IMPACT OF CLIMATE CHANGE ON COASTAL ECOSYSTEM AND OUTDOOR ACTIVITIES: A COMPARATIVE ANALYSIS AMONG FOUR LARGEST COASTLINE COVERING COUNTRIES.

Climate change and coastal ecosystems have become challenging subjects for world sustainability. Humans, animals, and other ocean habitats are primarily affected by the harmful changes in climate. Coastal ecosystems support biodiversity and a wide range of species that serve as habitats for many commercially important fish species and enhance human activities in coastal areas. By engaging in coastal outdoor activities, individuals can experience numerous physical and mental health benefits, foster environmental awareness. This study provided valuable insights into the importance of coastal outdoor activities and their potential to improve our quality of life. This study undertook a challenging subject where we graphically and econometrically analyze the relationship and linkages among coastal indicators with other climate-concerning factors. The study comprises the ordinary regression and comparative analysis among the four largest coastline countries in the world. The study took a sample from Canada, Indonesia, Norway, and the Russian Federation from 1990 to 2022. The data is selected on a convenient basis. Results declared that each country has its unique challenges and opportunities in mitigating adverse climate change and retaining a sustainable coastal ecosystem. The study surprisingly revealed that climate change insignificantly affects the coastal ecosystem in Indonesia and the Russian Federation while it inversely affects the coastal ecosystem in Canada and Norway, showed that climate change on average declines coastal production by 0.0041922 and 0.0261104 in Canada and Norway respectively. The detailed review is given in the results section; however, the pooling analysis proved that at the aggregate level, a one percent increase in climate change caused a 0.02266-tonne decline in coastal ecosystems in the four largest coastline nations. There is a need for policies tend to increase CAP activities by implementing practical marine protected areas. Furthermore, scientific research and monitoring will be beneficial in restoring coastal sustainability.

Cyclin A1 (CCNA1) inhibits osteoporosis by suppressing transforming growth factor-beta (TGF-beta) pathway in osteoblasts.

BACKGROUND: Osteoporosis is a genetic disease caused by the imbalance between osteoblast-led bone formation and osteoclast-induced bone resorption. However, further gene-related pathogenesis remains to be elucidated. METHODS: The aberrant expressed genes in osteoporosis was identified by analyzing the microarray profile GSE100609. Serum samples of patients with osteoporosis and normal group were collected, and the mRNA expression of candidate genes was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The mouse cranial osteoblast MC3T3-E1 cells were treated with dexamethasone (DEX) to mimic osteoporosis in vitro. Alizarin Red staining and alkaline phosphatase (ALP) staining methods were combined to measure matrix mineralization deposition of MC3T3-E1 cells. Meanwhile, the expression of osteogenesis related genes including alkaline phosphatase (ALP), osteocalcin (OCN), osteopontin (OPN), Osterix, and bone morphogenetic protein 2 (BMP2) were evaluated by qRT-PCR and western blotting methods. Then the effects of candidate genes on regulating impede bone loss caused by ovariectomy (OVX) in mice were studied. RESULTS: Cyclin A1 (CCNA1) was found to be significantly upregulated in serum of osteoporosis patients and the osteoporosis model cells, which was in line with the bioinformatic analysis. The osteogenic differentiation ability of MC3T3-E1 cells was inhibited by DEX treatment, which was manifested by decreased Alizarin Red staining intensity, ALP staining intensity, and expression levels of ALP, OCN, OPN, Osterix, and BMP2. The effects of CCNA1 inhibition on regulating osteogenesis were opposite to that of DEX. Then, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis demonstrated that genes negatively associated with CCNA1 were enriched in the TGF-beta signaling pathway. Inhibitor of TGF-beta signaling pathway partly reversed osteogenesis induced by suppressed CCNA1. Furthermore, suppressed CCNA1 relieved bone mass of OVX mice in vivo. CONCLUSION: Downregulation of CCNA1 could activate TGF-beta signaling pathway and promote bone formation, thus playing a role in treatment of osteoporosis.

Initial experience with 161 extraperitoneal laparoscopic radical cystectomy procedures: Comparison with transabdominal laparoscopic radical cystectomy.

