The device, called CELL-LED-550/3, consists of two 3D-printed parts, one generating a 550 nm green light from a single LED (the light source part) and the other distributing this light to a 96-well cell culture plate (the light distributor part). The light source part is controlled by a driver with three different modes, enabling the light distributor part to deliver three different irradiance levels to the bottom exterior surface of the wells: 0.02 mW/cm<sup>2</sup>, 0.23 mW/cm<sup>2</sup>, or 0.62 mW/cm<sup>2</sup>. The light distributor part was designed to illuminate the wells individually and simultaneously. To demonstrate the relevance of the CELL-LED-550/3 device, its ability to induce cell death by RB-mediated PDT on HepG2 hepatocellular carcinoma cells was evaluated. First, HepG2 cells were treated for 2 h with increasing concentrations of Rose Bengal, a photosensitizer with an absorption peak (the highest one) at around 550 nm. The treated cells were then illuminated using the CELL-LED-550/3 device set to its maximum irradiance level at light doses of 0.3 J/cm<sup>2</sup>, 0.6 J/cm<sup>2</sup>, and 1.2 J/cm<sup>2</sup> (respectively, with illumination times of 8 min and 4 s, 16 min and 8 s, and 32 min and 16 s). Finally, viability was measured using Cell-Titer Glo at 24 h post-PDT. The experimental results show that RB-mediated PDT using the CELL-LED-550/3 device is capable of inducing a decrease in the viability of HepG2 cells, in a manner dependent both on the concentration of Rose Bengal and on the administered dose of light.

A zone 2 arch can often be performed with a branched or straight graft and with head vessel anastomoses in the aortic arch. In four studies published to date comparing outcomes following proximal (zone 0/1) or more distal (zone 2) anastomoses, the majority of outcomes, including mortality, stroke, and aortic remodeling, were not significantly different.

This study investigates four unique cases of forearm synovitis with rice body formation, hypothesizing that diverse underlying causes-rheumatoid arthritis, trauma, and idiopathic inflammation-contribute to this condition, and that surgical intervention ensures symptom resolution and prevents recurrence. The patients (three males, one female; aged 42-76 years) presented with heterogeneous clinical manifestations, including localized swelling, nerve compression symptoms, and restricted joint mobility. Diagnostic MRI revealed characteristic features: T1-weighted isointense masses with T2-weighted high-signal foci containing punctate low signals, aiding differentiation from other synovial pathologies. All patients underwent radical synovectomy with median nerve decompression, followed by histopathological analysis. Results demonstrated chronic granulomatous synovitis without evidence of infection (negative cultures and stains for tuberculosis, fungi, and bacteria). Postoperatively, all patients achieved complete symptom relief, with no recurrence or functional deficits observed during follow-up (9-22 months). Literature review highlighted the rarity of forearm rice bodies and underscored MRI's diagnostic superiority over radiography. The cases underscore that rice body formation, while historically linked to rheumatoid arthritis or tuberculosis, can arise from nonspecific synovial inflammation or trauma. Surgical excision combined with nerve release emerged as the definitive treatment, addressing both mechanical compression and inflammatory burden. This study emphasizes the importance of considering diverse etiologies in forearm synovitis, advocating for early MRI evaluation and tailored surgical management to optimize outcomes. The findings contribute to understanding the multifactorial pathogenesis of rice bodies and reinforce the efficacy of synovectomy in preventing recurrence and restoring function.</p>","PeriodicalId":48787,"journal":{"name":"Jove-Journal of Visualized Experiments","volume":" 223","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145193004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its secretion is modulated by various intrinsic and extrinsic factors, including microbial infections and inflammation. While traditional methods for mucus analysis rely on relative quantification, such as measuring mucus thickness in histological sections, these approaches provide limited insight into the actual volume and spatial distribution of secreted mucus within the intestinal lumen. Here, we present a detailed methodology for the absolute, three-dimensional quantification of mucus using whole-mount intestinal tissues and multi-photon microscopy. This protocol includes the preparation of ligated intestinal loops, treatment with carbamoylcholine chloride as a stimulus for goblet cell activation, tissue fixation, and staining for imaging. Using multi-photon microscopy, we acquire Z-stacked images of the luminal surface. These are processed in Imaris software to quantify the volume and spatial distribution of secreted mucus. We demonstrate that carbamoylcholine chloride robustly induces mucus secretion in both ileal and colonic tissues within 30 minutes. The secreted mucus appears in a sporadic and discontinuous manner throughout the lumen, underscoring the importance of volumetric analysis over traditional two-dimensional approaches. This protocol enables researchers to obtain absolute quantitative data and visualize mucus distribution in situ, offering a powerful tool for studying intestinal mucus dynamics under physiological and pathological conditions.</p>","PeriodicalId":48787,"journal":{"name":"Jove-Journal of Visualized Experiments","volume":" 223","pages":""},"PeriodicalIF":1.2,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145193203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many details of this process remain enigmatic due to the complexity of the involved molecular machinery and transient protein-protein interactions. Here, we present a method for time-resolved labeling of proteins with biotin located close to a target protein of interest. The method can easily be adapted to different targets since the biotinylation is achieved by injection of a DNA encoding a target protein fused to an engineered biotin ligase. The fusion construct is expressed from the promoter of the endogenous gene, enabling a stage-specific expression profile similar to that of the native protein. Notably, the covalently attached biotin moiety allows for the selective enrichment of the labeled proteins using streptavidin-coated beads. Furthermore, with immunofluorescence staining, we show that efficient labeling requires supplementation of the culture with biotin. The plug-and-play engineered expression vector, combined with the efficient injection procedure demonstrated here, allows for the rapid generation of Paramecium lines expressing a modified protein. The biotinylation procedure demonstrated here can be followed up with mass spectrometry for the identification of the enriched proteins that contain the interacting partners of the target protein.

This paper introduces a modified numerical model for frost formation, developed based on the fundamental mechanisms underlying frost formation. The model utilizes an Eulerian multiphase flow approach coupled with the Lee phase change model. In addition, the approach for determining the maximum frost volume fraction is updated, enabling the model to consider density variations during the frosting process. The model is rigorously validated by comparing it with experimental data on thickness, density, and distribution from various studies. The results indicate that the mean absolute relative deviation (MARD) for frost thickness is 8.97%, while the MARD for density is 16.06%.
