A factorial design was used to analyzethe influenceofSauropus androgynusleaf extract (SALE) and turmeric powder (TP) on fat deposition in broilers fed high-fat diet. The first factor was the source of fat (6% beef fat and 6% palm oil), and the second factor was SALE plus TP [0 g SALE plus 0 g TP (G1), 9 g SALE plus 0.5 g TP (G2), 18 g SALE plus 0.5 g TP (G3), 9 g SALE plus 1 g TP (G4), 18 g SALE plus 1 g TP (G5)]. SALE plus TP affected cholesterol,lauric acid, myristic acid, palmitic acid, stearic acid and eicosapentaenoic acid contents (p<0.01).Fat sources affected fat, cholesterol, lauric acid, myristic acid, palmitic acid, stearic acid and eicosapentaenoic acid (p<0.01). There was a significant interaction between the two factorson fat, cholesterol, lauric acid, palmitic acid, stearic acid, and eicosapentaenoic acid contents. In conclusion, 18 g SALE plus 1 g TP supplementation to high-fat diet resulted in lower stearic acid, but it resulted in higher eicosapentaenoic acid. Supplementation of SALEplus TPto a high-fat diet lowered cholesterol content and changed fatty acidscomposition.

Safflower, were extracted using propanol solvent at different time intervals: 10, 20, and 30 min at a constant temperature of 40°C. The extracts were analyzed by GC/MS technique. The major compounds identified were tetrapentacontane, tetracontane, triacontanol, gamma sitosterol, myristic acid, linoleic acid, stearic acid, palmitic acid, oleic acid, and lauric acid. However, some levels of palmidrol, beta-amyrin, cubenol, and tocopherol were also found in safflower extracts. Most of the volatile compounds were detected between 10–30 min time of extraction. The 30 min time of extraction also showed the maximum content of polyphenols and antioxidants in safflower extracts. Thus, 30 min was suggested as the most suitable time for maximum extraction of bioactive volatiles, antioxidants, and polyphenols from Safflower using propanol solvent.

ABSTRACT After sensing external signals, Proteus mirabilis undergoes a multicellular behavior called swarming which is coordinately regulated with the expression of virulence factors. Here we report that exogenously added fatty acids could act as signals to regulate swarming in P. mirabilis. Specifically, while oleic acid enhanced swarming, some saturated fatty acids, such as lauric acid, myristic acid, palmitic acid, and stearic acid, inhibited swarming. We also found that expression of hemolysin, which has been shown to be coordinately regulated with swarming, was also inhibited by the above saturated fatty acids. Previously we identified a gene, rsbA, which may encode a histidine-containing phosphotransmitter of the bacterial two-component signaling system and act as a repressor of swarming and virulence factor expression in P. mirabilis. We found that while myristic acid, lauric acid, and palmitic acid exerted their inhibitory effect on swarming and hemolysin expression through an RsbA-dependent pathway, the inhibition by stearic acid was mediated through an RsbA-independent pathway. Biofilm formation and extracellular polysaccharide (EPS) production play an important role in P. mirabilis infection. We found that RsbA may act as a positive regulator of biofilm formation and EPS production. Myristic acid was found to slightly stimulate biofilm formation and EPS production, and this stimulation was mediated through an RsbA-dependent pathway. Together, these data suggest that fatty acids may act as environmental cues to regulate swarming and virulence in P. mirabilis and that RsbA may play an important role in this process.

