Summary: This study presents the first comprehensive identification of proteome content from a white wine (cv. Silvaner). By using mass spectrometry-based proteomics, the wine protein composition was identified through in-solution and in-gel digestion methods after size exclusion chromatographic fractionation. A total of 154 characterized or uncharacterized proteins mainly from Vitis vinifera L. and Saccharomyces cerevisiae were identified, providing valuable information for wine authentication and understanding of organoleptic properties and stability.

Summary: This study investigates the effects of gibberellin and cytokinin on the size and composition of grapes, as well as their subsequent impact on wine attributes. The results show that these plant growth regulators can increase berry diameter and weight, but also reduce sugar accumulation and color development. Furthermore, they affect the levels of flavan-3-ols, flavonols, anthocyanins, proanthocyanidins, and fatty acid derived volatile compounds in the berries, ultimately influencing the phenolic composition of the resulting wine.

Summary: The enology industry in North Dakota is young, with less than twenty years of existence. In order to investigate the fermentation outcomes related to skin contact for red grapevine musts, a postfreeze fermentation experiment was conducted with fruit from the 'Frontenac' grapevine. Steam juice extraction, rose, 1 DAI skin contact, and 9 DAI skin contact were the four fermentation treatments applied to the musts. Differences were found between the treatments, but the wines remained visually similar, indicating that color extraction within the freeze-thaw processes of musts may affect the production of light-colored wines.

Photophysical properties and aggregate formation in phosphate buffer were studied. Singlet oxygen production was assessed using the 1,3-diphenylisobenzofuran assay. Antifungal activity was tested using Saccharomyces cerevisiae PYCC 4072, and some of the dyes showed improved activity after irradiation. Colocalization in yeast cells and the potential as a fluorescent probe for HSA detection were investigated.

Summary: The degradation of caffeic acid in model agro-industrial wastewater was studied using a UV-A-Fenton system. Batch experiments showed that pH 3.0 achieved higher generation of HO center dot and thus higher caffeic acid degradation (>99.5%). The effects of H2O2 and Fe2+ concentrations were evaluated, and a pseudo first-order kinetic model was found to fit the results. Continuous mode experiments were performed at different flow rates, showing that increasing the flow rate resulted in significantly higher removal rates of caffeic acid and dissolved organic carbon (DOC). It is concluded that continuous modes are advantageous for treating real agro-industrial wastewaters.

Summary: The introduction of amines into squaraine dyes improved their aqueous solubility, absorption at higher wavelengths, and interaction with biological targets. The synthesis of N-ethyl chain benz[e]indole-based amino-squaraine dyes with increasing amine complexity was conducted to investigate the impact of small modifications on their photobiological activity. Amino and hydroxyethylamino-bearing dyes exhibited promising results in silico and cytotoxicity assays, with strong binding to human serum albumin protein and high rates of photocytotoxicity and tumor selectivity. Further studies showed that these dyes are linked to mitochondria, have low genotoxicity, and induce cell cycle arrest in the G2/M phase.

Summary: A new photoswitchable photoinitiator was developed by combining photochromic naphthopyran with a Norrish-type II benzophenone photoinitiator, which can be activated by absorbing two different wavelengths of light successively. This dual-colour photoinitiator was employed in the preparation of various thin solid polymeric materials using UV and visible light LED to initiate the polymerization of an acrylate monomer. The use of this system enables precise control of polymerization by selectively polymerizing only the areas that receive double irradiation.

Summary: Lung cancer, with one of the lowest survival rates, is the main malignant cancer reported worldwide. Deletions in the Epidermal Growth Factor Receptor (EGFR) gene are often associated with non-small cell lung cancer (NSCLC), a common subtype of lung cancer. The development of a DNA-based biosensor, namely a quartz crystal microbalance (QCM), applied to the detection of NSCLC, was reported in this study. The biosensor was able to detect specific DNA sequences in both synthetic and real samples, and aspects such as reutilization and regeneration of the QCM electrode were also studied.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
