Objective: To investigate the importance of hepcidin and paraoxonase in obstructive sleep apnea syndrome (OSAS).
Methods: Eighty-eight patients with sleep disorders were included and divided into four groups: simple snoring (SS), mild, moderate, and severe OSAS. All patients underwent polysomnography. The hepcidin and paraoxonase levels were examined and compared between the groups.
Results: There were significant differences between the four groups in terms of paraoxonase levels. In the SS group, the paraoxonase value was significantly higher than in the other three groups. In the analysis, Apnea Hypopnea Index (AHI) was negatively correlated with paraoxonase levels.
Conclusion: A significant difference was found between the OSAS groups with respect to paraoxonase enzyme, and a negative correlation with AHI was observed. Paraoxonase level could be used as a biomarker in OSAS. No significant data was found for hepcidin levels; therefore, hepcidin cannot be used as a biomarker in OSAS.
目的研究促血红素和副氧合酶在阻塞性睡眠呼吸暂停综合征（OSAS）中的重要性：方法：纳入 88 名睡眠障碍患者，将其分为四组：单纯性打鼾（SS）、轻度、中度和重度 OSAS。所有患者均接受了多导睡眠图检查。对各组患者的血红素和副氧酵素水平进行了检查和比较：结果：四组患者的副氧化酶水平存在明显差异。SS组的副氧化酶值明显高于其他三组。在分析中，呼吸暂停低通气指数（AHI）与副氧自由基酶水平呈负相关：结论：副氧自由基酶在 OSAS 各组间存在明显差异，且与 AHI 呈负相关。副氧合酶水平可作为 OSAS 的生物标志物。在血红素水平方面没有发现重要数据，因此血红素不能作为 OSAS 的生物标志物。

The lava tube in the Gruithuisen region on the Moon is intriguing because it is characterized by a distinctive chain of collapsed pits and raised features, providing an opportunity to understand the potential morphologic deformation of lunar lava tubes under compressional stress. This study aimed to understand the morphological deformation in the Gruithuisen region’s lava tube when subjected to compressional stress. A combination of numerical simulations and morphometric analysis was employed to achieve this objective. The morphometric analysis of different collapsed and raised features associated with a lava tube in the study area revealed eight characteristic morphologies ranging from curvilinear channel-like to elliptical shape. Notably, average normal stress and strain values derived from a wrinkle ridge were found to be ~70 MPa and 2 × 10−3, respectively, and wrinkle ridges exhibited a northward orientation. These quantified parameters were utilized as the foundation for initializing three-dimensional models. Furthermore, the outcomes of the models closely replicated the deformation in the Gruithuisen region, emphasizing the significant role of compressional stress in the deformation of the lava tube. These models suggest that the observed eight unique features associated with the lava tube arise from disparities in displacement magnitude and direction along three axes (x, y, z). Our research sheds light on the structural transformations of lava tubes when subjected to varying compressional stress and enhances understanding of the ways in which the interplay between compressional tectonic activity and lava tube features has shaped the Moon’s surface.

We present the first discovery of Late Paleozoic conodonts in Argentina, marking the southernmost occurrence of this fossil group in the dominantly cold, high latitudes of Gondwana. Recovered from the siliciclastic Río del Peñón (RDP) Formation at the Rincón Blanco section in the northern Precordillera, La Rioja Province, the fossil assemblage includes Neognathodus colombiensis and Neognathodus “pre-colombiensis,” precisely indicating the early Moscovian (late Atokan in North America) N. colombiensis Zone. Furthermore, the conodont fauna establishes a crucial temporal constraint for the brachiopod Tivertonia jachalensis–Streptorhynchus inaequiornatus (TS) Zone, which is a widely employed biostratigraphic unit in southern South America. The warm-water affinity of Neognathodus is in accordance with the record of typical paleoequatorial faunal elements in the TS Zone in several central western Argentinian basins, thus reinforcing the idea of a climatic amelioration in the southern latitudes of Gondwana during the early Moscovian.

Alluvial processes acting on scoria cones cause the development of a drainage network composed of radially distributed rills and gullies parallel to the volcanic edifice's downslope direction. We quantify the degree of drainage network development by applying the Average Erosion Index (AEI) method to scoria cones from the arid to semi-arid Lunar Crater volcanic field (Nevada, United States) and comparing our results with previously obtained results from two tropical volcanic fields (Sierra Chichinautzin volcanic field and the Parícutin-Tancítaro region, both in central Mexico). We show that the AEI method is useful in determining geomorphic age relations when calibrated separately for each field. Furthermore, the differences in AEI results for the three studied fields indicate that the method provides a way of quantifying the effects of different alluvial erosion rates at volcanic fields across various environments, including a delay in alluvial processes on cones in arid settings that has been qualitatively inferred by previous studies.

Global cooling with the onset of Antarctic glaciation ca. 34 Ma across the Eocene-Oligocene transition (EOT) terminated the early Cenozoic greenhouse climate state and marked the beginning of icehouse conditions. Although a pCO2 decline is considered to have been a major cause of this climate shift, the associated carbon-sequestration mechanism remains unclear. Here, we assessed ocean production and circulation changes across the EOT using numerical simulations combined with a novel proxy, namely, bacterial magnetofossils, the abundance and morphology of which are sensitive to sedimentary organic matter accumulation and oxygenation. We detected production and oxygenation declines in the equatorial Pacific Ocean coeval with increased biological production in the Southern Ocean after the EOT. Corroborated by simulation results and evidence from the Subantarctic region, we interpret this counterintuitive combination as a result of enhanced bottom-water formation and biological pump efficiency in the Southern Ocean due to Antarctic glacial buildup across the EOT. These results provide key evidence for deep Pacific Ocean deoxygenation and increased respired carbon concentrations, which amplified CO2 decline across the EOT.

Sediment transport in rivers is not steady through time. Highly intermittent river systems, which only transport bedload during the most significant flow events, are particularly sensitive to changes in climate and precipitation patterns. People and landscapes can be vulnerable to fluvial processes, and quantifying river intermittency is critical for assessing landscape response to projected changes in precipitation extremes due to climate change. We generated new constraints on recent to modern fluvial intermittency factors—the frequency at which bedload is mobilized in a river—based on field measurements in the Corinth Rift, Greece, and Holocene sediment accumulation rates. Results reveal some of the lowest documented intermittency factors to date, showing Mediterranean rivers can transport an entire annual sediment load in a rare storm event. Coupling intermittency calculations with historical flood and precipitation data indicates these rivers transport bedload during one storm every ~4 yr, associated with rainfall >50 mm/d, and subsequent floods; this hydroclimate is typical across the Mediterranean region. Furthermore, climate models predict precipitation extremes will increase across Europe, and the frequency of events that surpass thresholds of sediment transport will increase significantly, potentially causing sediment loads to double by 2100 CE. As the area of arid land likely to host intermittent rivers also increases, sensitive landscapes are on the edge of significant geomorphic change, driven by global warming.
