BACKGROUND Color Doppler sonography indices, such as resistive index (RI) and pulsatility index (PI), can predict arteriosclerosis of internal renal vessels after kidney transplantation. Angiotensin II receptor antagonists, however, may have antiatherogenic effects. We therefore assessed the effects of losartan on RIs of renal allografts. METHODS We compared duplex sonographic measurements in...

Reference values are used to describe the dispersion of variables in healthy individuals. They are usually reported as population-based reference intervals (RIs) comprising 95% of the healthy population. International recommendations state the preferred method as a priori nonparametric determination from at least 120 reference individuals, but acceptable alternative methods include transference...

Background and objectives: Humulus lupulus, a plant belonging to the family Cannabaceae, is used as a medicinal plant with therapeutic applications in different nations. In this study, two samples of H. lupulus (vernalized and wild hops) were selected for further analysis about differences of their essential oils. Methods: The essential oils f...

The technique of resonance ionization spectroscopy (RIS), makes use of the resonant absorption of photons via allowed electronic transitions to transfer an electron in a neutral gaseous atom (or molecule) from some initial state through various excited states to the continuum. This process can be elementally, even isotopically, selective. The product is an ion pair, and either the electron or t...

We studied the junctional region between rod inner segments (RIS) and outer segments (ROS) in frog retinas by high resolution scanning electron microscopy (SEM). Retinas of dark adapted or light exposed Rana pipiens were critical-point-dried and RIS and ROS were split and coated with ultrathin metal films of niobium and chromium--or decorated with gold--and imaged in a new SE-I imaging mode. Th...

INTRODUCTION Laboratories are recommended to determine their own local reference intervals (RIs) to embrace the variations in local populations. We have assessed local RIs for thyroid function tests using two different approaches to selection of reference populations and also searched the literature for studies using the Advia Centaur methods. METHODS Two independent populations were made of ...

This study concerns the presence and status of Tense in young children’s nonfinite main clauses, or root infinitivals (RIs). Verb-containing utterances produced by four Dutch-speaking boys (age range 1;9 3;2) were classified along the following dimensions: finite infinitive; temporal reference, as indicated by linguistic and non-linguistic context; and type of verb: eventive vs. non-eventive. T...

PURPOSE The authors evaluated the relationships between the clinical factors and resistive indexes (RIs) of prostate and urethral blood flows by using power Doppler transrectal ultrasonography (PDUS) in men with benign prostatic hyperplasia (BPH). METHODS The data of 110 patients with BPH and lower urinary tract symptoms (LUTS) treated between January 2015 and July 2015 were prospectively col...
