Lattice Boltzmann modelling regarding interfacial bulk exchange within a multiphase technique.
Protein digestibility of pepeta flour was 58.9% higher than that of cooked rice for variety TXD306, and 73.8% higher for Lawama. Differential scanning calorimetry indicated that starch of processed immature rice was completely gelatinized whereas its susceptibility to digestion in vitro was slightly lower than for cooked rice, possibly due to the higher cellular integrity retained after processing. These results demonstrate that pepeta-type processing improves the nutritional properties of rice and its potential use as a snack or ingredient in cereal-based formulas.The oil processing industry generates significant quantities of lemon basil seed residue which is not currently used to any significant extent. BMS-387032 clinical trial However, this by-product has important potential as a source of bioactive peptides which may play a role as ingredients in functional foods. This study therefore sought to optimize the preparation techniques used to obtain the necessary protein hydrolysate from de-fatted lemon basil seeds (DLBS), and subsequently to examine the ACE inhibitory capabilities of the resulting hydrolysate. Response Surface Methodology (RSM) was used for the hydrolysis of DLBS by Alcalase®, with observation of the resulting ACE inhibitory activity and degree of hydrolysis (DH). The optimum conditions were 55 °C and 103 minutes with a ratio of enzyme to substrate of 7.0% w/v. The hydrolysate was fractionated by ultrafiltration and purified through RP-HPLC. The results reveal that the F2 sub-fraction demonstrated the highest ACE inhibitory activity. The amino acid sequence of this peak was identified by mass spectrometry as LGRNLPPI and GPAGPAGL with a molecular weight of 879.06 and 639.347 Dalton, respectively. These peptides were classified as non-toxic and bitter peptides. For the synthesized version of these peptides, the ACE inhibitory activity values, measured by IC50, were 0.124 ± 0.02 mM and 0.013 ± 0.001 mM, respectively. Analysis of the Lineweaver-Burk plot confirmed that these peptides served as non-competitive ones. The study of molecular docking showed that the ACE inhibitory behavior of both purified peptides was mainly due to the interactions of the hydrogen bonds between the peptides and ACE. It is therefore suggested that DLBS may be a useful raw material allowing the production of antihypertensive peptides which can offer therapeutic and commercial benefits as an ingredient in functional foods.Here we report novel bispidine-based coordination polymers (CPs) 2·TCM, 3·TCM, 3·NB, 5·TCM and 5·TCM·NB, of compostition [Mn(Cl)2(L2)2·(TCM)2], [Mn(Cl)2(L3)2·(TCM)5], [Mn(Cl)2(L3)2·(NB)8], [Mn(Cl)2(L5)2·(TCM)4], [Mn(Cl)2(L5)2·(TCM)2·(NB)2], respectively (NB = nitrobenzene; TCM = chloroform). link2 They were obtained starting from novel bispidine ligands L2 (dimethyl 7-isopropyl-3-methyl-9-oxo-2,4-di(pyridin-4-yl)-3,7-diazabicyclo[3.3.1]nonane-1,5-dicarboxylate), L3 (dimethyl 7-(cyclohexylmethyl)-3-methyl-9-oxo-2,4-di(pyridin-4-yl)-3,7-diazabicyclo[3.3.1]nonane-1,5-dicarboxylate) and L5 (dimethyl 7-(4-(dimethylamino)benzyl)-3-methyl-9-oxo-2,4-di(pyridin-4-yl)-3,7-diazabicyclo[3.3.1]nonane-1,5-dicarboxylate), The novel CPs were characterized by single crystal X-ray diffraction (SC-XRD), powder X-ray diffraction (PXRD) and thermal analyses (TGA). We describe their structural and dynamic properties in terms of solvent exchange and adsorption processes, and we outline the general trends observed on the basis of a total of 16 X-ray structures (4 new) and 21 microcrystalline powder phases (10 new), which have been obtained so far for CPs by coordination of ligands L1-L5, having different substitution at the N7 position. This large set of CPs comprises monosolvated, bisolvated and desolvated species, and it shows a good demonstration of how small differences in the functionalization of the organic ligand can have a strong impact on the resulting structural and dynamic properties of this class of 1D CPs.A pulsed Nd  YAG laser ablation of FeS in water and ethanol produces FeS-derived colloidal nanoparticles that absorb onto immersed porous ceramic substrates and create solar-light photocatalytic surfaces. The stability, size distribution and zeta potential of the nanoparticles were assessed by dynamic light scattering. Raman, UV-Vis and XP spectroscopy and electron microscopy reveal that the sol nanoparticles have their outmost layer composed of ferrous and ferric sulphates and those produced in water are made of high-pressure orthorhombic FeS, cubic magnetite Fe3O4 and tetragonal maghemite γ-Fe2O3, while those formed in ethanol contain hexagonal FeS and cubic magnetite Fe3O4. Both colloids absorb solar light and their adsorption to porous ceramic surfaces creates functionalized ceramic surfaces that induce methylene blue degradation by daylight. The laser induced process thus offers an easy and efficient way for the functionalization of porous surfaces by photocatalytic nanoparticles that avoids aggregation in the liquid phase. The formation of an orthorhombic high-pressure FeS phase stable under ambient conditions is the first example of high-pressure structures produced by laser ablation in liquid without the assistance of an electric field.The results of randomized controlled trials (RCTs) investigating supplemental vitamin D on aminotransferases and cardio-metabolic risk factors in subjects with non-alcoholic fatty liver disease (NAFLD) have been inconsistent. The present study aimed to quantitatively evaluate whether supplementation with vitamin D has beneficial effects