Background: Oxidative stress-induced cardiomyocytes apoptosis is a key pathological process inischemic heart disease. Glutathione reductase (GR) reduces glutathione disulfide to glutathione (GSH) toalleviate oxidative stress. Ginsenoside Rb1 (GRb1) prevents the apoptosis of cardiomyocytes; however,the role of GR in this process is unclear. Therefore, the effects of GRb1 on GR were investigated in thisstudy. Methods: The antiapoptotic effects of GRb1 were evaluated in H9C2 cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, annexin V/propidium iodide staining, and Western blotting. Theantioxidative effects were measured by a reactive oxygen species assay, and GSH levels and GR activitywere examined in the presence and absence of the GR inhibitor 1,3-bis-(2-chloroethyl)-1-nitrosourea. Molecular docking and molecular dynamics simulations were used to investigate the binding of GRb1 toGR. The direct influence of GRb1 on GR was confirmed by recombinant human GR protein. Results: GRb1 pretreatment caused dose-dependent inhibition of tert-butyl hydroperoxide-induced cellapoptosis, at a level comparable to that of the positive control N-acetyl-L-cysteine. The binding energybetween GRb1 and GR was positive ( 6.426 kcal/mol), and the binding was stable. GRb1 significantlyreduced reactive oxygen species production and increased GSH level and GR activity without altering GRprotein expression in H9C2 cells. Moreover, GRb1 enhanced the recombinant human GR protein activityin vitro, with a half-maximal effective concentration of z2.317 mM. Conversely, 1,3-bis-(2-chloroethyl)-1-nitrosourea co-treatment significantly abolished the GRb1’s apoptotic and antioxidative effects of GRb1in H9C2 cells. Conclusion: GRb1 is a potential natural GR agonist that protects against oxidative stresseinducedapoptosis of H9C2 cells.

Survival Analysis of Oral Squamous Cell Carcinoma in a Subgroup of Young Patients
Fan, Yi,Zheng, Lei,Mao, Ming-Hui,Huang, Ming-Wei,Liu, Shu-Ming,Zhang, Jie,Li, Sheng-Lin,Zheng, Lei,Zhang, Jian-Guo Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.20
Oral squamous cell carcinoma (OSCC) is predominantly a disease of middle-aged men with long-term exposure to tobacco and alcohol. An increasing trend has been reported at a younger age worldwide. Clinical records of 100 patients under the age of 45 years treated specifically for oral cavity SCC in our hospital during a 10-year period were retrospectively analyzed to calculate the survival rates. An obvious male predominance coincided with smoking trend among Chinese young individuals and female patients were more likely to have no traditional risk factors such as smoking or drinking. The 5-year overall survival rate and disease-free survival rate were 61.0% and 75.5%, respectively, consistent with other published series over the decade showing a relatively better survival among the young. No significant differences clearly correlated with outcome when comparing non-smokers non-drinkers to ever-smokers and ever drinkers (P>0.05). Overall survival rate and disease free survival rate was found to be significantly higher in patients with early-stage disease than with advanced stage disease (P=0.001, P=0.009 respectively). The strong influence of clinical stage on prognosis emphasizes the importance of early diagnosis and treatment of oral malignancies for this unique clinical subgroup.

Eco-friendly Polypyrrole-coated Cocozelle Composites for Supercapacitor Application
Hui Ji,Chuanjie Zhang,Weida Rao,Bin Guo,Lingling Fan,Zikui Bai,Haifeng Bao,Jie Xu 한국섬유공학회 2020 Fibers and polymers Vol.21 No.6
Cocozelle is essentially consisted of hemicellulose and lignin with a hierarchically porous structure. Herein,cocozelle slices after freeze-drying were employed as green substrates to support the growth of polypyrrole (PPy) via a facileoxidative polymerization approach. The cocozelle surface was densely covered with sheet-like PPy due to the hydrogenbonding between PPy and cocozelle. The PPy/cocozelle composites could be facilely utilized as supercapacitor electrodes,which showed a high specific capacitance of 1108 F g-1 with an energy density of 70.5 Wh kg-1 and a power density of398 W kg-1 at a charge/discharge current density of 0.8 mA cm-2 as well as desirable cycling life with a capacitance retentionrate of 76.9 % after 1000 cycles. Moreover, 95.3 % of the initial specific capacitance obtained at 0.2 mA cm-2 could bereached as the current density increased to 1.6 mA cm-2. These results demonstrate that cocozelle could be used as a superioralternative biomass-derived substrate for the developments of eco-friendly and renewable energy storage devices.

