Biopharmaceuticals are complex molecules and can show variation between production batches. Physicochemical tests and biological activity measurements contribute complementary data to the characterisation of these products.As part of a project to correlate physicochemical and bioassay data, under the Department of Trade and Industry’s Measurements for Biotechnology programme, we have developed a simple, robust cellbased bioassay protocol for interfe...

Background: Adrenocortical carcinoma in childhood is a rare tumour which accounts for about 0.2% of all paediatric malignancies. Affected children usually present with virilization, cushingoid features, and/or mineralocorticoid excess. We present a boy with adrenal carcinoma presented with virilization and unusually suppressed cortisol at initial presentation.Case report: A two-year-old boy presented with pubic hair, acne, and increased penile growth wit...

Introduction: Primary hyperparathyroidism (PHPT) patients who undergo parathyroidectomy can develop isolated intact parathormone (iPTH) elevation with normal calcemia. Common causes are: renal insufficiency (RI), vitamin D deficit and hypomagnesemia.Aim: To identify clinical factors associated with iPTH elevation in patients submitted to surgery treatment.Methods: The medical records of patients admitted into Santo António&#14...

We report an 18-year-old boy referred to our outpatient clinic at 8 years and 11 months of age with a history of early-onset childhood hiperphagia, infantile central hipotonia and lethargy, mild mental retardation and emotional instability. His height was 125 cm, height SDS = -1 (target height = 169,5 cm, SDS = -0,78) and he weighted 40 Kg (BMI = 25,6;WFH =164%). He had small hands and feet, fat face with prominent forehead, bitemporal narrowing, triangular upper lip, microgna...

Aims/hypothesis: Several data have shown the association between diabetes type 2 (DM2) and transcription factor 7-like 2 (TCF7L2) gene polymorphisms, in several and different ethnical populations. Although the pathophysiology is not completely clear, it seems that beta and alpha cell functions are abnormal. Up to these days there is no clinical data showing association between TCF7L2 gene polymorphism allele rs7903146 T and beta cell insulin and C-peptide contents in DM2 patie...
