Ayurveda is one of the oldest systems of medicine, practiced in Indian sub continent. We are working to calibrate classical parameters of good manufacturing practices of Ayurvedic bhasma on parameters and language of contemporary science. Bhasma in accordance of classical expectation are Swarna bhasma, Makshika bhasma, Abhrak bhasma, Tamra bhasma and Louha bhasma. X-ray diffraction, TEM and particle size analysis revealed that these bhasma are in nanometer dimension. These bhasma may be considered as nanomedicine and are free from toxicity in therapeutic doses.
OBJECTIVES: To investigate transdermal absorption enhancement of gel containing elastic niosomes loaded with gallic acid in the semipurified fraction isolated from Terminalia chebula Retz. (Combretaceae) galls. MATERIALS AND METHODS: Nonelastic and elastic niosomes loaded with gallic acid in pure form or in the semipurified fraction were developed. Rat skin permeation by vertical Franz diffusion cells of gallic acid from various gel formulations containing elastic niosomes loaded with gallic acid or the semipurified fraction was performed.
The Ergh-al-Nassa pill (Hab) is a traditional combination suggested as one of the most effective preparations useful for treatment of sciatica. Although traditional preparations can be applied as new therapeutic drugs for investigations and clinical trials, they need to be reformulated to achieve pharmacopoeial standards for modern medicine. In this research, based on seven traditional Persian pharmacopeias for Ergh-al-NassaHab, nine different molded tablets were reformulated. Each formulation comprised the same amount of colchicum, ginger, aloe and yellow myrobalan fruit.

CONTEXT: Individuals with exceptional longevity have a lower incidence and/or significant delay in the onset of age-related disease, and their family members may inherit biological factors that modulate aging processes and disease susceptibility. OBJECTIVE: To identify specific biological and genetic factors that are associated with or reliably define a human longevity phenotype.
BACKGROUND: Asian Indian women have a higher rate of coronary artery disease (CAD) than do other ethnic groups, despite similar conventional risk factors and lipid profiles. Smaller high-density lipoprotein cholesterol (HDL-C) particle size is associated with reduced cardiac protection or even an increased risk of CAD. Exceptional longevity correlates better with larger HDL-C particle sizes.
We developed a novel method to prepare nanocapsules. A solute often crystallizes when its solubility alters from one solvent to another, and its firstborn crystals are used as templates to prepare nanocapsules for the first time, which is called firstborn microcrystallization method. By using this method, the maximum diameter of the nanocapsules including artesunate is about 76 nm, and wrapping state is well.
BACKGROUND & OBJECTIVES: With the current snags from the use of Artemisinin - combination therapies (ACTs) in malaria treatment in addition to fear of cross- resistance to unrelated drugs, raising the immunocompetence of individuals in malaria endemic areas by vaccination is the best approach to malaria - free world. METHODS: Water - soluble cationic derivative, N, N, N- trimethylchitosan (TMC) was synthesized from chitosan.
The particle sizes of pharmaceutical substances are important for their bioavailability. Bioavailability can be improved by reducing the particle size of the drug. In this study, artemisinin was micronized by the rapid expansion of supercritical solutions (RESS). The particle size of the unprocessed white needle-like artemisinin particles was 30 to 1200 ?m. The optimum micronization conditions are determined as follows: extraction temperature of 62 °C, extraction pressure of 25 MPa, precipitation temperature 45 °C and nozzle diameter of 1000 ?m.

BACKGROUND: Artemisinin is the major sesquiterpene lactones in sweet wormwood (Artemisia annua L.), and its combination with transferrin exhibits versatile anti-cancer activities. Their non-selective targeting for cancer cells, however, limits their application. The aim of this study was to prepare the artemisinin and transferrin-loaded magnetic nanoliposomes in thermosensitive and non-thermosensitive forms and evaluate their antiproliferative activity against MCF-7 and MDA-MB-231 cells for better tumor-targeted therapy.
