Background: Gamma-Knife Stereotactic Radiosurgery (STRS) is a single highly focused dose of radiotherapy used for intracranial pathologies, including pituitary tumours. At the National Centre for Stereotactic Radiosurgery in Sheffield more than 450 patients undergo STRS per year. The UK experience of this modality of treatment for acromegaly is limited because of the few gamma knife units in operation.Objective: To assess the effectiveness and safety of ...

Hemoglobin A1c (HbA1c) is used for the long-term management of patients with diabetes mellitus (DM). Hemoglobin variants other than HbA1c and e-N-lysine-glycated HbA0 may cause analytical interference in determinations of HbA1c. Hemoglobin J is an abnormal hemoglobin, an alpha globin gene variant and present in various geographic locations. Hemoglobin J (depending on its type) has different characteristics and functions. For example hemoglobin J Capetown (α2 92Gln β2...

Objective: To investigate the results of J – 131 treatments in patients (pts) with autonomous thyroid adenomas in long period of follow up.Material and Methods: We enrolled 68 consecutive pts with Plummer’s disease (50 females, 18 males, mean age 54,7 yrs, range 21 – 79 yrs) for period 2000 – 2020 yrs. 87%(59/68) pts had a unifocal nodule, while 13% (9/68) pts had multifocal toxic autonomous nodules. Pts stopped antithyroid drugs for ...

Autoimmune thyroid diseases (AITD), such as Graves' disease (GD) and autoimmune thyroiditis (AT), cluster within families and within individuals and exhibit a strong female preponderance. The type 1 diabetes Warren Repository was established between 1989 and 1996 and contains 505 families of British white Caucasian origin. Each family consists of both parents and at least two siblings with type 1 diabetes. We have examined the clinical data collected to establish the frequency...

Vasopressin acts through G protein-coupled receptors on the cardiovascular and renal system to induce vasoconstriction and antidiuresis. Vasopressin also has important functions within the CNS influencing cognition, olfaction and a range of complex social interactions and behaviours. In addition, vasopressin has been reported in the mammalian retina and here we investigated the location and expression of vasopressin and vasopressin receptors (V1a, V1b, and V2) in the rat retin...

J J Kopchick, Ohio University, Athens, Ohio, USA. AbstractDr John J Kopchick is an internationally recognized leader in the growth hormone (GH) field. Since 1987, he has held the Milton and Lawrence H Goll Eminent Scholar Professorship in Molecular and Cellular Biology and directs the Growth/Obesity/Diabetes Section of the Edison Biotechnology Institute at Ohio University in Athens, Ohio. He also is Professor in the B...

Oncogenic activation of MAPK in thyroid cells leads to loss of expression of genes required for thyroid hormone biosynthesis, including the sodium iodide transporter (NIS) and thyroid peroxidase (TPO). Tumors with BRAF mutation have lower expression of NIS, explaining in part why BRAF-mutant PTCs are often resistant to RAI therapy. We developed mouse models of thyroid cancer driven by BRAFV600E, and these tumors also lose the ability to concentrate radioiodine, whic...
