Is there association between chronic kidney disease and dental caries? A case-controlled study
2018
Background The purpose of this study was to assess the association between chronic kidney diseases (CKD) and dental caries. Material and Methods 107 patients with CKD and 107 with no systemic alteration were randomly included. DMFT (decayed, missing, and filled teeth), plaque index, colony-forming units (CFU) of Streptococcus mutans and salivary composition (IgA total, IgA anti- Streptococcus mutans, calcium and urea) were evaluated. McNemar and Wilcoxon tests were used to compare test and control groups. Spearman test was used to correlate time of hemodialysis and variables studied. Associations between variables were evaluated by logistic regression analysis. Results The number of filled …
Oxidation of tienilic acid by human yeast-expressed cytochromes P-450 2C8, 2C9, 2C18 and 2C19. Evidence that this drug is a mechanism-based inhibitor…
1996
Oxidation of tienilic acid by human cytochromes P-450 (CYP) 2C9, 2C18, 2C8 and 2C19 was studied using recombinant enzymes expressed in yeast. CYP 2C9 was the best catalyst for 5-hydroxylation of tienilic acid (K(m) = 5 +/- 1 microM, kcat = 1.7 +/- 0.2 min-1), 30-fold more potent in terms of kcat/K(m) than CYP 2C18 (K(m) = 150 +/- 15 microM, kcat = 1.8 +/- 0.2 min-1) and 300-fold more potent than CYP 2C8 (K(m) = 145 +/- 15 microM, kcat = 0.2 +/- 0.1 min-1). CYP 2C19 was unable to catalyze this hydroxylation under our experimental conditions. During this study, a marked effect of the ionic strength on the activities (hydroxylations of tienilic acid and tolbutamide) of these cytochromes P-450 …
Nuclear localization of the protein encoded by the Wilms’ tumor gene WT1 in embryonic and adult tissues
1993
ABSTRACT The human Wilms’ tumor gene WT1 encodes a putative transcription factor implicated in tumorigenesis and in specifying normal urogenital development. We have studied the distribution of WT1 protein and mRNA using immunohistochemistry and in situ hybridization. Monoclonal antibodies were raised against a peptide specific to the first alternative splice site of WT1. Two antibodies specifically reacted on Western blot to this WT1 isoform. Immunofluorescence localized WT1 protein to podocytes during mesonephric and metanephric development. In situ hybridization revealed a similar pattern of expression except that WT1 mRNA was also present in metanephric blastema and renal vesicles. Mess…
Protein oxidation in chronic kidney disease.
2013
An imbalance between oxidative processes and antioxidant systems has been widely demonstrated in chronic kidney diseases (CKD). In this study we enrolled 26 healthy subjects, 27 patients with CKD on conservative treatment (CT-CKD) with various degrees of renal failure, and 31 CKD subjects in haemodialysis treatment (HD-CKD), evaluated before and after a standard haemodialysis session. In each group we measured protein carbonyl groups (PC) as an index of protein oxidation, lipid peroxidation (TBARS) and two plasma markers of leukocyte activation, elastase and myeloperoxidase (MPO). In CT-CKD subjects the PC level was significantly higher than in normal controls, and it was negatively correla…
The dapagliflozin and prevention of adverse outcomes in chronic kidney disease (DAPA-CKD) trial: baseline characteristics
2020
Abstract Background The Dapagliflozin and Prevention of Adverse outcomes in Chronic Kidney Disease (DAPA-CKD; NCT03036150) trial was designed to assess the effect of the sodium–glucose co-transporter 2 (SGLT2) inhibitor dapagliflozin on kidney and cardiovascular events in participants with CKD with and without type 2 diabetes (T2D). This analysis reports the baseline characteristics of those recruited, comparing them with those enrolled in other trials. Methods In DAPA-CKD, 4304 participants with a urinary albumin:creatinine ratio (UACR) ≥200 mg/g and estimated glomerular filtration rate (eGFR) between 25 and 75 mL/min/1.73 m2 were randomized to dapagliflozin 10 mg once daily or placebo. Me…
