The previous discoveries of butyl fenbufen amide analogs with antitumor effects were further examined. The amide analogs with 1, 3, 4 and 8 carbons chains were prepared in 70-80% yield. Fenbufen had no cytotoxic effects at concentrations ranging from 10 to 100 μM. Methyl fenbufen amide had significant cytotoxic effects at a concentration of 100 μM. As the length of the alkyl amide side chain in...

The intrinsic charge carrier transporting properties of two isomeric linear- and bent-shaped 7-ring benzo-fused thieno[3,2-b] thiophenes and their octyl-substituted analogues were newly investigated using flash-photolysis (FP-) and field-induced (FI-) time-resolved microwave conductivity (TRMC) techniques. FP-TRMC study in the solid state revealed that octyl-substitution potentially improved th...

conclusions the results of the present study indicate the protective effects of melissa officinalis on some sperm parameters and spermatogenesis quality in rats exposed to lead. background some medicinal plants with their antioxidant properties have protective effects on sperm parameters and neutralize the harmful effects of lead exposure. objectives the present study aimed to determine the eff...

Herein, silicon quantum dot light-emitting diodes (SiQD LEDs) are investigated to explore the interplay between their electroluminescence (EL) blue shift and SiQD ligand length on surface. The is essential for LED fabrication ensure colloidal stability, but it also hinders efficient charge transport inside LED. Consequently, SiQDs functionalized via organolithium reagents with hexyl, octyl, dod...

Lactiplantibacillus plantarum strain UNQLp 11 is a lactic acid bacterium with the potential to carry out malolactic fermentation (MLF) in red wines. Recently, complete genome of was sequenced and this possesses four loci enzyme ?-glucosidase. In order demonstrate that these glucosidase enzymes could be functional under harsh wine conditions, we evaluated hydrolysis p-nitrophenyl-?-D-glucopyrano...

Surface light scattering (SLS) by capillary waves was used to investigate the adsorption behavior of non-ionic sugar surfactants at the air/liquid interface. SLS by the subphase (water) followed predictions from hydrodynamic theory. The viscoelastic properties (surface elasticity and surface viscosity) of monolayers formed by octyl beta-glucoside, octyl alpha-glucoside, and 2-ethylhexyl alpha-g...

The nucleating role of cellular membrane components, such as lipid moieties on amyloid beta (A?1–40) fibrillation, has been reported in recent years. influence conjugates fabricated from anchors (cholesterol, diacylglycerol) and hydrophilic polymers A?1–40 fibrillation is here, aiming to understand the impact cloud point temperature (Tcp) its hydrophobic tails fibrillation. Novel lipid-polymer ...

Abstract: This paper presents a highly sensitive fiber-optic oxygen sensor. The sensor was fabricated using palladium (II) meso-tetrakis (pentafluorophenyl) porphyrin (PdTFPP) and porous silica nanoparticles embedded in a tetraethylorthosilane (TEOS)/n-octyl-triethoxysilane (Octyl-triEOS) composite xerogel present as a coating on the end of the fiber. Sensitivity is quantified in terms of the r...

A method for the recovery and fractionation of whey proteins from a whey protein concentrate (80%, w/w) by hydrophobic interaction chromatography is proposed. Standard proteins and WPC 80 dissolved in phosphate buffer with ammonium sulfate 1 M were loaded in a HiPrep Octyl Sepharose FF column coupled to a fast protein liquid chromatography (FPLC) system and eluted by decreasing the ionic streng...
