INVESTIGATION OF RANGES AND FREQUENCY OF MUTATIONS IN THE embB GENE IN MYCOBACTERIUMTUBERCULOSIS ASSOCIATED WITH RESISTANCE TO ETHAMBUTOL USING REAL-TIME POLYMERASE CHAINREACTION

Туберкулез и болезни лёгких, 2017
Based on real-time allele-specific polymerase chain reaction, the ranges of potential mutations in codons of 306 and 405 of the embBgene in Mycobacterium tuberculosis associated with resistance to ethambutol were investigated.

Identification and structural characterisation of a partially arabinosylated lipoarabinomannan variant isolated from a Corynebacterium glutamicum ubiAmutant [PDF]

, 2007
Arabinan polysaccharide side-chains are present in both Mycobacterium tuberculosis and Corynebacterium glutamicum in the heteropolysaccharide arabinogalactan (AG), and in M. tuberculosis in the lipoglycan, lipoarabinomannan (LAM).

Dynamic mobility and handover management in software‐defined networking‐based fifth‐generation heterogeneous networks

International Journal of Network Management, Volume 35, Issue 1, January/February 2025.
This article proposes an optimal next cell selection technique for users in the software‐defined heterogeneous network to tackle the challenges of handover and mobility management. The technique uses linear programming (LP) to facilitate optimal cell selection and reduce the number of user handovers based on multiple parameters, including user ...

Computational analyses of drug resistance mutations in katG and emb complexes in Mycobacterium tuberculosis

Proteins: Structure, Function, and Bioinformatics, Volume 93, Issue 1, Page 359-371, January 2025.
Abstract The number of antibiotic resistant pathogens is increasing rapidly, and with this comes a substantial socioeconomic cost that threatens much of the world. To alleviate this problem, we must use antibiotics in a more responsible and informed way, further our understanding of the molecular basis of drug resistance, and design new antibiotics ...

Frequency of mutational changes in the embB among the ethambutol-resistant strains of Mycobacterium tuberculosis in Iran

Journal of Infection in Developing Countries, 2016
Introduction: Early detection of drug resistant tuberculosis is one of the main priorities of TB control program. Ethambutol (EMB) is a first-line anti-TB drug that is effective for preventing treatment failures caused by Mycobacterium tuberculosis ...

A bijection between type D_n^{(1)} crystals and rigged configurations

, 2004
Hatayama et al. conjectured fermionic formulas associated with tensor products of U'_q(g)-crystals B^{r,s}. The crystals B^{r,s} correspond to the Kirillov--Reshetikhin modules which are certain finite dimensional U'_q(g)-modules.
