Manganese (Mn(2+)) has limited permeability through the blood-brain barrier (BBB). Opening the BBB such that a sufficient amount of Mn(2+) enters the extracellular space is a critical step for dynamic manganese-enhanced magnetic resonance imaging (ME-MRI) experiments. The traditional BBB opening method uses intracarotid hyperosmolar stress which results in suboptimal BBB opening, and practicall...

PURPOSE Direct measurement of the transmission of light through the human lens is not possible in vivo unless invasive techniques are used. In the current study, a reliable in vivo estimate of the transmission of blue light through the lens was assessed by comparing an indirect and noninvasive method based on autofluorescence measurements with a direct method. METHODS Total transmission of bl...

II Zw 71 (UGC 9562) was classified as a " probable " polar-ring galaxy in the Polar-Ring Catalog ((Whitmore et al. 1990)), based upon its optical appearance. We present 21 cm and optical observations of this galaxy and its companion, the blue star-forming dwarf II Zw 70. Our 21 cm observations show that 5 × 10 8 solar masses of H I is present in a polar ring orbiting II Zw 71, and show a spatia...

background and objectives: synthetic dyes are recalcitrant to degradation and toxic to different organisms. decolorization of textile wastewaters is one of the major concerns since last decades. physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. biological treatments can be more convenient. in the present study, an attempt has been made for d...

The reaction of hydrogen peroxide and  pheny -9-acridinecarboxylate in the presence of rhodamin B as a fluorophore leads to the emission of either bright blue light  or bright red light, depending on the structure of fluorescer and reaction conditions. The light emitter responsible for the Chemi Luminescence (CL) reaction is acridone and that the blue light produced with out the fluorescers...

Sequences 5' of the human blue visual pigment gene have been assayed in transgenic mice for their ability to direct cell-type-specific expression of linked beta-galactosidase (lacZ) and placental alkaline phosphatase (P ALP1) reporters. Constructs containing either 5.4 kilobases (kb) or 0.47 kb of 5' flanking DNA direct expression exclusively to the retina. Within the retina, transgene expressi...

Hydrogen peroxide is an important mild oxidant which is widely used in various applications including remediation of waste waters and drinking water resources. The safe level of H2O2 residue has to be controlled through accurate and precise measurement methods. A facile spectrophotometric method for the determination of hydrogen peroxide is based on the reaction of iodine ...

The full-length genome sequence of a human enterovirus 71 (EV71) strain (EV71/CZTN01/CHN/2017) was isolated from a throat swab from a child in Changzhou, China, in 2017. According to the phylogenetic analyses, the full-genome sequence in this study belongs to sub-subgenotype C4a.
