AbstractIn order to improve the efficiency and safety of shield machine cutting reinforced concrete piles, abrasive waterjets (AWJs) assisted mechanical combined cutting technology is considered a feasible solution. However, the water-rich flooding environment will cause the cutting performance of AWJs to weaken, which brings great challenges to the application of this technology. In order to analyze the influence of submerged conditions on the cutting performance of AWJs, the cross-sectional morphology of reinforced concrete piles cut by AWJs is explored using indoor experiments, and the weakening law of pile foundation cutting depth is revealed. The results show that the submerged environment greatly weakens the cutting ability, and the average cutting depth is reduced by about 20.0%. Rebar materials are more difficult to remove due to their high strength and strong plastic toughness, which is the root reason of the difficulty in cutting off piles. As the cutting times increases, the cutting depth discount factor initially decreases rapidly before stabilizing. At 380 MPa, the cutting depth discount factor remains stable at 0.49, while at 280 MPa, it stabilizes at 0.62. The findings presented in this paper can provide guidance and suggestions on waterjet parameters for AWJs assisted shield machine pile breaking.HIGHLIGHTSThe cross-sectional change rules of reinforced concrete pile foundation cut by abrasive waterjets is clarified.The depth weakening effect of pile foundations cut by abrasive waterjets under submerged conditions is revealed.The cutting depth discount factor for rebars is established.The cross-sectional change rules of reinforced concrete pile foundation cut by abrasive waterjets is clarified.The depth weakening effect of pile foundations cut by abrasive waterjets under submerged conditions is revealed.The cutting depth discount factor for rebars is established.

Curcumin (Cur) considered as a golden nutraceutical, is emerging as one of bioactive compounds demonstrating the most promising biological activities, including antioxidant, antibacterial, anti-inflammatory, anticancer. It is also used for coloring and seasoning in foods. However, Cur applications are limited due to factors like low aqueous solubility, poor colloidal stability and bioavailability. Extensive efforts were made using pure zein (Ze) to develop nanoparticles (NPs) for encapsulation of Cur to overcome the aforementioned issues. Nevertheless, zein nanoparticles (ZeNPs) have limitations related to their instability to neutral pH and rapid degradation by gastric proteases. Thus, the combination between Ze and different biopolymers to produce zein nanocomposites (ZeNCs) for improving the stability of ZeNPs were scrutinized in this study. The mass ratio of Ze/polymer played a critical in the formation and stability of ZeNCs. Electrostatic attraction, hydrogen bonding and intermolecular interaction were responsible for ZeNCs formation. High encapsulation efficiency (EE), storage stability, solubility, bioaccessibility, intestinal permeability and antioxidant activity (AA) for Cur were achieved in ZeNCs compared to ZeNPs. ZeNCs did not show toxicity towards normal NCM460 and 293 cells, but potent anticancer activity against MCF-7, HepG2, Hela, and HCT 116 cells. ZeNCs displayed potential applications in different food matrices. [ABSTRACT FROM AUTHOR]

As the 'twin imagers', Himawari-8/AHI and Himawari-9/AHI are both the new generation imagers operated by the Japan Meteorological Agency (JMA). After more than 7 years of operation, Himawari-8/AHI turned into stand-by status and Himawari-9/AHI began operation as the successor. To continuous users of both imagers, it is essential to characterize continuity of Himawari-8/AHI to Himawari-9/AHI observations, which can provide beneficial information to quantitative retrieval and satellite assimilation algorithm developer. In this research, cross-comparison are performed to Himawari-8/AHI and Himawari-9/AHI infrared (IR) observations, and 'observation minus background (O - B)' characters of two imagers under clear-sky condition over ocean are also compared. The results are as follows: 1) Himawari-8/AHI and Himawari-9/AHI IR observations are in good consistency with largest absolute bias less than 1.437 K and RMSE below 1.663 K. Biases and RMSEs for Himawari-8/AHI and Himawari-9/AHI channel 7 show obvious diurnal variation character and RMSEs for all channels have evident temporal cycle variation characteristics, with cycle time of about 10 days; 2) IR observations of Himawari-8/AHI are more closed to RTTOV simulations under clear-sky condition than those of Himawari-9/AHI, especially for channels 7, 9 and 16. Dependence of O – B biases and RMSEs for two imagers IR channels on satellite scan angles are almost identical. [ABSTRACT FROM AUTHOR]

This study aimed to assess the effect of individualized enteral nutrition management based on the prognostic nutrition index (PNI) on surgical patients with oral malignancies. This quasi-experimental pilot study consecutively included patients diagnosed with oral malignancies who underwent radical surgery in Ningbo No. 2 Hospital between January 2020 and May 2023. The primary outcome was PNI. A total of 71 patients with oral malignancies were enrolled, and 35 patients received PNI-based individualized enteral nutrition management. The PNI group displayed significantly higher PNI than the routine enteral nutrition support group (1st week postoperatively: 39.86 ± 3.86 vs. 37.29 ± 4.23, p < 0.001. 2nd weeks postoperatively: 44.17 ± 4.36 vs. 40.72 ± 3.40, p < 0.001). The surgical suture removal time and length of hospital stay (both p < 0.001) in the PNI group were significantly shorter than in the routine enteral nutrition support group. At 1 month postoperatively, the PNI group had significantly higher scores of QoL (p = 0.002) than the routine enteral nutrition support group. The individualized enteral nutrition management based on the PNI could improve the nutritional status of postoperative patients with oral malignancy, which could facilitate postoperative rehabilitation and improve overall QoL.

Colorectal cancer (CRC) is a prevalent tumour with high morbidity rates worldwide, and its incidence among younger populations is rising. Early diagnosis of CRC can help control the associated mortality. Fungi are common microorganisms in nature. Recent studies have shown that fungi may have a similar association with tumours as bacteria do. As an increasing number of tumour-associated fungi are discovered, this provides new ideas for the diagnosis and prognosis of tumours. The relationship between fungi and colorectal tumours has also been recently identified by scientists. Therefore, this paper describes the limitations and prospects of the application of fungi in diagnosing CRC and predicting CRC prognosis. [ABSTRACT FROM AUTHOR]
