Molecular Methods to Improve the Insecticidal Action of Bacillus thuringiensis in Biotechnology Arena
type: item
description: Abstract Bacillus thuringiensis (or Bt) is a Gram-positive, soil-dwelling bacterium, frequently used as an organic pesticide. B. thuringiensis also arises naturally in the gut of caterpillars of several kinds of moths and butterflies, as well on foliage surfaces, marine environments, animal feces, insect-rich surroundings, and flour mills and grain-storage facilities. All through sporulation, various Bt strains harvest crystal proteins (proteinaceous inclusions), termed δ-endotoxins, that have insecticidal action. This has led to their use as pesticides, and more recently to genetically improved crops using Bt genes, such as Bt corn. Numerous crystal-producing Bt strains, however, do not have insecticidal properties. We define natural and in vitro growth of Cry toxins, as well as their significance in the mechanism of action for insect control. Furthermore, the use of DNA shuffling to develop two Bt toxins will be conversed together with in silico analyses of the generated mutations to evaluate their possible effect on protein structure and cytotoxicity.

Comparative Study on Bioremediation for Oil Spills Using Microbes
type: item
description: Abstract This research work was designed to compare and evaluate the capacity of microbes in bioremediating and biodegrading of hydrocarbons which are the major constituents of petroleum oil. An oil spill is a leakage from ocean-going tankers, pipelines or other oil sources. Bioremediation for oil spills is a technique that uses microbes to eliminate contamination of hydrocarbons from water and soil, thereby making them safe for aquatic and terrestrial species. Bioremediation can be used by bacterial species, fungal species (by a process called mycoremediation) and plant species (by a process called phytoremediation). Two different species—bacterial species (Pseudomonas putida) and fungal species (Penicillium chrysogenum)—were checked individually in the laboratory condition, in order to determine and test for their capabilities in bioremediation process in oil spills. The total aerobic bacterial and fungal counts and cfu result were carried out after first and second weeks of inoculation, and was found to be significant. Solvent extraction method was primarily used to determine the percentage of oil degraded. P. chrysogenum degraded 11.1% of the oil in two weeks and P. putida degraded 6.425% after two weeks; this shows P. chrysogenum was found to degrade oil better than P. putida. Gas chromatographic (GC-MS) analysis of the residual oil extracted from bacterial, fungal as well as the control set up showed marked variations in peaks representing individual hydrocarbon components being degraded and transformed. Higher degradation was obtained with P. chrysogenum having lower peaks as compared to the bacterial and the control set up. This further confirmed the result obtained earlier with the solvent extraction method. There are three methods to clean up oil spills— physical, chemical and biological (bioremediation); but bioremediation is advantageous as it is time and cost saving than physical metho. Also unlike chemical method, no foreign or toxic chemicals are adde…

The HbA1C Values Used in Diagnosis of Diabetes in India—A Review
type: item
description: Abstract Diabetes mellitus (DM) is a chronic metabolic disorder associated with retinopathy, nephropathy, cardiovascular disorder and other lethal complication of organ system. It has huge burden globally and expected to grow more in upcoming years; with alarming presence in epidemic proportions in countries like India and China. India currently faces challenges to handle the potential burden of DM which demands accurate and precise diagnosis by various clinical parameters. Since 2009, HbA1c was recommended as diagnosis of DM and management of related complications. Still in India, fasting plasma glucose (FPG), post-meal glucose and oral glucose tolerance test (OGTT) are commonly used, due to unregulated diagnostic sector and lack of awareness. However, combination of FPG, OGTT and HbA1c are reported by laboratories having adequate facilities. In depth studies on impact of laboratory quality and education of physicians, healthcare providers, pathologist may improve harmonisation and quality of patient care in DM in India.

