Real-time UV imaging identifies the role of pH in insulin dissolution behavior in hydrogel-based subcutaneous tissue surrogate.

Eur. J. Pharm. Sci. 69 , 26-36, (2015)

For parenteral biopharmaceuticals, subcutaneous diffusion and, in the case of solid implants or suspensions, dissolution may govern the clinical profile of the drug product. Insight into the dissolution and diffusion processes of biopharmaceuticals after pare...

The transcription factor BcLTF1 regulates virulence and light responses in the necrotrophic plant pathogen Botrytis cinerea.

PLoS Genet. 10(1) , e1004040, (2014)

Botrytis cinerea is the causal agent of gray mold diseases in a range of dicotyledonous plant species. The fungus can reproduce asexually by forming macroconidia for dispersal and sclerotia for survival; the latter also participate in sexual reproduction by b...

The VELVET Complex in the Gray Mold Fungus Botrytis cinerea: Impact of BcLAE1 on Differentiation, Secondary Metabolism, and Virulence.

Mol. Plant Microbe Interact. 28 , 659-74, (2015)

Botrytis cinerea, the gray mold fungus, is an important plant pathogen. Field populations are characterized by variability with regard to morphology, the mode of reproduction (conidiation or sclerotia formation), the spectrum of secondary metabolites (SM), an...

A Legionella effector modulates host cytoskeletal structure by inhibiting actin polymerization.

Microbes Infect. 16(3) , 225-36, (2014)

Successful infection by the opportunistic pathogen Legionella pneumophila requires the collective activity of hundreds of virulence proteins delivered into the host cell by the Dot/Icm type IV secretion system. These virulence proteins, also called effectors ...

Spectrophotometric determination of enalapril through ternary complex formation.

Rev. Med. Chir. Soc. Med. Nat. Iasi. 116(3) , 914-9, (2012)

Enalapril is an angiotensin-converting enzyme inhibitor widely used in the treatment of hypertension and heart failure.To design and validate a simple and sensitive spectrophotometric method. This method is based on a ternary complex formation between enalapr...

The interfacial interactions of Tb-doped silica nanoparticles with surfactants and phospholipids revealed through the fluorescent response.

Colloids Surf. B Biointerfaces 92 , 327-33, (2012)

The quenching effect of dyes (phenol red and bromothymol blue) on Tb(III)-centered luminescence enables to sense the aggregation of cationic and anionic surfactants near the silica surface of Tb-doped silica nanoparticles (SN) in aqueous solutions. The Tb-cen...

Experimental correlation between the pKa value of sulfonphthaleins with the nature of the substituents groups.

Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 69(4) , 1235-45, (2008)

This work presents the results obtained from a spectrophotometry study performed on some indicators of the sulfonphtaleins like phenol red (PR), thymol blue (TB), bromothymol blue (BTB), xylenol orange (XO) and methylthymol blue (MTB). During the first stage ...

Direct colorimetric detection of copper(II) ions in sampling using diffusive gradients in thin-films.

Anal. Chim. Acta 662(1) , 44-50, (2010)

A novel binding phase was developed for use in diffusive gradients in thin-film (DGT) sampling for Cu(II) by employing methylthymol blue as a chelating and chromogenic agent. Methylthymol blue was adsorbed onto beads of Dowex 1 x 8 resin (200-400 mesh) and th...

Determination of fluoride and oxalate using the indicator reaction of Zr(IV) with methylthymol blue adsorbed on silica gel.

Anal. Chim. Acta 597(1) , 171-7, (2007)

Solid-phase spectrophotometric and visual test-methods of fluoride and oxalate determination are proposed. The methods are based on the competitive reactions of ZrOCl2 with methylthymol blue immobilized on silica gel and fluoride or oxalate in solution. Absor...

Pseudomonas spp. and Serratia liquefaciens as Predominant Spoilers in Cold Raw Milk.

J. Food Sci. 80 , M1842-9, (2015)

The storage of fresh raw milk at low temperature does not prevent proliferation of psychrotrophic bacteria that can produce heat-resistant proteolytic enzymes contributing to the reduced shelf life of dairy products. This study aimed to identify the dominant ...
