Disadvantageous hybridization favors the evolution of prezygotic isolating behaviors, generating a geographic pattern of interspecific mate discrimination where members of different species drawn from sympatric populations exhibit stronger preference for members of their own species than do individuals drawn from allopatric populations. Geographic shifts in species' boundaries can relax local s...

in pakistan besides pesticide contamination from agricultural field, the manufacturing industriesare also contributing relatively high quantities of toxic pesticides into the environment. these pesticides maybe toxic, mutagenic or carginogenic and may be bioaccumulated or biomagnified by the biota. because ofpersistent nature of pesticides, its removal from environmental system become difficult...

Samples from the kidney of 100 diseased fish with signs of haemorrhagic septicemia and 50 samples from outlet water of fish farms were taken aseptically and cultured. In the laboratory, 75 colonies of gram-negative bacteria were biochemically diagnosed as motile aeromonads in our Bacteriology Laboratory Unit using API 20E rapid identification system. The genotype identification using specific p...

How do observers detect the presence of objects or features in visual images? Stochastic stimuli (for example, white noise) have become popular choices for providing a linear characterization of early sensory mechanisms. A recent paper by Neri and Heeger takes this type of methodology a step further, and succeeds in isolating and characterizing non-linear mechanisms responsible for the detectio...

This study was conducted to determine how the isolation method of the porcine preantral follicles influenced the following follicular growth in vitro. Mechanical and enzymatical isolations were used for retrieving the follicles from prepubertal porcine ovaries, and in vitro-growth of the follicles and the expression of folliculogenesis-related genes were subsequently monitored. The enzymatic re...

four halotolerant fungal isolates originating from the saltwater lake urmia in iran were selected during a screening program for salt resistance and α-amylase activity. the isolates were identified based on sequencing the its region and a part of the β-tubulin gene, as penicillium chrysogenum (isolate u1; cbs 132820), fusarium incarnatum (isolate u2; cbs 132821), and penicillium polonicum (isol...

INTRODUCTION Knowledge of the composition of protein complexes provides key insights into their functions. Immunoaffinity purification provides an effective means for isolating protein complexes and elucidating their composition. Immunoisolation is achieved with antibodies directed either specifically against the proteins of interest or against tags that are coupled to the proteins of interest....
