Marr RA, Moore J, Formby S, Martiniuk JT, Hamilton J, Ralli S, Konwar K, Rajasundaram N, Hahn A, Measday V. Whole genome sequencing of Canadian Saccharomyces cerevisiae strains isolated from spontaneous wine fermentations reveals a new Pacific West Coast Wine clade. G3 (BETHESDA, MD.) 2023; 13:jkad130. [PMID: 37307358 PMCID: PMC10411583 DOI: 10.1093/g3journal/jkad130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 05/19/2023] [Accepted: 05/22/2023] [Indexed: 06/14/2023]
Abstract
Vineyards in wine regions around the world are reservoirs of yeast with oenological potential. Saccharomyces cerevisiae ferments grape sugars to ethanol and generates flavor and aroma compounds in wine. Wineries place a high-value on identifying yeast native to their region to develop a region-specific wine program. Commercial wine strains are genetically very similar due to a population bottleneck and in-breeding compared to the diversity of S. cerevisiae from the wild and other industrial processes. We have isolated and microsatellite-typed hundreds of S. cerevisiae strains from spontaneous fermentations of grapes from the Okanagan Valley wine region in British Columbia, Canada. We chose 75 S. cerevisiae strains, based on our microsatellite clustering data, for whole genome sequencing using Illumina paired-end reads. Phylogenetic analysis shows that British Columbian S. cerevisiae strains cluster into 4 clades: Wine/European, Transpacific Oak, Beer 1/Mixed Origin, and a new clade that we have designated as Pacific West Coast Wine. The Pacific West Coast Wine clade has high nucleotide diversity and shares genomic characteristics with wild North American oak strains but also has gene flow from Wine/European and Ecuadorian clades. We analyzed gene copy number variations to find evidence of domestication and found that strains in the Wine/European and Pacific West Coast Wine clades have gene copy number variation reflective of adaptations to the wine-making environment. The "wine circle/Region B", a cluster of 5 genes acquired by horizontal gene transfer into the genome of commercial wine strains is also present in the majority of the British Columbian strains in the Wine/European clade but in a minority of the Pacific West Coast Wine clade strains. Previous studies have shown that S. cerevisiae strains isolated from Mediterranean Oak trees may be the living ancestors of European wine yeast strains. This study is the first to isolate S. cerevisiae strains with genetic similarity to nonvineyard North American Oak strains from spontaneous wine fermentations.

Study of the Stability of Wine Samples for 1H-NMR Metabolomic Profile Analysis through Chemometrics Methods. Molecules 2023; 28:5962.

Abstract
Wine is a temperature, light, and oxygen-sensitive product, so its physicochemical characteristics can be modified by variations in temperature and time when samples are either sampled, transported, and/or analyzed. These changes can alter its metabolomic fingerprinting, impacting further classification tasks and quality/quantitative analyses. For these reasons, the aim of this work is to compare and analyze the information obtained by different chemometric methods used in a complementary form (PCA, ASCA, and PARAFAC) to study 1H-NMR spectra variations of four red wine samples kept at different temperatures and time lapses. In conjunction, distinctive changes in the spectra are satisfactorily tracked with each chemometric method. The chemometric analyses reveal variations related to the wine sample, temperature, and time, as well as the interactions among these factors. Moreover, the magnitude and statistical significance of the effects are satisfactorily accounted for by ASCA, while the time-related effects variations are encountered by PARAFAC modeling. Acetaldehyde, formic acid, polyphenols, carbohydrates, lactic acid, ethyl lactate, methanol, choline, succinic acid, proline, acetoin, acetic acid, 1,3-propanediol, isopentanol, and some amino acids are identified as some of the metabolites which present the most important variations.

