Polyclonal antibodies raised in Balb-c mice against BnSP-7, a Lys-49 phospholipase A2, were used to measure cross reactivity against other snake venoms. Using ELISA, these antibodies were able to recognize PLA2s isoforms present in venoms of botropic snakes at 1:6400, 1:3200 and 1:100 ratios (w/w). These antibodies highly recognized proteins of low molecular weight (∼14,000) from crude snake venom Bp and Bm by Western Blotting. PLA2 these venoms, by alignment of primary structures demonstrated high identity with BnSP-7 PLA2, especially in the C-terminal region...

Gadolinium as gadolinium nitrate is used as neutron poison in the moderator system for regulating and controlling the power generation of Pressurized Heavy Water Reactors (PHWR) and proposed to be used in Advanced Heavy Water Reactors (AHWR) owing to its high neutron absorption cross section. Removal of the added gadolinium nitrate (Gd(3+) and NO3(-)) from the system after its intended use is done using ion exchange resins. In the present investigation, attempts have been made to optimize the ion exchange process for generation of low radioactive waste and maximize utilization of the ion exchange resins by employing different types of resins and different modes of operation...

An immune response to triatomine’s saliva is an immunological marker of exposure to triatomine bites. However, considerable variability in salivary protein profiles did exist among species. In the present work, we compare salivary proteins from Mexican Triatoma dimidiata and Rhodnius prolixus using 2-D electrophoresis. A clear differential saliva profile was found to exist between these two triatomine species. Fewer protein spots were detected in R. prolixus than in T. dimidiata. More than half of the proteins had an isoelectric point between 5 and 7 and a molecular weight between 10 and 30 kDa in T...

A gyrB gene is present in the majority of bacterial species, and encodes the ATPase domain of DNA gyraseB-subunit protein, which is essential for transcription and replication of bacteria. The gyrB gene exhibits higher nucleotide sequence variability than the 16S rDNA gene and thus could be more reliable in differentiating Serratia fonticola. A species-specific primer pair and probe were designed for quantitative real-time PCR detection of S. fonticola using gyrB as the target gene. Nine members of the Serratia family (representing nine Serratia species) were chosen to verify the specificity of the primers...

In vivo variable-chlorophyll-fluorescence measurements of PSII quantum yields in optically dense systems are complicated by steep tissue light gradients due to scattering and absorption. Consequently, externally measured effective PSII quantum yields may be composed of signals derived from cells differentially exposed to actinic light, where cells located deeper inside tissues receive lower irradiance than cells closer to the surface, and can display distinct photophysiological status. We demonstrate how measured distributions of PSII quantum yields in plant tissue change under natural tissue light gradients as compared to conventionally measured quantum yields with even exposure to actinic light...

Salinity is an important abiotic stress affecting rice production worldwide. Development of salt tolerant varieties is the most feasible approach for improving rice productivity in salt affected soils. In rice, seedling stage salinity tolerance is crucial for better crop establishment. Quantitative trait loci (QTL) mapping using introgression lines (ILs) is useful for identification and simultaneous transfer of desirable alleles into elite genetic background. In the present study, 138 ILs derived from the cross between a high yielding elite salt susceptible japonica rice cultivar Jupiter and a salt tolerant indica landrace Nona Bokra were evaluated for salt tolerance at seedling stage in a hydroponics experiment and were genotyped using 126 simple sequence repeat markers...