OBJECTIVES: There is substantial concern about traditional transperitoneal laparoscopic radical cystectomy (TLRC) due to multiple postoperative complications. In contrast, extraperitoneal laparoscopic radical cystectomy (ELRC) appears to cause a lower rate of morbidity. The present study aimed to compare the efficacy of ELRC and TLRC for bladder cancer (BCa). METHODS: The clinical data of patients undergoing laparoscopic radical cystectomy for BCa from April 2018 to October 2021 were retrospectively analyzed, as ELRC and TLRC groups. The postoperative follow-up data of 275 patients were collected and the incidence of postoperative complications and other perioperative outcomes were compared between the two groups. RESULTS: Surgery was successfully completed in all patients without conversion to open surgery. There was no significant difference in the duration of cystectomy surgery (67.32 ± 23.53 vs 72.17 ± 25.72 min, p = 0.106), intraoperative blood loss (178.06 ± 110.4 vs. 174.56 ± 127.40 ml, p = 0.413), or the number of lymph node dissection (15.1 ± 5.7 vs. 14.5 ± 5.1, p = 0.380) between the two groups. The length of stay (11.6 ± 3.8 vs 14.7 ± 5.6 d, p < 0.001), time to resume food intake after surgery (2.3 ± 0.9 vs 3.0 ± 1.3 d, p < 0.001), and the incidence of ileus (p < 0.001) in the ELRC group were significantly lower than in the TLRC group. CONCLUSIONS: ELRC is a safe procedure that can reduce the incidence of postoperative complications, shorten postoperative hospital stay, reduce the duration of recovery of patients, and, therefore, should be promoted.

Anticonvulsant Activity of Bombyx batryticatus and Analysis of Bioactive Extracts Based on UHPLC-Q-TOF MS/MS and Molecular Networking.

Bombyx batryticatus (BB) is an anticonvulsant animal medicine in traditional Chinese medicine (TCM) and acts on the central nervous system. This research aimed to study the anticonvulsant effects of different polarity fractions of extracts from BB and to explore the components conferring anticonvulsant activity. Materials and methods: Crude extracts of BB at 20 g/kg were divided into different polarity fractions (petroleum ether, chloroform, ethyl acetate, water) and were administered to groups of mice before injecting pentylenetetrazol (PTZ) to induce convulsions. The animals were placed in chambers, and their behaviors were recorded for 30 min following the injection. Latency time, percent of protection, convulsion, convulsion rate, and convulsion score were determined for these mice. The compounds present in the different fractions were analyzed, and those from the fraction that conferred anticonvulsant activity were identified by high-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UHPLC-Q-TOF MS) and molecular networking (MN). The chloroform extract fractions (B-C) clearly increased the seizure latency time and protection percentage and decreased the convulsion percentage compared to the control group. The anticonvulsant effect of other extract fractions was not significant. Our study shows that the chloroform extract fractions (B-C) of BB have a significant anticonvulsant effect. We also identified 17 compounds including lumichrome, pheophorbide A, and episyringaresinol 4'-O-beta-d-glucopyranose that were found for the first time. The results of this study may lay the groundwork for studying compounds derived from Bombyx batryticatus and their anticonvulsant effect.

The Novel Compound Heterozygous Mutations of GAA Gene in Mainland Chinese Patient with Classic Infantile-Onset Pompe Disease.

Pompe disease (PD) is a rare and fatal neuromuscular disease, which is an autosomal recessive disorder. This is the first study to report a case of the compound heterozygous c.1822C>T and c.2297A>C mutations of the GAA gene in mainland Chinese patient, which led to the classic infantile-onset Pompe disease (IOPD) characterized by hypertrophic cardiomyopathy. This case highlights that the detection of GAA activity in peripheral blood by dried blood spot and GAA gene analysis can clarify the diagnosis of IOPD and provides the genetic counseling to those parents whose children have IOPD for giving birth in the future. Although PD is rare, and universal screening has not yet been established, we suggest that clinicians should consider the possibility of Pompe in the presence of hypertrophic cardiomyopathy.

Rs217727 polymorphism in H19 promotes cell apoptosis by regulating the expressions of H19 and the activation of its downstream signaling pathway.

