IntroductionThe Geostationary Ocean Color Imager-II (GOCI-II), launched on February 19, 2020, offers increased observation times throughout the day and higher spatial resolution compared to its predecessor, the Geostationary Ocean Color Imager (GOCI), launched in 2010. To ensure the reliability of GOCI-II data for practical applications, the accuracy of remote sensing products needs to be validated. This study uses in situ data from Lake Taihu for validation.MethodsWe assessed the accuracy of GOCI-II remote sensing products, including remote sensing reflectance derived using two atmospheric correction algorithms: ultraviolet (UV) and near-infrared (NIR). The study also evaluated the accuracy of derived parameters, such as chlorophyll-a (Chl-a) concentration, total suspended matter (TSM) concentration, and phytoplankton absorption coefficient (aph), based on these atmospheric correction algorithms. In situ measurements from Lake Taihu were used as ground truth data for validation.ResultsOur results revealed that the UV atmospheric correction algorithm provided higher accuracy in Lake Taihu compared to the NIR algorithm. The average absolute percentage deviations (APDs) for remote sensing reflectance across different bands were: 25.17% (412 nm), 29.69% (443 nm), 22.27% (490 nm), 19.38% (555 nm), 36.83% (660 nm), and 33.0% (680 nm). Compared to NIR-derived products, the UV algorithm showed improved accuracy for Chl-a concentration, TSM concentration, and aph, with reductions in APD values by 16.92%, 3.32%, and 10.91%, respectively. When applying UV correction, the 412 nm band performed better than the 380 nm band, likely due to a lower signal-to-noise ratio at 380 nm and smaller extrapolation errors at 412 nm.DiscussionWhile the NIR algorithm is suitable for open ocean waters, the UV algorithm demonstrated higher accuracy in turbid environments such as Lake Taihu. Therefore, a combined UV-NIR atmospheric correction algorithm may be more effective for handling various types of water environments. Additionally, further research is needed to develop more suitable retrieval algorithms for Chl-a concentration and aph in eutrophic waters to improve accuracy.

As one branch of deterministic approaches to disjoint bilinear programming, cutting plane methods are renowned for its ability to systematically reduce the search space by adding cutting planes that are able to cut off regions deemed infeasible or suboptimal. Polar cuts have been widely utilized as a dominating type of cut in terms of deepness. During the establishment of a polar cut, the modified Newton's method is employed to derive the cutting points along the positive or negative extensions of edges emanating from a local solution. Nonetheless, its performance can be further improved along the positive extensions. Drawing inspiration from integer programming, we develop a new approach based on the LP duality theory for this purpose. It re-formulates the original program with a piece-wise linear concave objective function as a single LP. Moreover, we propose a new technique to derive the edges as accommodation to degeneracy. Numerical results show that, by utilizing our newly developed dual method, computing time can be gradually saved as the percentage of generated cutting points along the positive extensions of edges rises.

Against the background of climate warming, marine heatwaves (MHWs) and terrestrial drought events have become increasingly frequent in recent decades. However, the combined effects of MHWs and terrestrial drought on CO2 uptake in marginal seas are still unclear. The East China Sea (ECS) experienced an intense and long-lasting MHW accompanied by an extreme terrestrial drought in the Changjiang basin in the summer of 2022. In this study, we employed multi-source satellite remote sensing products to reveal the patterns, magnitude, and potential drivers of CO2 flux changes in the ECS resulting from the compounding MHW and terrestrial drought extremes. The CO2 uptake of the ECS reduced by 17.0% (1.06 Tg C) in the latter half of 2022 and the Changjiang River plume region shifted from a CO2 sink to a source (releasing 0.11 Tg C) in July-September. In the majority of the ECS, the positive sea surface temperature (SST) anomaly during the MHW diminished the solubility of CO2 in seawater, thereby reducing CO2 uptake. Moreover, the reduction in nutrient input associated with terrestrial drought, which is unfavorable to phytoplankton growth, further reduced the capacity of CO2 uptake. Meanwhile, the CO2 sink doubled for the offshore waters of the ECS continental shelf in July-September 2022, indicating the complexity and heterogeneity of the impacts of extreme climatic events in marginal seas. This study is of great significance in improving the estimation results of CO2 fluxes in marginal seas and understanding sea–air CO2 exchanges against the background of global climate change.

Due to the hydrodynamic pressure effect, the bearing capacity of the oil film on the surface of a textured friction pair is greater than that of a smooth surface. In this paper, the effects of PTFE surface texture parameters (shape, depth, width, and area ratio) on the oil film bearing capacity and leakage of the sealing system under lubrication are studied using the FLURNT simulation. It is found in this present study that greater texture depths do not necessarily lead to better sealing performance. When the texture depth exceeds a certain level, a reverse flow occurs at the bottom of the texture, thereby weakening the hydrodynamic pressure effect. An optimal texture depth of 5–10 μm maximizes the oil film bearing capacity. Within a certain range, the oil film bearing capacity increases along with texture widths. In addition, leakage of the rectangular texture rises significantly with growing texture widths. Larger texture area ratios result in higher leakage, but the bearing capacity first rises and then falls with an increase in the area ratio, with a maximum value of 70–80%. Considering the influence of texture parameters on oil film bearing capacity and leakage, selecting the most appropriate texture parameters for surface texture treatment optimizes the performance of the sealing system. The findings of this paper provide a theoretical basis for improving the sealing performance of high-end aviation equipment using texture treatment, thereby enabling the application of surface texture technology to improve the tribological properties of materials.

