The present study focus on synthesis of visible-light active pure, Fluoride (F) - and Silica (Si)-doped titanium dioxide (TiO2) photocatalyst. Designing the nanoparticles under sol–gel process method is adopted. Characterizations such as SEM, XRD, FTIR, DLS revealed about crystallinity, physico-catalytic properties photocatalysts. nanomaterials were tested for their photocatalytic against cryst...

Plasmid pGNB1 was isolated from bacteria residing in the activated sludge compartment of a wastewater treatment plant by using a transformation-based approach. This 60-kb plasmid confers resistance to the triphenylmethane dye crystal violet and enables its host bacterium to decolorize crystal violet. Partial sequencing of pGNB1 revealed that its backbone is very similar to that of previously se...

We compared histological and immunological techniques in the early diagnosis of Pneumocystis carinii pneumonia in bronchial lavage fluid of steroid-treated rats. The rats were sacrificed weekly and lavage fluids were: (i) examined with cresyl echt violet and Giemsa stains; (ii) examined for P. carinii antigens by indirect fluorescent-antibody, counterimmunoelectrophoresis, and double-diffusion ...

Violet electroluminescence is rare in both inorganic and organic light-emitting diodes (LEDs). Low-cost and room-temperature solution-processed lead halide perovskites with high-efficiency and color-tunable photoluminescence are promising for LEDs. Here, we report room-temperature color-pure violet LEDs based on a two-dimensional lead halide perovskite material, namely, 2-phenylethylammonium (C...

In this study, we observed the ontogenetic changes in glucose transporter 3 (GLUT3) immunoreactivity, a major neuronal GLUT, in the dentate gyrus of mouse brains at various ages: postnatal day (P) 1, 7, 14, 28, and 56. At P1, cresyl violet staining showed abundant neurons in the dentate gyrus, whereas the granule cell layer was ill-defined. At P7, the granule cell layer was observed, and cresyl...

Silver clusters with ~10 atoms form within DNA strands, and the conjugates are chemical sensors. The DNA host hybridizes with short oligonucleotides, and the cluster moieties optically respond to these analytes. Our studies focus on how the cluster adducts perturb the structure of their DNA hosts. Our sensor is comprised of an oligonucleotide with two components: a 5'-cluster domain that comple...

BACKGROUND In atopic eczema (AE), skin colonization with Staphylococcus aureus plays a possible role in the pathophysiology of the disease. METHODS Thirty-eight patients with AE were screened for their cutaneous colonization with S. aureus. The antibacterial and clinical efficacy of topical therapy with the antiseptic dye gentian violet, a potent glucocorticosteroid or a tar solution (liquor ...

A study to establish relationship between the petal colour, extraction solvent, phenolic, flavonoid, anthocyanin content and antioxidant activity in three varieties of Viola × wittrockiana (yellow, red and violet) is reported in this article. Identification and quantification of flavonoids and anthocyanins using HPLC-DAD-ESI-MS is also presented. The antioxidant activity was studied by four dif...

With a panoramic view of the scene, a single omnidirectional camera can monitor the 360-degree surround of the vehicle or monitor the interior and exterior of the vehicle at the same time. We investigate problems associated with integrating driver assistance functionalities that have been designed for rectilinear cameras with a single omnidirectional camera instead. Specifically, omnidirectiona...

I t has been known for many years tha t ul tra-violet light is bactericidal. Finsen and Dreyer (1), in 1903, were probably the first to Show tha t light with short wave-lengths is virucidal also. More recent ly (2-7) other reports have appeared dealing with the effects of ul tra-violet irradiation upon bacteria, viruses, and enzymes. For the most par t , however, single wave-lengths have not be...
