“…DA is well known to increase testosterone secretion. Serotonin [tryptophan feeding] may act antagonistically to DA with respect to reproductive regulation [86,87]. Declining sexual function in male rats likely reflects central deterioration (including loss of gonadotropin releasing hormone neurons) rather than alterations in sex hormones.…”

Dopamine and Aging: Intersecting Facets

Aging encompasses life itself so understanding requires frameworks that forge unity amidst complexity. The free radical theory of aging is one example. The original focus on damage was augmented recently by appreciation that reactive oxygen and nitrogen species are essential to normal signaling and cell function. This paradigm is currently undergoing an explosive expansion fueled by the discovery that regulatory organization is a merry-go-round of redox cycling seamlessly fused to endogenous clocks. This might best be described as an "Electroplasmic Cycle." This is certainly applicable to dopaminergic neurons with their exceptional metabolic, electrical and rhythmic properties. Here I review normal aging of dopamine systems to highlight them as a valuable model. I then examine the possible integration of free radical and ion channel theories of aging. Finally, I incorporate clocks and explore the multifaceted implications of electroplasmic cycles with special emphasis on dopamine.

This study was conducted to consider the effect of theophylline in laying and some of egg characteristics on laying hens. Commercial egg type Hy-Line hens were used in a completely randomize design with 4 treatments and 3 replicates for 50 days period. The levels of different theophylline supplements (treatment) were 0 (control), one, three, and five mg per kg of body weight for 50 days. The average data were compared by using Tukey-Kramer multiple comparison tests. All levels of theophylline significantly increased laying performance. The best laying performance was observed in 3 mg/kg of theophylline. The best effect on egg size, weight, yolk and albumen height was found in hens receiving highest concentration of theophylline (p≤ 0.05). All levels of theophylline significantly decreased yolk color index (p≤ 0.05). The lowest yolk diameter was observed in 3 mg/kg theophylline. The highest albumen Haugh unit was in 1 mg/kg theophylline (p≤ 0.05). Results showed that theophylline increased the rate of laying and some of egg characteristics in hens. The best laying performance was showed in 3 mg/kg and the highest egg weight and size in 5 mg/kg of body weight theophylline.
