Soaking is a crucial process in adjusting initial fermentation acidity and achieving desired flavor quality of rice wines. Effects of soaking time on physicochemical characteristic of rice, flavor profiles, microbial community and sensory characteristic of Huangjiu were investigated. Soaking caused significantly changes in amylopectin content, and rice with high amylopectin content was conducive to produce esters and aldehydes during Hungjiu brewing. High-throughput sequencing showed that bacteria types were more abundant than fungi during brewing, suggesting that bacterial community might be primarily responsible for Huangjiu flavor. Differential analysis revealed that Weissella and Enterobacter contributed greatly to the accumulation of alcohols, esters and aldehydes during Huangjiu brewing, while Clostridium, Acinetobacter, Cyanobacteria, Zymomonas and Exiguo-bacterium were responsible for the rancidity. Based on spearman’s correlation analysis, Lactococcus, Weissella, Pediococcus, Lactobacillus and Staphylococcus were the key microbial genera responsible for the flavor characteristic of Huangjiu. While favorable soaking caused an increased intensity in alcohol-aroma, full body and continuation of resultant Huangjiu, insufficient soaking led to a higher intensity of bitter taste. Summarily, soaking acidity ranged from 2 to 3 g/L was beneficial for preventing rancidity and improving the production of flavor compounds in Huangjiu.

Application of 702-23-8, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 702-23-8 is helpful to your research.

In this study, polyvinyl alcohol (PVA) gel beads were used to aid the partial nitrification and anammox process (PN/A) for treating low-strength ammonia wastewater. When treating synthetic and municipal wastewater, the reactor amended with PVA gel beads achieved a total nitrogen removal efficiency of 75.1 +/- 8.4% and 66.6 +/- 7.0% respectively, while the control reactor without PVA gel beads achieved 63.2 +/- 7.8% and 28.2 +/- 11.5% respectively. Dissolved oxygen (<0.5 mg O-2 L-1) and substrate diffusion in porous PVA gel beads facilitated the formation of microbial stratification in the gel beads. Unclassified Candidatus Brocadiaceae (major anammox bacteria) and Ignavibacterium (major ammonia oxidizing bacteria) enriched in the inside and outside layers of PVA gel beads, which benefited the synergetic cooperation of these bacteria and protecting them from environmental fluctuations. This study provides a promising solution for achieving a reliable PN/A process in mainstream wastewater treatment.

Osteopontin (OPN) is a multifunctional protein present in different tissues, body fluids and milk. Different milk has different level of OPN content. To determine the amount of osteopontin in bovine, buffalo, yak, sheep and goat milk, we developed an ultra-high performance liquid chromatography tandem mass spectrometry (UHPLCMS/MS) method to detect an osteopontin signature peptide. The signature peptides selected by searching Uniprot database for trypsin digested osteopontin. The sample preparation procedure includes trypsin digestion, dimethyl labeling of tryptic peptides, purification and concentration of labeled tryptic peptide with solid phase extraction. The limit of detection and limit of quantification are 0.5 mg L-1 and 2.0 mg L-1, respectively. The method has satisfactory analytical performance with a linearity of R-2 >= 0.998, recoveries of 103.7-111.0%, and precision of 1.8-6.2%. It is also validated and successfully applied to quantifying osteopontin content in bovine, buffalo, yak, sheep and goat milk.

Purpose: Studies have shown that men with Peyronie’s disease often suffer from psychological problems, but the psychiatric burden of this disorder remains largely unknown. We assessed risks of a range of psychiatric outcomes in a population based Swedish cohort comprising 3.5 million men. Materials and Methods: We conducted a longitudinal cohort study based on Swedish national registers. A total of 8,105 men diagnosed with Peyronie’s disease and 3.5 million comparison subjects from the general Swedish population were selected, and followed up with for diagnosed psychiatric outcomes including substance use disorder, alcohol misuse, anxiety disorder, depression, and self-injurious behaviors. Risks of psychiatric outcomes were estimated with Cox regressions and additionally adjusted for birth year. Results: Men with Peyronie’s disease had increased risks of being diagnosed with substance use disorder (HR 1.4, 95% CI 1.1-1.9), no excess risk of alcohol misuse (HR 0.9, CI 0.8-1.1), but elevated risks of anxiety disorder (HR 1.9, CI 1.6-2.2), depression (HR 1.7, CI 1.5-2.0), self-injurious behaviors (HR 2.0, 95% CI 1.7-2.3) as well as any psychiatric outcomes (HR 1.4, 95% CI 1.2-1.5). The risk estimates were slightly decreased when adjusted for birth year. A limitation of the study was that we had no information about Peyronie’s disease diagnoses assigned before year 1997. Conclusions: Men with Peyronie’s disease are at increased risk of being diagnosed with adverse psychiatric outcomes. Health care providers should ensure that men with Peyronie’s disease have a documented mental health status assessment.

