Regulation Of Protein Synthesis By Leucine And Amino Acid Balance., John Patrick Mcgowan
Regulation Of Protein Synthesis By Leucine And Amino Acid Balance., John Patrick Mcgowan
University of the Pacific Theses and Dissertations
The effects of a physiologically balanced mixture of amino acids on the synthesis of proteins has been investigated. The roles of leucine and tryptophan, both implicated in the regulation of protein synthesis, were also studied. The balance of amino acids is important under specific rate-limiting conditions; the physiological balance "protects" the protein synthesizing system from the stressed condition of leucine limitation. Leucine is an important regulator of protein synthesis and the tryptophan effect on translation is dependent on the concentration of leucine. Thus tryptophan is a secondary regulator. The relative concentration of amino acids, described as balance, alterned the synthesis …
In Vitro Percutaneous Penetration Of Methotrexate, Rajaram Vaidyanathan
In Vitro Percutaneous Penetration Of Methotrexate, Rajaram Vaidyanathan
University of the Pacific Theses and Dissertations
This research project was designed to investigate the effects of various physical and chemical parameters on percutaneous penetration of methotrexate. The potential of propylene glycol in water as a vehicle for topical delivery of methotrexate has been examined. A detailed examination of solubility, partition coefficient and pH parameters in the range of 2 to 6 pH units has been conducted with the goal of correlating their effects on skin penetration of methotrexate. The importance of physiochemical parameters such as solubility and partition coefficient and their aid in the development of a suitable delivery system for topical application has been explained. …
Brunfelsia Hopeana - Pharmacologic Screening: Isolation And Characterization Of Hopeanine, Radhakrishnan Parameswaran Iyer
Brunfelsia Hopeana - Pharmacologic Screening: Isolation And Characterization Of Hopeanine, Radhakrishnan Parameswaran Iyer
University of the Pacific Theses and Dissertations
The genus Brunfelsia (Fam. Solannceae) comprises some 40 species of shrubs native to South Africa and West Indies. Brunfelsia hopeana (common name: Manaca root) and related species are recognized in folk medicine in South America as being useful as diuretic, antirheumatic, antisyphilitic agents and as narcotic hallucinogens. In view of the interesting folkloric uses and a paucity of chemical and pharmacological investigation of B. hopeana, a systematic phytochemical and pharmacological investigation on B. hopeana was undertaken in our laboratory.
Hippocratic screening of the whole root powder and extracts of B. hopeana administered intrapcritonially to rats, indicated that the whole root …
Comparative Phytochemistry Of Saururaceae Essential Oils., Lohit Venkateswara Tutupalli
Comparative Phytochemistry Of Saururaceae Essential Oils., Lohit Venkateswara Tutupalli
University of the Pacific Theses and Dissertations
In view of their native medicinal uses, a systematic investigation of the phytochemistry and Hippocratic screening of three members of the Saururaceac namely, Anemopsis californica, Saururus cernuus and Houttuynia cordata was undertaken.
