The metabolic enzyme cytidine triphosphate synthase has recently been found to form micron-sized filamentous structures termed cytoophidia, which are evolutionarily conserved across prokaryotes and eukaryotes. The cytoophidium represents a novel type of membraneless organelle and behaves dynamically inside the cell. The question of how cytoophidia transport is mediated, however, remains unanswered...
To undertake a prospective point prevalence study of the prevalence of active Charcot neuro-inflammatory osteoarthropathy (Charcot disease) in a circumscribed part of England and to audit the time elapsing between disease onset and first diagnosis.
Single-atom catalysts exhibit high selectivity in hydrogenation due to their isolated active sites which ensure uniform adsorption configurations of substrate molecules. Compared with the achievement in catalytic selectivity, there is still a long way to go in exploiting the catalytic activity of single-atom catalysts. Herein, we developed highly active and selective catalysts in selective hydroge...
To investigate the efficacy of low dose triamcinolone injection for effectiveness and durability in interstitial cystitis/bladder pain syndrome (IC/BPS) patients with Hunner Lesions (HL).
Ganoderma lucidum (GL) has been traditionally used in oriental medicine as superior health tonic, and there are numerous scientific evidences of its antitumorigenic activities.
The mid-urethral sling (MUS) procedure is the gold-standard for the surgical treatment of stress urinary incontinence (SUI). Urethro-vesical sling exposure is one of the most serious complications of this procedure. We describe the treatment and follow-up of 18 patients with bladder or urethral sling exposure.
The current study sought to investigate the effects of exposure therapy on suicidal ideation (SI), as well as potential mechanistic pathways of SI reduction among active duty military personnel.
To investigate whether a history of non-muscle-invasive bladder cancer (NMIBC) plays a prognostic role in patients with muscle-invasive bladder cancer (MIBC) treated with radical cystectomy in the era when neoadjuvant chemotherapy was established as standard therapy for MIBC.
To determine whether periurethral cleaning with water before indwelling urinary catheterization increases the risk of urinary tract infections (UTIs) compared with studies using anti-infective agents.
Urinary 8-isoprostane is an established biomarker for lipid peroxidation. However, the association between its pre-diagnostic levels and cancer incidence has rarely been evaluated.
Protein lysine methyltransferases (PKMTs) catalyze the methylation of lysine residues on many different cellular proteins. Despite extensive biochemical and structural studies, focusing on PKMT active site-peptide interactions, little is known regarding how PKMTs recognize globular substrates. To examine whether these enzymes recognize protein substrates through interactions that take place outsid...
Mitochondrial dysfunction plays an important role in the pathogenesis and progression of chronic kidney disease (CKD). We study the relation between urinary mitochondrial DNA (mtDNA) levels and renal dysfunction in non-diabetic CKD.
Intravesical Bacillus Calmette-Guérin (BCG) is widely used for high-risk, non-muscle-invasive bladder cancer. We describe four cases which illustrate the spectrum of BCG-induced complications, varying from granulomatous prostatitis to sepsis. Considerable debate exists whether inflammation or infection is the predominant mechanism in the pathogenesis of BCG-disease. In two patients with systemic ...
Urinothorax refers to the presence of urine in the pleural space. Urinothorax is an infrequent and underdiagnosed pathology, with few cases reported, and these often suspected only with hindsight. It is usually a transudative pleural effusion. We report a case of urinothorax presenting as a purulent pleural effusion. Management of the urinothorax required antibiotics and surgical unblocking of the...
This video provides a case report of a 16-year-old male patient who underwent bladder enlargement with a catheterized conduit under Macedo's technique. This technique involves the use of a segment of the distal ileum with a flap that is used for confection of the conduit. Key points include: 1) skin incision planning; 2) bladder release to allow a tension-free anastomosis; 3) reservoir and a condu...
Re. "Diffusion weighted magnetic resonance imaging is more sensitive than dimercaptosuccinic acid scintigraphy in detecting parenchymal lesions in children with acute pyelonephritis: A prospective study".
Bladder calculi are a known complication of bladder augmentation. Open cystolithotomy remains the preferred option for treating large or multiple stones. Increasingly, however, minimal access techniques have been used. Reports of Mitrofanoff cystolitholapaxy are rare and have been limited to adults. This study presented a two centre series of children treated by cystolitholapaxy via the Mitrofanof...
The aim of this study was to investigate environmental and lifestyle factors affecting exposure to PAHs in the general population in a large city of the Middle East (Tehran) by measuring urinary monohydroxy polycyclic aromatic hydrocarbons (OH-PAHs) and establishing relationships between PAHs exposure and related factors. Urine samples were collected from 222 randomly chosen subjects who were livi...
