Investigating the reactivity of small nucleophilic scaffolds is a strategic approach for the design of new catalysts aiming at effective detoxification processes of organophosphorus compounds. The drug methimazole (MMZ) is an interesting candidate featuring two non-equivalent nucleophilic centers. Herein, phosphoryl transfer reactions mediated by MMZ were assessed by means of spectrophotometric kinetic studies, mass spectrometry (MS) analyses, and density functional theory (DFT) calculations using the multi-electrophilic compound O,O-diethyl 2,4-dinitrophenyl phosphate (DEDNPP).

Materials And Methods: Twenty-four uniradicular bovine teeth were selected. The crowns were sectioned at the cementoenamel junction, and the root canals were treated.
Objective: To evaluate the impact of sexual function (SF) in the quality of life (QoL) of women with premature ovarian insufficiency (POI).
Methods: Case-control study in which 80 women with POI were evaluated using estrogen plus progestogen therapy, compared with 80 women matched by age (±2 years) and presenting preserved gonadal function. Sexual function was evaluated using the Female Sexual Function Index (FSFI), and the QoL was evaluated using the World Health Organization's (WHO) QoL assessment instrument (WHOQoL-BREF).
Purpose: To evaluate some microbiological aspects of the vaginal flora and the vaginal trophism of women with premature ovarian failure (POF) in use of oral hormone therapy.
Methods: A cross-sectional study with 36 women with POF under the age of 40 years using oral hormonal therapy. They were age matched with 36 women with normal gonadal function (control group).
Introduction: Women with premature ovarian failure (POF) often manifest complaints involving different aspects of sexual function (SF), regardless of using hormone therapy. SF involves a complex interaction between physical, psychological, and sociocultural aspects. There are doubts about the impact of different complaints on the global context of SF of women with POF.

Women with premature ovarian failure (POF) represent a challenge, since they require prolonged HT. Little is known about the impact of prolonged HT use on these women's breasts.

Objective: To evaluate the breast density of women with POF using estrogen-progestin therapy compared with normally menstruating women.
Methods: A cross-sectional study was performed in 31 women with POF using conjugated equine estrogens and medroxyprogesterone acetate and a control group of 31 normally menstruating women, paired by age.
Background: Benign metastasizing leiomyoma (BML) of the lung is a rare manifestation of metastasis from a uterine myoma, in which its benign characteristics are maintained. The majority of cases are asymptomatic.
Cases: Case 1 responded to the classic treatment of oophorectomy, after which an improvement in symptoms was achieved.
