Menstrual disturbances following COVID-19 vaccination: A probable puzzle about the role of endocrine and immune pathways.

Menstruation is a monthly shedding of the uterine wall, presented by menstrual bleeding in women of reproductive age. Menstruation is regulated by fluctuation of estrogen and progesterone, as well as other endocrine and immune pathways. Many women experienced menstrual disturbances after vaccination against the novel coronavirus in the last two years.

Obesity and iron-deficiency anemia in women of reproductive age in northern Iran.

Background: Obesity and iron deficiency (ID) are two forms of the most usual nutritional disorders worldwide. Some studies have discovered a correlation between ID and obesity although more investigation is required. This study was aimed to determine the association between obesity and ID anemia (IDA) in Iranian childbearing age women.

Effect of crocin on biochemical parameters, oxidative/antioxidative profiles, sperm characteristics and testicular histopathology in streptozotocin-induced diabetic rats.

Objective: Chronic hyperglycemia and overproduction of reactive oxygen species (ROS) are strong predictors of the development of reproductive complications of diabetes. The present study was conducted to determine the effects of crocin on biochemical parameters, oxidative stress, and sperm characteristics as well as testes histopathology in diabetic rats.

Materials And Methods: Twenty-four rats were divided into the four groups as follows: control, untreated diabetic and two crocin (40 and 60 mg/kg/day)-treated diabetic groups.

Comparative evaluation of antimicrobial activity of two root canal sealers: MTA Fillapex and AH 26.

Aim: Even after a complete root canal therapy, reinfection may occur as a result of incomplete seal and activation of residual bacteria. Thus, antimicrobial activity is an important characteristic of root canal sealers. MTA Fillapex is a newly developed MTA-based sealer.
