The effect of aspartame on circadian rhythms of calcium and inorganic phosphorus levels was studied in rats. Acrophase delays in calcium rhythms and advances in inorganic phosphorus rhythms and alteration in mesor values in both rhythms were observed in aspartame-treated rats. However, no change in amplitude values was observed. Oral administration of aspartame leads to increased levels of aspa...

BACKGROUND Catheter-based renal sympathetic denervation (RDN) has been considered a potential treatment for therapy resistant hypertension (RHT). However, in a randomized placebo-controlled trial, RDN did not lead to a substantial blood pressure (BP) reduction. We hypothesized that variation in the reported RDN efficacy might be explained by incomplete nerve disruption as assessed by renal 123I...

The rice slender mutant (slr1-1) is caused by a single recessive mutation and results in a constitutive gibberellin (GA) response phenotype. The mutant elongates as if saturated with GAs. In this mutant, (1) elongation was unaffected by an inhibitor of GA biosynthesis, (2) GA-inducible alpha-amylase was produced by the aleurone layers without gibberellic acid application, and (3) endogenous GA ...

Quantitative trait loci (QTLs) for shoot biomass were identified in wheat grown on a soil high in total phosphorus (P) but low in plant-available P. The two populations screened included recombinant inbred lines (RILs) from Chuan-Mai 18/Vigour 18 and doubled-haploid lines from Kukri/Janz. Glasshouse-grown plants were harvested at the five-leaf stage. Seven QTLs for shoot biomass were identified...

Successive single day transfers of pot-grown wheat to high temperature (35/30°C day/night) replicated controlled environments, from the second node detectable to the milky-ripe growth stages, provides the strongest available evidence that the fertility of wheat can be highly vulnerable to heat stress during two discrete peak periods of susceptibility: early booting [decimal growth stage (GS) 41...

The endogenous pacemaker activity of the suprachiasmatic nuclei (SCN; the master clock in mammals) is regulated by photic information relayed from the retina to the SCN via the retinohypothalamic tract (RHT). Recent work has revealed that glutamate and pituitary adenylate cyclase-activating polypeptide (PACAP) are stored in RHT nerve terminals and function in a coordinated manner to regulate cl...

Heading date in wheat (Triticum aestivum L.) and other small grain cereals is affected by the vernalization and photoperiod pathways. The reduced-height loci also have an effect on growth and development. Heading date, which occurs just prior to anthesis, was evaluated in a population of 299 hard winter wheat entries representative of the U.S. Great Plains region, grown in nine environments dur...
