Meningiomas have often been described as being hormone dependent because of their preponderant incidence in females with clinical manifestation during or after pregnancy. The authors have experienced three cases of meningioma which became symptomatic during pregnancy, after delivery, or during menses. Estrogen receptor protein and progesterone receptor protein of the meningioma tissue were exam...

Renal functions are regulated by steroid sex hormones, but the exhaustive identification of their receptors along the nephron is still lacking. Here, we have localized all known nuclear or membrane-bound sex hormone receptors and some of their activators along the nephron of male and female mice. Almost all receptors are present in male and female kidney, some of them having very restricted loc...

BACKGROUND The aim of this study was to investigate the association between sex and speech-ABR in adults, and its relationship to sex hormone levels. MATERIAL AND METHODS Speech-ABR were elicited with the consonant-vowel syllable (/da/) in a total of 35 adults. Reproductive hormone levels were also measured. RESULTS The transient response of the speech-ABR (waves V, A, and O) in females show a ...

Sex expression in cucumber is influenced by hormonal and environmental factors such as day length and temperature. Increasing female flowers that will develop to fruit is a trick for increasing yield, hence it’s importance. Likewise, it would help breeders through hybridizing process. Ethylene as a plant hormone is known to increase female flowers of most members of Cucurbitaceae family but as ...

Decline in circulating sex steroid hormones accompanies several age-associated pathologies which may influence human healthspan. Mitochondria play important roles in biosynthesis of sex steroid hormones, and these hormones can also regulate mitochondrial function. Understanding the cross talk between mitochondria and sex steroid hormones may provide insights into the pathologies associated with...

BACKGROUND Sex-related differences in the severity of multiple sclerosis (MS) could be influenced by the sex hormones. MATERIALS AND METHODS This cohort (historical) study evaluated the sex hormone levels during menstrual cycle and their correlation with disease severity in MS. RESULT Patients with MS had significantly lower testosterone, dehydroepiandrosterone sulfate and prolactin levels ...
