Gao, Xiong published the artcileStructural characterization and immunomodulatory activity of a water-soluble polysaccharide from Ganoderma leucocontextum fruiting bodies, Recommanded Product: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is water soluble polysaccharide Ganoderma fruiting body; Ganoderma leucocontextum; Immunostimulatory activity; Polysaccharide; Structure; Toll-like receptor 2.

Ganoderma leucocontextum is a new species of Ganoderma discovered in 2014. Up to now, the structural characteristics and immunoregulatory activity of its polysaccharides remain virtually unknown. In this study, a water-soluble polysaccharide termed, GLP-3, was purified from G. leucocontextum by ultrafiltration and column chromatog. The results revealed that GLP-3 mainly consisted of glucose (92.7%) and its weight average mol. weight was 159.7 kDa. The structural anal. indicated that the backbone of GLP-3 was →4-α-D-Glcp-(1→4,6)-β-D-Glcp-1→ with a β-Glcp-1→ branch. Atomic force microscopy and Congo red experiments revealed that GLP-3 might possess a globular structure with triple-helix conformation in water. Moreover, GLP-3 was recognized by toll-like receptor 2 (TLR2) and exerted immunomodulatory effects via activating mitogen-activated protein kinases (MAPKs), phosphatidylinositol-3-kinase (PI3K)/Akt and nuclear factor-κB (NF-κB) signaling pathways in RAW 264.7 macrophages. Collectively, these results suggested that GLP-3 could be developed as a potential functional food ingredient for immunomodulation.

Mestre, Maria Victoria published the artcileImpact on Sensory and Aromatic Profile of Low Ethanol Malbec Wines Fermented by Sequential Culture of Hanseniaspora uvarum and Saccharomyces cerevisiae Native Yeasts, Formula: C4H10OS, the main research area is Hanseniaspora Saccharomyces ethanol wine sensory profile.

It is well known that high ethanol levels in wines adversely affect the perception of new wine consumers. Moreover, numerous issues, such as civil restrictions, health risk and trade barriers, are associated with high ethanol concentrations Several strategies have been proposed to produce wines with lower alc. content, one simple and inexpensive approach being the use of new wine native yeasts with less efficiency in sugar to ethanol conversion. Nevertheless, it is also necessary that these yeasts do not impair the quality of wine. In this work, we tested the effect of sequential culture between Hanseniaspora uvarum BHu9 and Saccharomyces cerevisiae BSc114 on ethanol production Then, the wines produced were analyzed by GC-MS and tested by a sensorial panel. Co-culture had a pos. impact on ethanol reduction and sensory profile when compared to the S. cerevisiae monoculture. Wines with lower alc. content were related to fruity aroma; moreover, color intensity was associated The wines obtained with S. cerevisiae BSc114 in pure conditions were described by parameters linked with high ethanol levels, such as hotness and astringency. Moreover, floral profile was related to this treatment. Based on these findings, this work provides a contribution to answer the current consumers’ preferences and addresses the main challenges faced by the enol. industry.

Zhang, Bo published the artcileEndogenous calcium attenuates the immunomodulatory activity of a polysaccharide from Lycium barbarum L. leaves by altering the global molecular conformation, Computed Properties of 59-23-4, the main research area is Lycium leaf macrophage calcium heteropolysaccharide immunomodulation; Conformation; FTIR; Goji; Macrophage; Mannose; Uronic acid.

A heteropolysaccharide, LP5, was purified from Lycium barbarum L. leaves. It was identified as a calcium-rich polysaccharide (8.6 mg calcium/g) with a mol. weight of 2.50 × 105 Da. The polysaccharide was composed of six kinds of monosaccharides, of which mannose and xylose are the main components. And it contains 16.37% glucuronic acid. Studies on RAW264.7 cells demonstrated that this polysaccharide exhibited potent immunomodulatory activity, including an increase in phagocytic activity, as well as the release of both nitric oxide and cytokines. However, after the depletion of calcium, the polysaccharide exhibited greater immunomodulatory activity (p < 0.05). Further conformation anal. confirmed that the polysaccharide changed from a compact spherical conformation to a random coil structure in aqueous solution after the depletion of calcium, which resulted in increased immunomodulatory activity by LP5.

Park, Hye-Ryung published the artcileSignaling pathway and structural features of macrophage-activating pectic polysaccharide from Korean citrus, Cheongkyool peels, Name: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Cheongkyool peel macrophage pectic polysaccharide signaling; Cheongkyool; MAPK; NF-κB; Polysaccharide; Rhamnogalacturonan-I.

To characterize the immuno-stimulating ingredient from the Korean citrus, Cheongkyool, a crude polysaccharide (CCE-0) was isolated from the pectinase digests of Cheongkyool peels, from which the complex polysaccharide CCE-I was purified to homogeneity by gel filtration. CCE-I highly enhanced the production of IL-6, TNF-α, and NO in RAW 264.7 cell lines. It augmented the mRNA expression of IL-6, TNF-α, and iNOS in a dose-dependent manner. Moreover, CCE-I dose-dependently induced phosphorylation of MAPKs and NF-κB related proteins and led to the nuclear translocation of p65. The effect of CCE-I on NO and IL-6 production was suppressed by treatment with specific antibodies for TLR2, TLR4, and scavenger receptors. Conversely, the primary structure of CCE-I that exhibited potent immunostimulatory activity was characterized by sugar composition, linkage anal., and oligosaccharide anal. after β-elimination. The results suggested that CCE-I may be a rhamnogalacturonan-I type, highly branched polysaccharide with short arabinan and galactan side chains.

