A very tiny non-coding RNA molecule with a length of 20 to 24 nucleotides, called microRNAs or miRNAs. They control gene expression by targeting mRNAs with sequence-specificity. Depending on the degree of complementarity with the target mRNA sequences, this might result in translational repression or mRNA destruction. They are very crucial for controlling growth and development in plants. Researchers also agreed with the point that miRNAs are responsive to stress in plants. Growing in tropical and subtropical estuaries, mangrove is a very significant ecosystem both environmentally and commercially. But several natural processes, like sea level rise, salinity rise, and global warming, are disastrous for this flora, and some species are disappearing at a startling rate. Studying the function of these miRNAs in controlling mangrove homeostasis in that situation would be of utmost significance. In the most recent research, we discovered three miRNAs: ph-miR10630, ph-miR11471, and ph-miR10341 in Phoenix sp, that react to abiotic stress. This finding unmistakably indicates that miRNAs play a regulatory function in preserving cellular homeostasis. When...

Background: Evidence based medicine (EBM) integrates the best available data from clinical research into clinical practice. Residents (PGs & CRRIs) are at the frontiers of healthcare who are still struggling to adapt the paradigm shift in the practice of medicine. This study aims to explore the knowledge and attitude of EBM among residents in a tertiary teaching hospital. Materials and Methods: After IEC approval, this cross-sectional questionnaire study was conducted among PGs and CRRIs in Melmaruvathur Adhiparasakthi institute of medical sciences & Research for 3 months. All the 81 CRRIs and 51 PGs were enrolled. Written informed consent was obtained. The pre-validated, 20 questionnaires, designed based on McColl questionnaire has been used to obtain information about the knowledge (10 questions) and attitude (10 questions) of EBM. SPSS 21.0 was used for data analysis Results: Out of 132 participants, 63.81% had formal EBM training while, 21.21 % had no previous exposure. Regarding the knowledge of some commonly used technical terms in EBM, 84.31% (43) of PGs and 11.11% (9) of...

Introduction: Preeclampsia (PE) is a common pregnancy-related hypertensive disorder that may result from abnormal placental development and is a major threat to the mother’s and foetus’s life. Methods: Placental miRNAs (miRNAs) profile was investigated using next-generation sequencing for the identification of potential biomarkers playing a role in aberrant placental development and to understand the pathophysiology(space between ‘the’ and ‘pathophysiology’) of PE. Placental tissues were collected from three patient groups (Control [n = 30], Early Onset of Preeclampsia (EOPE) [n = 30], and Late Onset of Preeclampsia (LOPE) [n = 30]) and performed miRNA profilingby Illumina sequencing, downstream analysis for identification, quantification and expression profiling is done by the quantifier.pl, script, and miRDeep2.pl, script. Results: Sequence analysis showed novel miRNAs that were disease-specific and common among all studied groups, suggesting the underlying placental pathologies in EOPE and LOPE. The real-time PCR analysis of 3 miRNAs (miR4743-5p, miR149-5p, and miR331-5p) was done, and observed differential expression in all three patient groups. MiRNA4743-5p was found to be significantly expressed EOPE when compared to control...

One of the most important difficulties in contemporary medical biology is the creation of a cutting-edge, effective drug delivery system with a considerable improvement in its efficacy and increased therapeutic value. The advancement and development of innovative drug-delivery nanocarrier systems with accuracy and reduced side effects have been made possible by merging nanomaterial science with molecular and cellular biology. Over the past few years, the design and manufacture of nanocarriers using graphene oxide (GO) have grown quickly. Because of its amazing physicochemical features, GO has been widely exploited in efforts to create nanocarriers with high specificity, selectivity, biocompatibility, and minimal cytotoxicity. This review focuses on recent applications, synthesis, of GO-based nanocarriers, and advancements in enceinte drug delivery systems. Following a brief explanation of the principles and difficulties surrounding nanocarrier systems, we offer important illustrations of the transport of drugs and genes using GO. The assessment concludes with a few succinct observations on what is known currently and what the future may hold for nanocarrier delivery...

Clitoria ternatea was selected because it possesses various medicinal compounds of great significance based on its usage as an ayurvedic drug to cure various diseases. This study helps to understand the significance of plant sources that possess pharmacological activities and is good for health on regular consumption. A comparative study was thus conducted to analyze the potential antioxidant activity by experimental quantifying the certain bioactive compounds present in the aqueous and methanolic extracts of the fresh and dry flowers of the blue flowered variety of Clitoria ternatea. This study showed that all the extracts possessed desirable antioxidant activity examined by DPPH assay and peroxide value assessment due to considerable amounts of secondary metabolites like flavonoids, phenols, steroids etc., determined quantitatively during the phytochemical analysis. Although the dry methanolic extract showed positive results overall during the phytochemical analysis, the fresh aqueous extract of C. ternatea showed the highest antioxidant property with 63.63% scavenging...