Abstract Background Coronary chronic total occlusions (CTOs) are related to increased risk of adverse clinical outcomes. The optimal treatment strategy for CTO has not been well established. We sought to examine the impact of CTO percutaneous coronary intervention (PCI) on long-term clinical outcome in the real world. Methods A total of 592 patients with CTO were enrolled. 29 patients were excluded due to coronary artery bypass grafting (CABG). After exclusion, 563 patients were divided into the no-revascularized group (CTO-NR group, n = 263) and successful revascularized group (CTO-R group, n = 300). The primary endpoint was cardiac death; secondary endpoint was major adverse cardiac and cerebrovascular events (MACCE), a composite of all-cause death, cardiac death, recurrent myocardial infarction, target lesion revascularization, re-hospitalization, heart failure, and stroke. Results Percent of Diabetes mellitus (53.2% vs 39.7), Chronic kidney disease (8.7% vs 3.7%), CABG history (7.6% vs 1%), three vessel disease (96.2% vs 90%) and left main coronary artery disease (25.1% vs 13.7%) was significantly higher in the CTO-NR group than in success PCI group (all P

Polar-orbiting ocean color satellites can monitor daily to interannual variations in water transparency (or Secchi disk depth, SDD) from regional to global oceans. However, diurnal variations in SDD of coastal oceans remain poorly understood. Based on the bio-optical SDD algorithm, we retrieved the SDD products of hourly observations using the Geostationary Ocean Color Imager (GOCI) from 2011 to 2020 in the eastern China seas. The determination coefficient (R2) between the SDD product and the in situ dataset is 0.93, with a root mean squared error (RMSE) of 0.86 m. Based on the pixel-level tempo-spatial analysis, superpixel image segmentation retrieved by a simple linear iterative clustering algorithm (SLIC) was applied to classify the SDD product. The reconstruction SDD superpixel products not only match the spatial distribution well but can also more clearly express the spatial gradient. The percentage of the diurnal change in transparency was high in the nearshore (∼10 %), medium in transitional waters (∼5%), and low in offshore waters (∼3%). Finally, we found a significant negative correlation between SDD and wind speed (R2 = 0.65) and a significantly positive correlation between diurnal change range (DCR) and wind speed (R2 = 0.62). In contrast, sea surface temperature (SST) was positively correlated with SDD (R2 = 0.72) but significantly negatively correlated with DCR (R2 = 0.80). These results provide a basis for studying diurnal SDD changes in highly dynamic waters.

Abstract Background Triglyceride glucose (TyG) index is considered a reliable alternative marker of insulin resistance and an independent predictor of cardiovascular (CV) outcomes. However, the prognostic value of TyG index in patients with type 2 diabetes mellitus (T2DM) and acute myocardial infarction (AMI) remains unclear. Methods A total of 1932 consecutive patients with T2DM and AMI were enrolled in this study. Patients were divided into tertiles according to their TyG index levels. The incidence of major adverse cardiac and cerebral events (MACCEs) was recorded. The TyG index was calculated as the ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL)/2]. Results Competing risk regression revealed that the TyG index was positively associated with CV death [2.71(1.92 to 3.83), p

Abstract Background Differences in outcomes for women and men after percutaneous coronary intervention (PCI) in chronic total occlusion (CTO) patients remain controversial. Herein, we compared the clinical outcomes by sex in CTO patients undergoing PCI. Methods A total of 563 consecutive patients (19% women) who were diagnosed with CTO at a single center in China from June 2017 to December 2019 were included in this study. Three hundred patients were revascularized by PCI, and 263 were not revascularized. The clinical outcomes of these patients stratified by sex were examined. The primary endpoints included the risk of major adverse cardiovascular and cerebrovascular events (MACCE); the secondary endpoint was cardiac death; hazard ratios were generated using multivariable Cox regression. Results Women represented 19% of the cohort (107/563 patients). Women have lower mean body mass index (BMI) and abdominal circumference compared with men; however, the proportion of hypertension, diabetes, and previous coronary heart disease is higher in female patients. At 2-year follow-up, there were no differences between men and women for MACCE (15.8% vs 20.6%, p = 0.234) and cardiac death (3.1% vs 5.6%, p = 0.202). Predictors of CTO recanalization revealed that age < 65 years, absence of prior CABG, no history of DM, and non-triple vessel were predictors of CTO recanalization. Sex did not predict recanalization in this regression model. Successful CTO PCI was associated with reduced MACCE. Conclusion Our study suggests an equal benefit of CTO recanalization with a marked reduction in MACCE in women and men alike. Further dedicated studies are needed to confirm these findings.

AbstractBackground Daytime variation with regard to onset time of ST-elevation myocardial infarction (STEMI) symptoms has been observed. Nevertheless, with the advanced medical therapy, it is not uncertainty if a similar circadian pattern of STEMI symptom onset occurs, as well as its possible impact on clinical outcomes. Few long-term data are available. We assess the impact of circadian symptom-onset patterns of STEMI on major adverse cardiovascular events (MACE) in more contemporary patients treated with primary percutaneous coronary intervention (PPCI).Methods and results A total of 1099 consecutive STEMI patients undergoing PPCI ≤12h from symptom onset during 2013 to 2019 were classified into 4 groups by 6-h intervals according to time-of-day at symptom onset: night (0:00–5:59), morning (6:00–11:59), afternoon (12:00–17:59), and evening (18:00–23:59). Incidence of MACE including cardiovascular death and nonfatal MI during a median follow-up of 48 months was compared among the 4 groups. A morning peak of symptom onset of STEMI was detected during the period 06:00–11:59 (p

Aquaculture. Fisheries. Angling ,SH1-691 - Abstract
Accurate knowledge of species distributions and population dynamics is the basis for conservation biology. However, for certain species with unique life histories and very small populations, monitoring species distributions and population dynamics is extremely difficult. Recently, newly developed eDNA technology has been widely used in species monitoring, biodiversity assessments, and biomass assessments. In this research, we studied Fenneropenaeus chinensis in the Bohai Sea. We used a 0.45 μm glass fiber filter combined with a vacuum to filter 2 L seawater samples for eDNA enrichment from 54 stations in June and 60 stations in August. A DNeasy Blood and Tissue kit was used to extract the eDNA. After DNA extraction, the specific primers and probes of the mitochondrial DNA COI gene of F. chinensis were designed. Real-time quantitative PCR was used to qualitatively and quantitatively analyze the eDNA in the Bohai Sea. The temporal and spatial distribution of F. chinensis was detected by the eDNA technique. The relationship between the eDNA copy number and trawl-netted F. chinensis biomass was explored. The applicability and sensitivity of eDNA technology in marine crustacean research were verified. The results showed that the mtDNA COI gene of F. chinensis was successfully amplified in the 54 water samples collected in June, and the detection rate reached 100%. Detections occurred in only 23 of the 60 stations sampled in August. F. chinensis had a detection rate of only 38%. The copy number of eDNA obtained by real-time PCR was fitted to the density of F. chinensis captured by bottom trawling. There was not a significant positive correlation between copy number and biomass. The results obtained through this research will provide a method and theoretical basis for the application of eDNA technology in marine crustacean research.

