estrone/inflammation

OBJECTIVE Men with rheumatoid arthritis (RA) have a higher than normal frequency of low testosterone levels, but not much is known about other sex hormones. We investigated serum levels of estradiol, estrone, and the adrenal androgen dehydroepiandrosterone (DHEAS) in men with RA and evaluated the

BACKGROUND Standard risk factors do not adequately capture cardiovascular risk in postmenopausal women. We sought to determine the associations between levels of sex steroids and levels of inflammatory markers in postmenopausal women. METHODS We analyzed baseline data from a subset of postmenopausal

In most studies showing cardio- and vasculoprotective effects of estrogens, 17beta-estradiol was used and little information on possible effects of different estrogen metabolites is yet available. We investigated whether particular estrogen metabolites are effective in counteracting inflammatory

The biological mechanisms underlying the relationship between mammographic density and breast cancer risk are unknown. Our objective was to examine the association between mammographic density and circulating factors that are putative breast cancer intermediate endpoints. Biologic data from a

It has been claimed that hyperestrogenism occurs in hypertrophic osteoarthropathy (HOA), but not in simple clubbing. However, one of our patients had simple clubbing and hyperestrogenism. We therefore measured estrogens, androgens, sex hormone-binding globulin (SHBG), and gonadotropins in five

OBJECTIVE Human amnion-derived cells have been used as in vitro models to test the release of inflammatory mediators, such as arachidonic acid (AA) and prostaglandin E(2) (PGE(2)). We compared estrogen metabolites for their ability to induce AA release, to influence PGE(2) production and to interact

Hydroxysteroid (17-beta) dehydrogenase type 1 (HSD17B1) converts low-active estrogen estrone to highly active estradiol. Estradiol is necessary for normal postpubertal mammary gland development; however, elevated estradiol levels increase mammary tumorigenesis. To investigate the significance of the

In this study, an ASE (Accelerated Solvent extraction)-SPE (Solid Phase Extraction)-GC/MS(SIM) method for the simultaneous determination of five non-steroidal anti-inflammatory drugs (NSAIDs: ibuprofen (IBU), paracetamol (PAR), diclofenac (DIC), naproxen (NAP) and ketoprofen (KET)) and three natural

OBJECTIVE Hormone therapy has been shown to reduce markers of vascular inflammation in . C-reactive protein (CRP), a marker of generalized inflammation, is raised by oral estradiol therapy (ET). It is not known how sex hormone concentrations relate to the markers of inflammation in postmenopausal

OBJECTIVE Tibolone is often taken concurrently with soy. Tibolone, soy and equol-producing capacity each affect vascular health, whereas their concomitant effects are unknown. We studied the effects of soy on sex steroids and vascular inflammation markers in long-term tibolone

To investigate the relationships between blood levels of leptin or adiponectin and lifestyle habits, hormones, and inflammatory markers, we measured parameters of alcohol intake, smoking, physical activity, and blood levels of leptin, adiponectin, testosterone, estrone, estradiol, cortisol,

Background: Intraprostatic inflammation is an emerging prostate cancer risk factor. Estrogens are pro-inflammatory while androgens are anti-inflammatory. Thus, we investigated whether serum sex steroid hormone concentrations are associated with intraprostatic

OBJECTIVE Studies suggest that regular use of nonsteroidal anti-inflammatory drugs (NSAIDs) may lower oestrogen levels in women. However, no large, population-based studies have assessed NSAID/hormone associations in men. Our objective was to examine the association between use of prescription and
