An integrated microfluidics for assessing the anti-aging effect of caffeic acid phenethylester in Caenorhabditis elegans

Aging is a fundamental and fascinating process. Anti-aging research tried to find the mysteries about the human lifespan. To investigate the longevity-extending role of caffeic acid phenethylester (CAPE) and reveal the possible regulation mechanism, the long-term cultivation under well-defined environments, real-time monitoring, and live imaging is highly desired. In this paper, a well-designed microfluidic device was proposed to analyze the anti-aging effect of CAPE in Caenorhabditis elegans. With the combined use of multiple functional units, including micro-pillar, worm responder, a branching network of distribution channels, and microchambers, the longitudinal measurements of the exact number of worms throughout the whole lifespans is possible. Meanwhile, the brief cooling function of temperature-controllable system can achieve temporary and repeated immobilization of nematodes for fluorescence imaging. Our research data showed that CAPE can increase the survival of worms under normal and stress condition, including heat stress and paraquat-induced oxidative stress. The further studies revealed the anti-aging mechanism of CAPE. This proposed strategy and device would be a useful platform to facilitate future anti-aging studies and the finding of new lead compounds.

Metabolomics and chemophenetics support the new taxonomy circumscription of two South America genera (Barnadesioideae, Asteraceae)

Dasyphyllum Kunth is the most diverse genus of the South American subfamily Barnadesioideae (Asteraceae), comprising 31 species most of which are distributed along the Brazilian Atlantic Forest, Cerrado and Caatinga domains. The genus has traditionally been divided into two subgenera, namely Archidasyphyllum and Dasyphyllum. However, recent phylogenetic, morphological, and biogeographical evidence led to a new circumscription of Dasyphyllum by elevating the subgenus Archidasyphyllum to the generic rank. The present work aimed to explore a chemophenetic characterization of Dasyphyllum for further supporting its new circumscription by a metabolomic approach using liquid chromatography coupled to high resolution mass spectrometry and multivariate statistical analyses. A total of 44 mass features were identified based on their UV spectra, high resolution MS data and MS2 fragmentation patterns as well as comparisons with standard compounds. Dasyphyllum samples exhibited a diversity of phenylpropanoids: 3-O-caffeoylquinic acid, 4-O-caffeoylquinic acid, 5-O-caffeoylquinic acid, 5-O-feruloylquinic acid, 5-O-caffeoylshikimic acid, 1,3-O-dicaffeoylquinic acid, 3,4-O-dicaffeoylquinic acid, 3,5-O-dicaffeoylquinic acid and 4,5-O-dicaffeoylquinic acid. On the other hand, Archidasyphyllum displayed the 2-O-caffeoyltartaric acid, 2,3-O-dicaffeoyltartaric acid and caffeoyl-feruloyltartaric acid as distinctive constituents. The occurrence of tartaric acid ester derivatives in Archidasyphyllum and its absence in Dasyphyllum may constitute a diagnostic chemical characteristic for further supporting the segregation of Archidasyphyllum from Dasyphyllum. The occurrence of phenylpropanoids in Archidasyphyllum and Dasyphyllum is here reported for the first time.

Simultaneous Dyeing and Finishing of Cotton Fabric in Presence of Starch Nanoparticles as Reinforcement Agent Using Citric Acid Based Finishing Formulation

To augment high performance, coloration and functional finishing onto cotton fabrics; novel approach for simultaneous dyeing and finishing in addition to reinforcement effect were applied by conventional pad-dry-cure method in one step. This was done to explore the potential of reduction in energy consumption and production time as well as dyes and chemicals. For this purpose, our previously prepared starch nanoparticles (SNPs) as a reinforcement biopolymer were incorporated in cross-linking formulation of cotton fabrics embracing different concentrations of citric acid and cationic dyes, i.e., Methylene Blue and Crystal Violet in presence of sodium hypophosphite as a proficient catalyst at 150(0)C for 2 minutes. Evaluation of the treated fabric performance with respect to color strength (K/S), fastness properties to light, rubbing and perspiration, add on %, dry wrinkle recovery angles, tensile strength, fabric stiffness, antibacterial effect and ultraviolet protection factor were appraised. It is seen from the obtained results that; the simultaneously dyed and finished fabric in presence of SNPs showed higher color strength, dry wrinkle recovery angle, tensile strength, fabric stiffness, antibacterial and UPF functionalities in addition to considerable light, rubbing and perspiration fastness in comparison with untreated fabric. Besides, FTIR spectra exhibited the chemical structure of treated fabrics with respect to the presence of the ester crosslinking and functional groups of cationic dyes in questions in comparison with untreated fabric. The durability of the imparted functional properties was confirmed also by washing test.

Production of methyl esters from waste cooking oil and chicken fat oil via simultaneous esterification and transesterification using acid catalyst

Low cost and environment friendly sulfonated carbon catalyst was prepared from glycerol and concentrated sulfuric acid via in situ carbonization and sulfonation. The physico-chemical properties of catalyst were determined using various techniques. The textural properties of glycerol derived sulfonated carbon catalyst (SCG) revealed amorphous structure with low surface area and pore volume. The total acid density of catalyst is found to be 35117.14 mu mol/g. SCG catalyst showed remarkable catalytic performances for simultaneous esterification and transesterification using waste cooking oil (WCO) and chicken fat oil (CFO). By using WCO, the highest FAME yield achieved was 92.3% at an optimum conditions of 5 wt% catalyst loading with 22:1 methanol to WCO molar ratio and 100 degrees C reaction temperature for 3 h. The SCG catalyst also maintained FAME yield >90% for two consecutive cycle for reusability. Meanwhile, using CFO, the highest FAME yield obtained was 90.8% at an optimised condition of 5 wt% catalyst loading with 18:1 methanol to CFO molar ratio and 70 degrees C reaction temperature for 1 h. The quality assessment of WCO methyl ester met both international standards (EN14214 and ASTM D675). The amount of sulfur in biodiesel is lower than the maximum limit of ASTM D6751.

