    Abstract The term atherosclerosis refers to the condition of deposition of lipids and other substances in and on the artery walls, called as plaque that restricts the normal blood flow. The plaque may be stable or unstable in nature. Unstable plaque can burst and trigger clot formation adding further adversities. The process of plaque formation involves various stages including fatty streak, intermediate or fibro-fatty lesion and advanced lesion. The cells participating in the formation of atherosclerotic plaque include endothelial cells, vascular smooth muscle cells (VSMC), monocytes, monocytes derived macrophages, macrophages and dendritic cells and regulatory T cells (T

    Abstract During the 19th century, for the first time, the linkage between inflammation and cancer was established. Inflammatory microenvironment is an essential component of the tumor microenvironment. Chronic inflammation due to persistent infection due to the microbes, viruses, helminths or constant exposure to non-infectious factors like smoke, silica or asbestos eventually might result in carcinogenesis. In tumor microenvironment, various inflammatory cells such as T lymphocytes (occasionally B cells), dendritic cells, macrophages, monocytes, neutrophils and natural killer (NK) cells are present. As a mediator of immune surveillance and host defense TRAIL cytokines are produced which upon binding with death receptors (DRs) initiate a cascade of apoptotic pathways. Anti-inflammatory drugs such as aspirin, celecoxib, diclofenac, diflunisal and ibuprofen etc. are being used against cancer, indicating the interplay between both the mechanisms. A deeper understanding of common pathways implicated between both the inflammation and cancer may pave the way to fight against both of these deleterious ailments.

    Abstract Mycobacterium lepromatosis was identified as a causative agent for leprosy in the year 2008 in the United States and later more cases were identified in Canada, Singapore, Brazil, and Myanmar. It is known to cause diffuse lepromatosis leprosy among humans. Since it is invasive, the mortality rates are higher in comparison to the M. leprae. At genomic level, there exists 90.9% similarity between M. lepromatosis and M. leprae. Codon usage analysis based on analyses of 228 coding sequences (CDSs) of M. lepromatosis, revealed that the genome is GC rich. Among the total 16 dinucleotides, CpG dinucleotide possesses the highest dinucleotide frequency in M. lepromatosis, that is strikingly an unobvious observation since higher CpG is associated with higher proinflammatory cytokine production and NF-κB activation that eventually leads to high pathogenicity. To evade immune response, CpG content is generally less in pathogens. The unusually high CpG content can be explained by the fact that the nucleotide composition of M. lepromatosis is CG rich. Various forces interplay to shape codon usage pattern of any organism including selection; mutation, nucleotide composition as well as GC biased gene conversion. To understand the interplay between various forces; neutrality, parity, Nc-GC3 (Effective number of codons-GC content at 3rd position of the codon), aromaticity (AROMO) and the general average hydropathicity score (GRAVY) analyses have been carried out. The analyses revealed that selection force is the major contributory force. Along with the selection; mutation, nucleotide composition as well as GC biased gene conversion also play role in shaping codon usage bias in M. lepromatosis. This is the first report on the codon usage in M. lepromatosis.

    Abstract Sanger's dideoxy chain termination method was the widely used technology for DNA sequencing since its inception. However, the technique has its own limitations like it is costly, time consuming, labor intensive and faces the problem of clone biasness. Pyrosequencing has emerged as a novel sequencing technique, which offers potential advantages in terms of accuracy, cost effectiveness, flexibility, parallel processing, high throughput and further it can be easily automated. It can be widely accepted for the detailed characterization of nucleic acids. The technique is advantageous in DNA sequencing, genotyping, single nucleotide polymorphism analysis, allelic discrimination, allelic quantification and whole-genome sequencing. The technique may be broadly used in area of biotechnology, clinical genetics and pharmacogenetics. Due to efficacy and reliability, the technique may be used in the high-throughput analysis of bacterial and viral samples as well as metagenomic studies. Currently, the technique is the basis of next generation sequencing platform, offered by 454 Life Sciences as an array-based pyrosequencing technology.

