Background: Bright light therapy, an effective therapeutic option for depressive adults, could provide safe, economic, and effective rapid recovery also in adolescents. Method: This was a randomized cross-over trial, i.e. that 14 patients received first dim white light (50 lux) one hour a day for one week and then Bright light therapy (2500 Lux) for one week. 14 patients received first Bright l...

We have recently introduced a new language, called Opus, which provides a set of Fortran language extensions that Mlow for integrated support of task and data parMlelism. It also provides shared data abstractions (SDAs) as a method for communication and synchronization among these tasks. In this paper, we first provide a brief description of the language features and then focus on both the lang...

Four groups of normal rats have been studied to elucidate the effect on the time of birth of four different light regimes applied throughout pregnancy (day 1: beginning of pregnancy). The results showed that the time of parturition (onset of expulsion) depended on the light treatment: the longer the duration of the daily illumination, the longer pregnancy lasted. With a 14 hrs light regime, the...

BACKGROUND Day/night cycles regulate the circadian clock of organisms to program daily activities. Many species of microalgae have a synchronized cell division when grown under a day/night cycle, and synchronization might influence biomass yield and composition. Therefore, the aim of this study was to study the influence of day/night cycle on biomass yield and composition of the green microalga...

BACKGROUND AND OBJECTIVE Prior studies have suggested that after stroke there is a time-limited period of increased responsiveness to training as a result of heightened plasticity-a sensitive period thought to be induced by ischemia itself. Using a mouse model, we have previously shown that most training-associated recovery after a caudal forelimb area (CFA) stroke occurs in the first week and ...

Chrysanthemum ( × morifolium ) is a common ornamental crop with qualitative short-day flowering response. Extending short day moderate blue [B (400–500 nm)] light inhibits in greenhouse conditions sunlight but does not indoors (without sunlight) under B + red [R (600–700 or white light. We postulated that the contrasting responses to as extension depended on far-red [FR (700–800 during day, whi...

Background: Exposure to electromagnetic radiation may impair memory. This study was conducted to evaluate the effect of radiofrequency wave (hereafter referred to as RFW) on passive avoidance learning and memory in healthy males and females. Materials and Methods: Ten adult male and ten female Sprague-Dawley rats (230±20 gr) were randomly divided into four groups including two control groups (o...

Recently much attention has been paid by horticulturists to light-emitting diodes as a new source of economical and spectral-selective light. The reason is mainly coming from their versatility in handling and mounting, long working time, wattage use efficiency and lower heat production. In this study we examined their potential in promoting seed germination and producing quality flower seedling...
