Dutta, Kingshuk published the artcileSymbiotic Self-Assembly Strategy toward Lipid-Encased Cross-Linked Polymer Nanoparticles for Efficient Gene Silencing, Quality Control of 142-90-5, the main research area is self assembly lipid crosslinking polymer nanoparticle gene silencing; DOPE; MDR1; PLK1; eGFP; gene silencing; noncationic delivery agent; random copolymer; siRNA delivery; symbiotic self-assembly; zwitterionic lipids.

A novel “”symbiotic self-assembly”” strategy that integrates the advantages of biocompatible lipids with a structurally robust polymer to efficiently encapsulate and deliver siRNAs is reported. The assembly process is considered to be symbiotic because none of the assembling components are capable of self-assembly but can form well-defined nanostructures in the presence of others. The conditions of the self-assembly process are simple but have been chosen such that it offers the ability to arrive at a system that is noncationic for mitigating carrier-based cytotoxicity, efficiently encapsulate siRNA to minimize cargo loss, be effectively camouflaged to protect the siRNA from nuclease degradation, and efficiently escape the endosome to cause gene knockdown. The lipid-siRNA-polymer (L-siP) nanoassembly formation and its disassembly in the presence of an intracellular trigger have been extensively characterized exptl. and through computational modeling. The complexes have been evaluated for the delivery of four different siRNA mols. in six different cell lines, where an efficient gene knockdown is demonstrated. The reported generalized strategy has the potential to make an impact on the development of a safe and effective delivery agent for RNAi-mediated gene therapy that holds the promise of targeting several hard-to-cure diseases.

Hayashi, Naoki published the artcileSolubility of thermostable alkyl phosphate ester copper complexes in poly(alkyl methacrylate) for near-infrared-absorbing dyes, HPLC of Formula: 142-90-5, the main research area is solubility alkylphosphate ester copper polyalkyl methacrylate IR absorbing dye.

To realize thermoplastic near-IR-absorbing resin materials with weak absorbance in the visible region, the solubility of thermostable alkyl phosphate ester copper complexes in poly(alkyl methacrylate) was investigated for their use as near-IR-absorbing dyes. C4-C12 alkyl phosphate ester copper complexes were synthesized and mixed with Bu methacrylate, 2-ethylhexyl methacrylate, and lauryl methacrylate at 0.10 mol/g copper ion in the monomer solution The obtained solutions were polymerized to prepare 3 mm resin plates, and the plate transparency was evaluated by a haze meter. 2-Ethylhexyl methacrylate solutions of the 2-ethylhexyl phosphate copper complex and the isodecyl phosphate copper complex maintained their transparency even after polymerization, so these two copper complexes show good solubility in poly(2-ethylhexyl methacrylate). Both of the resin plates have >80% visible light transmittance and <50% solar direct transmittance. Thus, these resin materials are suitable as window materials that require heat-shielding properties and transparency.

Zhang, Yunchong published the artcileHighly Stable and Nonflammable Hydrated Salt-Paraffin Shape-Memory Gels for Sustainable Building Technology, Computed Properties of 142-90-5, the main research area is stable nonflammable hydrated salt paraffin memory gel.

Hydrated salts (salt hydrates) are highly promising low-temperature phase change materials (PCMs) due to their high cohesive energy d. and low cost. However, they exhibit phase separation, liquid leakage, and inherent supercooling, which hinder their applications in sustainable building technol. Here, we describe the design of a highly stable emulsion gel system (EmulGels) that exhibits nonflammable and shape-memory characteristics. Oleophilic paraffin and hydrophilic hydrated salts, both of which are excellent PCMs typically existing in sep. phases, are combined harmoniously in a gel by a templating water-in-oil Pickering emulsion. Latent heat values of the prepared EmulGels were up to 213.2 J/g (eicosane/disodium hydrogen phosphate dodecahydrate = 1:3). No leakage of eicosane was noticed after heating the EmulGels at 60 °C for 30 min, and the latent heat value remained almost unchanged following 500 thermal cycles. The EmulGel was specifically designed to enable dual-phase crosslinking, which effectively enhanced its shape stability, slowed down loss of water of crystallization in hydrated salts, and decreased the degree of supercooling. Nonflammable characteristic typically found in hydrated salts was also exhibited by the EmulGel, in combination with good mech. properties. The materials characteristics make EmulGels ideal candidates to serve as building construction interlayers for effective thermal building management.

