Abstract The current investigation entail systematic Quality by Design (QbD)-enabled approach for the development of Sustained released embedded drug delivery systems of L-Arginine employing ionic gelation technique to attain improved patient compliance. Hence, in this QbD enabled systematic approach; quality target product profile (QTTP) was defined and critical quality attributes (CQAs) were identified. Further the risk assessment studies were undertaken through Ishikawa fish bone diagram to locate the critical material attributes (CMAs) and/or critical process parameters (CPPs) for the formulation of beads that may affect CQAs of drug product. A face centered central composite design (CCD) for two factors at three levels each with α =1 was employed for the optimization process to checkout the impact of concentration of sodium alginate and concentration of chitosan as CMAs which wereprior identified from risk assessment study and further evaluated for CQAs viz. bead size, swelling index and percent drug entrapment. The optimum formulation was embarked upon by using mathematical model being developed yielding desired CQAs. Thereby chitosan coated calcium-alginate delivery system was successfully developed by strategically employing QbD approach.In a nutshell, the presentinvestigation reports the successful development of optimized chitosan coated alginate beads employing QbD approach which can serve as a platform for other drugs too.

Abstract: Cross-Lingual Information Retrieval (CLIR) enables a user to query to the different language target documents. CLIR incorporates a Machine Translation (MT) technique which is in growing state for Indian languages due to the unavailability of enough resources. In this paper, a Statistical Machine Translation (SMT) system is trained on two parallel corpora separately. A large English language corpus is used for language modeling in SMT. Experiments are evaluated by using BLEU score, further, these experimental setups are used to translate the Hindi language queries for the experimental analysis of Hindi-English CLIR. Since SMT does not deal with morphological variants while the proposed Translation Induction Algorithm (TIA) deals with that, therefore, TIA outperforms the SMT systems in perspective of CLIR.

Objetivo: La vía oral siempre ha sido la ruta preferida de administración de fármacos en muchas enfermedades y hasta hoy es la primera forma investigada en el desarrollo de nuevas formas de dosificación. El principal problema en las formulaciones de fármacos orales es la baja y errática biodisponibilidad, lo que resulta fundamentalmente por la escasa solubilidad en agua, con lo que plantean problemas en su formulación. Para la administración terapéutica de los grupos activos lipófilos (BCS clase II drogas), las formulaciones a base de lípidos están teniendo cada vez más atención. Métodos: Con ese objetivo, a partir de los sitios web de PubMed, HCAplus, Thomson, y sus registros se utilizaron como fuentes principales para llevar a cabo la búsqueda de los artículos de investigación más importantes publicados sobre el tema. A continuación, la información fue analizada cuidadosamente, poniendo de relieve los resultados más importantes en la formulación y desarrollo de sistemas de administración de fármacos auto-emulsionante micro, así como su actividad terapéutica. Resultados: El sistema de administración de fármacos autoemulsionante (SMEDDS) ha ganado más atención debido a la mejorada que permite la reducción de la biodisponibilidad oral en dosis, los perfiles temporales más consistentes de la absorción del fármaco, la orientación selectiva de fármaco (s) hacia la ventana de absorción específica en el tracto gastrointestinal, y la protección del fármaco (s) desde el entorno poco receptivo en el intestino. Conclusiones: Este artículo proporciona una visión completa de SMEDDS como un enfoque prometedor para abordar eficazmente el problema de moléculas poco solubles.

Aim: Oral route has always been the favorite route of drug administration in many diseases and till today it is the first way investigated in the development of new dosage forms. The major problem in oral drug formulations is low and erratic bioavailability, which mainly results from poor aqueous solubility, thereby pose problems in their formulation. For the therapeutic delivery of lipophilic active moieties (BCS class II drugs), lipid based formulations are inviting increasing attention. Methods: To that aim, from the web sites of PubMed, HCAplus, Thomson, and Registry were used as the main sources to perform the search for the most significant research articles published on the subject. The information was then carefully analyzed, highlighting the most important results in the formulation and development of self-micro emulsifying drug delivery systems as well as its therapeutic activity. Results: Self-emulsifying drug delivery system (SMEDDS) has gained more attention due to enhanced oral bio-availability enabling reduction in dose, more consistent temporal profiles of drug absorption, selective targeting of drug(s) toward specific absorption window in GIT, and protection of drug(s) from the unreceptive environment in gut. Conclusions: This article gives a complete overview of SMEDDS as a promising approach to effectively deal with the problem of poorly soluble molecules.

Entamoeba histolytica can infect any organ of the body, but only one case of renal involvement has been reported till now in the literature. We report a rare case of amoebic renal cyst in a 78-yearshowing favorable outcome with metronidazole treatment and therapeutic drainage.