Benefits of the Light Consumption of Red Wine in Pain, Tender Points, and Anxiety in Women with Fibromyalgia: A Pilot Study. Nutrients 2023; 15:3469. [PMID: 37571406 PMCID: PMC10421395 DOI: 10.3390/nu15153469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 08/01/2023] [Accepted: 08/04/2023] [Indexed: 08/13/2023] Open
Abstract
BACKGROUND Fibromyalgia (FM) is characterized by chronic widespread pain, as well as anxiety, sadness, and depression. These symptoms are present in most patients and have a negative impact on their daily, family, and social life. The role of neurotransmitters in the pathophysiology of FM has been extensively discussed. The scientific evidence shows that levels of serotonin are decreased in patients with FM. Numerous studies support the beneficial effects that moderate wine consumption has on the body, with cardiovascular, endocrine, bone, and muscle improvements. OBJECTIVE The objective of this pilot study was to assess whether light consumption of red wine improves the main symptoms of FM. METHODS The study consisted of an experimental study with a control group with a total of 60 women diagnosed with FM following the American College of Rheumatology's criteria. The experimental group ingested 15 g of alcohol per day, in the form of red wine, over a period of four weeks. The outcome measures were: the level of pain in tender points, sadness, anxiety, depression, and quality of life. The assessments tools were: tender point graphics, the visual analogue scale (for the assessment of pain and sadness), the Hamilton Anxiety Scale, the Hamilton Depression Rating Scale, and the Fibromyalgia Impact Questionnaire. The measurements were completed before and after the consumption of red wine. In addition, the differences between groups were evaluated in terms of drug consumption in the pre-intervention and follow-up phases. RESULTS Statistically significant improvements were obtained in the wine ingestion group for the variables of pain (p = 0.038), tender points (p < 0.001), and anxiety (p = 0.028). An improvement in the mean values was observed in favor of the experimental group for the variables of sadness, depression, and quality of life. The differences observed in the changes seen in the groups that were in favor of the wine ingestion group should not be attributed to the consumption of drugs but to the fact that the experimental group had a light intake of red wine. CONCLUSIONS The results of this pilot study suggest a potential relationship between alcohol intake through the light consumption of red wine as part of the patients' diet and the improvement of the main symptoms of fibromyalgia. Future studies are necessary to confirm these preliminary data; a bigger sample and a controlled diet should be considered, and the mechanisms through which improvements are achieved should be analyzed.

Abstract
The association between socioeconomic status (SES) and alcohol-related diseases has been widely explored. Less is known, however, on whether the association of moderate drinking with all-cause mortality is modified by educational level (EL). Using harmonized data from 16 cohorts in the MORGAM Project (N = 142,066) the association of pattern of alcohol intake with hazard of all-cause mortality across EL (lower = primary-school; middle = secondary-school; higher = university/college degree) was assessed using multivariable Cox-regression and spline curves. A total of 16,695 deaths occurred in 11.8 years (median). In comparison with life-long abstainers, participants drinking 0.1-10 g/d of ethanol had 13% (HR = 0.87; 95%CI: 0.74-1.02), 11% (HR = 0.89; 0.84-0.95) and 5% (HR = 0.95; 0.89-1.02) lower rate of death in higher, middle and lower EL, respectively. Conversely, drinkers > 20 g/d had 1% (HR = 1.01; 0.82-1.25), 10% (HR = 1.10; 1.02-1.19) and 17% (HR = 1.17; 1.09-1.26) higher rate of death. The association of alcohol consumption with all-cause mortality was nonlinear, with a different J-shape by EL levels. It was consistent across both sexes and in various approaches of measuring alcohol consumption, including combining quantity and frequency and it was more evident when the beverage of preference was wine. We observed that drinking in moderation (≤ 10 g/d) is associated with lower mortality rate more evidently in individuals with higher EL than in people with lower EL, while heavy drinking is associated with higher mortality rate more evidently in individuals with lower EL than in people with higher EL, suggesting that advice on reducing alcohol intake should especially target individuals of low EL.

Abstract
Environmental issues and the sustainability of the wine industry receive widespread public attention, but few studies address the environmental impact of the circular wine industry chain. Therefore, we applied the life cycle assessment (LCA) method to a wine enterprise in Inner Mongolia, China, to conduct a cradle-to-gate assessment and comparative analysis on the linear and circular wine industry chain scenarios. The results show that the circular industry chain (S2) has better environmental benefits; the total value of each environmental impact category of S2 is reduced by more than 80% compared with that of the linear industry chain (S1). The global warming potential of S1 is decreased from 4.88 kg CO2eq to 0.919 kg CO2eq for S2. Viticulture is the primary source of environmental problems in all life cycle stages of both scenarios, and electricity and diesel consumption are the key factors affecting the results. Our study shows that the optimization of S2 significantly improves resource efficiency and energy utilization and alleviates the environmental burden through proper waste recycling. Finally, we proposed optimization suggestions based on S2. This study provides scientific guidance for promoting the wine industry to build a circular industry chain and optimize the industrial structure, thus promoting the sustainable development of the industry.