Abstract Background Current guidelines recommend angiotensin-converting-enzyme inhibitors (ACEI)/angiotensin receptor blockers (ARB) as a first-line therapy in diabetic hypertensive patients and for secondary prevention in patients with obstructive coronary artery disease (OCAD). However, the effects of using ACEI/ARB before the initial diagnosis of OCAD on major adverse cardiac and cerebral event (MACCE) in diabetic hypertensive patients remain unclear. This study investigated whether using ACEI/ARB before the initial diagnosis of OCAD could be associated with improved clinical outcomes in diabetic hypertensive patients. Methods A total of 2501 patients with hypertension and diabetes, who were first diagnosed with OCAD by coronary angiography, were included in the analysis. Of the 2501 patients, 1300 did not used ACEI/ARB before the initial diagnosis of OCAD [the ACEI/ARB(-) group]; 1201 did [the ACEI/ARB(+) group]. Propensity score matching at 1:1 was performed to select 1050 patients from each group. Incidence of acute myocardial infarction (AMI), infarct size in patients with AMI, heart function, and subsequent MACCE during a median of 25.4-month follow-up were determined and compared between the 2 groups. Results Compared with the ACEI/ARB(-) group, the ACEI/ARB(+) group had significantly lower incidence of AMI (22.5% vs. 28.4%, p

Background. The effects of β-blockers in patients with unstable angina pectoris (UAP) are unclear. We tried to evaluate associations between β-blockers in UAP and long-term outcomes. Methods. We enrolled 5591 UAP patients and divided them into 2 groups based on β-blockers at discharge: 3790 did β-blockers and 1801 did not used them. Propensity score matching at 1 : 1 was performed to select 1786 patients from each group. The primary endpoint was major adverse cardiac and cerebral events (MACCE) during the long-term follow-up period. Results. 67.8% of patients were on β-blockers at discharge; these patients were more likely to have CHD risk factors, lower ejection fraction, and severity of the coronary artery lesions. Over a median of 25.0 years, the incidence of MACCE was 25.5%. The risk was not significantly different between those on and those not on β-blocker treatment. The multivariate Cox regression analysis showed that no β-blocker use at discharge was not an independent risk factor for MACCE and sequence secondary endpoints. After propensity score matching, the results were similar. Conclusions. β-blocker use was not associated with lower MACCE and other secondary composite endpoints in long-term outcomes. This result adds to the increasing body of evidence that the routine prescription of β-blockers might not be indicated in patients with UAP. Trial registration had retrospectively registered.

Abstract Background Current guidelines recommend angiotensin-converting-enzyme inhibitors (ACEI) or angiotensin-receptor blockers (ARB) or β-blockers (β-B) for secondary prevention in patients after an acute myocardial infarction (AMI). However, there is limited data to evaluate ACEI/ARB/β-B (AAβ) used before AMI on major adverse cardiovascular events (MACE), in China patients. Objectives This study sought to investigate whether AAβ treatment prior to AMI is associated with better hospital outcomes at the onset of AMI. Methods A total of 2705 patients were selected from the Cardiovascular Center Beijing Friendship Hospital Database Bank, and divided into two groups on the basis of admission prescription: AAβ (n = 872) or no-AAβ (n = 1833). The study was also designed using propensity-score matching (226 AAβ treated patients vs 452 no-AAβ treated patients). The primary outcome was a composite of cardiac death and heart function and infarct size during hospitalization follow-up. Results The mean follow-up period was about 8 days in MACE. The Cox model showed the two groups had similar risk of cardiac death. The in-hospital mortality was 3.36% (3.33% of AAβ users and 3.38% of nonusers, p = 0.94). In adjusted analysis, there was still no difference in in-hospital mortality between the two groups (3.54% vs 2.88%, p = 0.64). However, the AAβ treated patients were associated with better heart function and smaller infarct size than the no-AAβ treated patients. Conclusions The in-hospital MACE was similar between AAβ treated patients and no-AAβ treated patients. However, treatment with AAβ before AMI was associated with improved heart function and smaller infarct size.

Validation of remote-sensing reflectance (Rrs) products is necessary for the quantitative application of ocean color satellite data. While validation of Rrs products has been performed in low to moderate turbidity waters, their performance in highly turbid water remains poorly known. Here, we used in situ Rrs data from Hangzhou Bay (HZB), one of the world’s most turbid estuaries, to evaluate agency-distributed Rrs products for multiple ocean color sensors, including the Geostationary Ocean Color Imager (GOCI), Chinese Ocean Color and Temperature Scanner aboard HaiYang-1C (COCTS/HY1C), Ocean and Land Color Instrument aboard Sentinel-3A and Sentinel-3B, respectively (OLCI/S3A and OLCI/S3B), Second-Generation Global Imager aboard Global Change Observation Mission-Climate (SGLI/GCOM-C), and Visible Infrared Imaging Radiometer Suite aboard the Suomi National Polar-orbiting Partnership satellite (VIIRS/SNPP). Results showed that GOCI and SGLI/GCOM-C had almost no effective Rrs products in the HZB. Among the others four sensors (COCTS/HY1C, OLCI/S3A, OLCI/S3B, and VIIRS/SNPP), VIIRS/SNPP obtained the largest correlation coefficient (R) with a value of 0.7, while OLCI/S3A obtained the best mean percentage differences (PD) with a value of −13.30%. The average absolute percentage difference (APD) values of the four remote sensors are close, all around 45%. In situ Rrs data from the AERONET-OC ARIAKE site were also used to evaluate the satellite-derived Rrs products in moderately turbid coastal water for comparison. Compared with the validation results at HZB, the performances of Rrs from GOCI, OLCI/S3A, OLCI/S3B, and VIIRS/SNPP were much better at the ARIAKE site with the smallest R (0.77) and largest APD (35.38%) for GOCI, and the worst PD for these four sensors was only −13.15%, indicating that the satellite-retrieved Rrs exhibited better performance. In contrast, Rrs from COCTS/HY1C and SGLI/GCOM-C at ARIAKE site was still significantly underestimated, and the R values of the two satellites were not greater than 0.7, and the APD values were greater than 50%. Therefore, the performance of satellite Rrs products degrades significantly in highly turbid waters and needs to be improved for further retrieval of ocean color components.