BACKGROUND: The objective of the current study was to explore the role of H19 rs217727 polymorphism in the control of hepatocellular carcinoma (HCC). METHOD: The Student's t test, Cox regression, and Kaplan-Meier analyses were used to clarify whether the H19 rs217727 polymorphism played an important role in the development of HCC. Real-time polymerase chain reaction (PCR) and western-blot analysis were carried out to measure the levels of H19, microRNA (miR)-675, FAS-associated death domain (FADD), caspase-8, and caspase-3 among H19 CC, CT, and TT groups, as well as in cells transfected with H19/si-H19, or miR-675 mimic/inhibitor. The MTT assay, colony formation assay, and flow cytometry assay were performed to detect the effect of H19/miR-675 on cell viability, cell colony formation, and cell apoptosis. RESULT: T allele of H19 rs217727 polymorphism apparently increased the survival rate of patients with HCC. Meanwhile, H19 enhanced miR-675 expression but reduced the mRNA and protein levels of FADD, caspase-3, and caspase-8. The T allele of H19 rs217727 polymorphism apparently increased the apoptotic rate of HCC cells. Furthermore, FADD was a virtual target gene of miR-675 with a potential "hit" located in the 3'-untranslated region (UTR) of FADD, whereas H19 inhibited FADD expression via increasing the expression of miR-675. Moreover, H19 upregulated the expression of miR-675 whereas reducing the expression of FADD, caspase-3, and caspase-8. Finally, H19 and miR-675 promoted cell proliferation and cell colony formation but repressed cell apoptosis. CONCLUSION: In summary, the above findings demonstrated that the polymorphism of rs217727 in H19 was associated with HCC via the H19/miR-675/FADD/caspase-8/caspase-3/apoptosis signaling pathway.

Additive-Assisted Novel Dual-Salt Electrolyte Addresses Wide Temperature Operation of Lithium-Metal Batteries.

In this study, self-synthesized lithium trifluoro(perfluoro-tert-butyloxyl)borate (LiTFPFB) is combined with lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) to formulate a novel 1 m dual-salt electrolyte, which contains lithium difluorophosphate (LiPO2 F2 ) additive and dominant carbonate solvents with low melting point and high boiling point. The addition of LiPO2 F2 into this novel dual-salt electrolyte dramatically improves cycleability and rate capability of a LiNi0.5 Mn0.3 Co0.2 O2 /Li (NMC/Li) battery, ranging from -40 to 90 °C. The NMC/Li batteries adopt a Li-metal anode with low thickness of 100 µm (even 50 µm) and a moderately high cathode mass loading level of 10 mg cm-2 . For the first time, this paper provides valuable perspectives for developing practical lithium-metal batteries over a wide temperature range.

Genomic sequencing identifies novel Bacillus thuringiensis Vip1/Vip2 binary and Cry8 toxins that have high toxicity to Scarabaeoidea larvae.

The Bacillus thuringiensis strain HBF-18 (CGMCC 2070), which has previously been shown to encode the cry8Ga toxin gene, is active against both Holotrichia oblita and Holotrichia parallela. Recombinant Cry8Ga however is only weakly toxic to these insect pests suggesting the involvement of additional toxins in the native strain. We report that through the use of Illumina sequencing three additional, and novel, genes, namely vip1Ad1, vip2Ag1, and cry8-like, were identified in this strain. Although no protein corresponding to these genes could be identified by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis of the HBF-18 proteome, reverse transcription (RT)-PCR indicated that all three genes were transcribed in the native strain. The two vip genes were cloned and expressed and, as with other Vip1/2 toxins, appeared to function as a binary toxin and showed strong activity against H. oblita, H. parallela and Anomala corpulenta. This is the first report to demonstrate that the Vip1/Vip2 binary toxin is active against these Scarabaeoidea larvae. The cry8-like gene appeared to be a C-terminally truncated form of a typical cry8 gene and was not expressed in our usual recombinant Bt expression system. When however the missing C-terminal region was replaced with the corresponding sequence from cry8Ea, the resulting hybrid expressed well and the toxin was active against the three test insects.

Pressure-induced reversible phase transition in thiourea dioxide crystal.

The effect of high pressure on the crystal structure of thiourea dioxide has been investigated by Raman spectroscopy and angle-dispersive X-ray diffraction (ADXRD) in a diamond anvil cell up to 10.3 GPa. The marked changes in the Raman spectra at 3.7 GPa strongly indicated a structural phase transition associated with the distortions of hydrogen bonding. There were no further changes up to the maximum pressure of 10.3 GPa and the observed transition was completely reversible when the system was brought back to ambient pressure. This transition was further confirmed by the changes of ADXRD spectra. The high-pressure phase was indexed and refined to an orthorhombic structure with a possible space group Pbam. The results from the first-principles calculations suggested that this phase transition was mainly related to the changes of hydrogen-bonded networks in thiourea dioxide.

