Structural Modifications of Surfactant-Assisted Alumina and Their Effectiveness for the Removal of Dyes

The current study focuses on the development of the modified surface of the alumina by anionic surfactant sodium dodecyl sulfate. The synthesized Surfactant Modified Alumina (SMA) effectively associated with dye molecules and amended their properties. The triphenylmethane (CBB) and thiazine dyes (MB) were selected as a simulated dye wastewater system. The removal was carried out by adsorption method under the optimized amount of adsorbent dosage, the concentration of adsorbate, contact time and temperature. The adsorption isotherm models like Langmuir, Freundlich and Dubinin Radushkevish were employed. The mechanism of the interaction represents the decolorized leuco dye molecules were formed after adsorption. Moreover, the thermodynamic parameters like (Delta S degrees), (Delta H degrees) and (Delta G degrees) were calculated represents the endothermic and spontaneous nature of the adsorption process. The pH at the point of zero charges (pHPZC) was determined. The photocatalytic degradation of respective dye systems was also observed. The surface morphology of (SMA) was determined by FT-IR and SEM techniques. Whereas the pseudo second order kinetics model was followed in the present system. The Pearson correlation Coefficient was conjointly applied. The removal efficiency was ascertained to be 99.50% for CBB(R-250) and 95.70% for (MB).

Thiazine Red(+) platelet inclusions in Cerebral Blood Vessels are first signs in an Alzheimer’s Disease mouse model

Strong evidence shows an association between cerebral vascular diseases and Alzheimer’s disease (AD). In order to study the interaction of beta-amyloid (A beta) plaques with brain vessels, we crossbred an AD mouse model (overexpressing amyloid precursor protein with the Swedish-Dutch-Iowa mutations, APP_SweDI) with mice expressing green fluorescent protein (GFP) under the flt-1/VEGFR1 promoter in vessels (GFP_FLT1). Our data show, that only very few A beta plaques were seen in 4-months old mice, focused in the mammillary body and in the lateral septal nucleus. The number of plaques markedly increased with age being most prominent in 12-months old mice. Thiazine Red was used to verify the plaques. Several Thiazine Red(+) inclusions were found in GFP(+) vessels, but only in non-perfused 4-months old mice. These inclusions were verified by Resorufin stainings possibly representing cerebral amyloid angiopathy. The inclusions were also seen in non-crossbred APP_SweDI but not in wildtype and GFP_FLT1 mice. In order to characterize these inclusions Flow Cytometry (FACS) analysis demonstrated that platelets were specifically stained by Thiazine Red(+), more pronounced when aggregated. In conclusion, our data show that Thiazine Red(+) inclusions representing aggregated platelets are a first pathological sign in AD before plaque development and may become important therapeutic targets in early AD.

Effect of Substituents in Hydrolyzed Cephalosporins on Intramolecular O-H center dot center dot center dot N Bond

Model molecular systems structurally similar to the transition state of the limiting step of the hydrolysis of cephalosporin antibiotics by the L1 metallo-beta-lactamase are studied. The series of fluorinated compounds show that the nature of substituents in thiazine and beta-lactam rings have a great impact on the strength of the intramolecular O-H center dot center dot center dot N hydrogen bond that determines the catalytic parameters in real biological systems. The strengthening or weakening of the O-H center dot center dot center dot N bond is registered via a quantum topological analysis of the electron density, supplemented with various bonding descriptors’ study. The obtained data are confirmed by the analysis of the vibrational frequency shift relatively to the nonfluorinated compound for the O-H stretching mode of the carboxylic group involved in the O-H center dot center dot center dot N bond formation. The absence of the monotonic dependence of the hydrogen bond strength on the donor-acceptor effects of substituents shows that considered bonding descriptors do not provide a complete understanding of the bonding mechanisms in the active center of L1 metallo-beta-lactamase.
