Effects of permethrin at different temperatures on pyrethroid-resistant and susceptible strains of Anopheles
(1999)
The influence of temperature (16, 22, 28, 37 degrees C) on effects of permethrin was investigated for susceptible and pyrethroid-resistant strains of the mosquitoes Anopheles gambiae and An. stephensi (Diptera: Culicidae). ...
Comparison of various cosolvency models for calculating solute solubility in water-cosolvent mixtures
(1999)
Previously published cosolvency models are critically evaluated in terms of their ability to mathematically correlate solute solubility in binary solvent mixtures as a function of solvent composition. Computational results ...
The effect of moisture on the compaction properties of the binary mixture of hydroxypropylmethyl cellulose K4M/ibuprofen
(1998)
The consolidation and compaction properties of hydroxypropylmethyl cellulose K4M and ibuprofen containing various moisture contents were evaluated. The powders were compressed using a high-speed compaction simulator. The ...
The role of various surfactants and fillers in controlling the release rate of theophylline from HPMC matrices
(1999)
The effect of lactose, NaCMC and various surfactants, i.e. sodium lauryl sulfate, cetyltriammonium bromide, Arlacel 60 and Tween 80 on the release rate of theophylline from HPMC matrices was evaluated. The results showed ...
Age, acquired immunity and the risk of visceral leishmaniasis: a prospective study in Iran
(1999)
In order to investigate the phenomenon of age-related immunity to visceral leishmaniasis, a 1 year prospective survey was carried out on 5671 people in a Leishmania infantum focus in north-west Iran. The average incidence ...
Exhaled nitric oxide as a noninvasive assessment of chronic cough
(1999)
Exhaled nitric oxide (ENO) has been suggested as a marker of airway inflammation. This study aimed to evaluate the role of ENO in the investigation of chronic cough. We measured ENO in 38 adult patients reporting chronic ...
The compaction properties of mixtures of ibuprofen and hydroxypropylmethyl cellulose
(1998)
The consolidation and compaction properties of hydroxypropylmethyl cellulose K4M and ibuprofen, and their binary mixtures were evaluated. Powders were compressed using a high-speed compaction simulator at different compression ...
Effects of hydrophilic excipients and compression pressure on physical properties and release behavior of aspirin-tableted microcapsules
(1999)
Aspirin ethylcellulose microcapsules were tableted by compression with or without excipients (lactose or polyvinylpyrrolidone [PVP]). The effects of the amount of the excipients and microcapsule size on the crushing strength ...
Effect of polysorbates on atenolol release from film-coated tablets
(1999)
The effects of different concentrations of various polysorbates on the release rate of atenolol from film-coated tablets were evaluated. The release profile of atenolol showed that increasing the concentration of polysorbate ...
Solubility correlation of structurally related drugs in binary solvent mixtures
(1998)
Applicability of the well-established cosolvency equation, i.e. combined nearly ideal binary solvent/Redlich-Kister, CNIBS/R-K, model for calculating the solubility of structurally related drugs in a given cosolvent and ...
