A green one step facile synthesis of graphene nanosheets by Terminalia chebula (T. chebula) extract mediated reduction of graphite oxide (GO) is reported in this work. This method avoids the use of harmful toxic reducing agents. The comparative results of various characterizations of GO and T. chebula reduced graphene oxide (TCG) provide a strong indication of the exclusion of oxygen containing groups from graphene oxide and successive stabilization of the formed reduced graphene oxide (RGO).

BACKGROUND: Breast cancer is the most common cancer diagnosed among women and is the second leading cause of cancer death. Homeopathic medicines are part of the alternative medicines that are given as a supportive therapy in breast cancer. The objective of this study was to investigate the anticancer activity of commercially available homeopathic preparations of Terminalia chebula (TC) and evaluate their nanoparticulate nature.

Nanopreparations such as liposomes, micelles, polymeric and inorganic nanoparticles, and small molecule/nucleic acid/protein conjugates have demonstrated various advantages over "naked" therapeutic molecules. These nanopreparations can be further engineered with functional moieties to improve their performance in terms of circulation longevity, targetability, enhanced intracellular penetration, carrier-mediated enhanced visualization, and stimuli-sensitivity.

Stem cells are increasingly the focus of translational research as well as having emerging roles in human cellular therapy. To support these uses there is a need for improved methods for in vivo cell localization and tracking. In this study, we examined the effects of cell labeling on the in vitro functionality of human adipose-derived mesenchymal stem cells. Our results provide a basis for future in vivo studies investigating implanted cell fate and longevity.

The main objective of this research is to improve the dissolution rate of artemisinin (ART) by fabrication with ?-cyclodextrin (?-CD) as a hydrophilic carrier. Artemisinin nanoparticles and ART/?-CD complexes were successfully fabricated by means of evaporative precipitation of nanosuspension. Characterization of the samples was done by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and dissolution tester.

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.

Artemisinin (ART) dimers show potent anti-proliferative activities against breast cancer cells. To facilitate their clinical development, novel pH-responsive artemisinin dimers were synthesized for liposomal nanoparticle formulations. A new ART dimer was designed to become increasingly water-soluble as pH declines. The new artemisinin dimer piperazine derivatives (ADPs) remained tightly associated with liposomal nanoparticles (NPs) at neutral pH but were efficiently released at acidic pH's that are known to exist within solid tumors and organelles such as endosomes and lysosomes.

Extensive research within the last two decades has revealed that most chronic illnesses, including cancer, diabetes, and cardiovascular and pulmonary diseases, are mediated through chronic inflammation. Thus, suppressing chronic inflammation has the potential to delay, prevent, and even treat various chronic diseases, including cancer.

The Institute of Holistic Medical Sciences (IHMS), Kottayam, Kerala, India, the Institute of Macromolecular Science and Engineering (IMSE), Kottayam, Kerala, India and Mathew Ayurveda und Venen Klinik (MUVK), Klagenfurt, Austria, have jointly conducted a 3-day world conference on nanomedicine and drug delivery (WCN 2010) in Kottayam, Kerala, India from 16-18 April 2010. Nanomedicine is defined as the application of nanotechnology to achieve breakthroughs in healthcare. It exploits the improved and often novel physical, chemical and biological properties of materials at the nanometer scale.
