Drought stress, as a key negative factor, could result in the reduction of yield and quality in rice. Myo-inositol oxygenase (MIOX), a unique monooxygenase, exerts an essential role in plant drought resistance. To investigate the function of the OsMIOX gene in drought process, a transcriptomic profile between OsMIOX-overexpressing (OE) plants and wild-type (WT) was performed by RNA-sequencing in rice. Under drought stress, a total of 23 million high-quality reads, assembled into 28,552 unigenes, were generated and 743 genes (534 up-regulated and 209 down-regulated) were significantly differentially expressed between OE plants and WT. These detected genes were mainly associated with plant hormones transduction and sugar metabolism. Interestingly, several transcription factors (TFs) were prominently identified in OE lines. A significant positive correlation between RNA-Seq data and qRT-PCR results was identified. In all, our results could partially provide relatively valuable clues in identifying candidate genes involved in drought-stress resistance and elucidating basis theory underlying the role of OsMIOX in drought resistance.

Background: More and more research indicate that the immediately early response gene 3 (IER3) is involved inmany biological provesses, such as apoptosis and immunoreaction, as well as viral infection, tumorigenesis and tumour progression. Methods: Here we describe the construction of an eukaryotic expression vector containing IER3 gene and its expression in A549 cells as assessed through fluorescence microscopyand Western-blotting. Results: Fluorescence detection displayed that GFP in cytoplasm was high during 48 and 72 hours post-transfection. In addition, Western blotting showed significant increase in IER3 gene expression in the transfected cells compared with controls. Conclusion: The recombinate plasmid expression vector was constructed successfully, which may provide a basis for further exploration of function of IER3 in lung cancer.

<P>PPDO was successfully electrospun into continuous, ultrafine fibers by using DMSO as solvent for the first time. The concentration of PPDO in DMSO and the electrospinning temperature were optimized. PPDO/LAP nanocomposites were also electrospun in DMSO. At 70 degrees C, ultrafine PPDO fibers were obtained from 35 wt% solution and the PPDO/LAP nanocomposite fibers were yielded from 55 wt% solution. Electrospun fibers of the PPDO/LAP nanocomposites showed higher degree of crystallinity due to the presence of embedded nanoparticles.</P>

PURPOSE This study aimed to examine the relationship among participation motivation (PM), involvement (IN), satisfaction (SA), and adherence (AD) in middle school basketball participants in China. METHOD Participants were recruited from 10 middle schools in Changchun, Tonghua, Baicheng, Yanbian, and Siping in Jilin Province, China. A total of 800 questionnaires were distributed, and around 793 questionnaires were used for the final analysis. Data were analyzed using SPSS 26 and AMOS 23. RESULT This study determined the PM, IN, SA, and AD of middle school basketball participants through quantitative analysis. Through the establishment and verification of the structural equation model, the following findings were revealed: first, PM directly affects IN. Second, PM directly affects the development of AD. Third, PM directly affects SA. Fourth, IN does not affect SA. IN directly affects the development of AD. Sixth, SA directly affects the development of AD. CONCLUSION To improve the AD of middle school students to participate in basketball, physical education managers and teachers in Jilin Province should first master students' PM and adopt strategies to strengthen it. They must understand students' needs for basketball participation through their IN while improving their SA. This study provides a theoretical reference for Chinese middle school basketball-related researchers. It may provide corresponding methods and strategies for increasing middle school students' basketball AD, thereby further aiding the steady development of the sport in Chinese middle schools.

Acute graft-versus-host disease (GVHD) following liver transplantation is a rare but fatal complication. The correct diagnosis and management of GVHD after liver transplantation are still major challenges. Herein, we reported successful salvage treatment of acute GVHD by withdrawal of immunosuppression in a patient who presented with fever, skin rashes, and decreased blood cell counts after liver transplantation. This case highlights the need for awareness of drug-induced liver injury if liver function tests are elevated during treatment, especially in patients taking multiple potentially hepatotoxic drugs, such as broad-spectrum antibiotics. When occurs, an artificial liver support system is a useful tool to provide temporary support of liver function for the patient in the event of drug-induced liver injury.

