Molecular Dynamics Simulation of RND Efflux Pumps Involved in Multidrug Resistance
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) simulation is employed to understand the conformational dynamics and functional …

In silico Bioprospection and Identification of Propitious Herbal Mitigators Against Highly Virulent Pathogenic Strains of Bacteria Like Vancomycin Resistant Enterococci
Abstract: Vancomycin resistance genes have been isolated from various strains of Enterococci, owing to the high rate of recombination and vast potential of disseminating resistant genes between Enterococcal strains. Various virulent factors contribute towards the dissemination of infections caused by such Multi-Drug Resistant (MDR) strains, ultimately leading to a devastating state of environmental contamination and cross infection. Minimizing the prevalence of these strains by multiple control efforts therefore is of paramount …

Navigating the Depths of Cancer Stem Cells: Unraveling Resistance Mechanisms and Emerging Therapeutic Strategies
Abstract: In the past few decades, comprehensive evidence has convincingly established the presence of cancer stem cells (CSCs) as a minor subset within tumors, contributing to an unusually elevated level of cellular diversity within the malignancy. CSCs are functionally identified by their capacity for self-renewal and differentiation, frequently influenced by signals from their surrounding microenvironment. The interconnected transcriptional, post-transcriptional, metabolic, and epigenetic regulatory networks govern the biological characteristics of CSCs. CSCs …

Trends of Antimalarial Resistance in Ethiopia and its Challenge on Malaria Control Program
Abstract: Antimalarial drugs resistance is one of the major obstacles for malaria control and curtails the life-span of several drugs. Resistance to well tolerated and effective antimalarial drugs such chloroquine and sulfadoxine-pyrimethamine (SP) has forced the switch of national policies to artemisinin-based combination therapy (ACT) for the treatment of falciparum malaria. The emergence of less sensitive clones of Plasmodium falciparum to the ACT drugs, shortly after its deployment, has posed a …
