The gut microbiome is important for host health and can be influenced by environmental hormonal changes. We studied the interactions between anthropogenic land use, glucocorticoid hormones, bacterial communities in common toads (Bufo bufo). sampled tadpoles from ponds of three habitat types (natural, agricultural, urban ponds), examined composition using amplicon sequencing 16S rRNA gene, measu...

It has been shown that women's preference for masculinity in male faces changes across the menstrual cycle. Preference for masculinity is stronger when conception probability is high than when it is low. These findings have been linked to cyclic fluctuations of hormone levels. The purpose of the present study is to further investigate the link between gonadal steroids (i.e. testosterone, estrad...

BACKGROUND Studies have reported current hormonal contraceptive use is associated with adverse cardiovascular outcomes, including high blood pressure. The aim of this study was to determine the association between past hormonal contraception use and high blood pressure in Australian postmenopausal women. METHODS Women were recruited from the 45 and Up Study, an observational cross-sectional s...

OBJECTIVES Since 2000, the Province of Quebec has experienced a shortage of physicians and a decrease in access to prescription contraceptives. A task-shifting strategy was launched in 2007 to allow trained nurses, in collaboration with community pharmacists, to start healthy women on hormonal contraception for a six-month period without a medical consultation. This study examined the proportio...

The aim of this study was to examine the pattern of attendance of patients requesting Emergency Hormonal Contraception (EHC) at an accident and emergency department before and after a government driven change in legislation, which allowed EHC to be sold over-the-counter by trained pharmacists, to women aged 16 years and above. We employed retrospective comparative study using computer records o...

Toxoplasma gondii is an intracellular parasite responsible for causing toxoplasmosis, a disease that infects approximately one-third of the global population. It crucial to note this can infect both mammals and birds. Furthermore, it be transmitted humans through different transmission routes. Vertical from infected pregnant woman her fetus horizontal via contaminated or raw food drinks are mos...

The estrogen receptor (ER) is implicated in the progression of breast cancer. Despite positive effects of hormonal therapy, initial or acquired resistance to endocrine therapies frequently occurs. Recent studies suggested ERa-coregulator PELP1 and growth factor receptor ErbB2/ HER2 play an essential role in hormonal therapy responsiveness. Src axis couples ERa with HER2 and PELP1, thus represen...

Prolactin (PRL) is mitogenic for lymphocytes in vitro, but the responsiveness of lymphocytes depends on the in vivo hormonal status of the rats from which the cells were obtained. Lymphocytes from ovariectomized (OVX) rats, but not from rats in oestrus or from male rats, respond to prolactin; administration of oestradiol to OVX rats diminishes the response. In order to determine if a correlatio...