Background: Both alcohol and aqueous extracts of Sauromatum giganteum(Engl.) Cusimano and Hett, the dried root tuber of which is named Baifuzi in Chinese, have been used for folklore treatment of cancer in Northeast of China. However, little is known about which is most suitable to the cancer therapy. Materials and Methods: Serum pharmacology and MTT assays were adopted to detect the effects of ethanol and aqueous extracts of Sauromatum giganteum(Engl.) Cusimano and Hett, prepared by heat reflux methods, on proliferation of different cancer cells. Results: Cancer cells treated with medium supplemented with 10%, 20%, 40% serum(v/v) containing ethanol extract had a decline in viability, with inhibition rates of 7.69%, 21.8%, 41.9% in MCF-7 cells, 42.8%, 48.1%, 51.8% in SGC-7901 cells, 44.1%, 49.2%, 53.7% in SMMC-7721 cells, 6.8%, 15.2%, 39.8% in HepG2 cells, 7.57%, 16.3%, 36.2% in HeLa cells, 6.24%, 12.5%, 27.4% in A549 cells, and 7.20%, 17.5%, 31.3% in MDA-MB-231 cells, respectively. Viability in the aqueous extract groups was no different with that of controls. Conclusions: An ethanol extract of Sauromatum giganteum(Engl.) Cusimano and Hett inhibited the proliferation of SMMC-7721, SGC-7901 and MCF-7 cells, which supports the use of alcoholic but not aqueous extracts for control of sensive cancers, which might include hepatocarcinoma, gastric cancer and breast cancer.

Coenzyme Q10 (CoQ10) is a widely used supplement in heart diseases treatment or antioxidative dietary. The microbial production of CoQ10 was enhanced by addition of solanesol and novel precursors recovered from waste tobacco. The novel precursors were separated by silica gel and identified as α-linolenic acid (LNA) and butylated hydroxytoluene (BHT) based on the effect on CoQ10 production and GC-MS. The effects of novel precursors on CoQ10 production by Sphingomonas sp. ZUTE03 were further evaluated in a two-phase conversion system. The precursor`s combination of solanesol (70mg/l) with BHT (30mg/l) showed the best effect on the improvement of CoQ10 yield. A maximal CoQ10 productivity (9.5 mg l-1 h-1) was achieved after 8h conversion, with a molar conversion rate of 92.6% and 92.4% on BHT and solanesol, respectively. The novel precursors, BHT and LNA in crude extracts from waste tobacco leaves, might become potential candidates for application in the industrial production of CoQ10 by microbes.

<P>Most agronomical traits exhibit quantitative variation, which is controlled by multiple genes and are environmentally dependent. To study the genetic variation of flowering time in Brassica napus, a DH population and its derived reconstructed F(2) population were planted in 11 field environments. The flowering time varied greatly with environments; 60% of the phenotypic variation was attributed to genetic effects. Five to 18 QTL at a statistically significant level (SL-QTL) were detected in each environment and, on average, two new SL-QTL were discovered with each added environment. Another type of QTL, micro-real QTL (MR-QTL), was detected repeatedly from at least 2 of the 11 environments; resulting in a total of 36 SL-QTL and 6 MR-QTL. Sixty-three interacting pairs of loci were found; 50% of them were involved in QTL. Hundreds of floral transition genes in Arabidopsis were aligned with the linkage map of B. napus by in silico mapping; 28% of them aligned with QTL regions and 9% were consistent with interacting loci. One locus, BnFLC10, in N10 and a QTL cluster in N16 were specific to spring- and winter-cropped environments respectively. The number of QTL, interacting loci, and aligned functional genes revealed a complex genetic network controlling flowering time in B. napus.</P>
