preformulation studies on transdermal dosage forms involve liberal use of animal skin for assessing the permeation characteristics of drugs, influence of permeation enhancers, optimizing the formulation variables etc. the restricted availability of animal skin due to concerns regarding prevention of cruelty to animals has generated considerable interest in developing polymeric films for use as ...

Chitosan with excellent biodegradable and biocompatible characteristics has received attention as an oral drug delivery vehicle for controlled-release formulations. In this study an enteric-coated capsule containing theophylline-chitosan beads based on 23 factorial designs was prepared as a colon drug delivery system. The theophylline-chitosan gel beads were formulated by adding the drug-contai...

Bromeliads are used in landscaping due to the beauty of their leaves and flowers. The use plant regulators such as nitric oxide (NO) promotes stimulus germination it has been a way out enhance production reduce search for plants nature nanoencapsulation aims optimize its effect. objective this work was evaluate effect using free nanoencapsulated NO donor on D. excelsa. treatments consisted soak...

The encapsulation of soft coral Dendronephthya gigantea (SCD) in biopolymers could be attributed to the nature this extract. In present work, chitosan nanoparticles (NCS) as natural biopolymer was prepared using sodium tripolyphosphate (TPP) via ionic gelation method and then encapsulated with SCD. Firstly, GC-MS used determine components More than Forty-components SCD, constituting 89.94%, wer...

OBJECTIVE The objective of this study was to evaluate the effects of ageing time of lamb loins prior to freezing on technological characteristics and oxidation stability of coarse ground lamb loin sausage using in a model system. METHODS Lamb loins (M. longissimus lumborum, n = 25) were aged at -1.5°C for 0, 1, 2, 3, and 8 wk and then frozen for the remaining days (a total of 30 wk). The aged...
