Second thoracic mammary glands of immature BALB/c female mice were stimulated to pregnancy-like lobuloalveolar (LA) development aftr 6 days of incubation in a corticosteroid-free step I culture medium containing insulin, prolactin, estradiol, progesterone, and growth hormone. A low basal level (0.0009%) of casein mRNA (mRNAcsn) sequences was detectable in the LA glands by a specific cDNA probe....

This study involves in vitro androgenesis of Zea mays L. via anther culture. In the first experiment, three embryo induction media were tested in ETH-M82 genotype of maize. The results showed that the embryo structures were established 2 to 3 weeks after culturing the anthers. The effect of induction medium was signifi­cant for embryo frequencies. The obtained results confirm that the induction...

a crd experiment was conducted to study three different soybean meals on experimental qualitative properties, digestibility of protein and performance in broiler chickens for a 42 day period. a total of 195 day-old ross 308 male broiler chickens were randomly distributed to 3 dietary treatments with five replicates of 13 chicks each. to measure digestibility of protein, thirty 15-day-old ross 3...

BACKGROUND Laboratory diagnosis of tuberculosis has undergone a rapid change during last few years and a number of techniques for culture as well as molecular diagnosis have been used with their respective advantages and disadvantages. Sporadic studies have also reported the isolation of M. tuberculosis on standard blood agar (BA), which at one time was not considered as a suitable medium for m...

background: many studies reported that follicle size has an essential role in developmental potential of oocytes. also, the brilliant cresyl blue (bcb) test is one of the most important criteria in selection of more competent oocytes. objective: selection of developmentally competent bovine oocytes. materials and methods: a total of 1730 bovine cumulus oocyte complexes (cocs) were recovered fro...

These media appear to be distinctly different with respect to their physical and chemical properties. Yet the Separation between them becomes more blurred as information recorded in one medium can be copied readily onto another. Conventional examples are the miaofilming of newspapers, or the photocopying of whole fragile books. Modem scanning techniques allow any form of information whether pic...
