Lipoxin A4 (LXA4), an endogenous anti-inflammatory and immunomodulatory mediator studied in many disease states, is recently appreciated as a potentially significant player in the endometrium. This eicosanoid, synthesized from arachidonic acid via the action of lipoxygenase enzymes, is likely
Unopposed estrogens for treating menopausal symptoms were extensively used when epidemiological findings associated them with an increased endometrial cancer risk. Adding progestogens reverse this side effect efficiently but patient, dose, type and especially time during which the progestogen is
CONCLUSIONS
Application of topical estriol ointment is an effective treatment for hereditary hemorrhagic telangiectasia (HHT) epistaxis.
OBJECTIVE
HHT is an autosomal-dominant disease characterized by epistaxis in more than 96% of patients. Management of this major symptom, epistaxis, has not been
A supramolecular solvent (SUPRAS) made up of inverted hexagonal aggregates of decanol was here proposed for the simultaneous microextraction of representative estrogenic disruptors (EDs) [viz. estrone (E1), 17β-estradiol (E2), estriol (E3), 17α-ethinylestradiol (EE2) and bisphenol A (BPA)] in
Placental sulfatase deficiency has been found in four pregnancies (cases 1 to 4) with inappropriately low levels of urinary estriol excretion (less than 1.3 mg. per day near term gestation) associated with healthy neonates. The basis of the diagnosis in these cases was the greatly limited capacities
Ultrasound assisted degradation of estrogen hormones was examined in a batch reactor using a 2 kW (20 kHz) sonication unit. The degradation of estrogens follow a pseudo first order rate kinetics, and the order of degradation is 17alpha-dihydroequilin > equilin >17alpha-ethinyl estradiol
BACKGROUND
Spontaneous recurrent epistaxis is the most common clinical manifestation of hereditary hemorrhagic teleangiectasia (HHT). It occurs in more than 90% of HHT patients and is the most distressing symptom. Nasal teleangiectasias tend to increase with age both in size and number, so epistaxis
To study the changes in steroid concentrations in amniotic fluid (AF) in relation to the initiation of parturition, eleven steroids in AF which included cortisol(F), progesterone (P4), 20 alpha-dihydroprogesterone, free(f-) and conjugated(c-) pregnenolone, DHA, estradiol(E2) and estriol(E3) were
Guaiacol peroxidase (G-Px) was measured in extracts from five sections along the length of human uterus on different days of the menstrual cycle or after menopause. The lower uterine-endocervical region had a significantly higher G-Px content (expressed as enzyme units per g wet tissue) than the
Biological receptors distinguish and bind steroid sex hormones, e.g., androgen-, progestogen-, and estrogen-type hormones, with high selectivity. To date, artificial molecular receptors have been unable to discriminate between these classes of biosubstrates. Here, we report that an artificial
