Habituation is a term commonly used to explain a decrement in response intensity to a repeated stimulus or set of stimuli. In the stress literature, hormonal habituation is often used to describe a situation where an individual has learned to perceive a repeated stressor as innocuous, and thus the intensity of the release of hormonal stress mediators reduces over time. Consequently, a habituate...

AIMS To categorise the immunostaining heterogeneity of androgen receptors in metastatic carcinoma of the prostate using a pattern oriented approach and to correlate the results with response to hormonal treatment. METHODS Paraffin wax embedded tumour sections from 85 patients with metastatic carcinoma of the prostate were processed for immunocytochemistry and stained for the androgen receptor...

BACKGROUND The multinational CHOICE (Contraceptive Health Research Of Informed Choice Experience) study evaluated the effects of structured counseling on women's contraceptive decisions, their reasons for making those decisions, and their perceptions of combined hormonal contraceptive (CHC) methods in eleven countries. The aim of this paper to present data from the 1,802 women participating in ...

 Gingiva is a common region of inflammatory and reactive lesions. Systemic conditions, including hormonal imbalance in pregnant women, may cause exaggerated response to irritations such as calculus or infection. Therefore, more accurate assessment is necessary to achieve the best decision making in the differential diagnosis and treatment of these patients. In this paper, we present a rea...

OBJECTIVE Hormonal therapy is an important component of first line of treatment for breast cancer. Response to hormonal therapy is influenced by the progesterone receptor (PR)-status of breast cancer patients. However as an early effect, exposure to progesterone decreases expression of PR in breast cancer cells. An understanding of the mechanism underlying down-regulation of PR could help impro...

 Background: Tissue injuries may provoke neuro-hormonal response which in turn may lead to release of inflammatory cytokines. We hypothesize that block of afferent sensory pathways by infiltration of 0.5% bupivacaine in the scalp may decrease neuro-hormonal response in the neurosurgical patient. Methods: After obtaining informed consent, forty ASA physical statuses I, II, or III patients betwee...
