Are saliva and bile sources of oxalate secretion into the human gastrointestinal tract?
Physiological Reports, Volume 14, Issue 8, April 2026.Abstract Elevated urine oxalate (hyperoxaluria) is a risk factor for kidney stones. Normally eliminated by the kidneys, oxalate originates from endogenous metabolism and dietary absorption but secretion into the intestine remains an open question. We considered saliva and bile as two potential sources.

Colorimetric Analysis of Norethindrone, Norethindrone Acetate, and Norgestrel in Oral Contraceptives
Journal of AOAC INTERNATIONAL, 1970 Abstract A colorimetric method, based on reaction with blue tetrazolium, has been devised for the analysis of norethindrone, norethindrone acetate, and norgestrel. The technique is selective for these progestins, showing no interference from the estrogens ethinyl estradiol and mestranol, commonly found in oral contraceptives.

Physiological Reports, Volume 14, Issue 8, April 2026.The effect of oral contraceptives (OCs) on muscle repair is unknown. Using electrical pulse stimulation to simulate damage in C2C12 myoblasts treated with four OC generations (MPA, LNG, DSG, DRP combined with ethinyl estradiol), we assessed proliferation, differentiation, migration, creatine kinase, myogenic proteins, and hormone receptor protein ...
