Despite the impact of prostate-specific antigen (PSA) testing on the detection and management of prostate cancer, controversy about its usefulness as a marker of disease activity continues. This review, based on a recent roundtable discussion, examines whether PSA measurements can be used rationally in several clinical settings. Following radical prostatectomy and radiation therapy, prediction ...

Ornithine aminotransferase, a mitochondrial matrix enzyme, is expressed constitutively in many mammalian tissues and is subject to complex hormonal and dietary regulation in rat liver and kidney. The kidney enzyme is induced by estrogen and thyroid hormone (3,3',5-triiodo-L-thyronine, T3). We demonstrated previously that the hormonal induction in kidney is the result of an increase in ornithine...

UNLABELLED The purpose of this study was to clarify the characteristic patterns of the thyroid hormonal changes in Graves' disease during the one-year period after 131I therapy considering that few serial hormonal data during this period are available in the literature. METHODS The levels of serum T3, T4 and FT4 before and during one year were plotted as a function of time in 70 therapy cours...

Despite the crucial roles of phytohormones in plant development, comparison of the exact distribution profiles of different hormones within plant meristems has thus far remained scarce. Vascular cambium, a wide lateral meristem with an extensive developmental zonation, provides an optimal system for hormonal and genetic profiling. By taking advantage of this spatial resolution, we show here tha...

Abstract We conduct a laboratory experiment among male participants to investigate whether rewarding schemes that depend on work performance—in particular, tournament incentives—induce more stress than are independent of performance—fixed payment scheme. Stress is measured over the entire course at both hormonal and psychological level. Hormonal responses captured by measuring salivary cortisol...

effects of culture medium containing hormonal compositions on phenotypic and chromosomal variations of sugarbeet cultured tissues were examined. experiments were carried out in different nacl levels. cytological studies were conducted on calli originated from suspension culture. hypocotyl of seven day old seedlings of the two diploid lines were cultured in ms medium containing hormonal composit...

two hundred and fifty day-old broiler chickens were housed in a high altitude farm and divided in two experimental groups (cold-exposed and control). at the age of 3 and 4 d, the cold-exposed chickens were exposed to 15?c for 3 h, while the control birds were reared under normal condition. during the period between 14 and 28 days, both groups of chickens were exposed to a low environmental temp...

BACKGROUND A number of studies have shown over-expression of cox-2 in breast cancer. Also it has been recorded that human breast cancer expresses high level of cox-2 and 12-lipoxygenase which may be beneficial in future therapy plan for those patients. AIMS The present study aims to examine the level of transcripts of cox-2 and 12-lipoxygenase in Egyptian breast cancer patients and to compare...
