Parkinson's disease (PD) is a movement disorder characterized by the loss of dopaminergic neurons in the substantia nigra and the formation of intraneuronal inclusions called Lewy bodies, which are composed mainly of α-synuclein (α-syn). Selegiline (Sel) i ...
Visual comfort is a key element at work places and at home. Besides task illuminance and color rendering it is the indoor light distribution, which strongly impacts visual comfort. We aimed to show possible relations between subjective and objective visual ...
Cell-autonomous and self-sustained molecular oscillators drive circadian behavior and physiology in mammals. From rhythms recorded in cultured fibroblasts we identified the dominant cause for amplitude reduction as desynchronization of self-sustained oscil ...

Recent studies have attempted to link environmental cues, such as lighting, with human performance and health, and initial findings seem to indicate a positive correlation between the two. Light is the major environmental time cue that resets the human cir ...
The transcriptional circuits of circadian clocks control physiological and behavioral rhythms. Light may affect such overt rhythms in two ways: (1) by entraining the clock circuits and (2) via clock-independent molecular pathways. In this study we examine ...
Evening bright light exposure is reported to ameliorate daytime sleepiness and age-related sleep complaints, and also delays the timing of circadian rhythms. We tested whether evening light exposure given to older adults with sleep–wake complaints would de ...
Virtually every cell in our body tracks daily time using an endogenous mechanism called the circadian clock, which has a period of about 24 hours. This timing system offers a selective advantage by enabling organisms to anticipate periodic changes in envir ...
Mammalian physiology has to adapt to daily alternating periods during which animals either forage and feed or sleep and fast. The adaptation of physiology to these oscillations is controlled by a circadian timekeeping system, in which a master pacemaker in ...
This paper examines the effects of housing design upon the amount of natural light available for cuing of the human circadian system. It further assesses whether the conditions present in historic Boston row houses, when considered in the context of human ...
