The application of videodermoscopic examination in assessing the skin and its products in pure Arabian horses in the summer and winter seasons.

Videodermoscopic examinations have only recently started to be used in veterinary medicine and usually involve a small group of animals. The aim of this study was to compare specific dermoscopic parameters in selected areas of the body of Arabian horses in the summer and winter seasons. The research was conducted between 2018-2019.

An integration of hindsight bias and counterfactual thinking: decision-making and drug courier profiles.

Counterfactual thinking and hindsight bias have each generated separate, substantial bodies of research and provided insight into some areas of legal decision-making. An investigation of the relationship between counterfactual thinking and hindsight bias in a situation in which both are implicated is presented in a legal decision-making context utilizing drug courier profiles and illegal search and seizure. The findings, which demonstrate each of these cognitive processes and show a pattern of results that supports an integrative relationship between them, are discussed in the contexts of social cognition and of legal decision-making.

The naturalistic fallacy: moral inferences drawn from research with children versus adults.

The naturalistic fallacy occurs when a person reads a report of scientific research and concludes that the moral implication of the research was included in the article when, in fact, it was not. For example, the fallacy is committed when a study contains the conclusion that TV advertising increases preference for sugar-based foods, but the reader later believes that the study concluded that TV advertising should be controlled. Previous research indicates that the commission of the fallacy was strong when memory for social research was tested.

Effects of the hypocholesteremic agent trifluperidol on the sterol, steryl ester, and fatty acid metabolism of Saccharomyces cerevisiae.

Trifluperidol (TFP), at a concentration of 100 muM, inhibited the 24-h growth of Saccharomyces cerevisiae by about 30%. Effects on lipid metabolism were investigated by monitoring the incorporation of [1-14C]sodium acetate into various lipid fractions after 4 and 24 h of growth in the presence of several concentrations of TFP. Although little effect was noted on the amount of free sterols, 24-h incorporation of label into steryl esters was increased two- to fourfold by 100 muM TFP.

Extraction of lipids from yeast.

Several methods for the extraction of lipids from intact yeast cells have been compared. Extraction of intact cells with methanol followed by methanol: benzene (1:1, v/v) and benzene resulted in the recovery of equal or greater amounts of polar and nonpolar lipids than obtained by other methods. A preparative method involving preincubation of cells with aqueous KOH followed by the treatment of the cellular residue as described above yielded slightly more steryl esters than was extracted from broken cell preparations.
