Diastereoselective Synthesis of Aryl C-Glycosides from Glycosyl Esters via C-O Bond Homolysis

C-aryl glycosyl compounds offer better in vivo stability relative to O- and N-glycoside analogues. C-aryl glycosides are extensively investigated as drug candidates and applied to chemical biology studies. Previously, C-aryl glycosides were derived from lactones, glycals, glycosyl stannanes, and halides, via methods displaying various limitations with respect to the scope, functional-group compatibility, and practicality. Challenges remain in the synthesis of C-aryl nucleosides and 2-deoxysugars from easily accessible carbohydrate precursors. Herein, we report a cross-coupling method to prepare C-aryl and heteroaryl glycosides, including nucleosides and 2-deoxysugars, from glycosyl esters and bromoarenes. Activation of the carbohydrate substrates leverages dihydropyridine (DHP) as an activating group followed by decarboxylation to generate a glycosyl radical via C-O bond homolysis. This strategy represents a new means to activate alcohols as a cross-coupling partner. The convenient preparation of glycosyl esters and their stability exemplifies the potential of this method in medicinal chemistry.

Enrichment and retention of key functional bacteria of partial denitrification-Anammox (PD/A) process via cell immobilization: A novel strategy for fast PD/A application

Cell immobilization was used to enrich and retain functional bacteria within partial denitrification-Anammox (PD/A) process to achieve its fast start-up for the first time. To do so, residue sludge and Anammox sludge were immobilized in poly (vinyl alcohol)/sodium alginate (PVA/SA) gel for PD cultivation and Anammox bacteria inoculation, respectively. Stable PD with NO3–N to NO2–N transformation ratio (NTR) of 72.0% was achieved within 13 days at 25 degrees C and successfully combined with Anammox on 14th day. The hydrous porous PVA/ SA gel matrix played the role of extracellular polymeric substance (EPS) and thus protected the microbes against low temperature. Satisfactory nitrogen removal rate (NRR) (301.6 +/- 6.1 g N/(m(3).d)) was achieved even when temperature decreased to 13 degrees C. The contribution of nitrogen removal via Anammox was as high as 77.10%. Abundance of Thauera and Candidatus Kuenenia increased from 0.9% and 1.1% to 30.6% and 2.1%, respectively.

Destabilization mechanism of (W-1+W-2 )/O reverse Janus emulsions

Hypothesis: Reverse Janus emulsion, with droplets composed by two rooms of water phases, is a novel multiple emulsion attributed to excellent integration capability and biocompatibility. However, significant instability compared with normal Janus emulsions renders the stability issue of great importance. Moreover, the ultra-low aqueous-aqueous inner interfacial tension, the anisotropic nature of the droplets with distinct lobe composition, and the random orientation in the continuous phase endow the complicated and various demulsification mechanisms. Experiments: Reverse Janus emulsion of (W-1+W-2)/O, employing typical salt-alcohol aqueous two-phase system (ATPS) as inner phases, is prepared in batch scale by conventional one-step vortex mixing. The demulsification process is detected by multiple light scattering technique, which provides real-time, in-situ, and quantitative information of emulsion evolution. Moreover, the fusion pattern of the anisotropic droplets is illustrated by the combination with light microscopy and size distribution measurement. Findings: Coalescence and sedimentation are found to be two main demulsification processes. Two salt body lobes of the snowman shaped Janus droplets combine first resulting in an intermediate Cerberus topology with two alcohol heads on one salt body. Subsequently, two head lobes coalesce resulting in a larger Janus droplet. Ultimately, the Gibbs free energy leads to a final state with three separated liquids. In addition, the variation in lobe viscosity, density, and properties of interfacial film greatly affect the demulsification rate and fusion pattern. A critical alcohol/surfactant mass ratio of 2 is found, beyond which a completely different fusion pattern occurs. Two alcohol body lobes combine first resulting in an intermediate Cerberus topology with two salt heads on one alcohol body. Subsequently, two head lobes coalesce resulting in a larger Janus droplet. The findings are instructive in the stability of aqueous based multiple emulsions with advanced morphologies and meanwhile, promote the future application of this novel emulsion in food science, pharmacy, and biomimetic compartmentalization.

