Serine protease inhibitors (soybean trypsin inhibitor [STI] and Bowman-Birk protease inhibitor [BBI]) found in soybeans have been shown to inhibit melanosome phagocytosis by keratinocytes via protease-activated receptor 2 (PAR-2). Pre-clinical studies have confirmed the skin lightening potential of these molecules. In this study, we investigated the efficacy of a novel soy moisturizer containin...

We report a simple and efficient colorimetric method to screen large numbers of bacterial strains for UV- and X-radiation sensitivity. We used reference radiation-sensitive and control strains of Escherichia coli K-12 to compare our colorimetric method to a standard clonogenic plating method. Our colorimetric method was as accurate as the standard method and was superior in terms of savings in ...

The formation of multi-species feeding flocks (MSFFs) through visual recruitment is considered an important strategy for obtaining food in seabirds and its functionality has been ascribed to enhanced foraging efficiency. Its use has been demonstrated in much of the world's oceans and includes numerous species. However, there is scant information on the temporal stability of the composition and ...

We report the enhancement of the colorimetric response of horseradish peroxidase (HRP) and alkaline phosphatase (AP) in bioassays by thermally evaporated silver, gold, copper and nickel thin films. In this regard, a model bioassay based on biotin-avidin interactions was employed. Biotin groups and enzymes were introduced to all surfaces using a biotinylated linker molecule and avidin, respectiv...

The aim of this study is to evaluate the concordance between the empirical choice of interdental brushes of different diameters compared to the gold standard, the IAP CURAPROX(©) calibrating colorimetric probe. It is carried out with the aim of facilitating the consensus development of best practices. All the subjects' interproximal spaces were evaluated using the reference technique (colorimet...

The definition of usability has evolved over time. Some of the proposed definitions have been general, and apply to all types of interactive systems. Others were tremendously influenced by the experience of those who proposed the definitions and the domain in which they practiced usability. The definitions, in general, seem to agree that the targeted users, the complexity of the task, the type ...

The colorimetric error depends on the spectrophotometric inaccuracy. In this paper, a ‎new method is introduced for determining the relationship between spectrophotometric ‎error and colorimetric inaccuracy. The error propagation in colorimetric parameter ‎calculation is evaluated using a linear relation between variance of reflectance spectra ‎and CIE tristimulus values. This linear formula ca...

dust accumulation capacity of ficus carica l. and psidium guajava l. was investigated from eight different sites of multan, pakistan.  leaves of both plants were used for analyzing biometric (leaf area, fresh and dry weights) and biochemical attributes (chlorophyll contents, carotenoids and ascorbic acid).  maximum dust accumulation was occurred in the plants growing near road sites, while, min...