Abstract
BACKGROUND In the search of tools to deal with climate change-related effects along with the aim of avoiding the loss of aromatic typicity in wine, two native yeasts strains of Saccharomyces cerevisiae (CLI 271 and CLI 889) were evaluated to determine their influence on white Malvasia aromatica wines aroma composition and sensory characteristics. METHODS The strains were tested versus a commercial yeast strain (LSA). The fermentations were performed on grape must of the Malvasia aromatica variety previously macerated. Wine quality was studied by analysis of oenological parameters together with volatile aroma components using gas chromatography coupled to flame ionization detector (GC-FID) to quantify major volatiles compounds and headspace-solid phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME/GC-MS) to determine terpenoids and C13-norisoprenoids. Sensorial analysis was also realized by an experienced taster panel. RESULTS Wines from locally-selected yeasts strains used had lower volatile acidity levels and higher concentration of aromatic compounds compared to the commercial strain ones. The yeast strain S. cerevisiae CLI 271 provided wines with a higher concentration of esters related to fruity attributes, especially isoamyl acetate. The tasting panel highlighted the strong floral character of wines from S. cerevisiae CLI 889 fermentation. CONCLUSIONS The use of microorganisms well adapted to climatic conditions can be used to produce quality wines of the Malvasia aromatica variety.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rehmanniae Radix Praeparata (RRP), the processed root of Rehmannia glutinosa, has been widely used to treat Yin deficiency syndrome in traditional Chinese medicine. RRP is available in two forms: processed by steaming with water (SRR) or processed by stewing with yellow rice wine (WRR). Previous work has documented chemical differences in the secondary metabolomes and glycomes of SRR and WRR. AIM OF THE STUDY This study aimed to compare SRR and WRR in terms of Yin-nourishing effects via metabolomics and microbiome analysis. MATERIALS AND METHODS ICR mice were orally administered with thyroxine for 14 d to induce Yin deficiency. Changes in biochemical indices and histopathology were detected. Serum metabolomics analysis and microbial 16S rRNA sequencing were performed to compare the therapeutic effects and mechanisms between SRR and WRR in treating thyroxine-induced Yin deficiency. RESULTS Both SRR and WRR decreased serum T3, T4 and MDA levels, and increased SOD activity. SRR more effectively decreased serum Cr, and ameliorated kidney injury, while WRR showed better regulation on ratio of cAMP/cGMP and serum TSH, and relieved thyroid injury. Both SRR and WRR regulated tyrosine, glycerophospholipid, and linoleic acid metabolism and the citric acid cycle. Additionally, SRR regulated fatty acid metabolism, while WRR influenced alanine, aspartate and glutamate metabolism, and bile acid biosynthesis. SRR significantly enriched the genera Staphylococcus and Bifidobacterium in the gut microbiome, while WRR significantly enriched the genera Akkermansia, Bacteroides and Parabacteroides, and decreased the abundance of Lactobacillus. CONCLUSIONS SRR displayed better protective effects on kidney, while WRR showed stronger effects on thyroid in thyroxine-induced Yin deficient mice. These differences might be due to different regulating effects of SRR and WRR on the metabolome and gut microbiota.

