Abstract
BACKGROUND In order to improve the drying efficiency and reduce the drying energy consumption of Pleurotus eryngii, microwave hot-air flow rolling drying (MHARD) coupled with ultrasonic pretreating time (0, 20, 40, and 60 min) was used to investigate the drying profile, thermal characteristics, water migration, microstructure and rehydration dynamics of P. eryngii using differential scanning calorimetry (DSC), low-field nuclear magnetic resonance (LF-NMR) analysis and scanning electron microscopy (SEM). RESULTS Results showed that the drying time of P. eryngii was 80, 70, 60 and 50 min, accordingly. Energy consumption was significantly reduced by ultrasonic pretreatment, and moisture effective diffusivity (Deff ) was increased with the increase of ultrasonic pretreating time. DSC curves showed that the drying process was accelerated by ultrasonic pretreatment significantly by enhancing the heat transfer. Meanwhile, SEM images showed that the cell was broken and numbers of irregular holes appeared in the ultrasound-pretreated samples. In terms of rehydration dynamics, Page model could well model the rehydration kinetics of dried P. eryngii with R2 > 0.99. CONCLUSION The findings indicate that ultrasonic pretreatment is a promising method for MHARD of P. eryngii as it can enhance the drying process, and show potential for industrial application. © 2021 Society of Chemical Industry.

Abstract
The present study aimed to investigate the effect of hot air drying (HD), microwave rolling-bed drying (MRD), hot air microwave rolling-bed drying (HMRD), pulse-spouted microwave vacuum drying (PSMVD) and freeze-drying (FD) on the drying characteristics, quality properties and microstructure of edamame. Six models were fitted the drying curves, and quality attributes were analyzed. Results indicated that Page model was the most suited model for edamame drying. Compared with HD, MRD and HMRD improved the quality of edamame and decreased the drying time by 45.59% and 36.03% respectively. The FD and PSMVD possessed higher rehydration ability, nutrient retention and antioxidant capacity compared with other methods. Moreover, PSMVD products showed a crunchy texture, the less color change and the shortest drying time (70 min). Microscopy images demonstrated a distinct porous structure in PSMVD, which facilitated the moisture transfer. Overall, PSMVD is a promising dehydration method for obtaining high value-added edamame products.

Abstract
Platycodon grandiflorus (Jacq.) A.DC. roots (PGR), a Chinese herb with medicinal and edible value, was powdered by freeze drying (FD) and spray drying (SD) after maceration extraction (ME) or ultrasound-assisted extraction (UAE) to develop a new functional food product. Four PGR powders were obtained namely ME-FD, ME-SD, UAE-FD, and UAE-SD and their powder quality, structural properties, and functionalities were evaluated. UAE-FD powder had the highest powder recovery (85.3 ± 5.79%) and also presented better hydration properties due to the larger particle size compared with other three PGR powders. Four PGR powders exhibited similar thermal decomposition process, molecular structure, amorphous characteristics, amino acids composition, and taste profiles. Furthermore, the UAE-FD PGR powders presented the highest Platycodin D (3.68 ± 0.04 mg/g), total phenolic (2.84 ± 0.11 mg GAE/g), and total flavonoids content (2.11 ± 0.14 mg RE/g), resulting in best antioxidant activity (58.67 ± 2.42 μmol Trolox/g). Therefore UAE-FD is an environment-friendly technique for the production of functional PGR powder with improved nutritional and redispersion properties.

Abstract
The prognosis of lung cancer remains poor due to the limited biomarker selection for treating patients with optimal chemotherapy. The aim of this study is to discover and identify new biomarkers with the value of predicting chemotherapy responses in a lung adenocarcinoma (AD) specimen. In this study, six pairs of pre-treatment fresh primary lung AD-cancer tumors with varied chemotherapy responses were used to discover new biomarkers by two-dimensional difference gel electrophoresis (2D DIGE). Among the matched protein spots, 19 were up-regulated and 18 were down-regulated in chemo-sensitive tumors versus chemo-resistant tissues. These differentially expressed proteins could be divided into five classes: redox regulation protein, the cytoskeletal protein, cell metabolism enzymes or proteins, apoptosis, signal transduction mediated molecules, and other functional proteins. Proteins of interest, including PRDX2, PRDX6, and Gelsolin, were differentially expressed in chemo-sensitive tumors versus chemo-resistant tissues and these observations were validated by immunohistochemistry in 92 formalin-fixed and paraffin-embedded (FFPE) specimens. Our results demonstrated that PRDX6 protein expression was closely related to tumor response (cc2 = 5.57, P < 0.05), whereas no relationship of PRDX2 and Gelsolin were obtained with tumor response (cc2 = 0.51 P > 0.05, cc2 = 0.41 P > 0.05). This tissue proteomics study provides evidence that PRDX6 may be regarded as a predictive biomarker for poor chemotherapy response, which can be helpful in guiding pretreatment protocols.

