The intake of saturated fat and cholesterol that comes from food digested in the intestine resulting in free fatty acids, triglycerides, phospholipids, and cholesterol. Triglyceride levels increased can be caused by presence of impaired lipoprotein lipase (LPL) enzyme activity. LPL activity can be increased by flavonoid in plant, like Melinjo peel. The purpose of this study is to measure LPL enzyme activity before and after being given extract of Melinjo peel treatment. This research use true experimental, with study design of pretest posttest control group design. Hypercholesterolemic diet given to rats by oral gavage as much as 1,8 grams for 14 days. Melinjo peel extract were given by oral gavage for 14 days after the hypercholesterolemic diet is given. Statistical analysis used Paired Sample T-Test to compare lipoprotein lipase activity before and after treatment. Then, used MANOVA (Multivariate Analyses of Variance) to see the difference of lipoprotein lipase activity in each group after treatment.Based on statistical analysis showed that there were differences of lipoprotein lipase activity in the hypercholesterolemic diet group, HD+54.15, HD+108.30, and HD+216.60 before and after treatment significant (p. < 0.05). The activity of lipoprotein lipase in the normal diet group compared with the hypercholesterolemic and HD+216.60 group showed a significant difference (p. < 0.05). Melinjo peel extract can increased activity of lipoprotein lipase enzym after treatment, those can be due to the flavonoid in Melinjo peel extract.

Wheat (Triticum aestivum. L) grain size is considered to be one of the main criteria of yield constituents by wheat breeders. In order to detect phenotypic diversity and relationship between thousand kernel weight, a collection of 204 landraces from different parts of Pakistan was planted across two years (2012-2014). High throughput method based on seed imaging was used to measure the kernel size and shape. The correlation analysis revealed significant positive correlation between thousand kernel weight (TKW) with perimeter of vertical (PV), thickness (T), area of vertical (AV), area of horizontal (AH), perimeter of horizontal (PH), width (W) and Length (L). Bioplot showed that accessions with high seed shape parameters have higher TKW. By taking TKW as a dependent variable multiple regression analysis was performed. Regression summary indicated that 31% of the variations in TKW are explained by the independent variables. It was shown that grain thickness, length and width are most important for predicting TKW. Based on image analysis this study provides useful information about the relationship between TKW, kernel size and shape in Pakistani wheat landraces that may help to improve grain weight in a breeding program.

ABSTRACT: The giant African snail Achatina fulica was introduced in Brazil and since then has become an important pest, because of its resistance to abiotic conditions, hermaphroditism, polyphagia, and absence of natural predators. This study aims to evaluate the control of A. fulica in lettuce, in Alagoas, Brazil. Bioassays for the determination of lethal dose and lethal time to adults of A. fulica and the egg mortality were performed in the laboratory by applying commercial synthetic products, commercial and non-commercial alcoholic botanical extracts on mollusk adults. Additionally, the protein concentration, lipase activity and enzyme acetylcholinesterase (AChE), and butyrylcholinesterase (BuChE), in the stomach, intestine, nervous ganglion and liver were determined. The alcoholic extract of Capsicum frutescens caused higher mortality of A. fulica, and the alcoholic extract of C. frutescens and Piper tuberculatum oil can prevent the hatching of A. fulica. The lipase activity was present and in greater quantities in tissues, stomach, intestine, liver and ganglia of A. fulica, before and after exposure of the alcoholic extract of C. frutescens. The enzymatic activity of BuChE was present in the ganglia and liver of A. fulica, prior to exposure of the alcoholic extract of C. frutescens. The enzymatic activity of AChE was present only in the ganglion and absent in liver of A. fulica, prior to exposure of the alcoholic extract of C. frutescens. The concentration of 10% of the alcoholic extract of C. frutescens caused 84% mortality of adult A. fulica in lettuce in field conditions.

Abstract Background: Buckwheat deteriorates easily during storage, resulting loss of nutrients, rancidity flavor and poor consumer acceptability. Superheated steam (SS) was used to inactivate lipase of common buckwheat grains in this study, in order to retard lipid hydrolytic rancidity and maintain lipid nutrition of common buckwheat.Methods: Buckwheat grains were treated with SS at 110-200°C, for 0-7 min and SS treatment parameters were optimized by moisture content and lipase activity. The changes in free fatty acid (FFA) and lipase activity of SS-treated and untreated buckwheat during 12 weeks storage at 4°C, 25°C and 50°C were determined. Meanwhile, the effects of SS treatment on fatty acid compositions and lipidomics profile of buckwheat before and after storage were also evaluated. Moreover, the associations of hydrolytic rancidity with lipase activity and lipidomics profile were analyzed.Results: SS processing at 170 °C for 5 min was proved to be an effective method for buckwheat stabilization. Better stabilities based on lower FFA accumulation and lipase activity were observed in SS-treated buckwheat samples during storage. Meanwhile, SS could suppress oxidation of unsaturated fatty acids (UFA) in buckwheat, significantly retard the increase of saturated fatty acids (SFA) and the decrease of polyunsaturated fatty acids (PUFA) during storage. Moreover, the lipidomics profile results indicated that SS processing could retard the increased hydrolysis and oxidation of sulfoquinovosyl diacylglycerol (SQDG), phosphatidylethanolamine (PE), phosphatidylserine (PS) and lysophosphatidic acid (LPA) during storage.Conclusion: Thus, SS processing could effectively inactivate lipase, suppress UFA oxidation, change glycerolipids (GLs) and glycerophospholipids (GPs) subclass metabolism, and consequently retard hydrolytic rancidity and lipid nutrition loss of buckwheat during storage. This work was first time to demonstrate the application of SS processing for the effective quality control of buckwheat during storage.
