Physiological responses of two arabidopsis thaliana isolates, N1438 and Col, to different salts

Field observations were made on the ecological life cycle of the winter annual Arabidopsis thaliana (L.) Heyn. from a population in central Tennessee, and a detailed laboratory study was conducted on the physiological responses of the seeds to temperature in light (14-h photoperiod) and constant darkness. At maturity and dispersal (late April and early May), seeds germinated to high percentages only at low temperatures (5–10 °C) in light. With storage from May to September and October (1) the maximum temperature for germination in light increased from 15 to 30 °C and in darkness from 10 to 20 °C and (2) the optimum temperature for germination in light increased from 5 to 15–20 °C and in darkness from 5 to 5–10 °C. During the spring–summer period seeds were dormant at temperatures simulating those in the natural habitat. In September and October, seeds in light germinated to high percentages at simulated September and October temperatures but did not germinate in darkness at the September temperatures and germinated poorly at October temperatures. Regulation of germination so that it occurs in early autumn allows A. thaliana to persist in a summer-arid habitat.

Pure Tone Audiogram

Purpose Misophonia is a sound tolerance disorder condition in certain sounds that trigger intense emotional or physiological responses. While some persons may experience misophonia, a few patients suffer from misophonia. However, there is a dearth of literature on audiological assessment and management of persons with misophonia. The purpose of this report is to discuss the assessment of misophonia and highlight the management option that helped a patient with misophonia. Method A case study of a 26-year-old woman with the complaint of decreased tolerance to specific sounds affecting quality of life is reported. Audiological assessment differentiated misophonia from hyperacusis. Management included retraining counseling as well as desensitization and habituation therapy based on the principles described by P. J. Jastreboff and Jastreboff (2014). A misophonia questionnaire was administered at regular intervals to monitor the effectiveness of therapy. Results A detailed case history and audiological evaluations including pure-tone audiogram and Johnson Hyperacusis Index revealed the presence of misophonia. The patient benefitted from intervention, and the scores of the misophonia questionnaire indicated a decrease in the severity of the problem. Conclusions It is important to differentially diagnose misophonia and hyperacusis in persons with sound tolerance disorders. Retraining counseling as well as desensitization and habituation therapy can help patients who suffer from misophonia.
