Article Trabectedin Induces Synthetic Lethality via the p53-Dependent Apoptotic Pathway in Ovarian Cancer Cells Without BRCA Mutations When Used in Combination with Niraparib This study investigated whether combining niraparib and trabectedin in BRCA-proficient epithelial ovarian cancer induces deficiencies in ssDNA break repair and dsDNA homologous recombination, leading to synthetic lethality. A2780 and SKOV3 ovarian cancer cell lines were treated with niraparib and trabectedin. Cell viability was assessed using CCK-8 assays, while RT-qPCR and Western blot analyzed the expression of DNA repair and apoptosis-related genes. Apoptosis was evaluated via Annexin V/PI assays. The combination therapy exhibited a synergistic effect on A2780 cells but not on SKOV3 cells. Treatment reduced BRCA1, BRCA2, RAD51, PARP1, and PARP2 expression, indicating impaired DNA repair. gamma-H2AX levels increased, suggesting DNA damage. The therapy also upregulated p53, PUMA, NOXA, BAX, BAK, and p21, promoting p53-mediated apoptosis and cell cycle arrest. Apoptosis induction was confirmed via Annexin V/PI assays. Silencing p53 with siRNA abolished all synergistic effects in A2780 cells. Niraparib and trabectedin combination therapy impairs DNA repair in BRCA-proficient ovarian cancer, leading to synthetic lethality through p53-dependent apoptosis.

Article Trichostatin A-Induced Epigenetic Modifications and Their Influence on the Development of Porcine Cloned Embryos Derived from Bone Marrow-Mesenchymal Stem Cells Abnormal epigenetic reprogramming of nuclear-transferred (NT) embryos leads to the limited efficiency of producing cloned animals. Trichostatin A (TSA), a histone deacetylase inhibitor, improves NT embryo development, but its role in histone acetylation in porcine embryos cloned with mesenchymal stem cells (MSCs) is not fully understood. This study aimed to compare the effects of TSA on embryo development, histone acetylation patterns, and key epigenetic-related genes between in vitro fertilization (IVF), NT-MSC, and 40 nM TSA-treated NT-MSC (T-NT-MSC). The results demonstrated an increase in the blastocyst rate from 13.7% to 32.5% in the T-NT-MSC, and the transcription levels of CDX2, NANOG, and IGF2R were significantly elevated in T-NT-MSC compared to NT-MSC. TSA treatment also led to increased fluorescence intensity of acH3K9 and acH3K18 during early embryo development but did not differ in acH4K12 levels. The expression of epigenetic-related genes (HDAC1, HDAC2, CBP, p300, DNMT3a, and DNMT1) in early pre-implantation embryos followed a pattern similar to IVF embryos. In conclusion, TSA treatment improves the in vitro development of porcine embryos cloned with MSCs by increasing histone acetylation, modifying chromatin structure, and enhancing the expression of key genes, resulting in profiles similar to those of IVF embryos.

Article Two-step polymerization for tailored donor-acceptor interactions driving efficient hydrogen evolution in visible-light photocatalysts The development of materials for organic solar cells has made significant strides through the strategic combination of diverse donor structures with acceptor units in polymer backbones. In contrast, semiconducting polymers for photocatalytic hydrogen evolution have primarily focused on acceptor moieties, with limited exploration of donor contributions, primarily owing to the emphasis on designing active sites for proton reduction in inorganic catalysts. To investigate the impact of highly electron-donating moieties on photocatalytic performance, we designed and synthesized benzothiadiazole (BT)-based polymers with randomly incorporated benzodithiophene (BDT) and fluorene units via a streamlined one-pot Stille-Suzuki two-step polymerization. Comprehensive molecular characterization and optical spectroscopic analyses confirmed the successful synthesis of the target polymers. Photocatalytic hydrogen evolution studies, supported by photophysical and spectroscopic investigations, demonstrated that optimizing the proportion of BDT units in the polymer backbone enhances hydrogen evolution rates significantly. Additionally, comparative analyses further highlighted the distinct differences in the photocatalytic efficiency between the BDT and fluorene donor units, providing critical insights into their functional roles. This work underscores the potential of advancing polymer photocatalysts by fine-tuning donor-acceptor interactions through optimization of donor moiety composition, offering a robust framework for achieving superior photocatalytic performance. © 2025 RSC.

