INTRODUCTION: Venous thrombosis is a serious surgical complication that frequently results in loss of kidney graft. CASE PRESENTATION: We report the case of a female patient recipient of a decease kidney transplant that in the tenth postoperative presented with hematuria, graft pain and oliguria. Ultrasound examination was suggestive of venous thrombosis with abnormal doppler waveform pattern and reversal of diastolic flow. She underwent emergency surgical intervention after 2h of diagnosis...

Ethanamizuril (EZL) is a novel anti-coccidial triazine synthesized by the Shanghai Veterinary Research Institute of the Chinese Academy of Agricultural Sciences. As a novel coccidiostat, it is essential to study its residue in food animal tissues. In this study, a reliable UPLC method for the determination of ethanamizuril (EZL) and one of its metabolites (M3) in chicken muscle, skin and fat, liver, and kidney samples was developed. Analytes were extracted using acetonitrile and 10% sodium carbonate solution, defatted by n-hexane, and further purified by using an Oasis MCX cartridge...

PURPOSE: Although primarily a mental health disorder, anorexia nervosa (AN) has many physical consequences. Among them, the consequences on kidney function are often underestimated. We evaluated renal function in adolescent AN inpatients and investigated the correlation between the GFR and intrinsic patient characteristics. METHODS: A single-center retrospective study was conducted on 51 patients hospitalized for the restrictive type of AN in 2013. Data were divided into: (1) medical history of AN; (2) growth parameters and vital signs upon admission; and (3) blood tests...

In this review, we provide an updated summary on colistin pharmacokinetics and pharmacodynamics. Colistin is an old molecule that is frequently used as last-line treatment for infections caused by multidrug-resistant Gram-negative bacteria. Colistin is a decapeptide administered either as a prodrug, colistin methanesulfonate (CMS), when used intravenously, or as colistin sulfate when used orally. Because colistin binds to laboratory materials, many experimental issues are raised and studies on colistin can be tricky...

To assess feasibility, efficacy and safety of carbon dioxide (CO2) digital subtraction angiography (DSA) to guide endovascular aneurysm repair (EVAR) in a cohort of patients with chronic kidney disease (CKD). After Ethical Committee approval, the records of 13 patients (all male, mean age 74.6 ± 8.0 years) with CKD, who underwent EVAR to exclude an abdominal aortic aneurysm (AAA) under CO2 angiography guidance, were reviewed. The AAA to be excluded had a mean diameter of 52.0 ± 8.0 mm. CO2 angiography was performed by automatic (n = 7) or hand (n = 6) injection...

Oxidative stress (OS) and fluctuating asymmetry (FA) as risk markers for environmental stress are widely used to predict changes in the health and fitness of many animals exposed to pollutants. However, from the perspective of protecting declining amphibians, it remains to be verified which one would be a reliable indicator for amphibians exposed to long-term heavy metal pollution under natural conditions. In this study, the OS and FA of Bufo raddei exposed to natural heavy metal pollution were analyzed to determine which marker is more accurate for indicating heavy metal-induced stress...

cMyc is a vital transcription factor that involves in the regulation of cell proliferation, growth, differentiation, and apoptosis. In the present study, cMyc in Larimichthys crocea (Lc-cMyc) was cloned and analyzed for investigating its function. The full-length cDNA of Lc-cMyc was 2089 bp encoding a 440-amino-acid protein (Lc-cMyc). Lc-cMyc had the characteristic helix-loop-helix-leucine-zipper (HLH-LZ) DNA-binding domain and highly conservative in evolution. The expression of Lc-cMyc was detected by quantitative real-time PCR (qRT-PCR) and in situ hybridization, respectively...

Deep learning techniques are being rapidly applied to medical imaging tasks-from organ and lesion segmentation to tissue and tumor classification. These techniques are becoming the leading algorithmic approaches to solve inherently difficult image processing tasks. Currently, the most critical requirement for successful implementation lies in the need for relatively large datasets that can be used for training the deep learning networks. Based on our initial studies of MR imaging examinations of the kidneys of patients affected by polycystic kidney disease (PKD), we have generated a unique database of imaging data and corresponding reference standard segmentations of polycystic kidneys...

A direct correlation between brain iron and Alzheimer's disease (AD) raises questions regarding the transport of non-transferrin-bound iron (NTBI), a toxic but less researched pool of circulating iron that is likely to increase due to pathological and/or iatrogenic systemic iron overload. Here, we compared the distribution of radiolabeled-NTBI (59Fe-NTBI) and transferrin-bound iron (59Fe-Tf) in mouse models of iron overload in the absence or presence of inflammation. Following a short pulse, most of the 59Fe-NTBI was taken up by the liver, followed by the kidney, pancreas, and heart...

