Environmental microbial reservoir influences the bacterial communities associated with Hydra oligactis.

The objective to study the influence of microbiome on host fitness is frequently constrained by spatial and temporal variability of microbial communities. In particular, the environment serves as a dynamic reservoir of microbes that provides potential colonizers for animal microbiomes. In this study, we analyzed the microbiome of Hydra oligactis and corresponding water samples from 15 Hungarian lakes to reveal the contribution of environmental microbiota on host microbiome.

Arrhythmia Detection in Atrioventricular, Single-Lead, Floating Atrial Dipole ICD Systems Compared with Conventional Single- and Dual-Chamber Defibrillators.

Background: An atrioventricular defibrillator system with a floating atrial dipole (VDD ICD) can provide atrial sensing by a single lead. Our aim was to compare the arrhythmia detection efficacy of VDD ICDs with conventional single- (VVI) and dual-chamber (DDD) defibrillators.

Methods: Data from consecutive patients undergoing ICD implantation were retrospectively analyzed.

A Tutorial on the Applications of Lowenkron's Joint Control to Language Acquisition Programs.

Mediating one's behavior through covert or overt verbal behavior is a phenomenon familiar to anyone who has had to remember a phone number with no way to write it down, follow a recipe without consulting the cookbook for each step, or solve a math equation without a calculator or pencil and paper. Jointly controlled responding is a type of multiply controlled responding that may provide a behavioral analysis of such mediating responses. Joint control, as we will discuss in detail, involves one or more verbal responses bringing other verbal or nonverbal responses to strength under appropriate controlling conditions.

New Perspectives in Overcoming Bulk-Fill Composite Polymerization Shrinkage: The Impact of Curing Mode and Layering.

Background: The purpose of this study was to investigate the effect of different light curing modes on the polymerization shrinkage of a bulk-fill composite and to evaluate the impact of two layering techniques on the cuspal deflection.

Methods: Nine different light curing modes were tested on bulk-fill composite samples in aluminum MOD cavities. Intensity, duration, and illumination distance were the factors that changed during the different curing modes.

Risk of Cardiac Implantable Electronic Device Infection after Early versus Delayed Lead Repositioning.

(1) Background: Early reintervention increases the risk of infection of cardiac implantable electronic devices (CIEDs). Some operators therefore delay lead repositioning in the case of dislocation by weeks; however, there is no evidence to support this practice. The aim of our study was to evaluate the impact of the timing of reoperation on infection risk.
