Microsatellites are TRs of base pairs that are widely spread throughout the genome. Microsatellites are located in the coding and noncoding regions. Microsatellite markers are codominant, abundant, and multiallelic and play an important role in the study of molecular population genetics, positional cloning, QTL mapping, disease identification, pathogenesis, and evolutionary studies, etc. Here we have discussed the origin and types of microsatellites, their genomic distribution, and their functional significance in the microbial genome.

Ten isolates of Pyricularia oryzae causing rice blast disease were evaluated for their morphological, pathogenic, virulence and genetic characterization using RAPD marker. Isolates were classified into three groups based on pathogenicity viz. severely pathogenic, moderately pathogenic and mildly pathogenic and also into four another gropus i.e. PG-I, PG-II, PG-III and PG-IV based on cultural & morphological characteristics. The molecular polymorphism among isolates by means were analyzed by means of RAPD-PCR and the genetic coefficient matrix derived from the scores of the RAPD profile showed that minimum and maximum per cent similarities among isolates were in the range of 80 to 35 percent respectively. The cluster analysis by unweighted pair group method with arithmetic average (UPGMA) separated the isolates into tw...

Moreover, the yield of dimer is unchanged upon varying the temperature over the range studied in the experiments. Earlier molecular simulation studies showed a significant increase in dimer formation in carbon nanopores, but the dimer yield was considerably less than that found in the experiments, and decreased rapidly as the temperature was raised. Here, we report an ab initio and molecular simulation study of this reaction in both slit-shaped pores and single-walled carbon nanotubes. The ab initio calculations show that the nitric oxide dimer forms a weak chemical bond with the carbon, and the bonding energy is more than 20 times stronger than the van der Waals energy assumed in the previous studies...

The scope of published research on WoM is broad and spans a long period of time. However, it is not since the advent of social media that WoM or electronic-Word of Mouth (e-WoM) has become a measurable means of communication, making work on e-WoM recent and scarce. Also, existing work pertains to developed economies and there is a potential scope of study in the context of developing nations like India, where the focus is shifting to digitalization in a huge way. To understand the impact of WoM and social media, an attempt has been made to divide literature into drivers, measures, and effects of WoM. Number of variables emerge and can be used to measure the three identified categories. These variables can also be consolidated to establish causal links between drivers and effects of WoM. WoM has been conceptualized as the traditional ...

Detection and accurate identification of harmful plant pathogens is very essential to improve the strategies for controlling plant diseases. The early detection and identification of plant pathogens provides the basis for understanding their biology and appropriate strategies to control that particular pathogen. For the identification of plant pathogen, traditional procedures, i.e., isolation, in vitro culturing and microscopy of the extracellular pathogens, are in common routine. However, traditional methods may take days or weeks for particular pathogens to produce diagnostic spores. Indexing for many intracellular pathogens is also very complex because they are obligate biotrophs in nature. The development in the recent tools in molecular biology has enhanced and accelerated the detection and diagnostics through the automatic purification of nucleic acids and specific proteins from pathogens.

Only 1% of all extracranial schwannomas show that intraoral occurrence with tongue is the commonest site and retromolar region is the least common site. It presents as encapsulated, slow growing, solitary, smooth-surfaced, usually asymptomatic tumor. We report a case of 70-year-old male with well-defined mass on left retromolar region which was painless and slow growing. Diagnosis is made by histological examination and immunohistochemistry analysis to confirm the neural tissue origin of the lesion. The treatment is complete surgical excision of the lesion without recurrence.

More than one hundred million people are reported to be exposed to elevated concentrations of arsenic mainly via drinking water. Essential trace elements can affect toxicity of metals by interacting with metals at the primary site of action and can also modify the body's response to toxic metals by altering their metabolism and transport. This study investigates the effects of concomitant administration of selenium, magnesium, and calcium with arsenic on blood biochemistry and oxidative stress. Selenium was the most effective in reducing arsenic-induced inhibition of blood δ-aminolevulinic acid dehydratase (ALAD) activity and liver oxidative stress. Calcium and magnesium also showed favourable effects on haematological and other biochemical parameters. Because selenium was the most effective, it should b...
