5Microsponge based drug delivery system for augmented gastroparesis therapy:Formulation development and evaluation显示文摘The intention behind the present work was to develop a microsponge based novel dosage form for sustained delivery of domperidone.Quasi-emulsion solvent diffusion method was employed using Eudragit RS-100 with various drug-polymer ratios for the preparation of microsponges.For optimization purposes,several factors which affect microparticles’physical properties were investigated.Characterization techniques followed for the formed microsponges were DSC,FTIR,SEM,XRD and particle size analysis,along with morphology,drug loading and in vitro drug release.It was found that there were no chemical interactions between drugs and polymers used as per DSC and FTIR results.The drug-polymer ratio showed remarkable impact on drug content,encapsulation efficiency and particle size.SEM micrographs revealed that microsponges were spherical in shape with porous surface,and had 104±0.22μm mean particle size.The microsponges were then loaded in capsules followed by in vitro drug release study;which depicted that microsponges with drug-polymer ratio of 1:2 were more proficient to give extended drug release of 76.38%at the end of 8 h,superior in contrast to conventional marketed formulation Domstal®,which got exhausted incredibly earlier by releasing 82.57%drug at the end of 1⁄2 h only.Hence,the developed microsponge based formulation of domperidone would be an expectant,promising substitute to conventional therapy of gastroparesis,emesis and alike gastric ailments.Riyaz Ali M.Osmani Nagesh H.Aloorkar Bharati U.Thaware Parthasarathi K.Kulkarni Afrasim Moin Umme Hani Atul Srivastava Rohit R.Bhosale 2015Asian Journal of Pharmaceutical Sciences2015,10,5:1

9Upper ocean high resolution regional modeling of the Arabian Sea and Bay of Bengal显示文摘In this paper, effort is made to demonstrate the quality of high-resolution regional ocean circulation model in realistically simulating the circulation and variability properties of the northern Indian Ocean(10°S–25°N,45°–100°E) covering the Arabian Sea(AS) and Bay of Bengal(BoB). The model run using the open boundary conditions is carried out at 10 km horizontal resolution and highest vertical resolution of 2 m in the upper ocean.The surface and sub-surface structure of hydrographic variables(temperature and salinity) and currents is compared against the observations during 1998–2014(17 years). In particular, the seasonal variability of the sea surface temperature, sea surface salinity, and surface currents over the model domain is studied. The highresolution model's ability in correct estimation of the spatio-temporal mixed layer depth(MLD) variability of the AS and BoB is also shown. The lowest MLD values are observed during spring(March-April-May) and highest during winter(December-January-February) seasons. The maximum MLD in the AS(BoB) during December to February reaches 150 m (67 m). On the other hand, the minimum MLD in these regions during March-April-May becomes as low as 11–12 m. The influence of wind stress, net heat flux and freshwater flux on the seasonal variability of the MLD is discussed. The physical processes controlling the seasonal cycle of sea surface temperature are investigated by carrying out mixed layer heat budget analysis. It is found that air-sea fluxes play a dominant role in the seasonal evolution of sea surface temperature of the northern Indian Ocean and the contribution of horizontal advection, vertical entrainment and diffusion processes is small. The upper ocean zonal and meridional volume transport across different sections in the AS and BoB is also computed. The seasonal variability of the transports is studied in the context of monsoonal currents.Dwivedi Suneet Mishra Alok Kumar Srivastava Atul 2019Acta Oceanologica Sinica2019,38,5:1

11The impact of northern Indian Ocean rivers on the Bay of Bengal using NEMO global ocean model显示文摘The effect of river runoff over the northern Indian Ocean(NIO) especially over the Bay of Bengal(Bo B) has been studied using global Nucleus for European Modelling of the Ocean(NEMO). Two sensitivity experiments, with and without river runoff are conducted and the influence of river runoff on the Indian Ocean hydrography,stratification and circulation features are studied. It is found that due to river runoff surface salinity over the northern Bo B decreases by more than 5 and the East India Coastal Current strengthens by 2 cm/s during post monsoon season. The fresh river water reaches up to 15°N in the Bo B and is the main cause for low salinity there.Sea surface temperature in the northwestern Bo B increases by more than 0.2℃ due to the river runoff in summer monsoon while surface cooling upto 0.2℃ is seen in north-west part of Bo B in winter season. The seasonal mixed layer depth in the region is found to be dependent on river runoff. The effect of vertical shear and Brunt Vaisala frequency on stratification is also examined. The ocean water becomes highly stratified up to 3 035 m due to the river runoff. It is found that the energy required for mixing is high in the northern and coastal Bo B.Atul Srivastava Anitha Gera Imran MMomin Ashis Kumar Mitra Ankur Gupta 2020Acta Oceanologica Sinica2020,39,3:0