Article Transcriptome Analysis of HNSCC by Aggregatibacter actinomycetemcomitans Extracellular Vesicles ObjectivesThe role of extracellular vesicles (EVs), also known as outer membrane vesicles (OMVs), secreted by oral bacteria in the progression of head and neck squamous cell carcinomas (HNSCCs), is largely unexplored. This study aimed to investigate the influence of bacterial EVs, specifically those derived from Aggregatibacter actinomycetemcomitans (Aa), on the progression of HNSCC.Materials and MethodsFaDu and UMSCC1 cell lines were treated with Aa-derived EVs, and oncogenic activities were assessed. Comprehensive cellular and RNA-sequencing transcriptome analyses were conducted to assess the impact of these EVs on cell cycle progression and gene expression.ResultsOur findings reveal that Aa-derived EVs accelerate cell cycle progression through the S and G2 phases and enhance invasion in HNSCC cell lines. RNA-sequencing analysis showed that Aa-derived EVs exert a more significant effect on general transcript expression than on microRNA profiles, except for miR-146a, which is recognized as a key factor in both carcinogenesis and immune modulation.ConclusionsBacterial EVs, particularly from periodontal pathogens like Aa, are significant modulators within the oral cancer environment, potentially affecting cellular behavior and gene expression profiles. This study highlights the complex relationship between periodontal health and oral carcinogenesis, emphasizing the significant role of bacterial EVs in HNSCC progression.

Article On the degenerate negative λ-binomial and Poisson random variables from degenerate special polynomials In this paper, we investigate the theory and applications of negative lambda-binomial random variable with parameter $(r,p)$(r,p) and Poisson random variable with parameter $\alpha $alpha. In particular, we show that the expectation of rising factorial sequences or degenerate rising factorial sequences of negative lambda-binomial random variables or Poisson random variables are strongly related to Lah numbers, modified degenerate Lah-Bell polynomials, the Stirling numbers of the first kind and Bell polynomials.

Article Some identities of Fubini numbers related to special numbers In this paper, we examine the interconnections between Fubini numbers and a range of recently defined special numbers, including the Lah-Bell numbers, the Changhee numbers, and the Dahee numbers, along with several other established special numbers. We explore these relationships by analysing the generating functions associated with these numbers, which enables us to establish diverse formulae for Fubini numbers in relation to other special numbers. Additionally, we uncover new properties of Fubini numbers through this investigation. Furthermore, by employing formal power series of generating functions, we establish general identities for special numbers, thereby extending our understanding of their properties and relationships. Finally, we study the interconnections of the five special functions by observing the shape of functions.

Article Synthesis and X-ray structure analysis of cytotoxic 2-picolylamino-type HfⁱV-bis-chelated complexes Eight novel heteroleptic HfIV complexes containing differently substituted 2-picolylamino-bis-phenolate and 2,6-dipicolinic acid (Dipic) groups as chelating ligands were synthesized and characterized with yields higher than 80%. These [ONON] type HfIV complexes have good aqueous stability and potent anti-tumor activity against HeLa S3 (human cervical adenocarcinoma) and Hep G2 (human derived hepatoma) cells. In particular, the complexes demonstrated selective inhibitory activity against Hep G2 cells. The IC50 value of the most cytotoxic complex [L1HfIVDipic4-Cl] (0.9 +/- 0.4 mu M) was ten-fold higher than that of cisplatin (11.2 +/- 2.1 mu M) on Hep G2 cells, being the most cytotoxic anti-tumor HfIV complex to date. Furthermore, [L1HfIVDipic4-Cl] could inhibit tumor cell migration, induce reactive oxygen species generation (particularly HO center dot), loss of mitochondrial membrane potential and almost exclusive early apoptosis in HeLa S3 cells. [L1HfIVDipic4-Cl] exhibited rapid cellular uptake by HeLa S3 cells, and when in aqueous media, these HfIV complexes slowly hydrolyzed, releasing non-toxic phenolato ligands as the product of hydrolysis. Overall, these rare earth complexes, particularly [L1HfIVDipic4-Cl], show promising potential as novel anticancer agents with significant efficacy against human liver cancer cells and favorable selectivity profiles for further therapeutic development.