Correlation Between eAG Values Calculated from Hba1c Values Obtained from Three Different Techniques and Fasting Plasma Glucose Levels for Diagnosis and Prognosis of Diabetes
type: item
description: Abstract The objective of the present study was to correlate estimated average glucose (eAG) values calculated from HbA1c values obtained from Tosoh TLC-723 G8 based on cation exchange based HPLC, TBA 12 FR enzymatic fructosyl peptide oxidase (FPOX) method and D10 HbA1c analyser Bio Rad Laboratories (USA) with fasting plasma glucose (FPG) levels by hexakinase method for diagnosis and prognosis of diabetes. A total of 300 randomly selected patient samples were analysed for FPG by hexakinase method and HbA1c values were estimated by using Tosoh TLC-723 G8 analyser based on cation exchange HPLC, enzymatic FPOX (Manufacture by Seikisui Medical Co. Ltd., Japan) programmed on TBA 12 FR biochemistry analyser and D10 HbA1c analyser Bio Rad Laboratories (USA). The eAG values were calculated using Nanthan’s regression equation for both HbA1c values. The correlation between FPG, HbA1c and eAG values has been done by Pearson correlation (r) and regression analysis was done by SPSS software. The correlation was good in entire data and poor in differentiated groups. Male data has shown good correlation between FPG and eAG as compared to female data with higher mean levels of FPG, eAG and HbA1c values. Both HPLC methods have shown closer correlation between eAG values calculated from it and FPG values from which Tosoh HLC-723 G8 has shown closer correlation. The overall correlation between eAG and FPG was good in entire data but mean value difference was found to be slightly high. So for diabetes diagnosis, HbA1c values along with calculated eAG value along with FPG values are recommended as per the American Diabetes Association (ADA) guidelines. As both the HPLC methods have shown good correlation between eAG and FPG values, we recommend that HbA1c values and eAG values calculated from it has to be used for diagnosis and prognosis of diabetes along with FPG values and other relevant clinical findings of patients. Tosoh HLC-723 G8 HPLC HbA1c analyser could be preferred technique f…

Isolation and Characterization of Lantibiotic Producing Lactic Acid Bacteria from Ambali, Aged Mango Pickle Probiotics
type: item
description: Abstract Each year in the US at least 2 million people are sickened with antibiotic resistant infection. The development of antibiotics was one of the most important advances of medicine. Many bacterial infections (e.g. tuberculosis and infected wounds) that previously had no effective treatment and often killed people became treatable with antibiotics, saving millions of lives. Now, because of the overuse and misuse of antibiotics, bacterial infections that were once easily cured with antibiotics are becoming harder to treat. This is due to antibiotic resistance. The World Health Organization has called this as one of the biggest threats to human health today (World Health Organization 2014). Antibiotics have transformed human health and saved millions of lives. Now, as a result of overuse, they are no longer working. The golden age of medicine has come to an end (Joe Shute). But 99% of microbes will not grow in laboratory conditions leaving researchers frustrated that they could not get to the life-saving natural drugs. The dramatic rise in the incidence of antibiotic resistance demands that new therapeutic options will have to be developed. One potentially interesting class of antimicrobials is the modified bacteriocins termed lantibiotics, which are bacterially produced, post-translationally modified, lanthionine/methyllanthionine containing peptides. The present study was aimed at isolating bacteriocinogenic LAB from a traditional fermented food, “Ambali”. Twenty five colonies of LAB were isolated and screened for bacteriocin production potential. Ten isolates showed good antimicrobial activity against Gram-positive viz., Bacillus cereus, Staphylococcus aureus, Listeria monocytogenes as well as Gram-negative viz., Pseudomonas aeruginosa, Vibrio parahaemolyticus and Aeromonas hydrophila microorganisms. During characterization of these strains, two of them were found to resemble two other strains. One of the bacilli has been reported earlier. Therefore, in this s…

Hereditary Disease and Ethical Awareness in Students of Greater Noida, India
type: item
description: Abstract Hereditary diseases are diseases that are transmitted from parents to offsprings. These diseases cause many deaths and sufferings in the world. Often majority of people in developing countries suffer because of illiteracy and ignorance, and are not able to take right decision when the problem persists in the family. Therefore, a survey has been designed and conducted on students of engineering and management branches between age group 18 and 25 years to check general awareness regarding hereditary diseases. In the survey, fifteen questions were asked. The result shows general awareness to be present among most of the students about ethics and inherited diseases. Most of the students think that parents should go for pre-genetic counseling before giving birth to their forthcoming child if the disease is hereditary one. Majority believes that parents should maintain confidentiality from children and society about hereditary disease because of mass discrimination for one or other reasons. However, the suspected individual with a family history of hereditary disease should opt for DNA testing so that diseases can be prevented, treated or cured in advance. In case of incurable inheritable disease, students feel that the knowledge may mislead and cause stress, pain, depression and anxiety. The present article highlights the different views and perspectives of students on different aspects of inherited diseases and ethical awareness related to it.

A Review: Quantitative Structure Activity Relationship
type: item
description: Abstract Drug discovery is a risky, costly and time-consuming process depending on multidisciplinary methods to create safe and effective medicines. Although considerable progress has been made by high-throughput screening methods in drug design, the cost of developing contemporary approved drugs did not match that in the past decade. The major reason is the late-stage clinical failures in Phases II and III because of the complicated interactions between drug-specific, human body and environmental aspects affecting the safety and efficacy of a drug. There is a growing hope that systems-level consideration may provide a new perspective to overcome such current difficulties of drug discovery and development. Therefore, the present review is an attempt to introduce how holistic systems pharmacology that integrated in silico ADME/T (i.e., absorption, distribution, metabolism, excretion and toxicity), target fishing and network pharmacology facilitates the discovery of small molecular drugs at the system level.

