197 results about "Progestogen" patented technology

Progestogens, also sometimes written progestagens or gestagens, are a class of steroid hormones that bind to and activate the progesterone receptor (PR). Progesterone is the major and most important progestogen in the body. The progestogens are named for their function in maintaining pregnancy (i.e., progestational), although they are also present at other phases of the estrous and menstrual cycles.

Extended cycle multiphasic oral contraceptive method

A multiphasic method of contraception comprising the steps of sequentially administering to a female of child bearing age a Phase I composition containing a progestogen in an amount equivalent to about 0.3 to about 1.5 mg norethindrone acetate and an estrogen in an amount equivalent to about 5 to about 15 mcg of ethinyl estradiol for about 7 to about 14 days; a Phase II composition containing a progestogen in an amount equivalent to about 0.3 to about 1.5 mg of norethindrone acetate and an estrogen in an amount equivalent to about 10 to about 25 mcg of ethinyl estradiol for about 14 to about 22 days; a Phase III composition containing a progestogen in an amount equivalent to about 0.3 to about 1.5 mg of norethindrone acetate and an estrogen in an amount equivalent to about 15 to about 35 mcg of ethinyl estradiol for about 20 to about 31 days; and an optional Phase IV composition containing (i) an estrogen in an amount equivalent to about 5 to about 20 mcg of ethinyl estradiol, or (ii) a placebo or a non-steroidal component, or (iii) a combination of (i) and (ii), for about 2 to about 8 days. The ethinyl estradiol equivalent amount of estrogen in each of the successive Phases II and III is at least 5 mcg greater than the ethinyl estradiol equivalent amount of estrogen in the immediately-preceding phase.

Serum-free preservation liquid for umbilical cord mesenchymal stem cells and application of serum-free preservation liquid

The invention provides serum-free preservation liquid for umbilical cord mesenchymal stem cells and application of the serum-free preservation liquid. The serum-free preservation liquid comprises normal saline with a NaCl mass fraction of 0.85-0.92%, insulin, estrogen, progestogen, hydrocortisone, sodium selenite, adenosine, N-acetylcysteine and L-glutamine. The insulin, the estrogen and the progestogen are added into the normal saline. Compared with serum preservation liquid, the serum-free preservation liquid and the application have the advantages that material sources capable of generating harm due to toxin with diversified components can be reduced to the greatest extent; the serum-free preservation liquid contains functional components with few components, basal metabolism of the cells can be maintained, and the cells are smooth in performance without huge variation; certain basic active nutrient substances and energy substances can be provided by the components, so that low metabolism level can be kept, the activity of the cells is in a stable state, shape variation or differentiation or the like due to growth and cultivation can be prevented, protection effects can be realized for the cells, the activity and the quality of the transplanted umbilical cord cells can be kept in a long-acting manner, and transplanted cell therapy clinical effects can be improved.
