Semi-permanent cationic coating for protein separations

Capillary electrophoresis has been used extensively for protein separations, but interactions of proteins with the negative charge on the surface of fused silica capillary create band broadening and diminish the separation efficiency. Coatings developed to mask the negative charge of the capillary affect the electroosmotic flow. The method presented in this work addresses these concerns through the use of a two-layer coating of a semi-permanent phospholipid substrate and cetyltrimethylammonium bromide (CTAB). When used alone, phospholipid coating suppresses the electroosmotic flow but cannot be used to simultaneously separate anionic and cationic proteins. When used alone, CTAB creates a dynamic coating that facilitates the separation of cationic proteins with good efficiency, but reduces the separation efficiency of anionic proteins. The use of a hybrid phospholipid-CTAB surface coating alleviates protein adsorption, as demonstrated through a comparison of protein separations obtained with a bare fused silica capillary. The hybrid phospholipid-CTAB surface enables high efficiency separations of cationic and anionic proteins simultaneously. This work verifies the role of the hydrophobic tail of CTAB in developing a stable coating with an electroosmotic flow of 3.14 x 10(-4) cm(2) V-1 s(-1) (n = 10) from the cathode to the anode at a pH of 7. The coating yields a stable electroosmotic flow even after 2 h of flushing with background electrolyte devoid of CTAB (n = 3) and six consecutive protein injections with no flush sequence between runs. The coating can be used with background electrolytes with pH values ranging from 4 to 8 while maintaining 1% RSD (n = 10) in the electroosmotic flow for each background electrolyte. Six model proteins, lysozyme, ribonuclease A, alpha-chymotrypsinogen A, enolase, transferrin, and alpha-1-antitrypsin, with pI values ranging from 4.4 to 11 were used to demonstrate the stability of the phospholipid-CTAB coating, the lack of protein interaction with the wall, and the utility of the coating for the separation of proteins of similar isoelectric points and of protein isoforms.

Effects of ionic liquid pretreatment on pyrolysis characteristics of a high-sulfur bituminous coal

Four different ionic liquids (ILs) were used to identify their extraction properties on high-sulfur bituminous coal. And the effect of ILs pretreatment on pyrolysis characteristic was investigated in a fixed-bed reactor. The imidazolium-based ILs used namely: 1-butyl-3-methyl-imidazolium chloride ([Bmim]Cl), 1-butyl-3-methyl-imidazolium bromide ([Bmim]Br), 1-butyl-3-methylimidazolium hydrogen sulfate ([Bmim]HSO4), 1-butyl-3-methyl-imidazolium tetrafluoroborate ([Bmim]BF4). All the selected ILs exhibited extraordinary extraction ability for oxygen-containing compounds, mainly furans and ethers. Among them, [Bmim]Cl got the highest extraction yields of 20.82% and performed selective extraction ability for sulfur-containing compounds with a relative content of 5.10% in light oils. Compared with pyridine pretreated coal (R-PY), the yields of CO and CO2 in pyrolysis gas showed increase trend when coal pretreated by ILs (R-ILs). The relative contents of tricyclic and larger PAHs, sulfur-containing compounds, and oxygen-containing compounds in tar from pyrolysis of [Bmim]Cl and [Bmim] Br treated coal increased significantly than R-PY tar, while phenols got decreased. High carbon number components from R-ILs tar reduced dramatically compared with R-PY tar, which was conducive to the upgrading of tar, after pretreated with ILs, the sulfur content was reduced. The crosslinks between coal macromolecules structure were destroyed after pretreated by ILs, and the pyrolysis products distribution had evident change. The oil phase yield got a substantial increase while [Bmim]Cl obtained highest oil yield of 24.89%.

Synthesis, Modification, and Characterization of CuO/ZnO/ZrO2 Mixed Metal Oxide Catalysts for CO2/H-2 Conversion

CuO/ZnO/ZrO2 catalyst systems were synthesized in different ways and comprehensively characterized in order to study synthesis-to-property relations. A series of catalyst samples was prepared by coprecipitation, one-pot synthesis, and wet impregnation. The coprecipitation of multicomponent precipitates is usually a preliminary stage for preparation of mixed oxide catalysts. Cetyltrimethylammonium bromide (CTAB) was used in the surfactant-supported coprecipitation to improve the structural or textural characteristics of the catalytic samples. In the one-pot synthesis, all necessary components are simultaneously converted by evaporation from solutions into solids. During the wet impregnation, zirconium hydroxide is loaded with metal salts. After thermal treatment, all samples formed pure metal oxide forms, which was confirmed by XRD. The specific surface area of the investigated samples and their porous texture were determined by nitrogen adsorption. The reducibility of metal oxides and the kind of CuO phase was characterized by temperature-programmed reduction (TPR), and the surface acid properties by temperature-programmed ammonia desorption (TPAD). The CuO/ZnO/ZrO2 sample with the highest amount of strong acid sites is characterized by the formation of large CuO particles combined with the worst reducibility so that potentially catalytic active Cu/CuO pairs can be formed. One catalyst system was further characterized by in situ diffuse reflection Fourier transform infrared spectroscopy (DRIFTS) to identify surface intermediate species, which may occur during the conversion of CO2/H-2 to methanol.

