Design of polymeric core-shell carriers for combination therapies

Particle engineering for co-delivery of drugs has the potential to combine multiple drugs with different pharmaceutical mechanisms within the same carrier, increasing the therapeutic efficiency while improving patient compliance. This work proposes a novel approach for producing polymer-polymer core-shell microparticles by multi-step processing of emulsion and spray drying. The particle core was obtained by an oil-in-water emulsion of poly(e-caprolactone) (PCL) loaded with curcumin (CM), followed by the resuspension in poly(vinyl alcohol) (PVA) containing ciprofloxacin (CPx) forming the shell layer by spray-drying. The obtained core-shell particles showed an average size of 3.8 +/- 1.2 mu m, which is a suitable size for inhalation therapies. The spatial distribution of the drugs was studied using synchrotron-based macro attenuated total reflection Fourier transform infrared (macro ATR-FTIR) microspectroscopy to map the chemical distribution of the components within the particles and supported the presence of CM and CPx in the core and shell layers, respectively. The formation of the core-shell structure was further supported by the differences in the release profile of CM from these particles, when compared to the release profile observed for the single particle structure (PCL-CM). Both empty and drug-loaded carriers (up to 100 mu g.mL(-1)) showed no cytotoxic effects on A549 cells while exhibiting the antibacterial activity of CPx against Gram-positive and Gram-negative bacteria. These polymer core-shell microparticles provide a promising route for the combination and sequential drug release therapies, with the potential to be used in inhalation therapies.

Progress in alcohol-gasoline blends and their effects on the performance and emissions in SI engines under different operating conditions

Bio-alcohol has the potential to be used as an alternative to fossil fuels to reduce the total exhaust emissions from spark-ignition engines. This paper reviewed the most recent experimental studies on fundamental effects of performance, emissions and some combustion characteristics in SI engines. It also provides a guideline for suitable ethanol-gasoline and methanol-gasoline blend rates. Investigations were performed on different engines, operating conditions and rates of fuel blends with varying engine speeds. Most of the results showed that ethanol-gasoline has more benefits compared to methanol-gasoline in terms of exhaust emissions, engine power, and torque output, especially at low engine speed. The small differences in properties between ethanol-gasoline and methanol-gasoline blends are enough to create a significant change in the combustion system. These effects lead to behavioural mechanisms which are not easy to analyze or understand, sometimes make it difficult to identify the fundamentals of how ethanol or methanol affects emissions.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 112-47-0. HPLC of Formula: C10H22O2.

Assimilable nitrogen reduces the higher alcohols content of huangjiu

Yeast assimilable nitrogen (YAN) sources play an important role in the formation of higher alcohols in wine. In this study, the types and amounts of YAN sources and the genes that regulate the synthesis of higher alcohols in a yeast used for huangjiu brewing, Saccharomyces cerevisiae HJ, were assessed for the first time. Quantitative realtime PCR experiments demonstrated that S. cerevisiae HJ genes controlling the production of higher alcohols were expressed at significantly different levels during different growth stages and at different YAN levels, indicating that YAN significantly impacts the total higher alcohols concentration of huangjiu. Ammonium salts especially NH4Cl showed greater effect in reducing the content of higher alcohols than amino acids or urea. After optimization, the addition of NH4Cl (200 mg/L) most effectively reduced the content of higher alcohols at the end of fermentation with little effect on the cell growth rate, final cell density and ethanol concentration. Total higher alcohols decreased by 39%, while the concentrations of isobutanol, isoamylol and 2-phenylethanol decreased by 47%, 28%, and 44%, respectively. The addition of NH4Cl promoted the formation of esters and enriched the amino acids in huangjiu. This study provides a new insight to control the quality of huangjiu, especially the content of higher alcohols based on the strategy of adding NH4Cl.

Microalgal secondary metabolites: effect of climatic variables, seasons, and photocycles on the biogeneration of volatile organic compounds (VOCs)

Microalgae produce many metabolites with diversified structures that play important roles in their development. This work evaluated the effects of different climatic variables, seasons, and light/dark phases in the production of volatile organic compounds by Scenedesmus obliquus CPCC05, focusing on the simulation of climatic variables (average temperature, maximum light intensity, and light hours per day) of the extreme geographical positions of Brazil based on tropical Am, tropical Aw, and subtropical Cfa climates found in Joao Pessoa-PB, Rio Branco-AC, Boa Vista-RR, and Rio Grande-RS, in summer and winter seasons. For the best condition in this first step, the light/dark phases together with the residence time of the culture were evaluated. A total of 45 compounds were identified in all conditions studied. The main volatile groups found were hydrocarbons, aldehydes, ketones, alcohols, and terpenes identified in both geographic locations. Among these, hydrocarbons were the main biomarkers of the subtropical Cfa climate, while the ketone group was produced mainly in warmer climates, such as the Aw tropical climate. In the experiments of light/dark phases, a total of 34 compounds were identified. 2-Pentenol and decanal were only produced in the light phase, while 1-pentanol and 2-ethyl hexanol were only found in the dark phase. The main volatile compound found was 3-methylbutanol reaching a total area abundance of 14.10%. The major compounds detected during the cultures were originated and derived from the terpenoid pathways, fatty acids, and amino acid derivates.

