    Abstract Seed germination is the complex adaptive trait of higher plants influenced by a large number of genes and environmental factors. Numerous studies have been performed to better understand how germination is controlled by various environmental factors and applied chemicals, such as cyanide. However, still very little is known about the molecular mechanisms of how extrinsic signals regulate seed germination. Our and previous studies found that non-lethal cyanide treatment promotes seed germination, but the regulatory mechanism is unclear. In this study, we found that a low concentration of cyanide pretreatment significantly enhanced the expression of endo-β-mannanase 5 (

    Abstract Study objective: To evaluate the use of dilute carboprost tromethamine injection at the endometrium/myoma junction during hysteroscopy to facilitate myoma expulsion and removal in a single procedure.
    Design: Case series.
    Setting: Single high-volume academic medical center.
    Patients: Seven patients aged 32 to 51 years old with FIGO type 2 uterine myomas and symptoms of abnormal uterine bleeding or infertility undergoing hysteroscopic resection with a morcellation device from November 2022 to July 2023.
    Intervention: Dilute injection of carboprost tromethamine (10 µg/mL) at time of hysteroscopic myomectomy.
    Measurements and main results: The main outcome measure was ability to complete the hysteroscopic myomectomy in a single procedure using a hysteroscopic morcellator. Secondary outcomes included total operative time, fluid deficit, and postoperative pharmacologic side effects and/or surgical complications. Among our 7 patients, all had successful single procedure complete resections of myomas ranging from 0.9 to 4.6 cm in maximal diameter. Average operative time was 30 minutes, and average fluid deficit was approximately 839 mL. The carboprost dosages used ranged from 30 to 180 µg. One patient experienced prolonged postoperative nausea and vomiting that resolved with antiemetics. One patient experienced postoperative endometritis that improved with antibiotics.
    Conclusion: In this pilot study, injection of dilute carboprost intraoperatively facilitated one-step hysteroscopic myomectomy of FIGO 2 myomas, via enhanced extrusion of the intramural portion of the fibroid into the uterine cavity, with both short operative times and acceptable fluid deficits.

    Abstract Seed germination is the complex adaptive trait of higher plants influenced by a large number of genes and environmental factors. Numerous studies have been performed to better understand how germination is controlled by various environmental factors and applied chemicals, such as cyanide. However, still very little is known about the molecular mechanisms of how extrinsic signals regulate seed germination. Our and previous studies found that non-lethal cyanide treatment promotes seed germination, but the regulatory mechanism is unclear. In this study, we found that a low concentration of cyanide pretreatment significantly enhanced the expression of endo-β-mannanase 5 (MAN5) gene in Arabidopsis thaliana, and the mutation of this gene impaired cyanide-mediated seed germination. In contrast, overexpression of MAN5 gene enhanced Arabidopsis seed germination ability under both normal and salt stress conditions. Further studies showed that the expression of the MAN5 gene was negatively regulated by ABA insensitive 5 (ABI5); In abi5 mutant seeds, the expression of the MAN5 gene was increased and the seed germination rate was accelerated. Additionally, cyanide pretreatment markedly reduced the gene expression of ABI5 in Arabidopsis seeds. Taken together, our data support the involvement of MAN5 as a key gene in cyanide-mediated seed germination and confirm the role of ABI5 as a critical negative factor involved in cyanide-regulated MAN5 gene expression.

    Abstract Human papillomavirus type 16 (HPV16) E7 oncoprotein plays an essential role in cervical carcinogenesis and is encoded predominantly by an E6*I mRNA through alternative RNA splicing of a P97 promoter-transcribed bicistronic E6E7 pre-mRNA. Recently, an HPV16 circular RNA, circE7, was detected in two HPV16-positive cervical cancer cell lines, CaSki and SiHa. It was generated through back-splicing of the E6E7 pre-mRNA. The reported findings showed that, because viral E6*I RNA was nuclear, E7 was mainly translated from the cytoplasmic circE7, and knockdown of circE7 in CaSki cells led to reduction of E7 oncoprotein, cell proliferation, and xenograft tumor formation. We have reanalyzed the published data, conducted detailed experiments, and found that the circE7 in CaSki cells is only 0.4 copies per cell, which is ∼1,640-fold lower than E6*I RNA and also barely detectable from two W12 subclone cell lines, 20861 (integrated HPV16) and 20863 (extrachromosomal HPV16) cells derived from a low-grade cervical lesion. We also determined HPV16 E6*I and E6*II RNAs in CaSki cells are mainly cytoplasmic in cell fractionation analyses, as reported in other studies. We further demonstrated that the claimed circE7 functions in the published report have resulted from off-target effects on E6*I RNA by the circE7 small interfering RNAs used in the reported study.

