Goh, Andrea Shi’en;Ningtyas, Dian Widya;Bhandari, Bhesh;Prakash, Sangeeta research published 《 Investigating phytosterol as a potential functional component in milk through textural, flavour and oral perception study》, the research content is summarized as follows. Phytosterols (PS) are functional ingredients capable of providing health benefits. This study investigated the potential of incorporating different levels of PS ester (0.8, 1.2, 1.6 and 2.0 g/100 g) into skim milk (0.1 g/100 mL milk fat) to replace the milk fat. PS-enriched milk were analyzed for its phys. characteristics (color, viscosity, tribol., particle size and microstructure) and compared to com. milk (0.1, 1.3, 2 g/100 mL fat, and 1.3 g/100 mL fat with 0.3 g/100 mL PS). Furthermore, the flavor profiles and sensory acceptability of the PS-enriched milk were evaluated. All samples exhibited a characteristic shear-thinning flow behavior, with 2 g/100 g PS ester milk displaying the highest viscosity (4.46 ± 1.93 mPa s) at 50/s shear rate and 35°C. Confocal images and particle size distribution suggest fat coalescence resulting in larger fat globules (0.53 ± 0.14μm) in 2 g/100 g PS ester milk. In general, the addition of PS ester increased the fatty acid and aldehyde compounds of PS-enriched milk, providing comparable lubrication properties and whiteness to com. milk with the same fat levels. Sensory evaluation revealed that the PS-enriched milk did not possess any off-flavor and milk with 1.6 g/100 g PS ester were the most preferred.

Gonzalez-Dominguez, Raul;Sayago, Ana;Santos-Martin, Maria;Fernandez-Recamales, Angeles research published 《 High-Throughput Method for Wide-Coverage and Quantitative Phenolic Fingerprinting in Plant-Origin Foods and Urine Samples》, the research content is summarized as follows. The use of mass spectrometry is currently widespread in polyphenol research because of its sensitivity and selectivity, but its usual high cost, reduced robustness, and nonavailability in many anal. laboratories considerably hinder its routine implementation. Herein, we describe the optimization and validation of a high-throughput, wide-coverage, and robust metabolomics method based on reversed-phase ultra-high-performance liquid chromatog. with diode array detection for the identification and quantification of 69 phenolic compounds and related metabolites covering a broad chem. space of the characteristic secondary metabolome of plant foods. The method was satisfactorily validated following the Food and Drug Administration guidelines in terms of linearity (4-5 orders of magnitude), limits of quantification (0.007-3.6 mg L^-1), matrix effect (60.5-124.4%), accuracy (63.4-126.7%), intraday precision (0.1-9.6%), interday precision (0.6-13.7%), specificity, and carryover. Then, it was successfully applied to characterize the phenolic fingerprints of diverse food products (i.e., olive oil, red wine, strawberry) and biol. samples (i.e., urine), enabling not only the detection of many of the target compounds but also the semi-quantification of other phenolic metabolites tentatively identified based on their characteristic absorption spectra. Therefore, this method represents one step further toward time-efficient and low-cost polyphenol fingerprinting, with suitable applicability in the food industry to ensure food quality, safety, authenticity, and traceability.

Goo, Yoon Tae;Sa, Cheol-Ki;Kim, Min Song;Sin, Gi Hyeong;Kim, Chang Hyun;Kim, Hyeon Kyun;Kang, Myung Joo;Lee, Sangkil;Choi, Young Wook research published 《 Enhanced dissolution and bioavailability of revaprazan using self-nanoemulsifying drug delivery system》, the research content is summarized as follows. A self-nanoemulsifying drug delivery system (SNEDDS) was developed to enhance the dissolution and oral bioavailability (BA) of revaprazan (RVP). Various SNEDDSs containing 200 mg of RVP were formulated using Capmul MCM, Tween 80, and Brij L4, and they were characterized according to their size, polydispersity index, and dissolution behavior. Dissolution rates of all SNEDDS formulations significantly (p < 0.05) improved with the formation of nanoemulsion with monodispersity. Formulation D resulted in RVP dissolution exceeding 70% at 2 h. Compared to raw RVP, SNEDDS exhibited a 4.8- to 7.4-fold improved effective permeability coefficient (Peff) throughout the intestine in the in situ single pass intestinal permeability study and a 5.1-fold increased oral BA in the in vivo oral absorption assessment in rats. To evaluate the degree of lymphatic uptake, cycloheximide (CYC), a chylomicron flowing blocker, was pretreated prior to the experiment This pretreatment barely affected the absorption of raw RVP; however, it greatly influenced the absorption of SNEDDS, resulting in an approx. 40% reduction in both the Peff value and oral BA representing lymphatic transport. Thus, we suggest that the SNEDDS formulation is a good candidate for improving oral absorption of RVP through enhanced lymphatic uptake.

