The urinary system Degrees of SARS-CoV-2 Nucleocapsid Proteins Escort Likelihood of AKI as well as COVID-19 Seriousness: Any Single-Center Observational Research.
In this study, protein isolate was prepared from Baltic herring (Clupea harengus membras) using alkaline pH-shift process. The aim of this research was to characterize the protein isolate and to study its potential in food models. A special focus was placed on characterization of odour profile and volatile compounds contributing to the odour profile of the protein isolate using gas chromatography - olfactometry. 2,3-Pentanedione, hexanal, 4(Z)-heptenal, 2,4(E,E)-nonadienal, and three compounds tentatively identified as 1,5(E)-octadien-3-ol, 1,5(Z)-octadien-3-ol, and 1,5(Z)-octadien-3-one were the most important odour-contributing compounds in the protein isolate (Nasal Impact Factor 83-100%, intensity 2.6-3.3 on a scale 0-4). 2-Methylpropanal, 2- and 3-methylbutanal, and three unknown compounds were less intense in the protein isolate than in the raw material, which might have contributed to the lower intensity of fishiness observed for the protein isolate (2.2 vs 3.3 on a scale 0-4). Surimi-type gels prepared from the Baltic herring protein isolate had texture properties (hardness and cohesiveness) similar to those of commercial products. Due to the abundancy of dark muscle tissue in Baltic herring, the protein isolate had a significantly lower whiteness (W = 63) compared to the commercial surimi products (W = 80-83). Increasing the solubilisation or precipitation pH did not improve the whiteness, but resulted in significantly softer, less cohesive, and less chewy gels. The findings of this study indicate that alkaline-based pH-shift processing is a potential way to increase the food application of Baltic herring.In this study the effect of farming practices on the diversity of grape fungal community of Vitis vinifera L. cultivar Montepulciano and the microbial metabolic activity was investigated. Small-scale vinifications were performed and wines were characterized. Agronomic management system affected the fungal community composition. Hanseniaspora, Areobasidium and Botrytis genera represented 30%, 20% and 10% of the total reads in all samples. A. pullulans, and Cladosprium cladosporioides mainly occurred on organic and biodynamic grapes. Saccharomyces and Pseudopithomyces genera were present only on organic or biodynamic grapes, respectively. The agronomic managements also influenced the potential functionality of microbial community. In fact, the metabolic function was increased in organic and biodynamic grapes. Polymers were used only by organic and biodynamic microbial communities, which also showed the highest values of Shannon's diversity index, and substrate richness. However, no significative differences were observed for the oenological parameters analyzed, with the only exception of the content of sugars which were higher on conventional grapes. The fermentation profiles showed that conventional wines had a lower residual sugars content, and a higher amount of alcohol. The differences observed in the volatile composition of the wines were both quantitative and qualitative. Conventional wines showed a lower content of esters, and a higher concentration of alcohols than organic and biodynamic ones. Biodynamic wines were characterized by the highest content of organic acids. The obtained results revealed that farming practices shape the fungal community influencing wine traits linking the wine with the viti-vinicultural area of origin.Pseudostellaria heterophylla, has historically been used as medicine food homology plant for thousand years in China. Our previous studies had indicated that daily intake of Pseudostellaria heterophylla extract enhanced cognitive memory. Herein, heterophyllin B (HET-B), a brain permeable cyclopeptide from Pseudostellaria heterophylla was determined, and the molecular mechanism underlying its memory improvement effects was investigated. Pseudostellaria heterophylla extract as well as HET-B reversed Aβ25-35-induced axonal atrophy and neuronal apoptosis in cultured cortical neurons of mice. HET-B could enhance memory retrieval, modulate splenic T helper cell, and ameliorate neuroinflammation in i.c.v. Aβ1-42 injected Alzheimer's disease (AD) mice. Bcl-2 protein To explore the mechanism of action, network pharmacology was performed to predict protein targets and pathways of HET-B against AD. Five key targets were identified related to the effect of HET-B in AD intervention, and were clarified involved in axonal regeneration. We revealed for the first time that HET-B promoted memory retrieval through axonal regeneration and anti-neuroinflammation. This study provides a basis to research on HET-B as nutritional supplements for brain healthy.After thousands of years of evolution and development, traditional fermented soybean foods, with their unique charm, have gained a stable place in the global market. With the explosive development of modern biological technologies, some traditional fermented soybean foods that possess health-promoting benefits are gradually appearing. Physiologically active substances in fermented soybean foods have received extensive attention in recent decades. This review addresses the potential health benefits of several representative fermented soybean foods, as well as the action mechanism and influencing factors of their functional components. Phenolic compounds, low-molecular-weight peptides, melanoidins, furanones and 3-hydroxyanthranilic acid are the antioxidative components predominantly found in fermented soybean foods. Angiotensin I-converting enzyme inhibitory peptides and γ-aminobutyric acid isolated from fermented soy foods provide potential selectivity for hypertension therapy. The potential anti-inflammatory bioactive components in fermented soybean foods include γ-linolenic acid, butyric acid, soy sauce polysaccharides, 2S albumin and isoflavone glycones. Deoxynojirimycin, genistein, and betaine possess high activity against α-glucosidase. Additionally, fermented soybean foods contain neuroprotective constituents, including indole alkaloids, nattokinase, arbutin, and isoflavone vitamin B12. The