A new series of photoactive metallocyclodextrins with increased fluorescence intensity upon binding with ssDNAs/aptamers has been demonstrated to sensitively and selectively detect lysozyme. The detection mechanism relies on the formation of an aptamer-lysozyme complex, which leads to reduction of fluorescence intensity.

BACKGROUND A significant association has been identified between physical activity and proximity to greenways. However, residents more likely to be active may have selected to live near existing greenways. The purpose of this study was to determine whether development of a new greenway has the potential to increase activity levels of existing, proximate residents. METHODS In 2008, survey data...

In June, 6.7% of adult Succinea ovalis collected near Urbana, Ohio, were infected with the trematode, Leucochloridium variae. The effects of parasitism were assessed as total organic carbon (equivalent to calorific values) and as total nitrogen. The parasite represents 23.8% of total (parasite + snail tissue) dry tissue weight, 21.4% of total carbon and 19.8% of total nitrogen of infected snail...

Introduction The possible complications of transseptal puncture occur in approximately 1% of procedures. In the electrophysiology setting, increased pericardial effusion or tamponade risk is associated with left-sided arrhythmia ablations. Reported complications relate to aortic puncture or left/right atrial free wall perforation. There is much anatomical variation in the intra-atrial septum an...

In previous studies, the Alfin1 gene, a transcription factor, enhanced salt tolerance in alfalfa, primarily through altering gene expression levels in the root. Here, we examined the molecular evolution of the Alfin-like (AL) proteins in two Arabidopsis species (A. lyrata and A. thaliana) and a salt-tolerant close relative Thellungiella halophila. These AL-like proteins could be divided into fo...

A 56-year-old man had a 6 x 5-cm mass originating from the fossa ovalis in the atrial septum found by echocardiography and multiple enlarging scalp masses. The mass had a regular surface and was prolapsing into the mitral valve during diastole. The tumor was successfully treated by surgical excision, which revealed a well-defined mass with a narrow-base stalk originating from the fossa ovalis i...

Transseptal puncture (TSP) is a frequently performed procedure for gaining access to the left atrium for catheter ablation, hemodynamic assessment of the left heart, left ventricular assist device implantation, percutaneous left atrial appendage closure or mitral valvuloplasty during childhood and adulthood. The standard technique for transseptal puncture applies mechanical pressure on the foss...

The coral holobiont often resides in oligotrophic waters; both coral cells and their symbiotic dinoflagellates possess ammonium assimilation enzymes and potentially benefit from the nitrogen fixation of coral-associated diazotrophs. However, the seasonal dynamics of coral-associated diazotrophs are not well characterized. Here, the seasonal variations of diazotrophic communities associated with...

BACKGROUND Interaction between wave fronts in the right and left atrium may be important for maintenance of atrial fibrillation, but little is known about electrophysiological properties and preferential routes of transseptal conduction. METHODS AND RESULTS Eighteen patients (age 44+/-12 years) without structural heart disease underwent right atrial electroanatomic mapping during pacing from ...
