No full textA ketogenic diet, regardless of fish oil content, does not affect glucose homeostasis or muscle insulin response in rats.
No full textKetogenic diets (KDs) are very high in fat and low in carbohydrates. Evidence supports that KDs improve glucose metabolism in humans and rodents that are obese and/or insulin resistant. Conversely, findings in healthy rodents suggest that KDs may impair glucose homeostasis. Additionally, most experimental KDs are composed of saturated and monounsaturated fatty acids, with almost no omega-3 long-chain polyunsaturated fatty acids (n-3 LCPUFA). Evidence supports a beneficial role for the n-3 LCPUFA eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on glucose homeostasis in the context of a metabolic challenge. To our knowledge, no study has examined whether the inclusion of EPA and DHA affects the impact of a KD on glucose homeostasis. The objective of this study was to examine the impact of a KD on whole-body glucose tolerance and skeletal muscle insulin response in rats, and to determine if increasing the n-3 LCPUFA content in a KD with menhaden oil could improve metabolic outcomes. Male Sprague Dawley rats were pair-fed one of a low-fat diet, high-fat diet, KD, or a KD supplemented with menhaden oil (KDn-3) for 8 weeks. No significant differences in whole-body glucose tolerance, skeletal muscle insulin signaling, or skeletal muscle insulin-stimulated glucose uptake were detected between the dietary groups. Our findings suggest that KD feeding, with or without supplementation of n-3 LCPUFA, does not affect whole-body glucose homeostasis or skeletal muscle insulin response under pair-feeding conditions

Farmer preferences for groundnut traits and varieties in West Africa: Cases of Mali, Niger and Nigeria.Working Paper Series no. 27
No full textParticipatory varietal selection trials were implemented in Mali, Niger and Nigeria and were
used to assess farmers’ preferences for plant and seed traits of selected groundnut varieties.
Using a panel of farmers in every country, plant and seed traits were assessed and found
to be statistically associated with the varieties tested. Ordered probit models were used to
identify plant and seed traits liked by panelists. Color of the leaves, maturity (short cycle),
number of pods, pod size, constriction, pod yield, pod filling and taste were the important
attributes explaining farmers ranking for varieties in Mali. In Niger, the color of the leaves,
the number of pods per plant, pod filling, pod beak, and pod yield were the most important
traits sought by farmers. In Nigeria, plant vigor, plant maturity, plant type, number of pods
per plant, pod size, haulm yield and pod yield were the preferred traits. These traits should
be used to identify varieties (from large germplasm collections) most likely to be adopted
by farmers. Varieties with traits sought by farmers should be promoted and used to build
sustainable seed supply systems. Attributes such as color of leaves, pod reticulation and pod
beak tend to be overlooked and should be included in future breeding programs

Exotherm Curves: A Method for Obtaining Reproducible Curing Parameters for Radiation Polymerization of Vinyl-Divinyl Comonomers
No full textPolymerization parameters, suitable for both monitoring and comparative studies on catalytic and radiation polymerization of MMA/divinyl comonomers, are readily derived from time/temperature exotherm records. By geometric solution of exotherm curves Gel Effect Point (GEP), polymerization rate coefficients in Activation (PRCI) and Acceleration (PRCII), and total dose (D) became available for kinetic studies. Individual components of the exotherm curve, such as reciprocal of time required to attain maximum on the exotherm curve, provide information on the overall rate of cure (ORC). Reciprocal of the time required to reach GEP characterizes the efficiency of cross-linking agents to cause onset of the gel effect phenomena in comonomer systems.Repeated measurements and statistical analyses of such data, derived from exotherms, show good reproducibility and a high degree of reliability, especially with systems exhibiting rather sharp maxima on the exotherm curve
The Mediating Role of Psychological Empowerment on The Relationship Between Person-organization Fit and Innovative Work Behavior (A case Study at Sekolah Kristen Makedonia)
No full textInnovative Work Behavior is a very important part of a company. This study aims to determine the mediating role of Psychological Empowerment on the relationship between Person-Organizational Fit and Innovative Work Behavior (a case study at Sekolah Kristen Makedonia). The results of this study found that Person-Organization Fit had a positive and significant effect on the Psychological Empowerment, Person-Organization Fit has no significant effect on the Innovative Work Behavior (IWB). Psychological Empowerment has a positive and significant effect on the Innovative Work Behavio, the role of the Psychological Empowerment variable (Z) mediate variable that mediates the influence between the Person-Organization Fit variable (X) and the Innovative Work Behavior Variable (Y).Afsar, B., Badir, Y. and Khan, M.M.
