Pituitary natriuretic peptide signalling via guanylyl cyclase-B (GC-B) receptors in GH3 somatolactotrophs is regulated by protein phosphatase activity but not receptor internalisation

Thompson I , Waltho A , Lambertucci J , Wheeler-Jones C , Fowkes R

Current therapeutics target cGMP in treating erectile dysfunction and other cardiovascular disorders. In the endocrine system, cGMP mediates the vast majority of biological effects of the natriuretic peptides (ANP, BNP and CNP) acting via their specific guanylyl cyclases receptors (GC-A and GC-B). There are severe endocrine consequences for mice and humans exhibiting mutations to GC-B receptors, including achondroplasia, growth hormone deficiency and female infertility. Despit...

The relationship between daytime, nighttime and total heart rate with albumin and protein excretion in newly diagnosed type 2 diabetic patients

Afsar B

Introduction: Autonomic nervous system dysfunction has been widely observed in patients with type 2 diabetes. Twenty-four hour ambulatory heart rate measurements (AHRM) have been found to associate with autonomic dysfunction in patient with type 2 diabetes. Since albumin excretion is also related with autonomic dysfunction; in the current study, we analyzed whether 24-h AHRM were related with 24 h urinary albumin excretion (UAE) and urinary protein excretion (UPE) in newly dia...

The relationship Between Self-Reported Nocturnal Sleep Duration, Daytime Sleepiness and 24-hour urinary Albumin and Protein Excretion in Newly Diagnosed Type 2 Diabetic Patients

Afsar B

Aim: Few studies demonstrated that self-reported nocturnal sleep duration (NSD) were related with urinary protein excretion. However no previous study has specifically addressed the relationship between 24-hour urinary albumin excretion (UAE) and 24-hour urinary protein excretion (UPE) in newly diagnosed type 2 diabetic patients.Methods: All patients underwent history taking, physical examination, blood pressure (BP) measurement, 12 lead electrocardiogra...

The synergistic impact of apolipoprotein B/ A-1 and lipoprotein (a) on coronary artery calcification

Ahn Chul Woo , Choi Arim , Kim Jung Hye , Park Kahui , Lee Sang Bae , Kim Yusik , Nam Ji Sun , Kang Shinae , Park Jong Suk

Objective: Apolipoprotein B/Apolipoprotein A-1 ratio (Apo B/Apo A-1) and lipoprotein (a) (Lp(a)) are known to be associated with atherosclerotic vascular disease. We investigated the influence of Apo B/Apo A-1 and Lp(a) on coronary artery calcification (CAC) among healthy Korean adults.Methods: A total of 1081 participants underwent cardiac computed tomography in health promotion center were enrolled. Anthropometric profiles and multiple cardiovascular r...

The role of B cells in immune cell activation in polycystic ovary syndrome

Ascani Angelo , Torstensson Sara , Risal Sanjiv , Lu Haojiang , Teschl Sabrina , Eriksson Gustaw , Li Congru , Menezes Joana , Sandor Katalin , Svensson Camilla , Stradner Martin , Obermayer-Pietsch Barbara , Stener-Victorin Elisabet

Objective: Age-associated double negative (DN) B memory cells lacking surface expression of CD27 and immunoglobulin D (IgD) are associated with proinflammatory characteristics and higher disease activity in autoimmune diseases. We first characterized B cells phenotypes in women with and without polycystic ovary syndrome (PCOS). We then took an in vivo approach, transferring purified IgG extracted from serum of hyperandrogenic women with PCOS to mice to establish wheth...

CD27-IgD- memory B cells studied in polycystic ovary syndrome

Ascani Angelo , Gumpold Roswitha , Borzan Valentin , Flieszer Elisabeth , Weber Jennifer , Prietl Barbara , Helmut Stradner Martin , Obermayer-Pietsch Barbara

Background: Age-associated double negative (DN) B memory cells lacking surface expression of CD27 and IgD have been associated with proinflammatory characteristics, higher disease activity in autoimmune diseases and disease-specific autoantibodies. We studied the distribution of DN B cells in Polycystic Ovary Syndrome (PCOS), their surface markers and cytokine production.Methods: CD19+ cell subpopulations on the basis of IgD and CD27 expression were phen...

Functional analysis of cardiac orexin receptors: preferential activation by OR-B

Chen J , Karteris E , Rodrigo G , Stanfield P , Ng A , Randeva HS

The family of G-protein coupled receptors (GPCRs) are amongst the best-described regulators of cardiovascular pathophysiology. In rodents, intracerebroventricular administration of orexins increases mean arterial pressure and heart rate. However, important peripheral actions of orexins and their cognate receptors is now increasingly of interest.In this study we demonstrated that both receptors are present across the rat heart, at mRNA and protein level. ...

The presence of B-RAF V600E and K601E mutations in our Ligurian population

Eleonora Monti , Lorenzo Mortara , Simonetta Zupo , Gianluca Ansaldo , Mauro Truni , Francesco Minuto , Massimo Giusti

Introduction: Differentiated thyroid carcinoma (DTC) is the most common endocrine neoplasm and its rate it’s constantly increasing. Papillary thyroid carcinoma (PTC) represents 87% of all DTC and its incidence is raising at 89%. The thyroid carcinoma preoperative diagnosis consists in fine-needle ago aspiration (FNAB). However in the diagnostic cytology there actually is a ‘grey zone’, the ‘follicular lesion of indeterminate significant or suspicious for fo...

Microarray profile of CD19+B cells from Graves’ disease patients reveals potential molecular mechanisms associated with the proliferation of B cell signaling

Jiang Xuechao , Wang Yonghui , Yang Qian , He Leqi , Li Xiaoying , Wang Wei , Liu Jun , Zha Bingbing

Background: Graves’ disease (GD) is a common autoimmune disorder characterized by the production of autoantibodies targeting the thyroid, leading to hypothyroidism. It is widely accepted that B lymphocytes play a significant role in GD as they are the source of autoantibodies (TRAb) against the thyroid-stimulating hormone receptor (TSHR). Previously, we reported that B cells infiltrate the thyroid tissue of GD patients, and in this study we observed that the percentage of...

Inhibin B and AMH are NOT predictors of serum testosterone in young men after cancer

Greenfield DM , Walters SJ , Ross RJM , Coleman RE , Hancock BW , Snowden JA , Ledger WL

Background: In men inhibin B is correlated with sperm count, concentration and testicular volume. Anti-müllerian hormone (AMH) is significantly positively correlated with inhibin B and significantly negatively correlated with FSH. Raised FSH is a traditional marker of infertility. Young male cancer patients treated with gonadotoxic agents are at high risk of hypogonadism (HG). The relationship between inhibin B and AMH with serum total testosterone is unclear.<p class...
