    Abstract: Pancreatic cancer is a major problem worldwide and the fourth leading cause of cancer-related deaths in the United States. In the pancreatic malignancy, long term smoking is the most established risk factor. Cigarette smoke contains a variety of constituents of which nicotine is the major component present. Previously, we have shown that MUC4, a member of transmembrane mucin family, is aberrantly expressed in the pancreatic tumors compared to the normal pancreas and is functionally involved in the tumorigenecity and metastasis of pancreatic cancer. The aim of the study was to investigate the role of nicotine on the pathogenesis of pancreatic cancer and to check if MUC4 is the major regulator involved in the process. The western blot and confocal analysis showed a gradual increase in the expression of MUC4 with nicotine treatment of the cells in a dose-dependent manner. Further, it was seen that retinoic acid (RA), a known MUC4 regulator, plays a synergistic role along with the nicotine, in up-regulating MUC4 expression in CD18/HPAF-SF. Further, studies were performed in order to elucidate the possible regulatory mechanism behind the nicotine mediated MUC4 induction and it's downstream signaling. RT PCR and western blot analysis showed an over expression of the nicotine receptor subunit α7 in nicotine-treated CD-18/HPAF as compared to the untreated cells. In addition, the study revealed that the α7 nicotine receptor subunit mediated JAK2-STAT3 pathway and the FAK activation, are the main regulatory mechanisms involved. Furthermore, the role of the α7 nicotine receptor subunit was confirmed by treating the cells with an α7 receptor antagonist, DhβE, which reduced the MUC4 expression and the JAK2 mediated activation of STAT3. In addition, in vitro functional assays were performed to assess the effect of nicotine induced MUC4 on CD-18/HPAF cells. Interestingly, the wound healing assay showed an increase in the migration potential of nicotine treated CD-18/HPAF cells as compared to the untreated cells. The western blot analysis provides clear evidence that nicotine also facilitate the phenomenon of EMT in CD-18/HPAF cells as shown by the down-regulation of the epithleial marker, E-cadherin, and an up-regulation of the mesenchymal marker, N-cadherin. Overall, our study shows a malignant potential of nicotine in the pancreatic cancer pathogenesis through α7 receptor subunit mediated MUC4 induction, thereby, increasing the migration potential of pancreatic cancer cells.

    Abstract: Pectinases are a collection of multiple enzymes that have a common substrate, that is, pectin. They can act on different parts of pectin due to the structural heterogeneity of pectin. Therefore, they have been placed in different groups, such as protopectinases, polygalacturonases, polymethylesterases, pectin lyases, and pectate lyases. They are naturally present both in multicellular organisms such as higher plants and in unicellular organisms such as microbes. In past decade, it has been witnessed that chemical and mechanical methods employed in industrial processes have led to environmental hazards and serious health disorders, thus increasing the search for eco‐friendly approaches with minimal health risks. Hence, microbial enzymes have been extensively used as safer alternative for these environmentally unsafe methods. Among these microbial enzymes, pectinases hold great significance and is one of the principal enzymes that have been used commercially. It is predominantly used as a green biocatalyst for fruit, fiber, oil, textile, beverage, pulp, and paper industry. Thus, this review focuses on the structure of pectin, microbial sources of pectin, and principle industrial applications of pectinases.

    Abstract: A study of organic, integrated and inorganic plant nutrient management systems was conducted to determine the effect of management practices on soil microbiological properties after 10 years of continuous application. The rate of C mineralization and potentially mineralizable nitrogen were 6.8 and 41.5 mg/kg soil, respectively. Arginine ammonification and nitrification activities were 0.88 µg NH4+- N/g soil/h and 56.0 µg NO3--N/g/day, respectively. Microbial biomass C, N and P were 320, 40 and 12 mg/kg soil, respectively. Alkaline phosphatase, urease and cellulase activities were highest with application of VC@15t /ha.

    Abstract: The genus Hibiscus belongs to the mallow family, Malvaceae comprising of about 275 species growing in tropical and sub tropical areas. The various species of genus Hibiscus have been used as traditional medicine all over the world. There are numerous reports of their traditional medicinal uses in various countries like India, Nigeria, China, and Srilanka etc. to cure various ailments such as hypertension, cardiac diseases, stomach-ache, urine problems, skin diseases and many more. Based on the historical knowledge, various pharmacological and phytochemical studies on some species of the genus Hibiscus have been done. Nevertheless, there are no up-to-date articles published which can provide an overview of pharmacological effects of the genus Hibiscus. Therefore, the main objective of the review article is to provide a systematic comprehensive summary of traditional uses, phytochemistry and pharmacology of the genus Hibiscus and to build up a correlation between its traditional ethano-botanical uses and pharmacological activities so as to find some advanced research opportunities in this field. The given information on the ethano-botanical uses, phytoconstituents and various medicinal properties of the genus Hibiscus was gathered from the online scientific databases through search in Google, Google Scholar, Science Direct, NCBI, Pubmed, Springer Link, Research Gate by using some keywords as. Besides these websites other published literature and unpublished Ph.D. thesis and M.Sc. dissertation were also consulted. Previously conducted research revealed that the genus contains good amount of phytoconstituents such as antioxidants, phytosterols, saponins, lignin, essential oils, glycosides, and anthocyanins etc. Presence of these bioactive compounds in the crude extracts of the plants make it suitable for various medicinal properties like anti inflammatory, anti-diabetic, anti-obesity, anti-proliferative, anti-ulcer, hypersensitive, hypolipidemic, hepatoprotective, nephroprotective and many more. Additionally, this review article showed that mainly two species of the genus i.e. H. rosa-sinensis and H. sabdariffa have been explored for their pharmacological activities. There are few reports on some other species like H. tiliaceous, H. microanthus, H. asper, H. acetosella. This review highlights the medicinal potential of the plant Hibiscus due to its unique blend of phytochemicals. These phytoconstituents can be further assessed and subjected to clinical trials for their proper validations. Although large amount of the data regarding pharmacological effects has already been added to the existing reservoir but still potential of certain species like H. radiatus, H. hirtus, H. moschetous, H. trionum and many more is not yet unveiled and can be considered as future prospects that need to be worked out.  Graphical Abstract:

    Abstract: Background : High serumMBL level as well as polymorphisms in the mannose-binding lectin 2 (MBL2) gene resulting in MBL deficiency are involved in the mechanism of a number of non-infectious diseases such as asthma, conferring either risk or protection in different population studies. MBL being the first reactant of the MBL pathway is also a major determinant of the fate of the anaphylatoxins such as C3a and C5a, which are also pro-inflammatory mediators. The MBL2 gene polymorphisms thus control the serum levels of MBL as well as C3a and C5a. Objective : This is the first case-control study conducted in India, investigating the role of MBL2 codon 54 A/B polymorphism in asthma pathogenesis. Methods : A case-control study was performed with a total of 992 adult subjects, including 410 adult asthmatics and 582 healthy controls from regions of North India. The MBL2 codon 54 A/B polymorphism was genotyped by PCR-RFLP. Results : Statistical analysis for the codon 54 polymorphism revealed that the wild (A) allele was significantly associated with asthma with OR = 1.9, 95% CI (1.4–2.4), and p 〈 0.001. Conclusion : The MBL2 codon 54 A/B polymorphism is significantly associated with asthma and its phenotypic traits as the wild (A/A) genotype confers a significant risk towards the disease in the studied North Indian population.
