Development of novel sustained release matrix pellets of betahistine dihydrochloride: effect of lipophilic surfactants and co-surfactants.
Pharm. Dev. Technol. 17(5) , 583-93, (2012) Sustained release matrix pellets of the freely water soluble drug, betahistine dihydrochloride (BH), were prepared using freeze pelletization technique. Different waxes and lipids (cetyl alcohol, beeswax, glyceryl tripalmitate (GTP) and glyceryl tristearate) ... |

A new ovitrap made of slow release natural materials containing pyriproxyfen for Aedes aegypti (Diptera:Culicidae) control.
J. Med. Entomol. 50(4) , 916-9, (2013) ABSTRACT This initial study is aimed to measure the performance of incorporating pyriproxyfen in natural materials with low environmental impact to obtain slow release formulations that can be used as larvicidal or autocidal ovitraps avoiding hatched Aedes ae... |

Authentication of beeswax (Apis mellifera) by high-temperature gas chromatography and chemometric analysis.
Food Chem. 136(2) , 961-8, (2013) Chemical characterization and authentication of beeswax of Apis mellifera was performed by high temperature capillary gas chromatography coupled to electron impact mass spectrometry or to flame ionisation detection and chemometric analysis. Many major compone... |

Effect of solid content and composition of hydroxypropyl methylcellulose-lipid edible coatings on physico-chemical and nutritional quality of 'Oronules' mandarins.
J. Sci. Food Agric. 92(4) , 794-802, (2012) Citrus fruit represent an important source of vitamin C, as well as other bioactive compounds. Edible coatings have the potential to extend shelf life of citrus by providing a semi-permeable barrier to water and gases, which depends on coating composition, so... |

The composition of some Roman medicines: evidence for Pliny's Punic wax?
Anal. Bioanal. Chem 401(6) , 1749-59, (2011) Residues from medicine containers in the collections of the British Museum have been investigated as part of a wider programme of scientific work on Roman surgical instruments. The cylindrical bronze containers are often described as instrument cases, but som... |

Economics of comb wax salvage by the red dwarf honeybee, Apis florea.
J. Comp. Physiol. B, Biochem. Syst. Environ. Physiol. 181(3) , 353-9, (2011) Colonies of Apis florea, which only abscond a short distance, usually return to salvage old nest wax; but, those colonies, and all other honeybee species which go considerably further, do not. Wax salvage would clearly be counter-productive unless the energy ... |

Spectral analysis of pharmaceutical formulations prepared according to ancient recipes in comparison with old museum remains.
Anal. Bioanal. Chem 401(6) , 1839-46, (2011) A study of the composition of the remains of ancient ointments from museums was undertaken to enable understanding of the preparation techniques. Comparison of ancient recipes from different historical periods and spectroscopic characteristics of inorganic an... |

Hexagonal comb cells of honeybees are not produced via a liquid equilibrium process.
Naturwissenschaften 100(1) , 45-9, (2013) The nests of European honeybees (Apis mellifera) are organised into wax combs that contain many cells with a hexagonal structure. Many previous studies on comb-building behaviour have been made in order to understand how bees produce this geometrical structur... |

Photostabilization of sunscreen oil through preparation of a free-flowing powder.
J. Microencapsul. 28(3) , 159-65, (2011) Octyl-p-methoxycinnamate (OMC) is a sun-blocking agent that absorbs ultraviolet (UV) radiation in UVB range. However, when exposed to sunlight, OMC is converted into a less UV-absorbent form, which reduces its effectiveness. The aim of this study was to stabi... |

Modulation of drug release from nanocarriers loaded with a poorly water soluble drug (flurbiprofen) comprising natural waxes.
Pharmazie 67(8) , 701-5, (2012) In this study, flurbiprofen (FLB) Solid Lipid Nanoparticles (SLN) composed from a mixture of beeswax and carnauba wax, Tween 80 and egg lecithin as emulsifiers have been prepared. FLB was incorporated as model lipophilic drug to assess the influence of matrix... |