Abstract
Chimerism is the phenomenon when several genotypes coexist in a single individual. Used to understand plant ontogenesis they also have been valorised through new cultivar breeding. Viticulture has been taking economic advantage out of chimeras when the variant induced an important modification of wine type such as berry skin colour. Crucial agronomic characters may also be impacted by chimeras that aren't identified yet. Periclinal chimera where the variant has entirely colonised a cell layer is the most stable and can be propagated through cuttings. In grapevine, leaves are derived from both meristem layers, L1 and L2. However, lateral roots are formed from the L2 cell layer only. Thus, comparing DNA sequences of roots and leaves allows chimera detection. In this study we used new generation Hifi long reads sequencing, recent bioinformatics tools and trio-binning with parental sequences to detect periclinal chimeras on 'Merlot' grapevine cultivar. Sequencing of cv. 'Magdeleine Noire des Charentes' and 'Cabernet Franc', the parents of cv. 'Merlot', allowed haplotype resolved assembly. Pseudomolecules were built with a total of 33 to 47 contigs and in few occasions a unique contig for one chromosome. This high resolution allowed haplotype comparison. Annotation was transferred from PN40024 VCost.v3 to all pseudomolecules. After strong selection of variants, 51 and 53 'Merlot' specific periclinal chimeras were found on the Merlot-haplotype-CF and Merlot-haplotype-MG respectively, 9 and 7 been located in a coding region. A subset of positions was analysed using Molecular Inversion Probes (MIPseq) and 69% were unambiguously validated, 25% are doubtful because of technological noise or weak depth and 6% invalidated. These results open new perspectives on chimera detection as an important resource to improve cultivars through clonal selection or breeding.

Abstract
Muscadine wine has a unique polyphenol profile consisting of anthocyanins, ellagic acids, and flavonols. This study aims to compare the prevention, treatment, and combined activity (P + T) of dealcoholized muscadine wine (DMW) on DSS-induced colitis in mice and its impact on the gut microbiome. Male C57BL/6 mice in the healthy and colitis group received an AIN-93M diet for 28 days. In the prevention, treatment, and P + T (prevention + treatment) groups, mice received an AIN-93M diet containing 2.79% (v/w) DMW on days 1-14, 15-28, and 1-28, respectively. Except for mice in the healthy group, all mice were given water with 2.5% (w/v) DSS on days 8-14 to induce colitis. DMW in all three receiving groups reduced myeloperoxidase activity, histology scores, and phosphorylation of Iκb-α in the colon. Colon shortening, serum IL-6, and colonic mRNA of TNF-α were blunted only in the P + T group. Gut permeability was reduced in the treatment and P + T groups. DMW in P + T group showed higher activity to increase microbiome evenness, modulate β-diversity, elevate the cecal content of SCFAs, and enrich SCFA-producing bacteria, including Lactobacillaceae, Lachnospiraceae, Ruminococcaceae, and Peptococcaceae. This was accompanied by a decrease in pathogenic Burkholderiaceae in mice. This study suggests that muscadine wine has partial preventive and therapeutic effects against inflammatory bowel disease. The combination of prevention and treatment using DMW showed better activities than either prevention or treatment.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Curculigo orchioides Gaertn. (CO), a traditional Chinese herb recorded in Chinese Pharmacopoeia, can nourish kidney yang, strengthen bones, and dispell cold-dampness. Raw CO (rCO) and wine-processed CO (pCO), the main processed products of CO for clinical application, show differences in nourishing kidney yang and ameliorate osteoporosis. However, the difference in efficacy and mechanism of rCO and pCO on bone destruction in rheumatoid arthritis (RA) remain unclear. AIM OF THE STUDY To compare the pharmacodynamics of rCO and pCO in the treatment of bone destruction in RA and to reveal the potential mechanism by which rCO and pCO exert effects by metabolomics approach. MATERIALS AND METHODS Ultra-high performance liquid chromatography Q exactive mass spectrometry (UHPLC-Q-Exactive-MS) combined with multivariate data analysis was applied to identify the differential chemical components in rCO and pCO. Collagen-induced arthritis (CIA) rats were orally administrated with different doses of rCO and pCO for 4 weeks. The body weight, paw swelling, arthritis scores, serum inflammatory cytokines concentration, knee tumor necrosis factor (TNF)-α, interleukin (IL)-6 protein levels, and inflammatory cell infiltration were determined to investigate the effects of rCO and pCO on arthritic symptoms and inflammatory responses in CIA rats. The effects of rCO and pCO on bone destruction were assessed using safranin O-fast green and tartrate-resistant acid phosphatase (TRAP) staining, immunohistochemical analysis of osteoprotegerin (OPG) and receptor activator of nuclear factor-κB ligand (RANKL) proteins, and micro-computed tomography (micro-CT) in rats. In addition, metabolomics was performed to explore the mechanism of rCO and pCO against bone destruction in RA. RESULTS A total of 41 chemical constituents were identified in both rCO and pCO, 9 of which were screened out as discriminatory compounds. According to the pharmacodynamic assays, pCO exhibited a stronger effect than rCO in attenuating the severity of arthritis, reducing inflammation, and inhibiting bone destruction. The metabolomics results showed that pentose phosphate pathway was the key metabolic pathways regulated by rCO, while pCO regulated multiple metabolic pathways including phenylalanine metabolism pathways, phenylalanine, tyrosine and tryptophan biosynthesis, taurine and hypotaurine metabolism, and glycerophospholipid metabolism pathways. CONCLUSION pCO displayed a better effect on alleviating bone destruction in RA was than rCO. This might be associated with that pCO can decrease inflammation in RA through regulating more metabolism pathways.