Query Aggregation in Wireless Sensor Networks
Min Meng,Jie Yang,Hui Xu,Byeong-Soo Jeong,Young-Koo Lee,Sungyoung Lee,Xiaobo Fan 보안공학연구지원센터 2008 International Journal of Multimedia and Ubiquitous Vol.3 No.1
Wireless sensor networks have been used more and more widely with the developments of related techniques in telecommunication and computer sciences. While sensor nodes in wireless sensor networks have very limited memory spaces and power. In this paper, we propose a new query aggregation method to preprocess the query predicates. The size of the relational table can be further reduced using the aggregated query predicates. The reduced relational table can be stored on the sensor nodes. This may cause false positive but definitely no false negative. When the required data are sent back to the sink, we can do join operation between the real query predicate and the relational table again, and eliminate the redundant data.

Novel CoFe2O4/MIL-100(Fe) (CFO/MIL-100(Fe)) core/shell nanofibers were prepared by successive ionic layeradsorption and reaction (SILAR) assembly of MIL-100(Fe) on electrospun CoFe2O4 nanofibers. The MIL-100(Fe) shellswere constructed on the dispersed CoFe2O4 fiber surface with high uniformity, homogeneous thickness and high stability. Due to the inherent porosity of MIL-100(Fe), a higher specific surface area of 225.77 m2/g is achieved for the CFO/MIL-100(Fe)-10 sample. The formed CFO/MIL-100(Fe) catalysts exhibit high catalytic activity towards degradation of rhodamineB (RhB) under visible light irradiation. The photocatalytic activity remains above 77 % within 60 min illumination after fourcycles. Due to the simple synthetic method, highly uniform structure, strong magnetic recoverable, as well as goodphotocatalytic performance, the obtained CFO/MIL-100(Fe) core/shell nanofibers could be promising photocatalysts forpractical application.

Background: Advanced pancreatic cancer (APC) is a fatal disease with limited treatment options. This study aims to evaluate the effectiveness and safety of different Chinese herbal injections (CHIs) as adjuvants for radiotherapy (RT) in APC and compare their treatment potentials using network meta-analysis. Methods: We systematically searched three English and four Chinese databases for randomized controlled trials (RCTs) from inception to July 25, 2023. The primary outcome was the objective response rate (ORR). Secondary outcomes included Karnofsky performance status (KPS) score, overall survival (OS), and adverse events (AEs). The treatment potentials of different CHIs were ranked using the surface under the cumulative ranking curve (SUCRA). The Cochrane RoB 2 tool and CINeMA were used for quality assessment and evidence grading. Results: Eighteen RCTs involving 1199 patients were included. Five CHIs were evaluated. Compound Kushen injection (CKI) combined with RT significantly improved ORR compared to RT alone (RR 1.49, 95 % CrI 1.21–1.86). Kanglaite (KLT) plus RT (RR 1.58, 95 % CrI 1.20–2.16) and CKI plus RT (RR 1.49, 95 % CrI 1.16–1.95) were associated with improved KPS score compared to radiation monotherapy, with KLT+RT being the highest rank (SUCRA 72.28 %). Regarding AEs, CKI plus RT was the most favorable in reducing the incidence of leukopenia (SUCRA 90.37 %) and nausea/vomiting (SUCRA 85.79 %). Conclusions: CKI may be the optimal choice of CHIs to combine with RT for APC as it may improve clinical response, quality of life, and reduce AEs. High-quality trials are necessary to establish a robust body of evidence. Protocol registration: PROSPERO, CRD42023396828.

Purpose: This study evaluated the value of contrast-enhanced ultrasonography (CEUS) in the ultrasound-guided microwave ablation (MWA) treatment of symptomatic focal uterine adenomyosis.Methods: This retrospective study was conducted between March 2020 and January 2023, enrolling 52 patients with symptomatic focal uterine adenomyosis who had undergone MWA. All patients were examined with CEUS before and after MWA. The non-perfused volume (NPV) was compared between CEUS and dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) following ablation. Therapeutic efficacy and safety were evaluated at 3-, 6-, and 12-month follow-ups. Additionally, this study explored the correlations between pre-treatment CEUS features and a volume reduction ratio indicating sufficient ablation, defined as 50% or more at the 3-month follow-up.Results: No significant differences in NPV were noted between CEUS and DCE-MRI immediately after MWA and during follow-up (all P>0.05). At the 3-month follow-up, the median VRRs for the uterus and adenomyosis were 33.2% and 63.9%, respectively. Sufficient ablation was achieved in 69.2% (36/52) of adenomyosis cases, while partial ablation was observed in the remaining 30.8% (16/52). The identification of non-enhancing areas on pre-treatment CEUS was associated with sufficient ablation (P=0.016). At the 12-month follow-up, significant decreases were observed in both the uterine and adenomyosis volumes (all P<0.001). Dysmenorrhea and menorrhagia were significantly alleviated at 12 months, and no major complications were encountered.Conclusion: CEUS can be used to evaluate the ablation zone of focal adenomyosis that has been treated with MWA, similarly to DCE-MRI. The identification of non-enhancing areas on pretreatment CEUS indicates satisfactory treatment outcomes.