Molecular Dynamics Simulation of RND Efflux Pumps Involved in Multidrug Resistance
type: item
description: Abstract The appearance of resistant strains of Gram-negative bacteria against antibiotics has compromised the efficiency of treatment. Multidrug resistance (MDR) is mainly due to the involvement of Resistance-nodulation division (RND) efflux pumps that actively pump out the drugs. For inhibition of the pump, it is essential to understand the structure as well as molecular basis of the process. Molecular dynamics (MD)simulationis employed to understand the conformational dynamics and functional mechanism of the pumps.

An Overview on Bioinformatics and its Application
type: item
description: Abstract Bioinformatics has become an important part of many areas of biology.The term ‘Bioinformatics’ was coined by PaulienHogeweg in 1979. In experimental molecular biology, bioinformatics techniques such as image and signal processing allow extraction of useful results from large amounts of raw data. In the field of genetics and genomics, it aids in sequencing and annotating genomes and their observedmutations. It plays a role in the text mining of biological literature and the development of biological and gene ontologies to organize and query biological data. It also plays a role in the analysis of gene and protein expression and regulation. Bioinformatics tools aid in the comparison of genetic and genomic data and more generally in the understanding of evolutionary aspects of molecular biology. At a more integrative level, it helps to analyze and catalogue the biological pathways and networks that are an important part of systems biology. In structural biology, it aids in the simulation and modeling of DNA, RNA, proteins as well as biomolecular interactions.

Molecular Docking: A Powerful Approach for Structure based Drug Discovery
type: item
description: Abstract Molecular Docking is a method which predicts the preferred orientation of one molecule to a second when bound to each other to form a stable complex. Knowledge of the preferred orientation in turn may be used to predict the strength of association or binding affinity between two molecules using, for example, scoring functions. The associations between biologically relevant molecules such as proteins, nucleic acids, carbohydrates, and lipids play a central role in signal transduction. Furthermore, the relative orientation of the two interacting partners may affect the type of signal produced (e.g., agonism versus antagonism). Therefore, docking is useful for predicting both the strength and type of signal produced. Molecular docking is one of the most frequently used methods in structure-based drug design, due to its ability to predict the binding-conformation of small molecule ligands to the appropriate target binding site. Characterisation of the binding behaviour plays an important role in rational design of drugs as well as to elucidate fundamental biochemical processes.

Phylogenomic Analysis of Human Multigene Families Using Computational Approach
type: item
description: Abstract Evolution leads to major morphological transformations and anatomical complexity achieved by higher vertebrates. The phylogenomic analysis of human multigene families (ERBB, HCK, VAMP) was conducted to check the evolutionary history and functional significance. The colossal amount of diversified protein dataset for a wide variety of vertebrates and invertebrates was used to derive the phylogeny of highly significant and functionally diverse gene families. Phylogenetic analysis reveals the mode of evolution and conservation of three gene families residing on human chromosomes. Phylogeny advocates that the expansion of multigene families has occurred after diversification of vertebrates from urochordates and prior to fish–tetrapod split. The gene duplication events occurred after speciation of vertebrates and invertebrates. The major duplications occurred within the time window of deuterostomes–protostomes and actinopterygii–sarcopterygii split. The phylogenetic analysis of multigene families exhibits high level of conservation and evolutionary significance. Phylogenetic tree reflects chromosomal segmental duplications or small-scale duplications which occurred at different time points during chordate evolution. Lineage-specific deletion events were also detected in fish and tetrapods. The study will provide better understanding of ancestral relationship and functional behavior of human multigene families to the scientists belonging to diversified fields of biology, especially comparative and evolutionary genomics biologists.

