Understanding the properties of electronically interacting molecular chromophores, which involve internally coupled electronic-vibrational motions, is important to the spectroscopy of many biologically relevant systems. Here we apply linear absorption, circular dichroism, and two-dimensional fluorescence spectroscopy to study the polarized collective excitations of excitonically coupled cyanine dimers (Cy3)2 that are rigidly positioned within the opposing sugar-phosphate backbones of the double-stranded region of a double-stranded (ds)-single-stranded (ss) DNA fork construct...

PURPOSE OF REVIEW: Significant variance exists in the management of duplex collecting system ureteroceles (DSU). There is a great spectrum in classification, management, and surgical interventions. The practice of performing bladder level operations for vesicoureteral reflux (VUR) and trigonal anatomic distortion, either after ureterocele puncture or in a single setting, has come into question as to whether all DSU patients require it. In this review, we sought to discuss DSU management trends and the need for bladder reconstruction in these patients, as well as to describe our institution's practices...

Quantitative PCR (qPCR) assay using TaqMan™ probe was widely used in the detection of different nucleic acids. However, this technology has several drawbacks, including false negative results caused by primer-dimer (PD) and false positive issues due to primer-probe aggregations. Here, we designed a modified TaqMan™-Molecular Beacon probe by adding an antisense base and a new type of primer pair named central-homo primer pairs bearing 5-10 bases homologous sequence on the 3' end. Using the HBV qPCR assay as a proof of concept, the new design significantly improved the accuracy of the TaqMan™ qPCR assay for HBV detection...

Bistrand lesions embedded within a single helical turn of tridecameric deoxyoligonucleotide duplexes represent a model system for exploring the impact of clustered lesions that occur in vivo and pose a significant challenge to cellular repair machineries. Such investigations are essential for understanding the forces that dictate lesion-induced mutagenesis, carcinogenesis, and cytotoxicity within a context that mimics local helical perturbations caused by an ionizing radiation event. This study characterizes the structural and energy profiles of DNA duplexes harboring synthetic abasic sites (tetrahydrofuran, F) as models of clustered bistrand abasic (AP) lesions...

Pelvic kidney is a relatively common renal malformation as well as duplex kidney; however, the unilateral coexistence of these abnormalities is not frequently found. We present a case of a young woman with a history of hypertension in whom a pelvic and dysmorphic left kidney was discovered during ultrasound examination performed for the study of the renal arteries. Magnetic resonance imaging and computed tomography imaging revealed a duplex pelvic kidney. This combination is very rare; we have not found a similar case reported in the literature...

INTRODUCTION: Duplex collecting system of the kidney is a relatively common abnormality, with the majority of symptomatic cases discovered in childhood. Treatment is commonly a heminephrectomy of the affected moiety. We aimed to conduct a systematic review of the literature to provide the best available evidence for heminephrectomy for duplex kidneys in the adult population. MATERIALS AND METHODS: A literature search was conducted in September 2017 with no limitations being placed on language, region, date or publication type...

Static apnea provides a unique model that combines transient hypertension, hypercapnia, and severe hypoxemia. With apnea durations exceeding 5 min, the purpose of the present study was to determine how that affects cerebral free-radical formation and the corresponding implications for brain structure and function. Measurements were obtained before and following a maximal apnea in 14 divers with transcerebral exchange kinetics, measured as the product of global cerebral blood flow (duplex ultrasound) and radial arterial to internal jugular venous concentration differences ( a-vD )...

Since the nature of the exosomal lipid bilayer can allow miRNAs to be protected from degradation by cellular RNAses in body fluids, exosomal microRNA (miRNA) has become an ideal source of non-invasive biomarkers for the early diagnosis and prognosis. In this paper, a new surface-enhanced Raman scattering (SERS) analysis strategy combining stable SERS reporter element and duplex-specific nuclease (DSN)-assisted signal amplification for quantitative detection of exosomal miRNA extracted from human blood is proposed...

