There are over 600 million people worldwide covering Asian and Oceanic countries including India have the habit of chewing areca nut as masticator in different forms. Arecoline (C(8)H(13)NO(2)) has been reported as one of the abundant constituents of areca nut. A good number of scientific publications have made Arecoline responsible for oral cancer. Based(More)
INTRODUCTION Sharing traditional knowledge with the scientific community could refine scientific approaches to phytochemical investigation and conservation of ethnomedicinal plants. As such, integration of traditional knowledge with scientific data using a single platform for sharing is greatly needed. However, ethnomedicinal data are available in(More)
Cervical cancer is the second largest form of cancer to infest the leading cause of death in women worldwide. There are many causes of cancer but viruses are the most common among them. Human papillomaviruses (HPVs) are found to be the causative organism in almost 99.7% of the cases. HPV16 is the most frequent HPV type in malignant neoplastic growth in(More)
Therapeutic failures against diseases due to resistant Gram-negative bacteria have become a major threat nowadays as confirmed by surveillance reports across the world. One of the methods of development of multidrug resistance in Escherichia coli and Pseudomonas aeruginosa is by means of RND efflux pumps. Inhibition of these pumps might help to combat the(More)
Despite availability of preclinical report about antidiabetic activity of the molecule Scoparic Acid D isolated from Scoparia dulcis L. no clinical trial has reported to be initiated possibly because of the fact that molecular mechanism of hypoglycemic effect of the molecule was not explained properly. Considering the reported hypoglycemic potential of the(More)
The advent of Multi Drug Resistant (MDR) strain of Mycobacterium tuberculosis (TB) necessitated search for new drug targets for the bacterium. It is reported that 3.3% of all new tuberculosis cases had multidrug resistance (MDR-TB) in 2009 and each year, about 0.44 million MDR-TB cases are estimated to emerge and 0.15 million people with MDR-TB die. Keeping(More)
A major threat to the world is the emergence of antibiotic resistant bacteria, which has rendered previously susceptible drugs useless and increased the rate of therapeutic failures. Shigella species, which are the causative organism of Shigellosis, were earlier susceptible to ampicillin, chloramphenicol, co-trimoxazole and nalidixic acid but now they have(More)
Tuberculosis (TB) is known to mankind as one of the most pervasive and persistent of diseases since the early days of civilization. The growing resistance of the causative pathogen Mycobacterium tuberculosis to the standard drug regimen for TB poses further difficulty in its treatment and control. Screening of novel plant-derived compounds with promising(More)
The original prospective of this research is to find out the antibacterial activity of Cassia javanica L. in combination with Vancomycin against some multi drug resistant Staphylococcus aureus hospital isolates. Minimum inhibitory concentration for each extract of Cassia javanica L. was determined by agar dilution and broth macrodilution method.(More)
AIM AND OBJECTIVE Overexpression of efflux pumps belonging to the Resistance Nodulation cell Division (RND) family is the most important intrinsic resistance mechanism of Pseudomonas aeruginosa. Hence, it is imperative to identify suitable efflux pump inhibitors (EPI) that can lead to increased intracellular concentration of antibiotics by blocking the(More)
