Extracts of human colonic adenocarcinomata were made with perchloric acid and shown to contain antigens which were not present in pooled samples of normal colonic mucosa or in healthy colonic mucosa from patients providing the tumours. Antisera prepared against the tumour extracts gave two precipitin lines on immunodiffusion, and antiserum prepared in Montreal according to the methods devised b...

We describe the measurement of carnitine and short-chain and long-chain acylcarnitines in perchloric acid extracts of liver and muscle. [1-14C]Acetyl-CoA is used, and labeled acetylcarnitine is measured with a sensitivity of less than 1 to 50 nmol of L-carnitine per 50-microliter sample. Samples frozen at -20 degrees C lost no carnitine during several months. Analytical recovery of carnitine (5...

Objective: Many methods can be found in literature for the synthesis a Oxazines and Thiazines. Few are reported one-pot multi component cyclo-condensation of an alkayane urea / Thiourea Aldehyde to 2- amino-4H-1, 3-Oxazines or Different catalysts like Trifluoro-acetic acid, glacial acetic acid under reflux condition Mandal Co-workers have utilized perchloric (HClO4) supported on silica gel as c...

Liquid-Liquid extraction of iron (III) was carried out with 5.0X10-2 M of Tri iso-octylamine in benzene from hydrochloric, sulphuric, nitric and perchloric acid. After extraction from the organic phase, iron was stripped with 1M H2SO4 and was determined spectrophotometrically at 480nm as thiocyanate complex. The extraction was quantitative only in the presence of hydrochloric acid solution and ...

TiO2-Pd/Pt hollow nanosphere (HNS) are prepared via NaCl templates in a one-pot approach.

Low-cost, stabilized and ultrasensitive three-dimensional (3D) hierarchical surface-enhanced Raman scattering substrates ("sunflower-like" nanoarrays decorated with Ag nanoparticles, denoted as SLNAs-Ag) have been obtained by fabricating binary colloidal crystals and then decorating with Ag nanoparticles. In order to provide a larger density of hot spots within the laser-illumination area, the ...

Two newly discovered properties of tau protein are reported; it is soluble in 2.5% perchloric acid and insoluble in 25% glycerol. These properties were exploited in the development of improved methods for the purification of tau. Treatment with perchloric acid did not alter the electrophoretic behavior of tau, and the products of the new isolation method were fully competent in the promotion of...

Spin–orbit interactions of light are ubiquitous in multiple branches nanophotonics, including optical wave localization. In that framework, it is widely accepted circularly polarized beams lead to spin-dependent apparent shifts dipolar targets, commonly referred as mirages. contrast, these mirages vanish when the illumination comes from a spinless beam such linearly wave. Here we show localizat...

The Fano resonance demonstrates excellent performance due to its narrow asymmetrical spectral line shape, and sensitivity structure material parameter changes. Compared conventional resonances, the generated by magnetic dipole is more advantageous because of high absorption low loss. In this study, we propose an Au nanosphere dimer–dielectric–gold film sandwiched that supports mode. And can be ...

objective(s) several antigens, adjuvants and delivery systems have been evaluated for induction of protective immune responses against leishmaniasis, but most of them have been inefficient. in this study, plga nanospheres as antigen delivery system cpg-odn as an immunoadjuvant for increasing the immune responses against autoclaved leishmania major (alm) were prepared and characterized. material...
