T HE superlative for logical dental reasoning during the first half of the present century might be awarded to Dr. John Hunter for his views on the theory of dental foci of infections, and to Dr. Gysi a close second for his studies of the geometric movements of the mandible. However, it is not the intention of this paper to dwell on the work of either of these men, but to discuss in part a prac...
The objective of this study was to develop a novel bacterially-triggered micro-particular system of de-esterified tragacanth (DET) in combination with Eudragit S-100 coated capsules for colon drug delivery of 5-fluorouracil (5-FU) using microemulsion method. The loading study was conducted at different drug-to-polymer ratios and cross-linker concentrations. The maximum loading efficiency was ac...

The relationship between plant species and environmental factors has always been a central issue in plant ecology. With rising power of statistical techniques, geo-statistics and geographic information systems (GIS), the development of predictive habitat distribution models of organisms has rapidly increased in ecology. This study aimed to evaluate the ability of Logistic Regression Tree model ...
The relationship between plant species and climatic factors has always been an important subject in plant ecology and the use of multivariate statistical methods might be effective in detecting the relationship between climatic factors and the distribution of plant species. In the present study, climatic characteristics of Astragalus gossypinus Fisher producing tragacanth stretched in a relativ...

In recent years worldwide interest has grown towards the development of mucoadhesive drug delivery systems. These systems are capable of adhering to body's mucosal surfaces for an extended period of time, releasing their drug content in a retarded manner. The use of biopolymers, and in particular phytopolymers, could provide a natural basis for the development of such systems. The aim of this s...
