There are few reliable markers for assessing traumatic brain injury (TBI). Elevated levels of oxidative stress have been observed in TBI patients. We hypothesized that oxidation-reduction potential (ORP) could be a potent biomarker in TBI. Two types of ORP were measured in patient plasma samples: the static state of oxidative stress (sORP) and capacity for induced oxidative stress (icORP). Diff...

PURPOSE Given the lack of randomized trials comparing robot-assisted radical prostatectomy (RARP) and open radical prostatectomy (ORP), we sought to re-examine the outcomes of these techniques using a cohort of patients treated in the postdissemination era. PATIENTS AND METHODS Overall, data from 5,915 patients with prostate cancer treated with RARP or ORP within the SEER-Medicare linked data...

It is well known that the presence of nodes using a low data transmit rate has a disproportionate impact on the performance of an IEEE 802.11 WLAN. ORP is an opportunistic relay protocol that allows nodes to increase their effective transmit rate by replacing a low data rate transmission with a two-hop sequence of shorter range, higher data rate transmissions, using an intermediate node as a re...

The use of pH and oxidation-reduction potential (ORP) as control parameters for the nitrificationdenitrification process is compared and discussed. The signals were measured in a sequencing batch reactor activated sludge system and in a completely mixed activated sludge reactor. The termination of denitrification was clearly identified not only by an ORP signal, but also by a pH signal. However...

INTRODUCTION The utility of multiple sleep latency tests (MSLTs) is limited to determining sleep onset latency (SOL) and rapid eye movement sleep latency. The odds ratio product (ORP) is a continuous index of sleep depth with values of 0, 1.0, and 2.5 reflecting very deep sleep, light sleep, and full wakefulness, respectively. We determined the time course of sleep depth during MSLT naps expect...

Rendezvous is a fundamental process in the operation of a Cognitive Radio Network (CRN), through which a secondary user can establish a link to communicate with neighbors on the same frequency band (channel). The licensed spectrum is supposed to be divided into N non-overlapping channels and most previous works assume all users have the same label for the same channel. However, this might be im...

PURPOSE We compared the impact of prostate volume on oncological and functional outcomes 2 years after robot-assisted laparoscopic prostatectomy (RALP) and open radical retropubic prostatectomy (ORP). MATERIALS AND METHODS Between 2003 and 2010, 253 consecutive patients who had undergone prostatectomy by a single surgeon were serially followed over 2 years postoperatively. RALP was performed ...

Biomarkers for the early detection of liver toxicity are crucial in drug development for assessing the safety of a new drug. Oxidation reduction potential (ORP) is an overall measure of the oxidative stress to which a biological component is subjected and correlates with organ dysfunction. Raman spectroscopy is a non-invasive method that we employed to analyze the perfusates of five normothermi...

ORP150 is a hypoxic stress-induced protein located in the endoplasmic reticulum. Transgenic mice overexpressing ORP150 (ORP-Tg) exhibit vacuolar degeneration in the heart. To determine whether vacuolization is present in skeletal muscle, we pathologically examined ORP-Tg mice. After 60 days of age, severe vacuolization was found in the soleus muscles of the hind legs of the ORP-Tg mice. Immunoh...

NOx removal from a smoke tube boiler flue gas was investigated using a commercial ozonizer for indirect NO oxidation and a Na2SO3 chemical scrubber. The flue gas flow rate was in the range of 410 Nm/h-1480 Nm/h, the gas temperature of 185 °C-325 °C, and NOx concentration of around 40 ppm in city gas firing. Operational and performance data were obtained. The NOx removal efficiency was clearly d...
