Cardiorenal syndromes constellate primary dysfunction of either heart or kidney whereby one organ dysfunction leads to the dysfunction of another. The role of several microRNAs (miRNAs) has been implicated in number of diseases, including hypertension, heart failure, and kidney diseases. Wide range of miRNAs has been identified as ideal candidate biomarkers due to their stable expression. Current study was aimed to identify crucial miRNAs and their target genes associated with cardiorenal syndrome and to explore their interaction analysis. Three differentially expressed microRNAs (DEMs), namely, hsa-miR-4476, hsa-miR-345-3p, and hsa-miR-371a-5p, were obtained from GSE89699 and GSE87885 microRNA data sets, using R/GEO2R tools. Furthermore, literature mining resulted in the retrieval of 15 miRNAs from scientific research and review articles. The miRNAs-gene networks were constructed using miRNet (a Web platform of miRNA-centric network visual analytics). CytoHubba (Cytoscape plugin) was adopted to identify the modules and the top-ranked nodes in the network based on Degree centrality, Closeness centrality, Betweenness centrality, and Stress centrality. The overlapped miRNAs were further used in pathway enrichment analysis. We found that hsa-miR-21-5p was common in 8 pathways out of the top 10. Based on the degree, 5 miRNAs, namely, hsa-mir-122-5p, hsa-mir-222-3p, hsa-mir-21-5p, hsa-mir-146a-5p, and hsa-mir-29b-3p, are considered as key influencing nodes in a network. We suggest that the identified miRNAs and their target genes may have pathological relevance in cardiorenal syndrome (CRS) and may emerge as potential diagnostic biomarkers. [ABSTRACT FROM AUTHOR]

The population genetic structure and genetic diversity of Neolissochilus hexagonolepis were studied using three mitochondrial genes (CoxI, Cytb, ATPase 6/8). A total of 120 individuals representing nine populations from different drainages of Northeast India were used for the study. Thirty-three distinct haplotypes were identified from concatenated gene analysis. The total haplotype and nucleotide diversities are 0.8880 and 0.0280, respectively. The analysis of molecular variance (AMOVA) reveals that the main variation (89.33%) was among populations. Most of the populations showed high polymorphisms, parsimony and haplotype diversity which indicate genetically healthy stocks in the wild. The genetic differentiation patterns were consistent with geographical distributions. Pairwise FST comparison of populations showed significant genetic differentiation (0.9088, p <.05). The pattern of haplotype network and phylogenetic tree revealed six major groups. Results suggested that chocolate mahseer populations in Northeast India having high haplotype diversity and genetic differentiation can be utilized in breeding programs to maintain genetic diversity in the descendant populations. The present study would be beneficial for sustainable management, stock-specific strategies for breeding and conservation of the wild population of N. hexagonolepis in future. [ABSTRACT FROM AUTHOR]

The breast cancer network constructed from 70 experimentally verified genes is found to follow hierarchical scale free nature with heterogeneous modular organization and diverge leading hubs. The topological parameters (degree distributions, clustering co-efficient, connectivity and centralities) of this network obey fractal rules indicating absence of centrality lethality rule, and efficient communication among the components. From the network theoretical approach, we identified few key regulators out of large number of leading hubs, which are deeply rooted from top to down of the network, serve as backbone of the network, and possible target genes. However, p53, which is one of these key regulators, is found to be in low rank and keep itself at low profile but directly cross-talks with important genes BRCA2 and BRCA3. The popularity of these hubs gets changed in unpredictable way at various levels of organization thus showing disassortive nature. The local community paradigm approach in this network shows strong correlation of nodes in majority of modules/sub-modules (fast communication among nodes) and weak correlation of nodes only in few modules/sub-modules (slow communication among nodes) at various levels of network organization.

Zika virus (ZikV) has emerged as a potential threat to human health worldwide. A member of the Flaviviridae, ZikV is transmitted to humans by mosquitoes. It is related to other pathogenic vector-borne flaviviruses including dengue, West Nile and Japanese encephalitis viruses, but produces a comparatively mild disease in humans. As a result of its epidemic outbreak and the lack of potential medication, there is a need for improved vaccine/drugs. Computational techniques will provide further information about this virus. Comparative analysis of ZikV genomes should lead to the identification of the core characteristics that define a virus family, as well as its unique properties, while phylogenetic analysis will show the evolutionary relationships and provide clues about the protein's ancestry. Envelope glycoprotein of ZikV was obtained from a protein database and the most immunogenic epitope for T cells and B cells involved in cell-mediated immunity, whereas B cells are primarily responsible for humoral immunity. We mainly focused on MHC class I potential peptides. YRIMLSVHG, VLIFLSTAV and MMLELDPPF, GLDFSDLYY are the most potent peptides predicted as epitopes for CD4+ and CD8+ T cells, respectively, whereas MMLELDPPF and GLDFSDLYY had the highest pMHC-I immunogenicity score and these are further tested for interaction against the HLA molecules, using in silico docking techniques to verify the binding cleft epitope. However, this is an introductory approach to design an epitope-based peptide vaccine against ZikV; we hope that this model will be helpful in designing and predicting novel vaccine candidates.

