Salvage radiotherapy (SRT) has been successfully used for recurrent prostate cancer after radical prostatectomy; however, the optimal timing of SRT remains controversial. Our objective was to identify the risk factors for disease progression after SRT, with a focus on the pre-SRT prostate-specific antigen (PSA) levels in the modern era of PSA testing. We performed a retrospective review of 551 ...

Simple reaction time (SRT), the latency to respond to a stimulus, has been widely used as a basic measure of processing speed. In the current experiments, we examined clinically-relevant properties of a new SRT test that presents visual stimuli to the left or right hemifield at varying stimulus onset asynchronies (SOAs). Experiment 1 examined test-retest reliability in 48 participants who under...

Simple reaction time (SRT), the minimal time needed to respond to a stimulus, is a basic measure of processing speed. SRTs were first measured by Francis Galton in the 19th century, who reported visual SRT latencies below 190 ms in young subjects. However, recent large-scale studies have reported substantially increased SRT latencies that differ markedly in different laboratories, in part due t...

Purpose. This study evaluates functional changes in electroretinographic findings after selective retina therapy (SRT) compared to panretinal photocoagulation (PRP) in rabbits. Methods. The right eyes of 12 Chinchilla rabbits received 200 laser treatment spots. The right eyes of six rabbits received SRT (SRT group), whereas the other six animals were treated using PRP on the right eye (PRP grou...

Human memory systems have been divided into two broad domains, one responsible for ‘declarative memory’ and the other for ‘non-declarative memory’. The evidence for multiple memory systems is reviewed with respect to the human SRT, a sensitive measure of non-declarative memory. A qualitative review of the human SRT literature concludes that damage to extrapyramidal brain systems disrupts SRT pe...

Background: This study was designed to suggest the possibility of hormone-related derangement in salvage radiotherapy (SRT) after radical prostatectomy in terms of prostate-specific antigen (PSA) control. Materials and Methods: Among 160 consecutive prostate cancer patients who received radical prostatectomy, 34 with SRT between 2004 and 2012 were retrospectively reviewed. The numbers of patien...

Two experiments investigated the effects of system response time (SRT) on navigating through hypertext. SRT duration was varied systematically and manipulated between subjects. The dependent variables were residence time, emotional strain, and memory performance. All three variables were influenced by SRT. As a prominent result, a synchronization between computer’s and human’s response time was...

In this paper the cogency and relative strength of Einstein's Special Relativity Theory (SRT) are evaluated. Additionally, the conceptual framework of SRT is reviewed in some detail. This exposition may also serve as a brief review of the criticism that has been directed against SRT during the second half of the last century.

The aim of this study is the methodology of optimal choice of firefighters to solve difficult rescue tasks. 27 firefighters were analyzed: aged from 22-50 years of age, and with 2-27 years of work experience. Body balance disturbance tolerance skills (BBDTS) measured by the 'Rotational Test' (RT) and time of transition (back and forth) on a 4 meter beam located 3 meters above the ground, was th...

PURPOSE Older patients with newly diagnosed glioblastoma have poor outcomes, and optimal treatment is controversial. Hypofractionated radiation therapy (HRT) is frequently used but has not been compared to patients receiving standard fractionated radiation therapy (SRT) and temozolomide (TMZ). METHODS AND MATERIALS We conducted a retrospective analysis of patients ≥65 years of age who receive...
