Although culture of Trichomonas vaginalis is more sensitive than wet mounts in the diagnosis of trichomoniasis, the lack of convenience of culture prevents it from being widely used. To improve the acceptability of diagnosis by culture, a plastic envelope method (PEM) was devised. PEM permits both immediate examination and culture in one self-contained system. The medium consists of dry ingredi...
background: addition of amino acids to the culture medium is beneficial for embryonic development in many species. objective: the objective of this study was to investigate the effects of amino acids on the in vitro maturation and embryonic development of the bovine oocyte. materials and methods: bovine ovaries were collected from a local abattoir and brought into laboratory. cumulus-oocyte com...
Bovine preantral follicles (40-100 microm diameter at collection) were collected from ovaries of slaughtered cows and cultured in vitro with one of the four treatments: follicle stimulating hormone (FSH; 100 ng/ml) alone; FSH plus epidermal growth factor (EGF; 100 ng/ml); FSH plus insulin-transferrin-selenium (ITS; +1%) or FSH plus hypoxanthine (4 mM) in tissue culture medium (TCM 199) suppleme...
most of the systematic studies used in the development of human embryo culture media have been done first on mouse embryos. the general use of nmri outbred mice is a model for toxicology, teratology and pharmacology. nmri mouse embryo exhibit the two-cell block in vitro. the objective of this study was to evaluate and compare the effects of four kinds of culture media on the development of zygo...
During chronological aging of budding yeast cells, the culture medium can become acidified, and this acidification limits cell survival. As a consequence, buffering the culture medium to pH 6 significantly extends chronological life span under standard conditions in synthetic medium. In this study, we assessed whether a similar process occurs during replicative aging of yeast cells. We find ...
Leishmania braziliensis braziliensisíMHOMlBR1751M2903) was grown in Schneider's Drosophila medium. In one set of experiments promastigotes were already adapted to the medium by means of seria1 passages whereas in the second cells were grown in a biphasic medium and transfered to the liquid. Growth was more abundant for culture medium-adapted cells; degenerate cells in small numbers as well as d...
A new liquid culture medium prepared with chemicals that can be obtained economically and commercially was tested in in vitro cultivation of Leishmania promastigotes to obtain a large number of organisms to use in serological studies. The number of Leishmania infantum and Leishmania tropica promastigotes taken from Novy-MacNeal-Nicolle (NNN) medium reached 1 x 10(7)/ml at the end of the 8th day...
