Fluoride is known to cross the blood-brain barrier and alter the structure and function of neural tissue. There are few authoritative reports on neurodegenerative changes in hippocampus, neocortex, cerebellum, spinal cord and sciatic nerve in fluoride intoxication. We report the alterations in the structure of neuronal tissue after chronic administration of(More)
The effects of various Flustra foliacea metabolites on different types of human neuronal nicotinic acetylcholine receptors (nAChRs) expressed in Xenopus oocytes were investigated. Whereas most of the compounds tested had a small blocking effect, one of them, deformylflustrabromine, selectively increased the current obtained in alpha4beta2 receptors when(More)
This paper presents an ongoing Ph.D. thesis work which aims at improving the performance of read-only transactions (ROTs) in database systems using the notion of speculation. In the literature, speculative locking approach has been proposed to improve the transaction processing performance in online transaction processing environments. In this thesis, we(More)
AIMS/INTRODUCTION Diabetes is a major health concern throughout the world because of its increasing prevalence in epidemic proportions. β-Cell deterioration in the pancreas is a crucial factor for the progression of diabetes mellitus. Therefore, the restoration of β-cell mass and its function is of vital importance for the development of effective(More)
—In this paper we have proposed an improved approach to extract rare association rules. Rare association rules are the association rules containing rare items. Rare items are less frequent items. For extracting rare itemsets, the single minimum support (minsup) based approaches like Apriori approach suffer from " rare item problem " dilemma. At high minsup(More)
Speculative locking (SL) protocols have been proposed in the literature for improving the performance of read-only transactions (ROTs) without correctness and data currency issues. In these protocols, ROTs carry out speculative executions and update transactions (UTs) follow two-phase locking (2PL). In these protocols, UTs are blocked if they conflict with(More)