    Abstract Insecticides are widely used in agriculture to curb the loss caused by insects. These insecticides are incorporated into the food chain and accumulate in the human body, as well disturb the various metabolic pathways. Imidacloprid is an insect neurotoxin commonly used in agriculture to control the insect pests. P. niruri is a traditional medicinal shrub widely used as an anti-inflammatory, antipyretic, and anti-lethality agent.The present study is designed to evaluate the ameliorative effects of Phyllanthus niruri (Bhumi amla) on the deleterious Insecticide imidacloprid in the vital organs of Chicken embryos.The embryonated chicken eggs were divided into the four groups (one control and three treated groups); the chorioallantoic membranes of control received 200 μl phosphate buffer saline, whereas group I and group II received 100 μg imidacloprid and 200 μl aqueous extract of P. niruri (PNE) respectively. Group III received both 100 μg imidacloprid and 200 μl PNE. The serum was collected on the 18th day its development; which was subjected to the biochemical analysis based on colorimetric assay in semi-automated biochemical analyzer using commercial kits.We observed significant in ovo effects of imidacloprid on chicken embryos; the values of aspartate aminotransferase (AST), alanine aminotransferase (ALT), were increased in imidacloprid treated group I; histopathology also revealed damage to the liver (necrotic areas and dilated blood sinusoids). Alkaline phosphatase (ALP), amylase, cholesterol, triglycerides protein and albumin levels were also altered significantly (p < 0.05).The serum biochemicals were returned back to the nearly normal levels. PNE has ameliorated and overcome the effects of imidacloprid reasonably with the subsequent treatment among group III. Hence, P. niruri may be used to minimize the effects of an accidental exposure of imidacloprid.

    Abstract Background: Heat shock proteins (HSPs) are highly conserved proteins present in all kingdoms of organisms. These are expressed under stress conditions in order to protect the cells from injuries. The stress induced protein denaturation is rectified by refolding and remodelling. These are intracellular proteins but can be present in extracellular fluid like serum of the patients suffering from trauma, autoimmune and inflammatory disorders. Virtually in most inflammatory diseases, immune response towards HSPs is developed.
    Objective: The present review expedites the role of HSPs in inflammatory process and associated disorders, mainly in context to HSP70 and HSP90.
    Method: Commencing a thorough survey of the literature and patents available on HSPs and their role in the process of inflammation, from the authentic published resources available on Medline, Pubmed, Pubmed Central, Science Direct and other scientific databases; the information retrieved has been compiled and analyzed.
    Results: HSPs modulate the process of inflammation by producing anti-inflammatory cytokines in chronic inflammatory disease. HSPs mediated expression of IL10 contributes in anti-inflammatory role via TLR2 and TLR4-dependent mechanisms. Necroptosis, a caspase independent programmed apoptosis plays an important role in progression of several inflammatory disorders and its major components MLKL and RIPK-1 are the clients of HSP. Necroptosis is also involved in exposure of several damageassociated molecular patterns (DAMPs) including HSPs in extracellular environment leading to inflammation. Endocytosed or intracellular HSP70, is presented by MHC-II molecules and in absence of proper co stimulation, it lead to expansion of tolerogenic or regulatory T cells (Tregs) responses, which have inflammation suppressive activity by virtue of production of anti-inflammatory cytokines, suppression or killing of effector T cells or bringing the APC into tolerogenic state. HSP induced Tregs play an important role in combating autoimmunity and inflammation.
    Conclusion: Present review gives an insight towards the cause of inflammation and an account of different HSPs contributing various inflammatory disorders viz. inflammatory bowel disease (IBD), intestinal inflammation, atherosclerosis, rheumatoid arthritis (RA), multiple sclerosis etc. The importance of HSPs in handling inflammatory disorders has been depicted in recent patents also.
