In small-pore zeolite catalysts, where the size of the pores is limited by eight-ring windows, aromatic hydrocarbon pool molecules that are formed inside the zeolite during the Methanol-to-Olefins (MTO) process cannot exit the pores and are retained inside the catalyst. Hydrocarbon species whose size is comparable to the size of the zeolite cage can cause the zeolite lattice to expand during th...

Disciple‐LTA is a personal cognitive assistant to an intelligence analyst that addresses several systemic problems associated with the current analytic process related to effective analytic assistance, capturing of analytic expertise, and tutoring new analysts. Disciple‐LTA can rapidly acquire and maintain analytic expertise which currently takes years to establish, is lost when analysts separa...

Recently, LTA-Se(1–8) samples with 1–8 Se atoms per cavity (simplified unit cell, large + sodalite cage) obtained via adsorption at the temperature of ∼450 °C were reported. It was shown that single Se8 or Se12 ring are formed in LTA cavities, Se8/Se12 concentration ratio decreasing an increase loading density. Contrary, present work, using vapour ∼550 °C, we succeeded encapsulation ∼17 (LTA-Se...

We have recently confirmed that lipoteichoic acid (LTA), a major constituent of the gram-positive bacterial surface, is the endotoxin of gram-positive bacteria that induces proinflammatory molecules in a Toll-like receptor 2 (TLR2)-dependent manner. LTA is an anionic amphipath whose physicochemical properties are similar to those of lipopolysaccharide (LPS), which is found on the outer leaflet ...

In recent years, natural substances such as zeolite have been used to absorb heavy metals in soil in an attempt to decrease their availability to plants. Compared to other techniques, the use of zeolite is fast, clean, and inexpensive. This research was carried out to investigate the effects of an Iranian natural zeolite (clinoptilolite) on stabilizing Cd-contaminated soil treated with 0.01 M C...

Capsule Background: Lymphotoxin-alpha (LTA) is involved in the pathogenesis of atherosclerosis. Results: The P2Y2 nucleotide receptor (P2Y2R) recruits filamin A to activate Rho signaling upstream of LTA secretion leading to intercellular cell adhesion molecule-1 expression. Conclusion: P2Y2R regulates LTA gene activation and secretion in vascular smooth muscle cells. Significance: This suggests...

OBJECTIVE The lymphotoxin-α (LTA), as one of the mediators of inflammation, may play an important role in the pathogenesis of myocardial infarction (MI). Genetic association studies (GAS) that have investigated the association between three common polymorphisms (A252G, G10A and C804A) of the LTA gene and susceptibility to MI have produced contradictory and inconclusive results. The aim of this ...

D-Alanyl-lipoteichoic acid (D-alanyl-LTA) from Lactobacillus casei contains a poly(glycerol phosphate) moiety that is selectively acylated with D-alanine ester residues. To characterize further the mechanism of D-alanine substitution, intermediates were sought that participate in the assembly of this LTA. From the incorporation system utilizing either toluene-treated cells or a combination of m...

Minimally subcultured clinical isolates of virulent nephritogenic and nonnephritogenic Streptococcus pyogenes of the same serotype showed major differences in lipoteichoic acid (LTA) production, secretion, and structure. These were related to changes in coccal adherence to and destruction of growing human skin cell monolayers in vitro. A possible relationship between cellular LTA content and gr...

PURPOSE Lymphotoxin-Alpha (LTA) is a mediator of inflammation which may be associated with the risk of ischemic stroke (IS). Polymorphisms (-252A/G and -804C/A) in the LTA gene have been found to be associated with IS with contradictory results. The present meta-analysis aimed to provide a comprehensive account of the association of (-252A/G and -804C/A) gene polymorphisms of LTA gene with susc...
