It aims to develop a digitally integrated mental healthcare platform that integrates robots, artificial intelligence, and local community services. A total of 3,100 participants, including 1,000 from the previous Chungnam Province cohort and 700 each from Chungnam, Gangwon, and Daegu, will be recruited between December 2024 and the end of 2027. Sociodemographic factors and physical health data are collected at enrollment using questionnaires. Every four months, formal tools are used to conduct psychiatric diagnoses and determine participants’ mental health condition, such as depressive symptoms, anxiety symptoms, suicidality, stress, insomnia, loneliness, quality of life, and disability. We assessed smartphone overdependence at regular intervals. Passive data on phone usage, life patterns, and health monitoring from a smart band are collected in real time. Weekly ecological momentary assessments monitor daily life and mood and detect risk situations early. A subset of 500 participants engages in a Living Lab, collecting multi-modal data through robots and sleep radar sensors while evaluating the usability of and satisfaction with these devices. This study will show how tailored digital applications and web-based platforms can facilitate personalized self-help interventions, enhance expert–user interaction, and promote active user engagement. This approach can potentially reduce stigma and improve public awareness of mental healthcare by shifting from a treatment-centered model to a community-based prevention framework.</div></div>","PeriodicalId":390,"journal":{"name":"Methods","volume":"247 ","pages":"Pages 41-49"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145846209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Variability in biomarker results can be contributed to non-standardized collection methodology. To address this, a novel microsampler was developed, designed to enable precise site-specific sampling, consistent volume collection, and high analyte recovery. This study aims to evaluate the performance of this new microsampler device compared to commonly utilized flocked swab, and other absorbent materials. To do so, fixed volumes of a synthetic nasal fluid mimic were deposited onto the anterior region of the inferior turbinate of a 3D-printed sinus model to assess volumetric and collection site accuracy of the nasal microsampler, in comparison to a flocked swab. Additionally, protein biomarker recovery properties of the device’s absorption membrane, Leukosorb^TM, versus experimental proprietary absorbent materials, were assessed using ELISA. The microsampler, contrasting the flocked swab, demonstrated statistically significant lower coefficient of variation for collected nasal fluid volume and greater sampling site precision. The spike and recovery study indicated that the proprietary materials had statistically significant higher biomarker recovery rates than Leukosorb^TM. Overall, the novel nasal microsampler offers significantly improved volumetric control and site-specific collection against flocked swab. All experimental proprietary absorbent materials displayed significantly higher protein recovery rates, comparing to widely accepted and utilized Leukosorb^TM. Consistent use of the novel nasal microsampler device has the potential to standardize protein recovery processes and minimize variability across studies, leading to enhanced reliability and comparability of future findings.</div></div>","PeriodicalId":390,"journal":{"name":"Methods","volume":"247 ","pages":"Pages 25-33"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145800355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Together with TPP1, POT1 plays a crucial role in regulating telomere length and protecting telomeres from DNA damage repair proteins. The activation of DNA damage repair proteins at telomeres can be detrimental to cells, so their activity must be suppressed. POT1 interacts with other telomeric proteins (TRF2, TRF1, TIN2 and RAP1) via its association with TPP1. These proteins function together to protect and maintain the telomeres. Despite extensive knowledge of POT1′s role within the shelterin complex, the full spectrum of its interactors at the single-stranded telomeric overhang remains poorly defined. To study these interactions, we generated an endogenous Flag-tag knock-in of POT1 using the CRISPR-Cas9 gene editing system. To address the risk of unintended gene disruption associated with this technique, we conducted an in-depth characterization of the endogenously Flag-tagged POT1 clone to ensure that its telomere and TPP1 binding functions remained intact. Further, we performed proteomic profiling of the Flag-tagged POT1 within the chromatin fraction using ChIP-MS to explore its proteome. Our analysis uncovered a novel set of POT1-associated proteins at the extremes of telomeres. Given that POT1 exclusively binds to the single-stranded 3′ overhang of telomeres, the proteomic data obtained indicates POT1 interactions occurring at the extreme ends of telomeres. In conclusion, our study reveals previously uncharacterized POT1 associated proteins using ChIP mass spectrometric approach, paving the way for further investigations into telomere biology and potential therapies targeting telomere regulation.</div></div>","PeriodicalId":390,"journal":{"name":"Methods","volume":"247 ","pages":"Pages 161-174"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146040153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first critical step in these experiments is preparing the surface using polyethylene glycol (PEG) coated slides, which facilitate biomolecule immobilization while minimizing non-specific interactions. The surface treatment typically uses PEG-SVA (Succinimidyl Valerate) coated slides, and the protocol for the treatment is lengthy and time-consuming.

Using NF-κB as a model TF, we demonstrate the feasibility of DULF in visualizing the spatiotemporal details of a sequence-specific TF-DNA interaction. The high temporal resolution of our data reveals that TF-DNA binding proceeds through a rapid recognition step and a subsequent slower stabilization phase. DULF also revealed that the p50 homodimer binds specifically to DNA outside the canonical binding site, emphasizing the role of flanking sequences in these interactions. All-atom molecular dynamics simulations confirmed that DNA sequence context, including flanking base pairs, modulates NF-κB binding stability and induces local structural changes such as bending, groove widening, and base unstacking. DULF offers a unique opportunity to study DNA-protein interactions at unprecedented resolution, providing insights into the mechanism of sequence-specific binding and stabilization of chromatin interactors.</div></div>","PeriodicalId":390,"journal":{"name":"Methods","volume":"247 ","pages":"Pages 50-62"},"PeriodicalIF":4.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145922632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, metal–organic framework (MOF) NPs have attracted significant attention owing to their unique characteristics absent in their larger-scale counterparts. These properties make MOFs suitable for various functional platforms. MOF-based nanomaterials exhibit high antibacterial potential, owing to their biocompatibility, biodegradability, and safety for living organisms. They have also become a prominent component in the development of anticancer agents and in the manufacture of commercial medical products. Consequently, MOFs are becoming increasingly important in dentistry. They show promising therapeutic potential for inhibiting oral infectious diseases, such as those caused by bacterial plaque, and have a broad range of other biomedical applications, including the diagnosis and treatment of dental diseases. However, significant challenges hinder their transition from laboratory testing to widespread clinical use in hospitals. Key issues include long-term toxicity and biocompatibility concerns, unpredictable pharmacokinetics that can lead to unintended accumulation in organs like the liver and spleen, and the potential for adverse immune reactions. Other major obstacles are particle aggregation in biological fluids, the complex formation of a “protein corona” that can alter the NPs’ intended function, and the high cost of large-scale production under consistent Good Manufacturing Practices (GMP). This article discusses MOFs and their potential applications in identifying cancer biomarkers and treating tooth infections and oral cancers.
