy of the Dense-U-Net model increased significantly with increasing colposcopy images per patient.
