The binarization of consensus partition matrices (Bi-CoPaM) method has, among its unique features, the ability to perform ensemble clustering over the same set of genes from multiple microarray datasets by using various clustering methods in order to generate tunable tight clusters. Therefore, we have used the Bi-CoPaM method to the most synchronized 500 cell-cycle-regulated yeast genes from different microarray datasets to produce four tight, specific and exclusive clusters of co-expressed genes. We found 19 genes formed the tightest of the four clusters and this included the gene CMR1/YDL156W, which was an uncharacterized gene at the time of our investigations. Two very recent proteomic and biochemical studies have independently revealed many facets of CMR1 protein, although the precise functions of the protein remain to be elucidated. Our computational results complement these biological results and add more evidence to their recent findings of CMR1 as potentially participating in many of the DNA-metabolism processes such as replication, repair and transcription. Interestingly, our results demonstrate the close co-expressions of CMR1 and the replication protein A (RPA), the cohesion complex and the DNA polymerases α , δ and ɛ , as well as suggest functional relationships between CMR1 and the respective proteins. In addition, the analysis provides further substantial evidence that the expression of the CMR1 gene could be regulated by the MBF complex. In summary, the application of a novel analytic technique in large biological datasets has provided supporting evidence for a gene of previously unknown function, further hypotheses to test, and a more general demonstration of the value of sophisticated methods to explore new large datasets now so readily generated in biological experiments.

Despite the undisputed importance of altered microRNA (miRNA) expression in various cancers, there is limited information on the clinicopathologic significance of cancer-related miRNAs in esophageal squamous cell carcinoma (ESCC). Previously, it was reported that the expression of several miRNAs was dysregulated in ESCC. However, the target genes of these miRNAs have not been identified. Furthermore, additional miRNAs in humans have been discovered recently, indicating that revised miRNA and gene expression profiling for ESCC are necessary. Here, we provide datasets from microarray analyses to identify miRNA and mRNA expression comprehensively in Het-1A, a normal human esophageal squamous cell line, and three human ESCC cell lines.

This article explores the spatial dynamics of agrofuels. Building on categories from the field of critical spatial theory, it shows how these categories enable a comprehensive analysis of the spatial dynamics of agrofuels that links the macro-structures of the global political economy to concrete, place-based struggles. Four core socio-spatial dynamics of agrofuel politics are highlighted and applied to empirical findings: territorialization, the financial sector as a new scale of regulation, place-based struggles and transnational spaces of resources and capital flows.

Purpose. The purpose of the work is to analyze the application of the second and third parts of Article 3692 of the Criminal Code of Ukraine to officials in the context, that defines them by the Criminal Code of Ukraine in the note to Article 364 of the Criminal Code of Ukraine. Methodology. The methodology includes a comprehensive analysis and synthesis of the available scientific and theoretical material and the formulation of relevant conclusions and recommendations. In the course of the study, the following methods of scientific knowledge were used: terminological, logical-semantic, system-structural, logical-normative. Results: in the course of research the cause of criminalization of such act as "abuse of power" is considered, the subject of the specified criminal act which has the features of "an official" in the context, that defines it by the note to Article 364 of the Criminal Code of Ukraine is analyzed and the main ways of committing criminal acts, that are provided for in this article of the Criminal Code of Ukraine are identified. Originality. The study found, that one of the key conditions for the opportunity to influence officials, that are authorized to perform government or local self-government functions, is the position held by the official and the related opportunities. Therefore, taking into account the opinion of the scientists, that the subject of crimes, that are provided for by the second and third parts of Article 3692 is special, the peculiarities of which is the cumulative feature, that denotes, that such person is not endowed with the status of an official, well-founded need to specify the criminal legislation of Ukraine in terms of the application the second and third parts of Article 3692 of the Criminal code of Ukraine concerning officials in the context, that defines them by the criminal legislation of Ukraine in the note to Article 364 of the Criminal Code of Ukraine. Practical significance. The research results can be used in lawmaking in the improvement of anti-corruption legislation.

Purpose. The purpose of the article is the regulation of relations on the principles of civil law. Methodology. The methodology includes a comprehensive analysis and a synthesis of available scientific and theoretical information. It is includes the formulation of relevant conclusions and recommendations. Such methods of scientific knowledge were used: terminological, functional, systemic-structural, logical-normative. Results: it was determined, that principles of civil law – an ideas of the civil law, that characterized by systematic,versatile, more stable, more regylated. Originality. An article is the special reseach that explores the problems of civil law in Ukraine. Practical significance. The results of the research can be used in legislation and law-enforcement activities.

Currently in Indonesia Islamic Bank has gained a place and interested in the community, causing many emerging Syari'ah Bank and Financial Institutions of the syari'ah, and products in Islamic banks are widely used is murabahah financing. The formulation of the problem in this research are: (1). How is the implementation of the sale and purchase through murabahah financing between Bank Muamalat Harkat with customers. (2). Is trading system murabahah financing between Bank Muamalat Harkat and customers have been according to the principles of Syari’ah. (3). How murabahah financing efforts to resolve the breach between the customer and Muamalat Harkat. This research method is empirical legal research, this study was conducted in Bank Muamalat Harkat based data collection through field research such as interviews, observation and description as well as information from respondents through library research. The results of this research are: before an agreement Bank to assess carefully the prospective customer in the form of a comprehensive analysis and is divided into several stages, such as the assessment using the principle of 5C Character (Character of the debitor), Chapacity (Capability Candidate Debitor) , Capital (Capital candidate Debitor), Collateral (Collateral candidate Debitor) and Condition of economy (economic condition of the prospective Borrower). Trading system murabahah financing between Bank Muamalat Harkat with the customer has not fully based on the principles of the Syari'ah. Murabahah financing efforts to resolve the defaults can be solved by R3 is Restrukturing (Arrangement Back), Reconditioning (Terms Back) and Rescheduling (rescheduling), sales collateral and auction execution.
