Photosensitive molecules such as quinones in drugs may become activated by exposure to UV-A light (320–400 nm) of the solar spectrum and cause damages to biological materials such as amino acids, nucleic acids, lipids, etc.. 9,10-anthraquinone (AQ) and 1,4-naphthoquinone (NQ), based drugs are commonly used as antibacterial, antifungal, antiviral, antitumor and antimalarial. Synephrine (SY) is used in traditional Read More

Calcific aortic valve disease (CAVD) is the most common valvular disorder, affecting approximately 25% of the population aged over 65 years. The formation of calcific nodules on the aortic surface of the leaflets contributes to a progressive obstruction of the left ventricular outflow and leads ultimately to heart failure (Stewart et al., 1997). While CAVD has been described historically as a passive degenerative process, it has no Read More

Background The X-linked inhibitor of apoptosis (XIAP) is a promising molecular target for the design of novel anticancer drugs aiming at overcoming apoptosis-resistance of cancer cells. Recent studies demonstrated that the BIR3 domain of XIAP where caspase-9 and Smac proteins bind is an attractive site for designing small-molecule inhibitors of XIAP. Embelin, identified primarily from the Embelica ribes plant, is one such co Read More

The overlap stage is one of the most time- and space-consuming steps in de novo genome assembly. The huge size of output of Next Generation Sequencing (NGS), represented by small segments of multiple copies of the original genome, creates a serious computational challenge. The target is to find overlaps between each pair of sequences (reads) in order to build an overlap-based graph which constitutes the input for the a Read More

Background Duncan-Hewitt and Austin (2005) argue that pharmacist education has shifted from apprenticeship into higher education. This shift created “a gap between education theory and education practice”. Therefore, the role education theory plays in educational practices should be examined. Objectives Analyze the PharmD programme at QU through the lens of a theory-informed CoPF comprising of six elements: e Read More

Background Cystic fibrosis (CF) is a genetic disease affecting 70,000 individuals worldwide and results from mutations in the gene that encodes the cystic fibrosis transmembrane conductance regulator (CFTR). In the lungs, the mucociliary clearance mechanism is impaired and the airways of CF patients are often colonized by bacteria, yeasts and filamentous fungi. Among clinically significant fungi, Candida spp. are the most com Read More

Introduction This study was held on the in vitro tests for the bacteriophages and their efficiency comparing with the antibiotics susceptibility in destroying bacteria. Because the development of the resistance to chemotherapeutic agents is becoming an increasing problem. Antimicrobial phage therapy trials have demonstratedphage infection of the increasing incidence resistantbacteria against most or all known antibioti Read More

The key challenge with Epidemics includes its ability to spread rapidly and impact several large communities with high fatality rates. These characteristics make it difficult and very expensive to manage epidemics once it has broken out. History is replete with several cases of epidemic out breaks spreading from the point of origin and being transmitted to other areas resulting in the deaths of several thousands and in so Read More

Background & objective In order to survive the effects of the stress conditions, such as hypoxia and glucose starvation (GS) that exist in a tumor microenvironment, the regulatory mechanisms that control metabolism in cancer cells undergo change so that sufficient energy sources are available for proliferation, migration and invasion - thus facilitating metastasis. Via what is referred to as The Warburg Effect cancer cell Read More
