All the members of microsporidia possess a unique, highly specialized invasion mechanism that involves the polar tube and spore wall. The interaction between spore wall proteins (SWPs) and polar tube proteins (PTPs) in the formation, arrangement, orderly orientation and function of the polar tube and spore wall remain to be determined. This study was undertaken to examine the protein interactions of the Nosema bombycis SWP7, SWP9 and PTPs. Co-immunoprecipitation, LC-MS/MS and yeast two hybrid data demonstrated that NbSWP9, but not NbSWP7, interacts with NbPTP1 and NbPTP2...

INTRODUCTION: Chronic kidney disease (CKD) patients have more frequent sleep disorders and cardiovascular disease than normals. Since arterial stiffness as a risk factor of atherosclerosis can be evaluated with pulse wave velocity (PWV), we aimed to investigate the prevalance of sleep quality (SQ) and the relationship between SQ and risk factors of atherosclerosis and whether there is a relationship between SQ and PWV (the indicator of arterial stiffness) in predialysis CKD patients. METHODS: This cross-sectional study was carried out in CKD patients followed at the Nephrology Department in Konya, Turkey, between November 2014 and March 2015...

Inborn errors of metabolism (IEM) are characterized by the body's inability to convert food into energy. The pathogenetic mechanism is based on defects in a variety of cellular enzymes. In addition to impairment of energy generation, accumulation of substrates may occur, which can deposit in tissue and lead to organ dysfunction. IEM can have profound implications for perioperative management, including difficult airway management, cardiac dysfunction, aspiration risk, seizures, and metabolic dysregulation. For the anesthesiologist, comprehensive knowledge is difficult to attain because of the heterogeneity of this group and the low prevalence of specific diseases...

Leslie Matalonga, Laura Gort, Antonia Ribes
Most inborn errors of metabolism (IEM) remain without effective treatment mainly due to the incapacity of conventional therapeutic approaches to target the neurological symptomatology and to ameliorate the multisystemic involvement frequently observed in these patients. However, in recent years, the therapeutic use of small molecules has emerged as a promising approach for treating this heterogeneous group of disorders. In this review, we focus on the use of therapeutically active small molecules to treat IEM, including readthrough agents, pharmacological chaperones, proteostasis regulators, substrate inhibitors, and autophagy inducers...

While Staphylococcus aureus osteomyelitis is considered to be incurable, the major bacterial reservoir in live cortical bone has remained unknown. In addition to biofilm bacteria on necrotic tissue and implants, studies have implicated intracellular infection of osteoblasts and osteocytes as a mechanism of chronic osteomyelitis. Thus, we performed the first systematic transmission electron microscopy (TEM) studies to formally define major reservoirs of S. aureus in chronically infected mouse (Balb/c J) long bone tissue...

BACKGROUND: Ovation aortic stent-graft system is a new device for the endovascular treatment of Abdominal Aortic Aneurysms achieving fixation via a 35-mm long, rigid anchored suprarenal stent and sealing stent at the infrarenal level by a means of a polymer-filling pair of inflatable O-rings, which cause narrowing of flow lumen and regional stenosis. Thus, concerns have been raised regarding hemodynamic consequences associated with this new design. Our preliminary report showed no significant increase of aortic pulse wave velocity (aPWV) immediately after implantation of the ovation in 3 patients...

Prenatal manifestations of inborn errors of metabolism (IEM) are related to severe disorders involving metabolic pathways active in the fetal period and not compensated by maternal or placental metabolism. Some prenatal imaging findings can be suggestive of such conditions-especially in cases of consanguinity and/or recurrence of symptoms-after exclusion of the most frequent nonmetabolic etiologies. Most of these prenatal imaging findings are nonspecific. They include mainly ascites and hydrops fetalis, intrauterine growth restriction (IUGR), central nervous system (CNS) anomalies, echogenic kidneys, epiphyseal stippling, craniosynostosis, and a wide spectrum of dysostoses...

BACKGROUND: Inborn errors of metabolism (IEM) are rare genetic disorders in which a single gene defect causes a clinically significant block in a metabolic pathway. Clinical problems arise due to either accumulation of substrates that are toxic or interfere with normal function, or deficiency of the products that are used to synthesize essential compounds. There is no report of screening results or confirmed cases of IEM in Mongolia. Only pilot study of newborn screening for congenital hypothyroidism was implemented in Mongolia, where the incidence of congenital hypothyroidism is calculated to be 1:3057 in Mongolia...

Ineffective esophageal motility (IEM) is characterized by low to very low amplitude propulsive contractions in the distal esophagus, hence primarily affecting the smooth muscle part of the esophagus. IEM is often found in patients with dysphagia or heartburn and is commonly associated with gastroesophageal reflux disease. IEM is assumed to be associated with ineffective bolus transport; however, this can be verified using impedance measurements or evaluation of a barium coated marshmallow swallow. Furthermore, water swallows may not assess accurately the motor capabilities of the esophagus, since contraction amplitude is strongly determined by the size and consistency of the bolus...

Most inborn errors of metabolism (IEMs) are inherited in an autosomal recessive manner. IEMs are one of the major concerns in Iran due to its extensive consanguineous marriages. Herein, we report two patients with two co-existent IEMs: a girl affected by classic phenylketonuria (PKU) and maple syrup urine disease (MSUD) and a male patient affected with Sandhoff disease and PKU, where Sandhoff disease was suspected due to the presence of a cherry-red spot in the eyes at 6 months which is unrelated to PKU. Sequencing of candidate genes in the first patient revealed one novel and three recurrent compound heterozygous mutations of p...

PURPOSE OF REVIEW: This review summarizes the main results of haematopoietic stem cell transplantation (HSCT) in selected inborn errors of metabolism (IEMs). RECENT FINDINGS: Early diagnosis and immediate referral to an IEM specialist is of paramount importance to improve clinical outcome: patients who are transplanted early or in their presymptomatic phase generally achieve better correction of their somatic symptoms and neurocognitive development. Long-term outcome in children with Hurler syndrome is influenced by age at HSCT, baseline clinical status and post-HSCT enzyme levels...

The polymorphic membrane protein (Pmp) paralogous families of Chlamydia trachomatis, Chlamydia pneumoniae and Chlamydia abortus are putative targets for Chlamydia vaccine development. To determine whether this is also the case for Pmp family members of C. psittaci, we analyzed transcription levels, protein production and localization of several Pmps of C. psittaci. Pmp expression profiles were characterized using quantitative real-time PCR (RT-qPCR), immunofluorescence (IF) and immuno-electron microscopy (IEM) under normal and stress conditions...

INTRODUCTION: The antiphospholipid syndrome (APS) is an acquired autoimmune disorder predisposing patients to thrombosis or pregnancy complications. Since inverted erythrocyte membranes (iEMs) might provide a physiologically relevant source of anionic phospholipids, we studied the interactions of phospholipid-binding proteins and APS antibodies using iEMs. MATERIALS & METHODS: iEMs were prepared from packed erythrocytes by hypotonic lysis. Phosphatidylserine (PS) exposure was confirmed by annexin A5 (A5) binding using fluorescence microscopy and flow cytometry...