Article Aspalathin, a Primary Rooibos Flavonoid, Alleviates Mast Cell-Mediated Allergic Inflammation by the Inhibition of FcεRI Signaling Pathway Mast cells are primary cells initiating allergic inflammation by the release of various allergic mediators, such as histamine and pro-inflammatory cytokines. Aspalathin (ASP) is the predominant flavonoid found exclusively in rooibos, an herb that has been traditionally used in allergy relief therapy. In the present study, we investigated the beneficial effects of ASP on mast cell-mediated allergic inflammation. For in vivo study, two well-known mast cell-mediated local and systemic allergic inflammation mouse models were used: passive cutaneous anaphylaxis (PCA) and active systemic anaphylaxis mouse models (ASA). Oral administration of ASP dose-dependently suppressed immunoglobulin (Ig)E-mediated PCA responses evidenced by Evans blue extravasation, ear thickening, and mast cell degranulation. ASP also significantly mitigated ovalbumin-induced ASA responses, including hypothermia, histamine secretion, and the production of IgE and interleukin-4. Notably, ASP was more effective in suppressing allergic inflammation than nothofagin, another prominent flavonoid known as an anti-allergic component of rooibos. The regulatory mechanism of mast cell activation by ASP was clarified using mast cell line and primary cultured mast cells (RBL-2H3 and mouse bone marrow-derived mast cells). ASP reduced IgE-stimulated mast cells degranulation and intracellular calcium influx by the inhibition of Fc epsilon RI signaling pathway (Lyn, Fyn, and Syk). Moreover, ASP reduced pro-inflammatory cytokine expressions by inhibiting two major transcription factors, nuclear factor of activated T cells and nuclear factor-kappa B. Collectively, we proposed that ASP could be a potential therapeutic candidate for the treatment of mast cell-mediated allergic inflammatory diseases.

Article Depth-Customizable 3D Electrode Array for Recording Functional Connectivity in the Brain Understanding neural activity across multiple brain regions, especially in three dimensions, is essential for advancing neuroscience research. However, traditional 3D electrode arrays are often restricted to fixed depths, limiting their ability to probe complex brain structures. In this study, a depth-customizable, flexible 3D multi-shank electrode array that produces precise neural recordings at various brain depths is developed. Integrating 2D flexible electrode arrays with a modular supporting board allowed the insertion depth to be easily adjusted without re-fabrication. In vivo experiments produce successful recordings from the motor cortex, somatosensory cortex, and deep structures such as the substantia nigra. Functional connectivity analysis also reveals strong correlations between the substantia nigra and motor cortex, confirming that the developed array can be used to accurately assess neural network dynamics in 3D space. Due to its greater experimental flexibility, the depth-customizable 3D electrode array developed in this study represents a versatile and cost-effective tool for assessing functional connectivity across the entire brain. © 2025 The Author(s).

Article Independent Association Between Frailty and Fear of Falling in Older Adults After Hip Fracture Surgery: A Cross-Sectional Study Using a Secondary Analysis Purpose: This study aimed to investigate the independent association between the fear of falling (FOF) and frailty in Korean older adults after hip fracture surgery.Methods: The study included 149 participants. Participants were asked to provide general characteristics and complete walking speed, grip strength, frailty, and Short Falls Efficacy Scale-International assessments. A binary logistic regression model was used to investigate the independent association of the FOF with frailty.Results: Among the participants, 49% were found to be prefrail and 24.8% were frail. Additionally, 86.5% reported a moderate to severe FOF. Participants with a FOF were 1.23 times more likely to be frail, and those aged 85 years and older were 13.25 times more likely to be frail.Conclusion: This study's findings serve as a basis for developing and applying interventions to reduce frailty in older adults after hip fracture surgery. These interventions should consider the oldest-old (>= 85 years) age group when they are designed.

