86, 4.53), 3.58-fold (95% CI 3.34, 3.84), 3.53-fold (95% CI 3.28, 3.81), 4.02-fold (95% CI 3.72, 4.35), 3.89-fold (95% CI 3.59, 4.23), 3.87-fold (95% CI 3.62, 4.14) increase in prevalent hypertension, respectively, compared to non-obese individuals with low PM1 concentrations; similar results were observed for combined effect of PM2.5, PM10 or NO2 and obesity indices on prevalent hypertension. The significant values of RERI, AP and S indicated additive effects of air pollutants and obesity indices on hypertension. Obesity amplified the effects of exposure to high levels of air pollutants on increased BP values and prevalent hypertension, implying that obese individuals may be susceptible to elevate BP and prevalent hypertension in relation to air pollution exposure. CLINICAL TRIAL REGISTRATION The Henan Rural Cohort study has been registered at Chinese Clinical Trial Register (Registration number ChiCTR-OOC-15006699, http//www.chictr.org.cn/showproj.aspx?proj=11375).This paper describes the successful development of new low-immunoreactive buttermilk (BM)-based formulations which were fermented with 31 lactic acid bacteria (LAB) and Bifidobacterium strains. The aim of this study was to create a new formula, which can serve as potential candidates for the immunotherapy of allergy. Preparations were tested for their content of biologically active compounds, such as proteins, peptides, phospholipids, and short-chain fatty acids (SCFA), as well as for the survivability of LAB and sensory quality. The results showed that the BM was a matrix rich in nutritional components and displayed higher than expected susceptibility to the reduction of protein IgE-immunoreactivity (to 98%) and high bacterial-protecting capacity. The overall sensory quality of examined products was influenced by the profile of SCFA and free peptides, but two formulations fermented with Lactobacillus delbrueckii ssp. bulgaricus-151 and Lactobacillus casei-LcY were the most advantageous with desirable sensory, immunoreactive, and biochemical properties.The magnetic molecular imprinting polymers nanoparticles (MMIPs NPs) for the extraction of norfloxacin (NOR) were prepared by self-polymerization of dopamine onto the surface of (3-Aminopropyl)triethoxysilane (APTES)-modified Fe3O4 NPs. compound library chemical The MMIPs NPs were characterized by FT-IR spectroscopy, XRD, VSM and TEM. The characterization results show that the MMIPs NPs possess superparamagnetic characteristic with the saturated magnetization value of 38.6 emu/g, and the average particle size of about 14.3 nm. Furthermore, the adsorption performance of the MMIPs NPs was evaluated by the static, dynamic, selective adsorption and reusability experiments. The adsorption capacity of MMINs NPs for NOR is 14.2 mg/g with an imprinted factor of 2.1. About 82.4-102.4% of the added NOR (20, 40, 60 μg/mL) were recovered from fortified milk samples with MMIPs NPs as sorbent. Moreover, the MMIPs NPs can be reused for at least six times.Starch lamellar and crystalline structures are important controller of its physicochemical and digestion properties. Here, starch lamellar/crystalline structures of 16 different rice starches were investigated and correlated with their chain-length distributions (CLDs) and molecular size distributions. link2 Results showed that the thickness of amorphous lamellae was mainly correlated with the amount of amylose short and medium chains. Thickness of both amorphous and crystalline lamellae was negatively correlated with the amount of amylopectin medium chains and relative length of amylopectin short chains. The degree of crystallinity was negatively correlated with the amount of amylose short and long chains. The lamellar ordering, fractal nature and thickness polydispersity were also related to the starch CLDs. Whereas, starch molecular size distributions were shown to be lack of correlations with the starch lamellar/crystalline structures. This study helps a better understanding of the molecular nature of starch semi-crystalline lamellae.This study aims to determine toxic compounds polycyclic aromatic hydrocarbons (PAHs) and cholesterol oxidation products (COPs) in thin slices of dried pork as affected by different flavorings and roasting temperature treatments through employing a QuEChERS method coupled with gas chromatograph-tandem mass spectrometer (GC-MS/MS) and gas chromatograph-mass spectrometer (GC-MS), respectively. By employing this method, high accuracy and precision was attained for freeze-dried pork hind leg sample. Following addition of 8 different flavorings with roasting temperature at 120, 160, and 200 °C, the levels of total COPs and PAHs in thin slices of dried pork followed a temperature-dependent increase during roasting, which was further confirmed by principle component analysis. High level of soy sauce or sugar inhibited COP formation, while the low-level minimized PAH formation in thin slices of dried pork during roasting. Sugar was more effective in inhibiting COP formation while soy sauce was more efficient in reducing PAH formation.Erythorbyl myristate (EM), a potential multi-functional food emulsifier, was newly synthesized by immobilized lipase-catalyzed esterification between antioxidative erythorbic acid and antibacterial myristic acid. The yield and productivity of EM were 56.13 ± 2.51 mg EM/g myristic acid and 1.76 ± 0.08 mM/h, respectively. The molecular structure of EM was identified as (R)-2-((R)-3,4-dihydroxy-5-oxo-2,5-dihydrofuran-2-yl)-2-hydroxyethyl tetradecanoate using HPLC-ESI/MS and 2D [1H-1H] NMR COSY. The hydrophilic-lipophilic balance of EM was 11.5, suggesting that EM could be proper to stabilize oil-in-water emulsions. Moreover, isothermal titration calorimetry demonstrated the micellar thermodynamic behavior of EM and determined its critical micelle