Abstract
Saccharomyces kudriavzevii is a cold-tolerant species identified as a good alternative for industrial winemaking. Although S. kudriavzevii has never been found in winemaking, its co-occurrence with Saccharomyces cerevisiae in Mediterranean oaks is well documented. This sympatric association is believed to be possible due to the different growth temperatures of the two yeast species. However, the mechanisms behind the cold tolerance of S. kudriavzevii are not well understood. In this work, we propose the use of a dynamic genome-scale model to compare the metabolic routes used by S. kudriavzevii at two temperatures, 25°C and 12°C, to decipher pathways relevant to cold tolerance. The model successfully recovered the dynamics of biomass and external metabolites and allowed us to link the observed phenotype with exact intracellular pathways. The model predicted fluxes that are consistent with previous findings, but it also led to novel results which we further confirmed with intracellular metabolomics and transcriptomic data. The proposed model (along with the corresponding code) provides a comprehensive picture of the mechanisms of cold tolerance that occur within S. kudriavzevii. The proposed strategy offers a systematic approach to explore microbial diversity from extracellular fermentation data at low temperatures. IMPORTANCE Nonconventional yeasts promise to provide new metabolic pathways for producing industrially relevant compounds and tolerating specific stressors such as cold temperatures. The mechanisms behind the cold tolerance of S. kudriavzevii or its sympatric relationship with S. cerevisiae in Mediterranean oaks are not well understood. This study proposes a dynamic genome-scale model to investigate metabolic pathways relevant to cold tolerance. The predictions of the model would indicate the ability of S. kudriavzevii to produce assimilable nitrogen sources from extracellular proteins present in its natural niche. These predictions were further confirmed with metabolomics and transcriptomic data. This finding suggests that not only the different growth temperature preferences but also this proteolytic activity may contribute to the sympatric association with S. cerevisiae. Further exploration of these natural adaptations could lead to novel engineering targets for the biotechnological industry.

Abstract
Small structural differences bring great difficulties on carbohydrates identification, especially in terms of their quantification. Herein, a novel ESI-MS/MS based strategy was established to discriminate and relatively quantified protonated PMP-disaccharides with different composition and glycosidic bond. Interestingly, protonated PMP labeled-disaccharides provided abundant fragment ions arising from cross-ring cleavage and glycosidic bond cleavage, which could afford diagnostic fragment patterns for isomers differentiation in combination of statistical analysis. It was worth to note that the relative intensity ratios (RIR) of three ion pairs could completely discriminate 16 disaccharides, and subsequently used to relatively quantified isomers in a binary mixture. Ultimately, this method was applied for the discrimination of yellow rice wine, and then the relative content of maltose and isomaltose were confirmed as well. In general, this method was easy to operation and effective for rapid differentiation and quantification of isomeric disaccharides in complex matrices.

Abstract
Applied sciences have increased focus on omics studies which merge data science with analytical tools. These studies often result in large amounts of data produced and the objective is to generate meaningful interpretations from them. This can sometimes mean combining and integrating different datasets through data fusion techniques. The most strategic course of action when dealing with products of unknown profile is to use exploratory approaches. For omics, this means using untargeted analytical methods and exploratory data analysis techniques. The current study aimed to perform data fusion on untargeted multimodal (negative and positive mode) liquid chromatography-high-resolution mass spectrometry data using multiple factor analysis. The data fusion results were interpreted using agglomerative hierarchical clustering on biplot projections. The study reduced the thousands of spectral signals processed to less than a hundred features (a primary parameter combination of retention time and mass-to-charge ratios, RT_m/z). The correlations between cluster members (samples and features from) were calculated and the top 10% highly correlated features were identified for each cluster. These features were then tentatively identified using secondary parameters (drift time, ion mobility constant and collision cross-section values) from the ion mobility spectra. These ion mobility (secondary) parameters can be used for future studies in wine chemical analysis and added to the growing list of annotated chemical signals in applied sciences.

