Within-herd phenotypic and genetic trend lines for milk yield in Holstein-Friesian dairy cows
A total of 937 pedigree, breeding and performance records of 567 Friesian cows at the Livestock Experiment Station Bhunikey Dist. Kasur (Pakistan) spanning the years 1982-2001 were analyzed using Best Linear Unbiased Predictions procedure. Individual animal models were fitted to total milk yield from all lactations to estimate breeding values by Restricted Maximum Likelihood methodology. Milk yield and lactation length...

Antilipidemic effect of chitosan against experimentally induced myocardial infarction in rats
Myocardial infarction is a major public health concern and the leading cause of death all over the world. A better understanding of the processes involved in myocardial infarction has stimulated the search for new drugs, which could limit the myocardial injury. In the present study, an attempt has been made to examine the preventive effects of chitosan, a marine polysaccharide, on isoprenaline-induced myocardial...
