Meditative Practices

SUMMARY Meditation, a component of ashtanga yoga, is an act of inward contemplation in which the mind fluctuates between a state of attention to a stimulus and complete absorption in it. Some forms of meditation have been found to be useful for people with psychiatric conditions such as anxiety, depression and substance use disorder. Evidence for usefulness of meditation for people with psychotic disorders is mixed, with reported improvements in negative symptoms but the emergence/precipitation of psychotic symptoms. This article narrates the benefits of meditation in psychiatric disorders, understanding meditation from the yoga perspective, biological aspects of meditation and practical tips for the practice of meditation. We also explain possible ways of modifying meditative practices to make them safe and useful for the patient population and useful overall as a society-level intervention.

Abstract The present study aimed at elucidating the uptake and biotransformation of T2 and HT2 toxins in five cultivars of durum wheat, by means of cultured plant organs. An almost complete absorption of T2 toxin (up to 100 µg) was noticed after 7 days, along with the contemporaneous formation of HT2 in planta, whereas HT2 showed a slower uptake by uninfected plant organs. Untargeted MS-analysis allowed to identify a large spectrum of phase I and phase II metabolites, resulting in 26 T2 and 23 HT2 metabolites plus tentative isomers. A novel masked mycotoxin, 3-acetyl-HT2-glucoside, was reported for the first time in wheat. The in vitro approach confirmed its potential to both investigate the contribution of plant metabolism in the biosynthesis of masked mycotoxins and to foresee the development of biocatalytic tools to develop nature-like mixtures to be used as reference materials.

Ionic Energy

The primary object of the investigations described in this paper was the determination of the amount of energy required to produce a gaseous ion when Röntgen rays pass through a gas, and to deduce from it the energy of the radiation emitted per second by uranium, thorium, and other radio-active substances. In order to determine the “ionic energy” (as it will be termed for brevity), it has been necessary to make a special investigation to measure accurately the heating effect of X rays when the rays are absorbed in metals, and also the absorption of the rays in gases. The method employed to determine the ionic energy was briefly as follows :—The total energy of the rays emitted per second was determined by measuring the heating effect of a known proportion of the rays when absorbed in a metal. The total number of ions produced by complete absorption of the rays in the gas was deduced from measurements on the current produced by the ionization of a known volume of the gas and of the absorption of the rays in the gas, assuming the value of the ionic charge recently determined by J. J. Thomson.

Experience Of Flow

This chapter describes flow, the experience of complete absorption in the present moment, and the experiential approach to positive psychology that it represents. Flow theory and research have suggested one answer to the question of what constitutes a good life. The model of optimal experience and development that is associated with the concept of flow is summarized, and the chapter describes several ways of measuring flow, giving particular attention to the experience sampling method. Some recent research concerning the outcomes and dynamics of flow, its conditions at school and work, and interventions that have been employed to foster flow are reviewed. Finally, some of the promising directions for flow research moving into the future are identified.