Asthma is a chronic airway inflammation with a potential systemic impact. Atherosclerosis is a chronic inflammatory artery disease. The aim of our study was to prove if there is a correlation between the occurrence of asthma and increased atherosclerotic vessel disorders. Vessel status was compared between mild-to-moderate, severe allergic asthma and matched controls. Measurements of artery stiffness were calculated by central pulse wave velocity, ultrasonographic strain imaging and ankle-brachial index. Atherosclerotic plaque burden was assessed by colour-coded duplex sonography...

BACKGROUND: The majority of iliac venous obstructions occur on the left side, and endovascular therapy has become the first line treatment for this condition. A left common iliac venous stent will protrude into the inferior vena cava (IVC) to some extent, thereby covering the contralateral common iliac vein (CIV) outflow. This may increase the risk of thrombosis of the contralateral iliac vein. The aim of this paper was to determine the rate of, and factors associated with, contralateral lower limb venous thrombosis after stenting, and to evaluate the results of salvage revascularisation...

Atherosclerosis is a systemic disease with manifestations in multiple vascular beds. Ideal cardiovascular health (CVH) metrics relate to cardiovascular and cerebrovascular disease. However, the relation between ideal CVH metrics and asymptomatic polyvascular disease (polyVD) is unknown. We collected information on the 7 CVH metrics among 5,224 participants aged ≥40 years from 2010 to 2011. Intracranial artery stenosis, extracranial artery stenosis, and lower extremity artery disease were detected by transcranial Doppler, duplex sonography, and by calculating ankle-brachial index...

Lymphedema distichiasis syndrome (LDS) is a rare, autosomal dominant genetic condition, characterized by lower limb lymphedema and distichiasis. Other associated features that have been reported include varicose veins, cleft palate, congenital heart defects, and ptosis. We update a previously reported family with a pathogenic variant in FOXC2 (c.412-413insT) where five affected individuals from the youngest generation had congenital renal anomalies detected on prenatal ultrasound scan. These included four fetuses with hydronephrosis and one with bilateral renal agenesis...

Harmful cyanobacteria have been an important concern for drinking water quality for quite some time, as they may produce cyanotoxins and odorants. Microcystis and Cylindrospermopsis are two common harmful cyanobacterial genera detected in freshwater lakes and reservoirs, with microcystins (MCs) and cylindrospermopsin (CYN) as their important metabolites, respectively. In this study, two sets of duplex qPCR systems were developed, one for quantifying potentially-toxigenic Microcystis and Microcystis, and the other one for cylindrospermopsin-producing cyanobacteria and Cylindrospermopsis...

Most congenital anomalies of the kidney and urinary tract (CAKUT) are sporadic, but familial occurrence has been described, suggesting a genetic contribution. Copy‑number variations (CNVs) were detected in patients with CAKUT to identify possible novel genomic regions associated with CAKUT. CNVs were investigated in 7 children with CAKUT from three unrelated families using array comparative genomic hybridization: female monozygotic twins with bilateral duplex collecting system/vesicoureteral reflux (VUR)/unilateral renal hypodyspasia (URHD); two male siblings with VUR/URHD; 3 male second cousins, one with bilateral VUR/URHD, one with bilateral VUR and one with ureterovesical junction obstruction (UVJO)...

OBJECTIVE: Endothermal heat-induced thrombosis (EHIT) is a known complication of endothermal venous ablation procedures. EHIT can lead to deep vein thrombosis/pulmonary embolism, which cause significant disability and, rarely, death. Other studies have evaluated risk factors for EHIT. There is an accepted grading system for EHIT, but there is no consensus on treatment type, duration, or follow-up. We retrospectively evaluated all cases of EHIT after radiofrequency ablation or endovenous laser ablation at our institution during a 7-year period, focusing on classification, treatment, and outcomes of EHIT...