Formation mechanism and environmental stability of whey protein isolate-zein core-shell complex nanoparticles using the pH-shifting method

The alcohol-free pH-shifting method was applied to fabricate stable complex nanoparticles from hydrophilic whey protein isolate (WPI) and hydrophobic zein, which was aimed to develop a strategy to obtain desirable physicochemical stability. When the mass ratio of WPI and zein was elevated from 9:1 to 1:1, the size of WPI-zein complex nanoparticles was increased from 90 to 150 nm. The complex nanoparticle showed desirable storage stability (28 days) and physical stability, as well as excellent stability against various environmental stresses (heat, pH and ionic strength). The analysis of FTIR and the nanoparticle dissociation test revealed that hydrophobic effects and electrostatic attraction played an important role in the formation of WPI-zein complex nanoparticles. The transmission electron microscope (TEM) images evidenced the core-shell structure of WPI-zein complex nanoparticles with a regular spherical shape. The findings showed the feasibility of the simple pH-shifting method to fabricate the protein-based complex nanoparticles, which were expected to be further applied in the delivery of bioactive compounds.

Release of catechin from Azivash gum-polyvinyl alcohol electrospun nanofibers in simulated food and digestion media

In this study, the electrospinning process was applied for the encapsulation of catechin in nanofibers from Azivash (Corchorus olitorius. L) gum-polyvinyl alcohol. By increasing catechin concentration (from 500 to 1000 mg L-1), encapsulation efficiency was lowered but loading capacity increased. A positive correlation was observed between catechin addition and diameter of nanofibers. FTIR spectroscopy highlighted the interactions between catechin and polymer solution which increased the thermal stability of nanofibers. Results of release trends demonstrated that approximately 50% and <70% of the total catechin was released in simulated gastric fluid and simulated intestinal fluid, respectively. Also, a different catechin release rate from nanofibers was observed in simulated low-fat and high-fat food media, respectively. After 12 days, about 90% of the total catechin was released. It was confirmed that designed nanofibers have the capacity to be applied in active packaging for improving the oxidative stability of food and pharmaceutical products.

The carbon footprint of alternative jet fuels produced in Brazil: exploring different approaches

Although the potential of Alternative Jet Fuels (AJF) to reduce greenhouse gases (GHG) emissions has been widely reported upon in the literature, there are still discrepancies among the results. These may be due to the different GHG accounting methods, including those used by different Low-Carbon Policies (LCPs). To have a clearer understanding of the life cycle performance of AJF, the carbon footprint of ten pathways was estimated, comprising promising feedstocks – such as soybean, palm, sugarcane, sugarcane residues, forestry residues, used cooking oil, beef tallow, and steel off-gases – and ASTM-approved technologies: Hydroprocessed Fatty Acids, Alcohol-to-Jet, and Fischer-Tropsch. Six methodological approaches were used: the attributional and the consequential life cycle assessment, as well as guidelines for the four LCPs: Renovabio (Brazil), CORSIA (aviation sector), RFS (United States), and RED II (Europe). Soybean-based pathway (24 to 98.7 gCO(2e)/MJ) had the low to no potential for reducing GHG when compared to their fossil counterparts, mainly due to land use change. Of all food-based pathways, AJF produced from sugarcane performed the best (-10.4 to 43.7 gCO(2e)/MJ), especially when power surplus was credited. AJF from palm oil could present significant GHG reduction for palm expansion in degraded pasturelands. By contrast, Fischer-Tropsch of lignocellulosic residues showed the highest potential for reducing GHG (-95% to -130%). Different from food-based pathways, the potential GHG reduction of residues-based pathways converged within a narrower range (-130% to -50%), except when residual feedstocks have to be redirected from their current economic use. It could lead to GHG emissions higher than fossil fuel.

