Many human pathogens, including Corynebacterium diphtheriae, the causative agent of diphtheria, use host compounds such as heme and hemoglobin as essential iron sources. In this study, we examined the Corynebacterium hmu hemin transport region, a genetic cluster that contains the hmuTUV genes encoding a previously described ABC-type hemin transporter and three additional genes, which we have de...

We evaluated hexadecyltrimethylammonium bromide (HTAB) for liquid crystals (LCs) in layered ITO cells with various cell gap conditions. HTAB is a surfactant that can self-align vertically on the surface of indium tin oxide (ITO) substrates and induce homeotropic alignment LC molecules. For implementing RF devices LCs, we should consider limitations caused by design conditions which are differen...

Corynebacterium diphtheriae utilizes hemin and hemoglobin (Hb) as iron sources during growth in iron-depleted environments, and recent studies have shown that the surface-exposed HtaA protein binds both hemin and Hb and also contributes to the utilization of hemin iron. Conserved (CR) domains within HtaA and in the associated hemin-binding protein, HtaB, are required for the ability to bind hem...

INTRODUCTION S. aureus is a Gram positive bacterium which is responsible for a wide range of infections. This pathogen has also the ability to adhere to biotic or abiotic surface such as central venous catheter (CVC) and to produce a biofilm. The aim of this study was to evaluate the effect of hexadecyltrimethyl ammonium bromide (HTAB) and Hexadecylbetainate chloride (HBC) on Staphylococcus aur...

Hybrid logic is a formalism that is closely related to both modal logic and description logic. A variety of proof mechanisms for hybrid logic exist, but the only widely available implemented proof system, HyLoRes, is based on the resolution method. An alternative to resolution is the tableaux method, already widely used for both modal and description logics. Tableaux algorithms have also been d...

In this study, the effects of hydrochloric acid (HCl) and acetic (HAc) modification on hexadecyl trimethyl ammonium bromide (HTAB) K+ adsorption characteristics a natural zeolite were investigated. Electrokinetic evaluations showed that HCl had more prominent effect zeta potential compared to HAc. Additionally, pH regulation behavior acid-modified samples was found differ from sample it in agre...

Abstract Background The use of registries is increasingly common in HTA as interest grows the observational data to complement trial and optimize access new technologies. Registry quality has been criticized, leading reluctance embed their HTA. During EUnetHTA Joint Action 3 network produced a draft standard tool assess registry quality. Methods development phase included: analysis current by b...

the influences of anionic sodium dodecylsulfate (sds) and cationic hexadecyltrimethylammonium bromide (htab) surfactants on the incorporation and distribution of barium hexaferrite nanoparticles in the electrodeposited cofe-bafe12o19 composite thin films were studied. sulphate bathes with natural ph containing 0 to 2 g/l surfactants were used for electroplating at room temperature. field emissi...

To reduce the shortcomings of existing filtering assistance, talc was modified by a two-step method. In first step, talcum powder heated microwave in acid solution. second stirred with Hexadecyl Trimethyl Ammonium Bromide (HTAB) solution for optimum time under an temperature. The temperature, and amount HTAB were investigated batch membrane filtration experiments kaolin suspension. effects new ...
