Phellinus baumii is a yellow mushroom long used in alternative medicine in Korea and other central Asian countries. To identify genes affected by a single or 7-day oral administration of a water extract of Ph. Baumii, mouse liver tissue was analyzed using microarrays. The results showed that 8 and 23 genes were upregulated and 3 and 11 genes downregulated more than 3-fold by single and multiple oral administrations of 100 mg/kg PBE, respectively. Among the upregulated genes, the expression of 3 flavin-containing monooxygenase (Fmo) family genes, Fmo2-4, was upregulated in a concentration-dependent manner...

PURPOSE OF REVIEW: A generalized single blood pressure (BP) goal may appear not suitable to achieve an optimal stroke prevention at the individual level. The aim of the present review is to consider the clinical relevance of individualized BP goal according to patient's age, comorbidities and established cerebrovascular disease. RECENT FINDINGS: Observational and interventional data support heterogeneity in target organ prevention in that lower BP values than recommended by hypertension guidelines are associated with further stroke risk reduction...

Diabetic nephropathy (DN) is a serious complication of diabetes mellitus, and its prevalence has been increasing in developed countries. Diabetic nephropathy has become the most common single cause of end-stage renal disease worldwide. Oxidative stress and inflammation factors are hypothesized to play a role in the development of late diabetes complications. Chronic hyperglycemia increases oxidative stress, significantly modifies the structure and function of proteins and lipids, and induces glycoxidation and peroxidation...

BACKGROUND: Elabela (ELA) is a recently identified apelin receptor agonist essential for cardiac development, but its biology and therapeutic potential are unclear. In humans ELA transcripts are detected in embryonic stem cells, induced pluripotent stem cells, kidney, heart and blood vessels. ELA through the apelin receptor promotes angiogenesis in vitro, relaxes murine aortic blood vessels and attenuates high blood pressure in vivo. The apelin receptor when bound to its original ligand, apelin, exerts peripheral vasodilatory and positive inotropic effects, conferring cardioprotection in vivo...

Calcific uremic arteriolopathy (CUA), also known as calciphylaxis, is a rare condition most frequently seen in patients with advanced chronic kidney disease. The clinical picture is characterized by painful skin lesions and ulcerations. The underlying pathology is medial calcification and intimal proliferation with microthrombi of small arteries. CUA is commonly associated with secondary hyperparathyroidism and high serum calcium and phosphate products. This article reports an atypical case where CUA developed after parathyroidectomy and in the course of treatment of hungry bone syndrome...

The anemia of chronic kidney disease (CKD) is a common comorbidity seen in kidney diseases. It is also associated with increased cardiovascular morbidity and mortality and diminished quality of life. Often, patients with CKD of different stages require erythropoiesis-stimulating agents (ESAs) to maintain their hemoglobin (Hb) within the target range. Darbepoetin alfa is a newer ESA with a longer half-life than recombinant human erythropoietin (EPO). The objective of this study is to assess the efficacy and safety profile of twice-monthly (Q2W) and once a month (1QM) darbepoetin alfa in CKD patients, not on dialysis...

A shear wave velocity (SWV) value obtained by the acoustic radiation force impulse technique depends on tissue elasticity. We investigated the relationship between SWV values and the estimated glomerular filtration rate (eGFR) in children with chronic kidney disease. A total of 29 patients were enrolled in the study. There were 18 primary and 11 secondary cases of vesicoureteral reflux. eGFR was calculated using Schwartz's formulas (2012). Partial eGFR for each kidney was assessed by multiplying the eGFR by the percentage of renal function measured by means of renal (99m)Tc-dimercaptosuccinic acid scintigraphy...

AIMS: Despite several studies reporting similar outcomes for peritoneal dialysis (PD) and hemodialysis (HD), the former is underused worldwide, with a PD prevalence of 15% in Italy. In 2008, the Unit of Nephrology and Dialysis of the Healthcare Trust of the Autonomous Province of Trento implemented a successful PD program which has increased the proportion of PD incident patients from 7 to 47%. We aimed to assess the effect of this extensive use of PD by comparing HD and PD in terms of survival and time-to-transplantation...

Kidney cancer is not a single disease but is made up of a number of different types of cancer classified by histology that are disparate in presentation, clinical course, and genetic basis. Studies of families with inherited renal cell carcinoma (RCC) have provided the basis for our understanding of the causative genes and altered metabolic pathways in renal cancer with different histologies. Von Hippel-Lindau disease was the first renal cancer disorder with a defined genetic basis. Over the next two decades, the genes responsible for a number of other inherited renal cancer syndromes including hereditary papillary renal carcinoma, Birt-Hogg-Dube´syndrome, hereditary leiomyomatosis and renal cell carcinoma, and succinate dehydrogenase-associated renal cancer were identified...

It is well known that cytochrome c (Cyt c) is a crucial death regulator that triggers programmed cell death, apoptosis. Here, we report on the successful application of an aptamer bioconjugated nanoclusters for the detection of apoptosis based on release of cytochrome c from mitochondria in lysates human embryonic kidney cells HEK293T. The aptamer-conjugated silver nanoclusters (Apt@AgNCs) were synthesized and immobilized on gold electrode for impedimetric detection of Cyt c over the range of 0.15-375nM. It was found that the presence of Ag(I) ions shell at the surface of prepared NCs could increase their affinity to the donor groups (COO(-) and some amine groups in its deprotonated form, NH2) of cysteine attached on the gold electrode surface...

Many researchers now have available multiple high-dimensional molecular and clinical datasets when studying a disease. As we enter this multi-omic era of data analysis, new approaches that combine different levels of data (e.g. at the genomic and epigenomic levels) are required to fully capitalize on this opportunity. In this work, we outline a new approach to multi-omic data integration, which combines molecular and clinical predictors as part of a single analysis to create a prognostic risk score for clear cell renal cell carcinoma...

BACKGROUND: The Luminex(®) single antigen bead assay (SAB) is the method of choice for monitoring the treatment for antibody-mediated rejection (AMR). A ⩾50% reduction of the dominant donor-specific antibody (IgG-DSA) mean fluorescence intensity (MFI) has been associated with improved kidney allograft survival, and C1q-fixing DSA activity is associated with poor outcomes in patients with AMR. We aimed to investigate if C1q-DSA can be used as a reliable predictor of response to therapy and allograft survival in patients with biopsy-proven AMR...
