Policosanols is a health promoting aliphatic alcohol known as lipid-lowing agent. To enable maximising the functional properties of wheat, this research investigates the policosanol profiles and adenosine 5'-monophosphate-activated protein kinase (AMPK) activation potential of Korean wheat seedlings according to cultivars and growth times. GC-MS revealed six policosanols that differed markedly in content between 17 cultivars, especially, octacosanol (8) showed the most predominant component (49-83%), varying significantly in average concentrations with growth times as 361.4 (3 days) → 613.0 (6 days) → 203.1 (9 days) → 196.5 (12 days) → 50.9 mg/100 g (19 days). The highest average policosanol (738.7 mg/100 g) exhibited after 6 days, while the lowest was 104.4 mg/100 g on 19 days. Moreover, the wheat cultivars including Shinmichal 1, Anbaek, Namhae, and Joah at 6 days may be recommended as potential sources because of high policosanols (921.7-990.6 mg/100 g). Western blot analysis revealed markedly higher AMPK activation in cells treated with the hexane extracts (150-370% at 100 μg/ml) and octacosanol (8) possessed potent AMPK activator (control; 100 → 280% at 200 μg/ml). It is confirmed that the AMPK activation by wheat seedlings are positively related to the highest policosanol content at the 6 days of growth time, independent of the cultivar. Our results may be contributed to enhance the wheat value regarding development of new cultivars and functional foods. The odour-active compounds of feijoa (Acca sellowiana), were isolated by Solvent-Assisted Flavour Evaporation (SAFE). By application of GC-O and the aroma extract dilution analysis (AEDA), nineteen odorants were detected. Volatile compounds with highest flavour dilution (FD) factor were quantified by internal standard and relative response factor. On the basis of the quantitative data and odour thresholds in water, odour activity values (OAV) were calculated. High OAVs were determined for ethyl butanoate, Z-3-hexenal, linalool and methyl benzoate responsible for the fruity, green, flowery and medicinal notes. A recombination assay and omission tests, showed the relevance of Z-3-hexenal, linalool and methyl benzoate as odour active compounds in feijoa aroma. Headspace solid-phase microextraction (HS-SPME) was used in order to verified linalool enantiomeric distribution in two feijoa varieties. R-linalool was the major configuration in both varieties. Quimba variety showed an enantiomeric ratio 7525 while for Mammoth variety, linalool enantiomeric ratio was 955 (RS). We and others have identified biomarker candidates of tenderness or marbling, two major attributes of bovine meat-eating qualities for consumers' satisfaction. In this study, Reverse Phase Protein Arrays (RPPA) and targeted mass spectrometry assays using Parallel Reaction Monitoring (PRM) were developed to test whether 10 proteins pass the sequential qualification and verification steps of the challenging biomarker discovery pipeline. At least MYH1, TPI1, ALDH1A1 and CRYAB were qualified by RPPA or PRM as being differentially abundant according to marbling values of longissimus thoracis and semimembranosus muscles. Significant mathematical relationships between the individual abundance of each of the four proteins and marbling values were verified by linear or logistic regressions. Four proteins, TNNT1, MDH1, PRDX6 and ENO3 were qualified and verified for tenderness, and the abundance of MDH1 explained 49% of the tenderness variability. The present PRM and RPPA results pave the way for development of useful meat industrial multiplex-proteins assays. The effect of supercritical carbon dioxide (SCCD) treatment at varying processing time (30-90 min) on foaming and structure properties of egg white protein (EWP) were studied in this paper. The highest foaming ability (107.7%) was obtained after 60 min SCCD treatment, which was 3.6-fold to the control group. Foaming stability kept stable under the processing time of 75 min. Results of surface tension, surface hydrophobicity, rheological properties and particle size indicated that protein was easier to spread to the gas-liquid interface and generate molecular rearrangement. Circular dichroism (CD) and Endogenous fluorescence spectrum showed that there were slight changes on the secondary structure of EWP. The α-helical structure of the protein was destroyed and the particle size became uneven, which indicated that the protein structure became more flexible and loose. The results of this study indicate that SCCD treatment had a potential to be implemented to enhance foaming properties of EWP. The impact of nanoemulsions containing triglycerides with different fatty acid chain lengths on the bioavailability of a highly lipophilic bioactive 5-demethylnobiletin (5-DN) was investigated. 5-DN was encapsulated in nanoemulsions fabricated using either medium-chain triglycerides (MCT) or long-chain triglycerides (LCT). They were then subjected to in vitro digestion, and the resulting mixed micelles was applied to a Caco-2 cell model. Higher 5-DN bioaccessibility was found for the MCT-nanoemulsion (13%) than for the LCT-nanoemulsion (7%). However, only 30% 5-DN in MCT crossed the Caco-2 monolayer and 50% was metabolized, while 60% 5-DN in LCT crossed the monolayer and only 10% was metabolized. selleck chemicals More lipid droplets and chylomicrons were also formed for the LCT nanoemulsions, indicating greater 5-DN transported through lymph. Although MCT gave a higher 5-DN bioaccessibility, the final amount of 5-DN absorbed and transported to the lymph was inferior to that of the LCT formulation. CUL4B gene encodes a scaffold protein that assembles the CRL4B ubiquitin ligase complex, and its mutation can causes X-Linked Mental Retardation (XLMR) emerged with intellectual deficit, delayed puberty, short stature and fine intention tremor. Here we report the generation of SDUBMSi002-A, an induced pluripotent stem cell line derived from patient with c. 1564C→T with CUL4B gene using non-integrative reprogramming technology. The iPSCs line expresses pluripotent markers, has a normal male karyotype and can differentiate into the three germ layers.