1,3-Butadiene (BD) is abundant in combustion products such as cigarette smoke. While BD has been classified as a known human carcinogen, a long-standing question is the identity of the ultimate carcinogenic metabolite in humans. We hypothesize that 3,4-epoxybutane-1,2-diol (EBD) may play a critical role in human carcinogenesis due to its high bioavailability. We utilized a differential toxicity assay for BD metabolites and newly synthesized EBD analogs in a series of isogenic chicken cells lacking specific DNA repair proteins to address the mode of action of BD genotoxicity and infer a mode of action. Surprisingly, as with the diepoxide 1,2:3,4-diepoxybutane (DEB), the monoepoxide EBD showed remarkable toxicity to cells deficient in Fanconi anemia (FANC) genes. This observation suggests that EBD may be transformed into a bifunctional metabolite and forms interstrand cross-links. EBD and its analog with a hydroxy substituent at C1 were found to be highly toxic to FANCD2-deficient chicken and human cells. The Results suggest that EBD may be transformed to a bifunctional epoxy aldehyde, perhaps by alcohol dehydrogenase, to which the observed FANC sensitivity could be attributed. The implications of this study are very important in considering mechanisms by which EBD may cause leukemia and lymphoma in humans exposed to BD. (C) 2020 Elsevier Ltd. All rights reserved.

This study examined associations of self-regulatory behavior and cognitive functioning with substance use (SU) to inform interventions for youth with perinatal HIV infection (YPHIV) or exposure but uninfected (YPHEU). Youth aged 7-15 years (YPHIV, n = 390; YPHEU, n = 211) were followed longitudinally with cognitive testing and behavioral questionnaires including self-report of alcohol, marijuana, tobacco, and other SU. Cox proportional hazards analyses were used to examine correlates of initiating each substance for those without prior use at baseline and generalized estimating equation analyses were used to address associations of cognitive/behavioral measurements with SU prevalence for the entire sample. Lower self-reported self-regulation skills, but higher cognitive functioning abilities, were associated with initiation and prevalent use of alcohol and marijuana regardless of HIV status. Our findings suggest SU screening tools and self-regulation interventions developed for general adolescent populations should be implemented for those with PHIV, who may be at heightened risk for SU-related health consequences.

Flame-retardant PNIPAAm/sodium alginate/polyvinyl alcohol hydrogels used for fire-fighting application: Preparation and characteristic evaluations

A novel fire-preventing triple-network (TN) hydrogel was prepared and laminated on cotton fabric to improve fire-resistant performance of cellulose fabric. The TN hydrogel composed of Poly (N-isopropylacrylamide) (PNIPAAm)/sodium alginate (SA)/ Poly (vinyl alcohol) (PVA) exhibited excellent swelling ratio, swelling-deswelling behavior and antibacterial property. Results indicated that introduction of SA could improve water retention capabilities of TN hydrogels. Thermogravimetric experiments showed that the thermal stability of hydmgels was best at a SA: PVA ratio of 2:1. Furthermore, the obtained hydrogel-cotton fabric laminates displayed efficient flame retardancy. Compared to original fabric, hydrogel-fabric laminates were nearly undamaged when exposed to fire for 12 s. This result is attributed to energy absorption as water is heated and evaporates in the hydrogel. The present work provides a new concept to prepare fire-resistant polymer fabric, which may be used in fire-protective clothing to protect the skin from burn injuries.