    Abstract At the early stage of development, China has a monotonous energy consumption structure dominated by coal, which damages the environment and has adverse impacts on the economy and sustainable development of the country. It is urgent to change the existing energy structure to reach the goal of sustainable development and improve people’s living standard. The U.S., as the world’s strongest power, has been where China is now, so it is feasible to draw lessons from the U.S in its energy consumption structure. In this study, massive data about the changes in the energy consumption structure are collected and processed, and the types of energy in China and the U.S. are compared. In 2030, China will become the largest consumer of petroleum, and the problems in China’s energy consumption such as supply-demand imbalance, low utilization of energy, and overdependence on imports, will rear their ugly heads. Thus, through theoretical analysis and data analysis, we analyze China’s current structure of energy consumption, its similarity with and difference from that in the U.S., and propose suggestions to improve China’s energy consumption structure.

    Abstract Aim: To evaluate the status quo of knowledge, attitude and behaviour of neonatal nurses on medical adhesive related skin injury (MARSI).
    Design: A survey.
    Methods: We conducted a survey on the knowledge, attitude and behaviour of neonatal nurses from September 1-30, 2022. The characteristics, knowledge, attitude and behaviour of neonatal nurses were evaluated and analysed.
    Results: A total of 116 neonatal nurses were included. Multivariate regression analysis indicated that had accepted MARSI training, education level, year of work experience are the influencing factors of nurses' MARSI knowledge score (all p < 0.05). Had accepted MARSI training, year of work experience are the influencing factors of nurses' MARSI attitude score (all p < 0.05). Had accepted MARSI training, year of work experience are the influencing factors of nurses' MARSI behaviour score (p = 0.015).
    Patient contribution: Neonatal nurses should strengthen their learning and training of MARSI related knowledge, and standardize their protective behaviours to reduce MARSI.

    Abstract SRSF3 (SRp20) is the smallest member of the serine/arginine (SR)-rich protein family. We found the annotated human SRSF3 and mouse Srsf3 RefSeq sequences are much larger than the detected SRSF3/Srsf3 RNA size by Northern blot. Mapping of RNA-seq reads from various human and mouse cell lines to the annotated SRSF3/Srsf3 gene illustrated only a partial coverage of its terminal exon 7. By 5' RACE and 3' RACE, we determined that SRSF3 gene spanning over 8422 bases and Srsf3 gene spanning over 9423 bases. SRSF3/Srsf3 gene has seven exons with exon 7 bearing two alternative polyadenylation signals (PAS). Through alternative PAS selection and exon 4 exclusion/inclusion by alternative RNA splicing, SRSF3/Srsf3 gene expresses four RNA isoforms. The major SRSF3 mRNA isoform with exon 4 exclusion by using a favorable distal PAS to encode a full-length protein is 1411 nt long (not annotated 4228 nt) and the same major mouse Srsf3 mRNA isoform is only 1295 nt (not annotated 2585 nt). The difference from the redefined RNA size of SRSF3/Srsf3 to the corresponding RefSeq sequence is at the 3' UTR region. Collectively, the redefined SRSF3/Srsf3 gene structure and expression will allow better understanding of SRSF3 functions and its regulations in health and diseases.

