Neuropsychological tests are proliferating in Indonesia. So far, unfortunately, it is not accompanied by the development of a performance validity test (PVT). According to international neuropsychological standards, using PVTs essential determine results. To date, there no single standardized PVT available In this article, we describe (1) concept testing, (2) detection strategy, and (3) procedu...

Bias Temperature Instability (BTI) is a major reliability issue in Nano-scale CMOS circuits. BTI effect results in the threshold voltage increase of MOS devices over time. Given the Process, Voltage, and Temperature (PVT) dependence of BTI effect, and the significant amount of PVT variations in Nano-scale CMOS, we propose a method of combining the effects of PVT variations and the BTI effect fo...

Portal vein thrombosis (PVT) is commonly associated with liver cirrhosis, irrespective of the presence of hepatocellular carcinoma (HCC). Given that malignant PVT is a poor prognostic factor in patients with HCC, it is important to differentiate malignant PVT from benign PVT. Because malignant PVT has been reported to be contiguous with parenchymal HCC, in most cases, the presence of PVT alone ...

BACKGROUND & OBJECTIVES Discrepancies exist in the reported prevalence of portal vein thrombosis (PVT), and its clinical characteristics and sites of occurrence need to be elucidated. The risk factors for PVT are also poorly understood. This single centre study was undertaken to determine the clinical characteristics, sites of occurrence, and risk factors associated with PVT in patients with li...

The goal of the present study was to examine the effect of listening to self-relevant words (i.e., one's own name) on vigilant attention, arousal, and subjective sleepiness during performance of a psychomotor vigilance test (PVT). Twenty-one participants aged 20-26 years (22.2 ± 1.76) performed a PVT in four experimental conditions: one in which their own full name was pronounced every 20 s in ...

AIM The present study investigates the effect of combined treatment with Ginkgo biloba and/or Rhodiola rosea on psychomotor vigilance task (PVT) and short-term working memory accuracy. SUBJECTS AND METHODS A total number of 112 volunteers were enrolled to study the effect of G. biloba and R. rosea on PVT and short-term working memory accuracy as compared to placebo effects, the central cognit...

PURPOSE Portal vein thrombosis (PVT) has been considered a relative contraindication for living donor liver transplantation (LDLT). However, it is no longer a contraindication of LDLT due to improvement in surgical techniques and approaches to PVT. The aim of this study was to assess the impact of PVT on outcomes in LDLT patients. METHODS We retrospectively analyzed the data from 97 adult pat...

We have developed a new psychomotor vigilance test (PVT) metric for quantifying the effects of sleep loss on performance impairment. The new metric quantifies performance impairment by estimating the probability density of response times (RTs) in a PVT session, and then considering deviations of the density relative to that of a baseline-session density. Results from a controlled laboratory stu...

BACKGROUND Extra-hepatic portal vein obstruction due to portal vein thrombosis (PVT) is an important cause of portal hypertension in several regions including India. The cause of thrombosis in these patients remains unclear. We studied the frequency of mutations in genes for coagulation factors V and II (prothrombin) in 61 Indian patients with PVT and 49 healthy control subjects. METHODS The ...

BACKGROUND Live donor liver transplantation (LDLT) for patients with portal vein thrombosis (PVT) creates several technical challenges due to severe pre-operative condition and extensive collaterals. Although deceased donor liver transplantation in patients with PVT is now routinely performed at most centers, the impact of PVT on LDLT outcomes is still controversial. OBJECTIVE To determine th...
