AI Article Synopsis
Article Abstract
Unselected surgical specimens from 118 cancerous breasts of female patients were studied by histochemistry for the presence of cellular estrogen (ER) and progesterone (PR) receptors. The receptor tracers used were 17 beta-estradiol-6-carboxymethyl-oxim-bovine serum albumin - fluorescein isothiocyanate and 11 alpha-hydroxyprogesterone-hemisuccinate-bovine serum albumin-tetramethylrodamine isothiocyanate conjugate (Fluoro-CepTM). Out of 118 carcinomas 77 (67%) proved to be positive in the ER and 79 (66%) in the PR test. The histochemical results were compared with the results of the biochemical assay in 70 cases. A positive correlation was found in 57 cases.

Hormones control normal breast development and function. They also impinge on breast cancer (BC) development and disease progression in direct and indirect ways. The major ovarian hormones, estrogens and progesterone, have long been established as key regulators of mammary gland development in rodents and linked to human disease.

Triple-negative breast cancer (TNBC) is an aggressive form of breast cancer defined by the lack of three key receptors: estrogen, progesterone, and HER2. This lack of receptors makes TNBC difficult to treat with hormone therapy or drugs, and so it is characterised by a poor prognosis compared to other kinds of breast cancer. This study explores photoactive Poly(lactic-co-glycolic acid) (PLGA) nanoparticles as a potential therapeutic strategy for TNBC.

Women may be challenged to maintain thermoregulation due to hormonal changes associated with the menstrual cycle. The purpose of this study was to assess the effect of the menstrual cycle phase on core temperature, hydration status, and perceived exertion while exercising under uncompensable heat gain. Eleven eumenorrheic women (24.

In the present study, we aimed to investigate intratumoral karyotype diversity as well as the estrogen/progesterone effect on the cytogenetic profile of uterine leiomyomas (ULs). A total of 15 UL samples obtained from 15 patients were cultured in the media supplemented with estrogen and/or progesterone and without adding hormones. Conventional cytogenetic analysis of culture samples revealed clonal chromosomal abnormalities in 11 out of 15 ULs.

Uterine infections reduce ruminant reproductive efficiency. Reproductive dysfunction caused by infusion of Gram-negative bacteria is characterized by the failure of embryo implantation and reduced conception rates. Lipopolysaccharide (LPS), a major component of the outer membrane of Gram-negative bacteria, is highly abortogenic.
