“…However, Foods 2023, 12, 1896 2 of 15 visual colorimetry is less accurate than photoelectric colorimetry because it is difficult to distinguish subtle color differences by observing the target color level with the naked eye [13]. Nowadays, the combination of colorimetric methods, image acquisition tools (such as cell phones, cameras, and scanners), and processing software (such as Adobe Photoshop [14], Image J [15], MATLAB [16], Pantone Studio [17], etc.) provides a new method for simple and accurate colorimetric detection, which can eliminate the subjective error of the observer and further improve the accuracy of visual observation in the field [18].…”

Traditional methods for evaluating the edibility of lipids involve the use of organic reagents and complex operations, which limit their routine use. In this study, nanocellulose was prepared from bamboo, and a colorimetric reading strategy based on nanocellulose composite hydrogels was explored to monitor the freshness of edible oils. The hydrogels acted as carriers for peroxide dyes that changed color according to the freshness of the oil, and color information was digitized using UV-vis and RGB analysis. The sensitivity and accuracy of the hydrogel were verified using H2O2, which showed a linear relationship between absorbance and H2O2 content in the range of 0–0.5 and 0.5–11 mmol/kg with R2 of 0.9769 and 0.9899, respectively, while the chromatic parameter showed an exponential relationship with R2 of 0.9626. Surprisingly, the freshness of all seven edible oil samples was correctly identified by the hydrogel, with linear correlation coefficients greater than 0.95 in the UV-vis method and exponential correlation coefficients greater than 0.92 in the RGB method. Additionally, a peroxide value color card was established, with an accuracy rate of 91.67%. This functional hydrogel is expected to be used as a household-type oil freshness indicator to meet the needs of general consumers.

“…В последнее время для подбора цвета кожи используются цифровые технологии Pantone SkinTone Guide (Pantone LLC, X-Rite). Это удобные портативные инструменты, использующие цифровую библиотеку из почти 20 000 оттенков кожи, которые реалистично имитируют оттенки кожи человека, с пошаговыми изменениями света и тени [ 28,29 ] .…”

Реконструкция черепно-лицевых дефектов остается сложной задачей, несмотря на последние достижения в хирургических методах лечения. Во многих случаях челюстно-лицевые протезы обеспечивают эффективную реабилитацию сложных дефектов лица как альтернатива хирургической реконструкции. Наиболее часто в челюстно-лицевом протезировании используют силиконы, благодаря специфическим свойствам которых правильно изготовленный эпитез может очень точно повторять структуру и внешний вид утраченного органа. В сочетании с функциональными результатами эстетика играет важную роль в самооценке, идентичности и социальной реинтеграции пациентов. Обеспечение приемлемого соответствия цвета кожи пациента и эпитеза — важный компонент эстетического успеха. Цель исследования — клиническая оценка эффективности применения системы Pantone SkinTone Guide для моделирования цвета кожи пациентов при протетической реабилитации дефектов средней зоны лица. Проведена реабилитация 50 человек с дефектами различной локализации и генеза эпитезами из жестких силиконовых эластомеров с применением CAD/CAM-технологий. Цвет кожи определяли с помощью портативного колориметра Capsure RM200 (X-Rite, США). Для клинического анализа цветоадаптации конструкций проводили опрос пациентов по специально разработанной анкете. Все пациенты положительно оценили качество изготовленных эпитезов. Отметили качество цветоадаптации как отличное и хорошее 44 (88%) пациента. По оценке пациентов, внимание окружающих людей эпитезы привлекали редко (36%) или никогда (48%). Клинический пример проиллюстрировал удовлетворительное состояние эпитеза и фиксирующих элементов, хорошее соответствие цвета эпитеза здоровым тканям через 5 лет наблюдения. Получение высококачественного эпитеза с высокими свойствами по биологической совместимости и биологической стабильности по отношению к живым тканям пациента приводит к значительному повышению качества жизни и социальной реабилитации пациентов с челюстно-лицевыми дефектами. Reconstruction of craniofacial defects remains challenging despite recent advances in surgical techniques. In many cases, maxillofacial prostheses provide effective rehabilitation of complex facial defects as an alternative to surgical reconstruction. The most commonly used materials in maxillofacial prosthetics are silicones, whose specific properties allow a properly fabricated prosthesis to closely mimic the structure and appearance of the lost organ. In combination with functional results, aesthetics play an important role in the patient's self-esteem, identity and social reintegration. Ensuring an acceptable match between the patient's skin colour and the epithesis is an important component of aesthetic success. The purpose of this study was to clinically evaluate the efficacy of the Pantone SkinTone Guide System for modelling patient skin colour in the prosthetic rehabilitation of midface defects. . Fifty subjects with defects of various localisations and aetiologies were rehabilitated with rigid silicone elastomer epithetics using CAD/CAM technology. Skin colour was measured using a Capsure RM200 portable colorimeter (X-Rite, USA). For the clinical analysis of the colour adaptation of the designs, patients were interviewed using a specially designed questionnaire. . All patients rated the quality of the manufactured epithesis positively. The quality of colour matching was rated excellent and good by 44 (88%) patients. Patients felt that the epitheses rarely (36%) or never (48%) attracted the attention of those around them. A clinical example illustrated the satisfactory condition of the epithesis and fixation elements, good colour matching of the epithesis with healthy tissue after 5 years of follow-up. . Obtaining a high-quality prosthesis with high biocompatibility and biological stability properties in relation to the patient's living tissues leads to a significant improvement in the quality of life and social rehabilitation of patients with maxillofacial defects.
