Due to its course in the tympanic cavity and its relation to the ossicular chain, there is a high risk of iatrogenic damage to the CTN during otologic surgeries. This study aimed to assess the impact of different handling methods of the CTN during endoscopic ear surgery on patients' taste perception. A cohort study conducted from 2022 to 2023 in a tertiary hospital involved participants undergoing various types of endoscopic ear surgeries. Based on intraoperative handling of the CTN, participants were divided into three groups: intact, traction (subdivided into mild, moderate and severe traction subgroups) and transection (subdivided into transection without tension, with tension and tearing subgroups). Taste tests were administered from 1 day before surgery to 6 months postoperatively. Endoscopic ear surgery for treating ear pathologies. Taste test scores, other relevant symptoms. Significant differences were observed in the incidence and recovery time of taste dysfunction across groups. The rate of taste abnormalities and recovery time increased with the degree of traction; the severe traction and transection subgroups showed the highest rates of abnormalities and cases of incomplete recovery. In terms of disease type, patients with chronic suppurative otitis media and cholesteatoma showed significant differences in preoperative taste status, abnormality rates and recovery times compared to patients with non-inflammatory ear diseases. General sensory abnormalities of the tongue were mainly found in moderate-to-severe traction subgroups and all transection groups, often accompanying taste reduction or loss. Some patients in the transection group experienced only numbness or both increased taste sensation and numbness. The study underscores the importance of delicate handling of the CTN in endoscopic ear surgery, especially in patients with inflammatory middle ear diseases. It suggests minimising severe traction injuries and considering early and accurate transection to reduce traction injuries when preservation is challenging; any manipulation of the CTN should be avoided in patients with non-inflammatory conditions. This research provides valuable theoretical support for clinical practice.</p>\u0000 </div>","PeriodicalId":170,"journal":{"name":"Flavour and Fragrance Journal","volume":"40 1","pages":"132-141"},"PeriodicalIF":2.1,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142861978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both B cells and follicular helper T cells (Tfhs) have important roles in allergic diseases. However, how Tfhs and B cells interact to modulate allergic rhinitis pathogenesis remains unclear. In this study, two models of allergic rhinitis were examined, including the co-culture of follicular helper T cells (Tfhs) isolated from mouse spleen with B cells. To further define the mechanism, exosomes from Tfh cells were isolated and added to B cells. Bulk RNA sequencing (RNA-seq) analysis was used to compare exosomes derived from Tfhs cells in a mouse model of allergic rhinitis and exosomes derived from Tfhs cells in wild-type mice. Among them, miR-149-5p was observed to be lowly expressed in the allergic rhinitis group, which was confirmed using qPCR. miR-149-5p mimics or inhibitors were utilised to overexpress or knock down miR-149-5p in Tfhs, which were then co-cultured with B cells, demonstrating that miR-149-5p is negatively correlated with B cell proliferation and maturation. The function of WNT3A, a target gene of miR-149-5p, and the downstream effector AXIN2 on the proliferation and maturation of B cells were predicted and verified.

However, the market is plagued by adulterated lavender oil, often mixed with cheaper alternatives such as eucalyptus and rosemary. Current detection methods, primarily gas chromatography, are expensive, time-consuming and often fail to detect low levels of adulteration. To address these limitations, this study examines the use of mid-infrared spectroscopy for the detection and prediction of adulteration levels. A set of 105 samples, comprising pure lavender oil and adulterated lavender oil, was prepared in the laboratory. Principal component analysis (PCA), hierarchical clustering ascending (HCA) and K-means clustering were applied to the FT-MIR results for qualitative analysis to effectively discriminate between authentic and adulterated essential oils. For quantitative analysis, partial least squares regression (PLSR) was used to develop accurate calibration models for predicting the percentage of adulteration. The results from PCA, HCA and K-means demonstrated the efficacy of these techniques in detecting adulteration, even at low levels (2%). Calibration models were developed using the PLSR method with different spectral preprocessing techniques to predict the percentage of adulteration, with results indicating that models generated on the raw data and those using MSC (multiplicative signal correction) pre-processing are optimal. In addition, the use of interval-partial least squares (IPLS) variable selection techniques (Forward, Backward) improved the predictive accuracy of the models developed by reducing the number of wavelengths used.</p>\u0000 </div>","PeriodicalId":170,"journal":{"name":"Flavour and Fragrance Journal","volume":"40 1","pages":"103-113"},"PeriodicalIF":2.1,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142860800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The QbD approach for delivery system design involves classifying critical quality attributes of the product and process, defining the critical process parameters and developing a design space to ensure product quality within the specified range. In addition, risk assessment and mitigation strategies are also a component of the QbD techniques, which ensure the robustness of the delivery system.

These delivery systems provide controlled release, protection, and enhanced stability of the active ingredients. However, challenges such as scale-up, reproducibility, and cost-effectiveness need to be addressed to ensure their commercial viability. In conclusion, the QbD outlook provides a comprehensive framework for the design of carrier system for fragrance and flavour applications.

An increase in woody intensity was notably perceived in samples with a low-mint profile and containing wood compounds associated with medium and long-term maturation.
