goiter/hypoxia

Patients with diffuse toxic goiter showed a distinct reduction of the cytochromoxidase activity in the peripheral blood leucocytes. The degree of reduction of the cytochromoxidase activity in the leucocytes depended on the severity of the clinical course and degree of increase of the thyroid gland.

BACKGROUND In the thyroid, iodine deficiency (ID) induces angiogenesis via a tightly controlled reactive oxygen species (ROS)-hypoxia inducible factor-1 (HIF-1)-vascular endothelial growth factor (VEGF) dependent pathway (ROS-HIF-VEGF). Deficient iodine intake may be associated with increased

A 25-yr-old obese parturient with mild asthma underwent an uneventful spinal anesthetic for primary cesarean delivery. Within 4 h after delivery, the patient twice developed acute shortness of breath, inspiratory stridor, and hypoxemia that required intubation. A battery of blood tests revealed no

The objective of the present study was to elicit opinion from two groups of veterinarians [subject matter experts and non-subject matter experts] about the causes of bovine perinatal mortality and the criteria used to assign such causes. The subject matter experts were selected on the basis of their

BACKGROUND The usefulness of 2-[(18)F]-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography (PET) has been investigated in thymic epithelial tumors. However, little is known about PET imaging of (18)F-FDG in primary non-thymic mediastinal neoplasms. The aim of this study is to explore

Goitrogenesis in Graves' disease (GD) has been attributed to anti-TSH receptor antibody stimulation. Recently, a role for adenosine A2a receptor (A2aR) in goiter formation was reported in the thyroglobulin-A2aR transgenic mice. However, it is unclear whether A2aR is expressed in the thyroid and

Described are rare thyroid lesions which either contain mature adipocytes or consist of lipid-rich follicle cells. Of the former, diffuse lipomatosis and adenolipoma of the thyroid are most likely to be derived from heterotopic islands of fat cells included in the gland during embryogenesis. On the

A response of the heart to hypoxia was studied in experimental thyrotoxicosis and physical exercise in patients with the thyrotoxic goiter. A decrease in the duration of cardiac hyperfunction and acceleration in the suppression of cardiac function in hypoxia were observed in rats with thyrotoxicosis

In thyrocytes, cell polarity is of crucial importance for proper thyroid function. Many intrinsic mechanisms of self-regulation control how the key players involved in thyroid hormone (TH) biosynthesis interact in apical microvilli, so that hazardous biochemical processes may occur without detriment

A thyrotoxic Crisis is an acute or subacute metabolic explosion caused by uncontrolled release of tyronines from the thyroid gland (more frequently a diffuse thyroid gland) following its injury: strumectomy, administration of a therapeutic dose of I131, inflammations, or excessive stimulation

BACKGROUND Vascular endothelial growth factor (VEGF) is involved in tumor angiogenesis and other pathophysiological processes. METHODS We studied the localization of VEGF in human thyroid tissues to clarify its involvement in proliferative processes in a variety of thyroid disorders.

Vascular endothelial growth factor (VEGF) is one of the factors related to angiogenesis of tumors and physiological and pathological proliferative processes. Location of VEGF in human thyroid tissue with various thyroid disorders was studied in order to explore its possible involvement in