Abstract
On March 11, 2020, WHO officially declared that COVID-19 had become Pandemic. As of March 31, the epidemic had affected more than 178 countries and regions, with more than 780 000 confirmed cases. The Pandemic Influenza Preparedness Framework for the sharing of influenza viruses and access to vaccines and other benefits (the 'PIP Framework' or 'Framework') is an international arrangement adopted by the World Health Organization in May 2011 to improve global pandemic influenza preparedness and response. Since the transmission route and transmission capacity of COVID-19 are similar to that of influenza A (H1N1) in 2009, which conforms to the basic elements of "human pandemic", and the epidemic scale has exceeded that of influenza A (H1N1), it is probable to incorporate COVID-19 epidemic response into PIPF, and at the same time to verify and improve PIPF in practice. It is recommended that WHO, other international organizations and relevant countries make full use of the PIPF system to respond to the epidemic and better coordinate national actions at the global level. At the same time, China should also make the planning and deploy of domestic epidemic prevention and control and international epidemic cooperation under the framework.

Abstract
Objective: To evaluate the impact of KIT D816 mutation on the salvage therapy in relapsed acute myeloid leukemia (AML) with t(8;21) translocation. Method: The characteristics of the first relapsed AML with t(8;21) translocation from 10 hospitals were retrospectively collected, complete remission (CR(2)) rate after one course salvage chemotherapy and the relationship between KIT mutation and CR(2) rate was analyzed. Results: 68 cases were enrolled in this study, and 30 cases (44.1%) achieved CR(2). All patients received KIT mutation detection, and KIT D816 mutation was identified in 26 cases. The KIT D816 positive group had significantly lower CR(2) compared with non-KIT D816 group (23.1% vs 57.1%, χ(2)=7.559, P=0.006), and patients with longer CR(1) duration achieved significantly higher CR(2) than those with CR(1) duration less than 12 months (74.1% vs 31.9%, χ(2)=9.192, P=0.002). KIT D816 mutation was tightly related to shorter CR(1) duration. No significant difference of 2 years post relapse survival was observed between KIT D816 mutation and non-KIT D816 mutation group. Conclusion: KIT D816 mutation at diagnosis was an adverse factor on the salvage therapy in relapsed AML with t(8;21) translocation, significantly related to shorter CR1 duration, and can be used for prediction of salvage therapy response. KIT D816 mutation could guide the decision-making of salvage therapy in relapsed AML with t(8;21) translocation.

Abstract
Synthetic biology tools, such as modular parts and combinatorial DNA assembly, are routinely used to optimise the productivity of heterologous metabolic pathways for biosynthesis or substrate utilisation, yet it is well established that host strain background is just as important for determining productivity. Here we report that in vivo combinatorial genomic rearrangement of Saccharomyces cerevisiae yeast with a synthetic chromosome V can rapidly generate new, improved host strains with genetic backgrounds favourable to diverse heterologous pathways, including those for violacein and penicillin biosynthesis and for xylose utilisation. We show how the modular rearrangement of synthetic chromosomes by SCRaMbLE can be easily determined using long-read nanopore sequencing and we explore experimental conditions that optimise diversification and screening. This synthetic genome approach to metabolic engineering provides productivity improvements in a fast, simple and accessible way, making it a valuable addition to existing strain improvement techniques. The Sc2.0 project has built the Synthetic Chromosome Rearrangement and Modification by LoxP-mediated Evolution (SCRaMbLE) system into their synthetic chromosomes. Here the authors use SCRaMbLE to rapidly develop, diversify and screen strains for diverse production and growth characteristics.

Abstract
Solid milk fat stearin (S25) can be a promising oxidation retarder due to its capacity to entrap liquid oils, especially for incorporating omega-3 (ω-3) rich oils into dairy products. Thermal properties of S25/ω-3 rich oil mixtures are necessary for such application. The effects of S25 on the crystallization and melting behaviours of ω-3 rich oils, namely fish oil (FO), linseed oil (LO) and krill oil (KO), were investigated by differential scanning calorimetry (DSC). Thermograms showed that with S25 concentration increasing, transitions of FO and LO shifted to lower and largely to higher temperatures, respectively, while crystallization temperature of KO slightly decreased. Negative, positive and low values of interaction enthalpy (ΔHint) suggested the adverse, beneficial and limited effect of S25 on the crystallization of S25/FO, S25/LO and S25/KO mixtures, respectively. LO could have the best oxidative stability upon the addition of S25 since their interactions facilitated earlier and stronger crystallization.