A genetically modified broad-spectrum strain of Bacillus thuringiensis toxic against Holotrichia parallela, Anomala corpulenta and Holotrichia oblita.

Cry8Ea1 from Bacillus thuringiensis strain Bt185 has insecticidal activity against Holotrichia parallela. Cry8Ca2 from strain HBF-1 is effective against Anomala corpulenta. Cry8Ga1 from strain HBF-18 is toxic to H. oblita. Given the need to broaden the spectrum of B. thuringiensis, a broad-spectrum coleopteran active strain of B. thuringiensis, BIOT185, engineered to express multiple cry genes, including cry8Ea1, cry8Fa1 and cry8Ca2, was created by homologous recombination introducing the cry8Ca2 into the B. thuringiensis strain Bt185 by Liu et al. (Appl Microbiol Biotechnol 87:243-249, 2010). To further broaden the spectrum, an engineered B. thuringiensis strain BIOT1858G was constructed by introducing the recombinant plasmid pSTK-8G containing cry8Ga1 into the engineered B. thuringiensis strain BIOT185. PCR and Southern blotting demonstrated that the cry8Ga1 gene was transferred to the novel strain BIOT1858G. SDS-PAGE and RT-PCR confirmed the normal expression and transcription of the cry8Ga1 gene in addition to the cry8Ea1, cry8Fa1 and cry8Ca2 genes. Bioassays of BIOT1858G indicated that the recombinant strain broadened the spectrum against not only H. parallela susceptible to the Cry8E protein and A. corpulenta susceptible to the Cry8C protein but also H. oblita susceptible to the Cry8G protein. The pesticide could also decrease the cost of production and field labor.

Effect of thoracolumbar fascia injury on reported outcomes after percutaneous vertebroplasty.

Purpose: Thoracolumbar fascia injury is often associated with poor early pain relief after percutaneous vertebroplasty (PVP). This study will evaluate the effects of thoracolumbar fascia injury on early pain relief and time to get out of bed after PVP. Methods: A total of 132 patients treated with PVP for osteoporotic vertebral compression fractures (OVCF) were included and divided into injured group (52 cases) and non-injured group (80 cases) according to the existence of thoracolumbar fascia injury. Before surgery, 1 day, 3 days, 1 week, 1 month, and 3 months after surgery, and at the last follow-up, the primary patient-reported outcome measures (PROMs) were the visual analogue scale (VAS) of pain while rolling over and standing, and the secondary PROMs was the Oswestry disability index (ODI). Meanwhile, the achieved rate of minimal clinically important differences (MCID) and patient acceptable symptom states (PASS) of the above measures in both groups was evaluated at the last follow-up. Results: Except for the postoperative 3 months and the last follow-up, there were statistically significant differences in VAS-standing and ODI between the two groups at other time points after surgery (P < 0.05), and the non-injured group was significantly better than the injured group. At the last follow-up, there was no statistically significant difference in the MCID and PASS achievement rates of the above measures between the two groups (P > 0.05). In addition, the proportion of patients who got out of bed 1 and 3 days after surgery in the non-injury group was significantly higher than that in the injury group (P = 0.000 for both). Conclusion: Thoracolumbar fascia injury significantly affected early pain relief and extended time of getting out of bed after PVP. Attention should be paid to preoperative evaluation of thoracolumbar fascial injury in order to better predict the postoperative efficacy of PVP.

Cultural moderation in sports impact: exploring sports-induced effects on educational progress, cognitive focus, and social development in Chinese higher education.