Introduction:The predictive value of soluble suppression of tumorigenicity 2 (sST2) for the occurrence of major adverse cardiovascular events (MACEs) in patients with ST‑segment elevation myocardial infarction (STEMI) remains unclear.We aimed to investigate the role of sST2 in predicting MACEs in STEMI patients after primary percutaneous coronary intervention (pPCI).A total of 350 patients were enrolled in this study. The levels of sST2, N‑terminal pro-B‑type natriuretic peptide (NT‑proBNP), cardiac troponin I (TnI), and creatine kinase-MB (CK‑MB) were measured on admission as well as 24 hours and 5 days after pPCI. The end point was the incidence of MACEs.Compared with the values on admission, sST2 levels increased 24 hours post pPCI and decreased significantly at day 5 after the procedure in the whole cohort. The pattern of sST2 level changes between the 3 time points was similar in the MACE and MACE‑free groups. Notably, the change in the sST2 level from admission to 24 hours post pPCI (Δ1sST2) was significantly higher in the MACE group. After multivariable adjustment, Δ1sST2 was an independent risk factor for MACEs, with an area under the curve of 0.621 (95% CI, 0.547-0.695). Patients with a greater Δ1sST2 had a significantly higher incidence of composite MACEs, coronary revascularization, and cardiac rehospitalization. However, the change in sST2 levels from admission to 5 days post pPCI, as well as the dynamic changes in NT‑proBNP, TnI, and CK‑MB levels had no predictive value.The increase in plasma sST2 levels from admission to 24 hours post pPCI has a potential value for independently predicting the incidence of coronary revascularization and cardiac rehospitalization at 1 year in patients with STEMI.

Background Daytime variation with regard to onset time of ST-elevation myocardial infarction (STEMI) symptoms has been observed. Nevertheless, with the advanced medical therapy, it is not uncertainty if a similar circadian pattern of STEMI symptom onset occurs, as well as its possible impact on clinical outcomes. Few long-term data are available. We assess the impact of circadian symptom-onset patterns of STEMI on major adverse cardiovascular events (MACE) in more contemporary patients treated with primary percutaneous coronary intervention (PPCI). Methods and results A total of 1099 consecutive STEMI patients undergoing PPCI ≤12h from symptom onset during 2013 to 2019 were classified into 4 groups by 6-h intervals according to time-of-day at symptom onset: night (0:00–5:59), morning (6:00–11:59), afternoon (12:00–17:59), and evening (18:00–23:59). Incidence of MACE including cardiovascular death and nonfatal MI during a median follow-up of 48 months was compared among the 4 groups. A morning peak of symptom onset of STEMI was detected during the period 06:00–11:59 (p

Long non‑coding RNAs (lncRNAs) have emerged as key players in the development and progression of cancer. FEZ family zinc finger 1 antisense RNA 1 (FEZF1‑AS1) is a novel lncRNA that is involved in the development of cancer and acts as a potential biomarker for cancer. However, the clinical significance and molecular mechanism of FEZF1‑AS1 in non‑small cell lung cancer (NSCLC) remains uncertain. In the present study, FEZF1‑AS1 was selected using Arraystar Human lncRNA microarray and was identified to be upregulated in NSCLC tissues and negatively associated with the overall survival of patients with NSCLC. Loss‑of‑function assays revealed that FEZF1‑AS1 inhibition decreased cell proliferation and migration, and arrested cells at the G2/M cell cycle phase. Mechanistically, FEZF1‑AS1 expression was influenced by N6‑methyladenosine (m6A) modification. Since FEZF1‑AS1 was mainly located in the cytoplasmic fraction of NSCLC cells, it was hypothesized that it may be involved in competing endogenous RNA regulatory network to impact the prognosis of NSCLC. Via integrating Arraystar Human mRNA microarray data and miRNA bioinformatics analysis, it was revealed that ITGA11 expression was decreased with loss of FEZF1‑AS1 and increased with gain of FEZF1‑AS1 expression, and microRNA (miR)‑516b‑5p inhibited the expression levels of both FEZF1‑AS and ITGA11. RNA‑binding protein immunoprecipitation and RNA pulldown assays further demonstrated that FEZF1‑AS1 could bind to miR‑516b‑5p and that ITGA11 was a direct target of miR‑516b‑5p by luciferase reporter assay. Overall, the present findings demonstrated that FEZF1‑AS1 was upregulated and acted as an oncogene in NSCLC by regulating the ITGA11/miR‑516b‑5p axis, suggesting that FEZF1‑AS1 may be a potential prognostic biomarker and therapeutic target for NSCLC.

Increased body mass index (BMI) is a well-established risk factor for cardiovascular disease; however, patients with elevated BMI, in comparison to those with low BMI, seem to have better survival, a phenomenon reported as "obesity paradox," which remains controversial. We investigated the effect of BMI on cardiac mortality post acute myocardial infarction (AMI).In this analysis, 3562 AMI patients were included and classified into four groups based on BMI values. The primary endpoint was cardiac death. Compared to normoweight group, overweight and obese group subjects were younger, mostly men, and more likely to receive percutaneous coronary intervention (PCI) and had higher levels of glucose and lipids, but lower level of NTproBNP. Subjects in the underweight group were older, were mostly women, had lower Barthel index (BI), were less likely to receive PCI, and had lower levels of glucose and lipids, but higher level of N-terminal pro-brain natriuretic peptide (NTproBNP) and higher rates of left ventricular ejection fraction (LVEF) < 50%. During a median follow-up period of 1.9 years, cardiac death occurred significantly more in the underweight group (30.0%, 10.6%, 7.0%, and 5.0% among the four groups from underweight to obese; P < 0.001 for trend). The Cox analysis revealed that underweight was an independent predictor of subsequent cardiac death (odds ratio (OR), 1.86; 95% confidence interval (CI), 1.07-3.25) and identified that older age, BI < 60, higher levels of cardiac troponin I (cTnI), LVEF < 50%, and not receiving PCI were independently associated with increased risk of cardiac death.Patients who were underweight were at greater risk of cardiac death post AMI. In addition, older age, frail, higher levels of cTnI, LVEF < 50%, and not receiving PCI also independently predicted cardiac mortality post AMI.