Kufel, Wesley D. published the artcileSuccessful treatment with secnidazole for trichomoniasis in the setting of metronidazole hypersensitivity, Recommanded Product: 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate, the main research area is secnidazole metronidazole trichomoniasis nitazoxanide Trichomonas vaginalis; Secnidazole; Trichomonas vaginalis; metronidazole; nitazoxanide; trichomoniasis.

Limited effective treatment options currently exist for trichomoniasis management among patients with metronidazole hypersensitivity. We report a patient with a documented history of metronidazole hypersensitivity who initially was treated with nitazoxanide but demonstrated clin. and microbiol. failure. Secnidazole was subsequently used for treatment, which resulted in clin. and microbiol. cure without observation of cross-reactivity. Secnidazole may represent a potential treatment option for trichomoniasis in patients with metronidazole hypersensitivity after consultation with an infectious disease specialist.

Soelter, Jan published the artcileComputational exploration of molecular receptive fields in the olfactory bulb reveals a glomerulus-centric chemical map, COA of Formula: C9H18O2, the main research area is dorsal olfactory bulb glomerulus centric chem map computational exploration.

Progress in olfactory research is currently hampered by incomplete knowledge about chem. receptive ranges of primary receptors. Moreover, the chem. logic underlying the arrangement of computational units in the olfactory bulb has still not been resolved. We undertook a large-scale approach at characterizing mol. receptive ranges (MRRs) of glomeruli in the dorsal olfactory bulb (dOB) innervated by the MOR18-2 olfactory receptor, also known as Olfr78, with human ortholog OR51E2. Guided by an iterative approach that combined biol. screening and machine learning, we selected 214 odorants to characterize the response of MOR18-2 and its neighboring glomeruli. We found that a combination of conventional physico-chem. and vibrational mol. descriptors performed best in predicting glomerular responses using nonlinear Support-Vector Regression. We also discovered several previously unknown odorants activating MOR18-2 glomeruli, and obtained detailed MRRs of MOR18-2 glomeruli and their neighbors. Our results confirm earlier findings that demonstrated tunotopy, i.e., glomeruli with similar tuning curves tend to be located in spatial proximity in the dOB. In addition, our results indicate chemotopy, i.e., a preference for glomeruli with similar physico-chem. MRR descriptions being located in spatial proximity. Together, these findings suggest the existence of a partial chem. map underlying glomerular arrangement in the dOB. Our methodol. that combines machine learning and physiol. measurements lights the way towards future high-throughput studies to deorphanise and characterize structure-activity relationships in olfaction.

Chen, Jia published the artcileEster-producing mechanism of ethanol O-acyltransferase EHT1 gene in Pichia pastoris from Shanxi aged vinegar, SDS of cas: 111-11-5, the main research area is Pichia EHT1 esterase volatile fatty acid vinegar.

The ethanol O-acyltransferase EHT1 is an important element of key signaling pathways and is widely expressed in yeast strains. In this study, we investigated the expression of EHT1 in the overexpression lines or knockout system of Pichia pastoris using qRT-PCR and western blotting.The amount of total protein was determined using the Bradford method; the esterase activity was determined using p-nitrophenyl acetate as a substrate, and the production of volatile fatty acids in wild-type, knockout, and over-expression systems was detected using SPME GC-MS. The esterase activity of EHT1-knockout P. pastoris was significantly lower than that in wild type (P<0.01), and the activities of esterase in three EHT1-overexpressing strains-OE-1, OE-2, and OE-3-were significantly higher than those in wild type (P<0.01). In the EHT1-knockout strain products, the contents of nine volatile fatty acids were significantly lower than those in wild type (P<0.01), and the relative percentages of three fatty acids, Me nonanoate, Me decanoate, and Et caprate, were significantly lower than those in the other six species in the wild-type and knockout groups (P<0.05). The nine volatile fatty acids in the fermentation products of the overexpressed EHT1 gene were significantly higher than those in the wild-type group (P<0.01). The relative percentages of the three fatty acid esters,methyl nonanoate,methyl caprate, and Et caprate, were significantly higher than those in the other six species (P<0.05). EHT1 plays an important regulatory role in esterase activity and the production of medium-chain volatile fatty acids.

Zhang, Boqin published the artcileSynergistic effect enhances 2-phenylethyl acetate production in the mixed fermentation of Hanseniaspora vineae and Saccharomyces cerevisiae, Related Products of esters-buliding-blocks, the main research area is phenylethyl acetate fermentation Hanseniaspora vineae Saccharomyces cerevisiae.

