OBJECTIVE The present paper describes an in silico solubility behavior of drug and lipids, an essential screening study in preparation of solid lipid nanoparticles (SLN). MATERIALS AND METHODS Ciprofloxacin HCl was selected as a model drug along with 11 lipids and 5 organic solvents. In silico miscibility study of drug/lipid/solvent was performed using Hansen solubility parameter approach cal...

In this paper, we present PyKrev, a Python library for the analysis of complex mixture Fourier transform mass spectrometry (FT-MS) data. PyKrev is comprehensive suite tools and visualization FT-MS data after formula assignment has been performed. These comprise manipulation calculation chemical properties, intersection between multiple lists formulas, diversity, compound classes to multivariate...

Coalbed methane (CBM) plays an important role in coal mining safety and natural gas production. In this work, The CBM potential of B2 seam in Parvadeh IV coal deposit, in central Iran, was evaluated using a combination of local regression and geostatistical methods. As there were 30 sparse methane sampling points in the Parvadeh IV coal deposit, no valid variogram was achieved for the methane c...

Most studies of active aeolian processes on Mars have focused on dust [1], i.e., particles -1 [tm in diameter that are transported in suspension by wind. The presence of sand dunes on Mars [2-8] indicates that larger grains ( >60 _tm, transported primarily in saltation) are also present. Although indirect evidence suggests that some dunes may be active [9], definitive evidence is lacking. Nonet...

In this paper, the main problem and countermeasure of fruit production quality and safety were studied in Yanshan Mountain. The subjective factor was fruit farmer quality and safety consciousness faint, and the objective factors were: severe orchard environmental pollution, faint fruit postharvest handling, lag in process technology, fruit quality determination and market inspection system is n...

Coffee is one of mankind's most popular beverages obtained from green coffee beans by roasting. Much effort has been expended towards the chemical characterisation of the components of the roasted coffee bean, frequently termed melanoidines, which are dominated byproducts formed from its most relevant secondary metabolites - chlorogenic acids. However, impeded by a lack of suitable authentic re...

In the present study, a new copolymer containing pyrazole substituted 1,3-diphenyl-1H-pyrazol-5-yl methacrylate (DPMA) and styrene (St) units, [poly(DPMA-co-St)], was synthesized. Thermal degradation kinetics of system investigated in detail with thermogravimetric analysis (TGA) technique. An increase thermal stability from 252.02 °C to 274.89 observed depending on change heating rate (5 °C/min...

Quercetin is a bioflavonoid compound with low water solubility in both foods and the gastrointestinal tract, which limits exploitation of its health-promoting properties. This study aims to formulate solid dispersions (SDs) quercetin hydrophilic polyethylene glycol PEG matrices, using melt-mixing method, improve dissolution antioxidant activity quercetin. Initially, total Gibbs free energy for ...
