P-solubilizing microorganisms are a promising alternative for a sustainable use of P against a backdrop of depletion of high-grade rock phosphates (RPs). Nevertheless, toxic elements present in RPs, such as fluorine, can negatively affect microbial solubilization. Thus, this study aimed at selecting Aspergillus niger mutants efficient at P solubilization in the presence of fluoride (F-). The mu...

Such dosages’ requirements go along with the necessity to evaluate other formulation technologies for enhan...

We have observed large pores in the membrane of giant vesicles in an aqueous medium. The lifetime of the pores can reach 2 min and their size (a few micrometers) enables their visualization by fluorescence microscopy. These pores are obtained thanks to a destabilization of the membrane due to the synergistic action of a cone-shaped and nitrobenzodiazole (NBD) labeled phospholipid illuminated in...

Bile salts are essential for phospholipid secretion into the bile. To study the relevance of the structure of phospholipids for their interaction with bile salts, we used spin-labeled or fluorescent phospholipid analogues of different head groups and acyl chain length. Those analogues form micelles in aqueous suspension. Their solubilization by bile salts resulting in the formation of mixed mic...

BACKGROUND The importance of membrane compartmentalization into specific membrane microdomains has been shown in many biological processes such as immunoreceptor signaling, membrane trafficking, pathogen infection, and tumor progression. Microdomains like lipid rafts, caveolae and tetraspanin enriched microdomains are relatively resistant to solubilization by some detergents. Large detergent-re...

the drb3 gene is a highly polymorphic major histocompatibility complex (mhc) class ii gene and plays an important role in variability of immune responsiveness and disease resistance. in the present study, the mhc class ii drb3 gene in water buffalo (bubalus bubalis) populations from northwest regions of iran was investigated through pcr-sscp. genomic dna was extracted from whole blood samples c...

some biochemical characteristics of common carp (cyprinus carpio) and silver carp (hypophtalmichthys moltrix) surimi prepared by a conventional washing method and protein isolated using alkaline-acid-aided processes were investigated. solubility of protein in silver carp and common carp were found to be highest by using the conventional washing method. decreases in myoglobin and lipid contents ...

Solubility enhancement of antimicrobial drug enrofloxacin has been studied using a series of co-solvents and surfactants. Aqueous solubility of enrofloxacin could be increased up to 26 times. Co-solvents alone produced only small increase in solubility. However, the combined effect of co-solvents and buffer was synergistic and a large increase in solubility could be attained. Ionic surfactants ...
