INTRODUCTION Angiotensin-converting enzyme (ACE) inhibitors represent a significant group of drugs primarily used in the treatment of hypertension and congestive heart failure. OBJECTIVE Selected ACE inhibitors (enalapril, quinapril, fosinopril, lisinopril, cilazapril) were studied in order to establish a fast and easy estimation method of their plasma protein binding degree based on their li...

some properties of compounds in degrading bacteria are required for biodegradation of contaminants to higher performance. those strains which have a high percentage of these features are more effective at biodegradation. the present experiments were designed to measure these parameters. in this study, measurement of cell surface hydrophobic-degrading bacteria was designed which oil was separate...

As anyone who has looked at a petunia or a pansy can testify, plants generate flowers with characteristic numbers and patterns of organs. The floral organs are derived from a pool of stem cells called the floral meristem. In wild-type Arabidopsis thaliana flowers (shown at lower left) the meristem gives rise to four sepals that enclose the bud, four white petals, six pollen-bearing stamens and ...

The aim of this study was to determine the degree of adhesion and hydrophobicity of some strains of lactic acid bacteria (LAB) with proven antagonistic properties against pathogenic bacteria. Studies were performed using-LAB strains isolated from the gastrointestinal tract of calves and piglets. These strains exhibited an antibacterial activity against pathogenic strains of Clostridium perfring...

Silica monolith aerogels with different degrees of hydrophobicity by incorporating methyltrimethoxysilane (MTMS) or trimethylethoxysilane (TMES) in standard sol-gel synthesis were prepared. Excellent properties of the aerogels, obtained with the sol-gel synthesis, were preserved with supercritical drying with CO2. The degree of the hydrophobicity of the aerogels was tested by measuring the cont...

An increase of the degree of d-alanylation of teichoic acids in Lactococcus lactis resulted in a significant increase of bacterial resistance toward the cationic antimicrobials nisin and lysozyme, whereas the absence of D-alanylation led to a decreased resistance toward the same compounds. In contrast, the same variations of the D-alanylation degree did not modify bacterial cell surface charge ...

Molecular-dynamics simulations have been performed for full liquid water adsorbed onto two planar silicon surfaces, with varying hydrogen- and hydroxyl-termination (mimicking different extents of hydrophobicity hydrophophilicity). It was found that there water-density ‘ordering’ perpendicular to both surfaces – heavily dependent on the degree hydrophobicity. The position width three solvation l...