BACKGROUND: This research examines the nuanced challenges confronting Chinese university students within the dynamic milieu of Chinese education. The study comprehensively investigates factors encompassing educational progress, social development, cognitive focus, and Psychological Well-being (PWB), specifically emphasizing the role of sports participation. METHODS: To scrutinize the moderation-mediation nexus between cultural context and social development, a distribution of 500 questionnaires was administered to Chinese university students, yielding 413 responses, corresponding to an 82.6% response rate. Methodologically, this study employed moderation and mediation analyses, incorporating statistical techniques such as a principal component matrix, factor analysis, and hierarchical regression. FINDINGS: Prominent findings underscore the significant impact of age on educational progress, shaping the trajectory of academic advancement. Cumulative Grade Point Average (CGPA) emerges as a promising metric, establishing a link between academic performance and educational progress. Active involvement in sports and physical activities (PSPA) positively affects academic performance and study habits. Participation in sports teams and clubs (ISTC) enriches social development by nurturing interpersonal relationships, teamwork, and leadership skills. Sports activities (ESA) correlate with enhanced cognitive focus and improved psychological well-being. Significantly, the findings unveil a nuanced association between Perceived Social Development Through Sports (PSDTS) and educational progress. CONCLUSIONS: Cultural Context (CC) moderates PSDTS, Sport-induced Cognitive Focus (SICF), and PWB, influencing educational progress. This study emphasizes the need for enhanced support systems-academic guidance, awareness, sports programs, and cultural competence training-to advance student well-being and academic achievement in China, fostering an empowering educational environment for societal progress.

Identification, characterization and hypolipidemic effect of novel peptides in protein hydrolysate from Protaetia brevitarsis larvae.

The proteins were mainly derived from Protaetia brevitarsis larval extracts obtained using two empty intestine methods (traditional static method: TSM or salt immersion stress method: SISM) and extraction solvents (water: W or 50 % water-ethanol: W:E), and the proteins were used as objects to investigate the effect of emptying intestine methods on hypolipidemic peptides. The results revealed that the F-2 fractions of protein hydrolysate had stronger in vitro hypolipidemic activity, with the peptides obtained by SISM possessing a stronger cholesterol micelle solubility inhibition rate, especially in SISM-W:E-P. Moreover, a total of 106 peptides were tentatively identified, among which SISM identified more peptides with an amino acid number < 8. Meanwhile, five novel peptides (YPPFH, YPGFGK, KYPF, SPLPGPR and VPPP) exhibited good hypolipidemic activity in vitro and in vivo, among which YPPFH, VPPP and KYPF had strong inhibitory activities on pancreatic lipase (PL) and cholesteryl esterase (CE), and KYPF, SPLPGPR and VPPP could significantly reduce the TG content in Caenorhabditis elegans. Thus, P. brevitarsis can be developed as a naturally derived hypolipidemic component for the development and application in functional foods.

The Nexus of Sports-Based Development and Education of Mental Health and Physical Fitness.

Physical inactivity has increased globally, particularly in developed nations. A high proportion of the human population is unable to meet the physical activity recommendation of the World Health Organisation due to hypertension, metabolic syndrome, obesity, and other medical conditions. Non-communicable diseases and mental health problems are becoming more prevalent, particularly in low and middle-income nations. This study aimed to determine the effectivenessof a mentorship programmeon university students' mental health and physical fitness. The intervention comprised the effects of sports-based development and education on physical fitness and mental health. A total of 196 and 234 students from two universities were randomly assigned to the intervention and control groups, respectively. The primary outcomes were engagement in physical activities (number of push-ups for 1 min, the strength of hand grip (kg), and the Jump test while standing (cm)), body fat proportion and psychological resilience, self-efficacy, and relationship with family and schoolmates. Participants in the control group had access to a web-based health education game, whereas the intervention group wassubjected to intensive interventional activities for one month based on the eight principles of the National Research Council and Institute of Medicine. Data were analysed using Analysis of Variance (ANOVA) to compare the physical and mental components between the intervention and control groups. Relative to baseline, all the physical health components (push-ups, sit-ups, and jump tests), psychological resilience, relationship with family members, and self-efficacy increased significantly in the intervention compared to the control group. Body fat composition was significantly reduced in the intervention when compared tothe control group. In conclusion, the mentorship programme effectively improved the participants' physical and psychological health and could be developed further for application in a larger population.

Brain activation of the PFC during dual-task walking in stroke patients: A systematic review and meta-analysis of functional near-infrared spectroscopy studies.

