[Behavior of fat constitutents during refining. 8. Determination of polymeric fatty acids in rape seed oil and their behavior during refining].

1. Studies on rape-seed oil have shown that the determination of oxypolymers by means of the method according to Rost (determination of fatty acids insoluble in petroleum ether) yields unsatisfactory results. By way of contrast, the gravimetric determination (after isolation of the polymers via the non-urea adduct fatty acid methyl esters and thin-layer chromatographic separation), as proposed by the authors, permits to obtain results of good reproducibility and to determine thermopolymers and oxypolymers separately. 2. During the refining of rape-seed oil, it was observed that its polymer content decreased considerably on bleaching, and increased on deodorizing.

[Behavior of some parameters of lipid and energy metabolism. 1. Behavior of the stationary concentrations of acetyl CoA, acetoacetate and adenosine phosphates in liver, as well as oxygen consumption and P/O ratios in liver homogenates of growing rats on diets differing in fat content].

Young rats were maintained on diets differing in fat content. The determination of certain parameters of the lipid and the energy metabolism in the liver showed that a high-fat diet resulted in a reduction of the stationary level of acetyl CoA, an increase in the concentration of acetoacetate and a reduction of the adenosine triphosphate content and the so-called energy charge. In case of intact respiratory chain phosphorylation, the oxygen consumption of the respective liver homogenates was simultaneously increased. The results obtained with a high-fat diet are indicative of the attainment of a metabolic state which seems to be typical of metabolic regulations in growing rats subjected to anabolic lipometabolism.

Thought Field Therapy clinical applications: utilization in an HMO in behavioral medicine and behavioral health services.

Thought Field Therapy (TFT) is a self-administered treatment developed by psychologist Roger Callahan. TFT uses energy meridian treatment points and bilateral optical-cortical stimulation while focusing on the targeted symptoms or problem being addressed. The clinical applications of TFT summarized included anxiety, adjustment disorder with anxiety and depression, anxiety due to medical condition, anger, acute stress, bereavement, chronic pain, cravings, depression, fatigue, nausea, neurodermatitis, obsessive traits, panic disorder without agoraphobia, parent-child stress, phobia, posttraumatic stress disorder, relationship stress, trichotillomania, tremor, and work stress. This uncontrolled study reports on changes in self-reported Subjective Units of Distress (SUD; Wolpe, 1969) in 1,594 applications of TFT, treating 714 patients. Paired t-tests of pre- and posttreatment SUD were statistically significant in 31 categories reviewed. These within-session decreases of SUD are preliminary data that call for controlled studies to examine validity, reliability, and maintenance of effects over time. Illustrative case and heart rate variability data are presented.

Effect of lithium and other alkali metals on brain chemistry and behavior. II. Intracranial self-stimulation behavior.

Rats implanted with bipolar electrodes aimed at the medial forebrain bundle (MFB) were trained to self-stimulate. Six daily injections of 2 mEq/kg of the chloride salts of Li+, Rb+ or Cs+ were administered and the rate of intracranial self-stimulation (ICSS) was recorded. Lithium caused a reversible decrease in ICSS rate, beginning on the second day and returning to pretreatment rate on the fourth day of injections. The decrease was more pronounced in animals with high baseline rate (over 500 responses/10 min) than in low responders. Rubidium enhanced ICSS rate whereas cesium had no effect. These results agree with other accumulating data showing the opposite effects of Li+ and Rb+, but their relevance to effective disorders is not clear.

Behavioral influences on tolerance to the effects of morphine on schedule-controlled behavior.

Responding of pigeons was maintained under a multiple fixed interval, fixed ratio schedule of food delivery, and 10 mg/kg morphine was administered daily. Responding during both schedule components was initially decreased and measurable tolerance developed to this effect after four daily injections. However, the rate of tolerance development differed depending on whether or not presence of the drug coincided with performance during experimental sessions. Tolerance developed more rapidly when morphine was given before daily experimental sessions than when morphine was given daily but animals did not perform daily in experimental sessions. Tolerance to the rate-decreasing effects of morphine depended on relations between presence of the drug and exposure to experimental sessions.

Behavior genetics of choice of oviposition sites in Drosophila melanogaster. I. Genetic variability and analysis of behavior.

Females of Drosophila melanogaster were given a choice of oviposition site either on the surface of the medium or on the surface of paper positioned vertically on the medium. A significant difference was seen in the proportion of eggs deposited on the paper among wild strains of different geographic origins. Bidirectional selection for oviposition on these two sites was effective. These selected lines were examined under various conditions to determine the factors involved in this site selection for oviposition. The lines that chose medium laid eggs only on substrates into which eggs could be inserted. The lines preferring paper showed no strict requirement for burying their eggs. Tarsal sensillae were involved in site discrimination.

Sources of behavioral deviation modeled by early color preferences in quail. I. Behavioral synergism and systemic instability.

Differences between population-typical norms of individual variability were studied in five genetic lines of Japanese quail (Coturnix coturnix japonica); two (BL and RL) were bidirectionally selected for early approach preference between blue and red stimuli, two (Hi and Lo) for high and low imprintabilities to the same stimuli, and the fifth (CL) was an unselected genetic control line. Selection resulted in reliably divergent extreme choice performances and imprintabilities and in progressively increasing choice variances in the BL x RL hybrids and the Hi imprintability line. Experimentation tested and rejected the hypotheses that correlated selection of synergistically acting but otherwise extraneous stimulus influences, social interaction effects, or phototactic and short-term learning effects may have been responsible for the observed large variance increases. An alternative interpretation is discussed, according to which directional selection relaxes the genetic buffering and the variance increases reflect the resulting developmental instability of the trait.
