Plohl, Olivija published the artcileMesoporous silica nanoparticles modified with N-rich polymer as a potentially environmentally-friendly delivery system for pesticides, Quality Control of 42822-86-6, the main research area is mesoporous silica nanoparticle nitrogen polymer pesticide.

The focus of the article is on the design of environmentally-friendly nanocarriers for improved controlled pesticide release, which have low environmental toxicity and nitrogen elemental composition as the most important components of fertilizers. In this study, a novel delivery system was developed for post-loading a biopesticide to mesoporous silica nanoparticles (MeSiNPs) functionalized with N-rich derived polymer. Initially, MeSiNPs were synthesized by the template-assisted method, which yielded MeSiNPs in the nm range, together with highly ordered mesoporous channels with a pore size of 2.9 nm. Subsequently, the water-soluble branched polyethyleneimine (bPEI) was derived systematically with epoxy organosilicate, and functionalized on MeSiNPs to create a source of N-nutrients. The carefully designed novel nano-carrier was analyzed by several physicochem. and structural analyses, which confirmed the successful attachment of the derived bPEI to MeSiNPs. Further, the novel nano-synthesized system was used as a delivery for the model biopesticide citridiol. The loading efficiency of citridiol in/on MeSiNPs@bPEI was 19%, while the loading capacity of citridiol was proven to be 5 mg biopesticide/1 mg MeSiNPs@bPEI. The MeSiNPs@bPEI with loaded citridiol was investigated for kinetic release. The system showed a fast initial release behavior in the first 300 min, which was continued by slow release behavior and started to reach equilibrium after 10 days. It has been shown that the MeSiNPs@bPEI showed an excellent potential for use in agrochem. applications, not only as a nanocarrier for controlled and slow pesticide release, but may also act as a soil improver by providing Si and N as key nutrient sources.

Yang, Haihong published the artcileDegradation models, structure, rheological properties and protective effects on erythrocyte hemolysis of the polysaccharides from Ribes nigrum L, Related Products of alcohols-buliding-blocks, the main research area is Ribes nigrum polysaccharide structure rheol erythrocyte hemolysis protective effect; Blackcurrant polysaccharide; Degradation model; Erythrocyte hemolysis; Rheological properties; Structure; Ultrasonic treatment.

The polysaccharides from blackcurrant (Ribes nigrum L.) fruits were degraded by ultrasonic irradiation Results showed that viscosity-average mol. weight decreased with increasing ultrasonic time or power. The degradation was fitted to the second-order kinetics model and midpoint chain scission model. Gas chromatog. anal. demonstrated that the native polysaccharide and three degraded polysaccharides were composed of the same monosaccharides but in different ratios. Fourier transform IR and NMR spectroscopic analyses revealed the presence of α-, β-pyranose rings and the same six sugar residues in the four blackcurrant polysaccharides. Compared to the native polysaccharide, three degraded polysaccharides displayed better rheol. properties and stronger protective effects against erythrocyte hemolysis. Collectively, the results support the potential utility of blackcurrant polysaccharides as natural antioxidants.

Ribeiro, Rita published the artcileComparing the effect of Thymus spp. essential oils on Candida auris, Product Details of C10H18O, the main research area is Thymus Candida auris essential oil comparing effect.

Candida auris is an emergent yeast pathogen responsible for many invasive fungal infections due to its multidrug-resistant character and its huge transmission ability. Essential oils (EOs) obtained from several aromatic plants have been regarded as an alternative treatment upon to fungal infections. For example, Thymus spp. are known by their antifungal effect due to the presence of some volatile compounds in their EOs, such as carvacrol, thymol, linalool and gamma-terpinene. So, the main goal of this work was to compare the effect of several EOs from Thymus spp. on C. auris biofilm. The antifungal activity of Thymus vulgaris, Thymus zygis, Thymus satureioides and Thymus mastichina against planktonic cells of C. auris NCPF 8971 was assessed by agar disk diffusion method. The effect of these EOs with direct or vapor phases on preformed biofilms was evaluated by colony-forming unitsprime enumeration. Importantly it was noticed a completely different range of action between the EOs from the same genus. While T. vulgaris showed the biggest antifungal effect with a halo of 59.75 plusmn 15.75 mm, T. mastichina for the other side, presented a halo of 13.13 plusmn 1.36 mm, showing a very low activity. In addition, the direct application of T. vulgaris and T. zygis EOs demonstrated higher antifungal activity against C. auris biofilms than vapor phase application. However, T. vulgaris also showed significant action in the vapor phase mode. The chem. composition of Thymus EOs was analyzed by GC and GC-MS, and was demonstrated that they have different chem. profiles, namely in the amount of phenolic compounds, which justify the different antifungal actions.In conclusion, T. vulgaris and T. zygis oils, can be pointed out as a great contribution to the treatment of C. auris infections, being promising alternatives to conventional therapy. However, the efficiency of the EOs differs substantially between the four species of Thymus. Therefore, the selection of natural therapies should always have in account EOs composition