Background: Dual-task walking is a good paradigm to measure the walking ability of stroke patients in daily life. It allows for a better observation of brain activation under dual-task walking to assess the impact of the different tasks on the patient when combining with functional near-infrared spectroscopy (fNIRS). This review aims to summarize the cortical change of the prefrontal cortex (PFC) detected in single-task and dual-task walking in stroke patients. Methods: Six databases (Medline, Embase, PubMed, Web of Science, CINAHL, and Cochrane Library) were systematically searched for relevant studies, from inception to August 2022. Studies that measured the brain activation of single-task and dual-task walking in stroke patients were included. The main outcome of the study was PFC activity measured using fNIRS. In addition, a subgroup analysis was also performed for study characteristics based on HbO to analyze the different effects of disease duration and the type of dual task. Results: Ten articles were included in the final review, and nine articles were included in the quantitative meta-analysis. The primary analysis showed more significant PFC activation in stroke patients performing dual-task walking than single-task walking (SMD = 0.340, P = 0.02, I 2 = 7.853%, 95% CI = 0.054-0.626). The secondary analysis showed a significant difference in PFC activation when performing dual-task walking and single-task walking in chronic patients (SMD = 0.369, P = 0.038, I 2 = 13.692%, 95% CI = 0.020-0.717), but not in subacute patients (SMD = 0.203, P = 0.419, I 2 = 0%, 95% CI = -0.289-0.696). In addition, performing walking combining serial subtraction (SMD = 0.516, P < 0.001, I 2 = 0%, 95% CI = 0.239-0.794), obstacle crossing (SMD = 0.564, P = 0.002, I 2 = 0%, 95% CI = 0.205-0.903), or a verbal task (SMD = 0.654, P = 0.009, I 2 = 0%, 95% CI = 0.164-1.137) had more PFC activation than single-task walking, while performing the n-back task did not show significant differentiation (SMD = 0.203, P = 0.419, I 2 = 0%, 95% CI = -0.289-0.696). Conclusions: Different dual-task paradigms produce different levels of dual-task interference in stroke patients with different disease durations, and it is important to choose the matching dual-task type in relation to the walking ability and cognitive ability of the patient, in order to better improve the assessment and training effects.

A novel extraperitoneal approach exploration for the treatment of urachal mass: a retrospective observational single-center study.

BACKGROUND: To explore the extraperitoneal laparoscopic urachal mass excision technique and its safety and efficacy in treating urachal mass. METHODS: Baseline characteristics were collected from patients who underwent surgery to diagnose a urachal cyst or abscess in our hospital between January 2020 and August 2021. The full-length of the urachus and part of the top bladder wall were completely removed through the extraperitoneal approach. Patient outcomes were collected to evaluate surgical safety and efficacy, including operation time, intraoperative blood loss, drainage tube removal time, length of stay (LOS), and postoperative complications. RESULTS: All 20 surgeries were successfully performed laparoscopically, and no case was converted to open surgery. The mean body mass index of the patients was 24.6 ± 2.2. The mean patient age was 49.3 ± 8.7 years. The mean size of the cysts was 3.0 ± 0.4 cm. The mean operation time was 56.3 ± 12.0 min. The mean intraoperative blood loss was 28.0 ± 6.4 mL. The mean drainage tube removal time was 3.0 ± 0.5 days. The mean LOS was 5.2 ± 0.4 days. The mean follow-up was 13.4 ± 2.1 months. No postoperative complications were observed during the follow-up period. The short-term follow-up and small patient cohort limited our outcome evaluation. CONCLUSION: Our results indicated that the extraperitoneal laparoscopic approach was a safe and effective method to treat urachal mass. Given the limitations of the study, further multiple and larger sample-sized trials are required to confirm our findings.

Characterization of bioactives and in vitro biological activity from Protaetia brevitarsis larval extracts obtained by different pretreatment extractions.

Intestinal contents affect the characterization of edible insect bioactive compounds. Two empty intestine methods, namely, traditional static method (TSM) or salt immersion stress method (SISM), associated with extraction solvents water (W), 50 % water-ethanol (W:E) or 100 % ethanol (E), were used to obtain six Protaetia brevitarsis larval extracts. The total flavonoid content (TFC) in the W:E extracts was significantly higher than that in the W and E extracts, with TSM-W:E the highest (p < 0.05). The relative contents of 132 bioactive compounds, especially p-hydroxyphenylacetic acid, citric acid, and dehydroepiandrosterone, were different between TSM-W and SISM-W. TSM-W:E had significantly higher 2,2-diphenyl-1-picrylhydroxy· (DPPH) scavenging and pancreatic lipase (PL) inhibitory activity than SISM-W:E (p < 0.05). DPPH scavenging and PL inhibitory activities were highly correlated with TFC and carbohydrates, respectively. Thus, bioactive compounds in P. brevitarsis extracts can be obtained selectively using pretreatment methods, which might be beneficial for high-value utilization of P. brevitarsis.