anticancer activities of fermented soybean foods are associated with surfactin, isolavone, furanones, trypsin inhibitors, and 3-hydroxyanthranilic acid. Nattokinase is highly correlated with antioxidant activity. And a high level of menaquinones-7 is linked to protection against neurodegenerative diseases. Sufficiently recognizing and exploiting the health benefits and functional components of traditional fermented soybean foods could provide a new strategy in the development of the food fermentation industry.Starch-guest inclusion complexes (ICs) are a novel, clean-label flavor encapsulation system with the potential to improve stability of aroma volatiles. While amylase has been shown to modulate guest release in vitro, release by sensory perception has not been evaluated. Here, Temporal Check-All-That-Apply (TCATA) and CATA were used to compare flavor perception of starch-limonene ICs to uncomplexed limonene, and the differences in perception were explored as a function of participant salivary α-amylase activity (sAA) and salivary flow rate (sFR). High sFR levels decreased limonene perception while high sAA increased limonene perception, highlighting the potential influence of these physiological factors on flavor perception of foods. Temporal flavor perception of a chewing gum containing starch-limonene ICs and a second chewing gum containing uncomplexed limonene and corn starch (CTL) was evaluated by 99 untrained consumers who assessed taste, texture, and aroma attributes over 17 min by TCATA and CATA. In addition, participants were segmented into three clusters based on their sAA and sFR, and cluster TCATA curves for each sample and attribute were statistically compared. Overall, participants rated Citrus, Sour and Bitter (p less then 0.05) significantly higher for the IC sample and rated Sweet higher for the CTL. For Citrus, Sour, and Bitter, significant differences were observed between the three clusters for the IC chewing gum, while the CTL gum showed no significant differences for these three attributes. We demonstrate that flavor perception of starch-guest ICs varies with participants' salivary α-amylase activity and flow rate. Additionally, TCATA and CATA were found to be well suited to characterize flavor release systems over a long period of time as multiple flavor percepts can be simultaneously tracked.Bee pollen as a plant-derived food is consumed as nutritional/functional supplements by humans. But it might confer foodborne allergenicity in susceptible populations, limiting its extensive application. In this study, five potential allergens including profilin, cystatin, prolamin, expansin, and alcohol dehydrogenase in bee pollen derived from Brassica campestris (BP-Bc), were identified through mass spectrometry-based proteomic analysis. Moreover, different types of enzymes (cellulases, pectases, and papains) serve biological roles in pollen wall breaking and expansion, but also promote allergen release and degradation. Proteomic analysis showed that profilin, cystatin, and alcohol dehydrogenase were significantly reduced in BP-Bc following joint treatment with three enzymes. Metabolomic characterization of potential enzymatic hydrolysates of these significantly-decreased allergens was performed, which showed nine major oligopeptides and six amino acids at significantly higher levels in the enzyme-treated BP-Bc. These findings clarified the culprit responsible for bee pollen allergy and the mechanism of enzymatic desensitization for its further development.Dry cleaning activities such as brushing, scraping, and vacuuming have been widely used in low-moisture food production. However, the impact that product compositional differences and time between cleaning cycles have on the ease of food particulate removal is unclear. In our study, fruit powders were deposited on stainless-steel coupons, then removed using a hygienic brush. The residence time was defined as the duration between fruit powder deposition and attempted removal. Longer residence time resulted in elevated water activity (aw), which decreased the degree of removal for most fruit powders other than pumpkin powder and apple powder (sieve size 2.36 mm). For instance, the aw of peach powder increased from 0.59 ± 0.01 on day 1 to 0.64 ± 0.01 on day 7, and residual powder after cleaning increased from 86.12 ± 1.73% to 93.26 ± 2.12% from day 1 to day 7. Peach powder and apple/pear/plum powder were the most difficult to remove, with average residual powder of 92.79 ± 4.97% and 58.41 ± 11.41%, respectively. Fruit powders that were more difficult to remove also exhibited higher cohesion and adhesion. For example, the cohesion and adhesion of peach powder at 76% relative humidity for 3 days were 4479.53 ± 681.86 N/m2 and 1347.53 ± 439.15 N/m2, respectively. By contrast, the cohesion and adhesion of pumpkin powder at 76% relative humidity for 3 days were only 102.34 ± 93.80 N/m2 and 90.64 ± 36.52 N/m2, respectively. These results suggested that aw could significantly influence the brush cleaning outcome in a manner that was dependent on the identity of the fruit powder.The usage of traditional crafts during the fermentation process has a great influence on the quality of Jiang-flavored Daqu. This study focused on exploring the impacts of traditional crafts on Daqu microecology through high-throughput sequencing and statistical analyses. These results show that traditional crafts modulated microbial community succession through the regulation of temperature, moisture, and acidity. High temperatures (66 ± 1 °C) were conducive to the growth of microbes that produced flavor compounds, such as Bacillus and Thermoactinomyces. Low moisture content (correlated with 22 genera) and high acidity (8 genera) were mainly responsible for the decreased microbial diversity. Two flipping processes showed significant effects on the internal microecology and microbial metabolism. The first flip of Daqu may assist in regulating the microbial community structure and promoting the enrichment of flavor-functional microorganisms. The second flipping was reasonable for the enrichment of esterifying functional microorganisms, thus enhancing the esterifying power of Daqu with reduced acidity.
