Primary cardiac lymphoma (PCL) is a rare disorder, but the incidence is increasing and its clinical manifestations are various. We report a case of PCL, which mimics an acute coronary and aortic syndrome. A 51 year-old female was presented with chest pain radiating to the back. Her initial electrocardiogram revealed T wave inversion in the leads of V 5-6, II, III and aVF. Additionally, cardiac ...

In this paper modeling and queuing analysis of variable-bit-rate (VBR) MPEG coded video sources transmitted over B-ISDN networks are studied. A low pass version of the aggregate MPEG sequence is examined so that the network resources are analytically predicted. Based on this simplified signal, a discrete-state continuous-time Markov chain is proposed to approximate the MPEG video traffic. Then,...

We are using MPEG-4 technology to build applications to be used in real environments. One of these applications allows for teacher to send real-time lessons to this/her students or to record them. The TeleLearning System under development includes: a) on the teacher side: a recording workstation with two cameras, microphone, specific MPEG-4 software; b) an IP network or an MPEG-2 TS satellite l...

Thanks to the ever growing diffusion of distributed multimedia applications, VBR compressed video traffic is expected to constitute the majority of the B-ISDN network load in the immediate future. At the moment, the MPEG coding scheme is widely used for many types of applications. Therefore, it is crucial to obtain a model for the generation of sequences with the same statistical characteristic...

Primary cardiac lymphoma (PCL) is an extremely rare and fatal neoplasm of the heart. Traditionally, it is defined as lymphoma involving the heart or pericardium. PCL has a poor prognosis because of the diagnostic difficulty and its location. We present the case of a 48-year-old man who presented with pericardial effusion and diffuse cardiac wall thickening. We first suspected infiltrative heart...

Biocomposite scaffolds were fabricated by incorporation of nanobredigite (n-BD) into the polymer of poly(ε-caprolactone)-poly(ethyleneglycol)-poly(ε-caprolactone) (PCL-PEG-PCL). The results revealed that the addition of n-BD into PCL-PEG-PCL significantly improved water absorption, compressive strength, and degradability of the scaffolds of n-BD/PCL-PEG-PCL composite (n-BPC) compared with PCL-P...

Micelles derived from poly(ε-caprolactone) (PCL) poly(ethylene glycol)(PEG) diblock copolymers (HO-PCLn-b-PEG32-RX, R = -O(CH2)3S(CH2)2-; X = -CO2(-), -SO3(-), -NH3(+)) show corona charge selective degradation catalyzed by P. cepacia lipase isoforms.

background: host immune system response against blood group antigens is a major problem in blood transfusions, especially forthalassemic patients. thus, an approach was proposed coating the red blood cell (rbc) surface by polyethylene glycol.objectives: this study aimed to obtain the optimal simultaneous camouflge of the major and minor antigens by activated methoxypolyethylene glycol (mpeg) wi...
