The Raman and infrared spectra of three selectively monodeuterated species of 1-bromopentane (1-bromopentane-1-d1, -2-d1 and -3-d1) have been studied to examine the correlation between the isolated CD stretching and CHD rocking vibrations and the associated local conformation of the alkyl chai...

Studies in the preparation of aromatic ethers have proven to be quite attractive because of extensive use of these compounds in the dyestuff, perfume flavor, agriculture and pharmaceutical industries. The novelties of phase transfer catalysed alkylation of 2′-hydroxy acetophenone with 1-bromope...

Infrared and Raman spectra were obtained for 1,3-dichlorobutane and 1,3-dibromobutane. Five CBr stretch bands were observed for dibromobutane, but only three CCl stretch bands were observed for dichlorobutane. Normal coordinate calculations were made for several conformers of both compounds,...

A toxicologic and dermatologic review of hydroxycitronellol when used as a fragrance ingredient is presented.

In areas where helminths infections are common, autoimmune diseases are rare. Treatment with helminths and ova from helminths, improved clinical findings of inflammatory bowel disease, multiple-sclerosis and rheumatoid-arthritis. The immunomodulatory functions of some helminths were attributed t...

Composite resins (CRs) are widely used as dental restorative materials for caries treatment. They cause problems of secondary caries since Streptococcus mutans stays in the dental plaque, which the surface exists and produces acidic compounds during metabolism. The dental plaque depositions are ...

Two novel zwitterionic phosphorylcholine polymers (MTP1 and MTP2) with aggregation-induced emission (AIE) feature were prepared through reversible addition fragmentation chain transfer polymerization between an AIE monomer with vinyl end group and a zwitterionic phosphorylcholine monomer. The sy...

Despite the tremendous acceptance of additively manufactured (AM) Titanium alloys (Ti6Al4V) in the field of biomedical engineering, the high surface roughness due to partially-melted particles (fabricated in selective laser melting (SLM) process), limits their uses as hip implants. The objective...

A novel layer by layer (LbL) assembled structure with phosphorylcholine groups was fabricated to improve the hemocompatibility of paclitaxel/chitosan (PTX/CS) nanofibers (NF) coatings The random copolymers with phosphorylcholine groups poly (2‑methacryloyloxy-ethylphosphorylcholine‑co‑methacryli...

With the purpose of reducing side effects in anticancer therapy, the micelles of a novel reduction-activated copolymer with biomimicking phosphorylcholine, poly(ε-caprolactone)-ss-b-poly(2-methacryloyloxyethyl phosphorylcholine) (PCL-ss-PMPC) are developed. The well-suitable nanosize of micelle...

Zwitterionic polymer nanocarriers have attracted much attention in recent years due to their desirable biocompatibility and anti-fouling properties. However, the super-hydrophilic and neutral charge of zwitterionic polymer results in weak interactions with negatively charged cell membranes, whic...

ObjectivePhosphorylcholine (PC) is a structural component of Streptococcus pneumoniae (Spn) and nontypeable Haemophilus influenzae (NTHi), and is known to be associated with adherence through the platelet activating factor receptor (PAF-R). Furthermore, high PC expression is considered to be inv...

Tuftsin-PhosphorylCholine (TPC) is a novel bi-specific molecule which links tuftsin and phosphorylcholine. TPC has shown immunomodulatory activities in experimental mouse models of autoimmune diseases. We studied herein the effects of TPC ex vivo on both peripheral blood mononuclear cells (PBMCs...

5-Methoxy-1-[4-(trifluoromethyl)-phenyl]-1-pentanone-O-(2-aminoethyl)oxime (fluvoxamine), a potent clinically used antidepressant, was labelled with carbon-11 (t12 = 20.4 min) as a potential radioligand for the non-invasive assessment of serotonin uptake sites in the human brain with positron em...

Two novel N-acyl amidated bile acids, N-methyltaurine conjugated cholic acid and N-methyltaurine conjugated deoxycholic acid, were found to be major biliary bile acids in two species of angelfish the regal (Pygoplites diacanthus) and the blue-girdled (Pomacanthus navarchus) angelfish. The identi...

Bioremediation of organic pollutants has been identified as an economically efficient and environmentally friendly method. Here, a pot experiment was conducted to evaluate the bioremediation efficiency of dibutyl phthalate (DBP) by Gordonia phthalatica sp. nov. QH-11 in agricultural soils, along...

Alkyl phosphates are experiencing an ever increasing use due to the current arising of new applications. This implies their increasing presence in the environment so their stability and reactivity under high-energy photons, which are still unknown, need to be clarified.In this study, a mass spec...

Interaction between blue film of polyaniline base with dibutyl phosphonate yields green polyaniline film. This resembles the classical protonation of polyaniline base with acids but, in the contrast, there is no proton available in prevailing phosphonate tautomeric form. The character of interac...

Organocatalyzed ring-opening polymerization (ROP) of cyclic esters was developed into a stage that demanding translation of the academic success into commercially viable production. An industrial relevant development of the organocatalysis in ROPs required bulk polymerizations at high temperatur...

The phase behaviors of dihydrogenated tallowalkyl dimethyl ammonium chloride (DHTDMAC), water and different hydrocarbons were studied. Addition of different hydrocarbons to DHTDMAC and water system formed rich aggregates, including two liquid crystal aggregates and water in oil microemulsion. Th...
