BACKGROUND: Classic galactosemia results from deficient activity of galactose-1-phosphate uridylyltransferase (GALT), a key enzyme of galactose metabolism. Despite early diagnosis and early postnatal therapeutic intervention, patients still develop neurologic and fertility impairments. Prenatal developmental toxicity has been hypothesized as a determinant factor of disease. In order to shed light on the importance of prenatal GALT activity, several studies have examined GALT activity throughout development...

BACKGROUND: Vascular occlusion is a rare, but serious complication after kidney transplantation often resulting in graft loss. We therefore aimed to develop an experimental porcine model for stepwise reduction of the renal venous blood flow and to compare an implantable Doppler probe and microdialysis for fast detection of vascular occlusion. METHODS: In 20 pigs, implantable Doppler probes were placed on the renal artery and vein and a microdialysis catheter was placed in the renal cortex...

Diabetes and hypertension are at present the major causes of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide. The stages 0-5 of CKD are defined according to the estimated glomerular filtration rate. The term chronic renal failure (CRF) typically corresponds to CKD stages 3-5. Cardiovascular disease is the main cause of morbidity and mortality in patients of CRF and ESRD. This study was undertaken to analyze the age and sex incidence, clinical features, etiology, pathology of various organs in detail, and causes of death of CRF patients...

Chronic kidney disease (CKD) is associated with a range of metabolic bone diseases. Fracture rates are higher in CKD patients than age-matched controls throughout all the five stages of CKD. Dialysis patients have 4 times as many hip fractures as expected for their age. CKD forms an independent risk factor for osteoporosis, even in the absence of traditional risk factors. This study was carried out at the nephrology unit in a tertiary care center of Kashmir to know the prevalence of osteoporosis in CKD patients having glomerular filtration rate (GFR) <60 mL/min (stages 3-5)...

Renal osteodystrophy (ROD), the histologic bone lesions of chronic kidney disease (CKD), is now included in a wider syndrome with laboratory abnormalities of mineral metabolism and extra-skeletal calcifications or CKD-mineral and bone disorders (CKD-MBD), to highlight the increased burden of mortality. Aging people, frequently identified as early CKD, could suffer from either the classical age-related osteoporosis (OP) or ROD. Distinguishing between these two bone diseases may not be easy without bone biopsy...

Obesity has become a worldwide epidemic, and its prevalence has been projected to grow by 40% in the next decade. This increasing prevalence has implications for the risk of diabetes, cardiovascular disease, and also for chronic kidney disease (CKD). A high body mass index is one of the strongest risk factors for new-onset CKD. In individuals affected by obesity, a compensatory hyperfiltration occurs to meet the heightened metabolic demands of the increased body weight. The increase in intraglomerular pressure can damage the kidneys and raise the risk of developing CKD in the long term...

Kidneys are highly vascularized and contain many distinct vascular beds. However, the origins and roles of developing renal endothelial cells in the formation of the kidney are unclear. We have shown that the Foxd1-positive renal stroma gives rise to endothelial marker expressing progenitors that are incorporated within a subset of peritubular capillaries; however, the significance of these cells is unclear. The purpose of this study was to determine whether deletion of Flk1 in the Foxd1 stroma was important for renal development...

BACKGROUND: Despite improvements in the management of severely injured patients, development of multiple organ dysfunction syndrome (MODS) remains a morbid complication of traumatic shock. One of the key attributes of MODS is a profound bioenergetics crisis, for which the mediators and mechanisms are poorly understood. We hypothesized that metabolic uncoupling using an experimental PI3-kinase inhibitor, LY294002 (LY), may prevent mitochondrial abnormalities that lead to the generation of mitochondrial DNA (mtDNA) damage and the release of mtDNA damage associated molecular patterns (DAMPs) METHODS: 16 swine were studied using LY294002 (LY), a non-selective PI3-KI: Animals were assigned to Trauma only (TO, N=3); LY drug only (LYO, N=3); and Experimental (N=10), trauma + drug (LY+T) groups...

Fumarase catalyzes the interconversion of fumarate and L-malate in the tricarboxylic acid cycle. The Dahl salt-sensitive (SS) rat, a model of salt-sensitive hypertension, exhibits fumarase insufficiencies. To investigate the mechanism mediating the effect of fumarase-related metabolites on hypertension, we considered the pathway in which L-malate can be converted to oxaloacetate, aspartate, argininosuccinate, and L-arginine, the substrate of nitric oxide (NO) synthase. The levels of aspartate, citrulline, L-arginine, and NO were significantly decreased in the kidneys of SS rats compared to salt-insensitive consomic SS...

INTRODUCTION: Ganglioneuromas are rare benign neoplasms of the sympathetic nervous system. We describe the case of an incidentally found ganglioneuroma in a woman. To our knowledge this is the first described case of robotic excision of a retroperitoneal ganglioneuroma. CASE: A 41-year-old female had an incidental retroperitoneal mass found during a routine US. CT scan and MRI showed an 8.3cm homogeneous mass, adjacent to left kidney upper pole, with peripheral contrast enhancement...

Iron is an essential microelement for almost all living organisms, while an excess of iron is toxic, thus maintenance of iron homeostasis is vital. As iron storage protein, ferritin plays an important role in iron metabolism. In the present study, we cloned and characterized the ferritin H subunit from Megalobrama amblycephala, termed as MamFerH. An iron-responsive element (IRE) was predicted in the 5' untranslated region (UTR) of MamFerH, while its bulge structural was different from that of the reported ferritin M subunit (MamFerM)...

Patients affected by chronic kidney disease (CKD) exhibit a high risk of cardiovascular mortality that is poorly explained by traditional risk factors. There is a growing awareness about the role of derangement of mineral metabolism that is currently accepted as a trigger and sustainer of cardiovascular disease (CVD) in CKD patients. The synthetic definition of CKD mineral and bone disorder (CKD-MBD) split the concept that the indexes of mineral metabolism extend their effects beyond the bone until the vascular wall and metabolic milieu of CKD patients through complex pathways...

A direct and independent association between serum phosphate (P) levels and mortality has been reported. High circulating P concentrations, still within the normal range, was associated with unfavourable outcomes in normal subjects as well as in chronic kidney disease (CKD) patients. Experimental data support the notion that P overload may hamper survival expectancy, directly inducing vascular, skeletal, and renal ageing. The balance of P results from dietary intake, intestinal absorption, glomerular filtration, tubular resorption, and hormonal asset...

Human exposure to arsenic in drinking water is known to be associated with the development of bladder, lung, kidney, and skin cancers. The molecular mechanisms underlying the carcinogenic effects of arsenic species remain incompletely understood. DNA interstrand cross-links (ICLs) are among the most cytotoxic type of DNA lesions that block DNA replication and transcription, and these lesions can be induced by endogenous metabolism and by exposure to exogenous agents. Fanconi anemia (FA) is a congenital disorder manifested with elevated sensitivity toward DNA interstrand cross-linking agents...