DNA Barcoding
type: item
description: Abstract DNA barcoding system is a promising approach towards the diagnosis of biological diversity using DNA sequences as a primary key for retrieval of genetic information. It is emerging as a standardised method for mapping various species on the earth. DNA barcoding is a tool for identification of new species, conservation of endangered species and clustering of various species under a particular group. Many databases have been developed across the globe for the quick assessment of various DNA barcodes. Consortium for the Barcode of Life (CBOL) and Barcode of Life Database (BOLD) serves as the major barcode sources for the researchers in species identification. There are few accepted barcodes across the globe for identification of the species such as CO1 gene for animals and rbcL, matK, trnH-psbA for plants and ITS gene for fungal species. Hence DNA barcoding is the new modernised, speedy, precise and consistent method for biodiversity identification. This review study shows salient features of DNA barcoding system as a simple modernised taxonomical tool for species identifications.

rbcL Gene Based Molecular Phylogenetic Studies of Certain Pteridophytes of Assam
type: item
description: Abstract About 16 species of pteridophytes found in Assam (India), were selected and their variation in chloroplast rbcL gene sequences were studied. Molecular phylogenetic analysis was performed using rbcL gene sequences where a bryophyte, Funaria hygrometrica was taken as outgroup sequence. The result showed that the outgroup Funaria hygrometrica forms a totally separate branching from rest of the pteridophytic species.

Analysis of Transcription Factor Binding Sites of Co-expressed Genes in Colorectal Tumor by Microarray Data Analysis
type: item
description: The utilization of global gene expression profiling to find genes with similar expression patterns is rapidly becoming an extensive approach for understanding the complex cellular processes and disease mechanism. The polygenic nature of colorectal tumor, one of the most deadly cancers worldwide is believed to be caused not only by defects in single gene, but rather by the variation in multiple genes and their complex interactions. However, the regulatory mechanisms driving these changes, particularly the network of transcription factors, were not understood completely. Screening of differentially expressed genes (DEGs) through microarray data analysis and further functional enrichment analysis of these DEGs showed the importance of matrix metalloproteinase (MMPs) in the treatment of colorectal tumor. The detection of conserved TFBS in the promoter regions of DEGs showed the involvement of TFBS classes, FOXO3 and ARID3A to be involved in the development of tumor.

Methodologies for in silico and in vitro Test of Biphenylalanine Compounds as Potential HIV-1 gp120 Attachment Inhibitors
type: item
description: We postulate that biphenylalanine and its derivatives are propitious candidates to inhibit the binding of HIV-gp120 to CD4 T-cell. Many biphenylalanine derivatives are synthesized chemically and also prevailing in nature. We have proposed atom- and bond-based 2D TOMOCOMD-CARDD approach to identify the best derivative. Moreover, according to our proposition, the principal law simulated from in silico interaction of gp120 with CD4 can be tested by ELISA in vitro. Furthermore, the toxicity of biphenylalanine compounds might be evaluated using MTT cytotoxicity test kits for future development of attachment inhibitors in vivo. It will be a novel idea to determine the efficacy of biphenylalanine compounds as a drug. To determine, in advance the possible stable mutation forms (all mutations are not stable) around the apolar ‘Phe43 cavity’ on gp120 and predict the next generation drugs against these mutations we opine to develop a discriminated function of local (amino acid-type) linear indices of the “macromolecular pseudograph’s α-carbon atom adjacency matrix”- that permits the classification of mutants as near wild type stability or reduced stability. To sum up, the consummate biphenylalanine substances will likely to be an ace in a hole for millions of people worldwide.

Molecular Interaction and Simulation Studies of Inhibitors for Endothelin-1 Receptors
type: item
description: High altitude cerebral edema (HACE) is a life threatening severe form of acute mountain sickness (AMS) which causes headache, unbalanced gait, behavioral changes, and altered mental status. It also carries features like hallucinations or coma, as well as a variety of neurological deficits. Prevention of edema fluid formation with minimal side effects remains to be discovered. Endothelin-1 receptors were found to be involved in the pathogenesis of HACE. Due to the elevated level of Endothelin-1(ET-1), cerebral edema levels increase. In the present study, the authors have identified possible interactions of seven spirodihydro benzofuranlactam derivatives with the two endothelin-1 receptors A and B.

Evaluation of Penalized Estimation Methods for Big Data Analysis
type: item
description: In this paper we described the sparse Laplacian shrinkage (SLS) method which is a penalized method for variable selection and estimation in big data analysis that uses a combination of the minimax concave penalty (MCP) and Laplacian quadratic as the penalty. The SLS uses the MCP to promote sparsity and Laplacian quadratic penalty to encourage smoothness among coefficients associated with the correlated predictors. An important advantage of the MCP over the penalty is that it leads to estimators that are nearly unbiased and achieve selection consistency under weaker conditions. In some problems such as genomic data analysis, partial external information may also be available on the graphical structure of some genes used as predictors in the model. It would be interesting to consider approaches for combining external information on the graphical structure with existing data in constructing the Laplacian quadratic penalty. We discussed a comparative study with ridge regression (Ridge), Lasso, MCP and SLS estimator. For different sample and variable size, our simulation studies demonstrate that SLS estimator is the best estimator.
