Background:Noncoding RNAs (ncRNAs) which play an important role in various cellular processes are important in medicine as well as in drug design strategies. Different studies have shown that ncRNAs are dis-regulated in cancer cells and play an important role in human tumorigenesis. Therefore, it is important to identify and predict such molecules by experimental and computational methods, respectively. However, to avoid expensive experimental methods, computational algorithms have been developed for accurately and fast prediction of ncRNAs.Objective:The aim of this review was to introduce the experimental and computational methods to identify and predict ncRNAs structure. Also, we explained the ncRNA’s roles in cellular processes and drugs design, briefly.Method:In this survey, we will introduce ncRNAs and their roles in biological and medicinal processes. Then, some important laboratory techniques will be studied to identify ncRNAs. Finally, the state-of-the-art models and algorithms will be introduced along with important tools and databases.Results:The results showed that the integration of experimental and computational approaches improves to identify ncRNAs. Moreover, the high accurate databases, algorithms and tools were compared to predict the ncRNAs.Conclusion:ncRNAs prediction is an exciting research field, but there are different difficulties. It requires accurate and reliable algorithms and tools. Also, it should be mentioned that computational costs of such algorithm including running time and usage memory are very important. Finally, some suggestions were presented to improve computational methods of ncRNAs gene and structural prediction.

<p>A matrix table of valence electron content of carbonyl clusters has been created using the 14n-based series. The numbers so generated form an array of series which conform precisely with valence electron contents of carbonyl clusters. The renowned 18 electron rule is a special case of 14n+4 series. Similarly, the 16 electron rule is another special case of the 14n+2 series. Categorization of the carbonyl clusters using the matrix table of series has been demonstrated. The table is so organized that clusters numerically represented can easily be compared and analyzed. The numbers that are diagonally arranged from right to left represent capping series. The row from right to left represents a decrease in valence electron content with increase in cluster linkages. The variation of cluster shapes of constant number of skeletal elements especially four or more may be monitored or compared with the variation with the valence electron content.</p>

Objective: The present study aims to outline the genotype of circulating CHIKV strains in Pakistan and their phylogenetic analysis Methods: The study is being conducted at Armed Forces Institute of Pathology after the approval by Institutional Review Board. The study was conducted during the period of Aug 2016 to Sep 2017. During this period we have got the total 11 suspected Chikungunya samples in our center and out of these 7 were positive. The viral RNA was extracted, amplified and then the purified product was sequenced by using Sanger dideoxy method. Structural Prediction and Analysis was performed by using Phyre2 and then models were visualized in PyMol2.2. Results: In our study total 11 samples were analyzed, in which 7 samples were positive and the amplified product from five samples were later sequenced because these samples were of good quality for sequencing. Phylogenetic tree was constructed. Five sequences generated in our study were aligned with other CHIKV sequences reported from all over the world. Conclusion: The phylogenetic analysis showed that the strains present in Pakistan belong to the ECSA genotype and derived from India and South East Asia. These results help in the better understanding of CHIKV evolution in the world and discovered that how CHIKV originated in Pakistan. Keywords: Chikungunya; glycoprotein E1; glycoprotein E2; Aedes aegypti. Continuous...
