  Title Color recognition and discrimination under full-moon light Type (up) Journal Article
  Year 1994 Publication Applied Optics Abbreviated Journal Appl Opt  
  Volume 33 Issue 21 Pages 4741-4748  
  Keywords Human Health  
  Abstract The ability to recognize and discriminate colors under full-moon light was measured Color naming was performed at three sizes (0.5 degrees , 2 degrees , and 4 degrees ) by the use of one white and six colored chips that spanned the spectrum at two levels of saturation. The results show that correct color recognition is possible under full-moon light. However, the recognition rate depends on a complex interaction between hue, level of saturation, and size of test field. For small fields and desaturated colors, the recognition rate is low. However, for saturated colors, most hues can be recognized at better than chance levels, with red being recognized very accurately.

  Title Night light alters menstrual cycles Type (up) Journal Article
  Year 1990 Publication Psychiatry Research Abbreviated Journal Psychiatry Research  
  Volume 33 Issue 2 Pages 135-138  
  Keywords Human Health; Light; menstruation; phototherapy  
  Abstract Dewan asserted 20 years ago that a bedside light could shorten and regularize the menstrual cycle among women with long and irregular menstrual patterns. To replicate this, seven volunteers slept with a 100-watt bulb by the bedside from days 13–17 of their menstrual cycles, while nine controls similarly used a dim red placebo (photographic safe light). Indeed, the 100-watt bulbs shortened menstrual cycles from a mean of 45.7 days to 33.1 days and reduced variability, but the placebo had no effect. These results suggest that light may have promise for treatment of infertility, for contraception, and for other endocrine interventions.

  Title Light suppresses melatonin secretion in humans Type (up) Journal Article
  Year 1980 Publication Science Abbreviated Journal Science  
  Volume 210 Issue 4475 Pages 1267-1269  
  Keywords Human Health  
  Abstract Bright artificial light suppressed nocturnal secretion of melatonin in six normal human subjects. Room light of less intensity, which is sufficient to suppress melatonin secretion in other mammals, failed to do so in humans. In contrast to the results of previous experiments in which ordinary room light was used, these findings establish that the human response to light is qualitatively similar to that of other mammals.

  Title The genetic background of individual variations of circadian-rhythm periods in healthy human adults. Type (up) Journal Article
  Year 1993 Publication American Journal of Human Genetics Abbreviated Journal  
  Volume 52 Issue 6 Pages 1250–1259  
  Keywords Human Health; Adult; Body Temperature; Bronchi; Bronchi: physiology; Circadian Rhythm; Circadian Rhythm: genetics; Female; Genetic Variation; Hand; Hand: physiology; Heart Rate; Humans; Male; Middle Aged; Sex Factors; Sleep  
  Abstract As a group phenomenon, human variables exhibit a rhythm with a period (tau) equal to 24 h. However, healthy human adults may differ from one another with regard to the persistence of the 24-h periods of a set of variables' rhythms within a given individual. Such an internal desynchronization (or individual circadian dyschronism) was documented during isolation experiments without time cues, both in the present study involving 78 male shift workers and in 20 males and 19 females living in a natural setting. Circadian rhythms of sleep-wake cycles, oral temperature, grip strength of both hands, and heart rate were recorded, and power-spectra analyses of individual time series of about 15 days were used to quantify the rhythm period of each variable. The period of the sleep-wake cycle seldom differed from 24 h, while rhythm periods of the other variables exhibited a trimodal distribution (tau = 24 h, tau > 24 h, tau < 24 h). Among the temperature rhythm periods which were either < 24 h or > 24 h, none was detected between 23.2 and 24 h or between 24 and 24.8 h. Furthermore, the deviations from the 24-h period were predominantly grouped in multiples of +/- 0.8 h. Similar results were obtained when the rhythm periods of hand grip strength were analyzed (for each hand separately). In addition, the distribution of grip strength rhythm periods of the left hand exhibited a gender-related difference. These results suggested the presence of genetically controlled variability. Consequently, the distribution pattern of the periods was analyzed to elucidate its compatibility with a genetic control consisting of either a two-allele system, a multiple-allele system, or a polygenic system. The analysis resulted in structuring a model which integrates the function of a constitutive (essential) gene which produces the exact 24-h period (the Dian domain) with a set of (inducible) polygenes, the alleles of which, contribute identical time entities to the period. The time entities which affected the rhythm periods of the variables examined were in the magnitude of +/- 0.8 h. Such an assembly of genes may create periods ranging from 20 to 28 h (the Circadian domain). The model was termed by us “The Dian-Circadian Model.” This model can also be used to explain the beat phenomena in biological rhythms, the presence of 7-d and 30-d periods, and interindividual differences in sensitivity of rhythm characteristics (phase shifts, synchronization, etc.) to external (and environmental) factors.
