Effect of firm attributes on return on asset of listed manufacturing companies in Nigeria

The profitability of manufacturing companies does not only play the role of improving the market value of that specific company but also leads to the overall growth of the whole sector which translate to improvement on profit level that could be attributable to characteristics possessed by firms. It is on this the study examines the effect of firm attributes on the return on assets of listed companies in Nigeria for a period of five years. The population and sample size of this study comprises of all the 41 listed manufacturing companies in the Nigerian Stock Exchange as at 31 December, 2016. The result of random effect regression provides evidence that all firm attributes apart from operating expenses and firm size had a negative and significant effect on return on asset. Based on this result, the study recommends that listed manufacturing firms should reduce firm size and operating expenses so as to increase the return on assets of their firms and short term cash should not be channeled to fund capital asset.peer-reviewe

Study of Digoxin as inhibitor of the in vivo effects of acetyl glyceryl ether phosphorycholine (AGEPC) in mice

Acetyl glyceryl ether phosphorylcholine (AGEPC) and the cardiac glycoside digoxin were administered intravenously through the tail vein into ether-anesthetized SWR mice (two months old). The administered doses were 0.18 nmol AGEPC/ g.b.w. (a lethal one) and 75 or 125 ng digoxin/b.w. Digoxin ameliorates the effects of the lethal dose of AGEPC showing maximum activity when given 5 or 10 min after AGEPC administration to female and male animals respectively. Digoxin shows also a protective action towards the effects of AGEPC and maximum activity appears when it is given 10 min before AGEPC administration. In agreement with the picture of increased survival in digoxin pretreated animals, are our findings on life prolongation of mice which finally die from AGEPC, the amelioration of the expected fall in blood platelet counts after AGEPC administration as well as the improved performance of the animals in a series of physical tests. © 1988
