breast feeding has a great impact on the infant morbidity and mortality. according to pakistan demographic and health survey (pdhs) infant mortality rate is 78 deaths per 1,000 live births. world health organization recommends that exclusive breast feeding for six months can decrease infant mortality rate by one-third. the objective of the study was to find out how the mode of delivery had impa...

The mechanisms by which nonrandom mating affects selected populations are not completely understood and remain a subject of scientific debate in the development of tractable predictors of population characteristics. The main objective of this study was to provide a predictive model for the genetic variance and covariance among mates for traits subjected to directional selection in populations w...

Where divergent ecological adaptation also leads to assortative mating between populations, speciation is facilitated. We have extensively studied two examples from among the Lepidoptera, in which ecologically selected traits have pleiotropic effects on the mating system. Based on our understanding of mating behaviour and pleiotropy derived from these empirical examples, we here review pleiotro...

background and objectives:  hawthorn is a forest fruit tree which is grown in the temperate regions around the world. this plant is known as the most traditional herbal remedy for heart failure and cardiovascular disease in worldwide. this study has been conducted to investigate the genetic variability and classify hawthorn genotypes based on quantitative and qualitative characteristics of leaf...

Two experiments explored the possibility that specific health risks observed among young women may be influenced by attractiveness-enhancement goals associated with mating. Study 1 (n = 257) demonstrated that priming women with intersexual courtship and intrasexual competition increased their willingness to go tanning and take dangerous diet pills. Study 2 (n = 148) conceptually replicated thes...

Isozyme phenotypes were determined for 101 strains of Gibberella fujikuroi and 2 strains of Gibberella nygamai that represent seven biological species (mating populations) isolated from a variety of plant hosts in dispersed geographic locations. Fourteen enzymes were resolved in one or more of three buffer systems. Two of the enzymes, arylesterase and acid phosphatase, were polymorphic within t...

sera from ninety one patients clinically suspected to extra intestinal amoebiasis (ex-am) were collected and examined for presence of anti entamoeba histolytica (e.h) antibody. the tests were indirect immunofluorescence antibody, (ifa or iif), gel diffusion (gd) and counter immuno electrophoresis (ciep). thirty one patients (34%) had anti e.h. antibody titres of >1:80. among them eight patients...
