The aim of this study was to evaluate the color stability of bulk-fill and conventional resin composites with respect to different storage media and thickness of composites.Filtek™ Z250 and Filtek™ Z350XT were evaluated as conventional resin composites. Filtek™ Bulk-fill Posterior Restorative and Tetric® N-Ceram Bulk Fill were evaluated as bulk-fill resin composites.CIE L*a*b* values of baseline were measured after 24 hours of storage in distilled water, and each resin composite group was divided into three subgroups and stored in distilled water, red wine, and coffee media respectively. Again after 1, 7 and 28 days of immersion, color changes (ΔE*) were calculated using the CIE L*a*b* values.The greatest ΔE* was observed in red wine for all resin composites, and the mean color changes were ranked in the increasing order of distilled water, coffee, red wine. Filtek™ Z350XT exhibited the greatest color change in all media, followed by Filtek™ Bulk-fill Posterior Restorative. Filtek™ Z250 and Tetric® N-Ceram Bulk Fill followed with similar mean color change values. According to the 2 different thicknesses of 2 mm and 4 mm of bulk-fill resin composites, there was no thickness-related difference on color changes.

Six compounds were isolated from aqueous extract of wine-processed Corni Fructus through silica gel, ODS column chromatography, Sephadex LH-20 gel column chromatography, reverse phase preparative HPLC and other chromatographic separation technologies. Their structures were identified with multiple spectroscopical methods including HR-ESI-MS, UV, IR, NMR and ECD and so on. Their structures were established as pinoresinoside B(1), cornusgallicacid A(2),(+)-isolariciresinol-9'-O-β-glucopyranoside(3),(-)-isolariciresinol 3α-O-β-D-glucopyranoside(4),(7R,8S)-dihydrodehydrodiconiferyl alcohol 9-O-β-D-glucopyranoside(5), and(-)-seco isolariciresinol-9'-O-β-D-glucopyranoside(6). Among them, compounds 1 and 2 were two new compounds. The biological activity evaluation results showed that compounds 2 and 6 had strong DPPH free radical scavenging ability, with EC_(50) values of(4.18±1.96) and(21.45±1.19) μmol·L~(-1), respectively. Compounds 1 and 2 had protective effects on H_2O_2-induced oxidative damage in NRK-52E cells in a dose-dependent manner, and the cell survival rate of compound 2 at 100 μmol·L~(-1) was 96.09%±1.77%.

Separation of vascular lesions into one of the two groups, namely, hemangioma and vascular malformations can be of considerable significance relative to the treatment of patients. They pose serious bleeding risks. A case report is presented here where a patient with a vascular malformation is treated with fixed orthodontic appliances. A coordinated, interdisciplinary approach can result in enhanced patient satisfaction and successful treatment outcomes.

OBJECTIVES: This study investigated the effect of red and white wine on color changes of nanofilled and nanohybrid resin composite. MATERIALS AND METHODS: Sixty specimens of each resin composite were prepared. Baseline data color values were recorded using a spectrophotometer. Three groups of discs (n = 20) were then alternately immersed in red, white wine, and deionized water (as a control) for twenty five minutes and artificial saliva for five minutes for four cycles. Specimens were then stored in artificial saliva for twenty two hours. This process was repeated for five days following immersion in artificial saliva for two days. Subsequently, the process was repeated again. Data were analyzed by two-way repeated ANOVA, one-way ANOVA, and Tukey's HSD. RESULTS: Red wine caused significantly higher color change (ΔE* > 3.3) than did white wine and deionized water (p < 0.05). Nanohybrid resin composites had significantly more color changes than nanofilled resin composite (p < 0.05). CONCLUSIONS: The effect of red and white wine on the color changes of resin composite restorative materials depended upon the physical and chemical composition of the restorative materials and the types of wine.

Ethyl carbamate (EC), a carcinogenic and teratogenic chemical that is widely distributed in various alcoholic beverages, has attracted much attention. Microbial enzymatic degradation of EC in rice wine is always efficient and attractive. In this review, we summarize the research progress and problems of microbial enzymatic elimination of EC in rice wine from three aspects: the mechanisms of EC formation in rice wine, the research progress of acid urease, and the research progress of urethanase. Then, we propose the corresponding strategies to solve the problems: screening new urethanase with satisfied enzyme properties, food-grade expression and directed evolution of the bifunctional Fe³⁺-dependent acid urease and acid urease used in combination with urethanase to eliminate both urea and EC in rice wine.

Background: Tapuy is an indigenous fermented rice wine produced in the Northern areas of the Philippines. Fermented foods and drinks have gained interest due to their associated health benefits, attributable to probiotic bacteria in the food items. However, pathogenic bacteria may also be present in fermented food and pose health risks, signifying a need for standardization. Currently, there is limited knowledge on the bacterial content of tapuy. Objectives: This study aimed to characterize the bacterial diversity and community structure of culturable bacteria in traditionally fermented tapuy samples, to perform standardization of tapuy fermentation, and to compare the bacterial diversity and community structure of culturable bacteria in laboratory fermented tapuy with that of the traditional samples. Methods: Tapuy samples were obtained from four municipalities in Benguet, Philippines. Laboratory fermentation of tapuy was performed simultaneously with the fermentation in the sampling site using a standardized protocol. Samples were plated on de Man, Rogosa, and Sharpe (MRS) agar and NA, and the colonies were harvested for DNA extraction. DNA samples were sent for 16S rDNA metagenomic sequencing. Results. Metagenomic analysis revealed the presence of many bacterial species that were previously unreported in tapuy. Traditional tapuy samples were composed primarily of members of the genera Bacillus and Lactobacillus in varying proportions. Potential probiotic bacteria were abundant in Kapangan (97.42%) and Sablan (99.89%) field samples. B. wiedmannii was present in all samples and was identified as a harmful species. Laboratory fermentation increased the abundance of potential probiotic bacteria in Itogon and La Trinidad samples (differences of 75.36% and 78.36%, respectively). It decreased the quantity of B. wiedmannii in La Trinidad (a difference of 97.1%). Laboratory fermented samples generally exhibited higher bacterial diversity and species richness compared to field samples. Conclusions Traditionally fermented tapuy samples contained a significant proportion of potential probiotic bacteria belonging to the genera Bacillus and Lactobacillus. Laboratory fermented samples were found to have higher bacterial diversity and richness compared to field samples. The significant presence of potential probiotic bacteria suggests that tapuy is a good candidate for development into functional food and a good source of likely probiotic species that could be explored for health applications. The presence of harmful bacteria suggests the need for possible standardization of fermentation practices.
