Corn stalk can be used as an alternative non-wood raw material to produce cellulosic dissolving grade pulp. In this work, the potential of corn stalk in the production of dissolving pulp (alpha-cellulose) was investigated. It was collect ed from a corn stalk farm of Kermanshah, Iran. The sequences of experimental work were: water and acid prehydrolysis at 160˚C for 30min, followed by Kraft pulp...

Cu electropolishing was studied using a rotating disc electrode in a variety of phosphoric acid-based electrolytes, including several with ethanol and other species added as diluents. Diluents allow a wider range of water concentrations and electrolyte viscosities to be accessed and also reduce the removal rate during Cu electropolishing, simplifying possible application to damascene processing...

PURPOSE To enhance the immunogenicity of the model subunit vaccine, ovalbumin (OVA) was combined with platycodin (PD), a saponin adjuvant. To reduce the toxicity of PD, OVA, and adjuvant were loaded together into liposomes before being incorporated into a dissolving microneedle array. METHODS OVA- and PD-loaded liposomes (OVA-PD-Lipos) were prepared using the film dispersion method. Their upt...

Fast dissolving drug delivery is the new approach to administer drugs; mouth dissolving film is one of them. The object of the present research work was to formulate a mouth dissolving film of Zolpidem tartrate from polymers Hydroxypropyl cellulose (EF-P) with a combination of Hydroxypropyl methyl cellulose K-15 by solvent casting method for enhancing the drug release rate and absorption to inc...

The objective of this paper was to review the information about mouth dissolvi improve patient’s compliance have always attracted scientists towards the development of fancy oral drug delivery systems. Among them, mouth dissolving drug delivery systems (MDDDS) have acquired an important position in the market b and contributing to extension of patent life. MDDDS have the unique property of rapi...

The clinical impact of biotechnology has been constrained by the limitations of traditional hypodermic injection of biopharmaceuticals. Microneedle patches have been proposed as a minimally invasive alternative. In this study, the translation of a dissolving microneedle patch designed for simple, painless self-administration of biopharmacetucials that generates no sharp biohazardous waste is as...

INTRODUCTION The purpose of this in vitro study was to evaluate three common gutta-percha solvents' effectiveness in dissolving three different types of root canal sealers. MATERIALS AND METHODS The solubility of three different root canal sealers (AH Plus, Apexit Plus and Endoflas FS) was assessed in xylene, refined orange oil, tetrachloroethylene and distilled water (control). One-hundred t...

This study was concerned with the investigation of acute pharmacological responses (pharmacodynamics) including analgesic and anti-inflammatory effects of ketorolac tromethamine fast dissolving tablets prepared by direct compression method using 3% croscarmellose sodium as a superdisintegrant by applying tail flick test and carragenan induced rat paw edema test respectively. Also, the work aime...

PURPOSE Solvents may be used to remove the filling materials. The purpose of this in vitro study was to evaluate and compare the efficacy of formulated orange oil, orange oil and formulated eucalyptol in dissolving F3 ProTaper Universal Gutta-percha points. MATERIAL AND METHODS 200 samples were used and divided into four groups, further divided in fifty samples for each solvent. The samples w...
