This work investigated for the first time role of adsorption in photocatalytic degradation methylene blue and Orange II dyes presence 3-aminopropyltriethoxysilane (APTES)-modified TiO2 nanomaterials. It has been demonstrated that decrease a detrimental effect on activity. APTES/TiO2 photocatalysts were successfully prepared by solvothermal modification pressure autoclave, followed heat treatmen...

An efficient and economic approach is proposed for the fast and direct recovery of silica materials from photonic waste powder. Unlike the conventional alkaline fusion method for the extraction of silica from waste materials, this method possesses advantages of a rapid and low-energy-consumed process with total recovery yield. The obtained mesoporous silica material, denoted as MCM-41(DU)-F, wa...

ubiquicidin (ubi) [29-41] is a synthetic cationic antimicrobial peptide that preferentially binds to bacterial cell membrane at the site of infection. we aimed to assess diagnostic value of 99mtc-ubi [29-41] as a radiopharmaceutical in differentiation of bacterial infection from sterile inflammation in suspected orthopedic implants. nine patients suspected for orthopedic implant infection, all ...

Methylene blue is a toxic dye that extensively used as colorant in textile industries. Industrial effluent containing methylene blue, when drained into water bodies without proper treatment, poses serious threat to aquatic and human lives. In order protect the biocycle, various methods have been established detect remove hazardous dyes from aqueous systems. Electrochemical are preferred, owing ...

Olive (Sebastes serranoides), black (Sebastes melanops), and blue rockfish (Sebastes mystinus) are all common inhabitants of nearshore ecosystems on the West coast of North America and important components of the recreational fishery off California. Acoustic monitoring studies indicate that olive rockfish are highly residential and that black rockfish are capable of long migrations and have les...

A novel molecular thermometer with ratiometric fluorescence readout was designed and synthesized. Within a sensing temperature range of 33 to 41 °C, the fluorescence color of the nanothermometer changes from blue to green. The ratiometric change magnitude is about 8.7-fold, rendering the visual differentiation of color by the naked eyes feasible.

A 41-year-old woman with a complex congenital nevus that possessed features of both a blue nevus and a nevus of Ota is described. She was found to have melanotic hyperpigmentation of the underlying subcutaneous tissue and dura mater. Two separate melanomas developed in the tissues underlying her nevus (one in the subcutaneous tissue and another intracranially, arising from the dura).

Trypanosoma lewisi bloodstream and culture forms were agglutinated differentially with low concentrations of the cationic compounds: ruthenium red, ruthenium violet, Alcian blue chloride, 1-hexadecylpyridinium chloride, lanthanum chloride, and cationized ferritin. The bloodstream form trypanosomes gave the highest agglutination levels with each of the compounds tested. Ruthenium red was the mos...

cationic copolymer gels of acrylamide and [(methacrylamido) propyl] trimethyl ammonium chloride (maptac) were synthesized by free radical aqueous solution polymerization. the taguchi method, a robust experimental design, was employed for the optimization of the synthesis based on the equilibrium swelling capacity of the hydrogels. based on taguchi method a standard l16 orthogonal array with fiv...

In this article, we introduce and apply our de novo protein design framework, which observes true backbone flexibility, to the redesign of human beta-defensin-2, a 41-residue cationic antimicrobial peptide of the innate immune system. The flexible design templates are generated using molecular dynamics simulations with both Generalized Born implicit solvation and explicit water molecules. These...
