Synthetic lethality is a genetic interaction wherein two otherwise nonessential genes cause cellular inviability when knocked out simultaneously. Drugs can mimic genetic knock-out effects; therefore, our understanding of promiscuous drugs, polypharmacology-related adverse drug reactions, and multi-drug therapies, especially cancer combination therapy, may be informed by a deeper understanding o...

Patients with HIV-1 immune-related thrombocytopenia (HIV-1–ITP) have a unique Ab against platelet GPIIIa49-66 capable of inducing oxidative platelet fragmentation in the absence of complement. HIV-1– seropositive drug abusers are more prone to develop immune thrombocytopenia than non–drug abusers and have a higher coinfection with hepatitis C virus (HCV) than non–drug abusers (90% vs 30%). Mole...

BACKGROUND Parasite lactate dehydrogenase (pLDH) is extensively employed as malaria rapid diagnostic tests (RDTs). Moreover, it is a well-known drug target candidate. However, the genetic diversity of this gene might influence performance of RDT kits and its drug target candidacy. This study aimed to determine polymorphism of pLDH gene from Iranian isolates of P. vivax and P. falciparum. METH...

Drug like methotrexate were used in the present study because of dual importance, both for clinicians as well as an interest of basic scientists. Methotrexate, an antineoplastic agent is used for malignant as well as non malignant conditions and become teratogenic & mutagenic in nature. They prevent cell proliferation by incorporated into DNA during the "S"phase of the cellcycle and inhibit rap...

Lower bound Here we describe the densities on the two manifolds M1 and M2. There are two sets of interest to us: W1 = M1 \M2 which corresponds to the two “holes” of radius 4τ in the annulus, and W2 = M2\M1 which corresponds to the d-dimensional piece added to smoothly join the inner pieces of the two annuli in M2. By construction, vol(W1) = 2vd(4τ) d where vd is the volume of the unit d-ball. v...

Staphylococcus aureus is one of the most common hospital acquired infections. It colonizes immunocompromised patients and with the number of antibiotic resistant strains increasing, medicine needs new treatment options. Understanding more about the proteins this organism uses would further this goal. Hypothetical proteins are sequences thought to encode a functional protein but for which little...

Bioinformatic analysis can not only accelerate drug target identification and drug candidate screening and refinement, but also facilitate characterization of side effects and predict drug resistance. High-throughput data such as genomic, epigenetic, genome architecture, cistromic, transcriptomic, proteomic, and ribosome profiling data have all made significant contribution to mechanismbased dr...

objective: crispr/cas9 technology provides a powerful tool for targeted modification of genomes. in this system, a donor dna harboring two flanking homology arms is mostly used for targeted insertion of long exogenous dna. here, we introduced an alternative design for the donor dna by incorporation of a single short homology arm into a circular plasmid. materials and methods: in this experiment...

modeling and simulation techniques are now widely used alongside with their experimental counterparts in order to complement them, or sometimes to bring first insights into the possible outcome of experiments. “modeling” is a general word that could encompass a wide range of methods that could be applied to a variety of subjects and problems. here, the use of selected molecular modeling methods...

Drug designing and molecular dynamic studies were an intense, lengthy and an inter-disciplinary venture. At present, a new approach towards the use of computational chemistry and molecular modeling for in-silico drug design. Computational in-silico drug design skills are used in bioinformatics, computational biology and molecular biology. Drug designing using in-silico methods is cost effective...
