Redefining the bacterial Type I protein secretion system.

Type I secretion systems (T1SS) are versatile molecular machines for protein transport across the Gram-negative cell envelope. The archetypal Type I system mediates secretion of the Escherichia coli hemolysin, HlyA. This system has remained the pre-eminent model of T1SS research since its discovery.

Direct continuous electromyographic control of a powered prosthetic ankle for improved postural control after guided physical training: A case study.

Despite the promise of powered lower limb prostheses, existing controllers do not assist many daily activities that require continuous control of prosthetic joints according to human states and environments. The objective of this case study was to investigate the feasibility of direct, continuous electromyographic (dEMG) control of a powered ankle prosthesis, combined with physical therapist-guided training, for improved standing postural control in an individual with transtibial amputation. Specifically, EMG signals of the residual antagonistic muscles (i.

Analysis of Selection Methods to Develop Novel Phage Therapy Cocktails Against Antimicrobial Resistant Clinical Isolates of Bacteria.

Antimicrobial resistance (AMR) is a major problem globally. The main bacterial organisms associated with urinary tract infection (UTI) associated sepsis are and along with species. These all have AMR strains known as ESBL (Extended Spectrum Beta-Lactamase), which are featured on the WHO priority pathogens list as "critical" for research.

The Effect of Oxygen Availability on Bacteriophage Infection: A Review.

Bacteriophages offer a viable solution to addressing the global issue of bacterial resistance to antimicrobials. Although knowledge of bacteriophages has increased greatly since their discovery in 1915, a significant amount of what is currently known is based on studies conducted in model conditions and aerobic environments. There are a variety of environments in which bacteriophages could be applied to successfully replace or supplement antimicrobials in agriculture, food production, and human medicine where the amount of oxygen is limited.