Abstract
In this present work, the characteristics of hazardous gas dispersion and possible cross-unit contamination around a complex-shaped high-rise residential building due to wind effect are thoroughly studied using physical modeling method. Experiments were performed in a boundary layer wind tunnel for a 1:30 scale model that represented a 10-story residential building in prototype. Tracer gas, simulating exhausted room air, was continuously released from different floor levels, and its concentrations on the adjacent envelope surfaces were measured using fast flame ionization detectors. The mean concentration fields were reported and analyzed under different configurations during the experiment to consider the effects on pollutant dispersion behavior due to changes in source position and approaching wind condition, with the main emphasis on the differences between open-window and closed-window conditions. In particular, the measured concentration fields were further examined from a practical point of view, with respect to hazard assessment. Understanding these hazardous plume dispersion features is useful for employing effective intervention strategies in modern residential building environment in case of hazardous substance release. The study on this physical process is not only helpful to reduce the hazardous effect of routine release of harmful pollutant near the building, but also useful for the purpose of prevention and control of accidental infectious diseases outbreak.

Abstract
In this present work, the characteristics of hazardous gas dispersion and possible cross-unit contamination around a complex-shaped high-rise residential building due to wind effect are thoroughly studied using physical modeling method. Experiments were performed in a boundary layer wind tunnel for a 1:30 scale model that represented a 10-story residential building in prototype. Tracer gas, simulating exhausted room air, was continuously released from different floor levels, and its concentrations on the adjacent envelope surfaces were measured using fast flame ionization detectors. The mean concentration fields were reported and analyzed under different configurations during the experiment to consider the effects on pollutant dispersion behavior due to changes in source position and approaching wind condition, with the main emphasis on the differences between open-window and closed-window conditions. In particular, the measured concentration fields were further examined from a practical point of view, with respect to hazard assessment. Understanding these hazardous plume dispersion features is useful for employing effective intervention strategies in modern residential building environment in case of hazardous substance release. The study on this physical process is not only helpful to reduce the hazardous effect of routine release of harmful pollutant near the building, but also useful for the purpose of prevention and control of accidental infectious diseases outbreak.

Abstract
The hepatitis C virus RNA polymerase (NS5B) is strictly required for viral replication and thus represents an attractive target for antiviral drug development. In this study, stable HeLa cell lines with an integrated NS5B gene were selected by G418 and then confirmed by genome PCR. Subsequently, transcription and expression of the integrated NS5B genes were demonstrated by RT-PCR and Western blot analysis. Further analysis demonstrated enzymatic activity of the expressed NS5B polymerase. The stable HeLa cell lines should be useful for the identification of NS5B inhibitors and for studying the mechanisms of HCV replication.

Abstract
Two hundred eighty five cases of ectopic pregnancy in Beijing area from Jan. 1 to Dec. 31 1990 including 150 cases of intrauterine devices (IUD) and 135 cases of non-IUD users were studied. Clinico-pathological observation included the history of pelvic inflammatory disease, the site of ectopic pregnancy, the classification of previous tubal inflammation of the ectopic side and other pathologic lesions, the side of the corpus luteum of pregnancy and histology of endometrium, etc. Besides, using stereologic technique the cilia length and cilia density of endosalpinx were studied in 50 cases through image analysis system. Results showed that except for a significant higher frequency of ovarian pregnancy in IUD-users, there was no significant differences between the 2 groups. It indicated that the degree of injury of fallopian tubes and the factors causing the damage were similar in both groups. The authors concluded that IUD does not increase the risk of fallopian tube lesions.

Abstract
The stereological study was carried out in 8 normal and 22 IUGR placentas through Image Analysis System of Cambridge Instruments Quantimet 970 and 10 indices were analysed. The results showed that in the IUGR group the placental indices of total surface area of acroteric villus, total volume of intervillous space, volume density of fetal capillaries, total volume of fetal capillaries and surface area density of vasculo-syncytial membrane were significantly reduced than those in the normal group. The vasculo-syncytial membrane became significantly thick in the IUGR placental group. It was confirmed that a close relation exists between IUGR and placental quantitative changes. The major pathological findings of the placenta were prematuration and hypoplasia.
