Antigen-specific activation of cytotoxic T cells can be enhanced up to three-fold more than soluble controls when using functionalized bundled carbon nanotube substrates ((b) CNTs). To overcome the denaturing effects of direct adsorption on (b) CNTs, a simple but robust method is demonstrated to stabilize the T cell stimulus on carbon nanotube substrates through non-covalent attachment of the l...

Chloropinane and chloromenthene, synthesized from pinene limonene, respectively, were compared with their non-halogenated analogs n-hexane for ability to solubilize natural products of interest such as ?-carotenoids, vanillin, rosmarinic acid. was six times more efficient than hexane ?-carotene solubilization. Chloromenthene 15 better hexane. Vanillin 20 soluble in chloropinane chloromenthene 3...

N-d-Gluco-N-methylalkanamide detergents have been synthesized. The detergents, which were produced in high yield and at low cost, compared favourably in biochemical studies with commonly used non-ionic detergents, including a chemically related n-alkyl glucoside. The ease of removal by dialysis, high solubilizing power and non-denaturing properties of this new class of detergents make them valu...

The genetic improvement of production traits can be made through marker assisted selection using a candidategene approach. Bone morphogenetic proteins (BMPs) are multifunctional growth factors that belong to thetransforming factor b (TGF-b) superfamily. This study aimed detect the polymorphism BMP-4in different goat breeds by polymerase chain reaction-single strand confirmational (PCR-SSCP) and...

the iranian thymus daenensis subsp. daenensis is rich in monoterpene phenols (especially thymol and carvacrol). this research was conducted to isolate and characterize the plant growth promoting rhizobacteria (pgprs) from rhizosphere of t. daenensis. pgprs were screened based on some physiological traits including iaa production, phosphate solubilization, and siderophore compounds production ab...

The dynamics of liposome solubilization was monitored by dynamic light scattering and optical microscopy. A newly designed Y-shape microchannel connected to a room was incorporated into a microchip and the reaction processes of the liposome suspension and surfactant solution were observed in the room after mixing the two fluids and stopping the flow. By using this microchip, we succeeded in r...

The remediation of metal-contaminated sediment was studied using the bioleaching process with a mixed culture of sulfur-oxidizing bacteria. The effects of substrate concentration (elemental sulfur) on sediment acidification, sulfur oxidation and metal solubilization from contaminated sediment during the bioleaching process were investigated with free-cell suspensions. Sulfur concentration great...

In this study, among a collection of Ni-resistant bacterial strains isolated from the rhizosphere of Alyssum serpyllifolium and Phleum phleoides grown on serpentine soil, five plant growth-promoting bacteria (PGPB) were selected based on their ability to utilize 1-aminocyclopropane-1-carboxylate (ACC) as the sole N source and promote seedling growth. All of the strains tested positive for indol...

G protein-coupled receptors (GPCRs) are the largest class of molecules involved in signal transduction across cell membranes and are major drug targets. Since GPCRs are integral membrane proteins, their structure and function are modulated by membrane lipids. In particular, membrane cholesterol is an important lipid in the context of GPCR function. Solubilization of integral membrane proteins i...