    Abstract Instruction: Lynch syndrome (LS) is the most common inherited cancer predisposition disorder of colorectal cancer (CRC) which is associated with pathogenic variants in 4 mismatch repair (MMR) genes. Here, we reported a multi-generation Chinese family clinically diagnosed with LS.
    Methods: To identify the underlying pathogenic gene variants, 30 whole blood samples and 4 colorectal cancer tissue samples and their clinical data were obtained from this four-generation family. Microsatellite instability-high (MSI) testing, immunohistochemistry (IHC), and Whole-Exome Sequencing (WES) were performed to identify the MMR/MSI and the underlying gene variants. The minigene splicing assay and in vitro splicing assay were used to explore the function of this variant.
    Results: MSI-H and dMMR was revealed by the MSI testing and IHC, Whole-Exome Sequencing (WES) in 3 patients successfully identified a splicing variant (c.793-1G>A) in intron 4 of MSH2. Sanger sequencing validated the WES results, and all the "healthy" individuals carrying the variant have been identified in the family by PCR. Bioinformatics analysis and in vitro minigene assay showed that the pathogenic variant affected the splicing process of MSH2 gene to generate 2 kinds defective transcription products, and consequently reduced the expression of MSH2 protein. The mutation carriers were later recommended for colonoscopy and other important cancer diagnostic inspections every 1-2 years because they both have a higher risk of LS.
    Discussion: We found a pathogenic splicing variant (rs863225397, c.793-1G>A) of MSH2 gene, and furtherly confirmed that this mutation plays an important role in LS patients of this pedigree based on the vitro study. Our study indicates that one splicing mutation in the MSH2 gene (c.793-1G>A) causes LS and highlights the importance of LS gene testing.

    Abstract Background: Cyanide is a toxic chemical that inhibits cellular respiration. In plants, cyanide can be produced by themselves, especially under stressful conditions. Cyanoalanine synthase (CAS) is a key enzyme involved in plant cyanide detoxification. There are three genes encoding CAS in Arabidopsis thaliana, but the roles of these genes in the plant's response to stress are less studied. In addition, it is known that alternative oxidase (AOX) mediates cyanide-resistant respiration, but the relationship between CAS and AOX in regulating the plant stress response remains largely unknown.
    Results: Here, the effects of the overexpression or mutation of these three CAS genes on salt stress tolerance were investigated. The results showed that under normal conditions, the overexpression or mutation of the CAS genes had no significant effect on the seed germination and growth of Arabidopsis thaliana compared with wild type (WT). However, under 50, 100, and 200 mM NaCl conditions, the seeds overexpressing CAS genes showed stronger salt stress resistance, i.e., higher germination speed than WT seeds, especially those that overexpressed the CYS-C1 and CYS-D1 genes. In contrast, the seeds with CAS gene mutations exhibited salt sensitivity, and their germination ability and growth were significantly damaged by 100 and 200 mM NaCl. Importantly, this difference in salt stress resistance became more pronounced in CAS-OE, WT, and mutant seeds with increasing salt concentration. The CAS-OE seeds maintained higher respiration rates than the WT and CAS mutant seeds under salt stress conditions. The cyanide contents in CAS mutant seeds were approximately 3 times higher than those in WT seeds and more than 5 times higher than those in CAS-OE seeds. In comparison, plants overexpressing CYS-C1 had the fastest detoxification of cyanide and the best salt tolerance, followed by those overexpressing CYS-D1 and CYS-D2. Furthermore, less hydrogen sulfide (H
    Conclusion: In summary, the findings of the present study suggest that overexpression of Arabidopsis CAS family genes plays a positive role in salt stress tolerance and highlights the contribution of AOX to CAS-mediated plant salt resistance, mainly by reducing cyanide and H

    Abstract Background: Uterine artery embolization (UAE) has been used to treat symptomatic uterine leiomyomas since 1995. This case report describes a rare complication of UAE, with delayed recognition, ultimately requiring definitive hysterectomy.
    Case: A 53-year-old women with symptomatic leiomyomas underwent imaging demonstrating an enlarged (16.9×11.3×11.5 cm) uterus with multiple leiomyomas. She underwent UAE and, over the subsequent 3 months, and had five emergency department visits for abdominal pain and dysuria. Pelvic magnetic resonance imaging (MRI) 4 months postprocedure showed nodular mural enhancement of the right anterior bladder dome, and cystoscopy demonstrated irregular tissue on the right dome of the bladder. The patient ultimately underwent total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, partial cystectomy with reconstruction, and omental flap for bladder necrosis and leiomyoma fistulization.
    Conclusion: Bladder necrosis and leiomyoma fistulization are rare complications of UAE that can present with pelvic pain, hematuria, and recurrent bladder stones. Computed tomography and MRI can be useful tools in evaluating for complications, but clinicians should have a low threshold to use cystoscopy to directly visualize potential abnormalities identified on imaging. Patients with complex cases with suspected post-UAE complications warrant referral to tertiary care centers for a multidisciplinary approach.
