Effect of and in the management of polycystic ovary syndrome in Wistar rats.

Objective: Research has shown that polycystic ovary syndrome (PCOS) is a common cause of infertility in women. The drugs used to treat PCOS tend to manage the symptoms rather than cure the disease. Furthermore, these drugs have severe side-effects and influence the quality of life for the patients.

Nannochloropsis Extract-Mediated Synthesis of Biogenic Silver Nanoparticles, Characterization and In Vitro Assessment of Antimicrobial, Antioxidant and Cytotoxic Activities.

Objective: To investigate the biogenic synthesis of silver nanoparticles (AgNPs) using partially purified ethyl acetate extract of Nannochloropsis sp. hexane (EAENH) fraction of microalga. Methods: The green synthesis of AgNPs was confirmed with UV-Vis spectrum which shows the surface plasmon resonance (SPR) at 421 nm.

Shielding Therapeutic Drug Carriers from the Mononuclear Phagocyte System: A Review.

The mononuclear phagocyte system (MPS) defends the body against the invasion of microorganisms by phagocytosis. In the presence of opsonins, the invading matter is readily recognized by phagocytes because of the interaction between receptors on the phagocytic cell surfaces and the modified conformation of opsonins. The particulate carriers, which are otherwise capable of optimizing drug delivery, are subjected to opsonization and phagocytosis by the MPS immediately following intravenous administration.

Occurrence of drug-drug interactions in Adama Referral Hospital, Adama city, Ethiopia.

Objective: Many medications have potential interactions with other drugs or substances when prescribed together. This study was intended to investigate the extent of poly-pharmacy, event of drug-drug interactions and associated ADRs in Adama Referral Hospital, Oromia regional State, Ethiopia to create awareness of potential drug interactions and for development of clinical strategies to prevent the occurrence of DDIs.

Methods: A retrospective study was done at Adama Referral hospital, Adama city, Ethiopia during March-May 2014.

Nanotechnology: an effective tool for enhancing bioavailability and bioactivity of phytomedicine.

To achieve the desired therapeutic objective, the drug product must deliver the active drug at an optimal rate and amount. By proper biopharmaceutic design, the rate and extent of drug absorption (also called as bioavailability) or the systemic delivery of drugs to the body can be varied from rapid and complete absorption to slow and sustained absorption depending upon the desired therapeutic objective. Phytomedicine have served as the foundation for a larger fraction of the current pharmacopeia.

Silver nanoparticles as real topical bullets for wound healing.

Nanotechnology is on the threshold of providing a host of new materials and approaches, revolutionizing the medical and pharmaceutical fields. Several areas of medical care are already profiting from the advantage that nanotechnology offers. Recently, silver nanoparticles are attracting interest for a clinical application because of its potential biological properties such as antibacterial activity, anti-inflammatory effects, and wound healing efficacy, which could be exploited in developing better dressings for wounds and ulcers.

Triamcinolone-loaded glutaraldehyde cross-linked chitosan microspheres: prolonged release approach for the treatment of rheumatoid arthritis.

The use of glucocorticoids in the treatment of rheumatoid arthritis has been widely employed, but, owing to their systemic side-effects and also their susceptibility to the first pass metabolism, their use is being discouraged. To circumvent this, triamcinolone (TA) were encapsulated in chitosan microspheres with glutaraldehyde as the cross-linking agent to achieve a prolonged drug release. The percentage of drug loading, encapsulation efficiency, and surface morphology by Scanning electron microscopy (SEM), Phase transition by Differential scanning colorimetry (DSC), as well as Fourier transform infrared spectroscopy (FTIR) studies was carried out to characterize the chitosan microspheres.

Biodegradation and biocompatibility of contraceptive-steroid-loaded poly (DL-lactide-co-glycolide) injectable microspheres: in vitro and in vivo study.

Purpose: A controlled-release drug delivery of contraceptive steroids levonorgestrel (LNG) and ethinyl estradiol (EE) has been developed by successful encapsulation of LNG and EE in poly (lactide-co-glycolide) (PLG) microspheres.

Materials And Methods: Smooth, spherical, steroid-loaded PLG microspheres with a mean size of 10-25 microm were prepared by using the water/oil/water double-emulsion solvent evaporation method.

Results: In vitro release profiles showed an increased burst release of LNG/EE on Week 1; thereafter, the release was sustained.

Characterization of polymeric poly(epsilon-caprolactone) injectable implant delivery system for the controlled delivery of contraceptive steroids.

Contraceptive steroids levonorgestrel (LNG) and ethinyl estradiol (EE) have been encapsulated with poly(epsilon-caprolactone) (PCL) microspheres using a w / o /w double emulsion method. The microspheres prepared were smooth and spherical, with a mean size from 8-25 microm. In vitro release profiles of microspheres showed a trend of increasing initially at the first week, and thereafter the release was sustained.

Influence of manufacturing parameters on development of contraceptive steroid loaded injectable microspheres.

The main objective of this work was to develop a system consisting of polymeric microspheres loaded with steroid drugs. The drugs were encapsulated using biodegradable poly(lactide-co-glycolide) (PLG) and poly(epsilon-caprolactone) (PCL) by double emulsion solvent evaporation method. The lipophilic drugs, levonorgestrel and ethinylestradiol were made soluble by adding ethanol/water mixture.
