Sympathetic Stimulation and Hypertension in the Pyridoxine-Deficient Adult Rat

Pyridoxal phosphate is the coenzyme of various decarboxylases involved in the formation of monoamine neurotransmitters such as y-aminobutyric acid , serotonin , dopamine, and norepinephrine . Adult male Sprague-Dawley rats placed on a pyridoxine -deficient diet for 8 weeks showed significant hypertension compared with pyridoxine -supplemented controls . Hypothalamic contents of pyridoxal phosphate , y-aminobutyric acid, and serotonin in the pyridoxine - deficient rats were significantly lower than those in pyridoxine -supplemented controls . Hypertension was associated with sympathetic stimulation . Treatment of pyridoxine-deficient rats with a single dose of pyridoxine (10 mg/kg body weight) reversed the blood pressure to normal levels within 24 hours, with concomitant restorations of hypothalamic serotonin and y-aminobutyric acid as well as the return of plasma norepinephrine and epinephrine to normal levels . Also, pyridoxine treatment reversed the hypothalamic hypothyroidism observed in pyridoxine -deficient rats . These results indicate an association between pyridoxine deficiency and sympathetic stimulation leading to hypertension.

A multiple-building diffraction attenuation function expressed in terms of UTD coefficients for microcellular communications

This work presents an explicit formulation for multiple- edge diffraction for mobile radiowave propagation in terms of uniform theory of diffraction (UTD) coefficients when a spherical incident wave is considered. This solution can be used in an UTD context and sharply reduces the computing time over existing formulation. Results can be applied in the planning of microcellular systems

Building Digital. Repository Of Project Reports: A Proposal for cusat

The effective organization and utilisation of resources produced by the students, faculty and research scholars in university departments assume greater significance. Institutional repositories are developed by many institutions to provide resources and materials that support students in their studies. The present study recognizes the value of such a repository in the Engineering and Technology discipline in Cochin University of Science and Technology. The paper explains the need for a digital repository ofproject reports. The authors present a modelfor digital repository, and the organization.and administration of such a repository. The study also analyses the various other factors associated with the proposed depository.

Sustainable Building Materials in Kerala – An Overview

Kerala, God’s own country is blessed with immense natural resources. It’s high time that the state’s natural resources being utilized effectively. While sustainable development is the need of the hour, we have to take lead in initiating activities that would minimize the exploitation of our natural resources resulting in their effective utilization. This paper narrates an overview of innovative building materials especially using natural fibres available in Kerala and discusses the feasibility of utilising such fibres in the context of sustainable building materials in Kerala. The paper also discusses how these materials can be effectively utilized to reduce the huge investment in the construction industry
