Analysis of the length distribution of murein glycan strands inftsZandftsImutants ofE. coli [PDF]
The chain length distribution of murein glycan strands was analyzed in wild-type cells and in cells in which preseptal and/or septal murein synthesis was prevented in ftsZ84 and ftsI36 mutants of E. coli. This revealed a significant change in glycan chain lengths in newly synthesized murein associated with inactivation of the ftsZ gene product but not ...

The decreased affinity to β-lactams in Haemophilus influenzae is usually caused by specific alterations in penicillin-binding protein 3 due to varieties of substitutions in ftsI gene. This study aimed to characterize the polymorphism of ftsI gene in 19 H.

Mutant ftsI genes in the emergence of penicillin-binding proteinmediated β-lactam resistance in Haemophilus influenzae in Norway [PDF]
The most important mechanism for beta-lactam resistance in beta-lactamase-negative ampicillin-resistant (BLNAR) isolates of Haemophilus influenzae is the alteration of penicillin-binding protein 3 (PBP3) as a result of ftsI gene mutations. The present study aimed to map PBP3 alterations and to determine the correlation to beta-lactam resistance in ...

Efficacy of Simulated Cefditoren versus Amoxicillin-Clavulanate Free Concentrations in Countering Intrastrain ftsI Gene Diffusion in Haemophilus influenzae [PDF]
ABSTRACT This study explores the effects of cefditoren (CDN) versus amoxicillin-clavulanic acid (AMC) on the evolution (within a single strain) of total and recombined populations derived from intrastrain ftsI gene diffusion in β-lactamase-positive (BL + ) and β-lactamase-negative ...

Numerical study on the performance of pintle controlled solid rocket motor based on fluid-thermal-structure interaction [PDF]
To accurately predict the performance of pintle controlled solid rocket motors (PCSRM), a fluid-thermal-structure interaction (FTSI) numerical model is developed. First, by comparing the FTSI method, conventional numerical method, and empirical formulas,
