Kidney Allograft Failure in the Steroid-Free Immunosuppression Era: A Matched Case-Control Study.

We studied the causes and predictors of death-censored kidney allograft failure among 1670 kidney recipients transplanted at our center in the corticosteroid-free maintenance immunosuppression era. As of January 1, 2012, we identified 137 recipients with allograft failure; 130 of them (cases) were matched 1-1 for recipient age, calendar year of transplant and donor type with 130 recipients with fu...

To evaluate the effects of surgical anatomical correction on lower urinary tract symptoms (LUTS) in patients with a pelvic anterior compartment defect (PACD).

Frequency and Antibiotic Resistance of Bacteria Implicated in Community Urinary Tract Infections in North Aveiro Between 2011 and 2014.

The present study aims to evaluate the predominance of uropathogens responsible for urinary tract infection (UTI) and determine their resistance patterns, to assess if the recommended empirical treatment is appropriate for the studied population. Samples were collected in Aveiro (Portugal) from an ambulatory service between June 2011 and June 2014.

Systematic Review and Meta-analysis: Fecal Microbiota Transplantation for Treatment of Active Ulcerative Colitis.

Changes in the colonic microbiota may play a role in the pathogenesis of ulcerative colitis (UC) and restoration of healthy gut microbiota may ameliorate disease. A systematic review and meta-analysis was conducted to assess fecal microbiota transplantation (FMT) as a treatment for active UC.

Comprehensive metabolic characterization of serum osteocalcin action in a large non-diabetic sample.

Recent research suggested a metabolic implication of osteocalcin (OCN) in e.g. insulin sensitivity or steroid production. We used an untargeted metabolomics approach by analyzing plasma and urine samples of 931 participants using mass spectrometry to reveal further metabolic actions of OCN. Several detected relations between OCN and metabolites were strongly linked to renal function, however, a nu...

An Active and Robust Bifunctional Oxygen Electrocatalyst through Carbon-Free Hierarchical Functionalization.

A hierarchically functionalized hybrid electrode for Zn-air batteries is discussed that requires no carbon. Instead, an oxygen evolution reaction (OER)-active, porous, conductive, and corrosion-resistant nitride Ni3 FeN is used as a support for oxygen reduction reaction (ORR)-active ordered intermetallic Fe3 Pt NPs. The porosity in the Ni3 FeN substrate is an important enabling factor for the high...

Power and coherence of cortical High Frequency Oscillations during wakefulness and sleep.

Recently, a novel type of fast cortical oscillatory activity that occurs between 110 and 160 Hz (high-frequency oscillations (HFO)) was described. HFO are modulated by the theta rhythm in hippocampus and neocortex during active wakefulness and REM sleep. Since theta-HFO coupling increases during REM, a role for HFO in memory consolidation has been proposed. However, global properties like the cort...

Dose-dependent response to 3-nitrobenzanthrone exposure in human urothelial cancer cells.

A product of incomplete combustion of diesel fuel, 3-nitrobenzanthrone (3-NBA), has been classified as a cancer-causing substance. It first gained attention as a potential urinary bladder carcinogen due to the presence of its metabolite in urine and formation of DNA adducts. The aim of the present study was to characterise the dose-response relationship of 3-NBA in human urothelial cancer cell lin...

Effects of mutations on active site conformation and dynamics of RNA-dependent RNA polymerase from Coxsackievirus B3.

Recent crystal structures of RNA-dependent RNA polymerase (3D(pol)) from Coxsackievirus B3 (CVB3) revealed that a tyrosine mutation at Phe364 (F364Y) resulted in structures with open active site whereas a hydrophobic mutation at Phe364 (F364A) led to conformations with closed active site. Besides, the crystal structures showed that the F364W mutation had no preference between the open and closed a...

Off-line microextraction by packed sorbent combined with on solid support derivatization and GC-MS: Application for the analysis of five pyrethroid metabolites in urine samples.

A novel, fast and eco-friendly analytical method using microextraction by packed sorbent coupled to large volume injection-gas chromatography-mass spectrometry (MEPS-LVI-GC-MS) was developed for the determination of five pyrethroid metabolites (cis-2,2-dimethyl-3-(2-chloro-3,3,3-trifluoro-1-propenyl)-cyclopropanecarboxylic acid, cis/trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylic...

Quantification of 7-aminoflunitrazepam in human urine by polymeric monolith-based capillary liquid chromatography coupled to tandem mass spectrometry.

Using a simple liquid-liquid extraction (LLE) procedure for sample pretreatment, 7-Aminoflunitrazepam (7-aminoFM2), a major metabolite of flunitrazepam (FM2), was determined in urine samples by polymeric monolith-based capillary liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). The linearity was found in the range of 0.1-50ngmL(-1) with a method detection limit (signal-to-noise...

Gas chromatographic-mass spectrometric analysis of urinary volatile organic metabolites: Optimization of the HS-SPME procedure and sample storage conditions.

Non-targeted metabolomics research of human volatile urinary metabolome can be used to identify potential biomarkers associated with the changes in metabolism related to various health disorders. To ensure reliable analysis of urinary volatile organic metabolites (VOMs) by gas chromatography-mass spectrometry (GC-MS), parameters affecting the headspace-solid phase microextraction (HS-SPME) procedu...

Inhibitory effects of Dianthi Herba ethanolic extract on inflammatory and nociceptive responses in murine macrophages and mouse models of abdominal writhing and ear edema.

Dianthi Herba is a traditional herbal medicine used to treat inflammatory-related diseases including acute pyelonephritis, cystitis, laryngopharyngitis, and urethritis.

Urinary Incontinence and Indwelling Urinary Catheters as Predictors of Death after New-Onset Stroke: A Report of the South London Stroke Register.

To explore the relationship between indwelling urinary catheters (IUCs), urinary incontinence (UI), and death in the poststroke period and to determine when, after the neurological event, UI has the best ability to predict 1-year mortality.

Decreased Monoamine Oxidase a Expression and Activity in the Bladders of Rats with Partial Outlet Obstruction.

OBJECTIVE To investigate changes in expression and activity of monoamine oxidase A (MAO-A) in rats with partial bladder outlet obstruction (pBOO). Previous studies suggested that monoamines, such as serotonin (5-hydroxytryptamine; 5-HT) and noradrenaline (NA), are involved in bladder hyperactivity secondary to pBOO. However, little is known about the role of MAO-A, an enzyme oxidizing 5-HT and NA,...
