During the stimulation period, a fresh stimulus (piece of filter paper containing 30 μl of male urine) was added to the cage twice a day.
On the day of stimulation, fresh medium was added more than 1 h before exposure to stress in order to ensure the same conditions for each culture.
After 72 hours of co-culture with or without TNF-α or PHA stimulation, fresh supernatant was collected.
For functional testing of TLR-mediated lymphocytic stimulation, fresh PBMCs were incubated for 16 hours with LPS and the T cells were analysed for their intracellular production of perforin.
For estrogen starvation, cells were plated at 40% confluence in steroid-free medium (phenol red-free DMEM medium, with 5% fetal bovine serum pre-treated with dextran-coated charcoal and antibiotics) and maintained for 5 days with replacement of fresh medium before stimulation with 10-8M 17β-estradiol (E2).
Despite the small reduction in fertilization rate, the retrieval of many preovulatory oocytes produced ongoing pregnancy rates per stimulation (fresh- plus frozen-cycle embryo transfers) of 28.3% when six to ten preovulatory oocytes were retrieved and 41.5% when more than ten were retrieved.
Bone-marrow-derived macrophages were differentiated on non-tissue-culture-treated plastic, harvested and replated at a density of 100000 cells/cm per 0.1 ml on tissue culture-treated plastic in fresh medium before stimulation on day 8. RAW264.7 cells were cultured in DMEM containing 10% FBS, 2 mM glutamine and penicillin and streptomycin.
We love novel sensory stimulation.
Most of the previous studies focused on the effect of mixing chelating agents with fresh water in matrix stimulation.
Permeable fractured and altered zones are cooled by the invasion of drilling mud or fresh water during hydraulic stimulation operations.
