BACKGROUND Periodontitis is one of the major reasons for tooth loss in adults. India, with a population of over 1 billion, is bound to become a developed nation soon. This transition will require a population that is healthy, including in terms of periodontal health. Early studies done in India gave an indication that the population is highly susceptible to(More)
Depression is a chronic, recurring and potentially life-threatening illness that affects up to 20% of the population across the world. Despite its prevalence and considerable impact on human, little is known about its pathogenesis. One of the major reasons is the restricted availability of validated animal models due to the absence of consensus on the(More)
BACKGROUND Caspase-independent apoptotic pathways are suggested as a mechanism for the delayed neuronal death following ischemic insult. However, the underlying signalling mechanisms are largely unknown. Recent studies imply the involvement of several mitochondrial proteins, including endonuclease G (EndoG) and Bcl-2/adenovirus E1B 19 kDa-interacting(More)
Nitric oxide (NO) and p38 have been shown to be involved in the ischemia/hypoxia-induced neuronal injury. In this study, we examined the activation patterns of mitogen-activated protein kinases and explored the relationship between NO and p38 in a model of hippocampal neuronal death induced by hypoxia/reoxygenation (H/R). p38 activity increased robustly(More)
We have developed 18F-fluoxetine as a radiotracer analog of the antidepressant drug fluoxetine (Prozac). In vitro saturation experiments of 18F-fluoxetine were carried out on rat midbrain tissue and citalopram was used for measuring nonspecific binding. A saturation curve for the binding of 18F-fluoxetine was not obtained. Even when fluoxetine (10 microM)(More)
OBJECTIVE The purpose of this study was to investigate and measure morphological changes in the vertebral canal and its cast form at the level of the cervical spine in vitro during flexion, extension, and lateral bending in cadaver specimens. METHODS The morphological changes of vertebral canal and its contents were investigated and measured during(More)
— In this paper, we have proposed a new variant of Round Robin scheduling algorithm by executing the processes according to the new calculated Fit Factor 'f' and using the concept of dynamic time quantum. We have compared the performance of our proposed Fittest Job First Dynamic Round Robin(FJFDRR) algorithm with the Priority Based Static Round Robin(PBSRR)(More)
The air-breathing singhi catfish (Heteropneustes fossilis) is frequently being challenged by different environmental insults such as hyper-ammonia, dehydration and osmotic stresses in their natural habitats throughout the year. The present study investigated the effect of hyperosmotic stress, due to exposure to hypertonic environment (300 mM mannitol) for(More)
Natural products represent a reservoir of diverse templates and are being tapped to outsource novel anticancer agents. Hemidesmus indicus R.Br.(Fam: Asclepidaceae) has been reported to be useful for the treatment of inflammation, cuts, wounds, burns, snake bite, skin and blood diseases, ulcers, immunological disorders. In the present study, the methanolic(More)
