PURPOSE: The American Academy of Pediatrics recently recommended against routine voiding cystourethrograms (VCUGs) in children 2 to 24 months with initial febrile UTI, raising concern for delayed diagnosis and increased risk of UTI-related renal damage from vesicoureteral reflux (VUR). We assessed factors potentially associated with higher likelihood of abnormal VCUG, including ...

PEGylation of B-domain deleted factor VIII (PEG-FVIII-BDD) prolongs the half-life of the molecule by approximately twofold in animals (Mei et al., Blood 2010; 116: 270). To investigate the role of von Willebrand factor (vWF) in the catabolism of PEG-FVIII-BDD in vivo, a FVIII-BDD mutant (F8V), which is incapable of binding vWF, ...

Triclosan (TCS), an antimicrobial agent widely used in consumer and medical products, was complexed with 2-hydroxypropyl-β-cyclodextrin (HPβCD) and methyl-β-cyclodextrin (MβCD). Phase-solubility studies indicated that inclusion complexes of 1:1 stoichiometry were formed and allowed estimation of the associated equilibrium constants and free-energy changes. At the highest cyclodextrin concentrations investigated, an almost ...

AIMS: The intravenous anesthetic propofol caused episodic memory impairments in human. We hypothesized propofol caused episodic-like spatial memory retention but not acquisition impairments in rats and rescuing cAMP response element-binding protein (CREB) signaling using selective type IV phosphodiesterase (PDEIV) inhibitor rolipram reversed these effects. METHODS: Male Sprague-Dawley rats were randomized ...

Human islet isolation is associated with adverse conditions inducing apoptosis and necrosis. The aim of the present study was to assess whether antiapoptotic preconditioning can improve in vitro and posttransplant function of isolated human islets. A dose-finding study demonstrated that 200 μmol/L of the caspase-3 inhibitor Ac-DEVD-CMK was most efficient to ...

Rigid hydrocarbon macrocycles with radially-oriented π-systems and continuous conjugation have attracted great interest in recent years. These molecular belts have novel optoelectronic properties and host-guest behavior. Certain belts may also ultimately lead to a rational synthesis of carbon nanotubes. The high strain associated with the nonplanar, conjugated backbones requires the ...

BACKGROUND: A test dose is used to detect intravascular injection during neuraxial block in pediatrics. Accidental intravascular epidural local anesthetic injection might be unrecognized in anesthetized children leading to potential life-threatening complications. In children, sevoflurane anesthesia blunts the hemodynamic response when intravascular cathecolamines are administered. No studies have explored the ...

Although advances have been reported to mimic the mechanically excellent structure of natural nacre, larger-scale applications are still limited due to time and energy-intensive preparation pathways. Herein, we demonstrate that simple high-shear homogenization of dispersions containing biobased high molecular weight sodium carboxymethyl cellulose (700 kg/mol, CMC) and natural sodium montmorillonite ...

Background: Microalbuminuria screening is widely used in high-risk populations but seldom used in the general population for detecting chronic kidney disease (CKD). Systematic reviews focused on screening for CKD are rare, and the issues about microalbuminuria screening in the general population have never been reviewed. We systematically reviewed studies regarding ...

We investigated the role of 1-deoxynojirimycin (DNJ) on glucose absorption and metabolism in normal and diabetic mice. Oral and intravenous glucose tolerance tests and labeled (13)C6-glucose uptake assays suggested that DNJ inhibited intestinal glucose absorption in intestine. We also showed that DNJ down-regulated intestinal SGLT1, Na(+)/K(+)-ATP and GLUT2 mRNA and ...

Dead organic matter (OM) is a major source of nitrogen (N) for plants. The majority of plants support N uptake by symbiosis with arbuscular mycorrhizal (AM) fungi. Mineralization of N is regulated by microfauna, in particular, protozoa grazing on bacteria. We hypothesized that AM fungi and protozoa interactively facilitate plant ...

Joint damage from bleeding episodes leads to physical or functional limitations in people with haemophilia. Various factors may influence the frequency and severity of joint damage. This study examined whether age, prophylaxis, history of high-titre inhibitors (HTI) and bleeding events influenced the Haemophilia Joint Health Score (HJHS) in children. Medical ...

A three-component reaction has been developed that allows the regioselective synthesis of thieno[2,3-c]pyrroles. The reaction is based on the ability of 2-acetyl-3-thiophenecarboxaldehyde to react with amine and thiol nucleophiles to produce the corresponding tri-substituted thieno[2,3-c]pyrroles, with water as the only by-product. The developed reaction expands the range of synthetically accessible, ...

Vascular function is an important pathophysiological factor in cardiovascular disease, and is influenced by many factors, one of the principles being hypertension. Developing evidence suggests that inflammation may be another risk factor. Vascular function and blood pressure haemodynamics can be assessed by arterial stiffness, pulse pressure and plasma markers. Testing ...
