Introduction: Our group has a bank of human primary thyroid cultures (BANTTIC) obtained from patients. All are individual cultures specifically genotyped and phenotyped. We believe of great interest the search for biomarkers in these cultures using differential proteomic analysis.We have applied differential proteomics using 2D-PAGE coupled to MALDI-TOF-TOF-MS. We have compared benign pathologies (normal thyroid and Pendred’s syndrome) and different...

Introduction and objectives: Multiple surgeries are associated with many complications in the local recurrence of papillary thyroid carcinoma. Our objective is to evaluate the efficiency of the enolization in the recurrent metastatic cervical lymph nodes in patients with limited nodal disease.Material and methods: We studied 13 patients (six males and seven females) with a mean age of 43±14.4 years with papillary thyroid carcinoma intervened (total ...

Introduction: Cyclic Cushing’s syndrome (CCS) is extremely rare. It’s defined by periodic hypercortisolism with at least three proven peaks and two drops in cortisol secretion.Case report: A 35-year-old woman was reffered for evaluation of endogenous hypercortisolism after a diagnosis of central serous coriorethinopathy. Initially she had mild symptoms. Urinary free cortisol (UFC) was 2.881 μg/24 h; ACTH 17.45 pg/ml and night salivary cort...

Introduction: Mechanism underlying glucose-mediated development and progression of diabetic complication are incompletely understood. Atrial natriuretic peptide (ANP) is a hormone released by atrial myocytes in response to acute and chronic extracellular volume expansion. Moderate hyperglycaemia (>400 mg/dl) in diabetic rats is associated with an elevation in circulating ANP levels and in GFR (glomerular filtration rate), (1) and play a role in the development of microalbu...

Introduction: Cross-sex hormone treatment (CHT) in male-to-female (M2F) transsexuals affects the hemostatic balance, with the emergence of a prothrombotic state with the use of certain estrogen (oral ethinyl estradiol vs 17β estradiol). Testosterone administration to F2M transsexuals had an antithrombotic effect. In female-to-male in (F2M) transsexuals administration of testosterone seems to carry a mild antithrombotic effect.Objective: To quantify ...

The Liver X Receptor (LXR) agonists have been shown to influence the development of hyperlipidemia and atherosclerosis in mouse models. It has also been demonstrated that some LXR agonists can cause hepatic steatosis in experimental animals. GH is also known to regulate hepatic metabolism and absence of the hepatic GH receptors leads to hepatic steatosis. In this study we analyzed whether actions of LXR agonists could involve interference with GH signaling. We showed that LXR ...

Case presentation: A 84 year-old male without family history of thyroid disease was referred to our clinic by his cardiologist, diagnosed as having primary hypothyroidism, characterized by persistent elevated TSH without response to L-thyroxine over the course of a year. Co-morbidities included arterial hypertension, auricular fibrillation (AF) and glucose intolerance, treated with propafenone, clopidogrel, enalapril, and digoxine. On physical examination, he pr...

Introduction: Reference ranges for classifying a patient as hyper-, normo- and hypothyroidism vary from one laboratory to another, because the techniques used, regional factors (race, iodine..), but there is also the variables of age and sex of the patient are not taken. Article Thyroid Volume 21, Number 1, 2011, 5–11 Boucai et al, published equations to adjust the normal range in terms of these variables. Evaluate these equations and see if there are significant changes ...

Up to now there are few studies about differential proteomics in thyroid. Our group has developed a method for standard human primary thyroid culture maintaining the phenotype through passages. Thus, we believe of great interest the search for biomarkers in these cultures by 2D-PAGE coupled to MALDI-TOF/TOF-MS.Aims: i) To standardize the conditions for sample extraction and controls. ii) To compare and identify the differential proteomic pattern between ...

Background: Vitamin D deficiency is common worldwide. No homogenous reference values have yet been established and no studies of values have been done in Spain involving a large number of participants.Objective: To study the population concentrations of vitamin D in a representative sample of the Spanish population.Subjects/methods: The study involved two cohorts from Spain, the Asturias Study and the Pizarra Study, which are two p...