Article Navigating Disparities: An In-depth Analysis of Perceived Competency Importance and Training Discrepancies in Clinical Placements Among Students and Clinical Nurses Purpose: This study investigated the perceived importance and training of competencies during nursing clinical placements by examining the perspectives of nursing students and clinical nurses. Methods: We conducted a cross-sectional study using an online survey of 351 nursing students and 247 clinical nurses. We utilized the Borich needs assessment model to identify the perceived importance and training of competencies during clinical placement. Students and nurses rated their perceived importance and training levels on 32 competency items regarding direct nursing care, indirect nursing care, decision-making and problem-solving, attitude, and nursing professionalism. Results: Students and clinical nurses identified nursing handovers, nursing records, crisis coping abilities, clinical problem identification, clinical decision-making, and priority setting in nursing as competencies of greater importance and with more significant discrepancies from training during clinical placements (Quadrant I in the locus for focus model). Clinical nurses reported examination, skin integrity management, and communication with medical staff as having higher importance and greater discrepancies from training (Quadrant I). In contrast, students recognized them as having lower importance and higher discrepancies (Quadrant II). For students, the perceived importance of all competence domains was significantly associated with the corresponding training (Spearman's rho 1/4 .30-.56, p < .01). For clinical nurses, only the perceived importance of nursing professionalism was associated with all training domains (Spearman's rho z .14.20, p < .05). Conclusion: The disparities between students' and nurses' perceptions of the importance and training of competencies during clinical placements highlight the need to modify the clinical nursing education system.

Article Viable Approach of Tuning Oxide Semiconductor Thin Films in Solution-Processed Heterojunction Thin Films Transistors for Both Higher Performances and Stability Metal-oxide thin-film transistors (TFTs) have garnered much attention because of their advantages such as high transparency, low leakage current, and low processing temperature. However, there is a need to continuously improve their mobility and bias stability for application to next-generation advanced electronics. In this study, the thickness of bilayer semiconductors is finely controlled to enhance the charge transport characteristics and bias stability in solution-processed heterojunction oxide TFTs. The thicknesses of the top and bottom layers in the bilayer are individually adjusted by controlling solution molarity. The introduction of a bilayer channel improved the electrical performance of oxide TFTs via effective charge transport. However, trap-limited conduction becomes dominant in the bilayer with an excessively thick top layer, thereby leading to a significant reduction in mobility and positive bias stability. Meanwhile, although increasing the bottom layer thickness contributes to improved mobility and reliability, it causes a serious negative shift in threshold voltage (VTH). TFTs with an optimized bilayer structure show high mobility at a VTH close to 0 V and have particularly excellent positive bias stress stability. This study on bilayer channel thickness will be beneficial for developing advanced transistors with optimized bilayer or multilayer channels. Bilayer-channel oxide TFTs are fabricated. The top and bottom active layer characteristics are designed by controlling the semiconductor thickness. Top active layer characteristics affect electron transport and stability in bilayer-channel TFTs. An optimized heterostructure channel leads to effective electron transport and outstanding bias stability. image Eun, Jun-Su; Lee, Jinuk; Na, Jeong-Hyeon; Park, Jun-Hyeong; Park, Won; Feng, Junhao; Seo, Kyung-Ho; Jang, Jaewon; Kang, In Man; Kim, Do-Kyung; Bae, Jin-Hyuk Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu 702701, South Korea; LG Display, Paju 10845, South Korea 58493099200; 58487758300; 57192006339; 57454302100; 58494046100; 57905127500; 59299567400; 57194107504; 7203062678; 57984042900; 35326180700 kdk7362@knu.ac.kr; jhbae@ee.knu.ac.kr; ADVANCED ELECTRONIC MATERIALS ADV ELECTRON MATER 2199-160X 11 2 SCIE MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED 2024 5.3 22.7 2.3 2025-05-07 2 1 bilayer structure; charge transport characteristics; oxide semiconductors; positive bias stability; semiconductor thickness control; thin-film transistors ACTIVE-LAYER bilayer structure; charge transport characteristics; oxide semiconductors; positive bias stability; semiconductor thickness control; thin-film transistors Carrier concentration; Carrier mobility; Carrier transport; Dry cleaning; Electrospinning; Gluing; Hard facing; Heterojunction bipolar transistors; Indium phosphide; Layered semiconductors; Leakage currents; Oxide films; Thick film circuits; Thin film circuits; Bi-layer; Bi-layer structure; Bias stability; C. thin film transistor (TFT); Charge transport characteristic; Positive bias; Positive bias stability; Semiconductor thickness; Semiconductor thickness control; Transport characteristics; Heterojunctions English 2025 2025-02 10.1002/aelm.202400328 바로가기 바로가기 바로가기 바로가기
Article High color purity plasmonic color filters integrating Fabry Perot interferometer with distributed Bragg reflector We present a novel nano structure which combines a Fabry-perot interferometer (FPI) with a plasmonic color filter (PCF) to enhances color purity without increasing fabrication complexity. In the suggested structure, the additional optical resonance operates independently of plasmonic resonance. An FPI was selected for its strong resonance with minimal layers, effectively addressing the wavelength-dependent cavity thickness problem. By optimizing higher-order resonance modes within the FPI, we achieved one cavity of structure with selective transmission peaks at red, green , blue wavelengths, significantly increasing the color gamut by 118.35 % improvement. While the metal-based FPI with PCF (MPCF) exhibited limited peak transmittance due to ohmic loss, the optimized dielectric based FPI with PCF (DPCF) achieved higher transmittance up to 46.81 % , superior color selectivity with a narrow FWHM of 16 nm in blue filter. This led to a 120.29 % enhancement in color purity. Our findings highlight the potential of DPCFs in high-resolution imaging devices, offering a robust alternative to conventional color filters. Future work will focus on optimizing fabrication and exploring materials for further enhancement.

