Temperature is a key factor influencing plant growth and productivity, however sudden increases in temperature can cause severe consequences terms of crop performance. We evaluated the influence elementary sulfur application on physiology two tomato genotypes (“Ahmar” “Roma”) grown chambers (at 25 45 °C). Plants were sprayed with 2, 4, 6, 8 ppm days after sowing (untreated plants kept as contro...

Despite its importance for development, relatively little is known about how allelic variation interacts with both pre- and postnatal stress. We examined the interaction between serotonin transporter (5-HTT) genotype, prenatal and postnatal stress on glucocorticoid receptor (GR) mRNA expression, corticosteroid stress responses, and behavior in adult male rats. Prenatal stress involved a daily r...

OBJECTIVE To describe the anatomy of bone and the physiology of bone remodeling as a basis for the proper management of stress fractures in physically active people. DATA SOURCES We searched PubMed for the years 1965 through 2000 using the key words stress fracture, bone remodeling, epidemiology, and rehabilitation. DATA SYNTHESIS Bone undergoes a normal remodeling process in physically act...
