To observe the effect of continuous renal replacement therapy (CRRT) combined with low-flow extracorporeal membrane oxygenation (ECMO) of V-V mode on anti-inflammation, improving oxygenation and reducing PaCO2 in canines with acute respiratory distress syndrome (ARDS) and hypercapnia. A total of 30 healthy adult canines were randomly divided into sham group (n = 10), ECMO (EC) group (n = 10) and CRRT + ECMO (CR + EC) group (n = 10). https://www.selleckchem.com/Bcl-2.html Sham group was only treated with invasive mechanical ventilation. EC group was also treated with ECMO. CR + EC group was treated with CRRT combined with low-flow ECMO of V-V mode besides invasive mechanical ventilation. The results showed that hazard ratio was lower in the CR + EC group. Inflammatory factors, OI values, and PaCO2 levels were lower in the CR + EC group. There was no significant difference in the levels of MAP, CO and T among the three groups. No significant complications or death was developed in the three groups. Compared with ECMO group at T3, T6 and T9, IL-6 [(276.13 ± 8.32, 262.04 ± 7.15, 259.33 ± 7.31)ng/L VS (352.67 ± 19.24, 360.24 ± 23.58, 362.21 ± 25.24)ng/L] and TNF-α [(50.14 ± 1.75, 50.45 ± 1.81, 48.03 ± 1.24) ng/L VS (70.25 ± 3.02, 72.45 ± 3.25, 76.69 ± 2.18)ng/L] in CR + EC group were decreased (P  less then  0.0001). Compared with sham group, IL-6 [(343.76 ± 21.97, 345.91 ± 19.89, 340.34 ± 22.17)ng/L]and TNF-α [(68.10 ± 2.96, 67.31 ± 3.01, 70.34 ± 3.35)ng/L] of T3, T6 and T9 in CR + EC group were lower (P  less then  0.0001). These findings indicated that CRRT combined with low-flow ECMO of V-V mode had a positive effect on anti-inflammation, oxygenation improvement and surplus blood CO2 removal in canines with ARDS and hypercapnia. These results provide a promising treatment regimen for ARDS.Saxitoxin (STX) is a major marine toxin from shellfish, and it is responsible for paralytic shellfish poisoning (PSP). In this study, a highly sensitive and rapid aptamer assay was developed for STX detection by combining fluorescence resonance energy transfer (FRET) and nuclease-assisted target recycling signal amplification. The aptamer STX-41 conjugated with graphene quantum dots (GQDs) was adsorbed on magnetic reduced graphene oxide (MRGO) to establish a fluorescence quenching system. Then, the binding between STX and aptamer induced the desorption of GQD-aptamer from MRGO and the restoring of fluorescence for the fluorescent determination of STX. The digestion of the target bound aptamer by DNase I could release the target for recycling thus achieving signal amplification. Under the optimized conditions, the aptamer assay showed a wide detection range (0.1-100 ng·mL-1), low detection limit (LOD of 0.035 ng·mL-1), high specificity, good recovery (86.75-94.08% in STX-spiked clam samples) and repeatability (RSD of 4.27-7.34%). Combined with fluorescent detection technology, signal amplification technology, and magnetic separation technology, the proposed method can be used to detect STX in seafood products successfully.Water resources management requires a proper understanding of the status of available and exploitable water. One of the useful management tools is the use of simulation models that are highly efficient in spite of the complex problems in the groundwater sector. In the present study, three data-based models, namely, group method of data handling (GMDH), Bayesian network (BN), and artificial neural network (ANN), have been investigated to simulate the groundwater levels and assess the quantitative status of aquifers. Five observation wells were selected in Birjand aquifer using spatial clustering to analyze and evaluate the aquifer. To determine the effective variables in predicting groundwater level, 10 scenarios were developed by combining several variables, including groundwater level in the previous month, aquifer exploitation, surface recharge, precipitation, temperature, and evaporation. Results showed that the GMDH model with three input variables, i.e., the groundwater level in the previous month, aquifer exploitation, and precipitation, had the highest prediction performance, RMSE, NASH, MAPE, and R2 of which were obtained equal to 0.074, 0.97, 0.0037, and 0.97, respectively. Furthermore, Taylor's diagram showed that the predicted values using the GMDH model had the highest correlation with the observational data. Hydrograph simulation was performed for 6 years to analyze the condition of the aquifer. The results showed that the groundwater level is in critical condition in this aquifer, and a 1.2-m groundwater loss was predicted for this aquifer. The findings of this study show that the management of the studied aquifer is necessary to improve its current situation.Imaging techniques widely use Computed Tomography (CT) scans for various purposes, such as screening, diagnosis, and decision-making. Of all, it holds true for bone injuries. To build fully automated Computer-Aided Detection (CADe) and Diagnosis (CADx) tools and techniques, it requires fairly large amount of data (with gold standard). Therefore, in this paper, since state-of-the-art works relied on small dataset, we introduced a CT image dataset on limbs that is designed to understand bone injuries. Our dataset is a collection of 24 patient-specific CT cases having fractures at upper and lower limbs. From upper limbs, 8 cases were collected from bones in/around the shoulder (left and right). Similarly, from lower limbs, 16 cases were collected from knees (left and right). Altogether, 5684 CT images (upper limbs 2057 and lower limbs 3627) were collected. Each patient-specific CT case is composed of maximum 257 scans/slices in average. Of all, clinically approved annotations were made on every 10th slices, resulting in 1787 images. Importantly, no fractured limbs were missed in our annotation. Besides, to avoid privacy and confidential issues, patient-related information were deleted. The proposed dataset could be a promising resource for the medical imaging research community, where imaging techniques are employed for various purposes. To the best of our knowledge, this is the first time 5K+ CT images on fractured limbs are provided for research and educational purposes.