Anthocyanin, an essential ingredient of functional foods, is present in a wide range of plants, including black carrots. The current investigation was carried out to analyze the effect of cold stress on the expression of major anthocyanins and anthocyanin biosynthetic pathway genes, MYB6 and LDOX-1. Methods and results: Five cultivated carrot genotypes belonging to the eastern group, having anthocyanin pigment, were used in the current study. The qRT-PCR anal. revealed that relative gene expression of transcription factor MYB-6 and LDOX1gene was highly expressed upon cold stress compared to non-stress samples. High-performance liquid chromatog.-based quantification of Cyanidin 3–glucoside (Kuromanin chloride), Ferulic acid, 3,5-Dimethoxy-4-hydroxycinnamic acid (Sinapic acid), and Rutin revealed a significant increase in these major anthocyanins in response to cold stress when compared to control plants. Conclusion: We conclude that MYB6 and LDOX1 gene expression increases upon cold stress, which induces accumulation of major anthocyanins in purple black carrot and suggests a possible cross-link between cold stress and anthocyanin biosynthesis in purple black carrot.

Darwish, Khaled M.;Abdelwaly, Ahmad;Atta, Asmaa M.;Helal, Mohamed A. research published 《 Discovery of tetrahydro-β-carboline- and indole-based derivatives as promising phosphodiesterase-4 inhibitors: Synthesis, biological evaluation, and molecular modeling studies》, the research content is summarized as follows. Phosphodiesterase-4 (PDE4) is responsible for the selective degradation of the 3′-cyclic phosphate bonds of cAMP. A collection of twenty-three diverse 1,2,3,4-tertahydro-β-carboline- and indole-based analogs were synthesized and assessed for their inhibitory activity against human PDE4. The compounds were prepared using straightforward procedures and characterized using ¹H- and ¹³C NMR, IR, and mass spectroscopy as well as elemental anal. Fifteen of the prepared compounds exhibited significant inhibitory activity with IC₅₀ values in the lower micromolar to upper nanomolar ranges. The most active compounds also showed good selectivity for PDE4 over the related enzyme family member, PDE5, with either insignificant or null% inhibition of the latter enzyme. The indole-based compounds, 21b (I) and 21c (II), showed the most pronounced PDE4 inhibition with IC₅₀ values of 754 and 664 nM, resp. The PDE4B active site comprises both hydrophobic and solvent-filled pockets. The hydrophobic pocket (Q) includes the invariant purine-selective Gln443 which is critical for cAMP. Below this Gln443 lies Phe446 which acts as a hydrophobic P-clamp stabilizing the ligand aromatic ring system. Mol. docking investigation showed preferential anchoring of the active compounds within the PDE4 active site through interactions between the indole nitrogens and the dimethoxy Ph groups with key residues. Overall, the prepared compounds are novel and simple mols. with good potential for future optimization. Showing satisfactory predicted ADME/safety and drug-likeness properties, compound 21c is considered a promising lead for further optimization towards clin. investigation against inflammatory, auto-immune diseases, or certain types of cancer.

Daryab, Mahshid;Faizi, Mehrdad;Mahboubi, Arash;Aboofazeli, Reza research published 《 Preparation and characterization of lidocaine-loaded, microemulsion-based topical gels》, the research content is summarized as follows. Microemulsion-based gels (MBGs) were prepared for transdermal delivery of lidocaine and evaluated for their potential for local anesthesia. Lidocaine solubility was measured in various oils, and phase diagrams were constructed to map the concentration range of oil, surfactant, cosurfactant, and water for oil-in-water (o/w) microemulsion (ME) domains, employing the water titration method at different surfactant/cosurfactant weight ratios. Refractive index, elec. conductivity, droplet size, zeta potential, pH, viscosity, and stability of fluid o/w MEs were evaluated. Carbomer 940 was incorporated into the fluid drug-loaded MEs as a gelling agent. Microemulsion-based gels were characterized for spreadability, pH, viscosity, and in-vitro drug release measurements, and based on the results obtained, the best MBGs were selected and subsequently subjected to ex-vivo rat skin permeation anesthetic effect and irritation studies. Data indicated the formation of nano-sized droplets of MEs ranging from 20-52 nm with a polydispersity of less than 0.5. In-vitro release and ex-vivo permeation studies on MBGs showed significantly higher drug release and permeation in comparison to the marketed topical gel. Developed MBG formulations demonstrated greater potential for transdermal delivery of lidocaine and advantage over the com. available gel product, and therefore, they may be considered as potential vehicles for the topical delivery of lidocaine.