Selective electrooxidation of 2-propanol on Pt nanoparticles supported on Co3O4: an in-situ study on atomically defined model systems

2-Propanol and its dehydrogenated counterpart acetone can be used as a rechargeable electrofuel. The concept involves selective oxidation of 2-propanol to acetone in a fuel cell coupled with reverse catalytic hydrogenation of acetone to 2-propanol in a closed cycle. We studied electrocatalytic oxidation of 2-propanol on complex model Pt/Co3O4(111) electrocatalysts prepared in ultra-high vacuum and characterized by scanning tunneling microscopy. The electrocatalytic behavior of the model electrocatalysts has been investigated in alkaline media (pH 10, phosphate buffer) by means of electrochemical infrared reflection absorption spectroscopy and ex-situ emersion synchrotron radiation photoelectron spectroscopy as a function of Pt particle size and compared with the electrocatalytic behavior of Pt(111) and pristine Co3O4(111) electrodes under similar conditions. We found that the Co3O4(111) film is inactive towards electrochemical oxidation of 2-propanol under the electrochemical conditions (0.3-1.1 V-RHE). The electrochemical oxidation of 2-propanol readily occurs on Pt(111) yielding acetone at an onset potential of 0.4 V-RHE. The reaction pathway does not involve CO but yields strongly adsorbed acetone species leading to a partial poisoning of the surface sites. On model Pt/Co3O4(111) electrocatalysts, we observed distinct metal support interactions and particle size effects associated with the charge transfer at the metal/oxide interface. We found that ultra-small Pt particles (around 1 nm and below) consist of partially oxidized Pt-delta(+) species which show minor activity towards 2-propanol oxidation. In contrast, conventional Pt particles (particle size of a few nm) are mainly metallic and show high activity toward 2-propanol oxidation.

Automatic cognitions as mediators of parental influence on adolescent cannabis use

Aims: Multiple social influences affect cannabis use in adolescents, including parental and peer cannabis use norms. However, the mechanisms of influence underlying these social influences remain unclear. Recent studies have suggested that cognitions about cannabis use and the effects of cannabis may mediate social influences. The current study explored the relationship between automatic self-generated cognitions and their relationship with parental influences on cannabis use in a sample of n = 675 11 to 16-year-old adolescents over three years (Mean Age: 13.96, SD = 0.88, 56.4% female). Methods: Participants reported perceptions of parental cannabis use and completed a cannabis word association task (CWAT), an open-ended cannabis outcome expectancy liking (COEL) task, and measures of cannabis use in the past year. Results: Perceived parental use did not directly predict cannabis use two years later. However, a latent construct loading on both CWAT and COEL scores strongly predicted cannabis use over the following year. Structural modelling demonstrated that the association between previous cannabis use and parental cannabis use and adolescents’ cannabis use over the next two years was fully mediated by cognitions. Conclusion: The results of the study are discussed and interpreted through the lens of dual-process theories.

Design and synthesis of novel amphipathic ionic liquids for biodiesel production from soapberry oil

Biodiesel produced from non-edible oils has received intensive attention in recent years. Herein, a series of novel amphipathic ionic liquids (ILs) based on the 4-dimethylaminopyridine (DMAP) were prepared for the transesterification of soapberry oil and methanol. The structures of the prepared ILs were systematically characterized by both Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (NMR, H-1 NMR and C-13 NMR). In addition, the effects of side-chain length of cation and the number of active site (H+) of ILs on the biodiesel yield were investigated, and the results suggested that 1-dodecyl-(4-dimethylammonium)-pyridinium bisulfate ([C12-DMAPH][HSO4](2)) exhibited the highest catalytic efficiency. Meanwhile, [C12-DMAPH][HSO4](2) was proven to be amphipathic, and the corresponding catalytic mechanism was proposed. Under the catalysis of [C12-DMAPH][HSO4](2), the optimum operating conditions of transesterification of soapberry oil and methanol were explored via the combination of single factor experiment and response surface methodology, obtaining the high biodiesel yield of (98.02 +/- 0.36)% under the optimum operating conditions. Importantly, [C12-DMAPH][HSO4](2) exhibited high stability in the transesterification of soapberry oil and methanol in five consecutive runs. Furthermore, the catalytic activities of [C12-DMAPH][HSO4](2) towards other transesterification of non edible oils and lower alcohols were also investigated, which indicated a general applicability of the prepared IL.

Enantiomer composition of chiral compounds present in traditional Slovak Tokaj wines

In the presented study volatile organic compounds (VOC) profiles of the most valuable products from Slovak Tokaj wine region were characterized using SPME-GC-MS. Identified volatile organic compounds in studied samples of Tokaj selection wines and Tokaj essences belonged to esters, terpenes, higher alcohols, volatile acids, lactones and aldehydes. From identified VOC, chiral compounds were selected, and their enantiomers were separated by heart-cut two-dimensional GC system. Enantiomer separation was optimized, and this advanced method was applied to determine enantiomeric ratios (ER) of studied compounds in 53 traditional botrytized Tokaj wines. Terpenic compounds linalool and limonene were present in ER resembling the racemic mixture, hotrienol expressed the slight dominancy of S-enantiomer (51-82 %) and S-alpha-terpineol varied from 47 to 70 %. Moreover, linalool and limonene were present only in wines of younger vintages. ER of 2,3-butanediol has shown the predominance of 2R,3R-enantiomer in all samples even though reached also values that were not usual for common white wines (55-100 %). Whiskey lactones were identified in all wines aged in oak barrels and exclusive presence of (4S,5S)-cisand (4S,5R)-transenantiomers was confirmed.
