Rotation-restricted strategy to synthesize high molecular weight polyethylene using iminopyridyl nickel and palladium catalyst

Most of the iminopyridyl Ni (II) and Pd (II) catalysts are reported to oligomerize ethylene or yield very low molecular weight polyethylene. Moreover, the molecular weight of product is not sensitive to ligand sterics. In this contribution, we demonstrate that the bulky rotation-restricted substituents incorporated into iminopyridyl Ni (II) and Pd (II) catalysts that provide the right orientation are highly effective in retarding the chain transfer. Thus, (2,6-bis(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)-4-methylphenyl)-1-(pyridin-2-yl)methanimine nickel (II) bromide (Ni3) and (2,6-bis(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)-4-methylphenyl)-1-(pyridin-2-yl)methanimine palladium (II) methyl chloride (Pd3) with the phenyl substituents fixed in the diarylmethyl moiety produce polyethylene or functionalized polyethylene (ethylene-MA copolymer) with high M-n values up to 2.5 x 10(4) g mol(-1), while allowing the high MA incorporation (3.2%-13.8%). In addition, the effects on the (co)polymerization behavior as a function of rotation-restricted substituent variations (free rotation, restricted rotation and fixation) were systemically studied. As a result, various molecular weight polyethylene and ethylene-MA copolymer with high MA incorporation ratio were also obtained in this system.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2032-35-1. HPLC of Formula: C6H13BrO2.

Meltblown Polylactic Acid Nanowebs as a Tissue Engineering Scaffold

Polylactic acid (PLA) nanofiber nonwovens have recently come under more vigorous investigation for their use as tissue engineering scaffolds owing to its ability to mimic the physical properties of naturally occurring human extracellular matrix in a variety of host tissues. Currently, the majority of available research on PLA nanowebs has focused on their creation through electrospinning. The goal of this study was to evaluate meltblown nonwoven webs made of nanodiameter PLA fibers for their application as a tissue engineering scaffold. Meltblown PLA fabrics were produced with a variety of different crystallinities, tensile moduli, and pore diameters. One fabric with mechanical properties similar to human dermis was selected as a scaffold to study attachment, proliferation, and migration of human dermal fibroblasts over 1, 3, 7, and 14 days without the use of additional cell adhesion molecules. The 3-(4,5-dimethylthiazol-2-yl)-diphenyltetrazolium bromide assay showed good proliferation from day 1 to 3 (P = 0.026) and up to 7 days of culture (P = 0.005) but without increase from day 7 to 14. Electron microscopy demonstrated adequate cellular attachment and surface migration at 1, 3, 7, and 14 days. Finally, confocal microscopy was used to investigate cellular penetration into the scaffolds. The investigation found that cells were able to penetrate fully through the thickness of the scaffold. The successes of this initial experiment are promising and confirm that meltblown nanofiber nonwovens are a viable avenue for tissue engineering scaffolds. Hopefully, these conclusions will open the door for others to pursue research in this exciting field.

Supramolecular Assemblies of Multi-Charged Cyclodextrins

As a class of macrocyclic host with excellent water solubility, low biotoxicity and high charge density, multi-charged cyclodextrins have been extensively studied because they can interact with organic/inorganic/biological molecules through multiple synergistic forces such as the hydrophobic cavities and electrostatic interactions to construct the smart supramolecular assemblies with stable topology, functional diversity and stimulus responsiveness. The latest research progress of pH-, photo-, enzyme-, redox-, magnetic- and multi-stimulus responsive smart supramolecular assemblies, which are constructed by typical positively/negatively charged and amphiphilic multi-charged cyclodextrins including their application in the fields of drug delivery, controlled release and sensory detection is introduced, and the challenges and future developments of multi-charged cyclodextrin smart supramolecular assemblies are discussed.

Label-free, rapid, and sensitive detection of carboxylesterase using surfactant-doped liquid crystal sensor

Carboxylesterases (CES) has been regarded as a most effective biomarker candidate of the hepatoma cells and fruitfully used in the early detection. For this reason, establishing a reliable and simple system to detect CES has become attractive in the practical applications of medical diagnosis and treatment. In this study, a novel strategy for monitoring CES based on the aqueous/liquid crystals (LCs) interface was reported. A cleavable surfactant, N-octadecyloxycarbonylmethyl-N, N, N-trimethylammonium bromide (OTB) was synthesized and utilized to control the orientation of 4-cyano-4′-pentylbiphenyl (5CB) molecules on aqueous/LCs interface. The formation of OTB self-assembly monolayer promotes the alignment of the LCs, on average, normal to the surface (homotropic), whereas a corresponding black image was observed by polarized optical microscopy (POM). Subsequently, the doping of CES induces the hydrolysis of the OTB, resulting in the disruption of OTB monolayer and thereby an obvious dark-to-bright transition in the optical response. This optical transition provides a quick and easy way of detecting CES. OTB-decorated LC surfaces have been developed as a sensor, with a detection limit of 18 U/L for CES detection. As-made LCs-based sensor exhibits superior detection sensitivity and specificity towards the detection of CES, as well as the excellent long-term stability. The preliminary results shows success in sensing CES from the urine samples, which also suggests the promising detection performance of LCs sensor in practical situations. In summary, the as-prepared CES sensor, offers several advantages along with its cost-effective and easy fabrication procedure, demonstrates its potential for medically assisted therapy in human samples.

Cyclic amidine hydroiodide for the synthesis of cyclic carbonates and cyclic dithiocarbonates from carbon dioxide or carbon disulfide under mild conditions

Hydroiodides of amidines can catalyze the reaction of carbon dioxide and epoxides under mild conditions such as ordinary pressure and ambient temperature, and the corresponding five-membered cyclic carbonates were obtained in high yields. The reaction of epoxide with carbon disulfide was also examined under the same conditions. Detailed investigation showed that the catalytic activity was highly affected by the counter anions of the amidine salts; the iodides were effective catalysts for both of the reaction of epoxide with carbon dioxide and carbon disulfide, whereas the bromide, chloride and fluoride counterparts exhibited almost no catalysis.

