The aim of this study was to develop a derivative of chitosan as pharmaceutical excipient used in sustained-release matrix tablets of poorly soluble drugs. A water-soluble quaternary ammonium carboxymethylchitosan was synthesized by a two-step reaction with carboxymethylchitosan (CMCTS), decylalkyl dimethyl ammonium and epichlorohydrin. The elemental analysis showed that the target product with...
Sustained release of thermal-instable and water-soluble drugs with low molecule weight is a challenge. In this study, sodium bicarbonate was encapsulated in ethyl cellulose microspheres by a novel solid-in-oil-in-oil (S/O/O) emulsification method using acetonitrile/soybean oil as new solvent pairs. Properties of the microspheres such as size, recovery rate, morphology, drug content, and drug re...

Objective: Present study compares relationship between motor performance, sustained attention and impulse control in children with Attention Deficit Hyperactivity Disorder and normal children. Materials & Methods: In this descriptive-analytic study, 21 boys with ADHD and 21 normal boys in the age range of 7- 10 years old were participated. Motor performance by using Bruininks Oseretsky Test ...
Introduction: The aim of this study is to assess the therapeutic efficacy and safety of a particular brand of IFN alpha (PDferon B®) in combination with ribavirin (RlBA) on Iranian patients with chronic hepatitis C (CHC). The addition of RIBA to the standard treatment with interferon (IFN) alpha led to an improvement in sustained virologic response (SVR) from less than 20% with IFN monother...
Dispersion coefficients for the long-range interactions of the first four excited states of He, i.e., He(2 (1, 3)S) and He(2 (1, 3)P), with the low-lying states of the alkaline earth atoms Mg, Ca, and Sr are calculated by summing over the reduced matrix elements of multipole transition operators.
The increasing burden of dengue, and the relative failure of traditional vector control programs highlight the need to develop new control methods. SIT using self-limiting genetic technology is one such promising method. A self-limiting strain of Aedes aegypti, OX513A, has already reached the stage of field evaluation. Sustained releases of OX513A Ae. aegypti males led to 80% suppression of a t...
conclusions all paddle-boarding injuries were sustained by individuals who surf waves on a paddle-board, rather than paddle on calm water. despite concerns, paddle-board related injuries only accounted for 1% of 326 injuries suffered by surfers. we suggest equipment and practice modifications that may decrease the risk for injury and challenge the anecdotal theory that paddle-boarding injuries ...
