The paraventricular nucleus of the thalamus (PVT) sends a very dense projection to the nucleus accumbens. This area of the striatum plays a key role in motivation and recent experimental evidence indicates that the PVT may have a similar function. It is well known that a dopaminergic projection from the ventral tegmental area (VTA) to the nucleus accumbens is a key regulator of motivation and r...

The thalamus is a major relay and integration station in the central nervous system. While there is a large body of information on the firing and network properties of neurons contained within sensory thalamic nuclei, less is known about the neurons located in midline thalamic nuclei, which are thought to modulate arousal and homeostasis. One midline nucleus that has been implicated in mediatin...

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 describe the behavior of hemostatic variables in children with portal vein thrombosis (PVT) and in a control pediatric population. Hereditary protein C (PC) or protein S (PS) deficiency was not a etiologic factor for PVT in children. Minor signs of consumption of coagulation factors II, V, fibrinogen and hyperfibrinolysis were detected. One child had lupus anticoagulant (LA).

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...