concentration (0.36 mM). In terms of antioxidative property, EM exhibited the radical scavenging activity against DPPH (EC50 35.47 ± 0.13 μM) and ABTS (EC50 36.45 ± 1.98 μM) radicals. Finally, EM showed bacteriostatic and bactericidal activities against Gram-positive foodborne pathogens (minimum inhibitory concentration 0.06-0.60 mM; minimum bactericidal concentration 0.07-0.93 mM).Recently, the interest in the plant proteases has greatly increased. However, only a few of proteases are isolated from the hugely produced oilseeds for the practical utilizations. In this study, the raw sesame milk prepared from peeled sesame seeds was separated into floating, skim, and precipitate fractions by centrifugation. The predominant aspartic endopeptidases and serine carboxypeptidases, which exerted high synergetic activity at pH 4.5-5 and 50-60 °C, were identified in the skim by the liquid chromatography tandem mass spectrometry, Tricine-sodium dodecyl sulfate-polyacrylamide gel electrophoresis, protease inhibitor assay, trichloroacetic acid-nitrogen soluble index (TCA-NSI), and free amino acid analyses. By incubating the mixture (protein content, 2%) of skim and precipitate at pH 4.5 and 50 °C for 6 h, the TCA-NSI and free amino acids achieved to 38.42% and 3148 mg/L, respectively. Moreover, these proteases efficiently degraded the proteins from soybean, peanut, and bovine milk.This study explored the impact of perceptual interactions on the odor intensity of 222 binary mixtures designed from 72 odorants found in food products. Odor intensity was rated by 30 trained subjects. The results showed that in most cases, the components' odor was perceived within the mixture and their intensity remained the same as in the unmixed situation in 54.3% of cases. Masking was the second major effect (44.8%) and occurred more frequently when components' pleasantness was significantly different. Synergy occurred in a small number of cases (0.9%) and only for four compounds. The overall odor intensity of the mixture was determined to be equal to the strongest component in most cases (73.9%), while partial addition was observed as the second most frequent effect (21.7%), especially when the components had equal intensity. Overall, this work provides general rules about the outcome to expect when mixing key components of food aromas.Camel milk proteins are an important substrate for bioactive peptides generation. This study investigates in-vitro antidiabetic effect (via inhibition of α-amylase (AA), α-glucosidase (AG) and dipeptidyl peptidase IV (DPP-IV)) of bovine (BC) and camel casein (CC) hydrolysates. Further, effect of simulated gastrointestinal digestion (SGID) on inhibitory potential of generated hydrolysates was also explored. Both BC and CC hydrolysates displayed potent inhibitory properties against AA (IC50 value- 0.58 & 0.59 mg/mL), AG (IC50 value- 1.04 & 0.59 mg/mL) and DPP-IV (IC50 value- 0.62 & 0.66 mg/mL), respectively. Among different peptides identified in BC and CC hydrolysates, it was observed that FLWPEYGAL was predicted to be most potent inhibitory peptide against AA. While LPTGWLM, MFE and GPAHCLL as most active inhibitor of AG and HLPGRG, QNVLPLH and PLMLP were predicted to be active against DPP-IV. Overall, BC and CC hydrolysates can be proposed to be used in different food formulations as functional antidiabetic agents.The raw tea polysaccharides (RLTPS) and the aged tea polysaccharides (ALTPS) from raw and aged Liupao tea were extracted and purified to afford five refined fractions. Component analysis revealed that the crude polysaccharide content from raw Liupao tea increased from 1.83 ± 0.09 g / 100 g to 3.44 ± 0.28 g / 100 g and the molecular weight decreased after fermentation. link3 Structural analysis indicated that the molar ratio of rhamnose, galactose, and galacturonic acid increased in refined ALTPS. All the refined polysaccharides were glycoprotein complexes contained pyranose ring structure. The thermal stability and asymmetry of refined ALTPS were stronger than refined RLTPS. For activities in vitro, ALTPS had better anticoagulant activity and bile acid binding capacity than RLTPS. Although the activities of the refined ALTPS fractions were lower than ALTPS, they were still higher than the refined RLTPS. Fermentation plays an important role in improving the quality and biological activity of dark tea.HMG-CoA reductase (HMGCR) is the rate-limiting enzyme in cholesterol biosynthesis and the target for cholesterol-lowering therapy. Acetaldehyde dehydrogenase 2 (ALDH2) is primarily responsible for detoxifying ethanol-derived acetaldehyde and endogenous lipid aldehydes derived from lipid peroxidation. Epidemiological and Genome Wide Association Studies (GWAS) have linked an inactive ALDH2 rs671 variant, responsible for alcohol flush in nearly 8% world population and 40% of Asians, with cholesterol levels and higher risk of cardiovascular disease (CVD) but the underlying mechanism remains elusive. Here we find that the cholesterol levels in the serum and liver of ALDH2 knockout (AKO) and ALDH2 rs671 knock-in (AKI) mice are significantly increased, consistent with the increase of intermediates in the cholesterol biosynthetic pathways. Mechanistically, mitochondrial ALDH2 translocates to the endoplasmic reticulum to promote the formation of GP78/Insig1/HMGCR complex to increase HMGCR degradation through ubiquitination. Conversely, ALDH2 mutant or ALDH2 deficiency in AKI or AKO mice stabilizes HMGCR, resulting in enhanced cholesterol synthesis, which can be reversed by Lovastatin. Moreover, ALDH2-regulated cholesterol synthesis is linked to the formation of mitochondria-associated endoplasmic reticulum membranes (MAMs). Together, our study has identified that ALDH2 is a novel regulator of cholesterol synthesis, which may play an important role in CVD.