Golden Mahseer ( Tor putitora) is an economically important fish of India and Southeast Asia. The present study examined the genetic variations between seven geographically isolated populations of T. putitora using Cyt b (Cytochrome b) and ATPase6/8 gene sequences of mitochondrial DNA. Analysis of 133 sequences of Cyt b (1141 bp) and 130 sequences of ATPase6/8 gene (842 bp) revealed 47 and 44 haplotypes, respectively. The estimated haplotype and nucleotide diversity was high in River Jia Bhoreli (Bhalukpong) population ( h = 1.00000, π = 0.007121 for Cyt b and h = 0.90441 π = 0.004867 for ATPase6/8). Results of AMOVA indicated that majority of the genetic variations in both genes were due to variation among populations (60.79% for Cyt b and 51.41% for ATPase6/8 gene). The pairwise F ST comparison and neighbor-joining tree revealed high genetic divergence of River Jia Bhoreli population from other populations. The understanding of genetic variations of T. putitora populations will play a key role in conservation and management of this endangered fish species. [ABSTRACT FROM AUTHOR]

Assamese kingfish (Cyprinion semiplotum) belonging to the subfamily Barbinae is an important food as well as aquarium fish having identified pharmacological benefits. The species has a complex taxonomic history and its phylogenetic position remains uncertain. Molecular data employed in earlier phylogenetic studies was inadequate for its phylogenetic placement. Therefore, we characterized 16,671 bp long complete mitogenome of C. semiplotum using next-generation sequencing. The mitogenome encodes the typical set of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and two non-coding regions. Its gene organization, distribution pattern, nucleotide composition, tRNA secondary structure and codon usage was similar to other Cyprinid mitogenomes. However, a distinctive 90 bp insertion was found in 3′ periphery of the AT-rich control region. This can be a tool for identification of the species at the population level. Further, we reconstructed the most comprehensive phylogenetic trees of Cyprinidae based on complete mitogenome. In the resulting phylogenetic trees, C. semiplotum clustered tightly with other Barbinae species and exhibited a sister relationship with the species of the genera Aulopye , Barbus , Luciobarbus and Capoeta. The results presented herein will support future investigations on molecular taxonomy, population genetics, evolution and molecular phylogeny of C. semiplotum and its relatives.

The stress driven dynamics of Notch-Wnt-p53 cross-talk is subjected to a few possible dynamical states governed by simple fractal rules, and allowed to decide its own fate by choosing one of these states which are contributed from long range correlation with varied fluctuations due to active molecular interaction. The topological properties of the networks corresponding to these dynamical states have hierarchical features with assortive structure. The stress signal driven by nutlin and modulated by mediator GSK3 acts as anti-apoptotic signal in this system, whereas, the stress signal driven by Axin and modulated by GSK3 behaves as anti-apoptotic for a certain range of Axin and GSK3 interaction, and beyond which the signal acts as favor-apoptotic signal. However, this stress system prefers to stay in an active dynamical state whose counterpart complex network is closest to hierarchical topology with exhibited roles of few interacting hubs. During the propagation of stress signal, the system allows the propagator pathway to inherit all possible properties of the state to the receiver pathway/pathways with slight modifications, indicating efficient information processing and democratic sharing of responsibilities in the system via cross-talk. The increase in the number of cross-talk pathways in the system favors to establish self-organization. [ABSTRACT FROM AUTHOR]

The present study will be helpful for the evolution and conservation genetic studies of N. hexagonolepis . [ABSTRACT FROM AUTHOR]

