The enzymatic and vitagen properties of unsaturated fats as they influence the differentiation of certain plant tissues

Abstract: AS A continuation of earlier work by the author, the present paper elaborates upon the internal distribution of unsaturated fats and associated enzymes in relation to the differentiation of certain types of plant cells. The formation and deposition of unsaturated fats are predominantly localized in the epidermis, hypodermis, endodermis, mestome or bundle sheath, trabecular cells and integument cells, all of which are essentially dermal structures. Certain characteristic physico-chemical relations in and near these dermal structures evidently underlie their structural differentiation. Special consideration is given to the reactions which determine whether or not an endodermis is formed. Incidental reference is made to the functional role of the endodermis. Preliminary work on certain vitamins as they influence the vitagen (Rosenberg, 1942) action of unsaturated fats in the development of some tissues is reported. GENERAL NATURE AND DETECTION OF THE FAT SYSTEM IN DERMAL TISSUES.-It is generally recognized that unsaturated fats have a tendency to oxidize. Several workers have demonstrated that this oxidation may be accelerated by an unsaturated fat oxidase system (Tauber, 1940; Strain, 1941; and Van Fleet, 1942b, 1943). The rate of oxidation of fats may be influenced by the hydrion concentration and by various pro-oxidants and antioxidants (Bradway and Mattill, 1934; Olcott and Mattill, 1936; and Van Fleet, 1942b). For a complete description of the exact mechanism of fat oxidation in plant tissue see Van Fleet, 1942b. The oxidation system in dermal tissues may be detected by application of buffered alkaline solutions (pH 7.8-8.2) and suitable indicators to fresh or frozen freehand or sliding microtome sections. The indicators found to be best adapted to this work are guaiacol, the reduced or leuco form of thionin, leuco methylene blue, leuco indigo carmine, leuco cresyl blue, "Nadi" and "Dopa." Through the application of alkali, particularly sodium selenite (Van Fleet, 1942b, 1943), the unsaturated fats are freed from inhibitols so that immediate oxidation takes place, and at the same time oxidation in other surrounding tissues is held in an inactivated state by the alkali. The term inhibitol is used here to denote all naturally occurring substances that are alkali-labile and related to a-tocopherol (Golumbic, 1941) or other possible unknown vitamin or related substances (see Mattill and co-workers). The term antioxidant signifies all artificially introduced or naturally occur-

Do mirror neurons explain misattribution of emotions in music

Abstract: It is speculated that certain listeners' misattribution of anger in the music of avant garde jazz saxophonists could be explained by the activity of mirror neurons. There is a neurological basis for the human tendency to imitate what is perceived in another person. This may lead to an inference that whatever comparable activity would be required to achieve a similar condition in the imitator is the condition being experienced by the person being imitated.

Altruistic Leadership Strategies in Coaching: A Case Study of Jim Tressel of The Ohio State University.

Abstract: StrAtegieS 9 Intercollegiate and high school coaches are faced with the difficult challenge of representing their school in a positive way. How a coach represents the school may be determined by his/her underlying motivation for coaching. Coaches may be driven by a variety of factors, such as: winning, financial success, or improving the well-being of the student-athletes. With a number of coaches choosing to leave their universities for higher paying positions and a number of coaches at the high school level involved in confrontations with officials or parents, questions arise about coaches’ primary motivation taking precedent over student-athletes’ well-being. However, the altruistic motivation of coaches is often overlooked by critics when so much focus is dedicated to the negatives.

Evolving Empire: America’s “Emirates” Strategy in the Persian Gulf

Abstract: This article examines U.S. policy in the Persian Gulf and juxtaposes American efforts in Iraq with those in the Gulf Cooperation Council states. As the U.S.-led effort to pacify and democratize Iraq continues to founder and with civil war underway in parts of the country, Washington pursues another imperial strategy in the Persian Gulf better suited to American security preferences and more likely to succeed, at least in the short term. In pursuing an “emirates” strategy, Washington seeks to indulge its historic preference for an informal empire in the Gulf that relies on cooperation with pro-American monarchs. While the Bush administration has touted Iraq’s potential to remake the Middle East into a democratic haven, America seems prepared to rely on familiar autocrats to help it tackle terrorists in Southwest Asia and preserve Western access to critical supplies of hydrocarbons should Iraq’s democratic rehabilitation prove unsuccessful.
