In this paper, a frequency-variation based method has been proposed for transistor parameter estimation in a commonemitter transistor amplifier circuit. We design an algorithm to estimate the transistor parameters, based on noisy measurements of the output voltage when the input voltage is a sine wave of variable frequency and constant amplitude. The common emitter amplifier circuit has been mo...

In the United States it is estimated that 20 million people have gallstones. An estimated 5.5 million of them have gallstones in the United Unido [1]. The first description of bile duct stones in humans was made by Alexander of Tralles (525-605 AD). However, it is ...

The Epstein-Barr virus (EBV) EBER transcripts are small, highly structured RNAs able to bind to and inhibit activation of the double-stranded RNA-dependent protein kinase PKR in cell-free systems, and within latently infected B-cell lines they inhibit alpha interferon-induced apoptosis that is believed to be mediated through PKR. Here, we address the consequences of EBER expression for PKR acti...

Even though brass, a zinc-copper alloy, had been known for centuries, metallic zinc was not isolated in Europe until 1509. The metal was then named zinken because of its superficial similarity to tin (German-zinn) (Wootton, 1910). Zinc (atomic number 30; atomic weight 65 37) has a completed d subshell with 2 s electrons and the divalent cation is the only naturally occurring oxidation state. Th...

Introduction: Epstein-Barr virus-positive DLBCL (EBV+ DLBCL) was defined by the WHO, with >80% EBERs+ cells, although 20% used as cut off. The detection of traces EBV reported more sensitive methods than EBERs in situ hybridization (ISH). aim to analyze immune response markers EBV+ DLBCL, and compare them cases or without infection. Methods: Fifty DLCBL were studied ISH. expression genes evalua...

To the Editor: The recent letter by Olson et al. (1) on the plague of Athens and the “reemergence (?)” of Ebola virus prompts brief reiteration of an earlier communication (2) placing human immunodeficiency virus (HIV) back in history, possibly in the time of the pharaohs. Translations of the Papyrus Ebers from ancient Egyptian literature repeatedly make reference to difficulties in the diagnos...

We have demonstrated that Epstein-Barr virus (EBV) confers enhanced growth capability in soft agarose, tumorigenesis in the SCID mouse, and resistance to apoptosis in the Burkitt's lymphoma cell line Akata. Subsequently, we have shown that EBV-encoded small RNAs (EBERs) are responsible for these phenotypes. We constantly observed the upregulation of bcl-2 oncoprotein expression upon EBV infecti...