Abreu, Hellen published the artcilePolysaccharides from Pleurotus eryngii: Selective extraction methodologies and their modulatory effects on THP-1 macrophages, Recommanded Product: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is mannogalactan IL1B IL10 Pleurotus immunomadulatory activity macrophage; Immunostimulatory properties; Mannogalactan; Pleurotus eryngii mushroom; Polysaccharides; β-D-glucansgg.

Polysaccharides from P. eryngii mushroom were selectively extracted using low-cost technologies (water at different conditions of temperature and pressure). Mannogalactan was the main polysaccharide in cold-water extracted fraction (CWEF), while a linear (1→6)-β-D-glucan was the main polymer in hot-water extracted fraction (HWEF). Autoclave-extracted fraction (AEF) contained a mixture of at least four different α- and β-glucans. The report of linear (1→6)-β-glucan and linear (1→3)-β-glucan is a new finding for P. eryngii fruiting bodies. The immunostimulatory properties of the fractions on THP-1 macrophages were studied. All fractions at 50, 250 and 500μg/mL were not cytotoxic and produced different stimulus on NO, IL-1β and IL-10 secretion by the cells. Thus, our results showed that it is possible to concentrate different P. eryngii polysaccharides in selected fractions using a simple and low-cost procedure. Since biol. effects depends on the polysaccharide structure, this technique allows the obtainment of fractions with distinct immunomodulatory activities.

Mikkelsen, Maria Dalgaard published the artcileAncient origin of fucosylated xyloglucan in charophycean green algae, Recommanded Product: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Xyloglucan cell wall Charophycean.

The charophycean green algae (CGA or basal streptophytes) are of particular evolutionary significance because their ancestors gave rise to land plants. One outstanding feature of these algae is that their cell walls exhibit remarkable similarities to those of land plants. Xyloglucan (XyG) is a major structural component of the cell walls of most land plants and was originally thought to be absent in CGA. This study presents evidence that XyG evolved in the CGA. This is based on (a) the identification of orthologs of the genetic machinery to produce XyG, (b) the identification of XyG in a range of CGA and, (c) the structural elucidation of XyG, including uronic acid-containing XyG, in selected CGA. Most notably, XyG fucosylation, a feature considered as a late evolutionary elaboration of the basic XyG structure and orthologs to the corresponding biosynthetic enzymes are shown to be present in Mesotaenium caldariorum.

Jiang, Yuan-yuan published the artcileExtraction and antioxidant activities of polysaccharides from roots of Arctium lappa L., Synthetic Route of 59-23-4, the main research area is Arctium root polysaccharide ultrasonic assisted extraction antioxidant; Antioxidant activities; Arctium lappa L.; Polysaccharides; Ultrasonic-assisted extraction.

Polysaccharides were extracted from the roots of Arctium lappa L. (ALPs) using response surface methodol. with ultrasonication. A central composition design was used to optimize extraction parameters by maximizing the polysaccharide extraction yield. The modified optimal conditions were as follows: water to raw material ratio of 31 mL/g, ultrasonic power of 158 W, extraction time of 83 min, and extraction temperature of 50°C. Furthermore, fractions of ALP40-1, ALP60-1, and ALP80-1 were obtained for chem. and antioxidant activity analyses after purification Results indicated that the three fractions had a mol. weight of 218, 178, and 60 kDa, resp., and were composed of mannose, glucose, fructose, and galactose. ALP60-1 exhibited strong scavenging activities on 1,1-diphenyl-2-picryhydrazyl, hydroxyl, and superoxide radicals. These results demonstrate that ultrasonic-assisted extraction is a very effective method for extracting ALPs, and ALP60-1 is a potential novel natural antioxidant. However, further structure elucidation and in vivo experiments are required.

Gonka, Elzbieta published the artcileExpanded Hexapyrrolohexaazacoronenes. Near-Infrared Absorbing Chromophores with Interrupted Peripheral Conjugation, Category: alcohols-buliding-blocks, the main research area is expanded hexapyrrolohexaazacoronene near IR absorbing chromophore interrupted peripheral conjugation.

