Colloidal stability of nanoparticles in biological media is an important consideration, when trying to ensure reliable data interpretation of in vitro and in vivo systems. We have developed a detailed colloidal stability ...

Norfloxacin, an antibiotic that exists in different solid forms, has very unfavorable properties in terms of solubility and stability. Binary complexes of norfloxacin, in the solid form C, and β-cyclodextrin were procured ...

Over the last years, some of the main countries in Latin America have undergone deep, sometimes unexpected political changes, without major effects on their economies. Political and institutional instability seems to be ...

The rate of evolution varies among sites within proteins. In enzymes, two rate gradients are observed: rate decreases with increasing local packing and it increases with increasing distance from catalytic residues. The ...

Islet Neogenesis Associated Protein pentadecapeptide (INGAP-PP) increases β-cell mass and function in experimental animals. A short clinical trial also yielded promising results. However, HTD4010, a new peptide derived ...

The emulsifying properties of Brea gum (BG), the exudate from Cercidium praecox, were studied in comparison to gum Arabic (GA). Droplet size distributions, rheological properties and stability of corn oil emulsion stabilized ...

Adaptation of life to low temperatures influences both protein stability and flexibility. Thus, proteins from psychrophilic organisms are excellent models to study relations between these properties. Here we focused on ...

Suitable continuity and boundedness assumptions on the function f defining the dynamics of a time-varying nonimpulsive system with inputs are known to make the system inherit stability properties from the zero-input system. ...

The freeze-thaw stability of oil-in-water emulsions prepared with unheated and heated aqueous dispersions of fresh and stored soy protein isolates was evaluated in the absence and presence of glucose or sorbitol (0.75-15.0% ...

Liquid formulations can be used in children of different ages by varying the volume of the administered dose in order to ensure an exact dosage. The aim of this work was to develop and to optimize a safe liquid atenolol ...