Enhanced glomerular Toll-like receptor 4 expression and signaling in patients with type 2 diabetic nephropathy and microalbuminuria
2014
Toll-like receptor 4 (TLR4), a component of the innate immune system, is recognized to promote tubulointerstitial inflammation in overt diabetic nephropathy (DN). However, there is no information on immune activation in resident renal cells at an early stage of human DN. In order to investigate this, we studied TLR4 gene and protein expression and TLR4 downward signaling in kidney biopsies of 12 patients with type 2 diabetes and microalbuminuria, and compared them with 11 patients with overt DN, 10 with minimal change disease (MCD), and control kidneys from 13 patients undergoing surgery for a small renal mass. Both in microalbuminuria and in overt DN, TLR4 mRNA and protein were overexpress…
Analysis of methylation and mRNA expression status ofFADD andFAS genes in patients with oral squamous cell carcinoma
2014
Background: Apoptosis is an important mechanism that is responsible for the physiological deletion of harmful, damaged, or unwanted cells. Changed expression of apoptosis-related genes may lead to abnormal cell proliferation and finally to tumorigenesis. Our aims were to analyze the promoter methylation and gene expression profiles of FADD and FAS genes in risk of OSCC. Material and Methods: we analyze the promoter methylation status of FADD and FAS genes using Methylation - Specific PCR (MSP) in 86 OSCC tissues were kept in paraffin and 68 normal oral tissues applied as control. Also, FADD and FAS genes expression were analyzed in 19 cases and 20 normal specimens by Real-Time Reverse- Tran…
Cardiovascular risk factors and the impact on prognosis in patients with chronic kidney disease secondary to autosomal dominant polycystic kidney dis…
2021
Background: Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent hereditary renal disease. There is an increased rate of cardiovascular disease (CVD) in ADPKD. In this study, we evaluate the prevalence of cardiovascular risk factors, the achievement rates for treatment goals and cardiovascular events (CVE) in ADPKD and their relations with asymptomatic CVD in CKD from other etiologies (CKDoe) and controls. Methods: We evaluated 2445 CKD patients (2010–2012). The information collected was: clinical, anthropometric and analytical parameters, treatments and CVD evaluation (intima-media thickness (IMT), atheromatous plaque presence and ankle-brachial index (ABI)). Laborator…
Risk factors for high fall risk in elderly patients with chronic kidney disease
2022
Purpose: Patients with chronic kidney disease (CKD) usually represent an aging population, and both older age and CKD are associated with a higher risk of falling. Studies on risk factors among subjects with CKD are lacking. Methods: Records of outpatients from one geriatric clinic in Turkey were retrospectively reviewed. A result of ≥ 13.5 s on the timed up and go (TUG) test was accepted as a high risk of falls. Independent predictors of an increased risk of falls among subjects with CKD (estimated glomerular filtration rate of < 60 mL/min/1.73 m2) were identified using logistic regression models. Results: Patients with CKD (n = 205), represented the 20.2% of the entire cohort and was i…
Kinetics of serum total and free prostate-specific antigen (PSA) after extended multisite prostate biopsy: Comparison among biopsy, transurethral res…
2008
Abstract Background The kinetics and reproducibility of serum prostate-specific antigen (PSA) following extended multisite biopsies are unknown. The aim of this study was to examine the kinetics of hematogenous leakage of PSA molecules by comparing the postintervention PSA manner among extended biopsies, transurethral resection of the prostate (TURP) and biopsy plus TURP. Methods Total and free PSA values were examined before and sequentially after intervention (at 1 hour, 24 hours, 2 days, 14 days, and 28 days), in patients who underwent 14-core prostate biopsy (Biopsy, n = 53), TURP (TURP, n = 21), or prostate biopsy plus TURP (Biopsy+TURP, n = 18). Results Ten patients in the Biopsy grou…
