The patient was a 19-year-old woman who was diagnosed with patent ductus arteriosus complicating Eisenmenger syndrome at a previous medical institution. She was referred to our hospital and arranged for lung transplantation. She developed hemoptysis after the introduction of i.v. epoprostenol, which was administered as a bridging treatment while the patient awaited lung transplantation. She continued to suffer from recurrent hemoptysis, even after switching from i.v. epoprostenol to i.v. treprostinil. Angiography of the systemic and pulmonary arteries revealed the vessel responsible for the recurrent hemoptysis and pulmonary artery embolization was successfully performed...

BACKGROUND: Polymorphisms in genes encoding proteins of the leptin-melanocortin pathway have been associated with obesity. The involvement of these polymorphisms with changes in body mass index (BMI) and anthropometric measures could also imply a contribution to the risk of metabolic syndrome (MetS) and metabolic alterations. We evaluated the relationship of leptin-melanocortin system polymorphisms with obesity, MetS, and other metabolic alterations in Southern Chilean individuals. METHODS: Two-hundred individuals were grouped as normoweight (BMI 18...

Bilateral pulmonary artery banding (PAB) has emerged to be an attractive option as an initial procedure for the treatment of hypoplastic left heart syndrome (HLHS), and some centers report excellent survival. However, its usage is variable among institutions and its true efficacy is unknown due to reporting biases. We aimed to describe the results of bilateral PAB use, preoperative risk factors, and long-term outcomes compared with primary Norwood procedure, using a national database. Infants who underwent bilateral PAB or Norwood procedure as an initial palliation for HLHS between January 2008 and December 2012 listed in the Japan Congenital Cardiovascular Surgery Database (JCCVSD) were included...

Immusorba TR (IM-TR) and PH (IM-PH) were developed as immunoadsorbents from nonbiological materials as affinity ligands for removal of pathogenic substances. The immunoadsorbents in IM-TR and IM-PH are immobilized on a polyvinyl alcohol gel with tryptophan and phenylalanine, respectively, as a ligand. IM-TR is mainly clinically applied to autoimmune neurological diseases such as myasthenia gravis, Guillain-Barré syndrome, and multiple sclerosis. IM-PH is also applied to neurological diseases but mainly to rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus...

Recent studies report the involvement of intra-ovarian factors, such as inflammation and oxidative stress, in the pathophysiology of polycystic ovary syndrome (PCOS), the most common endocrine disorder of reproductive age women. Endoplasmic reticulum (ER) stress is a local factor that affects various cellular events during a broad spectrum of physiological and pathological conditions. It may also be an important determinant of pro-fibrotic remodeling during tissue fibrosis. In the present study, we showed that ER stress was activated in granulosa cells of PCOS patients as well as in a well-established PCOS mouse model...

Objective Supraventricular arrhythmias are commonly detected in patients with anti-mitochondrial antibody M2 (AMA-M2)-associated myopathy. However, the prevalence of supraventricular arrhythmias in unselected AMA-M2-positive patients and the impact of AMA-M2 on supraventricular arrhythmias have yet to be fully investigated. Methods We analyzed 384 patients (116 men; age, 60 [48-69] years), who underwent AMA-M2 testing following the detection of elevated hepatobiliary enzymes. Supraventricular arrhythmias involving atrial fibrillation, atrial flutter, atrial tachycardia, sick sinus syndrome, and atrial standstill were confirmed by a 12-lead electrocardiogram, 24-hour ambulatory monitoring, and physician-assigned diagnoses within the three years before and two years after the AMA-M2 test...

Eukaryotic genomes are organised into complex higher-order structures within the nucleus, and the three-dimensional arrangement of chromosomes is functionally important for global gene regulation. The existence of supernumerary chromosome 21 in Down syndrome may perturb the nuclear architecture at different levels, which is normally optimised to maintain the physiological balance of gene expression. However, it has not been clearly elucidated whether and how aberrant configuration of chromosomes affects gene activities...

Phospholipase C-related but catalytically inactive proteins PRIP-1 and -2 are inositol-1,4,5-trisphosphate binding proteins that are encoded by independent genes. Ablation of the Prip genes in mice impairs female fertility, which is manifested by fewer pregnancies, a decreased number of pups, and the decreased and increased secretion of gonadal steroids and gonadotropins, respectively. We investigated the involvement of the PRIPs in fertility, focusing on the ovaries of Prip-1 and -2 double-knock-out (DKO) mice...

Oxaliplatin-based chemotherapy plays an important role in the treatment of colorectal liver metastases. Oxaliplatin, however, causes sinusoidal obstruction syndrome (SOS), which is characterized by portal hypertension, splenomegaly, thrombocytopenia, and liver dysfunction. SOS is diagnosed histopathologically by disruption of the sinusoidal endothelium, collagen deposition, fibrosis especially around zone 3, dilatation of the sinusoidal space and congestion. This study assessed the characteristics of a rat model of SOS...
