BACKGROUND AND PURPOSE To investigate the feasibility of direct magnetic resonance portal vein thrombosis (PVT) visualization with T2*-weighted imaging (T2*WI) without contrast agent. METHODS Thirty patients with PVT were included in this study. All of them were imaged with contrast-enhanced CT (CE-CT) as well as non-contrast MRI T1, T2 and T2*WI. Imaging data was independently analyzed by tw...

We would like to comment on the recent article entitled “Stuck aortic valve treated by reteplase in a Bentall patient.” published in Anatol J Cardiol 2015; 15: 339-40 by Tanyeli et al. (1), in which the use of reteplase in a patient with a stuck aortic mechanical valve is reported. We believe there are some major drawbacks to be addressed regarding the diagnostic algorithm and the treatment of ...

In this paper, supply, process & temperature compensated, low voltage current reference for CMOS integrated circuits is presented. To minimize production cost, it uses no BJTs, external components or trimming procedures. This circuit is designed in Intel-22nm process and evaluated by computer simulations. The circuit behaviour is supported by theoretical expressions and is in agreement with sim...

On the basis of the analysis of PVT solution methods for navigation message, the solution procedure of evaluation algorithm of LSM and Kaman filtering evaluation algorithm is constructed. Further, based on OEM development board for data acquisition, PVT solution process of collected GPS signals is simulated, and the results show that the solution property of Kaman filtering algorithm is much be...

BACKGROUND/AIMS Portal-vein thrombosis (PVT) develops in 10-25% of cirrhotic patients and may aggravate portal hypertension. There are few data regarding the effects of anticoagulation on nonmalignant PVT in liver cirrhosis. The aim of this study was to elucidate the safety, efficacy, and predictors of response to anticoagulation therapy in cirrhotic patients. METHODS Patients with liver cirr...

The recent high-performance interfaces like DDR2, DDR3, USB and Serial ATA require their output drivers to provide a minimum variation of rise and fall times over Process, Voltage, and Temperature (PVT) and output load variations. As the interface speed grows up, the output drivers have been important component for high quality signal integrity, because the output voltage levels and slew rate a...

Background In the context of cirrhosis, portal vein thrombosis (PVT) is present in 2.1% to 26% of patients. PVT is no longer considered an absolute contraindication for liver transplantation, and nowadays, surgical strategies depend on the extent of PVT. Complete PVT is associated with higher morbidity rates and poor prognosis, while comparable long-term outcomes can be achieved as long as phys...

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...

We read with great interest the article published in Anatolian Journal of Cardiology by Astarcıoğlu et al. (1) entitled “ABO blood types: impact on development of prosthetic mechanical valve thrombosis.” Several risk factors of prosthetic valve thrombosis (PVT) are well known. The search for new categories of risks should continue to refine even more the initial therapeutic decision in PVT. In ...

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 ...
