Dyson's conjecture, already proved by Gunson, Wilson and Good, is given a direct com-binatorial proof. We are going to give a combinatorial proof of [Z). The CCVlStUnt term Of n,&i+jcn (1-XJXj)+ iS This conjecture was proved by Gunson [S], Wilson [IO] and Good [5]. Recently Andrews [l] and MacDonald [7] formulated certain generalizations of conjecture which are still open. Andrews conjectured a...

Determinants of invasion and metastasis in cancer remain of great interest to define. Here, we report the definition of miR-339-3p as a novel tumor suppressive microRNA that blocks melanoma cell invasion without affecting cell survival. miR-339-3p was identified by a comprehensive functional screen of a human miRNA mimetic library in a cell-based assay for invasion by the melanoma cell line A37...

Previous studies conducted in our laboratory with Sindbis viral vectors in animal models demonstrated excellent in vivo targeting of tumor cells and significant reduction of metastatic implant size. To explore the influence of Sindbis strain on these factors, we constructed new plasmids from the wild-type Ar-339 Sindbis virus strain and compared their sequences. We found differences in the repl...

Objective. To evaluate primary care reform (PCR) in Barcelona during the year 2000 using 3 preventive practices: anti-smoking advice, blood pressure measurement, and flu vaccination. Any inequalities of gender, age, or social class in receiving these practices are also assessed. Design. Cross-sectional, descriptive, observational study. Setting. Barcelona Health Survey, primary health care, Spa...

Tumor suppressor p53 plays a central role in tumor suppression. To ensure its proper function, the levels and activity of p53 are under a tight regulation in cells. MicroRNAs are short non-coding RNAs that play an important role in regulation of gene expression. Recently, microRNA-339-5p has been reported to be frequently down-regulated in colorectal cancer, and furthermore, its down-regulation...

The aim of the present study was to investigate the potential role of microRNA (miRNA or miR) in invasion and metastasis of non-small cell lung cancer (NSCLC). miRNA-microarray analysis was used to detect the differentially expressed miRNAs between various metastatic levels of NSCLC cells. The microarray results were verified by quantitative polymerase chain reaction. The most clearly altered m...

Aim of this paper is to show the way of reasoning basing on the incomplete information about the initial state. The article presents an algorithm created in order to reason the state of scene from block world basing on incomplete information from two cameras observing the scene from top and side. The algorithm is explained using an example. Additionally, possible types of uncertainties are pres...

The mutual information is useful measure of a random vector component dependence. It is important in many technical applications. The estimation methods are often based on the well known relation between the mutual information and the appropriate entropies. In 1999 Darbellay and Vajda [3] proposed a direct estimation methods. In this paper we compare some available estimation methods using diff...
