The sero-surveillance and immunization studies on Peste des Petits Ruminants (PPR) in non-descriptive indigenous sheep and Black Bengal goats aged between 5 to 12 months were carried out in the district of Mymensingh during the period from June to November 2003. Sero-prevalence of PPR by using competitive enzyme linked immunosorbent assay (C-ELISA) was conducted on 100 sheep and 100 goats which...

The pentatricopeptide repeat (PPR) gene family, with hundreds of members in land plant genomes, has been recognized as a tremendous resource for plant phylogenetic studies based on publicly available genomic data from model organisms. However, whether this appealing nuclear gene marker system can be readily applied to non-model organisms remains questionable, particularly given the potential un...

Pentatricopeptide repeat (PPR) proteins compose a family of nuclear-encoded transcriptional regulators of cytoplasmic genes. They have shown dramatic expansion in copy number in plants, and although the functional importance of many remains unclear, a subset has been repeatedly implicated as nuclear restorers for cytoplasmic male sterility. Here we investigate the molecular population genetics ...

Four hundred and fifty-eight genes coding for PentatricoPeptide Repeat (PPR) proteins are annotated in the Arabidopsis thaliana genome. Over the past 10 years, numerous reports have shown that many of these proteins function in organelles to target specific transcripts and are involved in post-transcriptional regulation. Therefore, they are thought to be important players in the coordination be...

Developing murine growth plates comprise at least three morphologically distinct groups of chondrocytes (see Fig. 3C): round periarticular chondrocytes, flat columnar chondrocytes and hypertrophic chondrocytes. Periarticular chondrocytes proliferate and differentiate into columnar chondrocytes that proliferate further and form orderly columns. Unlike the round periarticular chondrocytes, the fl...

Lyophilization stabilizes the biological materials by using two overlapping drying procedure i.e. primary drying by sublimation of the ice crystal from frozen material and secondary drying or desorption by evaporation of the free water adsorbed into the dried product. Three different stabilizers i.e. lactalbumin hydrolysate-sucrose, Weybridge medium and lactalbumin hydrolysate-manitol were used...

Intermittent Photic Stimulation (IPS) is a well recognized provocation maneuver during EEG recording which helps in identifying underlying photosensitivity. The frequency and characteristics of various responses to photosensitivity among our adult patients was determine. EEGs of subjects > or =15 years from 2003-2006, were reviewed. Two main photosensitive responses were observed: Photoparoxysm...

Perennial ryegrass (Lolium perenne L.) is widely used for forage production in both permanent and temporary grassland systems. To increase yields in perennial ryegrass, recent breeding efforts have been focused on strategies to more efficiently exploit heterosis by hybrid breeding. Cytoplasmic male sterility (CMS) is a widely applied mechanism to control pollination for commercial hybrid seed p...