Partially acetylated cellulose nanofibrils from Agave tequilana bagasse and Pickering stabilization

Partially acetylated cellulose nanofibrils were obtained from the major residual stream associated with tequila production. The morphology and high cellulose content of the bagasse of Agave tequilana greatly facilitated deconstruction of such underutilized biomass. Mild chemical acetylation of the starting material afforded cellulose nanofibrils bearing surface ester groups, making the system less hydrophilic and plasticized. The acetylated nanofiber were characterized for morphology (atomic force microscopy), electrostatic charge (electrophoretic mobility), degree of substitution (DS) (titration) and main chemical features (infrared spectroscopy). Aqueous suspensions of the partially acetylated nanofibers (0.5% concentration) were mixed with a non-polar organic solvent (toluene) to obtain emulsions that were stable for at least 43 days. Cellulose nanofibrils of given DSs (different wettability) formed emulsions with different droplet size, thereby producing emulsion with different properties and stability. The cellulose nanofibrils with smaller sizes and higher contact angle (81 degrees) generated small droplets (10-60 mu m) while the cellulose nanofibrils with larger sizes and smaller water contact angle (40 degrees) generated larger droplets (20-80 mu m). Agave Bagasse CNF offers a great potential as Pickering emulsion stabilizers, which can be considered in the food, cosmetic and pharmaceutical fields.

Depletion of SNRNP200 inhibits the osteo-/dentinogenic differentiation and cell proliferation potential of stem cells from the apical papilla

Background: Tissue regeneration mediated by mesenchymal stem cells (MSCs) is deemed a desirable way to repair teeth and craniomaxillofacial tissue defects. Nevertheless, the molecular mechanisms about cell proliferation and committed differentiation of MSCs remain obscure. Previous researches have proved that lysine demethylase 2A (KDM2A) performed significant function in the regulation of MSC proliferation and differentiation. SNRNP200, as a co-binding factor of KDM2A, its potential effect in regulating MSCs’ function is still unclear. Therefore, stem cells from the apical papilla (SCAPs) were used to investigate the function of SNRNP200 in this research. Methods: The alkaline phosphatase (ALP) activity assay, Alizarin Red staining, and osteogenesis-related gene expressions were used to examine osteo-/dentinogenic differentiation potential. Carboxyfluorescein diacetate, succinimidyl ester (CFSE) and cell cycle analysis were applied to detect the cell proliferation. Western blot analysis was used to evaluate the expressions of cell cycle-related proteins. Results: Depletion of SNRNP200 caused an obvious decrease of ALP activity, mineralization formation and the expressions of osteo-/dentinogenic genes including RUNX2, DSPP, DMP1 and BSP. Meanwhile, CFSE and cell cycle assays revealed that knock-down of SNRNP200 inhibited the cell proliferation and blocked cell cycle at the G2/M and S phase in SCAPs. In addition, it was found that depletion of SNRNP200 up-regulated p21 and p53, and down-regulated the CDK1, CyclinB, CyclinE and CDK2. Conclusions: Depletion of SNRNP200 repressed osteo-/dentinogenic differentiation potentials and restrained cell proliferation through blocking cell cycle progression at the G2/M and S phase, further revealing that SNRNP200 has crucial effects on preserving the proliferation and differentiation potentials of dental tissue-derived MSCs.

Discrimination of botanical origin of olive oil from selected Greek cultivars by SPME-GC-MS and ATR-FTIR spectroscopy combined with chemometrics

BACKGROUND Consumers today wish to know the botanical origin of the olive oil they purchase. The objective of the present study was the development of robust chemometric models based on gas chromatography-mass spectrometry (GC-MS) and attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) for the purpose of botanical differentiation of three commercial Greek olive oil cultivars. RESULTS Using the solid-phase microextraction technique (SPME), volatile compounds (VC) were obtained and analyzed by GC-MS. Five hydrocarbons and one ester were selected by the forward stepwise algorithm, which best discriminated the olive oil samples. From ATR-FTIR analysis, the spectral regions chosen from the forward stepwise algorithm were associated with C(sic)O stretching vibration of the esters of triglycerides and the C-H bending vibrations of the CH2 aliphatic group and double bonds. Application of the supervised methods of linear and quadratic discriminant cross-validation analysis, based on VC data, provided a correct classification score of 97.4% and 100.0%, respectively. Corresponding statistical analyses were used in the mid-infrared spectra, by which 96.1% of samples were discriminated correctly. CONCLUSION ATR-FTIR and SPME-GC-MS techniques in conjunction with the appropriate feature selection algorithm and classification methods proved to be powerful tools for the authentication of Greek olive oil. The proposed methodology could be used in an industrial setting for determination of the botanical origin of Greek olive oil. (c) 2020 Society of Chemical Industry