Microneedle-assisted technology for minimally invasive medical sensing

In recent years, applications of microneedle (MN) technology in medical health sensing devices and platforms have been developed due to its advantages of minimal invasiveness, real-time, and convenience. Electrochemical biosensors and interstitial fluid (ISF) direct extraction are two types of MN based technologies applied in medical sensing. In MN based electrochemical biosensors, conducting polymers (CPs), enzymes, nanoparticles, and their composites are used to modify MN electrodes to selectively monitor glucose, lactate, alcohol, urea, amino acids, therapeutic drugs, or bio-signals recording. In MN based ISF direct extraction for further sensing, silicon, silicon oxide, and some polymers are introduced to the fabrication of hollow or hydrogel MNs. These two types of MN based technologies were employed in glucose monitoring, therapeutic drug monitoring (TDM), protein analysis, etc. This review is to present the development and application of MN based technologies on electrochemical biosensors and ISF direct extraction and also to describe some prospects and limitations on medical sensing.

Fe3+, NIR light and thermal responsive triple network composite hydrogel with multi-shape memory effect

Recently, artificial intelligence has driven the development of shape memory hydrogels (SMHs) with complicated environmental sensitive abilities. However, current SMHs possess fundamental limitations in terms of their responsive performance and mechanical properties, which severely limits their practical applications. Herein, a triple-network composite hydrogel with Fe3+, NIR light, and thermal responsive abilities is fabricated and developed as multi-SMHs, named as PDA/CMC-Fe3+/PVA hydrogel. In this hydrogel system, the interpenetrating triple network are formed by chemically-physically co-crosslinked polyvinyl alcohol (PVA) networks, and physically crosslinked carboxymethyl cellulose (CMC)-Fe3+ network. In addition, polydopamine (PDA), which is introduced into the hydrogel system by in-situ polymerization way, could not only serve as an energy converter to endow the hydrogel with NIR-based responsive ability, but also enhance its mechanical strength. Remarkably, the as-prepared PDA/CMC-Fe3+/PVA hydrogels with the optimized compositions exhibit relatively excellent mechanical properties (tensile strength = 163.48 +/- 10.42 kPa, elastic modulus = 45.42 +/- 3.96 kPa, toughness = 165.02 +/- 7.01 kJ/m(3)) due to the synergistic effect of the triple-network and PDA doping. Moreover, the composition of the hydrogel is optimized to realize a stable temporary shape and rapid recovery to the permanent shape, which is controlled by Fe3+, NIR irradiation, and thermal stimulus. The resultant hydrogels exhibit not only multi-stimulus responsive abilities, but also programmable multi-shape memory properties. The versatile shape memory properties endow potential for the materials to be used in the field of artificial intelligence.

Computational design of highly stable and soluble alcohol dehydrogenase for NADPH regeneration

Nicotinamide adenine dinucleotide phosphate (NADPH), as a well-known cofactor, is widely used in the most of enzymatic redox reactions, playing an important role in industrial catalysis. However, the absence of a comparable method for efficient NADP(+) to NADPH cofactor regeneration radically impairs efficient green chemical synthesis. Alcohol dehydrogenase (ADH) enzymes, allowing the in situ regeneration of the redox cofactor NADPH with high specific activity and easy by-product separation process, are provided with great industrial application potential and research attention. Accordingly, herein a NADP(+)-specific ADH from Clostridium beijerinckii was selected to be engineered for cofactor recycle, using an automated algorithm named Protein Repair One-stop Shop (PROSS). The mutant CbADH-6M (S24P/G182A/G196A/H222D/S250E/S254R) exhibited a favorable soluble and highly active expression with an activity of 46.3 U/mL, which was 16 times higher than the wild type (2.9 U/mL), and a more stable protein conformation with an enhanced thermal stability: Delta T-1/2(60min) = + 3.6 degrees C (temperature of 50% inactivation after incubation for 60 min). Furthermore, the activity of CbADH-6M was up-graded to 2401.8 U/mL by high cell density fermentation strategy using recombinant Escherichia coli, demonstrating its industrial potential. Finally, the superb efficiency for NADPH regeneration of the mutant enzyme was testified in the synthesis of some fine chiral aromatic alcohols coupling with another ADH from Lactobacillus kefir (LkADH).
