A methodology to engineer roughened inorganic nanostructures on zeolites by deposition and growth of metal hydroxides is reported. Pure-silica (PS) MFI and (aluminosilicate) LTA zeolite crystals are treated by solvothermal methods to deposit inorganic hydroxide (e.g., Mg(OH)2) coatings with nanoscale roughened features on the crystal surfaces in a controlled manner. Detailed characterization of...

Zeolite HOU-2 (LTA type) is prepared with the highest silica content (Si/Al = 2.1) reported for Na-LTA zeolites without the use of an organic structure-directing agent. The rational design of Si-rich zeolites has the potential to improve their thermal stability for applications in catalysis, gas storage, and selective separations.

Lipoteichoic acids (LTA) from various gram-positive bacteria, including oral streptococci such as Streptococcus sanguis, enhanced the production of hepatocyte growth factor (HGF) (scatter factor) by human gingival fibroblasts in culture, whereas lipopolysaccharides (LPS) from various gram-negative bacteria did not. In contrast, LPS induced interleukin 1 activity in human gingival epithelial cel...

OBJECTIVE Although physical activity occurs in leisure, transport, occupational and domestic domains of life, the contribution of house and garden work (HGW) to the association between total physical activity and well-being is not clear. The aim was to describe the contribution of HGW to total physical activity (TPA) in association with well-being in younger, mid-aged and older women. DESIGN ...

We read with great interest the study by Price et al., which verifies that high post-treatment platelet reactivity (HPPR) measured with a point-of-care VerifyNow assay (Accumetrics Inc., San Diego, CA, USA) is associated with post-discharge events after percutaneous coronary intervention (PCI) with drug-eluting stent (DES), including stent thrombosis. To the best of our knowledge, this is the f...

this mini review article, intends to provide the essential information about microemulsion technique as a reliable approach toward the synthesis of zeolitic nano crystallites. the strategy discussed here provides a unique, effective, and potentially general methodology to the preparation of uniform and high purity nano crystallites of template-free zeolitic materials including lta, faujasite ty...

Streptococcus pneumoniae is one of the most common Grampositive pathogens. Upon colonizing the upper respiratory tract it causes severe infections and it causes life-threatening diseases like pneumonia, bacteremia, and meningitis when it reaches the lower respiratory tract or the bloodstream,l1J thereby resulting in a high mortality rate,!2·3J As for all Gram-positive bacteria, the cell wall of...

Aims: The present study is to investigate the effect of Lipoteichoic Acid (LTA) on the secretion of MUC5AC by nasal mucosa cells, as well as the underlying mechanism. Methods: Human nasal epithelial cell line HNEpC was incubated with 10, 20 or 30 μg/ml LTA for 0-24 h. Enzyme-linked immunosorbent assay was used to determine the concentrations of secreted MUC5AC and Transforming Growth Factor (TG...

Single-nucleotide polymorphisms within the BAT1-NFKBIL1-LTA genomic region (6p21.3) and the LGALS2 gene (22q13.1), encoding a regulator for lymphotoxin-alpha, the product of the LTA gene, have been reported to be linked with the risk of myocardial infarction in Japanese. We employed nine polymorphisms from the BAT1-NFKBIL1-LTA region and one polymorphism from the LGALS2 gene, and investigated w...

BACKGROUND The Acute Respiratory Distress Syndrome (ARDS), remains a significant source of morbidity and mortality in critically ill patients. Pneumonia and sepsis are leading causes of ARDS, the pathophysiology of which includes increased pulmonary microvascular permeability and hemodynamic instability resulting in organ dysfunction. We hypothesized that N-ethylmaleimide sensitive factor (NSF)...