Initial Experience With Extraperitoneal Laparoscopic Radical Cystectomy With Pelvic Organ-Preserving and Orthotopic Neobladder Techniques for Bladder Cancer in Female Patients.

OBJECTIVE: To present the extraperitoneal laparoscopic radical cystectomy (ELRC) technique, and initial outcomes of organ-preserving and orthotopic neobladder (ONB) techniques for bladder cancer in selected females. MATERIALS AND METHODS: Data including patient characteristics, operative time, blood loss, transfusion rate, length of hospital stay, and pathologic outcomes, as well as 30- and 90-day complications were collected between April 2018 and May 2021 from females who underwent ONB after ELRC. Regular follow-up focused on patients' oncological and functional outcomes, and postoperative sexual function status was assessed using the Female Sexual Function Index (FSFI). RESULTS: Eleven females with a mean age of 53 years who underwent ELRC with pelvic organ-preservation and ONB were analyzed retrospectively. All procedures were completed successfully. The mean operative time was 264.82 ± 33.81 min, and the average intraoperative blood loss was 128 ± 18.19 mL. All patients had negative pathological margins and no lymph node metastases. The average hospital stay was 10.72 days. The single J ureteral stent and catheter were usually removed 3-4 weeks after the procedure. The FIFS assessment of postoperative sexual function showed that the patients were relatively satisfied. CONCLUSION: ELRC with pelvic organ preservation and ONB technology was a safe and feasible surgical strategy for the selected female patients. Preserving organs and vascular nerve bundles seemed to be safe in oncological and produced encouraging functional results. Further rigorous prospective studies with more patients and long-term follow-up data are needed to assess the oncologic and functional results.

Differential regulation of jasmonate responses in multiple jaz mutants.

The phytohormones jasmonates (JAs) regulate diverse aspects of plant growth and defense responses. The JA-ZIM domain (JAZ) family of repressors are targeted by the JA receptor Coronatine Insensitive 1 for ubiquitination and subsequent degradation via the 26S proteasome. We previously investigated the functions of JAZs in JA responses by analyzing jaz mutants of the phylogenetic group I (jaz1/2/5/6), group II/III (jaz10/11/12), group IV/V (jaz3/4/7/9 and jaz3/4/7/8/9), and their high-order mutant jaz1/2/3/4/5/6/7/9/10/11/12. Here, we examined JA-regulated root growth, apical hook curvature, flowering time, and defense against the insect Spodoptera exigua in the intermediate jaz mutants jaz1/2/5/6/10/11/12, jaz1/2/3/4/5/6/7/9, and jaz3/4/7/8/9/10/11/12. This study shows that these jaz mutants differentially affect JA responses, suggesting the complexity of JA pathway in these multiple jaz mutants.

Correlation of TET-2 Levels with Disease Evaluation in AMI Patients.

Objective: To investigate the expression levels of Ten-Eleven Translocation-2 (TET-2) in patients with acute myocardial infarction (AMI) and correlations of TET-2 levels with disease severity. Methods: A total of 150 patients with confirmed AMI were included in this study. According to the number of coronary artery lesions, the patients were divided into a single lesion group, two lesion group, and three lesion group. According to the Gensini scores, these patients were also assigned into three groups: the low-risk group, middle-risk group, and high-risk group. 150 patients without AMI confirmed by coronary angiography were included in the control group in the same period. TET-2 and cardiac troponin T (cTNT) levels were detected by ELISA analysis and compared among different groups. Pearson's correlation analysis was used to evaluate the correlations of TET-2 levels and cTNT levels/Gensini scores. The levels of TET-2 in AMI patients increased remarkably with the increase of disease severity. Patients in the single lesion group or low-risk group had the lowest levels of TET-2. Pearson correlation analysis indicated that TET-2 levels were positively associated with cTNT levels and Gensini scores, respectively (all P < 0.001). Conclusion: The levels of TET-2 were upregulated in AMI patients and positively correlated with cTNT levels or Gensini scores, suggesting that the examination of TET-2 expression levels could be exploited for predicting the disease severity.