Dumbbell-Like Silica Coated Gold Nanorock and Their Plasmonic Properties

Silica coated gold nanorods (GNRs@SiO2) with dumbbell:like morphology allowing dual functionalization in an individual nanostructure have attracted great attention for applications such as sensing and biological imaging. We report a detailed study on the feasibility of controlling the morphology of silica coating on GNRs. The morphology of the silica shell can be either cylindrical or dumbbell shaped. With constant GNR concentration, the ratio of hexadecyl-trimethylammonium bromide (CTAB) and tetraethylorthosilicate (TEOS) concentrations is the key to determine the amount of available TEOS for silica deposition on the GNR since the TEOS will diffuse toward the surface of GNRs. The effect of morphologies on surface-enhanced Raman scattering (SERS) performance was also investigated, and we found that the dumbbell morphology of silica coated gold nanorods has the most significant SERS enhancement. Our study is significant in terms of the capability to control the dumbbell morphology of silica coated gold nanorods, which can eventually broaden the application of these plasmonic nanomaterials.

Magnetic properties and hyperthermia behavior of iron oxide nanoparticle clusters

In this study, Iron Oxide nanoparticle clusters have been synthesized utilizing individual Fe3O4 nanoparticles with different sizes as building blocks. The synthesis was accomplished by encapsulation of the individual Fe3O4 nanoparticles in an oil in water emulsion via hydrophobic interactions between cetyltrimethylammonium bromide (CTAB) and the nanoparticle’s surface aliphatic capping agents. It has been observed that the time, temperature and CTAB concentration were three crucial factors for controlling the size, shape and collective behavior of the clusters. Powder X-Ray Diffraction study shows that both individual Fe3O4 and the corresponded nanoparticle clusters have the Fe3O4 cubic spinel structure. Dynamic Light Scattering (DLS) shows that the hydrodynamic diameter of cluster is in the range of 100 to 200 nm. Transmission electron microscopy (TEM) images illustrate that different sizes of clusters can be effectively synthesized by using different concentration of CTAB and the results are consistent with the DLS values. Magnetic measurements show that the saturation magnetization of clusters can be changed from 56.7 emu/g to 70.1 emu/g by just changing the size of primary individual nanoparticles from 7.1 nm to 11.5 nm. Also, the blocking temperatures for Fe3O4 clusters were increased to higher temperatures which confirms the stronger collective behavior in the case of larger nanoparticles. The magnetic hyperthermia behavior of the clusters has also been studied, and the data shows that the Specific Absorption Rate (SAR) values are increased by both the clustering and the size of the primary nanoparticles.

If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 106-37-6, in my other articles. Formula: C6H4Br2.

Interleukin-8 associated with chemosensitivity and poor chemotherapeutic response to gastric cancer

Background: Gastric cancer (GC) patients have been found to have developed chemotherapy resistance that has resulted in a lowering of their overall survival rates. Interleukin-6 (IL-6) and interleukin-8 (IL-8) could be responsible as the predictive biomarkers in monitoring drug resistance. We have developed a protocol to monitor drug treatment by testing ex vivo chemosensitivity and cytokine levels of primary gastric cultures obtained from endoscopic biopsies. Methods: We studied 49 patients with distal GC who underwent primary surgical resection between June 2014 and December 2016 in the northern endemic region of Thailand. The clinical and pathological data of patients were recorded, and the cancer sub-type was classified. The correlation of cytokine IL-6 and IL-8 protein expression levels and chemotherapy sensitivity in primary gastric cultures was investigated. Endoscopic biopsies were collected before and/or after chemotherapy treatment followed by FOLFOXIV regimen (oxaliplatin + 5-FU/leucovorin). The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyftetraz.olium bromide (MTF) assay was performed to examine cx vivo chemosensitivity to cisplatin, oxaliplatin, 5-fluorouracil (5-FU) and irinotecan. Enzyme-linked immunosorbent assay (ELISA) was performed to investigate cytokine levels. Results: Ex vivo drug treatment of 49 primary gastric cultures from naive patients revealed a significant correlation between basal levels of IL-8 and chemosensitivity to cisplatin (P=0.001) and oxaliplatin (P=0.001). IL-8 protein expression levels were significantly decreased in the early phase after cisplatin and oxaliplatin treatments leading to an increase in cell sensitivity to drug treatments. Among 49 patients, 11 patients were classified as partial or poor responders after drug interventions, in which case, second endoscopic biopsies were performed for determination of chemosensitivity and cytokine levels. The results demonstrated significant decreases in sensitivity to cisplatin (P=0.(49) and oxaliplatin (P=0.014), meanwhile IL-8 protein expression levels were significantly increased by P=0.0423 in both drug treatments. There was no correlation of IL-6 and drug resistance when treatments of the primary gastric cultures involved each of the four chemotherapeutic drugs (P=0.0663). Conclusions: Upregulation of IL-8 after drug intervention might be useful as predictive biomarker in monitoring drug resistance in GC patients; however, this needs to be confirmed among a larger number of patients and with control groups that are properly age-paired. The established primary gastric culture could serve as a valuable tool for chemotherapy screening, while the repeated usage of platinum drugs may result in drug resistance via upregulation of IL-8 levels.

Biocompatibility and mechanical properties evaluation of chitosan films containing an N-acylhydrazonic derivative

The N-acylhydrazone subunit is considered a privileged structure in medicinal chemistry for its importance in pharmaceutical research. Also, alternative methods to deliver these molecules have a great pharmaceutical interest. Therefore, the objective of this work was to encapsulate JR19, an N-acyl hydrazone subunit, into chitosan films and evaluate several properties relevant for transdermal delivery, including biocompatibility using in vitro tests. CHI + JR19 film demonstrates greater strength, flexibility, water absorption capacity, low contact angle and higher surface roughness when compared to CHI. Agar diffusion and 3-(4,5-dimethyl)-2,5-diphenyl tetra-zolium bromide (MTT) assay show the absence of cytotoxicity and the higher cell viability for CHI + JR19 films. Therefore, the addition of JR19 in the system positively influenced mechanical properties and granted better compatibility with biological environments, showing the potential to treat skin inflammation.