SummaryThe effects of the isocaloric replacement of part of the dietary concentrate mixture by 5% lauric acid (99% pure) or by 10% of myristic (95% pure), palmitic (96% pure) or stearic (94% pure) on the yield and composition of milk fat was investigated in 2 feeding experiments with a total of 10 cows in mid-lactation. The concentrate mixtures were given with a high-roughage diet that supplied 9·1 or 7·7 kg hay/day in expts 1 and 2, respectively.In expt 1 the inclusion of myristic acid in the diet decreased the yields of milk and solids-not-fat (SNF), but increased the percentage of fat in the milk without altering the fat yield. When stearic or palmitic acid was included in the diet there was an increase in milk fat yield; palmitic acid caused the greater increase. In expt 2 the inclusion of lauric acid in the diet did not appear to affect the yields of milk or SNF but it caused large reductions in the percentage of fat in the milk and in the yield of fat.In expt 1 the inclusion of myristic acid increased the yields and percentages of 14:0, 14:1 and 16:1 in the milk fat and decreased the yields and percentages of the short-chain fatty acids (4:0–8:0), 16:0, 18:0 and 18:1. When palmitic acid was included in the diet there were increases in the yields and percentages of 16:0 and 16:1 in the milk fat and decreases in the yields and percentages of 10:0, 12:0, 14:0, 18:0 and 18:1. The inclusion of stearic acid in the diet increased the yields and percentages of 18:0 and 18:1 in the milk fat and decreased the yields and percentages of 12:0 and 16:0. In expt 2 the inclusion of lauric acid in the diet increased the yield and percentage of 12:0, and in 1 cow the content of 14:0 in the milk fat; there were reductions in the yields and percentages of all the other fatty acids in the milk fat. There was no evidence of any marked elongation of the carbon chains of 12:0 and 14:0 in the mammary gland to form 16:0 or 18:0.In expt 1 the incorporation of myristic acid in the diet decreased the concentration of total steam-volatile fatty acids in rumen liquor. The inclusion of either myristic, palmitic or stearic acid in the diet had little effect on the relative proportions of the individual volatile acids in the rumen liquor. In expt 2 the addition of lauric acid to the diet reduced the acetic acid:propionic acid ratio in the rumen liquor.

A chemically defined medium (CC-494) was used to study the lipid utilization of two flower spiroplasmas (Spiroplasma florkola and SR-3) and honeybee spiroplasma (AS-576). All three spiroplasmas reached comparable growth yields when lauric acid, myristic acid, or stearic acid replaced palmitic acid; palmitoleic acid, linoleic acid, or linolenic acid replaced oleic acid; and campesterol, ergosterol, β-sitosterol, or stigmasterol replaced cholesterol. None of the spiroplasmas grew when 5A-cholestane replaced cholesterol.

Regulate Lipid Metabolism

A high-fat diet often leads to excessive fat deposition and adversely affects the organism. However, the mechanism of liver fat deposition induced by high fat is still unclear. Therefore, this study aimed at acetyl-CoA carboxylase (ACC) to explore the mechanism of excessive liver deposition induced by high fat. In the present study, the ORF of ACC1 and ACC2 were cloned and characterized. Meanwhile, the mRNA and protein of ACC1 and ACC2 were increased in liver fed with a high-fat diet (HFD) or in hepatocytes incubated with oleic acid (OA). The phosphorylation of ACC was also decreased in hepatocytes incubated with OA. Moreover, AICAR dramatically improved the phosphorylation of ACC, and OA significantly inhibited the phosphorylation of the AMPK/ACC pathway. Further experiments showed that OA increased global O-GlcNAcylation and agonist of O-GlcNAcylation significantly inhibited the phosphorylation of AMPK and ACC. Importantly, the disorder of lipid metabolism caused by HFD or OA could be rescued by treating CP-640186, the dual inhibitor of ACC1 and ACC2. These observations suggested that high fat may activate O-GlcNAcylation and affect the AMPK/ACC pathway to regulate lipid synthesis, and also emphasized the importance of the role of ACC in lipid homeostasis.

Abstract In this paper, we provide a new approach for the anionic modification and functional application of nanocellulose. The nanocrystalline cellulose (NCC) is prepared from microcrystalline cellulose (MCC) and modified by fatty acids (lauric acid, palmitic acid and stearic acid). Ammonium ceric sulfate or hydrogen peroxide/ferrous sulfate being used as an initiator, three kinds of modified nanocrystalline cellulose (MNCC) can be synthesized at low temperature. The terminology for these MNCC is L-MNCC (NCC modified by lauric acid), P-MNCC (NCC modified by palmitic acid) and S-MNCC (NCC modified by stearic acid). Compared with those existing synthesized methods, the reaction condition is mild, and the modified products show strong stability. It can be seen from morphological structure analysis and reaction conditions analysis of MNCC that the original structure of cellulose is changed slightly. And the optimal conditions for preparing MNCC are obtained. The best yields of L-MNCC, P-MNCC and S-MNCC are 54.2 %, 20.9 % and 14.5 %, respectively.