A family of azacoronenes containing up to two saturated bridges at the periphery was synthesized from substituted hexapyrrolylbenzenes using a two-step condensation-aromatization procedure. The introduction of peripheral bridges provides access to nonplanar, sterically crowded systems that display complex reactivity patterns, involving stereospecific aromatization of bridges and nucleophile additions Despite the interrupted conjugation on the periphery, the new azacoronenes have easily accessible higher oxidation levels, and a quadruply charged species was chem. generated by reaction with SbCl5. These oxidized species show extensive π-electron conjugation and are efficient UV-vis-NIR absorbers, active up to ca. 2400 nm. Interruption of peripheral conjugation is shown to induce a tendency toward biradicaloid electron configurations in doubly oxidized species.

He, Shudong published the artcilePotential effects of rapeseed peptide Maillard reaction products on aging-related disorder attenuation and gut microbiota modulation in D-galactose induced aging mice, Synthetic Route of 59-23-4, the main research area is galactose aging disorder gut microbiota rapeseed peptide MRP.

As a good flavor enhancer, rapeseed peptide Maillard reaction products (MRPs) were developed, and the effects of MRPs on D-galactose induced aging Kunming mice were investigated for 6 wk with low (200 mg kg-1 day-1), medium (400 mg kg-1 day-1) and high (800 mg kg-1 day-1) doses. Compared with the natural aging group and D-galactose induced aging mice, the mice with MRP administration showed increases in body weight gain, food intake, organ indexes, feces color and urine fluorescence intensity. MRP intake significantly decreased the MDA content and elevated the activities of CAT, SOD and GSH-Px, and T-AOC in the serum and tissues of the liver, kidney and brain. Addnl., AChE activity was decreased in the brain, while Na+-K+ ATPase and Ca2+-Mg2+ ATPase activity increased in a dose-dependent manner, and decreasing levels of IL-1β, IL-6 and TNF-α were observed in the liver and kidney. Histopathol. anal. suggested an attenuation of inflammatory cell infiltration in the liver and kidney without cell necrosis. High-throughput sequencing results revealed that the ratio of Firmicutes to Bacteroidetes increased in MRP groups, and the pathogenic bacteria were significantly inhibited, while some beneficial bacteria were significantly increased in the intestine. Overall, our results indicated that MRP consumption might have potential beneficial effects on postponing the aging process via reducing the oxidative stress and gut microflora modulation.

Fu, Yousi published the artcileAn in vitro fermentation study on the effects of Dendrobium officinale polysaccharides on human intestinal microbiota from fecal microbiota transplantation donors, Category: alcohols-buliding-blocks, the main research area is polysaccharide Dendrobium fermentation intestinal microbiota transplantation.

The current study investigated the effects of Dendrobium officinale polysaccharides (DOP) on human intestinal microbiota composition and metabolism via in vitro fermentation Following 48 h of fermentation, 63.88% ± 2.40% of the total carbohydrate in the DOP was consumed and pH decreased from 6.95 to 4.70. Meanwhile, the total short chain fatty acid (SCFA) productions significantly increased, with the major SCFA being acetic, propionic and butyric acids. 16S rRNA anal. revealed several differences in the intestinal microbiota community structure between the DOP-treatment culture and control, DOP increased the population of Firmicutes and Bacteroidetes and decreased the abundance of Proteobacteria. PICRUSt functional profile prediction revealed that DOP increased the abundance of genes in amino acid and fatty acid metabolic pathways. The results of metabolites determination also showed higher amino acids and fatty acids metabolites. These results suggest that polysaccharides from Dendrobium officinale have prebiotic potential and may improve gastrointestinal health.

Miro Specos, Maria M. published the artcileApplication of microencapsulated biopesticides to improve repellent finishing of cotton fabrics, Computed Properties of 42822-86-6, the main research area is microencapsulated biopesticide repellent finishing cotton fabric.

Insect repellent textiles are currently being investigated as a complementary tool to control disease vectors, such as mosquitoes. The application of microencapsulated biopesticides to textiles is a promising low-toxicity alternative to other control methods, as microcapsules may prolong the release of the repellent agent. In this work, microcapsules containing two biopesticides, namely citronella essential oil and citriodiol were prepared and applied to cotton textiles using a variety of techniques. The aim of this work was to evaluate these functional textiles to select the most efficient, durable systems. Citriodiol-treated cotton presented a prolonged durability, and 100% repellency could be achieved for more than 30 days after padding onto cotton fabrics. It has to be pointed out that all these repellent textiles have been obtained by scalable, low-cost methods which would require no addnl. investment for textile finishing industries.