in treatment of NAFLD. A systematical literature search was performed with Cochrane Library, PubMed, Scopus databases and Web of Science up to June 2020. The mean changes in alanine aminotransferase (ALT), aspartate aminotransferase (AST), fasting glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and triglyceride (TAG) were calculated as standard mean difference (SMD) using a random-effects model. Pre-specified subgroup and univariate meta-regression analyses were performed to identify the sources of heterogeneity. Ten trials with a total of 544 NAFLD subjects were included for data synthesis. The summary estimates indicated that supplemental vitamin D significantly reduced the levels of serum/plasma fasting glucose (-0.22; 95%CI -0.39, -0.04), insulin (-0.68; 95%CI -1.22, -0.14) and HOMA-IR (-1.32; 95%CI -2.30, -0.34), and marginally reduced the ALT (-0.18; 95%CI -0.39, 0.04) and TAG (-10.38; 95%CI -21.09, 0.34) levels. However, the pooled effect did not support that supplemental vitamin D was beneficial for concentrations of AST, TC, HDL-C and LDL-C. The present study provides substantial evidence that supplemental vitamin D has favorable effects on glycemic control and insulin sensitivity in NAFLD patients. Vitamin D could be as an adjuvant pharmacotherapy of NAFLD.Long-term intake of a high-fat diet seriously affects the health of pregnant women and leads to increased levels of inflammation in the mammary gland. Therefore, to further explore the effect of a high-fat diet on mammary gland development and the tight junction (TJ) during pregnancy, we placed mice into two groups a high-fat diet group and a control group. We detected the expression of proteins related to fat synthesis in the mammary gland by western blotting. The results showed that a high-fat diet could lead to an increase in fat synthesis in the mammary gland. Then, the inflammatory levels and acinar cell morphology in the mammary gland were detected by ELISA and H&E staining. We also measured the levels of MAPK and NF-κB signal pathway-related proteins by western blotting. The results showed that a high-fat diet activated the MAPK and NF-κB signaling pathways and promoted the expression of inflammatory factors. Finally, the development of the mammary gland and the integrity of the TJ were determined by immunohistochemistry, immunofluorescence and western blotting. The results showed that a high-fat diet inhibited the development of the mammary gland and the expression of tight junction proteins (TJs). Our study showed that a high-fat diet could promote the expression of inflammatory factors by activating the MAPK and NF-κB signaling pathways and could reshape the microenvironment through extramammary inflammation. Finally, a high-fat diet inhibited the development of the mammary gland during pregnancy and destroyed the integrity of the TJ.Carbonyl sulfide (COS) and carbon disulfide (CS2) are important atmospheric gases that are formed from organic sulfur precursors present in natural waters when exposed to sunlight. However, it remains unclear how specific water constituents, such as dissolved organic matter (DOM), affect COS and CS2 formation. To better understand the role of DOM, irradiation experiments were conducted in O2-free synthetic waters containing four different DOM isolates, acquired from freshwater to open ocean sources, and the sulfur-based amino acid, cysteine (CYS). link3 CYS is a known natural precursor of COS and CS2. Results indicated that COS formation did not vary strongly with DOM type, although small impacts were observed on the kinetic patterns. COS formation also increased with increasing CYS concentration but decreased with increasing DOM concentration. Quenching experiments indicated that ˙OH was not involved in the rate-limiting step of COS formation, whereas excited triplet states of DOM (3CDOM*) were plausibly involved, although the quenching agents used to remove 3CDOM* may have reacted with the CYS-derived intermediates as well. CS2 was not formed under any of the experimental conditions. Overall, DOM-containing synthetic waters had a limited to no effect towards forming COS and CS2, especially when compared to the higher concentrations formed in sunlit natural waters, as examined previously. The reasons behind this limited effect need to be explored further but may be due to the additional water quality constituents present in these natural waters. The findings of this study imply that multiple variables beyond DOM govern COS and CS2 photoproduction when moving from freshwaters to open ocean waters.The effects of precooked-refined sorghum flour consumption on antioxidant status, lipid profile, and colonic and bone health were evaluated. Twenty-four male Wistar rats were fed with control diet (C), or red or white precooked-refined sorghum based diets (SD) for 60 days. The intake of SD was lower than that of C, but the efficiency of all diets was similar. Rats fed with SD showed lower feces excretion, cecal pH and enzyme activities (β-glucosidase, β-glucuronidase and mucinase) than C. White SD improved intestinal architecture, cell proliferation and apoptosis, upregulated ZO1 and occludin tight junction proteins and stimulated goblet cell differentiation, enhancing the integrity of the mucosa barrier in both proximal and distal colonic mucosa in a better way than red SD. Consumption of SD significantly decreased serum triglyceride levels compared with the C diet. The mineral content of the right femur was not different among diets. The liver enzyme activities (superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase) did not show differences among diets.