Abstract
In the wine industry, grape processing is accompanied by waste generation, such as grape stalks, winery wastewater, and grape pomace (GP). GP can be used to produce value-added compounds such as medium-chain carboxylic acids (MCCA). This work aimed to determine the operational conditions (temperature, addition of nutrients, and initial waste concentration) to improve MCCA production using waste GP from the winery industry as a substrate. The electron donor (ethanol) and electron acceptor (acetate) were directly generated from the GP and consecutively used to produce MCCA. The treatment with high concentration, temperature, and nutrient addition promotes caproic acid's maximal yield and concentration (0.11 ± 0.02 g MCCA/g TS). Nutrients' presence and temperature significantly affected electron acceptor production. The addition of nutrients and 30 °C leads to elevated acetate production. However, at 37 °C, butyrate and MCCA were mainly produced without adding nutrients, and high ethanol consumption was observed. A higher metabolic diversification was observed at 37 °C than at 30 °C. Temperature and nutrient availability significantly affected the metabolic pathway and the type of carboxylic acid produced.

Abstract
This study aimed to mitigate the adverse effects of global warming by applying severe shoot topping (SST) to grapevines in a semi-arid climate. A three-year study (2018-2020) was performed to investigate the impact of SST on wine flavor composition. Results showed that SST effectively delayed the grape harvest date, which was more evident in the dry and warm vintage (7-11 d). SST significantly increased the concentration of myricetin-based flavonols in wines which were 18% higher than in untreated wines. Through orthogonal partial least squares discriminant analysis (OPLS-DA), SST wines were characterized by more abundant phenolic compounds and higher sensory scores. The carry-over effect of applying SST in consecutive years in the same vines could be reflected in wine color. The correlations among wine metabolites, color and aroma parameters, and sensory parameters were evaluated through multiple analyses. This study provided an idea for delaying grape ripening in a semi-arid climate.

Abstract
Grapes are widely cultivated around the world and their quality has distinct regional characteristics. In this study, the qualitative characteristics of the 'Cabernet Sauvignon' grape variety in seven regions, from half-véraison to maturity, were analyzed comprehensively at physiological and transcriptional levels. The results indicated that the quality traits of 'Cabernet Sauvignon' grapes in different regions were significantly different with obvious regionality. Total phenols, anthocyanins, and titratable acids were the main factors of the regionality of berry quality, which were very sensitive to changes in the environment. It should be noted that the changes in titrating acids and total anthocyanin of berries vary greatly from half-véraison to maturity between regions. Moreover, the transcriptional analysis showed that the co-expressed genes between regions characterized the core transcriptome of berry development, while the unique genes of each region reflected the regionality of berries. The differentially expressed genes (DEGs) between half-véraison and maturity can be used to demonstrate that the environment of the regions could promote or inhibit gene expression. The functional enrichment suggested that these DEGs help to understand the interpretation of the plasticity of the quality composition of grapes according to the environment. Taken together, the information generated by this study could contribute to the development of viticultural practices aimed at making better use of native varieties for the development of wines with regional characteristics.

Abstract
OBJECTIVES Corni Fructus is one of the most famous traditional Chinese medicines (TCMs) for the treatment of various chronic kidney diseases. Wine-processed Corni Fructus (WCF) is the main processed form of Crude Corni Fructus (CCF). In this study, potential mechanisms of action of CCF and WCF on chronic renal failure (CRF) model were developed to explore wine-processed mechanism of Corni Fructus. METHODS An integrated strategy combining metabolomics, network analysis and bioinformatics analysis has been established to investigate the therapeutic mechanisms of WCF and CCF in rats with CRF. KEY FINDINGS The histopathological results showed that both WCF and CCF improved kidney injury and dysfunction of CRF rats, but WCF was more effective than CCF. Metabolic pathway analysis indicated that 24 metabolites and 5 major disturbed pathways associated with CCF, while WCF regulated 27 metabolites and 2 metabolic pathways. Bioinformatic analysis and network analysis revealed that 8 genes and 7 genes were regulated by CCF and WCF on CRF rats, respectively. The quantitative real-time polymerase chain reaction experiments verified the regulatory ability of CCF and WCF on the expression of 4 genes. CONCLUSIONS An integrated strategy combined metabolomics, network analysis and bioinformatics was established to provide valuable holistic insight to explore the processing mechanism of TCMs.

