The choice treatment for choledocholithiasis when associated with lithiasic cholecystitis is endoscopic retrograde cholangiopancreatography (ERCP). However, in some cases this therapeutic fails, which requires an alternative method to extract the stones. The surgical approach tends to be the next step, but it is related to greater complexity of achievement and higher complications rates. In 1993, Deslandres et al. developed the combined treatment called laparoendoscopic rendez-vous, that unites in a single stage the endoscopic treatment of choledocholithiasis and laparoscopic removal of the gallbladder...

INTRODUCTION: Complete primary repair of bladder exstrophy (CPRE) is widely used for classic bladder exstrophy (CBE) closure. Long-term renal function with or without dilation in these patients is poorly characterized and may be impacted by bladder storage parameters or recurrent urinary tract infections (UTIs). OBJECTIVE: We sought to assess our long-term experience with CPRE and investigate factors that may influence upper-tract deterioration. STUDY DESIGN: A retrospective review of patients at our institution with CBE undergoing CPRE from 1990 to 2015 was performed...

PURPOSE: Ratings of perceived exertion (RPE) may be useful for exercise testing and prescription in individuals with spinal cord injury (SCI), though the roles of differentiated central and peripheral fatigue during exercise are not clear. We aimed to model differentiated RPE responses during graded arm cycling in individuals with SCI and describe their relationship to cardiorespiratory outcomes. METHODS: Thirty-six individuals with SCI (13 paraplegia; 23 tetraplegia) completed a maximal graded-arm cycling exercise test to volitional exhaustion (5W/min paraplegia; 10W/min tetraplegia)...

Our objectives were to establish a methodology for surveillance of ciprofloxacin-resistant Enterobacteriaceae and gentamicin-resistant Enterobacteriaceae (CPRE and GNRE, respectively) in cattle and to study the prevalence and risk factors for carriage of these bacteria in a national survey. This was a point prevalence study conducted from July to October 2013 in Israel. Stool samples were collected from 1,226 cows in 123 sections of 40 farms of all production types. The number of CPRE- and GNRE-positive cows was highest in quarantine stations and fattening farms and was lowest in pasture farms (p < 0...

An array of complexes, (99m)Tc/Re-labeled cyclopentadienyl tricarbonyl and 2-phenyl/pyridylbenzothiazoles, conjugated through an ester linkage were tested as potential β-amyloid (Aβ) probes for SPECT imaging. The [CpRe/(99m)Tc(CO)3] complexes were prepared by double ligand transfer reactions from ferrocene precursors, and the X-ray structure of one rhenium surrogate revealed a classical "piano stool" like geometry. Several of the rhenium complexes displayed high affinity for Aβ1-42 aggregates in in vitro inhibition assays, and they could intensely stain Aβ deposits on brain sections from transgenic mice and Alzheimer's disease (AD) patients...

BACKGROUND: Over the last 400 years, cocoa and chocolate have been described as having potential medicinal value, being consumed as a beverage or eaten as food. Concentration-dependant, antiproliferation, and cytotoxic effects of some of their polyphenolic constituents have been demonstrated against various cancers. Such an effect remains to be demonstrated in ovarian cancer. OBJECTIVE: To investigate the effect of cocoa procyanidins against ovarian cancer in vitro using OAW42 and OVCAR3 cell lines...

INTRODUCTION: Long-term continence outcomes for patients with bladder exstrophy are lacking in the literature. The complete primary repair of exstrophy (CPRE) is a widely adopted approach that seeks to normalize anatomy at the initial repair, thereby allowing early bladder filling and cycling. Previous reports of continence following CPRE, however, are limited by variable follow-up duration and continence definitions. OBJECTIVE: To assess continence and factors associated with a positive outcome in a cohort of patients following CPRE with long-term follow-up...

BACKGROUND: Inguinal hernias are common in the bladder exstrophy population. As these hernias may present with incarceration following bladder closure, several groups recommend inguinal exploration and hernia repair at the time of initial bladder closure. However, the benefits of such an approach are not well defined. In 2006, we modified our approach to this condition by routinely performing concomitant inguinal herniorraphy (CIH) repair at the time of initial exstrophy repair. The aim of this study was to test the hypothesis that simultaneous inguinal hernia repair will be safe and effective in reducing subsequent unplanned inguinal procedures in this high-risk group...