MOF-derived well-structured bimetallic catalyst for highly selective conversion of furfural

Selective conversion of furfural can produce some important chemical intermediates. However, it is a challenge to design suitable catalysts due to the complex reaction route. A series highly dispersed Co-Ni alloy NPs embedded in porous nitrogen-containing carbon matrix multifunctional catalysts (xCo-yNi@NC) were prepared by pyrolysis of MOF template. The characterization results showed that Co-Ni alloy presented strong bimetallic synergistic effect and introduction of N species influenced the physicochemical properties of the catalyst, hence promoted the catalytic performance. Moreover, Lewis acid sites provided by metal oxide species can polarize the C=O bond via lone pair electrons on the oxygen atom, which contribute to furfuryl alcohol formation and accelerate furfuryl alcohol rearrangement to 4-hydroxy-2-cycloentenone. In addition, the solvent played an important role in the product distribution. Under the optimized reaction conditions, 99.0% furfuryl alcohol yield was obtained in methanol solvent, while 92.5% cyclopentanone yield was obtained in water solvent over 2Co-1Ni@NC.

Multidimensional elements of impulsivity as shared and unique risk factors for food addiction and alcohol misuse

Food addiction (FA) and alcohol misuse tend to co-occur, which suggests shared factors in the etiology and persistence of these health behaviors. One shared factor that has been linked to both is impulsivity, a multidimensional construct reflecting multiple facets of self-regulatory capacity. However, co-occurrence also raises issues of possible confounding if both domains are not considered concurrently, and the intersection between FA, alcohol misuse, and impulsivity has not been well characterized empirically. Therefore, the current study examined the intersection of FA, alcohol consequences, and multiple indicators of impulsivity. Participants were emerging adults reporting regular heavy episodic drinking recruited from Hamilton, Ontario (N = 730; ages 19.5-23). Participants completed measures of FA, alcohol problems, impulsive personality traits (i.e., Barratt Impulsiveness Scales, UPPS-P Impulsive Behavior Scales), impulsive choice (i.e., delay discounting), impulsive action (i.e., Go/NoGo task). Findings revealed a significant association between FA and alcohol-related consequences and both shared similar associations with specific impulsive personality traits (Positive and Negative Urgency, Lack of Premeditation, Motor and Attentional Impulsivity). However, alcohol-related consequences were uniquely associated with other impulsive personality traits (Lack of Perseverance, Sensation Seeking, Non-planning impulsivity) and impulsive choice, and FA was uniquely associated with impulsive action. Beyond alcohol-related consequences, FA was associated with additional variance in measures of impulsive personality traits (Positive and Negative Urgency, Lack of Premeditation, Motor Impulsivity, and Attentional Impulsivity) and impulsive action, but not impulsive choice. Overall, the current study reveals several common self-regulatory processes associated with both adverse drinking consequences and FA, and that the risk of inadvertent confounding appears to be limited.

One-year Follow-Up Results with Hydrogel Implant in Therapy of Hallux Rigidus: Case Series with 44 Patients

Background The Cartiva implant (CI) is being increasingly used in the surgical therapy of hallux rigidus. Despite a growing number of studies, numerous questions regarding patient selection remain unanswered. Patients and Methods As part of a retrospective case series with prospective follow-up (average follow-up period: 12 months), a total of 44 patients (male/female = 16/28; mean age at the time of surgery: 55.4 years) with 44 CI were analysed (VAS, EFAS-, AOFAS-score). Using a correlation analysis and a machine learning algorithm, risk factors for therapy failure were investigated. Results The overall survival rate of the CI was 93% at 12 months. The VAS, EFAS and AOFAS scores showed a significant improvement in comparison to the preoperative condition. The mobility of the metatarsophalangeal joint showed no increase. Patients with a medium osteoarthritis grade and a medium level of clinical restraint showed the greatest improvement in relation to their preoperative condition. Conclusion The CI can be seen as an effective therapy for hallux rigidus. Nonetheless, realistic patient expectations must be communicated.