Abstract
In this work, reduction of alcoholic strength was discussed as a means to reduce consumption and alcohol-attributable harm. Statistical modelling was conducted to (1) estimate its potential for the largest six Western and Central European countries (France, Germany, Italy, Poland, Spain, UK); (2) calculate the increase in taxation necessary to reach this potential, and (3) estimate the mortality gains achieved with the introduction of no- or low-alcohol beverages in the UK and Spain. The high public health potential of reducing alcoholic strength was demonstrated via modelling a scenario in which the strength of all beverages was reduced by 10%, which would avert thousands of deaths in these six European countries per year. However, methods by which to achieve these gains were not clear, as the alcohol industry has shown no inclination toward reductions in the alcoholic strength of beer, wine, or spirits via a reformulation on a large scale. The increase of excise taxation to achieve the public health gains of such a reduction would result in markedly increasing prices-a situation unlikely to be implemented in Europe. Finally, the introduction of beer and wine with an alcoholic strength below 0.5% led to some substitutions of higher-strength beverages, but did not show a marked public health impact. New taxation initiatives to achieve the potential of a reduction of alcoholic strength will need to be implemented.

Abstract
Anthocyanins are flavonoids that contribute to the color of grape berries and are an essential component of grape berry and wine quality. Anthocyanin accumulation in grape berries is dependent on the coordinated expression of genes encoding enzymes in the anthocyanin pathway that are principally regulated at the transcriptional level, with VvMYBA1 as the main transcriptional regulator in grapes. Alternative splicing (AS) events in VvMYBA1, however, have not been examined. In the present study, VvMYBA1-L, an AS variant of VvMYBA1, was identified in 'ZhongShan-Hong' (ZS-H) and its offspring. The AS variant is characterized by a deletion in the third exon of the open reading frame (ORF) of VvMYBA1-L, resulting in the early termination of the encoded protein. Overexpression of VvMYBA1-L in grape berries resulted in delayed flesh coloration and ectopic overexpression of VvMYBA1-L in tobacco inhibited the coloration of petals. Yeast two-hybrid and bimolecular fluorescence complementation (BiFC) assays revealed that VvMYBA1-L interacts with VvMYBA1. Dual luciferase assays indicated that co-infiltration of VvMYC1 and VvMYBA1 significantly activated the promoter regulated expression of VvCHS3, VvDFR, VvUFGT, and VvF3H. In the presence of VvMYBA1-L, however, the induction effect of VvMYBA1 on the indicated promoters was significantly inhibited. Our findings provide insight into the essential role of VvMYBA1 and its variant, VvMYBA1-L, in regulating anthocyanin accumulation in grape berry flesh.

Abstract
Evaluating the potential climatic suitability for premium wine production is crucial for adaptation planning in Europe. While new wine regions may emerge out of the traditional boundaries, most of the present-day renowned winemaking regions may be threatened by climate change. Here, we analyse the future evolution of the geography of wine production over Europe, through the definition of a novel climatic suitability indicator, which is calculated over the projected grapevine phenological phases to account for their possible contractions under global warming. Our approach consists in coupling six different de-biased downscaled climate projections under two different scenarios of global warming with four phenological models for different grapevine varieties. The resulting suitability indicator is based on fuzzy logic and is calculated over three main components measuring (i) the timing of the fruit physiological maturity, (ii) the risk of water stress and (iii) the risk of pests and diseases. The results demonstrate that the level of global warming largely determines the distribution of future wine regions. For a global temperature increase limited to 2°C above the pre-industrial level, the suitable areas over the traditional regions are reduced by about 4%/°C rise, while for higher levels of global warming, the rate of this loss increases up to 17%/°C. This is compensated by a gradual emergence of new wine regions out of the traditional boundaries. Moreover, we show that reallocating better-suited grapevine varieties to warmer conditions may be a viable adaptation measure to cope with the projected suitability loss over the traditional regions. However, the effectiveness of this strategy appears to decrease as the level of global warming increases. Overall, these findings suggest the existence of a safe limit below 2°C of global warming for the European winemaking sector, while adaptation might become far more challenging beyond this threshold.

