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.

Covalent modifications of titanium with small molecules known to promote human osteoblast maturation are especially attractive in developing superior biomaterials. An important step in securing competent bone formation at implant sites is promoting the formation of mature osteoblasts, either from committed pre-osteoblasts or from their mesenchymal progenitors.

Laboratory study was conducted on the biology of the phorid fly Megaselia sacalaris. The influence of 3 constant temperatures and various larval densities was researched in the laboratory as these relate to mean life stage rate of development and survival. Flay development on a synthetic diet at 25 degrees C. 75=2% RH and 18 hr photophase was used as the standard. Mean times for development and survival were egg incubation 16.3 h (97.6%); larval period 7.3 days (97.6%); pupal period 9.8 days (95.8%, 91.6%); adult longevity 29.9 days, 24.8 days. Fecundity was 664.8 eggs.

AIM: To study the effect of artemether (Art) on the tegument of schistosomes. METHODS: Mice infected with S japonicum cercariae for 7 and 35 d, or with S mansoni cercariae for 49 d were treated intragastrically with Art 200-300 mg.kg-1.d-1 for 2 d. Schistosomes were collected in groups of 2 mice at various intervals after medication for scanning electron microscopic observation. RESULTS: The tegumental changes induced by Art appeared to be similar in S japonicum and S mansoni: swelling and fusion of tegumental surfaces, vesicle formation and collapse of discoid-like sensory structures.

OBJECTIVES: To study the fasciocidal properties of artesunate and artemether in the rat model and in vitro. METHODS: Adult Fasciola hepatica were exposed in vitro to 1, 10 and 100 microg/mL of artesunate, artemether and dihydroartemisinin for 72 h. Female Wistar rats were administered a single oral dose of artesunate and artemether (100-400 mg/kg) commencing 3 or 10-14 weeks post-infection and worm burden reductions were assessed against infected but untreated control rats.

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.

Artemisinin, a poorly water-soluble antimalarial drug, presents a low and erratic bioavailability upon oral administration. The aim of this work was to study an agglomerated powder dosage form for oral administration of artemisinin based on the artemisinin/?-cyclodextrin primary microparticles. These primary microparticles were prepared by spray-drying a water-methanol solution of artemisinin/?-cyclodextrin. ?-Cyclodextrin in spray-dried microparticles increased artemisinin water apparent solubility approximately sixfold.

The polycarbonate copolymer poly(trimethylene carbonate-co-5,5-dimethyl trimethylene carbonate) (P(TMC-co-DTC)) was synthesized by the polymerization of trimethylene carbonate (TMC) and 5,5-dimethyl trimethylene carbonate (DTC) using tin (II) 2-ethylhexanoate [Sn(Oct)(2)] as a catalyst. In vitro degradation tests indicated this polycarbonate copolymer degraded slowly in phosphate buffer saline solution (PBS, 0.1 mol/L, at 37°C).

Praval bhasma (PB; Coral calx) is a natural source of rich calcium widely used in traditional system of Indian medicine as a supplement in the treatment of variety of bone metabolic disorders associated with calcium deficiency. The present study was designed to investigate the inhibitory effects of Praval bhasma on the progress of bone loss induced by ovariectomy and concurrent calcium deficiency (CD-OVX).

OBJECTIVE: To prepare the Praval bhasma (PB) and to perform its characterization. METHODS: The preparation was performed strictly as per method prescribed in Ayurvedic formulary of India followed by preliminary tests including Nischandratva, Rekhapurnatvam, Varitaramtavm, Nisvadutvam and Amla pariksha. The physicochemical characterization was done with the use of instrumental techniques such as Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X ray diffraction (XRD), and energy dispersive X-ray (EDAX).