In fact, the risk of dying from CVD is significant when compared to the risk of developing end-stage renal disease (ESRD). Moreover, patients with severe CKD are often excluded from randomized controlled trials, making evidence-based therapy of comorbidities like CVD complicated. Thus, the goal of this study was to use an integrated bioinformatics approach to not only uncover Differentially Expressed Genes (DEGs), their associated functions, and pathways but also give a glimpse of how these two conditions are related at the molecular level. We started with GEO2R/R program (version 3.6.3, 64 bit) to get DEGs by comparing gene expression microarray data from CVD and CKD. Thereafter, the online STRING version 11.1 program was used to look for any correlations between all these common and/or overlapping DEGs, and the results were visualized using Cytoscape (version 3.8.0). Further, we used MCODE, a cytoscape plugin, and identified a total of 15 modules/clusters of the primary network. Interestingly, 10 of these modules contained our genes of interest (key genes). Out of these 10 modules that consist of 19 key genes (11 downregulated and 8 up-regulated), Module 1 (RPL13, RPLP0, RPS24, and RPS2) and module 5 (MYC, COX7B, and SOCS3) had the highest number of these genes. Then we used ClueGO to add a layer of GO terms with pathways to get a functionally ordered network. Finally, to identify the most influential nodes, we employed a novel technique called Integrated Value of Influence (IVI) by combining the network's most critical topological attributes. This method suggests that the nodes with many connections (calculated by hubness score) and high spreading potential (the spreader nodes are intended to have the most impact on the information flow in the network) are the most influential or essential nodes in a network. Thus, based on IVI values, hubness score, and spreading score, top 20 nodes were extracted, in which RPS27A non-seed gene and RPS2, a seed gene, came out to be the important node in the network., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Cardio-renal syndrome (CRS) is a rapidly recognized clinical entity which refers to the inextricably connection between heart and renal impairment, whereby abnormality to one organ directly promotes deterioration of the other one. Biological markers help to gain insight into the pathological processes for early diagnosis with higher accuracy of CRS using known clinical findings. Therefore, it is of interest to identify target genes in associated pathways implicated linked to CRS. Hence, 119 CRS genes were extracted from the literature to construct the PPIN network. We used the MCODE tool to generate modules from network so as to select the top 10 modules from 23 available modules. The modules were further analyzed to identify 12 essential genes in the network. These biomarkers are potential emerging tools for understanding the pathophysiologic mechanisms for the early diagnosis of CRS. Ontological analysis shows that they are rich in MF protease binding and endo-peptidase inhibitor activity. Thus, this data help increase our knowledge on CRS to improve clinical management of the disease., (© 2021 Biomedical Informatics.)

The Snowtrout, Schizothorax richardsonii , is a vulnerable fish species found in different rivers and rivulets of the Himalayan region. The species is also a suitable poikilotherm to study the low-temperature tolerance as it dwells well at a temperature range of 5-20 °C. The solute carrier (SLC) group of membrane transport proteins play an integral role in cellular acclimation response. The present RNA sequencing was done to identify solute carrier transporter which are the major gene cascades responsible for transport of sugars, amino acids, oligonucleotides, ions, drugs, etc. to and from the cell organelles. A reference transcriptome database was created from liver tissue of Schizothorax richardsonii through RNA sequencing on Illumina HiSeq 2000 platform. The sequences were annotated and characterized under various solute carrier families in the species. So far, 113 transcripts were identified as solute carrier transporter genes categorized under 13 different families. This data will be useful for many researchers working on gene cloning and differential expression of solute carriers.

This study examined the phylogenetic relationship and identification of five Mahseer species (Tor putitoro, Tor tor, Tor khudree, Tor chelynoides and Neolissochilus hexogonolopis) using partial sequencing of a Cytochrome Oxidase I (COl) DNA barcodes. The sequence analysis data showed that 134 (21.61%) sites out of 628 sites were variable without insertion or deletion. Rate of transition (70.5%) were higher than transversion (29.41%). There was a high inter-species divergence (range 4.1% to 12.2%) in Mahseer species as compared to intra-specific sequence divergence (1.7% for T. putitora, 1.2% for T tor, 1.4% for T. khudree, 3.0% for T chelynoides, 0.26 % for N. hexagonolopis). The phylogenetic tree, constructed by maximum parsimony, maximum likelihood and unweighted pair group average methods revealed similar results suggesting that T. putitoro, T. tor and T. khudree had a close relationship to each other while maximum divergence was observed in T. chelynoides, which was also confirmed by the genetic distance data. The results indicate that COl sequencing or bar-coding is useful in unravelling phylogenetic relationship and identification of Mahseer species.

The propagation of Ca2+ wave through gap junction in smooth muscle cell is studied as a function of electrical coupling parameter (g) modulated by Ca2+ level in the cell. The range of activation time of Ca2+ propagation with amplitude is found to increase as increase in electrical coupling parameter g, which is identified by increase in critical time of activation, T(F) as a function of g. Then identical Ca2+ oscillators are allowed to interact via electrical and diffusive coupling of Ca2+ ions diffused through gap junctions, and rate of intercellular synchronization among them is studied. The phase diagrams in (T(F) - g) and (T(F) - epsilon) parameter spaces separate oscillation death and damped oscillations regimes which correspond to deactivated and activated regimes of Ca2+ level. The effect of on T(F) is significantly very slow, however it enhances the rate of synchronization among the coupled oscillators. The increase in g comparatively slows down the rate of synchronization of the coupled oscillators as shown in the phase diagram in (epsilon - g) parameter space which separates desynchronized and synchronized regimes.

There is paucity of literature regarding the anaesthetic management of patients with thalassaemia intermedia. In this case study, the anaesthetic management and concerns in two children with thalassaemia intermedia aged eleven and nine years undergoing herniotomy and splenectomy respectively is reported. Both children had unanticipated difficulty in airway management and high intraoperative blood pressure trends. These cases are representative of the range of problems seen in children with thalassaemia intermedia.