Abstract
The main aim of this study was to perform a combined life cycle assessment and life cycle costing of the most used wine packaging systems in Italy. Packaging plays a key role in food and beverage production and supply chain, but the increasing volume of packaging used causes many environmental concerns. The wine sector is no exception, especially in Italy that is the largest producer in the world. Eight packaging alternatives were compared in environmental and economic terms assuming a functional unit of three litres and a cradle to grave approach: one aseptic carton system, two bag-in-box systems, two PET bottle systems, and three glass bottle systems. The results were analysed with an eco-efficiency portfolio approach. There was consistency between the LCA and LCC results for most of the packaging systems. From both the environmental and economical point of views, aseptic cartons and bag-in-box systems were the most sustainable alternatives, while the glass systems had the worst global performances due to the high weight and consequent huge energy consumption during bottle production. The size of the containers was the key factor that most affected the results both in environmental and economic terms.

Abstract
When talking about environmental and sustainability topics, the wine sector plays a fundamental role ensuring that wine remains not only economically but also environmentally sustainable, hence the importance of conducting analyses to measure the impact of food production through Life Cycle Assessment tool. This paper aims to propose a systematic review of the LCA studies related to the grape and wine production chain providing both a qualitative and a quantitative analysis of methodologies used, and results proposed, as well as focusing the attention on carbon and water environmental indicators that can be evaluated using the LCA tool. Both the qualitative and the quantitative analysis showed a strong variability among the studies starting from the selection of the functional unit till the way the impact assessment is carried out. The results indicated the lack of homogeneity on the application of the LCA, emphasizing the need for deeper research on the wine sector. Based on the interpretation of the results, it was possible to identify the main drivers and barriers of the environmental impact assessment, allowing the contribution towards providing insights both for LCA practitioners and stakeholders of the wine sector. To this end, the main novelty of this work was to give an all-around view of the application of LCA tool in the wine sector providing a first step in the creation of a standardized procedure that harmonize the way a LCA study must be done. This opportunity would be a huge advantage for the scientific community, allowing the possibility to compare different wine production realities by using a globally recognized procedure without bias. Future research will have to focus on understanding and developing this scheme for enhancing the added value of the wine product.

Abstract
The purpose of this study was to investigate differences in the pharmacodynamic, pharmacokinetic, and kidney distribution between Ligustri Lucidi Fructus (LLF) and wine-steamed Ligustri Lucidi Fructus (WLL) extracts in diabetic nephropathy (DN) rats. The DN rats were induced by high-fat-sugar diet (HFSD)/streptozotocin (STZ) regimen. For pharmacodynamics, the DN rats were treated with LLF and WLL extracts to assess the anti-diabetic nephropathy effects. For pharmacokinetics and kidney distribution, the concentrations of drugs (hydroxytyrosol, salidroside, nuezhenidic acid, oleoside-11-methyl ester, specnuezhenide, 1‴-O-β-d-glucosylformoside, G13, and oleonuezhenide) were determined. Regarding the pharmacodynamics, LLF and WLL extracts decreased the levels of blood glucose, serum creatinine (SCr), blood urea nitrogen (BUN), and 24-h urinary protein (24-h Upro) in DN rats. Furthermore, LLF and WLL extracts increased the level of high-density lipoprotein cholesterol (HDL-C); decreased the levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C); and reduced levels of pro-inflammatory cytokines (IL-1β, TNF-α, and IL-6) in DN rats. The anti-diabetic nephropathy effect of the WLL extract was better than that of the LLF extract. Regarding the pharmacokinetic and kidney tissue distribution, there were obvious differences in the eight ingredients between LLF and WLL extracts in DN rats. LLF and WLL extracts had protective effects on DN rats, while the WLL extract was better than the LLF extract regarding anti-diabetic nephropathy effects. The pharmacokinetic parameters and kidney distribution showed that wine-steaming could affect the absorption and distribution of the eight ingredients. The results provided a reasonable basis for the study of the clinical application and processing mechanism of LLF.
