Protargol staining is a crucial method to reveal the infraciliature of ciliates, which is the most important morphological character for species identification. In the present study, Wilbert's protocol of protargol staining was emended mainly towards the highly happened improper bleaching. Through reciprocal treatments, both insufficient and excessive bleachings were much eliminated from the protargol protocol and the tests performed with four different species of ciliates established that the stainings were considerably improved and more reliable with optimized bleaching...

PURPOSE: Catheter ablation is performed under fluoroscopic guidance. Reduction of radiation dose for patients and staff is emphasized by current recommendations. Previous studies have shown that lower operator experience leads to increased radiation dose. On the other hand, less experienced operators may depend even more on fluoroscopic guidance. Our study aimed to evaluate feasibility and efficacy of a non-fluoroscopic approach in different training levels. METHODS: From January 2017, a near-zero fluoroscopy approach was established in two centers...

Although regular physical activity is known to benefit health of aging populations, there are still many factors, which regulate exercise-induced adaptive changes. Among many vitamin D and myokines are under consideration. We, therefore, evaluated the influence of a single session of and regular Nordic Walking (NW) training combined with vitamin D supplementation on cognitive functions and muscle strength and some elements of the amino-acid profile. Thirty-five healthy elderly women (68 ± 5 years old) from health promotion programmes took part in the study...

To determine boron quantity in soil, water and biological samples, several protocols are available. Colorimetric assays are the simplest and cheapest methods which can be used to determine boron concentration. However, published protocols do not give straightforward guidance for beginners to adopt these protocols for routine use in the laboratory. Based on a previously published available procedure, we present a detailed and modified version of a curcumin based colorimetric protocol to determine boron concentration extracted from any sample...

BACKGROUND: Formulift is a newly developed mobile health (mHealth) app that connects to a single inertial measurement unit (IMU) worn on the left thigh. The IMU captures users' movements as they exercise, and the app analyzes the data to count repetitions in real time and classify users' exercise technique. The app also offers feedback and guidance to users on exercising safely and effectively. OBJECTIVE: The aim of this study was to assess the Formulift system with three different and realistic types of potential users (beginner gym-goers, experienced gym-goers, and qualified strength and conditioning [S&C] coaches) under a number of categories: (1) usability, (2) functionality, (3) the perceived impact of the system, and (4) the subjective quality of the system...

Early parental nutritional interventions during prenatal development have been shown to result in neuropsychiatric sequelae in the adult offspring. In order to understand the impact of such nutritional interventions, the behavior of the animal has to be carefully analyzed. This chapter provides a step-by-step guide to conduct behavioral tests in adult mice for investigators without specific expertise or those without the equipment to carry out behavioral studies. We focus on tests tapping into the main behavioral abnormalities that correspond to mental illnesses...