Accurate knowledge of species distributions and population dynamics is the basis for conservation biology. However, for certain species with unique life histories and very small populations, monitoring species distributions and population dynamics is extremely difficult. Recently, newly developed eDNA technology has been widely used in species monitoring, biodiversity assessments, and biomass assessments. In this research, we studied Fenneropenaeus chinensis in the Bohai Sea. We used a 0.45 μm glass fiber filter combined with a vacuum to filter 2 L seawater samples for eDNA enrichment from 54 stations in June and 60 stations in August. A DNeasy Blood and Tissue kit was used to extract the eDNA. After DNA extraction, the specific primers and probes of the mitochondrial DNA COI gene of F. chinensis were designed. Real-time quantitative PCR was used to qualitatively and quantitatively analyze the eDNA in the Bohai Sea. The temporal and spatial distribution of F. chinensis was detected by the eDNA technique. The relationship between the eDNA copy number and trawl-netted F. chinensis biomass was explored. The applicability and sensitivity of eDNA technology in marine crustacean research were verified. The results showed that the mtDNA COI gene of F. chinensis was successfully amplified in the 54 water samples collected in June, and the detection rate reached 100%. Detections occurred in only 23 of the 60 stations sampled in August. F. chinensis had a detection rate of only 38%. The copy number of eDNA obtained by real-time PCR was fitted to the density of F. chinensis captured by bottom trawling. There was not a significant positive correlation between copy number and biomass. The results obtained through this research will provide a method and theoretical basis for the application of eDNA technology in marine crustacean research.

Diurnal monitoring of the Secchi-disk depth (SDD) of eutrophic lakes is the basic requirement to ensure domestic, industrial, and agricultural water use in surrounding cities. The retrieval of SDD in high frequency and longer observation period is the basic monitoring requirement to guarantee water environmental quality. Taking Lake Taihu as an example, the diurnal high-frequency observation (10 mins) data of the geostationary meteorological satellite sensor AHI/Himawari-8 were examined in this study. The results showed that the AHI normalized water-leaving radiance (Lwn) product derived by the Shortwave-infrared atmospheric correction (SWIR-AC) algorithm was consistent with the in situ data, with determination coefficient (R2) all larger than 0.86 and the mean absolute percentage deviation (MAPD) of 19.76%, 12.83%, 19.03% and 36.46% for the 460 nm, 510 nm, 640 nm and 860 nm bands, respectively. 510 nm and 640 nm bands showed more better consistency with in situ data in Lake Taihu. Therefore, an empirical SDD algorithm was established based on the AHI green (510 nm) and red (640 nm) bands. The SDD algorithm was verified by in situ data showed good performance with R2 of 0.81, RMSE of 5.91 cm, and MAPD of 20.67%. Based on the AHI data and established algorithm, diurnal high-frequency variation of the SDD in the Lake Taihu was investigated and the environmental factor (wind speed, turbidity degree, and photosynthetically active radiance) corresponding to diurnal SDD variation were discussed. This study should be helpful for studying diurnal high-dynamics physical-biogeochemical processes in eutrophication lake waters.

This study sought to characterize the relationship between body mass index (BMI) and the risk of new-onset atrial fibrillation (NOAF).Methods: A total of 4282 participants free from AF at baseline were identified at Beijing Friendship Hospital. Baseline body mass index (BMI) was categorized into four groups. Incidence of NOAF was observed at the follow-up visits. The associations between different BMI categories and the incidence of NOAF were assessed by multivariate Cox regression analysis.Results: Over a median follow-up period of 42.0 months, 4282 participants (age 62.7 ± 6.6 years, 38.7% women) were enrolled, 23.0% were BMI < 23.0kg/m2, 22.5% were 23.0â 24.9 kg/m2, 44.3% were 25.0â 29.9 kg/m2 and 10.2% were ⥠30.0 kg/m2. Compared with patients with the lowest BMI levels, those with BMI⥠30 kg/m2 showed a younger, higher inflammatory response and a larger left atrium and were more likely to be combined with traditional cardiovascular risk factors. After adjustment for confounding variables, compared to BMI ⥠30 kg/m2 group, patients with lower BMI (< 23 kg/m2) significantly increased the risk of NOAF in AMI patients (HR 2.884, 95% CI 1.302â 6.392). Moreover, the all-cause mortality and cardiac mortality in BMI < 23.0kg/m2 group was apparently higher than that in BMI⥠30 kg/m2 group after a long-term follow-up.Conclusion: In this AMI cohort study, the present finding of an inverse association between BMI and risk of NOAF supports the âobesity paradoxâ. Decreasing BMI was associated with an increased risk of NOAF.Trial Registration: Prospective registered.Keywords: atrial fibrillation, acute myocardial infarction, body mass index, obesity

Photosynthetically available radiation (PAR) is essential for the photosynthesis processes of land plants and aquatic phytoplankton. Satellite observation with different diurnal frequencies (e.g., high frequency from geostationary satellites and low frequency from polar-orbit satellites) provides a unique technique to monitor PAR variation on large tempo-spatial scales. Owing to different climatic characteristics, different regions may require different observation frequencies to obtain accurate PAR estimation, but such requirements are still poorly known. Here, based on Advanced Himawari Imager (AHI) high-frequency (10-min) observation data from the geostationary satellite Himawari-8, we investigated the influence of diurnal observation frequency on the accuracy of PAR estimation and provided the minimal observing frequency to get high accurate PAR estimation in the AHI coverage area. Our results revealed a remarkable difference in the requirements for the diurnal observation frequency in both spatial and temporal distributions. Overall, high-latitude regions need a higher observing frequency than low-latitude areas, and winter half-years need higher observing frequency than summer half-years. These results provide a basis for designing satellites to accurately remote sensing of PAR in different regions.

