Sarcoidosis Presenting as Acute on Chronic Liver FailureReport of the First Case

Sarcoidosis is a multi system disease with different clinical presentations. Asymptomatic presentation is the commonest, but others include jaundice with chronic cholestasis, cirrhosis, portal hypertension, hepatic venous outflow tract obstruction and extrahepatic biliary obstruction. Cirrhosis and portal hypertension are the rarest manifestation of hepatic sarcoid and represent less than 1% of all cases. Acute on chronic liver failure as a presentation of sarcoidosis has never been reported before. Here we present a patient of sarcoidosis presenting with acute on chronic liver failure, and in whom, steroid therapy improved liver failure with a good outcome. [Med-Science 2016; 5(2.000): 655-65

Isolation and Characterization of a marine bacterium belonging to the genus <i style="">Alkaligenes </i>capable of the complete mineralization of the dibenzothiophene

391-397Following enrichment on benzoate five bacterial isolates capable of aerobic growth on dibenzothiophene were obtained from sea water collected off the west coast of India near the city of Goa. Sampling location had been previously contaminated with furnace oil spilled from a tanker. Classified as marine bacteria by their requirement for and optimum growth on 3% NaCl, all the isolates were identified by morphological observations and biochemical tests as belonging to the genes Alkaligenes. A single isolates producing intense red pigmented colony when growing on dibenzothiophene was chosen for further studies and designated as Strain JR110. During catabolism of dibenzothiophene intermediates were observed after initial dissolution and complete mineralization was achieved. JR110, independently confirmed as belonging to the genus Alkaligenes by Im Tech, India was deposited in their culture collection as MTCC3317

Dielectric characterization and polarimetric analysis of lunar north polar crater Hermite-A using Chandrayaan-1 Mini-SAR, Lunar Reconnaissance Orbiter (LRO) Mini-RF, and Chandrayaan-2 DFSAR data

Studies of the lunar surface from Synthetic Aperture Radar (SAR) data have played a prominent role in the exploration of the lunar surface in recent times. This study uses data from SAR sensors from three Moon missions: Chandrayaan-1 Mini-SAR, Lunar Reconnaissance Orbiter (LRO) Mini-RF and Chandrayaan-2 Dual Frequency Synthetic Aperture Radar (DFSAR). DFSAR sensor is the first of its kind to operate at L-band and S-band in fully and hybrid polarimetric modes. Due to the availability of only L-band data out of the two bands (L-and S-band) for the study site, this study only used DFSAR's L-band data. The dielectric characterization and polarimetric analysis of the lunar north polar crater Hermite-A was performed in this study using Chandrayaan-1 Mini-SAR, LRO Mini-RF and Chandrayaan-2 DFSAR data. Hermite-A lies in the Permanently Shadowed Region (PSR) of the lunar north pole and whose PSR ID is NP_879520_3076780. Because of its location within the PSR of the lunar north pole, the Hermite-A makes an ideal candidate for a probable location of water-ice deposits. This work utilizes S-band hybrid polarimetric data of Mini-SAR and Mini-RF and L-band fully polarimetric data of DFSAR for the lunar north polar crater Hermite-A. This study characterizes the scattering mechanisms from three decomposition techniques of Hybrid Polarimetry namely m-delta, m-chi, and m-alpha decompositions, and for fully polarimetric data Barnes decomposition technique was applied which is based on wave dichotomy. Eigenvector and Eigenvalue-based decomposition model (H-A-Alpha decomposition) was also applied to characterize the scattering behavior of the crater. This study utilizes the hybrid-pol and fully polarimetric data-based Integral Equation Model (IEM) to retrieve the values of dielectric constant for Hermite-A crater. The dielectric constant values for the Hermite-A crater from Chandrayaan-1 Mini-SAR and LRO Mini-RF are similar, which goes further in establishing the presence of water-ice in the region. The values of the dielectric constant for Chandrayaan-2 in some regions of the crater especially on the left side of the crater is also around 3 but overall the range is relatively higher than the compact/hybrid polarimetric data. The dielectric characterization and polarimetric analysis of the Hermite-A indicatively illustrate that the crater may have surface ice clusters in its walls and on some areas of the crater floor, which can be explored in the future from the synergistic use of remote sensing data and in-situ experiments to confirm the presence of the surface ice clusters