2-Phenylethyl acetate (2-PEA) is a desired aroma compound in wine due to its honey- and flowery-like characteristics. The effects of adding L-phenylalanine (Phe) during 2-PEA production were investigated in the co-fermentation of Hanseniaspora vineae (HV6) and Saccharomyces cerevisiae BDX. BDX and HV6 strains overproduced 2-phenylethyl alc. (2-PE) and 2-PEA, resp. The co-fermentation of BDX and HV6 achieved a 14.9 fold increase in 2-PEA odor activity value (OAV) but a 42.0% reduction of 2-PE OAV compared to BDX fermentation; the 2-PEA concentration was significantly higher than the sum of BDX and HV6 pure fermentations This suggests that BDX and HV6 have synergistic effects on 2-PEA formation in mixed culture. Adding 151.6 mg/L Phe enhanced the OAV of 2-PEA by 52.8% compared to the control. The combination of Phe addition with the co-fermentation of S. cerevisiae and H. vineae is a potential way to increase 2-PEA production and improve wine aromatic quality.

Korenika, Ana-Marija Jagatic published the artcileInfluence of L. thermotolerans and S. cerevisiae commercial yeast sequential inoculation on aroma composition of red wines (Cv Trnjak, Babic, Blatina and Frankovka), COA of Formula: C6H12O3, the main research area is cerevisiae yeast aroma red wines.

Even though Saccharomyces cerevisiae starter cultures are still largely used nowadays, the non-Saccharomyces contribution is re-evaluated, showing pos. enol. characteristics. Among them, Lachancea thermotolerans is one of the key yeast species that are desired for their contribution to wine sensory characteristics. The main goal of this work was to explore the impact of L. thermotolerans com. yeast strain used in sequential inoculation with S. cerevisiae com. yeast on the main enol. parameters and volatile aroma profile of Trnjak, BabiC, Blatina, and Frankovka red wines and compare it with wines produced by the use of S. cerevisiae com. yeast strain. In all sequential fermented wines, lactic acid concentrations were significantly higher, ranging from 0.20 mg/L in Trnjak up to 0.92 mg/L in Frankovka wines, while reducing alc. levels from 0.1% volume/volume in Trnjak up to 0.9% volume/volume in Frankovka wines. Among volatile compounds, a significant increase of Et lactate and iso-Bu acetate, geraniol, and geranyl acetate was detected in all wines made by use of L. thermotolerans. In BabiC wines, the strongest influence of sequential fermentation was connected with higher total terpenes and total ester concentrations, while Trnjak sequentially fermented wines stood up with higher total aldehyde, volatile phenol, and total lactone concentrations Control wines, regardless of variety, stood up with higher concentrations of total higher alcs., especially isoamyl alc. The present work contributed to a better understanding of the fermentation possibilities of selected non-Saccharomyces strains in the overall red wine quality modeling.

Russo, Pasquale published the artcileEffect of mixed fermentations with Starmerella bacillaris and Saccharomyces cerevisiae on management of malolactic fermentation, Application of Methyl octanoate, the main research area is Starmerella Saccharomyces malolactic mixed fermentation red wine; Lactobacillus plantarum; Malolactic fermentation; Mixed fermentation; Non-Saccharomyces; Oenococcus oeni; Starmerella bacillaris; Wine.

This work aims to improve the management of the malolactic fermentation (MLF) in red wines by elucidating the interactions between Starmerella bacillaris and Saccharomyces cerevisiae in mixed fermentations and malolactic bacteria. Two Starm. bacillaris strains were individually used in mixed fermentations with a com. S. cerevisiae. MLF was performed using two autochthonous Lactobacillus plantarum and one com. Oenococcus oeni inoculated following a simultaneous (together with S. cerevisiae) or sequential (at the end of alc. fermentation) approach. The impact of yeast inoculation on the progress of MLF was investigated by monitoring the viable microbial populations and the evolution of the main oenol. parameters, as well as the volatile organic composition of the wines obtained in mixed and pure micro-scale wine making trials. Our results indicated that MLF was stimulated, inhibited, or unaffected in mixed fermentations depending on the strains and on the regime of inoculation. O. oeni was able to perform MLF under all exptl. conditions, and it showed a minimal impact on the volatile organic compounds of the wine. L. plantarum was unable to perform MLF in sequential inoculation assays, and strain-depending interactions with Starm. bacillaris were indicated as factor affecting the outcome of MLF. Moreover, uncompleted MLF were related to a lower aromatic complexity of the wines. Our evidences indicate that tailored studies are needed to define the appropriate management of non-Saccharomyces and malolactic starter cultures in order to optimize some technol. parameters (i.e. reduction of vinification time) and to improve qual. features (i.e. primary and secondary metabolites production) of red wines.