Objective Strict control measures under the COVID epidemic have brought an inevitable impact on ST-segment elevation myocardial infarction (STEMI)’s emergency treatment. We investigated the impact of the COVID on the treatment of patients with STEMI undergoing primary PCI. Methods In this single center cohort study, we selected a time frame of 6 month after declaration of COVID-19 infection (Jan 24-July 24, 2020); a group of STEMI patients in the same period of 2019 was used as control. Finally, a total of 246 STEMI patients, who were underwent primary PCI, were enrolled into the study (136 non COVID-19 outbreak periods and 110 COVID-19 outbreak periods). The impact of COVID on the time of symptom onset to the first medical contact (symptom-to-FMC) and door to balloon (D-to-B) was investigated. Moreover, the primary outcome was in-hospital major adverse cardiac events (MACE), defined as a composite of cardiac death, heart failure and malignant arrhythmia. Results Compared with the same period in 2019, there was a 19% decrease in the total number of STEMI patients undergoing primary PCI at the peak of the pandemic in 2020. The delay in symptom-to-FMC was significantly longer in COVID Outbreak period (180 [68.75, 342] vs 120 [60,240] min, P = 0.003), and the D-to-B times increased significantly (148 [115–190] vs 84 [70–120] min, P < 0.001). However, among patients with STEMI, MACE was similar in both time periods (18.3% vs 25.7%, p = 0.168). On multivariable analysis, COVID was not independently associated with MACE; the history of diabetes, left main disease and age>65 years were the strongest predictors of MACE in the overall population. Conclusions The COVID pandemic was not independently associated with MACE; suggesting that active primary PCI treatment preserved high-quality standards even when challenged by a severe epidemic.

Background Neutrophil and albumin are respective indicators of inflammation and malnutrition. Whether combining those 2 markers can predict acute prognosis in patients with ST-segment elevation myocardial infarction (STEMI) remains unknown. This study aimed to investigate the prognostic value of neutrophil percentage to albumin ratio (NPAR) for in-hospital mortality in STEMI patients. Material/Methods There were 1024 patients hospitalized with acute STEMI retrospectively enrolled in this study. Demographic, clinical, and admission laboratory data were extracted from medical record. NPAR was calculated as neutrophil percentage numerator divided by albumin in the admission blood samples. In-hospital mortality was designed as the primary outcome in the study, major adverse cardiac events (MACE) and cardiac death were recorded as the secondary clinical outcomes. Results The rates of in-hospital mortality, MACE, and cardiac death in high NPAR group were significantly higher than those in the low NPAR group (P1.9 was identified as an effective cut point in STEMI for in-hospital mortality (P

This study investigated whether a novel index of stress hyperglycemia might have a better prognostic value compared to admission glycemia alone in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). The acute-to-chronic glycemic ratio was expressed as admission blood glucose (ABG) devided by the estimated average glucose (eAG), and eAG was derived from the glycated hemoglobin (HbA1c). A total of 1300 consecutive patients with STEMI treated with PCI were included. Baseline data and outcomes were analyzed. The study end point was a composite of in-hospital all-cause death, cardiogenic shock, and acute pulmonary edema. Accuracy was defined with area under the curve (AUC) by a receiver–operating characteristic (ROC) curve analysis. After multivariate adjustment, both ABG/eAG and ABG were closely associated with an increased risk of the composite end point in nondiabetic patients. However, only ABG/eAG (odds ratio = 2.45, 95% confidence interval: 1.24-4.82, P = .010), instead of ABG, was associated with the outcomes in diabetic patients. Compared to ABG, ABG/eAG had an equivalent predictive value in nondiabetic patients but a superior discriminatory ability in diabetic patients (AUC improved from 0.52-0.63, P < .001). Taken together, ABG/eAG provides more significant in-hospital prognostic information than ABG in diabetic patients with STEMI after PCI.

The prognostic value of the CHA2DS2-VASc score in acute coronary syndrome (ACS) patients without atrial fibrillation (AF) who underwent percutaneous coronary intervention remains uncertain. We examine the association of the CHA2DS2-VASc score and major adverse cardiovascular events (MACE) in this population and compared its risk prediction with 2 other commonly used risk scores (Global Registry of Acute Coronary Events [GRACE] and thrombolysis in myocardial infarction [TIMI]). A total of 3,745 consecutive ACS patients without AF who underwent percutaneous coronary intervention during 2013 to 2017 were classified into 4 groups according to the CHA2DS2-VASc score: low (0 to 1), moderate (2 to 3), high (4 to 5), and very high (>5). Incidences of MACE including cardiovascular death, nonfatal myocardial infarction, or stroke in-hospital and during a median follow-up of 33 months were compared among the 4 groups. Receiver-operating characteristic curves were generated to compare CHA2DS2-VASc with GRACE and TIMI for risk prediction. The incidences of in-hospital MACE (3.5%, 6.6%, 7.6%, and 9.1%, p

The marginal semi-enclosed Bohai Sea is an important ecosystem for many commercial as well as ecologically important species. At the same time, the Bohai Sea increasingly facing various anthropogenic disturbances which have been reported to affect the functioning of this ecosystem in many ways. Using Ecopath and Ecosim modeling suite (ver 6.5), this study examined the temporal changes in the ecological status of the Bohai Sea ecosystem. The present model comprises a total of 23 functional groups based on a year-round trawl survey conducted in 2016. The results of the present study showed that the mean trophic level of the commercial species as well as the overall fisheries species declined during the last few decades. The fundamental source of biomass flows within the Bohai Sea food web generated from the lower trophic levels. Primary producers (phytoplankton) and detritus contributed about 52.77% and 47.23%, respectively of the total energy flows originated from the base of the food web in 2016. Estimation of the ecological parameters during the decadal-scale suggests that the Bohai Sea ecosystem is at an immature stage. The niche overlap indices showed intermediate overlaps between prey species rather than predator species overlapping. The mixed trophic impacts indicated that the lower trophic levels had positive influences on most of the groups in the higher trophic levels, indicating the strong bottom-up ecosystem dynamics. Increased biomass of jellyfish and cephalopod had moderate adverse effects on other groups. This comparative analysis provides an important platform by increasing our understanding of the several food web properties that can be integrated within a future management plan of the Bohai Sea fisheries resources.