Article Synthesis of fluorescent dyes for polyolefin fibers and their fluorescence emission properties Two novel greenish-yellow fluorescent dyes sharing the same chromophore were synthesized. Dibutyl groups were introduced into the chromophore to enhance their affinity for extremely hydrophobic polyolefin materials, such as polypropylene and ultra-high molecular weight polyethylene (UHMWPE). Despite the similarity in their chromophores, the dye-containing sulfur atoms exhibited significantly superior fluorescence emission properties compared to the dye-containing oxygen atoms, likely due to the heavy atom effect. Comparative experiments involving different dyes, fabrics, and dyeing conditions demonstrated that polyolefin fabrics, previously undyeable with commercial dyes, were successfully dyed with the synthesized fluorescent dyes, maintaining excellent fluorescence properties after application. Additionally, the dyed fabrics exhibited excellent washability and color fastness, except for light fastness.

Article Amelioration of Alcoholic Hepatic Steatosis in a Rat Model via Consumption of Poly-γ-Glutamic Acid-Enriched Fermented Protaetia brevitarsis Larvae Using Bacillus subtilis Alcoholic hepatic steatosis (AHS) is a common early-stage symptom of liver disease caused by alcohol consumption. Accordingly, several aspects of AHS have been studied as potential preventive and therapeutic targets. In this study, a novel strategy was employed to inhibit fatty liver accumulation and counteract AHS through the consumption of microorganism-fermented Protaetia brevitarsis larvae (FPBs). By using an AHS rat model, we assessed the efficacy of FPB by examining the lipid profile of liver/serum and liver function tests to evaluate lipid metabolism modulation. After FPB administration, the lipid profile-including high-density lipoprotein, total cholesterol, and total triglycerides-and histopathological characteristics exhibited improvement in the animal model. Interestingly, AHS amelioration via FPBs administration was potentially associated with poly-gamma-glutamic acid (P gamma G), which is produced by Bacillus species during fermentation. These findings support the formulation of novel natural remedies for AHS through non-clinical animal studies, suggesting that P gamma G-enriched FPBs are a potentially valuable ingredient for functional foods, providing an ameliorative effect on AHS.
