Psoriasis is characterized by uncontrolled proliferation and poor differentiation. Sirtuin1 (SIRT1) a class III deacetylase, crucial for differentiation in normal keratinocytes, is reduced in psoriasis. Down regulated SIRT1 levels may contribute to poor differentiation in psoriasis. In addition, the levels of early differentiation factors Keratin1 (K1) and Keratin10 (K10) are depleted in psoria...

Since the prohibition of tributyltin (TBT)-based antifouling paints in 2008, the development of environmentally compatible and commercially realizable alternatives is a crucial issue. Cost effective fabrication of antifouling paints with desired physical and biocompatible features is simultaneously required and recent developments in the direction of inorganic nanomaterials could play a major r...

A 27 year old female with Graves' disease presented with fever, exertional dyspnea and polyarthralgia. Erythema nodosum had occured three months earlier. The patient declared irregular use of propylthiouracil (PTU) for the last 8 months. Neutropenia and microscopic hematuria developed in the second week of admission. Chest X-ray showed inhomogenous pulmonary opacities, left pleural effusion and...

AIMS Endothelial dysfunction is an initial and vascular smooth muscle cell (VSMC) apoptosis, a later step of atherosclerosis. Hypothyroidism accelerates atherosclerosis. However, the early events responsible for this pro-atherosclerotic effect are unclear. METHODS AND RESULTS Rats were resistant to induction of atherosclerosis by high cholesterol diet alone, but became susceptible in hypothyr...

Phenoloxidases (POs) are a family of enzymes including tyrosinases, catecholases and laccases, which play an important role in immune defence mechanisms in various invertebrates. The aim of this study was to thoroughly identify the PO-like activity present in the hemolymph of the Pacific oyster Crassostrea gigas, by using different substrates (i.e. dopamine and p-phenylenediamine, PPD) and diff...

objective(s): the aim of this study was to evaluate the effect of subacute administration of propylthiouracil (ptu) on gentamicin (gm)-induced nephrotoxicity in male rats.   materials and methods: male wistar rats were divided into 4 experimental groups as follow: (1) control group: isotonic saline (1 ml/kg, ip. for 18 d), (2) gm group: 100 mg/kg, ip for 8 d, (3) ptu group: ptu (10 mg/kg, ip fo...

Liver is the main organ which can metabolize many drugs or chemical agents. Toxic events developed by drugs are one of the most common causes of liver damage. Toxic hepatitis can be encountered in different clinical situations, such as acute hepatitis, fulminant hepatitis chronic hepatitis or cirrhosis. We aimed to report a case of asymptomatic toxic hepatitis in a patient taking propylthiourac...

The aim of the present study was to evaluate the effect of lactating 6-propyl-2thiouracil (PTU) on the interactions between the thyroid-axis and prooxidant/antioxidant markers in neonates. PTU was administered to female rats in drinking water (0.1% w/v) from birth to lactation day (LD) 30. The administration gave rise to a highly significant decrease in serum thyroxine (T4) and triiodothyronine...

CONTEXT Methimazole (MMI) and propylthiouracil (PTU) are widely used as antithyroid drugs (ATDs) for the treatment of Graves' disease. Both MMI and PTU reduce thyroid hormone levels by several mechanisms, including inhibition of thyroid hormone synthesis and secretion. In addition, PTU decreases 5'-deiodination of T(4) in peripheral tissues. ATDs may also interfere with T(3) binding to nuclear ...