AIM To evaluate the prognostic value of triglyceride-glucose (TyG) index in nondiabetic patients with acute coronary syndrome (ACS) with low-density lipoprotein cholesterol (LDL-C) below 1.8 mmol/L. METHODS A total of 1655 nondiabetic patients with ACS with LDL-C below 1.8 mmol/L were included in the analysis. Patients were stratified into two groups. The incidence of acute myocardial infarction (AMI), infarct size in patients with AMI, and major adverse cardiac and cerebral event during a median of 35.6-month follow-up were determined and compared between the two groups. The TyG index was calculated using the following formula: ln [fasting triglycerides (mg/dL)×fasting plasma glucose (mg/dL)/2]. RESULTS Compared with the TyG index <8.33 group, the TyG index ≥ 8.33 group had a significantly higher incidence of AMI (21.2% vs. 15.2%, p=0.014) and larger infarct size in patients with AMI [the peak value of troponin I: 10.4 vs. 4.8 ng/ml, p=0.003; the peak value of Creatine kinase MB: 52.8 vs. 22.0 ng/ml, p=0.006; the peak value of myoglobin: 73.7 vs. 46.0 ng/ml, p=0.038]. Although there was no significant difference in mortality between the two groups, the incidence of revascularization of the TyG index ≥ 8.33 group was significantly higher than that of the TyG index <8.33 group (8.9% vs. 5.0%, p=0.035). A multivariable Cox regression revealed that the TyG index was positively associated with revascularization [hazard ratio, 1.67; 95% confidence interval, 1.02-2.75; p=0.043]. CONCLUSIONS In nondiabetic patients with ACS with LDL-C below 1.8 mmol/L, a high TyG index level was associated with higher incidence of AMI, larger infarct size, and higher incidence of revascularization. A high TyG index level might be a valid predictor of subsequent revascularization.

BACKGROUND Alpha1-microglobulin (A1MG) is a small molecular protein related to oxidation and inflammation. It exists in diverse body fluids, including urine. Results from urine tests are sometimes neglected when predicting in-hospital prognosis. It remains unclear whether urinary A1MG (UA1MG) can predict short-term prognosis of ST-elevated myocardial infarction (STEMI). MATERIAL AND METHODS A total of 1854 hospitalized patients with acute STEMI were retrospectively enrolled in our study. Medical records were used to obtain patient demographic and clinical information, UA1MG values (which were used to divide patients into groups of low, medium, or high), and other laboratory parameters. Principal clinical outcomes of interest were all-cause in-hospital deaths, cardiac deaths, and major adverse cardiac events (MACEs). RESULTS Among the 1854 enrolled patients, 43 (2.3%) died in the hospital, of which 33 (1.8%) were cardiac deaths. MACEs were noted in 113 patients (6.1%) during hospitalization. The group with the highest UA1MG value showed a significantly higher frequency of in-hospital deaths, cardiac deaths, and MACEs, compared to those of the lowest UA1MG value group (4.4% vs. 1.0%, P

Background Triglyceride glucose (TyG) index is considered a reliable alternative marker of insulin resistance and an independent predictor of cardiovascular (CV) outcomes. However, the prognostic value of TyG index in patients with type 2 diabetes mellitus (T2DM) and acute myocardial infarction (AMI) remains unclear. Methods A total of 1932 consecutive patients with T2DM and AMI were enrolled in this study. Patients were divided into tertiles according to their TyG index levels. The incidence of major adverse cardiac and cerebral events (MACCEs) was recorded. The TyG index was calculated as the ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL)/2]. Results Competing risk regression revealed that the TyG index was positively associated with CV death [2.71(1.92 to 3.83), p p = 0.001], cardiac rehospitalization [2.42(1.81 to 3.24), p p p p p Conclusions The TyG index was significantly associated with MACCEs, suggesting that the TyG index may be a valid marker for risk stratification and prognosis in patients with T2DM and AMI.

Background Coronary chronic total occlusions (CTOs) are related to increased risk of adverse clinical outcomes. The optimal treatment strategy for CTO has not been well established. We sought to examine the impact of CTO percutaneous coronary intervention (PCI) on long-term clinical outcome in the real world. Methods A total of 592 patients with CTO were enrolled. 29 patients were excluded due to coronary artery bypass grafting (CABG). After exclusion, 563 patients were divided into the no-revascularized group (CTO-NR group, n = 263) and successful revascularized group (CTO-R group, n = 300). The primary endpoint was cardiac death; secondary endpoint was major adverse cardiac and cerebrovascular events (MACCE), a composite of all-cause death, cardiac death, recurrent myocardial infarction, target lesion revascularization, re-hospitalization, heart failure, and stroke. Results Percent of Diabetes mellitus (53.2% vs 39.7), Chronic kidney disease (8.7% vs 3.7%), CABG history (7.6% vs 1%), three vessel disease (96.2% vs 90%) and left main coronary artery disease (25.1% vs 13.7%) was significantly higher in the CTO-NR group than in success PCI group (all P p = 0.001) and fraction shortening (FS) (0.31 ± 0.07 vs 0.33 ± 0.07, p = 0.002). At a median follow-up of 12 months, CTO revascularization was superior to CTO no-revascularization in terms of cardiac death (adjusted hazard ratio [HR]: 0.27, 95% conference interval [CI] 0.11–0.64). The superiority of CTO revascularization was consistent for MACCE (HR: 0.55, 95% CI 0.35–0.79). At multivariable Cox hazards regression analysis, CTO revascularization remains one of the independent predictors of lower risk of cardiac death and MACCE. Conclusions Successful revascularization by PCI may bring more clinical benefits. The presence of low left ventricular ejection fraction (LVEF) and LM-disease was associated with an incidence of cardiac death; CTO revascularization was a protected predictor of cardiac death. Graphical abstract Successful revascularization by PCI offered CTO patients more clinical benefits, manifested by lower incidence of cardiac death during follow-up. The presence of LVEF