Cheng, Gang published the artcilePotent inhibition of tumour cell proliferation and immunoregulatory function by mitochondria-targeted atovaquone, Recommanded Product: (S)-2-hydroxysuccinic acid, the main research area is cancer cell mitochondrial complex III atovaquone antiproliferative triphenylphosphonium.

Abstract: The FDA-approved prophylactic antimalarial drug atovaquone (ATO) recently was repurposed as an antitumor drug. Studies show that ATO exerts a profound antiproliferative effect in several cancer cells, including breast, ovarian, and glioma. Analogous to the mechanism of action proposed in parasites, ATO inhibits mitochondrial complex III and cell respiration. To enhance the chemotherapeutic efficacy and oxidative phosphorylation inhibition, we developed a mitochondria-targeted triphenylphosphonium-conjugated ATO with varying alkyl side chains (Mito4-ATO, Mito10-ATO, Mito12-ATO, and Mito16-ATO). Results show, for the first time, that triphenylphosphonium-conjugated ATO potently enhanced the antiproliferative effect of ATO in cancer cells and, depending upon the alkyl chain length, the mol. target of inhibition changes from mitochondrial complex III to complex I. Mito4-ATO and Mito10-ATO inhibit both pyruvate/malate-dependent complex I and duroquinol-dependent complex III-induced oxygen consumption whereas Mito12-ATO and Mito16-ATO inhibit only complex I-induced oxygen consumption. Mitochondrial target shifting may have immunoregulatory implications.

Spera, Iolanda published the artcileThe J2-Immortalized Murine Macrophage Cell Line Displays Phenotypical and Metabolic Features of Primary BMDMs in Their M1 and M2 Polarization State, COA of Formula: C4H6O5, the main research area is inflammation BMDM macrophage polarization phenotype metabolism; cell line; immortalized macrophages; immune model; inflammation; macrophage; metabolism.

Macrophages are immune cells that are important for the development of the defensive front line of the innate immune system. Following signal recognition, macrophages undergo activation toward specific functional states, consisting not only in the acquisition of specific features but also of peculiar metabolic programs associated with each function. For these reasons, macrophages are often isolated from mice to perform cellular assays to study the mechanisms mediating immune cell activation. This requires expensive and time-consuming breeding and housing of mice strains. To overcome this issue, we analyzed an inhouse J2-generated immortalized macrophage cell line from BMDMs, both from a functional and metabolic point of view. By assaying the intracellular and extracellular metabolism coupled with the phenotypic features of immortalized vs. primary BMDMs, we concluded that classically and alternatively immortalized macrophages display similar phenotypical, metabolic and functional features compared to primary cells polarized in the same way. Our study validates the use of this immortalized cell line as a suitable model with which to evaluate in vitro how perturbations can influence the phenotypical and functional features of murine macrophages.

Ozyagci, Bensu published the artcileEsterification of 1-Octanol on Clinoptilolite-Supported TiO2 Catalysts, Safety of n-Octanol, the main research area is octanol clinoptilolite supported titanium oxide catalyst esterification.

In this study, a natural type of zeolite, Clinoptilolite (CLI), is used as a support for TiO2. First, TiO2-supported heterogeneous catalysts originated from the high temperature calcination of TiCl4 groups, which were thermally immobilized on clinoptilolite, were obtained. Powder-XRD and EDX analyzes showed that the oxide form of Ti-immobilized on dealuminated clinoptilolite were formed in the anatase phase, and the zeolite structure was preserved. As seen in TGA/DTA analyzes, this catalyst could be efficient and have high stability for many reactions. Second, the esterification reaction of 1-octanol with acetic acid is used as a reference reaction for this catalyst.

Priestley, C. M. published the artcileLethality of essential oil constituents towards the human louse, Pediculus humanus, and its eggs, Recommanded Product: 2-(2-Hydroxypropan-2-yl)-5-methylcyclohexanol, the main research area is insecticide ovicide essential oil Pediculus humanus.

Essential oils have been widely used in traditional medicine for the eradication of lice, including head lice, but due to the variability of their constitution the effects may not be reproducible. In an attempt to assess the contribution of their component monoterpenoids, a range of common individual compounds were tested in in vitro toxicity model against both human lice (Pediculus humanus, an accepted model of head lice lethality) and their eggs, at different concentrations No detailed study into the relative potencies of their constituent terpenoids has so far been published. Adult lice were observed for lack of response to stimuli over 3 h and the LT50 calculated, and the percentage of eggs failing to hatch was used to generate ovicidal activity data. A ranking was compiled for adult lice and partially for eggs, enabling structure-activity relationships to be assessed for lethality to both, and showed that, for activity in both life-cycle stages, different structural criteria were required. (+)-Terpinen-4-ol was the most effective compound against adult lice, followed by other mono-oxygenated monocyclic compounds, whereas nerolidol was particularly lethal to eggs, but ineffective against adult lice.
