A 65-year-old woman complained of dyspnea and a productive cough after surgical treatment and irradiation therapy for thymoma. Chest radiography and high-resolution computed tomography showed small nodules in centrilobular lesions in all of both lung fields, but predominantly in the lower fields. In

A patient with diffuse panbronchiolitis (DPB) complicated by malignant thymoma and Sjögren's syndrome with pseudolymphoma is reported. A 58-year-old woman developed productive cough, dyspnea and sicca in the mouth. Laboratory findings on admission indicated a high titer of cold hemagglutinin,

Erythropoietic hypoplasia occurring in the absence of abnormalities in the leukopoietic and thrombocytopoietic series is often defined as "pure red cell aplasia" (PRCA). This condition may appear as an acquired defect of either acute or chronic type, and a congenital form as well. The chronic form

Increased expression of mitochondrial peroxiredoxin-3 (thioredoxin peroxidase-2) protects cancer cells against hypoxia and drug-induced hydrogen peroxide-dependent apoptosis.

Peroxiredoxin-3 (Prdx3) is a mitochondrial member of the antioxidant family of thioredoxin peroxidases that uses mitochondrial thioredoxin-2 (Trx2) as a source of reducing equivalents to scavenge hydrogen peroxide (H(2)O(2)). Low levels of H(2)O(2) produced by the mitochondria regulate physiological

BACKGROUND Hypoxic-ischemic insults to the neonatal brain may cause neurodevelopmental disorders. Vulnerability of different areas of the neural tissue to hypoxic-ischemic stress might be explained by either heterogeneous sensitivity to oxygen or neuroprotective capability. Our understanding of

Bronchopulmonary dysplasia (BPD) is a major cause of morbidity in premature infants receiving oxygen therapy. Currently, sildenafil is being examined clinically to improve pulmonary function in patients with BPD. Based on the pharmacological action of sildenafil, the elevation of cyclic guanosine

HISTORY AND PRESENTATION: A 12 year old, 4.2 kg, domestic long hair, castrated male cat was presented with regurgitation, inability to retract the claws, general weakness, cervical ventroflexion and weight loss. A thymic mass was evident on radiographs. Acetylcholine receptor antibody titer was

Thymoma is a rare epithelial tumor arising from the thymus in the anterior mediastinum. Nearly 50% of patients with thymoma develop myasthenia gravis, which is an indication of a poor long-term prognosis. Here, we identified specific and effective molecular markers for predicting in

18F-fluorodeoxyglucose positron emission tomography/computed tomography and the relationship between fluorodeoxyglucose uptake and the expression of hypoxia-inducible factor-1α, glucose transporter-1 and vascular endothelial growth factor in thymic epithelial tumours.

OBJECTIVE The objective of this study was to evaluate the usefulness of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) and the relationships among the expressions of hypoxia-inducible factor-1α (HIF-1α), glucose transporter-1 (Glut-1) and vascular endothelial

The present report describes the first reported case of microscopic pulmonary tumour embolism (MPTE) from thymic carcinoma. The carcinoma was discovered during an autopsy in a 55-year-old man who had undergone surgery for a pilonidal sinus two weeks before presentation. Pulmonary thromboembolism was

The overall survival of patients with hepatocellular carcinoma (HCC) remains poor, and the molecular mechanisms underlying HCC progression and aggressiveness are unclear. Here, we report that increased expression of p28(GANK) (Gankyrin, PSMD10, or p28) in human HCC predicts poor survival and disease

Thymic epithelial tumors (TETs) comprise several histologies of thymoma and thymic carcinomas (TCs), and TC frequently metastasizes and causes death. We therefore aimed here to identify key molecules closely related to prognosis and their biological roles in high-risk TETs,

A 32-year-old man with myotonic dystrophy underwent a thoracotomy for removal of a mediastinal thymoma. Pre-operative examination revealed features of myotonic dystrophy, the only other abnormality was mild restrictive pulmonary disease. Anaesthesia was induced with thiopentone and maintained with

All patients who are to undergo a thymectomy should be evaluated thoroughly by a neurologist--ideally one with special training and interest in the diagnosis and management of MG. Confirmatory tests to diagnose MG and other potential diseases should be reviewed. The antibody test seems to be most