Background: To evaluate the prognostic value of triglyceride glucose (TyG) index in non-diabetic acute coronary syndrome (ACS) patients with low-density lipoprotein cholesterol (LDL-C) below 1.8mmol/L.Methods: A total of 1655 non-diabetic ACS patients with LDL-C below 1.8mmol/L were included in the analysis. Patients were stratified into 2 groups. Incidence of acute myocardial infarction (AMI), infarct size in patients with AMI, and major adverse cardiac and cerebral event (MACCE) during a median of 35.6-month follow-up were determined and compared between the 2 groups. The TyG index was calculated using the following formula: ln [fasting triglycerides (mg/dL) ×fasting plasma glucose (mg/dL)/2].Results: Compared with the TyG index p =0.014) and larger infarct size in patients with AMI (pTNI: 10.4 vs. 4.8 ng/ml, p =0.003; pCKMB: 52.8 vs. 22.0 ng/ml, p =0.006; pMyo: 73.7 vs. 46.0 ng/ml, p =0.038). Although there was no significant difference in mortality between the 2 groups, the incidence of revascularization of TyG index ≥8.33 group was significantly higher than that of TyG index p =0.035). Multivariable Cox regression revealed that the TyG index was positively associated with revascularization [HR (95% CI): 1.67 (1.02,2.75), p=0.043].Conclusion: In non-diabetic ACS patients with LDL-C below 1.8mmol/L, the high TyG index level was associated with higher incidence of AMI, larger infarct size, and higher incidence of revascularization. The high TyG index level might be a valid predictor of subsequent revascularization.Trial registration: retrospectively registered.

Although several classes of cutting plane methods for deterministically solving disjoint bilinear programming (DBLP) have been proposed, the frequently encountered computational issue regarding the generation of a suitable cut from a degenerate vertex in a pseudo-global minimizer (PGM) still remains. Among the approaches to dealing with degeneracy, the most recent one is to generate a conservative cut. Nevertheless, the computational performance of the corresponding distance-following algorithm for its location seems far from satisfactory. This paper proposes several approaches that can be utilized to efficiently locate a conservative hyperplane from a degenerate vertex in a PGM. Extensive experiments are conducted to evaluate their performance from the dimensionality as well as the degree of degeneracy. From the computational viewpoint, these new approaches can outperform the earlier developed distance-following algorithm, and thereby can be incorporated into cutting plane methods for solving DBLP.

Background Triglyceride glucose (TyG) index is considered a new marker for metabolic disorders. Although recent studies have found an association between TyG index level and vascular disease development, the prognostic value of TyG index in patients with acute myocardial infarction (AMI) remains unclear. Methods A total of 3181 patients with AMI, who underwent coronary angiography, were identified from the Cardiovascular Center of Beijing Friendship Hospital Database Bank and included in the analysis. Patients were stratified into 2 groups according to their baseline TyG index levels: the TyG index 2, smoker, diabetes mellitus, estimated glomerular filtration rate (eGFR) ≥ 60 ml/min/1.73 m2, high-density lipoprotein cholesterol ≥ 1.01 mmol/L and left ventricular ejection fraction (LVEF) ≥ 0.50. The results also revealed that diabetes mellitus, previous AMI, eGFR, LVEF, and multi-vessel/left main coronary artery lesions were independent predictors of MACEs in patients with AMI (all P

We aimed to develop a miRNA-based prediction model for differentiating SCC from AC in surgical resected tissues and bronchoalveolar lavage (BAL) samples. Expression levels of seven histological subtype-associated miRNAs were determined in 128 snap-frozen surgical lung tumor specimens by using reverse transcription-polymerase chain reaction (RT-PCR) to develop an optimal panel of miRNAs for acutely distinguishing SCC from AC. The biomarkers were validated in an independent cohort of 112 FFPE lung tumor tissues, and a cohort of 127 BAL specimens by using droplet digital PCR for differentiating SCC from AC. A prediction model with two miRNAs (miRs-205-5p and 944) was developed that had 0.988 area under the curve (AUC) with 96.55% sensitivity and 96.43% specificity for differentiating SCC from AC in frozen tissues, and 0.997 AUC with 96.43% sensitivity and 96.43% specificity in FFPE specimens. The diagnostic performance of the prediction model was reproducibly validated in BAL specimens for distinguishing SCC from AC with a higher accuracy compared with cytology (95.69 vs. 68.10%; P < 0.05). The prediction model might have a clinical value for accurately discriminating SCC from AC in both surgical lung tumor tissues and liquid cytological specimens.

Supplemental Digital Content is available in the text., Background: This study investigated whether the age, creatinine, and ejection fraction (ACEF) score [age (years) /ejection fraction (%) +1 (if creatinine>176μmol/L)] could predict 1-year outcomes following ST-segment elevation myocardial infarction after percutaneous coronary intervention, and whether accuracy could be improved by establishing novel ACEF-derived risk models. Methods: A total of 1146 patients were included. The study endpoint was 1-year major adverse cardio-cerebrovascular events, including all-cause death, nonfatal myocardial infarction, unplanned revascularization, and nonfatal stroke. Accuracy was defined with area under the curve by receiver-operating characteristic curve analysis. Results: The incidence of 1-year major adverse cardio-cerebrovascular event increased with the rising age, creatinine, and ejection fraction score tertiles (4.8%, 8.4%, and 15.2%, P < 0.001 for all). Higher ACEF score was significantly associated with an increased risk of the endpoint in overall (odds ratio = 3.75, 95% confidence interval, 2.44–5.77, P < 0.001) and in subgroups (all P < 0.05). The accuracy of the ACEF score was equivalent to the other complex risk scores. The combination of ACEF, and diabetes (ACEF-diabetes score) yielded a superior discriminatory ability than the original ACEF score (increase in C-statistic from 0.67 to 0.71, P = 0.048; continuous net reclassification improvement = 51.9%, 95% confidence interval, 33.4–70.5%, P < 0.001; integrated discrimination improvement = 0.020, 95% confidence interval, 0.011–0.030, P < 0.001). Conclusions: The simplified ACEF score performed well in predicting 1-year outcomes in ST-segment elevation myocardial infarction patients undergoing percutaneous coronary intervention. The novel ACEF-diabetes score provided a better predictive value and thus may help stratify high-risk patients and potentially facilitate decision making.