In seeking to create more-stable transition metal-alkane complexes, we generated cationic alkane complexes of the type [(HEB)Re(CO)2(alkane)][Al(OR(f))4] (HEB = η(6)-hexaethylbenzene; alkane = cyclopentane (16) or pentane (17-19); OR(f) = perfluoro-tert-butoxy) via photolysis of the precursor complex [(HEB)Re(CO)3][Al(OR(f))4] (15) in the presence of the added alkane. The alkane complexes were generated in a hydrofluorocarbon (HFC) solvent, most often CF3CH2CF3, which is capable of simultaneously dissolving the ionic complex 15 and a small amount of alkane at low temperature (183 K)...

Both hyperphosphatemia and hypophosphatemia are associated with increased morbidity and mortality among patients on dialysis. The control of serum phosphate concentration is a considerable clinical problem. Our study aimed to improve understanding of phosphate kinetics in patients on dialysis using mathematical modeling. Three consecutive hemodialysis sessions with breaks of 2-2-3 days were monitored in 25 patients. Phosphate concentration was measured every hour and 45 min after the end of dialysis in blood serum and every 30 min in dialysate during each session...

INTRODUCTION/OBJECTIVE: Secure closure of the pubic diastasis during bladder exstrophy and epispadias repair decreases the abdominal wall tension at the time of reconstruction. Pelvic osteotomies are routinely performed at the time of abdominal wall and bladder reconstruction in order to more easily facilitate pubic symphyseal diastasis approximation. Postoperative pelvic immobilization is performed by methods that include modified Buck's traction, modified Bryant's traction, and spica casting...

AIMS: Post-exstrophy incontinence is a challenge because continence is difficult to achieve and more difficult to maintain. Feasibility and outcomes of a bulbourethral sling to treat post-exstrophy incontinence is shown in this report. METHODS: A retropubic bulbourethral sling was applied to male patients with incontinence post-exstrophy-epispadius repair. The study included children with total (continuous) incontinence who underwent multiple previous anti-incontinence procedures, ranging from bladder neck injection to bladder neck reconstruction...

Heavy-metal containing chiral compounds have been suggested as promising candidates for studying parity-violation effects. We report herein the broadband rotational spectroscopy study of the chiral complex [CpRe(CH3)(CO)(NO)] in the gas phase. The spectra obtained are very rich due to the two rhenium isotopologues ((185)Re and (187)Re), hyperfine structure arising from the rhenium and nitrogen nuclei, and the asymmetry of the chiral complex. Since rhenium is located very close to the molecular center of mass, the rotational constants for the two rhenium isotopologues are very similar...

To gain insight into thermodynamic barriers for reduction of CO into CH3OH, free energies for reduction of [CpRe(PPh3)(NO)(CO)](+) into CpRe(PPh3)(NO)(CH2OH) have been determined from experimental measurements. Using model complexes, the free energies for the transfer of H(+), H(-), and e(-) have been determined. A pKa of 10.6 was estimated for [CpRe(PPh3)(NO)(CHOH)](+) by measuring the pKa for the analogous [CpRe(PPh3)(NO)(CMeOH)](+). The hydride donor ability (ΔG°H(-)) of CpRe(PPh3)(NO)(CH2OH) was estimated to be 58...

Photolysis of CpRe(CO)3 in the presence of H3BNEt3 yields the trans-CpRe(CO)2(H)2 complex. This preliminary finding presents a rare example of transition metal mediated dehydrogenation of a tertiary amine-borane and suggests that the abstracted hydrogens may be stored in the form of metal hydride complexes.

OBECTIVES: Spinal cord ischaemia with resulting paraplegia remains a devastating and unpredictable complication after thoraco-abdominal aortic surgery. With the advent of stem cell therapy and its potential to induce nervous tissue regeneration processes, the interest in the use of these cells as a treatment for neurological disorders has increased. Human stem cells, derived from the umbilical cord, are one of the strong candidates used in cell therapy for spinal cord injury because of weak immunogenicity and ready availability...