Fucosylated umbilical cord blood hematopoietic stem cell expansion on selectin-coated scaffolds

Despite the advantages of transplantation of umbilical cord blood’s (UCB’s) hematopoietic stem cells (uHSCs) for hematologic malignancy treatment, there are two major challenges in using them: (a) Insufficient amount of uHSCs in a UCB unit; (b) a defect in uHSCs homing to bone marrow (BM) due to loose binding of their surface glycan ligands to BM’s endothelium selectin receptors. To overcome these limitations, after poly l-lactic acid (PLLA) scaffold establishment and incubation of uHSCs with fucosyltransferase-VI and GDP-fucose, ex vivo expansion of these cells on selectin-coated scaffold was done. The characteristics of the cultured fucosylated and nonfucosylated cells on a two-dimensional culture system, PLLA, and a selectin-coated scaffold were evaluated by flow cytometry, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, colony-forming unit (CFU) assay, and CXCR4 expression at the messenger RNA and protein levels. According to the findings of this study, optimized attachment to the scaffold in scanning electron microscopy micrograph, maximum count of CFU, and the highest 570nm absorption were observed in fucosylated cells expanded on selectin-coated scaffolds. Furthermore, real-time polymerase chain reaction showed the highest expression of the CXCR4 gene, and immunocytochemistry data confirmed that the CXCR4 protein was functional in this group compared with the other groups. Considered together, the results showed that selectin-coated scaffold could be a supportive structure for fucosylated uHSC expansion and homing by nanotopography. Fucosylated cells placed on the selectin-coated scaffold serve as a basal surface for cell-cell interaction and more homing potential of uHSCs. Accordingly, this procedure can also be considered as a promising technique for the hematological disorder treatment and tissue engineering applications.

Synthesis, characterization and photophysical properties of novel thiazole substituted pyridine derivatives

Three series of isomeric 2-pyridyl 4-aryl thiazoles have been synthesized by reacting 2/3/4-pyridine thioamides derived from the corresponding nitrites with various 4-substituted phenacyl bromides using Hantzsch thiazole synthesis. Amongst the three isomeric series, 2-pyridyl and 4-pyridyl isomers are found to exhibit better photophysical properties than 3-pyridyl series. 4-Pyridyl isomer with methoxy substituent on phenyl ring is found to exhibit high luminescence quantum yield. The relationship between the structure and the photophysical properties have been studied using DFT calculations.

Mustard Gold in the Oleninskoe Gold Deposit, Kolmozero-Voronya Greenstone Belt, Kola Peninsula, Russia

The Oleninskoe intrusion-related gold-silver deposit is the first deposit in the Precambrian of the Fennoscandian Shield, where mustard gold has been identified. The mustard gold replaces kustelite with impurities of Sb and, probably, gold-bearing dyscrasite and aurostibite. The mosaic structure of the mustard gold grains is due to different orientations and sizes of pores in the matrix of noble metals. Zonation in the mustard gold grains is connected with mobilization and partial removal of silver from kustelite, corresponding enrichment of the residual matter in gold, and also with the change in the composition of the substance filling the pores. Micropores in the mustard gold are filled with iron, antimony or thallium oxides, silver chlorides, bromides, and sulfides. The formation of mustard gold with chlorides and bromides shows that halogens played an important role in the remobilization of noble metals at the stage of hypergene transformation of the Oleninskoe deposit.

Sex-Based Differences in the Cytokine Production and Intracellular Signaling Pathways in Patients With Rheumatoid Arthritis

Objectives: This study aims to investigate lymphoproliferation, cytokine production, and intracellular signaling molecules in peripheral blood mononuclear cells (PBMCs) isolated from healthy individuals and rheumatoid arthritis (RA) patients to understand the extent of the involvement of these pathways in the pathogenesis of RA. Patients and methods: The study included 65 participants (29 males, 36 females; mean age 51.8 +/- 10.3 years; range, 37 to 71 years) who were categorized into four groups as healthy males (n=22, mean age 49.8 +/- 10.6 years; range, 39 to 65 years), male RA patients (n=7, mean age 51.8 +/- 13.9 years; range, 37 to 68 years), healthy females (n=20, mean age 53.7 +/- 8.8 years; range, 42 to 67 years), and female RA patients (n=16, mean age 52.9 +/- 10.4 years; range, 40 to 71 years). PBMCs were collected from the participants and analyzed for Concanavalin A (Con A)-induced lymphoproliferation using 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide assay, cytokine production, and phospho-signal transducer and activator of transcription 3 (p-STAT-3), phospho-extracellular- signal-regulated kinase (p-ERK), phospho-cAMP response element binding (p-CREB), and phospho-protein kinase B expressions using enzyme-linked immunosorbent assay. Short form of the Arthritis Impact Measurement Scales 2 and multidimensional health assessment questionnaire were used to measure the level of disability and the quality of life. Results: In RA patients, production of Con A-induced interleukin (IL)-2 and IL-17 was higher in both sexes while interferon-gamma levels decreased in RA females alone. Expression of p-STAT-3 in PBMCs increased in RA males while it was unaltered in RA females. p-ERK expression was not altered while p- CREB expression was enhanced in RA males and females. Protein-protein interaction analyses demonstrated that these and other key signaling molecules were dysregulated in RA patients. Conclusion: Our results suggest that sex-based differences in RA pathogenesis result from differential alterations in signaling pathways to influence the inflammatory process.