Mesenchymal to epithelial transition (MET) and epithelial to mesenchymal transition (EMT) are important processes in kidney development. Failure to undergo MET during development leads to the initiation of Wilms tumor (WT) whereas EMT contributes to the development of renal cell carcinomas (RCC). The role of calcium regulators in governing these processes is becoming evident. We demonstrated earlier that Na+/Ca2+ exchanger 1 (NCX1), a major calcium exporter in renal epithelial cells, regulates epithelial cell motility...

Nephrin is a core component of podocyte (glomerular epithelial cell) slit diaphragm and is required for kidney ultrafiltration. Down-regulation or mislocalization of nephrin has been observed in diabetic kidney disease (DKD), characterized by albuminuria. Here, we investigate the role of protein kinase C and casein kinase 2 substrate in neurons 2 (PACSIN2), a regulator of endocytosis and recycling, in the trafficking of nephrin and development of DKD. We observe that PACSIN2 is up-regulated and nephrin mislocalized in podocytes of obese Zucker Diabetic Fatty (ZDF) rats that have altered renal function...

The difference between involved minus uninvolved serum free light chains (dFLC) has been established as invaluable hematologic parameter in systemic light chain amyloidosis (AL). However, patients with initial dFLC below 50mg/L are currently deemed not evaluable for response to therapy. Therefore, we aimed to characterize this subgroup and to define novel hematologic response parameters. We retrospectively analyzed 783 AL patients newly diagnosed at our center between 2002 and 2016. Patients with dFLC<50 showed a smaller bone marrow plasmacytosis (7% vs...

The mineralocorticoid receptor (MR) mediates the actions of two important adrenal corticosteroid hormones, aldosterone and cortisol. The cell signalling roles of the MR in vivo have expanded enormously since the cloning of human MR gene 30 years ago and the first MR gene knockout in mice nearly 20 years ago. Complete ablation of the MR revealed important roles postnatally for regulation of kidney epithelial functions, with MR-null mice dying 1-2 weeks postnatally from renal salt wasting and hyperkalaemia, with elevated plasma renin and aldosterone...

Brd2 is a member of the bromodomain-extraterminal domain (BET) family of proteins and functions as an acetyl-histone-directed transcriptional co-regulator and recruitment scaffold in chromatin modification complexes affecting signal-dependent transcription. While Brd2 acts as a protooncogene in mammalian blood, developmental studies link it to regulation of neuronal apoptosis and epilepsy, and complete knockout of the gene is invariably embryonic lethal. In Drosophila, the Brd2 homolog acts as a maternal effect factor necessary for segment formation and identity and proper expression of homeotic loci, including Ultrabithorax and engrailed...

Rohu (Labeo rohita), an Indian Major Carp (IMC) is an economically important aquaculture species in India. Inspite of the technological advances, infectious diseases caused by viruses, bacteria and parasites have been a major limiting factor in the development and profitability of fish farms. At present, information regarding the immune status of the Indian major carps is limited. This lack of knowledge is a major impediment for establishment of effective preventive measures against broad spectrum of infectious agents...

PURPOSE: We sought to determine whether median household income (MHI) independently predicts surgical approach (partial vs. radical nephrectomy) and survival in patients with renal cell carcinoma. METHODS: The U.S. Surveillance Epidemiology and End Results Database (1988-2011) was queried to examine kidney cancer cases and linked to the Area Health Resources File. We correlated surgical approach and survival, both overall and cancer-specific, with tumor stage, age, race, sex, and income data...

BACKGROUND: Oxidative stress is one of the main pathogenic mechanisms in vancomycin-induced nephrotoxicity (VIN). Some studies suggest proximal renal tubular cell necrosis by vancomycin accumulation as a mechanism of nephrotoxicity, and other studies demonstrate that cilastatin has protective effects against drug-induced nephrotoxicity. We investigated whether cilastatin regulates P-gp expression and whether cilastation prevents VIN. MATERIALS AND METHODS: We conducted an in vitro study using an immortalized proximal tubule epithelial cell line from a normal adult human kidney (HK-2) and an in vivo study using male C57BL/6J mice...

BACKGROUND: Studies in chronic kidney disease populations suggest that the non-glomerular filtration rate (GFR) determinants of serum levels of the low-molecular-weight protein filtration markers cystatin C, β2-microglobulin (B2M), and beta-trace protein (BTP) are less affected by age, sex, and ethnicity than those of creatinine.
