IntroductionCardiovascular disease, which may be structural or ischaemic, is the major cause of morbidity and mortality for women with Turner Syndrome (TS). This study investigated arterial augmentation index (AI%) and pulse wave velocity (PWV) as measures of arterial stiffness in adults with TS. A more positive AI% and greater PWV indicate increased arterial stiffness.Method66 women with TS and 8 normal wome...

OBJECTIVE: To determine the characteristics of the QOL impairment observed in GHD survivors of cancer (group 1), and response to GH replacement in comparison with GHD patients with primary pituitary pathology (non-secreting pituitary adenoma or prolactinoma; group 2).METHODS: Patients were considered for GH replacement on the basis of biochemically established severe GHD and subjectively poor QOL noted at interview. QOL was studied at baseline, and at ea...

An 82-year-old male was referred to the breast clinic with a four month history of painful right gynaecomastia (GM), without nipple discharge. A 4 cm plaque of tender, soft tissue was palpable. Physical examination and external genitalia were normal. There was no relevant drug history. Prolactin, Testosterone (T), CXR, Ultrasound and FNA of the breast were normal. LH 13.0 IU (1.5-10.0) and FSH 18.1 IU (1.5-10.0) were raised. FT3 was raised at 7.3 pmol/L (3.5-5.5) with TSH supp...

There is now substantial evidence to suggest that the early life environment can have a permanent effect on adult physiology. Recently we have shown that early postnatal glucocorticoid (GC) exposure produces alterations in midbrain dopaminergic cell number in the adult rat, in a gender-specific manner (McArthur et al., Brit. Neurosci. Assoc. Abstr. 2003;17:27). Since the protein annexin 1 (ANXA1) mediates some aspects of the effects of GCs within the immune system and the hypo...

Introduction:Steroid hormones exert numerous effects through their action on genomic receptors but little is known about the rapid effects mediated via membrane-bound proteins. Analyses in several vertebrate species indicate that three groups (alpha or A, beta or B, and gamma) of membrane progestin receptors (mPR) exist and have distinct tissue distributions.Objective:The aims of this study were to establish ...

The IGF-I receptor (IGF-IR) growth/survival pathways are engaged in crosstalk with pathways induced by cell-cell interactions. Different elements of the IGF-IR signalling system also affect the phosphorylation status of molecules involved in the regulation of cadherin-mediated cell-cell adhesion, such as catenins. In addition, the IGF-IR has been shown to co-precipitate with cell adhesion complexes.In this study, the crosstalk between IGF signalling and ...
